Overview of Concert Stage Lighting - Music

A concert lighting designer's job is to plan and execute lighting effects that convey a specific mood or concept, illuminate the performer, and engage an audience. With access to the best lighting equipment and knowledge of advanced lighting techniques, today's concert lighting design has become very sophisticated. Concert lighting designers must be familiar with a variety of lighting equipment and often take years to master the art of lighting a large production.

Below is an overview of some of the lights most commonly used by concert lighting designers. Floodlights & spotlights are the two primary types of stage lights. Floodlights generally produce a wide beam of light that can illuminate large stage areas while spotlights produce and narrow, more focused beam of light.

There are several sub-categories of both floodlights and spotlights as well as some lighting equipment that falls in between the two categories. PAR (Parabolic Aluminized Reflector) lights are a type of floodlight often used for rock concerts. This lamp produces a large amount of flat light that comes from a unit that resembles an empty paint can.

PAR lights are often used in conjunction with smoke or haze effects. The benefits of these lights are that they are lightweight, portable, and low cost. Strip lights are strips of lighting housing containing many lamps.

Typically, strip lights are used to illuminate wide areas of a stage, such as a back curtain. While colors for lighting are often achieved by "gels" or colored plastic that go over a light, strip lights use glass gels, or "roundels" to produce colored light. One of the main advantages of strip lights is that a separate electrical dimmer circuit can control each lamp.

LED Lights are another popular concert lighting element. Because this type of light uses light emitting diodes, or LEDs, rather than halogen lamps, they can produce lots of light while consuming less power than traditional stage lights. Popular with concert designers, these lights are able to produce a wide range of vibrant colors to create interesting lighting effects.

Spotlights are also essential to concert lighting equipment. They produce an intense beam of light that can illuminate an entire stage. These lights come in several varieties, each with unique properties.

Fresnels are smaller light fixtures that produce a pool of light or a concentrated, but soft edged spot. Profile lights are most similar to what people associate with traditional spotlights. Their convex lenses produce a sharp light beam that can be formed into different shapes of an insert called a gobos.

Finally, PC's, or Pebble Convex lanterns use convex lenses with a pebbled effect that produce a concentrated spot of light with little "spill" outside the target. An excellent concert lighting designer is familiar all of lighting equipment mentioned here in addition to much more advanced equipment. More importantly, they know how to plan and execute lighting for a 2-3 hour concert with the utmost precision and creativity.

Those who excel in the art of concert lighting have the privilege of working with top touring artists such as Motley Crue and Maroon 5. One example of a live concert video production company that is putting their name on the map is Daddy Van Productions, based out of Austin, Texas.

London 2012 Basketball Arena / Wilkinson Eyre Architects
Edmund Sumner Architects: Wilkinson Eyre Architects Location: Olympic Park North (Stop M), London Borough of Hackney, London E9, UK Project Team: SKM with Wilkinson Eyre Architects and KSS Project Year: 2011 Project Area: 11500.0 sqm Photographs: Edmund Sumner The Basketball Arena by Wilkinson Eyre Architects is one of the biggest temporary venues ever erected for any Olympic and Paralympic Games and the third largest venue in the Olympic Park. Located on high ground at the north end of the site, and clearly visible from various vantage points in the Olympic Park, the Arena will provide 12,000 seats for the basketball heats and handball finals, as well as 10,000 seats for the wheelchair basketball and wheelchair rugby competitions. Despite a tight budget, the Arena is set to be one of the most iconic and visually dramatic buildings of the 2012 Games. Edmund Sumner The brief called for a structure that was simple to erect but also provided a worldclass sporting venue for some of the most popular Olympic events. Alongside these factors, sustainability was a key driver in the buildings design: the arena has been made out of robust individual components that can be easily dismantled and subdivided for reuse, with over twothirds of the materials and components used on the project identified for reuse or for recycle. Section 03 Wilkinson Eyre has used an architectural language that remains distinct from the surrounding permanent venues, overtly celebrating both the best of British engineering and the temporary nature of the structure through innovative and economic structural and cladding solutions. Lightweight, simple building components have been used instead of a concrete structure usually found in stadia architecture, allowing the Basketball Arenas steel frame and cladding to be constructed in just six weeks. Edmund Sumner The 30mhigh rectangular volume (the equivalent of a sevenstorey building) is made out of a steel portal frame and wrapped in 20,000 sqm of lightweight phthalatefree and recyclable PVC. This translucent bespoke cladding is stretched across minimal steel framing modules that push the fabric out and create an elegant and threedimensional undulating pattern across the facades. The roof fabric includes an interwoven blackout layer that eliminates daylight during game sessions and maintains fully controllable artificial lighting for the media. The external walls are translucent, allowing daylight to filter through during the day and artificial lighting to be visible in the evening. Edmund Sumner The variation of surface qualities used throughout the structure help animate the buildings exterior, with the expression of the building being derived from the play of sunlight and nighttime theatrical lighting across the fabric surface. Wilkinson Eyre worked with United Visual Artists, specialists in concert lighting and installations, to create lighting and colourchanging effects for the evening games. The result is a dynamic illumination which, at night, transforms the white surface into a variety of saturated colours and strong silhouettes of the substructure, creating the biggest light installation on the Olympic park. Edmund Sumner Modular accommodation units that serve as the back of house areas are located outside the Arena volume, which also shares LOCOG overlay facilities with the Velodrome and BMX Track. These will include warmup courts and areas for catering, security, waste management and the media. Diagrams 01 Wilkinson Eyre worked Sinclair Knight Mertz (project management, structural and MEP consulting) and sports consultants KSS on the project.

Three Musketeers at Synetic Goes Full Throttle on the Senses
Nearly everything Synetic Theater does could be called Fast and Furious, and the movement-based troupes relentless new The Three Musketeers opens with a tiger pounce as four actors leap out of the darkness toward the audience. Explosive music accompanies the frenzied sword fight; it looks and sounds like a movie trailer for a summer blockbuster.Who are these characters? Doesnt matter. Whirl. Clang. Spin. Punch. Zow! This is how Synetic rolls: The playwright, Ben Cunis (who adapted the famed Alexandre Dumas novel with his brother Peter), not only plays the dashing musketeer Athos, he also does the fight choreography. Thats not vanity. It simply describes the skill set, and the company mind-set. How, they ask, can the story move? Unlike the silent Shakespeare productions (all motion, no speaking) that have won Synetic so much acclaim, Musketeers features plenty of talking, and the Cunis brothers dialogue sometimes manages a kind of cornball charm. Ben Cunis delivers a wry, Kevin Kline-ish performance as the suave but drunken Athos, and Hector Reynosos blustery turn as the plus-sized musketeer Porthos is part of why this light-spirited Musketeers occasionally puts you in mind of The Princess Bride. Director Paata Tsikurishvilis plus-sized production has 16 actors creating crisscrossing mayhem on Synetics Crystal City stage. (Dont even think of going if youre not in the mood for more than two hours of almost manic adventure.) The first swashbuckling act comes off like half-popped popcorn, but you have to giggle at the unapologetic hamminess served up after intermission. If Cunis infectiously enjoys himself as a comic hero, Dan Istrate performs with no less relish as the dastardly, power-grabbing Cardinal Richelieu. The red leather robes and kinky black corset by designer Anastasia R. Simes (who also did the multilevel set thats so ripe for chase scenes) gives Istrate something wicked to live up to, and the actor responds with a creepy turn that pushes the show toward a pulpy edge. But wait theres another villain, and this one dances! Irina Tsikurishvili, as the spidery Milady, tangos with Istrate (Miladys in cahoots with the Cardinal), spins with Cunis (Milady and Athos used to be married long story) and drop-kicks rivals with the aggression of a ticked-off Angelina Jolie. Silly? Yes, but then we havent even come to Robert Bowen Smiths gaudy, low comic vamp as the mincing menace King Louis XIII, resplendent in an all-white, open-collar getup that slightly recalls a latter-day Elvis. None of this is simple, and it rarely looks easy. The actors are in a full sweat mere moments into the show, and while the athleticism is part of what typically impresses with Synetic, so is the discipline. The punches and swordplay are quick, and the tumbling is fearless. Dallas Tolentino is winningly cheerful as the young musketeer-in-training DArtagnan, but the hallmark of his performance and of the show is soaring jumps and nailed landings. The production revs with sensory appeal, from Brittany Dilibertos rock concert lighting design to the sinister/bombastic music by Konstantine Lortkipanidze. This is Synetic at full throttle, although fueled far more by energy than wit. This Musketeers isnt stupid, but its exhausting; while some audiences will be thrilled by the restless propulsion, its fair to wonder if this one-of-a-kind troupe is in danger of getting stuck with its foot on the gas pedal. by Alexandre Dumas. Adapted by Ben and Peter Cunis. Directed by Paata Tsikurishvili. Choreography, Irina Tsikurishvili; sound design, Thomas Sowers. With Matthew Ward, Brittany OGrady, Brynn Tucker, Peter Pereyra, Mitchell Grant, Vato Tsikurishvili, Zana Gankhuyag, Rebecca Hausman, Kathy Gordon and Kathryn Elizabeth Kelly. About 2 1 / 2 hours.

Teen Angst Is Everywhere in Keegans Spring Awakening and Cuchullain
The Mrs. Grundys of this world might want to give a wide berth to the Church Street Theater for a few weeks: The two spirited and affecting productions running in that venue, courtesy of the Keegan Theatre, present visions of youthful ids running wild.In a taut and stirringly acted version of the Steven Sater-Duncan Sheik musical Spring Awakening, based on Frank Wedekinds 1891 drama, adolescent characters grapple with sexuality and rage at the repressive adult world. And in Rosemary Jenkinsons world-premiere play Cuchullain, an endearingly impulsive and foul-mouthed modern 19-year-old ingests drugs and alcohol as if hed worked out a personal immunity deal with mortality.If the theme of teenage rebellion unites both works, it has a more profound edge in Spring Awakening. Co-directors Mark A. Rhea and Susan Marie Rheas production of the Tony-winning musical (whose touring incarnation hit the Kennedy Center in 2009) features a cast of gifted young actors who turn in eloquent portraits of passion, frustration and vulnerability. In the shows opening sequence, the heroine Wendla (Ali Hoxie) cuts a wistful figure as she stands on a terrace, unleashing the yearning in the number Mama Who Bore Me. (As is the case with other performers in the production, Hoxie has a melodious voice that will no doubt gain strength later in her career. Music director and pianist Jake Null leads the fine 10-person orchestra, which sits onstage, beneath the terrace. Mark Rhea designed the set.)Minutes later, on the stages main level, schoolboy characters in gray uniforms storm through the song The B---- of Living, stomping on the floor, brandishing chairs like shields and, in the case of one performer, bouncing soles of the feet making contact, body horizontal off the theaters side wall. (Assistant director Kurt Boehm is choreographer.) The energy that surges through this number and through Allan Sean Weekss rock-concert lighting design courses, subtly or obviously, through the entire production.Some aspects of the staging that stomping sequence, for instance, or the wintry tree-branch pattern on part of the stages surface carry strong echoes of the Broadway version. And actors Charlotte Akin and Jon Townson sometimes fold a little too much caricature into their interpretations of adult figures. But its hard to quibble when the package as a whole is so effective. Vincent Kempski is particularly charismatic as the smart, mutinous hero Melchior: The scene in which Melchior first strikes up a conversation with Wendla is a triumph of adolescent awkwardness, all pauses and averted gazes and simmering chemistry. The vocally gifted Paul Scanlan brings a persuasive desperation and restlessness to the misfit Moritz, Nora Palka is poignantly scarred and waifish as the outcast Ilsa, and Sarah Chapin radiates trauma as an abused girl named Martha.Teenage disaffection has a more upbeat tone in Cuchullain, a one-actor show that as Jenkinsons Basra Boy did last year careens through a seedy Belfast cityscape populated by vibrant eccentrics. Performer Josh Sticklin, who infused Basra Boy with humor and zest, is equally irresistible as the hedonistic 19-year-old Aaron, whose idea of gainful employment is doing drugs in the park and then convincing a social services office that he is mentally ill (and thus deserving of generous welfare support).Aarons sordid tale should, by rights, be a downer. But, as embodied by Sticklin jeans, T-shirt, red sneakers, spiky hair, animated body language the character is so exuberant and oddly innocent that to share his company is to be caught up in an exhilarating whirl of adventure, impish defiance and consoling camaraderie. (Basra Boy director Abigail Isaac repeats her staging duties here.)Jenkinsons script brims with slangy poetry and infectious rhythms. Aaron describes a nurses eyes as spinnin around like two fruits in a slot machine, and he hears sea gulls cryin high like banshees as he escapes a crime scene in a car thats a rave-on-wheels. (A handout supplies a helpful glossary to Belfast idioms.) Shimmying up a flagpole to steal an Irish tricolor, skidding down a park slope while high on pills whatever hes doing, Aaron seems to experience life in a rush of intensity. Watching him, we do, too.

What Sound Bursts Your Bubble?
Alley cat! The cat that's always in New York backstreets or other scary urban areas.Shop door bell is also one of those sounds...I live in Sweden and some studios here are just plain lazy and choose whichever sample is the closest. So it turns out that every door and every shop has the same sound.And there is also abuse of an owl sound here in Sweden whenever we show images of dark forests there the certain "hoot hoOOot" and it just... well. Much like the loon. There's a great movie called "in a better world" or "hmnden" (the swedish title). The movie is danish so of course it's hyper realistic in acting and events. Everything "feels real" and it's a breathtaking movie, really stunned me. And it had its grip on me, I had been crying and had a real physical emotional experience of this movie and this freakin' owl just starts hooting! Why? Cause there's an image of a forest with a lake nearby. GAHSo even danish sound designers are lazy, it seems. Actually the sound of that movie in general was quite mediocre. :/ OT: But nonetheless a fantastic movie that I greatly recommend :)When enjoying media for entertainment purposes, what specific sounds shatter your suspension of disbelief?For me, it is the call of a loon. I grew up in Muskoka, which is a cottage district in Ontario. My ears prick up whenever I hear that bird song. I am immediately transported to memories of starry nights camping, or sitting on a dock at dusk.Yesterday, while watching 24 S01E02, I heard a loon call out in the Mojave desert. Maybe they migrate that far... maybe... but still - it made me chuckle.The biggest example of a bird song that ALWAYS cracks me up is approximately 3 minutes into Thriller by Michael Jackson."They're out to get you. Demons closing in on every side." CUE LOON.
Share the Design and Application of a Practical ATX Power Supply
1 Introduction to ATX power supplyThe switching power supply in early PC was dominated by at power supply. The output power of at power supply is generally 150 250W, with four outputs ( 5V, - 5V, 12V, - 12V). In addition, it also provides a PG (power good) signal to the main board. The disadvantage of at power supply is that it can not realize software shutdown by cutting off AC power supply. At present, with the popularity of ATX power supply, at power supply has faded out of the market.Intel introduced the popular atx2.01 power supply standard in 1997. Compared with at power supply, ATX power supply mainly increases 3.3V output voltage and a PS-on signal. Among them, the 3.3V power supply supplies power to the CPU using low voltage, which greatly reduces the power consumption of the motherboard circuit. 5V power supply, also known as auxiliary power supply, has 5V voltage output as long as 220V AC is plugged in. PS-on signal is the level signal provided by the motherboard to the power supply, which is used to control the output of other voltages of the power supply. The functions of software startup / shutdown and network remote wake-up can be realized by using 5V power supply and PS-on signal. When the PS-on signal sent by the motherboard to the power supply is low, start the power supply, and turn off the power supply when PS-on is high. The main technical indexes of ATX power supply are output power, safety standard (such as China's C CEE certification), electromagnetic interference (EMI) characteristics, "power failure" (PF, i.e. power failure) and delay time of "power normal" signal.The power of PC switching power supply must meet the needs of the whole machine and leave a certain margin. At present, PC is developing towards "green" energy-saving and environmental protection, and its power supply power is not the greater the better. Intel's new micro ATX standard stipulates that the PC power supply power is only 145W, and can even be reduced to 90W. ATX power supply has become the mainstream product of PC power supply.2 basic principle of voltage stabilizing circuit of magnetic amplifierThe basic principle of magnetic amplifier voltage stabilizing circuit in flyback switching power supply is shown in Figure 1. The output voltage uo passes through the sampling resistors R1 and R2 to obtain the sampling voltage UQ, which is connected to the inverting input end of the error amplifier, the in-phase input end of the error amplifier is connected to the reference voltage UreF, vdz is the regulator, and R3 is the bias resistance. The error amplifier compares UQ with UreF to generate error voltage ur, which is then connected to the right end of controllable magnetic saturation inductor L1 through diode VD3. VD1 is the output rectifier and VD2 is the freewheeling diode. C is the output filter capacitor. L2 is a magnetic bead used to suppress switching noise. U1, U2 and U3 represent the voltages at the left end of L1, the right end of L1 and the right end of VD1 respectively. The upper end of the primary side of the high frequency transformer is connected with the DC input high voltage U1, and the lower end is connected with the drain of the power switch MOSFET. The feedback signal obtained by the output voltage through the feedback circuit is used to adjust the pulse duty cycle of the PWM modulator. The purpose of voltage stabilization can be achieved by changing the on and off state of the MOSFET.When the MOSFET is turned on, the energy is stored in the high frequency transformer, and VD1 is cut off. When the MOSFET is turned off, the energy stored in the high frequency transformer is transmitted to the secondary side. At this time, VD1 is turned on, and the magnetic reset current Ig flows through L1 from right to left to reset L1. Since the direction of secondary winding current I2 is opposite to Ig, I2 must offset Ig before flowing through L2. This shows that the secondary side current changes from negative to positive, and then increases rapidly, so that L2 enters the magnetic saturation state and presents low impedance. Obviously, the magnetic reset time is the delay time T1 when VD1 begins to turn on.The timing waveform of the magnetic amplifier is shown in Fig. 2 (a) and (b). The corresponding magnetic reset times are T1 and T2 respectively.It can be seen from the figure that changing T1 can adjust the duty cycle of U2: D = T1 / T, t is the switching cycle. Specifically, when the magnetic reset time is reduced from T1 to T2, D ↑ → uo ↑. Conversely, when the magnetic reset time increases from T2 to T1, D ↓→ uo ↓. Because the magnetic amplifier has the function of "secondary voltage stabilization" (the primary voltage stabilization is completed by PWM modulator), it can accurately adjust uo and obtain high stable output voltage.
LG Will Push Cordless Stick Vacuum Cleaner with Charging Station
LG will announce a new cordless stick vacuum cleaner on CES 2021, which includes a charging station that can automatically empty the dust box before filling the battery. The charging station for automatic emptying robot vacuum cleaner has existed for some time, but the new cordzero thinq A9 kompressor is the first stick vacuum cleaner we see, which can completely and automatically remove the dust in the dustbin.This is the first work of the charging station when the cordless stick vacuum cleaner stops. It automatically sucks the compressed contents of the dustbin into the additional bag, although there is a switch to manually start the dustbin cleaning. After that, the charging process can begin. Other settings can be adjusted using the touch screen of the charging station.This vacuum cleaner provides one key control and is equipped with a 2-in-1 combination tool, a gap tool, a pet nozzle, a special nozzle for cleaning carpets, an accessory to turn the device into a mop, and includes a spare quick replacement battery, so that users can solve the cleaning work for a longer time without stopping to charge, The filter is removable and washable.LG did not give more information about A9 kompressor. It will make its debut at next week's CES virtual conference, but the existing models have cyclone dust collection system, HEPA filter, telescopic straw and support Wi Fi, which can be used with supporting applications. At present, there is no news about the price and supply.Editor ajx
I Have a Sony W810i Sell Phone and the Back Lights Dont Work, Can Anyone Tell Me How Could I Fix It
you've got a couple of options, send it back to SE and have them re-flash the phone or search their web page (or the internet in general) for the flash software and do it yourself. Hopefully this will solve the problem. As always, try basic trouble shooting first - like remove the battery and put it back in, perform a master reset on the phone -- all that good stuff. Good luck• Suggested Readingusing cell phone when your waiting at the traffic light when it is red.?You cannot use a cell phone while you are operating a motor vehicle. Stopped at a red light is still operating your vehicle. Once you park the car, you are no longer operating, and can make your call.Hand-free should be allowed (I can't find anything saying it's not). But when you go to court, it will come down to your word against the officer's. So make sure you have some type of proof other than just saying you were using hands-free.------The light on my cell phone (front screen) will not go off?Here you go...... With your flip open, you need to press Menu, then Settings or Tools, (might say Settings & Tools), then Phone Display, and you should probably be able to figure it out from there.Also, here's the manual for your phone in pdf format.

My Samsung Black Jack 2 Screen Light Keeps Turning ON/OFF?I own a Samsung phone and it's pretty sturdy. But whenever my phone starts acting up I usually turn it off and then back on to see if the problem is fixed. If not, I try taking out the battery and see if that works. If nothing works you should go bring it to the store. If you have a warranty and your phone shows no signs of water damage i think they'll replace it for you------Does my cell phone light up before it rings because light travels faster than sound?No, and the answer isn't physics, it's the design of your phone's software. The software designer probably decided to tell you (using the light) that negotiations between the phone and the cell tower started, but the phone does not yet know whether it's a voice call or a text message, whether any cell tower has a good enough round-trip radio connection to support a call, and which tower has the best connection. Once that's all settled and decided, the phone makes a sound.------what kind of verizon phone should i get?The Palm Centro!! It's small enough to fit in your pocket, and it's very light.

I NEED cool phone cuz my PDA broke, it's like 20 years old, and i'm only 11, so thats hardly suprising. On my Laptop i can play Tapica! YAY! But thats about it... Its only a Win 3.1
Need to Get My Computer Working!?
Have you tried clicking "Last Known Good Configuration (your most recent settings that worked)"? EDIT If none of that worked, it means that either your hard drive has failed or is about to fail. You need to replace it. If you need to get stuff off it , see if this works.Restart the computer and keep pressing "delete" to get to the bios screen. It's different for various motherboards, but probably under "Hard disk", turn off the SMART function. Save and exit. If it boots into Windows, start saving on to disk or memory, everything you want to save and keep or move it to a new hard drive. This drive is about to fail, do not waste any time!!! If it does not boot into Windows, the drive has already failed.— — — — — —Help computer not working please help?If the whole heat sink came off do not use the computer. There is CPU paste under the heatsink that is put on before the heat sink on. When the air hits that(after you took it off) it pretty much makes that paste useless. The thermal paste needs to be re-applied before you use the computer or else the CPU will overheat and you will fry your CPU. If it's under warranty, send it back. If it is not , take it to a local computer shop and tell them what happened and ask them to fix it. Hope this helps— — — — — —is my computer a good gaming computer?There a several submodels of the G71. It's unlikely that Fallout NV will run well, if at all on your computer— — — — — —Is this a good computer?It wont be used for gaming, I can tell you that much (unless you are talking about flash games or very old/low requirement games)— — — — — —Connect computer to HDTV wirelessly?It sounds like your hyperlinked product will work. I basically have a flat screen HDTV and I want to be able to sit--with my laptop on my lap--and view the computer on my TV wirelessly--as if it were the actual monitor.— — — — — —What could be wrong with the computer or router?change the cat 5e cable aka the cable that goes from the router to the computer— — — — — —Computer: the video stutters and there is a buzzing noise!?Make sure that the speakers are as far away from the monitor or the computer as reasonable. Speakers might be creating a magnatic field that will effect the moniter.— — — — — —Pcm and computerReason being is the '93 is an OBD1 computer and the '99 is an OBDII computer. Like they say above, you need the computer & wiring harness from the '99 to run the '99 motor.— — — — — —Can a gaming computer double as a studio computer?i would say yes because it is already a high end computer— — — — — —My computer won't turn on?i still think is the charger or the connection of the charger on the laptop but most likely is the charger why? you say well because you said that when you connected the charger to the laptop the battery icon did not change so it was not charging the charger getting hot is normal and the green light on it not always indicates if there is a problem with it, why did the laptop turned off after you left it alone? Because the battery died, it has no charge and the charger is not charging it. what about the windows was unable to start? it happens some times might have been just some kind of glitch that usually gets fixed just by restarting the computer now something you did not mention is if the light on the computer that indicates when the computer is charging or is fully charged turns on. (the one with the battery icon and the one with the connector icon i believe your laptop has them right below the track pad)do they turn on at all when you plug in your charger? if not then the problem is either the charger or the charger port on your laptop.— — — — — —Upgrading Computer?You should upgrade your RAM to at least 1GB, depending on what type of games you want to play you may soon find that 2GB is a better option. Expect to pay close to $200 for that much RAM though. A PCI Express x16 graphics card would work just fine for your machine. You have a ton of options here so try to find one that fits your budget. ASUS, EVGA, BFG are all good card manufacturers. If you wanted to go a step farther, you could also upgrade your processor to the 4000. This may give you a boost in speed and the chip is pretty reasonable at around $60. If you have never worked on a computer before, search online for some times prior to opening the case. You can destroy your system if you arent careful.
What Are the Functions of 245, 138, 4953, 5024 and Other Chips in LED Display
The functions of chips such as 24513849535024 in LED display screen are as follows:245 is used to control transceiver for input and output. Enhance the output driving ability of single chip microcomputer.138 is decoded, which can save ports. Because there are many pins used in the LED display screen, it can't be connected without decoding.The function of the 4953 is the line drive tube and the power tube. The current required for each display line is relatively large. To use the line drive tube, each 4953 can drive two display lines. 5024 is a 16 bit constant current LED driver, which can realize serial input and parallel output, and maintain the output current of each output pin 3-45ma.The output terminal withstand voltage is 17V, and multiple LEDs can be connected in series at each output terminal. The special driver chip for LED display screen refers to the driver chip specially designed for LED display screen according to the luminous characteristics of LED.The schematic diagram is as follows:The performance of driving IC determines the effect of LED display screen broadcasting, especially in the application of Maipu Guangcai small spacing LED display screen. In order to ensure the comfort of users using their eyes for a long time, low brightness and high ash have become a particularly important standard to test the performance of driving IC, making people's requirements for LED display screen driving IC more stringent. The LED display driving IC makes more effective use of the light board space of micro led ultra-small spacing display, and the high integration function can effectively reduce the cloth space and the number of components;In addition, in terms of picture quality performance, low brightness and high stability have always been the key to dominate viewing distance and display effect. The average constant current drive of a single color can be as low as 15ua, and the gray level level can reach 16bit, which makes the contrast and uniformity of the display picture more delicate, and can also achieve the effect of energy saving and low power consumption.Extended data:LED driver chips can be divided into general chips and special chips. The so-called general-purpose chip itself is not specially designed for LED, but some logic chips with some logic functions of Maipu brilliant LED display screen (such as serial parallel shift register). The special chip refers to the driver chip specially designed for LED display screen according to the luminous characteristics of LED. LED is a current characteristic device, that is, on the premise of saturated conduction, its brightness changes with the change of current, rather than by adjusting the voltage at both ends. Therefore, one of the characteristics of special chip is to provide constant current source.Constant current source can ensure the stable driving of LED and eliminate the flicker of LED. It is the premise for LED display to display high-quality pictures. Some special chips also add some special functions according to the requirements of different industries, such as brightness adjustment, error detection and so on.fqj
