LED (Light Emitting Diode) is a kind of semiconductor capable of converting electric energy into visible light. It is widely used in urban lighting engineering, large screen display because it has the advantages of easy control, low voltage DC drive, rich color performance after combination, long service life System. LED can be used as indoor display curtain wall, under the control of the computer color change thousands, fully embodies the characteristics of high-grade DISCO bar.
LED color wall, with a number of LED light-emitting diode combination of the display unit, through the power and control part of the programming, can produce a variety of colors and bright and dark changes in the combination, can fully meet some of the entertainment and special lighting effects of the place Requirements, can be widely used in DISCO bars, high-end dance halls and other entertainment.
1. The benefits of using LED
The same time as
LED is a semiconductor capable of converting electrical energy into visible light. Its characteristics are:
① high efficiency, low energy consumption.
② good light quality. As the spectrum is not ultraviolet and infrared, so there is no heat, no radiation, LED is a typical green lighting source.
③ long life Luminous flux decay to 50% of the nominal life of 100,000 hours.
④ use of security. Single working voltage roughly between 1.5V ~ 5V, the working current of about 20mA.
⑤ green. Waste can be recycled, no pollution; unlike fluorescent lamps contain mercury.
⑥ control flexible. By adjusting the current can be dimmed, the combination of different light color can be tinted, coupled with the timing control circuit can achieve a variety of dynamic changes.
These advantages make LED is considered an ideal green light source, has been more and more successfully applied in the field of engineering lighting and display. LED in the color of the performance capacity, lighting control, environmental protection and energy conservation and other aspects, than the traditional neon lights, incandescent, halogen lamps have obvious advantages. LED pixel combination can constitute a dynamic can be ever-changing visual effects.

2. The main problem to be solved
At present, DISCO bar lighting and control system variety, such as to build a shocking full-color display wall as the environment background, the light source should give priority to select the LED, rather than the traditional power consumption, control difficult, life Not long, the system safety factor slightly worse heat radiation and gas discharge light source.
Design concept: environmental background design novel, environmental protection, in the computer control color change thousands, reflecting the characteristics of high-grade DISCO bar. Through the overall point-by-point control, cascade data transmission, real-time response to the system, to achieve a unified control of the interior of the bar LED lights, adjust the corresponding tone (such as the display of simple changes) and the effect of the atmosphere.
3. Design ideas
Color display curtain wall display involves optical, electrical, control, machinery, materials, art and other multi-disciplinary technology. In the premise of ensuring the lighting function designed to meet the visual effects consistent with the environment.

The light-emitting (display) unit is made of a number of LEDs, that is, in a square-shaped milky white PC protective cover, with a circuit board for welding several LEDs. Such as a square "bulb" pixel unit in accordance with a certain matrix arrangement by positioning the ring, screws and other fixed on the fire board, the fire board installed on the wall to form a square light bulb color display wall, plus Connected to the video controller or computer to form a simple structure of the color wall display system. The entire color wall display system through the overall point by point control, cascade data transmission, the system real-time response, to achieve the overall control of the bar inside the LED lights unified control, and adjust the corresponding tone (such as the display of simple changes) and the atmosphere effect.
