LED color screen that LED color screen is what we often say LED display, LED color screen is the application of LED technology to the field of outdoor decorative lighting, its working principle is composed of two parts driven and controlled, with small LED square lamp as The light emitting display unit is formed by connecting a plurality of square LED lamp pixel units in accordance with a certain matrix to form an LED screen or an LED billboard, plus a video controller. So, what are the advantages of LED color screens and the problems to be solved?
According to experts from Henan Mingxinyuan Technology Co., Ltd., LED is a semiconductor that can convert electrical energy into visible light. It is widely used due to its advantages of easy control, low voltage DC drive, rich color performance after combination, and long service life. City lighting project, large screen display system.
1. Benefits of using LEDs LEDs are semiconductors that convert electrical energy into visible light. Its characteristics are:
(1) Environmental protection, waste can be recycled, no pollution, unlike fluorescent lamps containing mercury.
(2) The control is flexible, and the light can be adjusted by adjusting the current. The combination of different light colors can be used for color correction, and the timing control circuit can achieve various dynamic changes.
(3) The light quality is good. Because there is no ultraviolet and infrared rays in the spectrum, there is no heat and no radiation. The LED is a typical green lighting source.
(4) The use of safety, single operating voltage is generally between 1.5V ~ 5V, working current is about 20mA.
(5) High efficiency and low energy consumption.
(6) Long life, luminous flux decay to 50% of the nominal life of 100,000 hours.
2. Problems to be solved At present, there are a large variety of lighting and control systems in the DISCO bar. If you want to construct a shocking full-color display wall as an environmental background, the light source should give priority to the selection of LEDs rather than the traditional large power consumption. Thermal radiation sources and gas discharge light sources with high control difficulty, short service life and slightly poor system safety.
Design concept: The environment background is novel in design, environmental protection, and computer-controlled color changes, reflecting the characteristics of the high-grade DISCO bar. Through the overall point-by-point control, cascaded data transmission, and instant response of the system, the overall unified control of the LED lighting inside the bar is achieved, and the corresponding hue (such as displaying a simple changing picture) and atmosphere are adjusted.
3, design thinking LED display screen display involves optical, electrical, control, machinery, materials, art and other multi-disciplinary technology. Under the premise of guaranteeing the lighting function, the design achieves the visual effect that matches the environment.
The specific design can use a square light emitting (display) unit, and the light emitting (display) unit is composed of a plurality of LEDs, that is, in a square milky white PC protective cover, a circuit board that solders several LEDs. Such a square “bulb†pixel unit is fixed on a fireproof board by positioning a snap ring, screws, etc. in accordance with a certain matrix arrangement. The fire board is installed on the wall to form a square bulb LED screen wall, plus a connection. The video controller or the computer constitutes a simple color wall screen display system. The entire color wall screen display system can achieve overall unified control of the LED lighting inside the bar through overall point-by-point control, cascaded data transmission, and instant response of the system, and adjust the corresponding hue (such as displaying a simple change of picture) and atmosphere effect.
