The LED is a way to convert electrical energy into visible light by semiconductor, as it’s easy to control, low-voltage DC drivers, the combination of rich color performance, long life, etc., led products are widely used in city lighting projects, large screen display system. LED color wall screen is LED technology is applied in the fields of outdoor decorative lighting, new products, and its working principle is to drive and control two parts, the square with small LED lights as a light-emitting display unit, according to a certain pixel unit by the number of square LED lights matrix of the formation of the LED (t5 led lighting) screen or LED billboards, plus connect video controller and computer form.
LED is a way to convert electrical energy into visible light by semiconductor. Its characteristics are:
a. high efficiency, low energy consumption.
b. The light quality is good, no ultraviolet and infrared spectra, and there is no heat, no radiation, the LED is a typical green lighting.
c. long life, luminous flux to decay to 50% of the nominal life of 100,000 hours.
d. security. Monomer voltage roughly between 1.5V ~ 5V, the current is about 20mA.
e. green. Recyclable waste, no pollution; unlike fluorescent lamps contain mercury components.
f. flexible control by adjusting the current dimming, a combination of different colors of light can be color, coupled with the timing control circuit can achieve a variety of dynamic changes.
These advantages make the LED (t5 led lighting) is considered to be an ideal green light, has become increasingly multi successfully applied in the field of engineering lighting and display. The performance of the LED tubes in the color, lighting control, environmental protection and energy saving aspects of, than traditional neon, incandescent, halogen, has obvious advantages. LED pixel combinations can form a dynamic, ever-changing visual effects.
The specific design of square light-emitting (display) unit, light-emitting (display) unit consists of a number of LED (t5 led lighting) square milky PC protection cover, equipped with welding a number of the LED circuit board. A square “light bulb” pixel unit in accordance with the matrix arrangement by positioning snap ring, screws and other fixed fire wood on the fire wood is installed in the wall constitutes a square bulb LED video walls, plus connect video controller or a computer constitutes a simple structure of the wall color screen screen display system. The wall color screen display system controlled by the overall point by point, cascade data transfer, the system is an immediate response, to achieve the overall centralized control of the bar internal LED lights, and adjust the corresponding colors (for example, shows a simple change of the screen) and the atmosphere effect.
