LED full colour wall screen

LED full colour wall screen

The LED (Light Emitting Diode) is a kind of can convert electric power into visible Light, because the semiconductor is easy to be control, the low voltage dc drives, combined colour performance rich, long life and other advantages, is widely used in designs city-lighting project, big screen display system. The LED display curtain wall, can as indoor under computer control color changes 10000, fully embodies the characteristics of high grade DISCO bar.

The LED colour wall screen, with DuoGe LED tube light emitting diode together display unit, through the power and control part of the programming, can produce DuoZhong color and the change of the light and dark, can fully satisfy some combination of the entertainment and a special lighting effect of the place requirement, can be widely used in DISCO bar, high-grade entertainment such as ballroom.

1. The benefits of using LED

The LED is a kind of can convert electric power into the visible semiconductor. Its features:
(1) the high efficiency, energy consumption is small.
(2) the light quality is good. Because no ultraviolet and infrared spectrum, so no heat, no radiation, LED to belong to typical green lighting source.
(3) the long life. Flux to 50% of the nominal attenuation life 100000 hours.
(4) use safety. Monomer working voltage in roughly 1.5 V ~ 5 V, work between current in about 20 mA.
(5) green environmental protection. Waste recycling, no pollution; Don't like fluorescent contain mercury composition.
6 flexible control. By adjusting the current can be light, different light color combination can be toning, plus sequential control circuit can achieve the dynamic changes of the diverse effect.

Above these advantages that LED to be considered as a kind of ideal green light source, is getting more and more successful application in engineering lighting and display field. The performance of the color in LED tube lighting control ability, ability, environmental protection, energy saving, and link than the traditional neon lights, incandescent lamp, halogen such as tungsten lamp has obvious advantages. The LED pixel can form the dynamic combination can be put visual effect.

2 green (G) LED high-brightness LED 525 nm
3 blue (B) LED high-brightness LED 470 nm

2. The main problems need to be solved

At present, in the light of the DISCO bar and control system, such as variety to construct a shock of full-color led panel as environment background light source, metope should be preferred option LED instead of the traditional power consumption, high, service life difficult control is not long, system safety coefficient of thermal radiation is a bit poor light source and gas discharge light source.
Design concept: environment background design is novel, the environmental protection, under computer control 10000 color change and reflects the DISCO bar high grade of characteristics. Through the whole point control, cascade data transmission, real-time response, up to the system LED tube lights unified whole bar internal control, adjust the corresponding tonal (such as the change of the show simple pictures) and the effect of atmosphere.

3. Design ideas

Sc-reens curtain wall shows involves, optical, electrical, and control, machinery, material, and art science technology. In guarantee under the premise of lighting function design to conform with the environment of the visual effect.

The specific design can use the luminous (show) square unit, and shine (show) unit consists of several LED, that is, in the square of milky within a protective covering PC, some LED the circuit boards of welding. A such a square "bulb" pixel unit according to certain matrix arrangement and through the positioning card ring, screws and other fixed in fire prevention board, and the fire prevention board installed in the metope formed a kind of square bulb, plus video link sc-reens curtain wall controller or computer constitute a structure simple color wall led display system. The whole color wall screen system can be through the whole point control, cascade data transmission, real-time response system, to achieve internal LED tube light to the overall unity and the adjustable control the corresponding tonal (such as show simple changes the picture) and the effect of atmosphere
