LED is a semiconductor that can convert electrical energy into visible light. Because of its easy control, low-voltage DC drive, rich color performance after combination, and long service life, it is widely used in urban lighting projects and large-screen display systems. The led color wall screen is a new product applied to the field of outdoor decorative lighting with led technology. Its working principle is composed of two parts: drive and control. Small led square lights are used as light-emitting display units, and multiple square led pixel units follow a certain LED screen or LED advertising billboard is formed by arraying in a matrix, which is connected with a video controller and a computer.
Because it can produce light, shade and color changes according to melody and rhythm, and can form various dynamic picture effects, it can set off a kind of dreamy blurred, dazzling mysterious, gorgeous lanthanum background lighting, which corresponds to the high-end DISCO bar, The special requirements of entertainment venues such as song and dance halls on the lighting background make the expression of indoor lighting more abundant and optimized. Through overall point-by-point control, cascaded data transmission, and system real-time response, the overall unified control of LED lighting in entertainment venues such as KTV, restaurants, dance halls, and karaoke halls is achieved, forming a more harmonious overall effect.
One, design thinking
The led display involves multi-disciplinary technologies such as electricity, control, optics, machinery, materials, and art. Under the premise of ensuring the lighting function, the design achieves a visual effect consistent with the environment.
The specific design can use a square light-emitting (display) unit. The light-emitting (display) unit is composed of a number of LEDs, that is, a circuit board on which a number of LEDs are welded are installed in a square milky white PC protective cover. Such a square "bulb" pixel unit is arranged in a certain matrix and fixed on the fireproof wooden board by positioning snap rings, screws, etc. The fireproof wooden board is installed on the wall to form a square light bulb led screen wall, plus connection The video controller or computer constitutes a simple color wall screen display system. The entire color wall screen display system can achieve a unified control of the LED lighting inside the bar through the overall point-by-point control, cascaded data transmission, and instant response of the system, and adjust the corresponding color tone (such as displaying a simple changing picture) and atmosphere effect.
Second, the benefits of using leds
Led is a semiconductor that can convert electrical energy into visible light. Its characteristics are:
1. High efficiency and low energy consumption.
2. The light quality is good. Since there is no ultraviolet and infrared in the spectrum, there is no heat and no radiation. LED is a typical green lighting source.
3. Long life, 100,000 hours of nominal life with luminous flux attenuated to 50%.
4. It is safe to use, the working voltage of the single unit is roughly between 1.5V and 5V, and the working current is around 20mA.
5. Green and environmental protection, waste can be recycled, no pollution; unlike fluorescent lamps that contain mercury.
6. Flexible control. The light can be dimmed by adjusting the current, and the combination of different light colors can be adjusted. With the timing control circuit, various dynamic changes can be achieved.
These advantages make LEDs considered as an ideal green light source, and it has been increasingly successfully applied in the field of engineering lighting and display. LED has obvious advantages over traditional neon lights, incandescent lamps, halogen lamps, etc. in terms of color performance, light control ability, environmental protection and energy saving. The combination of led pixels can constitute dynamic and ever-changing visual effects.
Three problems to be solved
There are many kinds of lighting and control systems in the DISCO bar. If you want to construct a shocking full-color display wall as the environmental background, the light source should be given priority to LED instead of the traditional high power consumption, high control difficulty, and short service life. , Thermal radiation light source and gas discharge light source with poor system safety factor.
Design concept: The environmental background design is novel, environmentally friendly, and the colors change under the control of the computer, reflecting the characteristics of the high-grade DISCO bar. Through overall point-by-point control, cascaded data transmission, and real-time response of the system, the overall control of the LED lighting inside the bar is achieved, and the corresponding color tone can be adjusted.
