How Does A Light Guide Work?
Mar 07, 2023
The ultra-thin light box of the light guide plate is a new type of advertising carrier developed by the inspiration of LCD TVs and drawing lessons from the backlight technology of LCD TVs (currently the industry calls it "ultra-thin light box", but I think it is not a light box. "Illuminated billboard" is more appropriate), its characteristics are as follows:
1. Ultra-thin and ultra-light: Beautiful appearance, its thickness is generally less than 3 cm, which maximizes the utilization of space, beautifies the environment, and broadens the scope of application.
2. Bright and uniform light: The bright light output is completely flat, and it is almost perfectly uniform, completely eliminating the bright and dark light marks common to ordinary light boxes. In addition to being widely used in public places, its excellent optical properties have expanded its application in high-tech fields such as precision display, photography and medical viewing, scientific research, and high-standard lighting. The effect is comparable to that of liquid crystal displays.
3. High efficiency and energy saving: Another commendable advantage of it is energy saving. Due to the use of advanced light guide plate lighting technology, the power consumption is only 23% of that of ordinary light boxes with the same screen area. Calculated on the basis of 10 hours of electricity consumption per day for a light box with a screen area of 1M2, the annual power consumption of ordinary light boxes is nearly 900 kWh, while that of ultra-thin light boxes is only 200 kWh, saving 77% of electricity.
4. Stable and durable: The special high-brightness and high-quality fluorescent tubes used in the ultra-thin light box have an average service life of more than 8,000 hours; The service life of the lamp tube used in the ultra-thin light box is 5 to 10 times of the service life of the ordinary lamp tube. The extended service life greatly saves maintenance costs.
5. Easy installation: The ultra-thin light box widely adopts the imported high-quality aluminum alloy open-type overall frame structure, equipped with movable hooks or hanging holes, which makes the installation of the light box and the replacement of the screen simple and fast, saving labor, time and money. money. Compared with the traditional light box, the ultra-thin light box will not happen: the light tube flickers, the brightness of the light tube is uneven, the light is dazzling, the outdoor light box is short-circuited and caught fire after entering the water, and the whole plane does not heat up, and the displayed light will not be yellowed by heat. .Ultra-thin light box uses liquid crystal light guide technology, which has higher brightness and strong integrity, so that the light of the picture is even and soft, and has a strong three-dimensional effect. Its novelty and fashion can bring better advertising effects and enhance your company image. Add points.
Ultra-thin light box principle: The main technology of the ultra-thin light box is the light guide plate. Simply put, it is to use a material with high reflectivity and non-absorbing light on the optical grade acrylic (plexiglass) plate, and use a laser engraving machine to mark the bottom of the light guide plate. Circular or square diffusion point, when the light hits the diffusion point from the side, the reflected light will diffuse to all angles, and then destroy the reflection condition and shoot out from the front of the light guide plate. Make the light guide plate emit light evenly, convert the side light emission into "surface" light emission, and add a reflector to reflect the light exposed on the bottom surface back into the light guide plate to improve the use efficiency of light.
