Introduction of light guide sheet

The design principle of the light guide plate is derived from the LCD screen of a laptop computer, and it is a high-tech product that transforms a line light source into a surface light source. Optical grade acrylic (PMMA)/PC as the base material, using LCD display and notebook computer backlight module technology, through the high light conductivity of the light guide point, the computer calculates the light guide point, so that the light of the light guide plate is refracted into The surface light source is manufactured in a uniform light state. The product adopts the principle of spectrum analysis combined with digital UV printing technology and is manufactured under constant temperature, humidity and dust-free environmental conditions. It has the distinctive features of ultra-thin, ultra-bright, uniform light guide, energy saving, environmental protection, no dark area, durability, not easy to yellow, simple and quick installation and maintenance.

The light guide plate ultra-thin light box is inspired by the LCD TV and borrows the backlight technology of the LCD TV, and developed a new type of advertising carrier (the industry calls it "ultra-thin light box". I think it is not a light box, but called "luminous light box". "Advertising board" is more appropriate), and its features are as follows:

1. The appearance is beautiful, and its thickness is generally less than 3 cm, which maximizes the space utilization rate, beautifies the environment, and broadens the scope of application.

2. The bright light is completely flat output, and it is almost perfect and uniform, completely eliminating the light and dark light marks shared by ordinary light boxes. In addition to its excellent optical properties, it is widely used in public places, and it has also expanded its applications in high-tech fields such as precision display, photography and medical viewing, scientific research, and high-standard lighting. The effect is comparable to LCD displays.

3. Another commendable advantage is energy saving. Due to the use of advanced light-guide plate lighting technology, the power consumption is only 23% of the ordinary light box with the same screen area. Based on the 1M2 screen area light box using 10 hours of electricity per day, the annual power consumption of ordinary light boxes is nearly 900 kWh, and the annual power consumption of ultra-thin light boxes is only 200 kWh, which saves 77% of electricity. Only the electricity saved in the year can recover the investment.

4. The average service life of the special high-brightness and high-quality fluorescent tubes used in the ultra-thin light box is more than 8,000 hours; the average service life of the dedicated cold cathode lamps is more than 15,000 hours. The service life of the lamp tube used in the ultra-thin light box is 5 to 10 times the service life of the ordinary lamp tube. The extension of the service life greatly saves maintenance costs.

5. The ultra-thin light box widely adopts imported high-quality aluminum alloy open-type overall frame structure, equipped with movable hooks or hanging holes, so that the installation and screen replacement of the light box are simple, fast, labor-saving, time-saving and money-saving.
