the purpose of the light guide panel and the price of the light guide panel
Jul 28, 2021
The design principle of the light guide plate is inspired by the LCD display of the notebook computer, using the LCD display and the notebook computer backlight module technology, the light transmission rate through the light guide point is ultra-thin, ultra-bright, uniform light guide, energy saving, environmental protection, No dark area, durable, not easy to yellow, easy to install and maintain. Next, let's learn about the application and price of the duct plate.
Application of light guide plate
1. The appearance is beautiful, the thickness is basically less than 3 cm, and the space utilization rate is greatly improved, the environment is beautified, and the application range is broadened.
2. The bright light feeling is completely flat output, which completely eliminates the light and dark light feeling common to ordinary light boxes. Wide range of applications in public places, while expanding its precision display, photography and medical viewing, scientific research, high-standard lighting, applied to high-tech technical fields.
3. There is another energy saving, using advanced light-guide plate luminescence technology, the power consumption is 23% of that of the ordinary light box with the same screen area. The annual power consumption of ordinary light boxes is 900 kWh, while the annual power consumption of ultra-thin light boxes is only 200 kWh, which saves 77% of electricity.
4. The special high-brightness fluorescent tube used in the ultra-thin light box has a service life of 8,000 hours; the average service life of the dedicated cold cathode lamp 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 that of the ordinary lamp tube.
Light guide plate price
The price of light guide plate is one of the main costs of light guide plate related products. With the development of surface light source products, the market demand for light guide plate is increasing. However, the price of light guide plate on the market varies greatly, which really makes many buyers a headache. . Here, taking the printed light guide plate as an example, analyze the main factors that constitute the price of the light guide plate:
1. The base material of the light guide plate is the main factor in the price of the light guide plate: Generally speaking, the market light guide plate mainly uses the following materials, PS, PC, PMMA three materials have a large price difference. Of course, due to the characteristics of the respective materials, The optical characteristics of the corresponding light guide plate, especially the light transmittance of the whole line, are also quite different. In addition, due to the production of physical characteristics, there are differences in weather resistance, anti-ultraviolet characteristics and so on.
2. Light guide plate printing ink is another important factor in the price of light guide plate: there are two types of light guide plate inks: domestic and imported. Compared with imported inks, domestic inks have ink adhesion and light emission after forming optical dots. , The refractive index and other aspects have obvious shortcomings.
3. The cutting method of the light guide plate is also an influencing factor of the price of the light guide plate: the common light guide plate on the market is simple laser cutting, which is simple and low cost, but there are obvious traces of laser melting on the edge of the light guide plate. This will affect the full-line entrance of the side light to a certain extent. Corresponding to this is another diamond cutting machine on the market. The edge of the light guide plate processed by this processing method is smooth and friendly to light.
In summary, the above three factors each affect the performance of the light guide plate to a certain extent, and are also the main factors that determine the price of the light guide plate. However, from the perspective of cost performance, we recommend that PMMA material and imported ink printing should be considered at least for the popular LED flat light guide plates on the market.
