The decorative effect of the PC board is amazing!

 As early as the end of the 20th century, the concept of light dispersion materials was proposed. Light dispersing materials refer to materials that can not only pass light through but also effectively scatter light. It can convert point light sources into line light sources or convert line light sources into surface light sources, and can be used as surface light source materials for cold light sheets, guides, etc. Light panels, backlight devices and liquid crystal displays and other equipment.

This is because the light dispersant in the light dispersing material is evenly distributed. When the point light source of the LED passes through the light dispersing material, it will produce many refraction, reflection, scattering and other phenomena when encountering dispersant particles and media with different refractive indices. Make the light evenly pass through the material without exposing the lamp beads, achieve the uniform transformation from point light source to surface light source, and obtain the effect of optical dispersion.

Polycarbonate sheet is widely used to process LED lampshades and light-dispersing sheets because of its excellent mechanical properties, such as aging resistance, no cracking, and high heat distortion temperature. The material used in the lighting project is a new type of green petroleum derivative - PC board. The PC board is processed into "oil and gas pipelines", which are crisscrossed and "woven" to form the building shell, and then the specially distributed LED point light sources are hidden in the PC shell. Inside, the PC shell is evenly illuminated by means of internal light and external transmission, forming a beautiful special effect, and any colorful video image can be displayed through the control system. The number of LED point light sources in the lighting project of the Shanghai World Expo Petroleum Pavilion, the use of PC boards as the light receiving carrier to realize the video display method of internal light and external transmission, and the screen layout have all created the world's first.

The huge oval LED display wall in the London Museum uses transparent PC tubes as the protective lampshade for the LED units. The transparent material is a polycarbonate material produced in line with the development trend. Its unique weather resistance such as ultraviolet resistance makes it widely used in the optical field. The lampshade made of this material for the LED display wall of the London Museum has high light transmittance, which can ensure that the light is effectively concentrated and directional.

However, although the traditional optical-grade PC Sheet has a certain dispersion power for point light sources, it is far from meeting the growing demand for its use in the LED field. Therefore, light dispersion materials based on PC sheets have gradually entered the market. The stage of the new material.

Light dispersing PC board is obtained by uniformly dispersing light dispersant in Plastic Sheet. It has excellent light dispersion, light transmittance and outstanding UV stability, and is widely used in the LED industry.

The principle of light dispersion is: when the light hits the surface of the light-dispersing PC sheet, because the refractive index of the PC resin and the light-dispersing agent are different, the light is reflected like a mirror on the surface of the light-dispersing agent, and after repeated reflections, the light-dispersing effect is achieved. At present, light-dispersing PC sheets have attracted extensive attention from scientists at home and abroad, and have already been used commercially. Some famous companies have developed related products and won a wider market.
