The diffused PC material has the characteristics of high light transmission, high haze, V0 flame retardant, etc. It is generally used in LED lamp extruded tube, light diffuser, injection bulb for LED lamp, lampshade, etc.
The diffusion rate of the light diffusion pc can reach 99%, the dispersion is uniform without crystal points, the light transmittance can reach 86-93%, and the brightness is more than twice that of the traditional lampshade. 1. Introduction of the light diffusion pc:
Light diffusing pc is by adding a light diffusing agent to the pc resin. The light diffusing agent is spherical and uniformly dispersed in the pc resin to form an island structure. Because the refractive index of the pc resin and the light diffusing agent is different, the light on the surface of the light diffusing agent is similar to a mirror.
Surface reflection, after multiple reflections, the light diffusion effect is achieved. The amount of light diffusion agent added, particle size and distribution, and refractive index determine the optical properties of the material. The indicators for evaluating the optical properties of light diffusion materials include total light transmission
Rate, haze, dispersion. Among them, dispersion refers to the angle of relative light transmittance of 50%. How to achieve high light transmittance and high haze of astigmatism materials is a difficult point. The light of fluorescent lamps is irradiated around, from The light from the back is reflected and then returns to the front. If the light in the front exceeds the critical angle, it will be reflected. Such light will re-arrive to the front through a variety of reflection processes. The other light of the diffuser will be refracted to the inside of the diffuser. To the diffuser After the interior, it meets with the diffuser, performs multiple reflections and astigmatisms, and maintains a certain brightness on the surface during this process. The diffusion rate of the light diffusion pc can reach 99%, the dispersion is uniform without crystal points, and the light transmittance can reach 86- 93%, the brightness is more than 2 times that of traditional lampshades. Mainly divided into injection molding grade, extrusion grade, blow molding grade, film grade, frosted grade.
Second, the application of light diffusion plastics: led bulb lights, led fluorescent lights, led digital tubes, led tunnel lights, led street lights, led ceiling lights, etc.
Third, the characteristics of light diffusion plastic: high light transmission, high diffusion, no glare, no light and shadow optical grade pc raw material. .Aging resistance, good flame retardancy, good UV resistance. It can be extruded or injection molded, easy to use and low loss. The light source has excellent concealment and no light spot. Has high impact strength. Suitable for LED light bulbs, tubes, light-transmitting plates, shells, etc., special light-diffusing pc plastic for LED lighting lampshades. Edit the characteristics of light diffusion pc Light diffusion pc is by adding a light diffusion agent to the PC resin, the light is similar to a mirror reflection on the surface of the light diffusion agent, and after multiple reflections, the light diffusion effect is achieved. The diffusion rate of light diffusion pc can reach 99%, the dispersion is uniform without crystal points, the light transmittance can reach 86-93%, and the brightness is more than twice that of the traditional lampshade. Commonly used in led bulb lights, led fluorescent lights, led digital tubes, led tunnel lights, led street lights, led ceiling lights, etc.
