The PC light diffusion lampshade is made by adding a light diffusion agent to the PC resin. The light diffusion agent is spherical and uniformly dispersed in the PC resin to form an island structure. Because the refractive index of the pc light diffusion lampshade resin and the light diffusion agent are different, the light is in the pc light The surface of the diffuser lampshade agent is similar to mirror reflection, and after multiple reflections, the light diffusion effect is achieved.The addition amount, particle size and distribution, and refractive index of the pc light diffuser lampshade agent determine the optical properties of the material. The optical performance indicators of the light diffusion material include Total light transmittance, haze, and dispersion. The dispersion refers to the angle at which the relative light transmittance is 50%. How to achieve high light transmittance and high haze of astigmatic materials is a difficult point. The light direction of fluorescent lamps Surroundings, the light irradiated from the back reflects and then returns to the front. If the light in the front exceeds the critical angle, it will be reflected. Such light will go through a variety of reflection processes to reach the front again. Other light from the diffuser will be refracted and enter the interior of the diffuser. After entering the diffuser, it encounters the diffuser, performs multiple reflections and astigmatism, and maintains a certain brightness on the surface during this process.
Features of pc light diffusion lampshade:
1. The light transmittance of the pc light diffusion lampshade endurance board is 65%, while the light transmittance of the general-purpose pc light diffusion lampshade milky endurance board is only 20%. So in
Used in the advertising light box industry, the advertising effect is more realistic.
2. The general-purpose pc light diffusion lampshade milky board can penetrate the LED lamp source, and the pc light diffusion lampshade endurance board can fully diffuse the LED lamp source traditional fluorescent lamp.
Because of the large power consumption and high operating cost), after switching to LED light source and light diffuser, it can save more than 80% of the electricity bill.
The economic benefits are significant.
3. The impact resistance of pc light diffusion lampshade is 20-30 times that of acrylic sheet, and it is not easy to be damaged during installation and transportation.
4. The flame retardant grade is higher than that of the acrylic sheet, reaching the flame retardant B2 level, and the safety performance is higher.
5. The temperature resistance of pc light diffusion lampshade is -40℃-+120℃ and will not deform due to the long-term irradiation of the lamp source.
