compares and analyzes the effects of light diffusion among 3 types of LED tubes: PC cover, glass tube, and glass-PET, reveals their features, advantages, and disadvantages. The light transmittance of both organic and inorganic light diffusion materials were investigated and discussed
The performance and characteristics of polytetrafluoroethylene, the common methods of modi- fying polytetrafluoroethylene and polymer alloys, and the application of polytetrafluoroethylene in the fields of electronics, electrical, medical and environmental protection are introduced.
Polycarbonate(PC) was used as matrix material，acrylic and organosilicone resins were used as light diffusing agents，the effect of the type，contents and particle size of light scattering agents on the mechanical properties，transmittance and haze of light diffusing materials based on PC were studied.
Through the performance difference analysis of various water soluble lm former resin in the process of trial production and application results of various light diffusion additives in coating, selection and application researches of the lm formers resin and light diffusion additives are carried out on light diffusion coating of the linear glass tube LED lamp .
Silicone resin powder is also suitable for high-end anti-adhesive film with high transparency and shedding resistance, which can be produced by two-way stretching method.
Introduce the principle of light scattering，the production method，the test method of haze value，the influence of the film on the light intensity，the temperature and the application effect of the film are introduced.
