In recent years, with the rapid development of the LED lighting industry, the use of LED lamp housing materials has also increased rapidly. The outer casing material for LED illumination, that is, the light-scattering material, refers to a material that can pass light and efficiently scatter light. It can convert electric and line light sources into line and surface light sources.
The high brightness and low heat of LEDs save electricity consumption and meet the pursuit of low carbon and environmental protection. However, the light emitted by the LED is a directional light, which is a point source. The disadvantage is that the light is glaring, the eye is difficult to accept, and the illumination area is small. If you use it as a lighting, you must scatter the light to achieve the lighting effect. The appearance of polycarbonate light spreading materials with high light transmittance, high diffusion, and uniform light has solved this problem well.
The so-called light-diffusing engineering plastics refer to a kind of light-transmitting and opaque light-diffusing material particles which are formed by transparent polycarbonate engineering plastics as a substrate and added with a certain ratio of light diffusing agents and other auxiliary agents through a special process.
The polycarbonate light diffusing material is formed by adding a light diffusing agent to the engineering plastic to form a specular reflection on the surface of the light diffusing agent, and after multiple reflections, the light diffusing effect is achieved. It is a material for converting a point and a line source into a line and a surface light source, and is generally prepared by dispersing light diffusion particles having different refractive indices from a substrate in a transparent substrate.
Due to the special structure of polycarbonate, it has become the fastest growing general engineering plastic among the five engineering plastics. Nowadays, the application of polycarbonate is developing in the direction of high compounding, high function, specialization and serialization. It is found in many fields such as automobiles, electronics, medical, and packaging. Among them, the LED lighting field has also become another very important application field of polycarbonate in recent years, and in a few short years, it has achieved very rapid development. The experimental results show that the use of polycarbonate LED shades can better concentrate the light and make the light more concentrated.
With the birth of new materials and new technical support, people have embraced a new era of LED light. LED power consumption is quite low, and the same lighting effect is nearly 80% more energy efficient than traditional light sources. In addition, LEDs, etc., have changed the lighting facilities of many industrial industries due to their light weight and strong surface resistance. Car lights are a very remarkable example. In the past, most of the headlights of automobile lamps were made of glass. Today, polycarbonate replaces traditional glass, which can reduce the weight by half, thus greatly reducing the energy consumption required for driving internal combustion engine vehicles, thereby greatly reducing carbon dioxide emissions. The weight reduction also makes the next generation of hybrid and electric vehicles possible, because the increased weight of the battery requires the chassis to reduce the same weight to balance to avoid vehicle efficiency and performance degradation.
The transformation of a small LED shade material has pushed the lightweight process of the automotive industry. The polycarbonate light spreading material not only solves the problem of strong light source rays of LED lamps, but also contributes to the sustainable development of human beings. At the same time, it also contributes to energy conservation and environmental protection and promotes industrial upgrading in the corresponding “Twelfth Five-Year Plan” of the country. Call.
