The multilayer dielectric thin film can be part

With the Ceiling Panel Lights Suppliers related materials continue to emerge, the application of sophisticated equipment and application of new technology, optical coating technology is bound to inject new vitality for the development of light industry.

Optical barium titanate coating has become more widely used in electric light. Considering factors such as economy and efficiency, the industrialized and market-oriented applications of multilayer dielectric films and even electric light sources requires further research and development.mhcocm.

The single-layer dielectric film to selectively increase the reflectivity, but to further improve reflectivity in relation to use of multilayer dielectric. The greater the difference between two thin film of refractive index, the better the multi-layer dielectric film is mainly used in: the incandescent light bulbs, lamps (incandescent, halogen) is still the main light source of indoor lighting, the efficiency is very low. Colored foam dielectric film technology to produce more than 2*4 panel company the color of colored glass or enamel, luminous efficiency is also higher.

Department of TiO2 monolayer high visible light transmittance. The multilayer dielectric thin film can be part of the infrared reflection back to the filament, re-heating the filament in order to reduce power consumption to maintain the filament temperature required to improve the luminous efficiency to save energy. But for the present, it is still in its infancy.

Typical applications for fluorescent directional lighting, using TiO2 coated fluorescent tube to change its original radial symmetric light distribution, in order to achieve the purpose of directional lighting, such as reflective fluorescent aperture-type fluorescent lamps. Ultraviolet radiation, the internal hole diffusion to the surface hydroxyl adsorbed on the surface play a role in the formation of the active high hydroxyl gene, can be decomposed its surface adhesion of organic compounds, dust particles, at the same time play a sterilization effect.

In the electric light, the monolayer system is used in low pressure sodium lamps earlier. The film can infrared radiation is reflected back into the tube, and through the visible light. In addition to the inner cylinder and outer blister drawn into a magnesia vacuum to prevent convective heat loss, but also by chemical spraying outside the bubble wall is coated with indium oxide doped with tin film. The technology can be used in colored light bulbs, the production of the mosquito lamp. This light is widely used in film and television, food refrigeration, museums and other areas of lighting in colored interference film can reduce the thermal radiation of the illuminated object to remove infrared light bulbs or lamps
