Full reflection type illumination device

Abstract

The invention relates to a full reflection lighting device which comprises a cover of the lighting device, a light transmission film, a light transmission channel and a light source, and is characterized in that: the surface of the light transmission film is coated with titanium dioxide nanometer collosol to form a layer of titanium dioxide film, the thickness of which is less than 1000nm. An insulating energy-saving material is arranged between the light source and an opening of a light inlet of one end of the cover of the lighting device. Alternatively, a condensing convex lens can be arranged in front of the Insulating energy-saving material or the condensing convex lens is arranged in the back of the Insulating energy-saving material so as to increase luminous flux of an incident light source. The invention is a lighting design which can realize energy saving and utilize clean energy sources, uses the light transmission film, the surface of which is coated with high refraction index titanium dioxide to transmit light emitted by light sources such as the sun or artificial light sources and so on, and performs lighting in full reflection transmission means with high effectiveness.

Description

technical field [0001] The invention relates to a total reflection lighting device, in particular to a lighting device that can realize energy saving and utilize clean energy. Membrane for lighting with high-efficiency total reflection transfer. Background technique [0002] Light-conducting film technology is a technology for transmitting light. Its principle is to paste a layer of total reflection film on the inner wall of a hollow pipe, and transmit the light emitted by the light source from one end to the other end through total reflection in the pipe. To achieve the role of lighting. If the characteristics of the light-conducting film are effectively used, the lighting system can use the sunlight during the day to effectively transmit to dark indoor rooms or rooms that are flammable, explosive, and unsuitable for electric light sources, which can effectively reduce power consumption and improve many lighting conditions. safety of the place. Light-conducting film tech...

AI Technical Summary

Problems solved by technology

Although this patent is simpler in structure than US Patent 6141645, its ventilation and lighting share a channel, so that the dust in the air will be deposited on the surface of the optical film, affecting the light transmission efficiency

[0005] Although the light guide has a good efficiency for light transmission, in practical applications, the incident angle of light and the angle of light control must be less than 36°, and the light-conducting film is made of plastic material, which is a disadvantage for dust adhesion. After the dust adheres, it will seriously affect the light transmission efficiency. The above problems have not yet been solved.
