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.

Embodiment 1

[0032] Such as figure 1 As shown, the total reflection illuminating device of the present invention comprises an illuminating device housing 1 that is an opaque stainless steel tube, and a light-conducting film 2 that is attached to the inner edge of the stainless steel tube, and the titanium dioxide sol is coated on the inside of the light-conducting film by a roll coating method. The formed titanium dioxide sol thin film 3 has a coating thickness of 50 nm, forming a light transmission space 4 in the stainless steel tube, a light source 5 and a light transmission direction 6 to form a complete light transmission lighting device. The light source used in the lighting device of the present invention is sunlight, and the outdoor sunlight is transmitted to the room through a light-conducting film to realize natural lighting. The light intensity measured at the entrance of the light transmission tube is 87400 lux, and the light intensity is 87400 lux through the 15m long light tran...

Embodiment 2

[0034] Such as figure 1As shown, the total reflection lighting device of the present invention comprises a lighting device housing 1 which is a light-transmitting plastic tube, and a light-conducting film 2 attached to the inner edge of the plastic tube, and the titanium dioxide sol is applied to the light-conducting film by a brushing method. The titanium dioxide sol thin film 3 formed on the inside has a coating thickness of 380nm, forming a light transmission space 4 in the plastic tube, a light source 5 and a light transmission direction 6 to form a complete light transmission lighting device. The light source used in the lighting device of the present invention is sunlight, and the outdoor sunlight is transmitted to the room through a light-conducting film to realize natural lighting. The average illuminance measured on the surface is 8350lux, and the illuminance difference between the front end and the end of the light transmission tube is within 10%. Using the principle...

Embodiment 3

[0036] Such as figure 1 As shown, the implementation process is similar to Example 1, except that the light source 5 adopts an artificial light source and the thickness of the titanium dioxide coating is 740nm, and the light intensity measured at the entrance of the light transmission tube is 53630lux, through the 10m long light transmission tube, in the tube The light exit at the other end is 50670lux, with a light transmission efficiency of more than 94%, using the principle of total internal reflection, such as figure 2 As shown, a lighting system that transmits artificial light sources to a distant place can be realized.

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...
