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.
