Abstract
An optically reflective plate used for air conditioner, refrigerator, etc is composed of a wedged reflecting plate made of transparent material and with smooth internal surface, and a light source installed at one side of said reflecting plate, which may be ultraviolet light source. Said reflecting plate has a thickness variable with the distance from light source and a concave point array on its back. The density of concave points varies with the distance from light source. The shading material is arranged on three side surfaces and the back of said reflecting plate. A photocatalytic disinfecting deodourizing unit is installed in the front of said reflecting plate.
Description
Technical field
The invention belongs to the optical reflection device, more particularly relate to the improvement of the regeneration of decoration, sterilization and photocatalyst with light guide reflecting board.
Background technology
There are following shortcoming and defect in existing decoration, sterilization with light guide plate, leaded light post or reverberator: leaded light, reflection efficiency are low, luminance shortage, the brightness irregularities of light guide plate, intensity of light reflection with the very fast decay of the distance of light source.Thereby decorative effect is relatively poor.When this light guide plate was used for the regeneration activating of uv disinfection or photocatalyst, low because of its leaded light efficient, decay is fast, the regeneration effect of sterilization or photocatalyst was also poor.
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of leaded light efficient height is provided, the brightness height, and the brightness of light guide plate is even, and intensity of light reflection is with slower with the range attenuation of light source; Thereby good decorating effect; When being used for the regeneration activating of uv disinfection or photocatalyst effect might as well light guide reflecting board.
Summary of the invention
In order to achieve the above object, the present invention is made up of smooth reflecting plate of the inside surface made from transparent material and near be installed in the reflecting plate electric light source.Reflecting plate is a wedge shape, that is between its backside reflection face and the front angle α is arranged, and the thickness of reflecting plate is with the distance of distance electric light source attenuate gradually, and electric light source is installed in a side of reflecting plate.The light that electric light source sent enters after the reflecting plate, through the repeatedly reflection of its three side perimeters and backside reflection face thereof, finally reflects from its front in reflecting plate, sees to be exactly a high brightness and luminous uniform refractive body from its front.One angle α is arranged between the backside reflection face of wedge shape reflecting plate and the front, and its size should just make most of incident light reach critical angle formation total reflection on the reflecting surface overleaf.Therefore, catoptrical intensity does not have decay substantially, keeps high brightness, and luminous even.
The back side of reflecting plate has the dot matrix concave point.Inner bulge under the outer concave of dot matrix concave point.The arranging density of the dot matrix concave point at the back side of reflecting plate increases with the increase of the distance of distance electric light source.At the light of reflecting plate internal reflection to the inner bulge face of dot matrix concave point, because of the curvature of concave point is very big, the surface forms diffuse reflection within it, thereby makes us more bright at these dot matrix concave points of seeing previously of reflecting plate.The arranging density of dot matrix concave point increases with the increase of the distance of distance electric light source, and further the compensatory reflex light intensity makes reflecting effect more even with the summary microwave attenuation that distance increases.
Except that the side that electric light source is installed, its excess-three side perimeters and backside reflection face thereof are provided with light screening material.Light screening material can be a kind of of plated film, aluminium foil, reflecting coating, light paper, light PVC etc., and its inside surface is a shiny surface.The light screening material that inside surface is very smooth forms desirable interior reflective surface, has avoided the diffuse reflection of light, has avoided scattering and disappearing and decay of light.
Electric light source is ultraviolet electric light source, and the front of reflecting plate is installed with the photo-catalytic sterilization deodoriser.Ultraviolet ray self has powerful bactericidal action, can play bactericidal action to using air conditioner of the present invention, refrigerator etc.In addition, photo-catalytic sterilization deodoriser before in use needs regularly to shine in the sun ability regeneration use in 4～6 hours.And use the air conditioner, refrigerator etc. of photo-catalytic sterilization deodoriser of the present invention, then can exempt this trouble.This structure of the present invention can be regenerated the photo-catalytic sterilization deodoriser voluntarily.
Electric light source can be monochrome or polychrome.The different color of electric light source can improve decorative effect of the present invention greatly.
Reflecting plate can be by material such as transparent plastics, glass.This type of material price is cheap, cost is low, and manufacture craft is also simpler.
Task of the present invention comes to this and finishes.
The invention provides a kind of leaded light efficient height, the brightness height, brightness is even, and intensity of light reflection is with slower with the range attenuation of light source; Thereby good decorating effect; When being used for the regeneration activating of uv disinfection or photocatalyst effect might as well light guide reflecting board.It can be widely used in the household electrical appliance such as various air conditioners, refrigerator, ice box.
