Abstract
The utility model discloses composite glass with adjustable brightness, which comprises a glassy layer, a polaroid is respectively arranged on both sides of the glassy layer, wherein one piece of the polaroids is fixed on the glassy layer, and the other piece of the polaroids is abutted on the glassy layer, is arranged on a rotating shaft and can rotate around the rotating shaft. As a further improvement of the utility model, the glassy layer of the composite glass is in a composite structure and is composed of two pieces of glass, a liquid crystal layer, a protective frame and an electrode, wherein the liquid crystal layer is positioned between the two pieces of glass, the protective frame is coated outside the glassy layer and the electrode is connected with the liquid crystal layer and is fixed on the protective frame. Through the rotation of the polaroids and different voltages applied to the liquid crystal layer by the electrode, the brightness and the color of the glassy layer are changed. The utility model can be conveniently used.
Description
Technical field
The utility model relates to a kind of optical material.
Background technology
At present, widely used various glass or eyeglass, as the dark-brown glass that uses on clear glass, the door and window and the filter glass of vehicle window, all be the single fixing glass of light transmittance and color, can not change brightness (light transmittance) and color according to people's needs with outdoor intensity of sunshine, seasonal variations, can't adapt to the needs of the modern life.
The utility model content
The purpose of this utility model provides a kind of compound glass of simple in structure, adjustable brightness.
The purpose of this utility model is achieved in that this compound glass comprises glassy layer and glassy layer both sides polaroid, wherein a polaroid is fixed on the glassy layer, another piece polaroid is near glassy layer, and is installed in the rotating shaft, can be around its rotating shaft rotation, rotating shaft can be arranged on glass, also can be arranged on other annex, like this, according to the polarisation of light principle, when the phase place that rotates to two polaroid institute printing opacities is in full accord, the light transmittance maximum of compound glass; When the phase place that rotates to two polaroid institute printing opacities was opposite fully, the light transmittance minimum of compound glass did not promptly have light transmission, and visual effect is dark fully; Rotate polaroid between above-mentioned both positions continuously, light transmittance is the continually varying process.
As further improvement of the utility model; the glassy layer of this compound glass is a composite construction; it is by two blocks of glass; liquid crystal layer between two blocks of glass; be coated on the outer bearer bar of glassy layer; the electrode that links to each other with liquid crystal layer and be fixed on the bearer bar is formed; the glassy layer both sides are respectively arranged with fixedly polaroid and movable polaroid; movable polaroid can be around its rotating shaft rotation; when adding voltage by the electrode pair liquid crystal layer; just can change the ordered state of liquid crystal molecule by the size that changes voltage or electric current; thereby present different optical characteristics; realize changing the purpose of glassy layer color; add the effect of polaroid, change the light transmittance of glassy layer.
Advantage of the present utility model is: simple in structure, brightness and color easy to adjust.
Description of drawings
Fig. 1 is the cutaway view of first specific embodiment of the utility model.
Fig. 2 is the cutaway view of another specific embodiment of the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
By shown in Figure 1, the compound glass of a kind of adjustable brightness of the present utility model, comprise glassy layer 1, glassy layer 1 both sides respectively are provided with a polaroid 2,3, and wherein polaroid 2 Pastings are fixed on the glassy layer 1, and polaroid 3 is near glassy layer 1, and be installed in the rotating shaft, can rotate polaroid 3 continuously around its rotating shaft rotation, light transmittance can change continuously.
By shown in Figure 2; the compound glass of another kind of adjustable brightness of the present utility model; the glassy layer of this compound glass is a composite construction; it is made up of two blocks of glass 5, the liquid crystal layer 4 between two blocks of glass, the electrode 7 that is coated on bearer bar 6 outside the glassy layer, links to each other with liquid crystal layer and is fixed on the bearer bar; the glassy layer both sides are respectively arranged with fixedly polaroid 2 and movable polaroid 3; when adding voltage by 7 pairs of liquid crystal layers 4 of electrode; just can change the glassy layer color by the size that changes voltage or electric current; add the effect of polaroid, change the light transmittance of glassy layer.
Glass pane with the utility model is made owing to can regulate brightness, can no longer need curtain; The sunglasses of making can be according to outdoor intensity of sunshine, regulated at will brightness; As the color and the brightness of need change glass, then can use the compound glass of second specific embodiment.
Claims (2)
1. the compound glass of an adjustable brightness comprises glassy layer, it is characterized in that the glassy layer both sides respectively are provided with a polaroid, and wherein a polaroid is fixed on the glassy layer, and another piece polaroid is near glassy layer, and is installed in the rotating shaft.
2. the compound glass of a kind of adjustable brightness according to claim 1; it is characterized in that described glassy layer is a composite construction, it is made up of two blocks of glass, the liquid crystal layer between two blocks of glass, the electrode that is coated on bearer bar outside the glassy layer, links to each other with liquid crystal layer and is fixed on the bearer bar.
