Abstract
The utility model relates to an optical source color and transmittance adjustable liquid crystal mirror which comprises a protective mirror, an optical color filter mirror, a color changing lamp cover and color changing eyes of an animal model or toy. The utility model makes use of the principle that a liquid crystal case can change the color and the transmittance of the light source and makes use of a manual regulating device and an automatic regulating device for optical source intensity in a working circuit, so the utility model can not only manually regulate the color and the transmittance, but also automatically change the color and the transmittance. The utility model can be widely used for the fields of the daily life, the traffic, the labor protection, the optical instrument, the equipment manufacture, the electric light source, etc.
Description
The utility model belongs to the mirror body of a kind of adjustable light sources color and transmittance, comprises the variable color eyes of protective glasses, optical color filter (as camera filter), variable color lampshade and animal model or toy.
Existing light-sensitive glasses are more common in light-sensitive sunglasses, and the depth changes very slow.Existing people designs a kind of liquid crystal color-changing mirror, for example number of patent application is that 87210593 described " photosensitive electronic liquid crystal light-sensitive glasses " and number of patent application are 87204438 described " photoelectricity light-sensitive glasses ", all be to utilize liquid crystal technology, automatically regulate the color depth of mirror body by light-operated circuit, variable color speed can reach Millisecond, but the depth that only is single color changes, and can not change color itself, and can not manual adjustments.
The utility model relates to and a kind ofly can regulate color, can regulate the mirror body of transmittance color (depth) again, and can select manual adjustments on demand or regulate automatically according to light source is strong and weak.
Fig. 1 is the side sectional view of this mirror body.
(I) and (II) two liquid crystal cells are arranged in the mirror body, and wherein (I) is the colour filter liquid crystal cell, its convertible light source color; (II) for light cuts down liquid crystal cell, the transmittance of its convertible light source.The Liquid Crystal Molecules Alignment mode difference of liquid crystal film (1) in two liquid crystal cells.Is transparency electrode (2), glass substrate (3) and polaroid (4) from liquid crystal film successively to both sides, and wherein being clipped in the middle polaroid of two boxes is that two boxes are shared.
Colour filter liquid crystal cell (I) is to utilize the electro-optic birefringent effect of liquid crystal to carry out work.In the glass substrate (3) of two even orientation process of process, the molecular axis of P type or N type liquid crystal molecule is oriented on the glass substrate and substrate parallel, vertical with substrate on another glass substrate, the molecular axis of the liquid crystal molecule between two substrates is by parallel carry out the transition to gradually vertically (referring to accompanying drawing 2).In addition, make the optical axis of polaroid (4) of glass substrate both sides vertical mutually.The electric field that voltage produced that operating circuit is input on this liquid crystal cell can make the molecular axis orientation direction of an electric field of liquid crystal molecule arrange, because the angle dependence of the polarized light that birefringence causes is in wavelength, thereby in the liquid crystal film of this liquid crystal cell, when the lucky half-twist of light of a certain specific wavelength, the light transmission amount of this wavelength is maximum, and along with the change of voltage, the light wavelength by liquid crystal film changes thereupon, therefore make liquid crystal cell present different colors, play filter action.Change in voltage and liquid crystal film three coloured light transmissivities relation can get the colorama of other wavelength as shown in Figure 2 by the stack of three coloured light.
The Liquid Crystal Molecules Alignment of liquid crystal film (1) is different with colour filter liquid crystal cell (I) in the light valve liquid crystal cell (II), and it is to utilize the twisted effect of liquid crystal molecule to carry out work.(referring to accompanying drawing 3) reversed in the arrangement of the molecular axis of the liquid crystal molecule between the glass substrate (3), 90 ° of being parallel to two substrates from a substrate to another substrate gradually equally also makes the optical axis of two polaroids (4) of light valve liquid crystal cell (II) vertical mutually.Operating circuit is input to voltage on this liquid crystal cell when being zero, and liquid crystal molecule makes polarization of incident light optical axis half-twist, because polarizing axis is parallel to each other, light can pass completely through polaroid makes this liquid crystal cell present water white transparency.When voltage is higher than the threshold voltage of liquid crystal, reduce owing to liquid crystal molecule reversing in electric field makes the light that passes polaroid, thereby the variation of transmittance takes place with change in voltage in liquid crystal cell, promptly the depth of color changes.Relation between voltage and the transmittance as shown in Figure 3.
Utilize operating circuit to control two liquid crystal cell work respectively, just can make the mirror body can the conversion color, again can the conversion transmittance.Transparency electrode (2) the control liquid crystal cell work of operating circuit by connecting with liquid crystal film in the mirror body.
Fig. 4 is an operating circuit.
Colour filter liquid crystal cell (I) and light valve liquid crystal cell (II) are to make its work by the voltage V that operating circuit is exported.
When manual adjustments color or transmittance, K switch
