The color temperature adjustable filter mirror comprises a liquid crystal box and a power supply, wherein the plane mirror is arranged at one side of the liquid crystal box; the liquid crystal box comprises a transparent substrate A and a transparent substrate B which keep a certain spacing, as well as a sealing edge frame around the transparent substrate A and the transparent substrate B, wherein transparent substrate A, the transparent substrate B and the sealing edge frame form a sealing body; the spacing part between the transparent substrate A and the transparent substrate B includes a liquid crystal layer formed by mixing a liquid crystal material and a spacing material; the transparent substrate A and the transparent substrate B respectively comprise a conductive layer; and the power supply is communicated with the conductive layers of the transparent substrate A and the transparent substrate B. According to the color temperature adjustable filter mirror, by regulating the voltage, orientation movement of liquid crystal molecules is triggered under function of an electric field, to drive orientation of the dichromatic dye molecules, so as to change the absorptivities of the light rays differing in wavelength, and therefore, the color temperature of the light ray penetrating the filter mirror is regulated through an electric control way.
Description
Technical field
The present invention relates to the adjustable filter of a kind of colour temperature, especially the adjustable filter of dye-type liquid crystal colour temperature.
Background technology
Colour temperature be human eye to the sensation of luminophor or white reflection body, this is a kind of sensation of physics, physiology and psychologic comprehensive complicated factor.Colour temperature also is to be used as the very linear module of bright light source color, the temperature when the tolerance foundation makes it send with light source same hue light for the black object with ideal black-body is heated to, linear module ° K(Kelvin) expression.
It is comparatively accurately easy that the tolerance colour temperature can be measured calculating with color meter, colour temperature is to change with artificial mode at TV (luminophor) or photography (refractive body), for example we can control colour temperature with white hot lamp (3200 ° of K) in photography, perhaps we add red filter at camera lens, filter out some red lights and make photo seem the colour temperature height a bit; When colour temperature was higher, color was partially blue, purple, becomes cool tone (Cold Tone), and when colour temperature was low, color was partially yellow, red, is called warm tones (Warm Tone).In general, standard color temperature is 5000K, and white hot lamp always provides the low colour temperature of about 3200 ° of K and is called " warm white ", and the higher color temperature that fluorescent light always provides about 7000 ° of K is called " cold white ".
With camera work now, the application of colour temperature has been quite general, and photographer can do via the value of understanding colour temperature the adjustment of color, so that the photo of taking out can have better colour match.
Yet, the filter of prior art, structure such as Fig. 1, comprise filter (11), it just has been set default value when dispatching from the factory, taking or during show image, always adjusting the colour temperature of taking or observing with a fixing coloured filter, and can't automatically adjust to realize the color optimization of pictures taken according to the situation of environment.Therefore, there is the demand that automatically to regulate the filter of colour temperature according to environmental aspect.
Thereby, need to provide the adjustable filter of a kind of colour temperature to satisfy the demands.

The thickness of described liquid crystal cell is between the 1-1000 micron.
Described conductive layer is the transparency conducting layer that is arranged on the inside surface of described transparency carrier A, B, scribbles oriented layer at described transparency conducting layer, and liquid crystal material is poured into described liquid crystal layer, and sealing forms described liquid crystal cell.
Described transparency carrier is rigid substrates, and such as glass, perhaps described transparency carrier is flexible base, board, and such as plastics, perhaps in the described substrate is rigid substrates, and another is flexible base, board.
Described transparency carrier is glass or plastics.
Can there be functional plated film on the surface of described transparency carrier, and described functional plated film includes but not limited to anti-scratch film, anti-oil film, anti-soil film.
Described transparency carrier comprises not to be with color or to be with coloured transparency carrier, and described transparency carrier includes but not limited to plate the colored transparency carrier of colour film or dyeing processing.
Described liquid crystal material is to utilize the dye-type liquid crystal to be made, and comprises main body liquid crystal, one or more dichroic dyes, chiral material, adjuvant.
Described conductive layer includes electrode, the described electrode UNICOM of the described conductive layer of described power supply and described transparency carrier A, B.
Described filter can be united use with inductor, and it includes but not limited to brightness impression device, colour temperature inductor, temperature inductor.
The thickness of liquid crystal cell is determined that by employed interval insulant as the part of control light intensity, dye liquid crystal is best selection, and it has the transmitance of very high bright attitude; Interval insulant plays a supportive role, and forms presenting of whole minute surface uniform bright attitude or dark attitude; The functional plated film on transparency carrier surface can enlarge the setting range of colour temperature.
Characteristics of the present invention are to pass through regulation voltage, make liquid crystal molecule under the effect of electric field, orientation movement occur, drive the dichroic dye molecular orientation, its absorptivity to the different wave length line is changed, so just can realize by automatically controlled mode the adjustment to the colour temperature of the light that sees through filter.
