Abstract
The utility model discloses a photochromic lens. Two layers of photochromic films are glued to the outer surface of a plastic film. The photochromic lens is simple in structure; the number of layers of the photochromic films is increased on the plastic film, so that the photochromic speed is accelerated; furthermore, the photochromic films are even in photochromic process, and better in photochromic effect.
Description
Technical field
The utility model relates to the technical field of glasses, special relevant with the structure of color-changing lens.
Background technology
Color-changing lens, claim again by " sensitization eyeglass ", is to add electrochromic substance (chemical substances of silver halide etc.) on eyeglass, allow otherwise transparent colourless eyeglass, meet strong illumination, will become colored lens, do protection, so be to be suitable for indoor and outdoor to use simultaneously.
In prior art, color-changing lens be by immersion way eyeglass adhere to variable color liquid, thereby realize the combination of electrochromic substance and eyeglass.This immersion way makes the two sides of color-changing lens all adhere to electrochromic substance, adheres to the phenomenons such as inhomogeneous, easy appearance extension liquid, directly affects the color changeable effect of eyeglass.
Afterwards, have the dealer to adopt color-changing membrane and the bonding mode of sheet to make color-changing lens, color-changing membrane is even coating variable color liquid and making on substrate, and substrate adopts or akin material identical with sheet, and color-changing membrane can directly be buied to producer.This color-changing lens can reach the purpose of even variable color, and color changeable effect is better.But because bonding individual layer color-changing membrane on sheet only, so variable color speed is slow.
In view of this, the inventor is improved the structure of existing color-changing lens, develops a kind of Novel color-changing eyeglass, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of color-changing lens, makes variable color speed faster.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of color-changing lens, at the bonding two-layer color-changing membrane of the outside surface of sheet.
Described sheet is PC sheet (polycarbonate), and color-changing membrane is at the TAC(Triafol T) evenly tint variable color liquid and make on sheet.
After adopting such scheme, the utility model is simple in structure, increases the number of plies of color-changing membrane on sheet, variable color speed is accelerated, and the variable color of color-changing membrane is even, and color changeable effect is better.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structure enlarged drawing of the present utility model.
Label declaration
Embodiment
As depicted in figs. 1 and 2, be a kind of color-changing lens that the utility model discloses, at the bonding two-layer color-changing membrane 2 of the outside surface of sheet 1.Sheet 1 specifically can be the PC sheet, and color-changing membrane 2 is evenly tint variable color liquid (photochromic layer 22) and make on TAC sheet (substrate 21).The utility model, by increase the number of plies of color-changing membrane 2 on sheet 1, can make variable color speed accelerate.
Transmittance before the utility model variable color is about 75～78%, with the UV light irradiation of power 36W after 15 seconds, transmittance can drop to 12～16%, and the color-changing lens of prior art individual layer color-changing membrane only can drop to 35% from 78%, and color changeable effect of the present utility model is obviously better.
These are only specific embodiment of the utility model, is not the restriction to protection domain of the present utility model.All equivalent variations of doing according to the mentality of designing of this case, all fall into the protection domain of this case.
Claims (2)
1. a color-changing lens, is characterized in that: at the bonding two-layer color-changing membrane of the outside surface of sheet.
2. a kind of color-changing lens as claimed in claim 1, it is characterized in that: described sheet is the PC sheet, color-changing membrane is evenly tint variable color liquid and make on the TAC sheet.
