Abstract

A light adjusting glass based on subtractive colour mixing. The glass comprises two light-transmitting substrates (1) arranged opposite each other. An adjustment region (2) is encapsulated and formed between the two light-transmitting substrates (1). The adjustment region (2) is filled with a liquid crystal mixture, the liquid crystal mixture comprising photopolymerizable liquid crystal monomers, dichroic dyes (4), normal dyes (5), photoinitiators and negative liquid crystals (6). When a voltage is not applied, the negative liquid crystals (6) are in a single-domain arrangement perpendicular to the light-transmitting substrates (1), and molecules of the dichroic dyes (4) are also perpendicular to the light-transmitting substrates (1); and since the dichroic dyes (4) have the poorest light-absorption property and are thus in a colourless state, the transmittance of light rays is highest at this moment. When the voltage is applied, the negative liquid crystals (6) redirect in a direction parallel to the light-transmitting substrates (1), and during the redirection process, the dichroic dyes (4) are driven to rotate, and because of the irregular distribution of polymer networks (3), the negative liquid crystals (6), after the redirection, are in a multi-domain arrangement parallel to the light-transmitting substrates (1), such that the light adjusting glass is converted from a light-transmitting state into a light-scattering state, and according to subtractive colour mixing, the glass is in a fuzzy colour state.

Description

一种基于减色混合法的调光玻璃  Dimming glass based on subtractive color mixing method
技术领域Technical field
本发明涉及建筑家居生活领域，具体涉及一种基于减色混合法的调光玻璃。The invention relates to the field of building home life, in particular to a dimming glass based on subtractive color mixing method.
背景技术Background technique
以往使用彩色玻璃或彩色胶片制成的彩色调光玻璃在通电后其透光率大大地降低,玻璃呈现出很浓的色彩,影响了调光玻璃的使用效果和美观。In the past, the color dimming glass made of colored glass or color film has greatly reduced the light transmittance after being energized, and the glass exhibits a strong color, which affects the use effect and appearance of the dimming glass.
为了实现阳光透射和反射的目的，一般会在玻璃窗上镀膜，使光线中某段波长的光可以被玻璃窗反射或透射。而根据不同的反光和透光需求，可以采用不同材质的膜。In order to achieve the purpose of sunlight transmission and reflection, the glass window is generally coated so that light of a certain wavelength in the light can be reflected or transmitted by the glass window. According to different reflective and light transmission requirements, different materials can be used.
例如，低辐射（Low-E）玻璃在玻璃表面有镀膜层，该镀膜层对可见光具有高度透过率的同时，对远红外辐射热有着较高的反射率，因而室内有隔热保温效果。但Low-E镀 For example, Low-E glass has a coating layer on the surface of the glass. The coating layer has a high transmittance for visible light and a high reflectivity for far-infrared radiant heat, so that the interior has an insulation effect. But Low-E plating
膜玻璃一旦在结构形成之后，其光学性能就不随环境变化或个人喜好进行可逆的双向调节获得冬暖夏凉的效果，难以适应我国大部分四季分明地区的需求。Once the film glass is formed, its optical properties will not be reversible two-way adjustment with environmental changes or personal preference to obtain the effect of warm winter and cool summer, and it is difficult to adapt to the needs of most of the four seasons in China.
同理，镀膜玻璃在成型后可满足对可见光中某段波长的光进行反射的前提下，也无法使该段波长的光能够重新从玻璃中透射。In the same way, the coated glass can satisfy the reflection of light of a certain wavelength in visible light after molding, and the light of the wavelength can not be transmitted again from the glass.
同时镀膜玻璃所采用的反光材料大多是基于金属和金属氧化物掺杂的离子晶体，构成这种玻璃的反光材料容易干扰导航和通信系统，这个缺点不利于镀膜玻璃窗在世界范 At the same time, the reflective materials used in coated glass are mostly based on metal and metal oxide doped ionic crystals. The reflective materials constituting such glass are easy to interfere with navigation and communication systems. This disadvantage is not conducive to the coating of glass windows in the world.
围内进行普及与广泛应用的。It is widely used and widely used in the surrounding area.
基于上述原因，国内外的镀膜玻璃难于广泛地用于大量建筑家居及生活中，而该调光玻璃可增加玻璃的美观效果，实现玻璃的明暗调节，加电时，调光玻璃能够呈现出颜 For the above reasons, coated glass at home and abroad is difficult to be widely used in a large number of building homes and living, and the dimming glass can increase the aesthetic effect of the glass, and achieve the light and dark adjustment of the glass. When the power is applied, the dimming glass can present the color.
色，一定程度上可代替窗帘的作用，解决镀膜玻璃局限性，在车窗玻璃，家居玻璃窗等方面有着良好的应用前景。Color, to a certain extent, can replace the role of curtains, to solve the limitations of coated glass, in the window glass, home glass windows and other aspects have a good application prospects.
