Problems solved by technology

[0003] Optical filters in the prior art are usually made by adding dyes of specific colors to plastic or glass sheets, so the color and transmittance of the optical filters are fixed, but the light in the environment is variable, and different users The needs and preferences for light are different, which leads to the need to manually replace different filters when the user's demand for the current light changes during use, which increases the inconvenience and cost of user operations. The frequent replacement process of light sheets may also easily lead to early damage to the mechanical structure of the equipment

Embodiment 1

[0039] Embodiment 1 of the present invention provides a filter device, which includes: an electrochromic device; figure 1 As shown, the electrochromic device includes a stacked electrochromic layer 10, a first stacking layer 20, and a first substrate 30; wherein, the electrochromic layer 10 includes: a first conductive substrate, a color-changing material layer, and a stacked stacked layer in sequence. second conductive substrate. Wherein, the color-changing material layer is a layer of adjustable transmittance composed of one or more layers of liquid or solid materials, such as polymer dispersed liquid crystal (Polymer Dispersed Liquid Crystal, PDLC) glass, suspended particle device (Suspended Particle Device, SPD ) and electrochromic (Electrochromic, EC) and other types.

[0040] Specifically, EC is a phenomenon in which the optical properties (reflectivity, transmittance, absorbance, etc.) of a material undergo a stable and reversible color change under the action of an ap...

Embodiment 2

[0056] Embodiment 2 of the present invention provides a filter device. The technical solution of this embodiment is further refined on the basis of the technical solution of the above embodiment, optionally, such as Figure 4 As shown, the surface on the first substrate 30 away from the first stacking layer 20 is a curved surface, Figure 4 The optimization based on the filter device including the second stacking layer 40 and the second substrate 50 is shown as an example.

[0057] Specifically, when the filter device provided in this embodiment is applied, the light can be incident from the second substrate 50 and exit from the first substrate 30 after the light filtering is completed. The first substrate 30 includes two surfaces that are close to and far from the first stacking layer 20 , and the light is specifically emitted from the surface of the first substrate 30 that is far away from the first stacking layer 20 . When the surface away from the first superimposed laye...

Embodiment 3

[0060] Embodiment 3 of the present invention provides a filter device. The technical solution of this embodiment is further refined on the basis of the technical solution of the above-mentioned embodiment. Optionally, the electrochromic layer 10 includes a plurality of electrochromic regions arranged in tiles, and the filter device adjusts each electrochromic region separately. The transmittance of the electrochromic regions; the color-changing material layers of the plurality of electrochromic regions include at least two materials.

[0061]Specifically, the cross-section of the electrochromic layer 10 can be of any shape, and all the electrochromic regions included on the electrochromic layer 10 can fill the entire electrochromic layer 10, or only occupy a part of the region, and at the same time, The multiple electrochromic regions can be adjacent or non-adjacent. When all the electrochromic regions only occupy a part of the electrochromic layer 10, a fly-eye lens can be a...

Abstract

The embodiment of the invention discloses a light filtering device, a camera and a light-emitting light source. The light filtering device comprises: an electrochromic device. The electrochromic device comprises an electrochromic layer, a first superposition layer and a first substrate which are arranged in a stacked mode. The electrochromic layer comprises a first conductive substrate, a color-changing material layer and a second conductive substrate which are sequentially stacked. According to the technical scheme, under the condition that the optical filter does not need to be replaced, thefiltered light intensity can be adjusted by applying corresponding voltage to the electrochromic device as required, so that the expenditure cost of a user and the loss of a mechanical structure of equipment needing light filtering are reduced, meanwhile, the electrochromic layer is protected; and the light filtering device can be fixed to the equipment needing light filtering more conveniently,and the structural stability of the light filtering device is enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the field of optical technology, and in particular to a filter device, a camera, and a light source. Background technique [0002] With the development of various display technologies, optical filters are becoming more and more inseparable from our lives. For example, it has a wide range of applications in the fields of medical treatment, automobiles, business offices, and optical communications, especially for imaging systems currently on the market, such as security cameras, cameras, and mobile terminal cameras. A filter is used to partially or completely block light of a certain color. [0003] Optical filters in the prior art are usually made by adding dyes of specific colors to plastic or glass sheets, so the color and transmittance of the optical filters are fixed, but the light in the environment is variable, and different users The needs and preferences for light are different, which leads to...
