Abstract

This invention discloses an automotive lens with a composite electrochromic glass layer.

Description

Technical Field

[0001] This utility model relates to the field of automotive optical components, and in particular to an automotive lens with a composite electrochromic glass layer. Background Technology

[0002] An automotive lens is an optical element used in automotive headlights. It is typically made of transparent optical glass and can improve the illumination effect of the light.

[0003] However, existing automotive lenses generally offer only average transparency; furthermore, their light transmission is limited, resulting in a fixed intensity of headlights that is difficult to adjust based on different environmental and weather conditions.

[0004] Therefore, existing automotive lenses suffer from issues such as mediocre visual effects and the inability to adjust light transmission. Utility Model Content

[0005] The purpose of this invention is to provide an automotive lens with a composite electrochromic glass layer. This invention not only improves visual effects but also has the advantage of adjustable light transmittance.

[0006] The technical solution of this utility model is as follows: an automotive lens with an electrochromic glass layer, comprising a lens body made of optical glass through molding; the front side of the lens body is provided with an aspherical convex light-emitting surface, the rear side of the lens body is a planar light-incoming surface, the light-incoming surface is compositely connected with electrochromic glass, and the edge of the lens body is provided with an outwardly protruding snap-fit ​​mounting edge.

[0007] In the aforementioned automotive lens with an electrochromic glass layer, the electrochromic glass includes a first transparent conductive layer, an electrochromic layer, a second transparent conductive layer, and a transparent substrate layer arranged sequentially. A power supply with a controller is electrically connected between the first transparent conductive layer and the second transparent conductive layer. The first transparent conductive layer is composited with the light-gathering surface.

[0008] In the aforementioned automotive lens with an electrochromic glass layer, the edge of the electrochromic glass is connected to an insulating sealant layer.

[0009] In the aforementioned automotive lens with an electrochromic glass layer, the insulating sealant layer is covered with an opaque protective layer.

[0010] Compared with existing technologies, this invention combines electrochromic glass with the light-incoming surface of the rear plane of the lens glass. The electrochromic glass changes color, thereby altering the visual effect of the car lens and making it different from traditional car lenses, giving it a more premium feel. At the same time, by changing the transparent electrochromic glass to a dark color, the light transmission performance of the car lens can be reduced, allowing the car lens to adjust its light transmission according to the light intensity requirements under different environmental and weather conditions.

[0011] Furthermore, in this invention, the electrochromic glass uses the lens body as the base layer on one side, and the first transparent conductive layer, the electrochromic layer, and the second transparent conductive layer are composited within the lens body and the transparent base layer on the other side, forming a composite of the lens body and the electrochromic glass, thus saving overall manufacturing costs.

[0012] The edges of the electrochromic glass are connected with an insulating sealant layer to ensure the working stability of the electrochromic glass; by wrapping an opaque protective layer over the insulating sealant layer, the electrochromic glass is not easily damaged and has good durability.

[0013] Therefore, this invention not only improves visual effects, but also has the advantages of adjustable light transmittance, low manufacturing cost, and good durability. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example. An automotive lens with a composite electrochromic glass layer, configured as follows: Figure 1 and 2 As shown, the lens body 1 is made of optical glass through molding; the front side of the lens body 1 is provided with an aspherical protrusion light-emitting surface 2, the rear side of the lens body 1 is a flat light-incoming surface 3, an electrochromic glass 4 is compositely connected on the light-incoming surface 3, and the edge of the lens body 1 is provided with an outwardly protruding snap-fit ​​mounting edge 5.

[0019] The electrochromic glass 4 includes a first transparent conductive layer 6, an electrochromic layer 7, a second transparent conductive layer 8, and a transparent substrate layer 9 arranged sequentially. A power supply 10 with a controller is electrically connected between the first transparent conductive layer 6 and the second transparent conductive layer 8. The first transparent conductive layer 6 is composite with the light-receiving surface 3.

[0020] The edge of the electrochromic glass 4 is connected to an insulating sealant layer 11; the insulating sealant layer 11 is covered with an opaque protective layer 12.

[0021] Working principle: The lens body 1 can be installed into the car headlight base, and the elastic claws on the base can engage the protruding mounting edge 5 of the lens body 1, so that the lens body 1 can be stably installed in the base; after the light source in the car headlight emits light, the light is focused by the condenser cup and enters through the light-inlet surface 3 of the lens body 1 through the electrochromic glass 4 and then exits through the light-outlet surface 2 of the lens body 1. Since the light-outlet surface 2 is an aspherical protrusion, it can focus the light and illuminate a certain area in front.

[0022] When driving at night in well-lit conditions, the controller can power the first transparent conductive layer 6 and the second transparent conductive layer 8 of the electrochromic glass 4 through the power supply 10. This causes the electrochromic layer 7 to darken, reducing the light intensity passing through the electrochromic glass 4 and thus lowering the intensity of light emitted from the light-emitting surface 2 of the lens body 1, preventing glare caused by excessive light intensity. When driving on roads with insufficient lighting, the controller can power the electrochromic glass 4 through the power supply 10, making the electrochromic layer 7 transparent again and increasing the intensity of light emitted from the light-emitting surface 2 of the lens body 1, resulting in better illumination.

[0023] Before parking, users can also use the controller to make the electrochromic glass 4 change color by applying electricity, so that the lens body 1 in the car headlight has a color that is different from traditional transparent car lights, giving it a high-end feel.

[0024] In the electrochromic glass 4, the lens body 1 serves as the base layer on one side. The first transparent conductive layer 6, the electrochromic layer 7, and the second transparent conductive layer 8 are composited within the lens body 1 and the transparent base layer 9 on the other side, forming a composite of the lens body 1 and the electrochromic glass 4, thus saving overall manufacturing costs. An insulating sealant layer 11 is connected to the edge of the electrochromic glass 4 to ensure its operational stability. An opaque protective layer 12 is wrapped around the insulating sealant layer 11, making the electrochromic glass 4 less prone to damage and providing good durability.
