Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, and in particular to a vehicle signal lamp and a vehicle. Background Art

[0002] In order to stably fix the light guide inside the lamp body, in most cases, a fixed structure needs to be grown on the light guide. Because the light guide is an optical component, the light is totally reflected inside the light guide, so when the light guide contacts the fixed structure, a sudden change in the light path will occur, resulting in a bright spot.

[0003] The general way to cover bright spots is to apply black paint on the installation structure that produces bright spots or use a sleeve to cover the light-emitting surface of the light guide with bright spots. However, these two methods often have great limitations. Applying black paint will add additional processes and is difficult to control. In addition, black paint absorbs heat severely, which will increase the risk of burns to the light guide and surrounding contact parts. The difficulty of using the sleeve solution is that both the appearance and the installation stability must be considered. If the sleeve is not firmly fixed, the shading effect will be greatly reduced, and abnormal noise may occur during the vibration process. In addition, the sleeve has requirements for the installation space, which will also bring challenges to the spatial layout of the entire lamp. Utility Model Content

[0041] The light guide 1 can be a circular light guide, or a thick-walled part or a light curtain. The light guide mounting structure 5 is a light guide mounting wing, which is integrally formed with the light guide 1. Generally, there are two light guide mounting wings, which are symmetrically distributed.

The flexible film 2 is adhered to the connection between the light guide 1 and the light guide mounting structure 5 through the adhesive surface layer 203 .

[0043] The materials of the transparent layer 202 , the frosted layer 201 , and the adhesive surface layer 203 are PC material, PC material, and PU material respectively.

[0044] The thickness of the flexible film 2 is 0.15 mm to 0.2 mm. The flexible film 2 is wound on the light guide 1. In order not to affect the appearance, the end of the flexible film cannot be on the light-emitting surface of the light guide after winding.

[0045] The PCB board 4 is a PCB board, the light source 3 is an LED light source, and the light source 3 is located on the PCB board 4 .

[0046] This embodiment also provides a vehicle, comprising the above-mentioned vehicle signal light.

[0047] This embodiment uses a flexible light-transmitting film attached to the light guide to reduce the bright spots on the light guide and increase the uniformity of the light guide.

[0049] Embodiment 2:

[0050] Those skilled in the art may understand this embodiment as a more specific description of Embodiment 1.

[0051] This embodiment provides a structure for improving the uniformity of vehicle signal lights, including a light guide 1, a flexible film 2, a light source 3, a PCB board 4, a light guide incident end 101, a light guide mounting structure 5, a light guide bracket 6, and a light guide adapter 7. The light source 3 is an LED light emitter, the PCB board 4 is a PCB board structure, and the light guide mounting structure 5 is a light guide mounting wing.

[0052] Among them: the light source 3 is welded on the PCB board 4. After the light source 3 is powered on, the light enters the light guide 1 through the light guide incident end 101. The light guide installation structure 5 is grown on the light guide 1. There is an optical surface behind the light guide. The light will be totally reflected by the optical surface of the light guide and will be emitted through the light guide light emitting surface. Because the light guide installation structure and the light guide bracket will be in direct contact, when the light is totally reflected, a part of the light will be superimposed at the contact light spot position 102 area. Looking from the light guide light emitting surface, a bright spot will appear in the light spot position 102 area.

[0053] The flexible film 2 is attached to the bright spot on the light-emitting surface of the light guide. The flexible film 2 is composed of three parts: a transparent part, a frosted surface, and a glue surface. The transparent part has a very strong light-transmitting effect, mainly to be able to project light out. The function of the frosted surface is to disperse the light transmitted from the bright spot on the light-emitting surface of the light guide, dilute the bright spot, and thus improve the uniformity of the light guide. The function of the glue surface is to stick the flexible film to the desired position.

[0054] Furthermore, in order to ensure that the flexible film 2 attached to the light guide 1 does not affect the appearance of the light guide, the thickness of the flexible film 2 is controlled to be between 0.15 mm and 0.2 mm, and the end of the flexible film 2 cannot be located on the light emitting surface.

[0055] Furthermore, the flexible film 2 can be attached to the light guide 1 or wound. In order to ensure the uniformity of the light emitting surface, the winding thickness needs to be determined according to the actual situation of the bright spot during winding.

[0056] Furthermore, the uniformity of the light-guiding surface can be changed by adjusting the size of the grains of the frosted surface of the flexible film.

[0057] Furthermore, the light guide may also be other types of parts such as a thick-walled part or a light curtain.

[0058] Furthermore, the light guide mounting wings grow on the light guide 1, and both are located on the same light guide.

[0059] The utility model reduces bright spots on the light guide by attaching a flexible film on the light guide, thereby increasing the uniformity of the light guide.
