Projection lamp assembly and projection lamp

Abstract

The projection lamp assembly comprises a first support and a second support, a groove is formed in the lower end face of the first support and comprises a first contact part and a second contact part, and a first through hole and a second through hole are formed in the first support and the second support; the first contact part abuts against the light-in face of the film, the second contact part is matched with the side wall of the film and limits transverse displacement of the film, and the light-out face of the film abuts against the upper end face of the second support. According to the projection lamp assembly and the projection lamp, the possibility that the film is damaged to generate scraps can be reduced, the scraps and the like can be prevented from entering an optical area, the concentration stability can be improved, and a good projection imaging effect can be formed.

Description

technical field [0001] The invention belongs to the technical field of lighting / signaling devices, and in particular relates to a projection lamp assembly which can be used in projection lamps and a projection lamp containing the assembly. Background technique [0002] Projector lights are able to project logo patterns, artistic texts, various images, the latest ideas of merchants, promotional information, product catalogs, and displays in stores, shopping malls, store entrances, roads, nearby walls or anywhere else in the form of light. The lamps and lanterns can be applied in a variety of scenarios, and the automotive exterior projection lamp is one of them. [0003] At present, the installation structure of the film sheet of the lens group of the automotive exterior projection lamp is an open structure design. The film assembly method is a clearance fit, which cannot prevent dust and film debris from falling into the projection pattern area and causing black spots. With ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the traditional lens structure are: the film is made of glass, and the assembly method is clearance fit. The edge finish of the film is not high after cutting, and debris is easy to remain. When the film is vibrated during product assembly, transportation, vehicle assembly and driving The edge of the film collides with the film holder and the lens to cause the residual debris to fall off. The friction between the film and the film holder produces plastic debris, dust, dust attached to the surface of other parts, and external dust that fall into the projection pattern, resulting in black spots. Affects customer satisfaction and user experience comfort

[0005] In view of the above-mentioned problems, the purpose of the present invention is to provide a lens group and a film installation structure that can be used in automotive projection lamps, which solves the problem of black spots caused by glass shards and external dust falling into the pattern area on the edge of the film It will not be like the traditional lens group structure design, black spot defective products need to be disassembled and reworked, the dismantling process will lead to damage and scrap of the shell, cover, PCBA and other parts, resulting in expensive losses, internal inspection of qualified parts in the transportation And during the vibration process of the vehicle, there will also be black spots, which will lead to the reduction of customer comfort or complaints
