Description

TECHNICAL FIELD

[0001] The present application relates to a vehicle lamp, in particular to a pixelated signal light optical module. In addition, the present application also relates to a vehicle lamp and a forming method of the pixelated signal light optical module. BACKGROUND

[0002] With the rapid development of automobile electrification, intelligence and networking, consumers pay more and more attention to traffic safety and intelligent interaction functions of vehicles. The pixelated intelligent light (ISD) with multiple safety warning patterns and signal interaction functions and capable of realizing rich personalized animation effects is one of the key development trends of vehicle signal lights, and has been mass-produced in many vehicle models. With the development of ISD technology, consumers have higher and higher requirements for the display effect and personalized appearance of ISD, so how to make ISD have a unique appearance and display effect has become an important driving force for the development of vehicle pixel signal lights.

[0003] The existing interactive signal light mainly divides the display pixels by the plastic structure cooperating with the LED light source, or directly uses the special packaged LED to form a pixel array, and the technical route is to improve the display fineness of the pixels, reduce the mosaic phenomenon, and consider the cost. However, these technical routes all have the problem that the static appearance of the pixels is not fine enough. In view of the defect that the appearance is not fine enough, the conventional processing method is to use dark inner or outer accessories to cover up the static defects when not lighting. However, this processing method cannot achieve the appearance performance of refinement and diversification, and also causes loss of light efficiency and increase of cost. Another technical route of ISD is to use a mini-LED display screen or an OLED panel with a small pitch as an interactive signal light, but such a display screen not only has a high pixel density, which significantly increases the cost per unit display area, and cannot meet the cost control requirements of the vehicle manufacturer, but also has a monotonous static appearance and lacks diversity.

[0004] Based on the above reasons, the prior art cannot effectively guarantee the use requirements of the pixelated signal light optical module. SUMMARY

[0005] The technical problem to be solved by the first aspect of the present application is to provide a pixelated signal light optical module, which can realize the static appearance and lighting effect at the same time by setting a film with a three-dimensional pattern in front of the pixel optical system and setting a metal plating layer on the film, and has the advantages of simple structure, low production cost and good use effect.

[0006] Further, the technical problem to be solved by the second aspect of the present application is to provide a vehicle lamp, which can realize the static appearance and lighting effect at the same time, has the advantages of simple structure, low production cost and good use effect.

[0007] In addition, the third aspect of the present application aims to provide a forming method of the pixelated signal lamp optical module, which is simple in steps, convenient to operate and good in use effect.

[0016] Further, the second aspect of the present application also provides a vehicle lamp comprising the pixelated signal lamp optical module according to any one of the above technical solutions.
