Abstract
Description
Technical Field
[0001] The present application relates to a vehicle lamp, and in particular, to a pixelated signal light optical module. In addition, the present application also relates to a vehicle lamp. Background Art
[0002] With the rapid development of automobile electrification, intelligence and networking, consumers are paying more and more attention to traffic safety and the intelligent interactive functions of vehicles. Pixelated intelligent lights (ISD) with a variety of safety warning patterns and signal interaction functions, and capable of achieving rich personalized animation effects, are one of the key development trends of vehicle signal lights and have been mass-produced on many 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] Existing interactive signal lights mainly use plastic structural parts and LED light sources to divide display pixels, or directly use specially packaged LEDs to form pixel arrays. The technical route is to improve the display fineness of pixels, reduce mosaic phenomena and take into account costs. However, these technical routes all have the problem that the static appearance of the pixels themselves is not refined enough. To address this defect of not being refined enough in appearance, the conventional treatment method is to use dark internal or external accessories to cover up the static defects when the lights are not on. However, this treatment method cannot achieve a refined and diversified appearance, and also brings about a loss of light efficiency and an increase in cost. Another technical route for ISD is to use mini-LED displays or OLED panels with smaller spacing as interactive signal lights, but this type of display not only has a high pixel density, resulting in a significantly higher cost per unit display area, which cannot meet the cost control requirements of the OEM, but also has a relatively monotonous static appearance and lacks diverse expressiveness.
[0004] Based on the above reasons, it is difficult for the existing technology to effectively guarantee the use requirements of the pixelated signal light optical module. Utility Model Content

[0006] Furthermore, the technical problem to be solved by the second aspect of the present application is to provide a vehicle lamp that can simultaneously achieve a static appearance and a lighting effect, has a simple structure, low production cost, and good use effect.
[0007] In order to solve the above technical problems, the first aspect of the present application provides a pixelated signal light optical module, which includes a pixel optical system, a diaphragm, a three-dimensional pattern arranged on the front surface of the diaphragm, and a metal coating along the light propagation path, and the three-dimensional pattern is formed by screen printing.

[0009] Preferably, the outer contour of a single light-emitting unit is a rectangle, a polygon, a circle or other irregular shapes.
[0010] Preferably, it further comprises an internal component, wherein the internal component is arranged between the pixel optical system and the diaphragm.

[0015] Furthermore, the second aspect of the present application also provides a vehicle lamp, comprising a pixelated signal light optical module according to any one of the above technical solutions.
