Description

Car light optical system and corner lamp assembly using same Technical Field The utility model relates to the technical field of automobile illumination, in particular to a car lamp optical system and an angle lamp assembly using the same. Background The corner lamp is a lamp for providing auxiliary illumination of a curve when the road environment illumination condition is insufficient, so that the driving safety is guaranteed, and in order to ensure that the automobile is safer in the driving process, more and more host factories require the automobile lamp to increase the function of the corner lamp. In the increasingly complex headlamps, the lamp structure space is smaller and smaller, and the functional space of the corner lamp which is originally used as auxiliary illumination is also more tense, so that higher requirements are put on the optical and structural design of the corner lamp. Most of the conventional corner lamp reflector schemes are LED-level up and down placement and mesh-shaped partition reflector structures, such as, but not limited to, the lamp assembly disclosed in CN222278307U, and for the lamps with such structures, since the power of the corner lamp LED is high, in order to avoid the risk of LED ablating the reflector, a light blocking sheet structure is usually added near the LED or the reflector uses high-temperature PC-HT material, so as to avoid the influence of unnecessary light on the reflector. In order to meet the requirements of regulations and host factories on road illumination performance, the structure not only needs a larger opening space, but also needs to be meshed with the reflecting surface of the reflecting mirror to optimize the light trend, and each more grid of partitions, the reflecting surface is provided with one step, so that a plurality of unnecessary light rays are generated, stray light is generated, and meanwhile, the reflecting surface is provided with too many partitions, so that the appearance defects such as flow marks, air pockets and the like are easily caused. Therefore, there is a problem with the corner lamp structure used in the prior art, and there is a need for further optimizing the structure. Disclosure of utility model A first object of the present utility model is to provide an optical system for a vehicle lamp, which solves the technical problem of optimizing the overall structure thereof. A second object of the present utility model is to provide a corner lamp assembly, which solves the technical problem of optimizing the overall structure thereof.
