Description

Integrated light-guiding type car lamp lighting optical system Technical Field The invention relates to the technical field of automobile lamps, in particular to an integrated light guide type automobile lamp lighting optical system. Background With the rapid development of the automobile industry, the automobile lamp is not only capable of meeting the basic lighting and signal indication functions, but also a core component for highlighting the design language of the automobile and improving the attractiveness of the product. The design of the automobile lamp is increasingly rich and diversified, and the corresponding lighting effect also develops towards the directions of multiple luminous areas and personalized patterns so as to meet the requirements of consumers on high-end and customization of the appearance of the automobile. In the technical scheme for realizing the lighting effect of multiple lighting areas, the traditional prior art is mainly divided into a scheme of direct LED (light emitting diode) irradiation and thick-wall parts or LED and reflectors. The two schemes generally need one LED light source to correspond to one or a few light-emitting areas, when the lamp needs to realize a plurality of light-emitting areas, the number of LED lamp beads is inevitably increased greatly, the cost of the light source is directly improved, the linkage problems of complex circuit design, complicated assembly procedures and the like are also brought, and finally the comprehensive cost of the whole lamp product is high. The automobile tail lamp with compact structure as disclosed in patent CN211032354U comprises a lamp shell, a circuit board, an LED light source and a light guide structure, wherein the circuit board, the LED light source and the light guide structure are all positioned in the lamp shell, the light guide structure comprises a light guide strip and a light guide thick-wall piece which are arranged side by side, a positioning hole is formed in the lamp inner shell, a boss structure penetrating through the positioning hole is arranged on the light guide thick-wall piece, a jack for inserting the light guide strip is formed in the lamp inner shell, the light guide strip is arranged in the jack, and the LED light source is arranged at the lower part of the circuit board and the top of the light guide strip.
