Description

Technical Field

[0001] This utility model relates to the field of auto parts, specifically a dynamic projection lamp with an integrated multi-lens structure. Background Technology

[0002] Traditional automotive MLA dynamic projection lights use a collimating lens structure that consists of multiple independent collimating lenses spliced ​​together. This design leads to assembly errors between the individual collimating lenses, and assembling multiple collimating lenses is also quite cumbersome. Furthermore, because there are four independent collimating lenses, it's impossible to create a structure that positions them in relation to the LEDs, significantly affecting the positional accuracy between the LEDs and the collimating lenses. In addition, previous automotive MLA dynamic projection lights were prone to positional discrepancies between the lamp panel and the collimating lens, and the connection structure between the lamp panel, light shield, collimating lens, and MLA cover plate was not robust enough, making the installation of the collimating lens inconvenient.
