Document Type and Number:
WIPO Patent Application WO/2024/051221
Kind Code:
A1
Abstract:
A projection module, which can be applied to a lighting system of a vehicle, other projection environments with limited spaces, etc. The projection module comprises a light source device (101), a lens group (102), a reflection unit (103), and a rotating component (104) connected to the reflection unit (103); light emitted from the light source device (101) passes through the lens group (102) to form a light beam, the light beam being projected to the outside of a vehicle; the reflection unit (103) is used for changing the transmission direction of the light beam, and the rotating component (104) is used for adjusting the position of the reflection unit (103), thereby changing the projection position of the light beam. The short-range/long-range imaging of the projection module outside the vehicle is realized by introducing position adjustment of the reflection unit (103).
