Title:
VEHICLE LIGHTING DEVICE, VEHICLE INVISIBLE LIGHT PROJECTION DEVICE, AND TARGET OBJECT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/104286
Kind Code:
A1
Abstract:
Disclosed are a vehicle lighting device, and an invisible light projection device comprising the vehicle lighting device. The vehicle lighting device comprises a light source (1), a rotary actuator (2), a light distribution element (3) and a controller (100), wherein the light source (1) is mounted on a rotation shaft of the rotary actuator (2); and the controller (100) is adapted to control a light-emitting state of the light source (1) so as to create different light forms. The vehicle lighting device can create a wide range of light distribution with less light sources (1), and has a good heat dissipation capability. The invisible light projection device comprises the vehicle lighting device, which is provided with the light source (1) of an invisible light-emitting element (12), the rotary actuator (2), and the controller (100), wherein the controller (100) is adapted to control the light-emitting state of the invisible light-emitting element (12) at different rotation positions so as to create light distribution of invisible light. The invisible light projection device can carry out invisible light irradiation on a dark area of vehicle lighting, so as to detect safety risks that a driver cannot see, thereby improving the vehicle safety performance. A target object detection device is further disclosed.
