HEADLAMP, AND VEHICLE COMPRISING HEADLAMP
Document Type and Number:
WIPO Patent Application WO/2023/035114
Kind Code:
A1
Abstract:
Provided in the present disclosure are a headlamp, and a vehicle comprising the headlamp. The headlamp comprises: a plurality of LEDs, wherein each of the LEDs can be separately switched on and switched off and can illuminate, when switched on, a corresponding illumination sub-region ahead of a vehicle; a plurality of photoelectric sensors, which match the plurality of LEDs in a manner of corresponding to each other on a one-to-one basis; and a controller, which receives electrical signals from the plurality of photoelectric sensors. Each photoelectric sensor is configured to detect light, which is emitted by a vehicle ahead in the illumination sub-region that corresponds to the matched LED, and to send an electrical signal to the controller when the light emitted by the vehicle ahead has been detected. The controller is configured to switch off the LED, which matches the photoelectric sensor that sends the electrical signal, in response to the received electrical signal from the photoelectric sensor. According to the present disclosure, a glare-free illumination function can be achieved, and travel safety can be improved; and the use difficulty and production cost of glare-free illumination technology can be effectively reduced, thereby facilitating the popularization of glare-free illumination technology.
