Abstract
A dual color temperature vehicle lamp able to judge a driving environment based on invisible light includes a vehicle lamp body in the form of an LED. The vehicle lamp body includes a light emitting unit capable of performing a conversion of at least two kinds of color temperature light. A front end face of the vehicle lamp body is provided with at least one invisible light emitting source, at least one reflected light receiver, and a partition plate between the invisible light emitting source and the reflected light receiver. The invisible light emitting source is embedded in a recess at a front end of the vehicle lamp body. The vehicle lamp body includes a preamplifier circuit connected with the reflected light receiver, an MCU connected with the preamplifier circuit, and a wireless transceiver module connected with the MCU therein.
