Abstract

A color temperature control module of a vehicle headlight, installed to a moving vehicle body, includes a light emitting element, a sensing element and an auto switching element. The light emitting element includes a low-penetration light emitting source and a high-penetration light emitting source adjacent to the low-penetration light emitting source. The sensing element senses an ambient environment of the moving vehicle body and sends a sensing signal. The auto switching element, electrically connected to the light emitting element and the sensing element, receives the sensing signal sent by the sensing element to control switching of the low-penetration light emitting source and the high-penetration light emitting source. With the low-penetration light emitting source and the high-penetration light emitting source disposed, the light emitting element is allowed to switch in coordination with changes in the ambient environment of the moving vehicle body to increase driving safety.
