The present disclosure discloses a projection lamp. The projection lamp includes a light-emitting assembly including at least one first non-coherent light source, a light-reflection medium, a first condensing lens, a driving device, a driving gear, and a driven gear. An inner wall surface of the light-reflection medium is formed by mutually connecting a plurality of irregular light reflection surfaces; the first non-coherent light source is arranged in the light-reflection medium; the first condensing lens is arranged above the light-reflection medium; the driving gear is connected to the driving device; and the driven gear is arranged on the light-reflection medium and is engaged with the driving gear to drive the light-reflection medium to rotate. The technical solution of the present disclosure effectively improves the diversity of the light effect of the projection lamp.

A projection lamp with a dual projection function, including a base. The base is provided with a first light-emitting element and a first projection film. Emitted light of the first light-emitting element can pass through the first projection film to be projected outward. The base is provided with a slide projection unit, which includes a light-emitting assembly and a second projection film. Emitted light of the light-emitting assembly can pass through the second projection film to be projected outward. The emitted light of the first light-emitting element passes through the first projection film to be projected outward to form a projection pattern corresponding to the first projection film, and at the same time, the emitted light of the light-emitting assembly passes through the second projection film to form the projection of the slide.

A driver assistance system includes a driver assistance device and a vehicle housing the driver assistance device. The driver assistance device includes a controller and a laser diode operatively coupled with the controller. At least one diffraction optical element is disposed to receive a beam of light from the laser diode and project the beam to a target area. This provides the driver with information regarding their surroundings and vehicle to assist the driver in making decisions regarding to avoid potential issues and obstacles.
