The invention discloses projection equipment, and belongs to the technical field of projection. The projection equipment comprises a laser light source, an LED light source, a light combining mirror group, a light machine device and a projection lens. After the projection equipment is applied in the vehicle, the color of the first kind of laser emitted by the laser light source is red laser, so that the light emitting power of the light emitting unit used for emitting the first kind of laser in the laser light source is low and the efficiency of the first kind of laser emitted by the laser light source is low under the condition that the temperature of the environment where the projection equipment is located is high. The color of the LED light emitted by the LED light source in the projection device is the same as the color of the first type of laser emitted by the laser light source, and the light emitting power of the LED light source is less affected by the environment temperature. Therefore, by arranging the LED light source, the first type of laser emitted by the laser light source can be compensated.
