A projection module adapted to be disposed in an electronic device is provided. The electronic device includes a main body and the projection module disposed in the main body. The projection module includes a chassis, a light source, a light valve, a first lens group, and a second lens group. The light source and the light valve are disposed on the chassis. The first lens group is fixed on the chassis. The second lens group is slidably assembled on the chassis and is disposed between the light valve and the first lens group. The light source is capable of providing a light beam, and the light beam is capable of emitting through the light valve, the second lens group, and the first lens group in sequence.

Projection module and electronic device

An illumination system including a first light emitting chip, a chip package, a first dichroic film, and a second dichroic film is provided. The first light emitting chip emits a first light beam. The chip package includes a second light emitting chip and a third light emitting chip. The second light emitting chip emits a second light beam. The third light emitting chip emits a third light beam. The colors of the first, second, and third light beams are different from each other. The first dichroic film is disposed in the transmission paths of the first and second light beams. The second dichroic film is disposed in the transmission paths of the first, second, and third light beams. The first and second dichroic films are not parallel to and do not intersect each other. Besides, a projection apparatus employing the illumination system and another projection apparatus are provided.

Illumination system and projection apparatus

An illumination system includes a light source module, a chromaticity-adjusting light source and a light-combining element. The light source module provides a first color light beam, a second color light beam and a third color light beam. The chromaticity-adjusting light source provides a chromaticity-adjusting light beam. The light-combining element is disposed on the transmission paths of the chromaticity-adjusting light beam and the color light beams provided by the light source module to combine the color light beams with the chromaticity-adjusting light beam into an illumination beam.
