A projection apparatus including a light source, a light valve, a light uniforming device, and a first curved-surface reflection device is provided. The light source provides an illumination beam. The light valve is disposed on a transmission path of the illumination beam for converting the illumination beam into an image beam. The light valve has an active surface that substantially has a rectangular contour. The light uniforming device is disposed on the transmission path of the illumination beam and between the light source and the light valve. The first curved-surface reflection device is disposed on the transmission path of the illumination beam and between the light source and the light valve for reflecting the illumination beam to the light valve. A curvature of the first curved-surface reflection device along a first direction is not equal to a curvature of the first curved-surface reflection device along a second direction.

Projection apparatus

A projection apparatus and a light condensing module are provided. The light condensing module condenses and deflects an incident beam. The light condensing module includes a curving incident surface, a curving outgoing surface and a reflection surface. The curving incident surface receives the incident beam. The curving outgoing surface is disposed on a transmission path of the incident beam from the curving incident surface. The reflection surface is disposed on the transmission path of the incident beam, and located between the curving incident surface and the curving outgoing surface. A ray of the incident beam propagates through the curving incident surface along the optical axis of the curving incident surface, and emits out from the curving outgoing surface along a direction inclined to the optical axis of the curving outgoing surface.

Projection apparatus and light condensing module

A light module includes a first light source. The first light source includes a first light-emitting element and a first lens element. The first light-emitting element includes a first light-emitting chip for emitting a first color light beam and a wavelength conversion material located on the first light-emitting chip for transferring parts of the first color light beam to a second color light beam. The first lens element faces the first light-emitting element and is located on a transmission path of the first color light beam and a transmission path of the second color light beam, and the first lens element includes an optical filter for filtering off the first color light beam and being passed by the second color light beam.

Light module and projection device

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.
