Abstract

The invention relates to a lighting component and a projection device. The lighting component comprises three light source modules capable of outputting a first light, a second light, and a third light, and an integrator. The integrator comprises a first channel, a second channel, a third channel, a first light filtering unit and a second light filtering unit. The first light filtering unit is disposed between the first channel and the second channel, and the second light filtering unit is disposed between the third channel and the second channel. The second light, the first light passing through the first channel and the first light filtering unit, and the third light passing through the third unit and the second light filtering unit can respectively pass through the second channel, therefore the integrator can output the first light, the second light, and the third light. Therefore, the lighting component can be used to output the first light, the second light, and the third light by using the design of the integrator.

Description

technical field [0001] The present invention relates to a lighting assembly and a projection device, in particular to a lighting assembly and a projection device having an integral module with three channels. Background technique [0002] In recent years, due to the development of the electronic industry in the direction of lightness, thinness and compactness, micro-projection devices are bound to become the mainstream trend in the future market. [0003] Please refer to figure 1 , is a schematic structural diagram of a well-known digital light processing projector. A digital light processing projector (Digital Light Processing Projector, DLP Projector) 90 includes a light source module 92, an integrating unit 94, a lens 96, a reflective element 31, a lens group 32, a total reflection prism (TIR Prism) 34, a lens group 36 and digital light Processing Panel (Digital Light Processing Panel, DLP Panel) 38 . The light source module 92 emits a first light 99a, a second light 9...
