Abstract

The invention provides a projecting apparatus. A structure intensity after a light source module and a ray machine are combined can be increased and an internal space of the projecting apparatus is effectively used. The projecting apparatus comprises a shell, a first frame body, a second frame body, the light source module and the ray machine. The second frame body is arranged in the shell. The first frame body possesses a first accommodation space. The second frame body possesses a second accommodation space. A first opening of the first accommodation space along a first direction is vertical to a second opening of the second accommodation space along a second direction. The second frame body and the first frame body are connected so that the second accommodation space is connected to the first accommodation space. The light source module is arranged in the first accommodation space. The ray machine is arranged in the second accommodation space. An optical axis of first light emitted by the light source module forms a first optical axial plane in the first frame body. The first light emitted by the light source module enters into the ray machine and then forms second light. An optical axis of the second light forms a second optical axial plane in the second frame body. The first optical axial plane is vertical to the second optical axial plane.

Description

technical field [0001] The invention relates to the field of projection devices, in particular to a light emitting diode light source projector. Background technique [0002] LED (Light Emitting Diode, light-emitting diode) light source projector, in order to ensure that the red, green and blue light sources are accurately projected onto the DMD (Digital Micromirror Device, digital micromirror device), it must be designed in a limited space that can place red A light source module for green and blue light sources. In the prior art, the opening of the housing of the LED light source module is in the same direction as the opening of the housing of the optical machine, and the optical axis plane formed by the light in the LED light source module and the optical axis plane formed by the light in the optical machine They are parallel to each other. In this way, the structural strength of the combination of the LED light source module and the light engine is insufficient and the ...
