Integration column with high heat resistance

Abstract

The invention provides an integration column with high heat resistance. The integration column comprises a frame body with two open ends, the inner wall of the frame body is a rectangular through hole, and each inner wall is concavely provided with a mounting groove. The two ends of each mounting groove extend to the two ends of the frame body, each mounting groove is provided with a reflective lens, and a light path channel is formed among the multiple reflective lenses. At least one groove is formed at the bottom of each mounting groove, and the grooves are formed along the length directionof the frame body and extend to the two ends of the frame body. A heat conduction piece is arranged in each groove, an end cover is arranged at one end of the frame body, and a through hole is formedin the end cover to correspond to the light path channel. A clamping cavity and a placing cavity are formed on the end cover, the clamping cavity corresponds to and is communicated with one end of thegroove, the placing cavity is communicated with the clamping cavity, and a fan blowing air outwards is installed in the placing cavity. The integration column is novel in structure, can provide the good heat conduction and heat dissipation effects, can effectively prevent the lens of the integration column from deforming due to the over-high temperature, and guarantees the projection effect.

Description

technical field [0001] The invention relates to the field of optical elements of projection equipment, more specifically, to a high heat-resistant integrating column. Background technique [0002] Digital projectors use high-power bulbs as light sources, and the high-temperature illumination beams generated by them are focused on the entrance of the integrating column through lenses to form high-temperature, bright and uniform beams, which are projected onto the screen through the color wheel and digital micromirror components Make the picture clearer and brighter. [0003] Integrators can be divided into two types: hollow integrating column and solid integrating column according to the structure. The hollow integrating column has less heat accumulation problem than the solid integrating column. In a high-temperature working environment, if the heat dissipation effect is poor, the lens of the integrator will be warped and deformed, which will affect the projection effect. ...
