Embodiment Construction

[0046] see image 3 , which represents a schematic diagram of a light source module according to a preferred embodiment of the present invention. The light source module 300 includes first and second light sources 31 , 32 , first and second reflectors 33 , 34 and a light integrating device 35 . As shown in the figure, the above-mentioned components are respectively fixed in a light box structure 30; wherein, the first and second reflectors 33, 34 are respectively arranged at an oblique angle to the first and second light sources 31 , 32 on the opposite side of the opening, so that the first and second light rays a, b generated by the first and second light sources 31, 32 are directly incident on the On the light integrating device 35 . In addition, an ultraviolet filter 36, 37 can be arranged on the outside of the exit of the first and second light sources 31, 32, respectively, so that the first and second light rays a, b enter the first and second reflectors. Before mirror ...

Abstract

The present invention provides a projection system light source module. Said light source module contains first and second light source for generating first and second light; first and second reflection mirror respectively located said first and second light path for controlling said first and said second light transferring direction; one light accumulation device having first prism column, second prism column and one light accumulation column, configured rear said first and second reflection mirror; wherein when said first and second light incoming said light accumulation device through primary reflection, each light respectively received by said first and prism of prism column, and through total reflection to collect to said light accumulation column for making homogenization.

Description

technical field [0001] The present invention relates to a light source module of a projection system, in particular to a light source module used in an L-shaped light-mechanical projection system. Background technique [0002] In recent years, projection display systems have been widely used in various fields, such as common projection briefing and multimedia display systems in conference halls, image projection systems in movie theaters, and increasingly popular household front-projection or rear-projection TVs. machine etc. To put it simply, common projection systems can be divided into main components such as light source modules, light splitting / combining optical elements, light valve modules, and lens groups. Among them, the light source module is the most important factor affecting the brightness and color uniformity of the projection system. member. A light source module currently used in a projection system is mainly composed of a light source and a plurality of op...
