The specific embodiment
Describe embodiments of the present invention in detail below with reference to drawings and Examples, how the application technology means solve technical problem to the present invention whereby, and the implementation procedure of reaching technique effect can fully understand and implements according to this.Need to prove, only otherwise consist of conflict, each embodiment among the present invention and each feature among each embodiment can mutually combine, and formed technical scheme is all within protection scope of the present invention.
Such as Fig. 1,2,3,4, shown in 5, this projecting apparatus led light source structure has mainly been utilized the reflection of light principle, and interior minute surface reflective surface area is too small among a small circle owing to the reflective mirror center, therefore, the light that adopts common principle of luminosity that light source is produced converts directional light to and penetrates, thereby solves brightness problem.
For this reason, a kind of projecting apparatus led light source structure of the embodiment of the invention, mainly comprise: light source base 201 and be located at a plurality of small light sources 1012 on the wall 202 around the light source base, each small light source is provided with condenser 1011, base central authorities at light source base arrange a mirror assembly 103, between mirror assembly and a plurality of small light source, be provided with a Light-modulating mirror installing rack 203, and at the Light-modulating mirror installing rack Light-modulating mirror corresponding with each small light source 102 is installed respectively, these Light-modulating mirrors 102 are located at the place ahead of each small light source, wherein, the light that small light source sends converts directional light to and sends after the separately condenser of itself is processed, by after described Light-modulating mirror 102 processing light beam being concentrated into a branch of light pencil directive mirror assembly 103, described mirror assembly reflects away described a plurality of light pencils.
