Embodiment
For making technological means of the present invention and operation have further understanding and understanding, hereby coordinating accompanying drawing for embodiment, being described in detail as follows.
Please refer to shown in Fig. 1 to Fig. 4, micro-projection arrangement provided by the present invention, by being made up of a pedestal 11 and several light source module 12.
The inside of this pedestal 11 is provided with a guiding face 111, and it was one skewed (as shown in Figure 3 and Figure 4).
These light source modules 12 are arranged on this pedestal 11, these light source modules 12 are a hollow base frame 121, it has a positioning seat 122, a glide plane 1221 is provided with in the bottom of this positioning seat 122, for being an arc structure (as shown in Figures 2 and 3), make this glide plane 1221 can slippage on this guiding face 111, allow these light source modules 12 can slide onto diverse location by this positioning seat 122 at the guiding face 111 of this pedestal 11, to change the launching position of the light of these light source modules 12, and the crevice projection angle of light of these light source modules 12 is adjusted by the arc structure of this glide plane 1221.
These light source modules 12 are provided with a collimating mirror 123 and a light-emitting component 124(as shown in Figure 2), this light-emitting component 124 wears in this hollow base frame 121, and be arranged in this hollow base frame 121 after being socketed with this collimating mirror 123, this collimating mirror 123 is allowed to be positioned at the front end of this light-emitting component 124, and this light-emitting component 124 launches a light source towards this collimating mirror 123, this light source is made to form this light by this collimating mirror 123.
This positioning seat 122 is for being located at the bottom of this hollow base frame 121.
Moreover these light source modules 12 form it for first carrying out assembling by this hollow base frame 121, this collimating mirror 123 and this light-emitting component 124, then putting into this pedestal 11, forming micro-image device 1 to assemble.
When these light source modules 12 in micro-projection arrangement 1, by the glide plane 1221 of the positioning seat 122 of these light source modules 12, carry out sliding onto diverse location at the guiding face 111 of this pedestal 11, the launching position of the light that these light source modules 12 produce can be changed.
And the ray cast that micro-projection arrangement 1 projects on a screen (not shown) time, when having the phenomenon of Light distribation inequality, then finely tuned by these light source modules 12 of micro-projection arrangement 1, carrying out in trim process, finely tuned by the glide plane 1221 of the positioning seat 122 of these light source modules 12, arc structure by this glide plane 1221 finely tunes the crevice projection angle of these light source modules 12 on this guiding face 111, make the crevice projection angle of these light source modules 12 after fine setting, allow the light source that the light-emitting component 124 of these light source modules 12 produces, at the light formed after this collimating mirror 123, several optical frames 13 again through being located in micro-projection arrangement 1, 14, 15(is as shown in Figure 1) and several catoptron 16, 17(is as shown in Figures 1 and 3) reflection after, and through the imaging modules 18(that is located in micro-projection arrangement 1 as shown in Fig. 1 and Fig. 4) give projection and go out, make the light that projects away can be evenly distributed, to improve the light that existing micro-projection arrangement projects, the shortcoming of Light distribation inequality can be caused on the screen.
Known whereby, the light source module of the micro-projection arrangement of the present invention and the adjust structure of use thereof, for the glide plane 1221 of the positioning seat 122 through these light source modules 12, in guiding face 111 slippage of this pedestal 11, and by the arc structure of this glide plane 1221, adjusting the crevice projection angle of these light source modules 12, so as to solving ray cast that micro-projection arrangement 1 produces on the screen, the problem of Light distribation inequality can be caused.
