Description
Technical field
But the present invention relates to a kind of liquid crystal projection apparatus of horizontal-vertical double-purpose, refer to especially a kind ofly be assembled on second housing by first housing, and the changeability in the assembling orientation of first housing, make liquid crystal projection apparatus have the function of horizontal-vertical double-purpose.
Background technology
The pattern of general liquid crystal projection apparatus is horizontal or vertical, and wherein horizontal liquid crystal projection apparatus can only use in horizontal mode, and can not use in vertical mode, in the same manner, vertical liquid crystal projection apparatus also can only make in vertical mode and can not be used for horizontally, so that liquid crystal projection apparatus has the restriction in the use.
As Fig. 1, Fig. 2 is existing horizontal liquid crystal projection apparatus, wherein the housing 10a of this liquid crystal projection apparatus is integrally formed, and there are a lamp module 20a, two array lens 22a and a ray machine body 30a to be assembled on this housing 10a, this ray machine body 30a includes an optical module group 31a, three image changing device 32a and a projection lens 33a, make the light of the bulb 21a of this lamp module 20a behind described array lens 22a, be projected to this optical module group 31a and described image changing device 32a again, project image via projection lens 33a at last.Long limit and the broadside of wherein said array lens 22a and described image changing device 32a have certain ratio, as 4: 3,16: 9,15: 9 etc., and when described array lens 22a, image changing device 32a are assembled in this housing 10a, assemble on it with corresponding long limit and broadside, the drive circuit board that other has a lid and is assembled in this lid upper surface is arranged at the upper surface (figure does not show) of this liquid crystal projection apparatus with this horizontal liquid crystal projection apparatus of control.
Above-mentioned existing horizontal liquid crystal projection apparatus still has following shortcoming:
1. limit to some extent and when needing horizontal liquid crystal projection apparatus uprightly placed, the image that it projected and original image differ an angle of 90 degrees, are difficult to allow the audience watch when the space.
2. when the horizontal liquid crystal projection apparatus of finishing when existing assembling was placed in vertical mode, described array lens 22a was difficult for revolving and turn 90 degrees, with corresponding to this image changing device 32a that has rotated.
3. the long limit of this image changing device 32a pattern (as Fig. 3) that is provided with wire joining 34a is fit to be connected the drive circuit board of horizontal liquid crystal projection apparatus, reason is that the position of this wire joining 34a is towards this drive circuit board, but the minor face of this image changing device 32a has the pattern (as Fig. 4) of wire joining 34a to be not suitable for being connected horizontal liquid crystal projection apparatus, reason is that the position of this wire joining 34a and the link position of this drive circuit board differ 90 degree (figure does not show), thereby needs the liquid crystal projection apparatus of two kinds of patterns of design.
The utilization of the present invention research and binding isotherm, but design rationally a kind of and effectively improve the liquid crystal projection apparatus of the horizontal-vertical double-purpose of above-mentioned shortcoming.
