Description of the Invention: [Technical Field of the Invention] The present invention relates to an observation system and a projection apparatus, and relates to an asymmetrical lighting system and an asymmetric projection apparatus. [Prior Art] In recent years, 'projection devices have been widely used in conference rooms, large-scale conference halls, cinemas and home theater groups, etc. to provide large-area images. Generally speaking, the more common projections are msa^(Liquid) A crystal display (LCD) projection device, a digital light processing (DLP) projection device, and a liquid crystal on silicon (hereinafter referred to as LCoS). The liquid crystal display projection device passes through the liquid crystal display panel in a transparent manner during operation, and belongs to the penetrating ^1 position optical position device. The liquid crystal projection device is projected by means of optical phase reflection, belonging to the inverse Projector. Among them, the liquid crystal display projection device is made of a linear polarized light. Whether it is a liquid secret display, a digital position, or a liquid crystal projection device, 'In order to make the red light on the screen of the money, the brightness will be evenly distributed in the projection device. Can be sentenced. Since the connection device on the market currently has a display surface of four to three or sixteen to nine, the conventional lens array is designed as a rectangular lens to make the illumination unit (4) After passing through each lens in the lens array, a rectangular beam is formed (the aspect ratio is four to three or sixteen to nine, please refer to "201245765 ΙΑϋ"" as a schematic plan view of the conventional lens array in the third plane. The third plane is a plane of ΧΥ, and the aspect ratio is p:Q), so that the projected area projected on the broken surface is the aspect ratio of Na's actual squash.

The asymmetrical illumination system ι 2 may include, but is not limited to, a light source module no, a lens array 112a, a lens array (10), an illumination lens (4), and a concentrating assembly. The light source module 110 is configured to emit light, and the lens array core and (10) are disposed on the light transmission path, and the backlight is between the lens arrays ma and 112b. In this embodiment, the number of lens arrays included in the asymmetric illumination system may be, but not limited to, two, but the embodiment is not limited to the invention, that is, the 'that is, the asymmetric illumination system 1〇2 The number of lens arrays included in the jin can also be one. It should be noted that when the number of lens arrays is one, the opposite _ faces of the lens array respectively have corresponding curved surfaces. The light source module ιι〇 can selectively emit light, green light or blue light according to different _, 201245765 light source module 110 can include a plurality of light emitting diodes (LED) 'illumination lens Group 7 can be, but is not limited to, a telecentric lens group, but this embodiment is not intended to limit the invention.

It should be noted that the ratio of the length l to the width w of each of the "first lenses" is one to one. The reference to "3B" and "3C" is a cross-sectional view of the second lens array of the "1A" light incident on the first plane and the second plane. As can be seen from "Fig. 3B" and "3C", the first lens 72 in the lens array 112a corresponds to the first lens 72 in the lens array 112b in a corresponding manner. Since the first perspective 2 is a square lens, the incident angle along the first axis (ie, the X direction) is opposite: the effective ray angle θ 透镜 of the lens is equal to the effective ray angle of the incident lens along the second axis (ie, the Y direction) Θγ, which in turn causes light to pass through the lens array n2a and a lens array 112b to form a plurality of uniform square beams 52.

In the present embodiment, the concentrating light is provided, the lens 114 and the third lens 116, so that the first focal length and the first focal length can be adjusted by the relationship and parameters (for example, < and the third lens 116 The relative enthalpy (for example, but not limited to material, relative distance or radius of curvature) is adjusted. Then, please refer to Plant 2A, 2B and 4, and 4Z. Fig. U is a schematic cross-sectional view of a square beam and a rectangular beam. 1. The light emitted by the mode and 1U) (i.e., the red light, the green light, the neon light) is projected through the illumination lens group 7G and projected onto the lens array 112a. In each of 112b, each of the -, -, and brothers 2 is a square beam 52. Since the length L of each of the first lens η in the third plane (ie, the χγ plane) is _--the ratio of the width 1 , the light (4) forms a square beam 52 after each of the first lenses 72 (eg, FIG. 4). Shown). The t-light, and member 108 receives the square beam 52 and adjusts the aspect ratio of each square beam 52 (i.e., L: W = 1:1) to the aspect ratio of the rectangular beam 54 (i.e., the length of the panel 1〇4) See the ratio (ie D: C)) to project to panel 1〇4. Among them, the aspect ratio of the panel office can be, but is not limited to, four to three or sixteen to nine, which can be adjusted according to actual needs. It should be noted that the ratio of the first focal length to the second focal length of the concentrating assembly is related to the aspect ratio of the panel 104. Experiments were conducted below for the above examples. When the first focal length of the concentrating component 1 〇 8 is 34 mm (millimeter ' mm) and the second focal length is 23 mm, the image obtained by the panel 1 〇 4 in the first axial direction (ie, the X axis) (ie, panel 1) The length C of the crucible 4 is 201245765 5.22 mm, and the image obtained by the panel l〇4 in the second axial direction (i.e., the γ-axis) (i.e., the width D of the panel 104) is 3.5 mm. It can be seen from the above experiment that the length ratio of the first focal length to the second focal length is approximately equal to the aspect ratio of the panel 104 (ie, the ratio of the first focal length to the second focal length of the concentrating component is related to the aspect ratio of the panel 1 〇 4) However, this experiment is not intended to limit the invention. The projection apparatus described in the above embodiment is a tactile processing machine, but the present embodiment is not intended to be used in the present invention. That is to say, according to the non-symmetric investment of this issue, the company can cut the New Zealand (Liquid Saga (10) __ Projector ’ LCoS Projector). For a detailed description, please refer to "figure 5a" and "figure map", which are diagrams of the dihedral structure of the first plane and the second plane, respectively, according to the asymmetric embodiment of the present invention. In the embodiment of the prefecture, the 'asymmetric projection device may include an asymmetrical illumination system, the release panel is just outside, and the other may include the spectroscopic unit 202. The polarization polarizing beam splitting unit 2〇2 is disposed between the light source no and the lens _112 such that part of the light passes through the lens array ι2 and the concentrating assembly (10) and is incident on the ]G4. Wherein, the projection device can be a but not limited to a tree-based liquid crystal projector, and the panel 1 () 4 can be, but not limited to, a hybrid liquid crystal panel. In more detail, since the Shi Xiji liquid crystal projector is projected from the panel with a specific polarization state to the panel collapse, the asymmetric surface projection device is asymmetrical when it is a Shiyake LCD projector. The projection device is required to have a polarization polarization of a few 2 〇 2 so that the light emitted by the partial light source 100 passes through the lens arrays 112a, 112b and the concentrating assembly eagle can be projected onto the panel to collapse to generate a picture.
