In the application of projection, how to effectively absorb the large-angle light emitted by LEDs and increase the brightness of illumination, ―Important = direction, the 6LED light source has a large area, and the illumination angle is also large, making it difficult to use the LED light source as a point source. Generally, the illumination system of the projector can be divided into three categories. The first type is an ultra-high pi.essure (UHP) short arc (aix) bulb, which has a small volume and can be regarded as a light source. This feature uses a reflector to collect the light energy and parallelize or refocus the light into another point, but the disadvantage is that the reflector is bulky and not suitable for small projections. The second type is the LED light as the illumination source, and there is a conventional light collecting element. The light collecting element is slightly acoustic (4) A shape 'this element is straight (four) coffee large angle light collection and parallelization into a usable beam, but this One way to collect only the brightness of a single LED light at a time. The third type is to directly connect an integral 桎 on the LED light. Moreover, with the reflective film at the entrance to assist the light collection into the integration column, this method is only suitable for collecting a single light source. In addition, the light collected by the integration column still needs another light beam to integrate the exit of the column. Projected onto the light valve, the length of the entire system will be very long. SUMMARY OF THE INVENTION 5:286612 Accordingly, an object of the present invention. That is, the light source multi-axis collecting system is captured in a reduced volume space.

" White is a positive lens, but easy to infer, through, see the type and number is not its limit. The lens assembly 4 includes two pairs of real lens groups 4 〇 on both sides of the nail axis 1 and defines each real lens group 40 to have a second optical axis 41 'in this example, the second _ 41 is deviated from the first _ The optical axis 31 is parallel and interposed between the first optical axis and the central axis. Each of the real lens groups 4 () has a second effective focal length of /2, where /2 > 2 乂 'in this example, a real lens The group 4 is illustrated by a third lens 42 having a neighboring light-emitting diode 2 and a fourth lens 43 remote from the light-emitting diode. The four lenses d are all positive lenses. Similarly, it is easy to infer that the type and number of lenses are not limited. In particular, the real lens groups 4 in the present embodiment are respectively molded and then attached to the central axis. 1 use, but this is not a limitation, as is familiar to those skilled in the art, it is also possible to use plastic injection molding to form a real lens assembly 4, or not to use the real lens group 4, which should not be used in this embodiment. The method disclosed in Example 1286612 is limited to the following. The principle of the present invention is described in detail below, in conjunction with the reference θ 2, which is a central axis: a square lens composition, wherein the light-emitting diode 2 and the lens group 3 are less than one. The first effective focal length, therefore, when the light-emitting diode 2 is regarded as the object plane of the T imaging system, the virtual image lens group 3 can be correspondingly opened behind the object surface: a magnified virtual image, and then 'passed through the virtual image lens group 3 Through the real lens group 4G, in general, the virtual image position is 1

The lens composition below is 'in this case, the copying mirror group with the central axis 1 as the axis of symmetry. 'The second optical axis of the real lens group 4〇 is in the opposite direction. In addition, 'Shiyi virtual image lens group 3 and real lens group 敎 Hanwei", with reference _ 3, by losing ", for example, shrink 4, so that the real lens group 40 is close to the virtual lens group 3 to the left, when the sense is about mm ( That is, the 〇8 coffee is reduced to the G axis), the position of the image forming area on the right side of the system will be slowly approached, and the overlap will be more than a part, and finally the purpose of double illumination is achieved. In addition, the overlap of the image planes can be used corresponding to the light valve 5.

For the symmetry, the description of 'Ran' W: and the lens groups 3, 4〇 can also be asymmetrically designed to look at the actual demand and $, and the design of the present invention is described as a two-axis, but can also be extended along this concept into three-axis and four-axis. ·····Infinitely accumulate until the brightness reaches the demand or the volume reaches the maximum limit, and should not be limited to this embodiment: In summary, with the multi-light multi-axis collecting system of the present invention, in addition to inheriting the characteristics of the original single-axis system, the light of the large angle of the light-emitting diode 2 can be collected and converted into small-angle light, or omitted. The volume occupied by components such as the integral tube or the lens array reduces the length of the system, and more preferably, the light source is superimposed, and the light energy is concentrated and projected onto the area of the light valve 5, which not only enhances the brightness, but also moves the real lens group 4 〇 Relative to the distance of the virtual image lens group 3, the projection area is to be overlapped or adjacent to the tile, and the required size of the light valve 5 and the size of the illumination area can be adjusted.
