New Description: [New Technology Field] This creation is about a kind of light source simulator. In more detail, it is about a concentrating light source simulator. [Prior Art] With the increasing emphasis on environmental protection and energy conservation, solar cell modules have gradually flourished. However, one of the major problems faced when solar cell modules are manufactured is testing. Since natural light (sunlight) is strong and weak during the day, it is unstable and cannot be controlled by humans. Therefore, the solar cell module after the completion of manufacturing is usually not moved to the outside for testing. The test method is to use artificial light sources indoors to simulate sunshine to obtain product characteristics related to solar cell modules. In order to improve the efficiency of the solar battery module in actual use, a day-tracking device is usually used in combination with the sun-lighting device to allow sunlight to be irradiated to the solar battery module in parallel. However, the sunlight actually has a divergence angle of about 5 degrees. Therefore, how to simulate the above situation during testing is a major issue. [New content] The present invention provides a concentrating light source simulator comprising a light source, an elliptical reflecting mirror, a lens, a cylindrical mirror and a collimating mirror. This light source is used to generate light. The elliptical reflecting mirror has a first focus and a second focus, and the light source is located at the first focus such that light generated by the elliptical reflecting mirror is reflected by the elliptical reflecting mirror. The lens is used to emit light from the elliptical mirror in parallel. The cylindrical lens section has a maximum width, 154594.doc M412365 The cylindrical lens set includes a plurality of cylindrical mirror elements for focusing the light from the lens and then diverging and projecting onto the collimating mirror. The light passing through each of the cylindrical mirror units covers the entire collimating mirror, and the collimating mirror is spaced apart from the cylindrical mirror group by a ratio of 〇〇〇3 to 0.017. The collimating mirror is used to project light rays from the lenticular lens group in parallel on a projection surface. The present invention further provides a concentrating light source simulator comprising a light source, an elliptical reflecting mirror, a lens, a cylindrical mirror group and a collimating mirror. This light source is used to generate light. The elliptical reflecting mirror has a first focus and a second focus, and the light source is located at the first focus such that the generated light is reflected by the elliptical reflecting mirror and then focused on the second focus. The lens is used to emit light from the elliptical reflecting mirror in parallel. The lenticular lens assembly includes a plurality of lenticular mirror units for focusing the light from the lens and then dissipating it. The collimating mirror is used to project light rays from the lenticular lens group in parallel onto a projection surface. The light passing through each of the lenticular elements covers the entire collimating mirror, which of course covers the entire projection surface. The collimating mirror is spaced from the cylindrical mirror group by a distance and the focal length is the focal length of the collimating mirror. In the present invention, by adjusting the maximum width of the cross section of the lenticular lens and the distance between the collimating mirror and the lenticular lens set, the maximum divergence angle of the light projected on the projection surface is about 0.5 degrees. It is the same as the divergence angle of sunlight. The light generated by the concentrating light source simulator can be illuminated in parallel to the module to be tested located on the projection surface. Therefore, the concentrating light source simulator can simulate actual sunlight, and fully meets the test requirements of the high-concentration solar 154594.doc (High C〇nCentrated ph〇t〇v〇ltaic, Hcpv) module. [Embodiment] Referring to Fig. 1, a first embodiment of the present concentrating light source simulator is shown. The concentrating light source simulator 1 of the present invention can be used indoors to simulate sunlight to test solar cell modules to obtain related rrn characteristics, such as current and voltage curves of solar cell modules. However, it can be understood that the concentrating light source simulator 1 of the present invention can also be applied to other places where collimation and uniform light are required, and the applicable field is not limited. The concentrating light source simulator 丨 includes a light source n, an elliptical reflecting mirror 12, a lens 13, a cylindrical mirror group 14, and a collimating mirror 15. The light source 11 is used to generate light. In the present embodiment, the light source 丨j is a one-point light source 'e.g., a xenon lamp, which includes two terminal electrodes 111. The terminal electrodes 11 1 are connected to a power source to supply the voltage and current required for the light source to illuminate. Incidentally, the light source 丨丨 is a gas discharge lamp as long as it conforms to the concept of a point light source, and the light source 丨丨 is not limited to a xenon lamp. The inner side wall of the elliptical reflecting mirror 12 is an elliptical surface having a first focus 121 and a second focus 122. The light source 11 is located at the first focus 121 ′ such that the light generated therefrom is reflected by the elliptical reflecting mirror 12 . Preferably, the elliptical reflecting mirror 12 is attached to a lamp cover. In this embodiment, the concentrating light source simulator 1 further includes a support base for supporting the light source 丨丨. The elliptical reflecting mirror 12 further includes an opening 123'. One end of the light source 11 is fixed to the supporting seat 19 through the opening 123. 54594.doc M412365 This lens 13 is used to emit light from the elliptical reflecting mirror 12 in parallel. The lens 13 can be a convex lens, a concave lens or a spherical lens. In the present embodiment, the lens 13 is a lenticular lens and is disposed outside the second focus 122. That is, the second focus 122 is located between the first focus 121 and the lens 13 such that the light generated by the light source n is reflected by the elliptical reflecting mirror 12 and then focused on the second focus 122, and then The lens 13 is incident on the lenticular lens group 14 in parallel. However, in other embodiments, the lens 13 is a double concave lens and is located between the first focus 121 and the second focus 122 such that the light generated by the light source π is reflected by the elliptical reflector 12 Directly passing through the lens 13 to the lenticular lens group 14 without focusing on the second focus 122. Referring to Fig. 2' at the same time, the first embodiment of the cylindrical lens group in the first embodiment of the present concentrating light source simulator is shown in the front view. The cross section of the cylindrical lens group 14 has a maximum width 〇. The lenticular lens group 14 includes a plurality of columnar mirrors S Μ 该 该 该 该 该 该 该 该 该 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外 之外. Alternatively, the lenticular mirror unit 141 may also be divided into a plurality of concentrating portions (for example, four concentrating portions, as shown in FIG. 4), and the concentrating portions are partitioned by the light shielding material 142. The material of the columnar mirror unit 141 is quartz, and the quartz can withstand high temperatures while maintaining high ultraviolet light transmittance. The columnar lens assembly is substantially rectangular in shape by the array of mirror elements 141 in a (four) array. It is also said that the lenticular lens set 14 has 6 χ 6 cylindrical mirror elements ΐ 4ι, but not limited to (4) 154594.doc M412365. The maximum width D is the diagonal length of the entire cross section of the lenticular lens group 14. In fact, if the lenticular lens group 14 is minimized by a virtual circle, the maximum width D is the diameter of the imaginary circle. Continuing to refer to Fig. 5, there is shown a schematic view of a cylindrical mirror unit of a cylindrical lens assembly in the first embodiment of the present concentrating light source simulator. Specifically, each of the lenticular mirror units 141 is composed of a first lens unit 1411 and a second lens unit 1412 which is located at the focus of the first lens unit 1411. The light is directed by the lens 13 in parallel to the first lens unit 1411 of each of the columnar mirror units 141, and then the light is focused on the focus of the first lens unit 1411, i.e., directly focused on the second lens unit 1412. Eventually the light is again diverged by the second lens unit 1412. The collimating lens 15 is used to project light rays from the lenticular lens group 14 in parallel onto a projection surface 16, wherein the light passing through each of the lenticular mirror units 141 covers the entire collimating mirror 15. In the present embodiment, the collimating mirror 15 is a Fresnel Lens. The projection surface 16 is for placing a module to be tested (for example, a solar cell module) (not shown), and the projection surface 16 is spaced apart from the collimating mirror 15 by an appropriate distance. Referring to Fig. 6', the collimating mirror 15 is spaced apart from the cylindrical lens group 14 by a distance L' which is the focal length of the collimating mirror 15. As can be seen from the figure, the light passing through each of the columnar mirror units 141 covers the entire collimating mirror 15, and the two columnar mirror units ι41 which are furthest apart from the columnar mirror group 14 are projected onto the quasi-lens mirror 15 The angle at which the straight mirror 15 is at the same point is defined as θ, and therefore, the maximum divergence angle of the light refracted by the collimating mirror 15 is also zero. Since the distance L is much larger than the maximum width d of the μ section of the lenticular lens group, the ratio of the maximum width d/the distance l of the cross section of the lenticular lens group 14 is defined as sine, and 〇.2〇 . <0<1. . That is, the ratio of the maximum width D / the distance [between 0.003 and 0.017. In an embodiment, θ = 〇.5. The ratio is 0-0087, D = 17.45 mm, L = 2000 mm, the focal length of the collimating mirror 15 is also equal to 2000 mm, and the area of the projection surface 16 is 3 〇 cm x 3 〇 cm. In summary, the concentrating light source simulator 1 of the present invention utilizes the maximum width D and the distance L' to converge the maximum divergence angle θ of the light projected onto the collimating mirror 15 at 〇.2〇. <0<1. between. Finally, by the conduction of the collimating mirror 15, the maximum divergence angle 0 of all the rays projected on the projection surface 16 is also converged at 0·20° < θ < In other words, since the divergence angle 0 of the light is small, the 'defined light rays are projected in the parallel plane on the projection surface 丨6. Further, the function of the collimating mirror 15 is only to convert the projected light into one direction to match the projection surface 16, and does not change the divergence angle 光线 of the light, which is described in the following description. A schematic view of a second embodiment of the present concentrating light source simulator is shown. Preferably, the concentrating light source simulator 2 further includes a frog mirror 17 and a light concentrating element 18. The filter 17 is located between the lenticular lens group 14 and the collimating mirror 15 for filtering light passing through the lenticular lens group 14 to enhance the performance of the accompaniment. The light homogenizing element 18 (e.g., a sheet or wire mesh) is positioned between the filter 17 and the collimating lens 15 for increasing the uniformity of light on the projection surface 16. In detail, the user can dynamically use the light homogenizing element 18 to block the intensity of the light by the change of the uniformity of the light on the projection surface 16, so that the overall light of the projection surface 16 is uniform, I54594.doc M412365 is uniform. Performance of sex. In summary, in the present creation, the maximum divergence angle of the light projected on the projection surface 16 is Θ, by adjusting the maximum width d of the cross section of the cylindrical lens group 以及4 and the collimating mirror 15 and the column The distance l between the lens groups 14 is such that the maximum divergence angle Θ is about 0.5 degrees' which is the same as the divergence angle of the sunlight. Thus, the light generated by the concentrating light source simulator 1 can be illuminated in parallel to the module to be tested located on the projection surface 16. Therefore, the concentrating light source simulator 1 can simulate actual sunlight and is fully compatible with high concentrating solar energy (High
