Description of the Invention: The technical field to which the invention pertains is a concentrating device for a light source and a lamp thereof, and a illuminating device or the like for a searchlight, a flashlight, and a concentrating device in front of a light source of a projection lamp. [Prior Art] Press, as the pace of technological life comes, lighting fixtures often need better brightness to meet the expectations of the public, but the design of lighting fixtures is fascinating, and (4) thinking about how to increase the power of the light source' However, due to the increase in the power of the light source, although the brightness is required, it also requires a large energy cost (for example, a strong power, a high-power LED, and a light source generator such as a light bulb), and also generates more The heat energy also reduces the service life of the lamps. Therefore, for lighting fixtures, it is necessary to save energy, environmental protection and cost savings, which is the most important direction for the industry. Generally, a luminaire that requires collimated illumination is usually provided with a reflector around a light source generator (light emitting diode or bulb) in order to enable the light of the light source generator to hit the reflector and collimate it out' However, since there is a large opening in front of the reflector, a part of the light of the light source generator is directly diffused in this direction. Therefore, the light is not uniformly collimated, thereby weakening the central brightness of the collimated shooting range in front of the projection lamp. It is the disadvantage of the 201209337 conventional projection lamp; this disadvantage is especially obvious in the design of the light-emitting diode as the light source generator, because the light-emitting diode system is a planar projection light source, so for a single-radiation reflector, It is impossible to direct the parallel projections of light, and the larger the power and diameter of the LED is, the more obvious the disadvantage is, so that the high-power LED is applied to the projection, and the brightness of the center is not The expected ideal 'this is the bottleneck of the industry and has not been able to effectively improve. Such a professional design, in the prior patent of the conventional concentrating device, is described in U.S. Patent No. 6,896,381, which discloses the use of the internal optical totaling and refraction principle of a lens optical element to achieve a small-sized light source (e.g., LEI). The purpose of concentrating light; and, as disclosed in U.S. Patent No. 6,986,593, it is disclosed that a lens is disposed in front of a small-sized light source (for example, an LED), although it can achieve an effect for a small-sized light source, but for a larger-power light source. There is no equal increase in brightness, and the cost of making large lenses is also relatively expensive. At the same time, there is no good breakthrough in the light-harvesting function. 'It is a perfection of the use' should be redesigned. SUMMARY OF THE INVENTION A vehicle capable of placing a luminaire according to the invention has a purpose of concentrating the illuminating light into a central brightness of a small angle range and reducing the front light projection of the light source generator in the reflector to increase the projection range. Energy consumption, the main feature is: at least one reflector cup on one side, can 4 [S1 201209337, the light emitted from the light source generator, part of the light diffused toward the opening of the reflector, can be reflected by the front reflector The collimated shot, effectively reducing the loss of light, and the collimation of the concentrated light, can improve the central brightness of the lighting fixture (the range is also far away), and reduce the energy consumption, so the device is used to project the 'light Flashlights and lighting fixtures not only increase the central brightness, but also have the function of reducing the volume of high-power lamps, which is a feature of the present invention. [Embodiment] In order to enable the reviewing committee to clearly understand the contents of the present invention, only the following description will be used in conjunction with the drawings, as explained later. Referring to Figures 1, 2, and 3, the first embodiment of the present invention includes at least the following main structures: a reflector (10) having a parabola or other aspherical reflection formed therein. The curved surface (11) is such that when the light beam (L) is emitted from one end of the reflecting cover (1), it is emitted toward the other end and the light beam (L) is collimated. A reflector cup (30) is disposed inside the reflector (10) and has the same center line as the reflector (10), and the reflector cups (30) are respectively formed to collimate the beam (L). The outer reflecting surface (31) and the inner reflecting surface (32), and the light incident on the end surface of the reflecting cup (30) and the reflecting cover (1〇) is separated by a distance (h) on the center line, the distance (h) 3 to 10 is the most commonly used, but in fact this distance can be adjusted as needed ' does not need special restrictions; and because of the distance 201209337 (h) setting, can provide the beam (L) after the more In order to be smooth and unobstructed, β is in the case of implementing a lamp as an energy-saving concentrating device. As shown in Figs. 1 and 3, a light-injecting end group of the reflecting cover (1〇) and the reflecting cup (30) is provided. a lamp body (50) having at least one light source generator (5 1 ) on the lamp body (50), the light source generator (5 1) being a light emitting diode (ie, LED), as shown in the present invention As shown, but can also be equivalently replaced by a bulb, when the light beam (L) emitted by the light source generator (5 1) is emitted, due to the surrounding The reflecting surface (11) of the shooting cover (1〇), together with the outer reflecting surface (31) and the inner reflecting surface (32) of the front reflecting cup (30) of the light source generator (51), can make the light beam (L) Collimation is directed toward the other end, effectively improving the disadvantages of using diffused light. The reflector cup (30) may be a light transmissive body. As shown in the second and third figures, a coating layer for reflecting light is respectively attached to the outer side and the inner side of the reflector cup (30). (4 1) to form the outer reflective surface (31) and the inner reflective surface (32); however, the coating (40 or 41) may also be applied to the reflective cup (30) when the actual application changes. The outside or inside of the beam causes the beam (L) to refract and reflect on one side. However, the reflector cup (30) may also be made of polished metal so that its outer side and inner side have a smooth outer reflecting surface (3 1) and an inner reflecting surface (32). The reflecting cover (10) and the reflection The cup (30) has a variety of implementations in combination. As shown in Figures I, 2, and 3, the main purpose is to provide a light-transmitting mask (2〇). The mask (20) can be peripherally The buckle edge (21) is fastened to the outer end of the reflector (10) and the inner side of the mask (20) is engaged with the reflective cup (3〇), and the bonding is a convenient method-; Alternatively, as shown in Fig. 5, the purpose of the design of the present invention can be achieved by engaging in a snap-fit manner. Please refer to Fig. 6 for the combination of another reflector (10) and reflector cup (30). There are several fine connectors (60) between the reflector (10) and the reflector cup (3). The connection, for example, the welding of metal, or the special injection molding, or the simple bonding, but the combination of the technology can be achieved by the existing technical means, which is a matter of using the conventional art, that is, it will not be described. Referring to FIG. 4 again, for a larger power luminaire, two (in this embodiment of the invention) or a plurality of reflective cups (30) (301) can be disposed in the reflector (10) of the present invention. That is, a plurality of reflecting cups (30) (301) are arranged at a certain interval, and have the same center line and overlap with the center line of the reflecting cover (10). Then each reflecting cup (3〇) (3〇1) ) In the space with the reflector (10), the light can be reflected and collimated. Referring to Figures 1 and 6, when the invention is applied to a luminaire, a high-performance luminaire having a concentrating device is formed, that is, behind the reflector (10) and the reflector cup (30) of the concentrating device of the present invention. Adding a lamp body (50) 'The lamp body (50) has at least one light source generator (51)' and the lamp body (50) is assembled on the reflector cover with the light source generator (51) end One end' and the distance between the light source generator (51) and the reflector cup (30) allows the light to be sufficiently emitted and concentrated. This 201209337 luminaire can have a better illumination luminosity β according to the inventor. SUMMARY OF THE INVENTION In actual testing, the center illumination intensity of the concentrating device luminaire equipped with the concentrator of the present invention is about 32. 〇 42 W / Sr, and the test illuminance is about 4271 UX at a distance of 3 m from the light source generator _ heart; The conventional lamp which does not use the present invention has a center intensity of about 27.652 W/Sr and an illuminance of 3291 UX. The present invention has excellent concentrating effect and can effectively improve illuminance. Therefore, in the implementation of the present invention, the following advantages are obtained: 1. The light source concentrating device is disposed in front of the lighting fixture, and the light beam emitted by the light source generator passes through one or more reflective cups. With the reflector of the original # to guide the original obliquely diffused beam, the beam can be concentrated and concentrated in a small angle range, which can be raised without changing the power of the lamp. The central brightness inside, the lighting waste heat, can also save the power and energy, the use value of the production industry. Ming is clearer and not producing ‘cost reduction,
