Description of the Invention: [Technical Field] The present invention relates to a lenticular light-emitting diode beam concentrating device, and more particularly to an illuminating system that requires a powerful illuminating concentrated beam and whose area can be reliably controlled, such as a portable light source. Or a stage projection lamp or the like, the light source is a surface light source formed by a light-emitting diode and can be guided by at least two mirrors and a light guide plate of one shape to ensure that the light beam becomes a parallel light beam and achieves a light guiding effect. Good, uniform light quality and high quality. [Prior Art] According to the conventional illumination system, a common device is a device or structure that concentrates a beam or adds a beam or causes a parallel beam, such as, for example, U.S. Patent No. 7,354,178. The light source of the plurality of light-emitting diodes is placed in a flat plate structure, and a reflective structure is formed on the periphery of each light source of the flat plate. The reflective structure is formed into a structure of an elongated notch shape, and the light emitted by the light source is a little in the reflective structure. The light source is reflected as a light source or a light beam. The half angle of the light exit angle is about ±7°, and the optimal light concentration effect is still not achieved. In addition, as in the case of the US Pat. No. 68195005, the light source emits light. The lens is further provided with a lens, and the light inside the lens is refracted and totally reflected to adjust the path of the light travel. For example, in US No. 6,932490, a mirror surface is arranged around a central point light source, and the light travel path is 201005223. At the center, there is a structure of a convex lens to adjust the light at the central position of the entire beam. Lens morphology form of adjustment or readjustment of the structure through the mirror, it still can not shed the light rays to converge around the beam focus' of the radiated light reaches full angle at half maximum of ± 5. Above, there are still those who are necessary to improve. In addition, in Japanese case No. H08-107235, it is provided with a mirror of a concave arc shape on the outside of the bulb, and a lens for projecting the beam is additionally provided at the opening of the large diameter of the mirror, and the lens cooperates with the whole The structure is guided by a single lens, and a light source is further disposed at the center of the concave shape of the mirror. The light source directly emits light in a divergent form toward the mirror, and is guided by the lens. 'In order to make the beam emitted by the lens into a beam, the structure of the single lens is very limited. Another example is the US No. 7111964, which is mainly based on the structure of the previous Japanese case. The body is a light source, and the lens is guided by the light guiding structure, so that the lens directly emits the beam of the flat beam, or the surface of the reflecting surface is combined with the surface of the reflecting surface to enlarge the area of the beam, and the case of the United States No. 6547423 is a single lens with a light source. Design, the design is to adjust the beam through the single lens, the two cases adjust the beam design through a single lens, the ability of the single lens to adjust the beam is very It is limited, and is adjusted by a small area light source or a single light source, which is diffused into a light beam by a central light source. The light guiding angle of each reflection point or light transmission point of the adjustment structure must be very clear. Otherwise, it is easy to make 6 201005223. The effect of the loss of the beam or the inability to maintain the beam is very limited, and the ray is in a parallel state, so the light guide and the concentration are necessary for improvement. [Summary of the Invention]; The film "The Ming people are carefully thought out, and have accumulated many years of experience in various hair, '- polar body related products and technology research and development' finally developed a kind of lens type light-emitting diode beam concentrating device . It is an object of the present invention to provide a lenticular light-emitting diode beam concentrating device, which is mainly provided in a light source of a plurality of light-emitting diodes disposed on a side of a light guide plate to transmit light through the light guide plate. When the emitting surface of the light guide plate is emitted, the parallel light beam of the form of the surface light source is formed, and before the light emitting surface of the light guide plate, the first lens and the second lens '4 lens are sequentially arranged'. (4) The divergence or concentrated guiding light of the two transparent beams makes the beam finally emitted by the light guiding plate more accurate, the parallelism of each light is better, and the light loss is smaller, achieving the purpose of high-quality concentration of the parallel beam. The half value of the light emitted from the emitting surface through the light guide plate is 〇1〇, and the half value of the light emitted by the two lenses is 〇~3 degrees, which is an effective concentration. Another object of the present invention is to provide a lenticular light-emitting diode beam concentrating device, wherein the first lens and the second lens of the concentrating device are both a lenticular lens structure, and are a concave lens and a convex lens. By the combination of the concave and convex, the 7 201005223, which is a beam of light emitted by the light guide plate, is diverged and concentrated, and the area and concentration of the light beam are readjusted twice or more to achieve the purpose of focusing the quality of the beam. Another object of the present invention is to provide a lenticular light-emitting diode beam concentrating device, wherein the first lens and the second lens of the concentrating device are in the form of a convex lens structure, and the two lenses are matched to be emitted by the light guide plate. The parallel beam simultaneously diverges and concentrates the beam, and re-adjusts the area and concentration of the beam twice or more to achieve high-quality concentration of the beam. ❹ 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施When the invention is in-depth and specific, the invention is not the only embodiment. As shown in FIG. 1 , the present invention is a light source having a plurality of light-emitting diodes. The light source 1 〇 is disposed on a light guide member of the surface guide light (4), and a side edge is formed on the end surface of the light guide plate 20 - An emission surface for the light source (10) to emit light (10) = a front surface of the emission surface 21 is sequentially provided on the path through which the light 100 passes, and a second f lens 30 and a second lens 4 are disposed, and the light (10) passes through the first lens. The first lens 4〇4 is adjusted by one or more light guiding paths to uniformly distribute the parallel light beam with high illuminance quality and high illuminance quality, wherein the half-value full-angle of the Guhai light guide plate 2 is emitted by the emitting surface 21 Within the range of 〇ι 〇 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Inside the housing 50, the housing 50 has an elongated hollow chamber 51, which is a recessed-shaped receiving space, and the opening of the chamber 51 is for emitting light 100, and the chamber The chamber 51 is closed in three sides, and the light source 1 〇 and the light guide plate 2 are sequentially accommodated from the inner opening. The first lens 30 and the second lens 4 are connected to each other; and the housing 50 is further provided with a power supply chamber 52 adjacent to the chamber 51 for accommodating the power source 60 in the form of a battery, and is connected to the outside of the power supply chamber 52. The switch 53 is provided for the user to control the switch light source 1 。. A light blocking member 7 is further disposed between the light guide plate 20 and the first lens 30, as shown in FIG. 3, the light blocking member 70 has The light-transmitting portion 71 of the center and the light-shielding portion 72 around the light-transmitting portion 71, the light-shielding member 70 is made of a material that is opaque or light-transmissive, and the light-transmittable material can be glass. Structure or acryl or other transparent structure, the opaque material may be a dark plastic enamel material or an opaque metal or non-metal material, the opaque portion π is a blackened form, that is, The black paint is applied to block the light, or directly made of an opaque material, and the transparent portion 71 can maintain a transparent glass shape, or can be directly hollowed out for the light 100 to pass through the 'effective beam. When a lens 3〇 and the second lens 40 are adjusted and calibrated by the two lenses 30 and 40 The beam designer who can achieve the ancient quality and high precision. As shown in Fig. 2, the structure of the light guide plate 20 is integrally formed into a square 9 201005223, and the light is emitted from the light guide plate 20 The end face of the crucible is an emitting surface 21, and the emitting surface 21 is disposed on the surface of a total reflection layer 22, and the end surface of the total reflection layer is adjacent to a reflective layer 23, which is away from the total reflection layer. The surface of 22 may be provided with a slope or protrusion reflecting structure so that the light guided by the total reflection layer 22 to the reflective layer 23 may be emitted from the emitting surface to be a parallel beam. The first lens 30 and the second lens 40 can be the same as the structural shape of a lens. As shown in FIG. 4, the first lens 30 is in the form of a concave lens to form the light 100. Here, the parallel beam forms a slightly divergent angle to the second lens 40, and is concentrated so that the respective rays 100 of the parallel beam are emitted by the light guide plate 20, and the beam angle collimation (c〇uimated beam angle) It differs from the optical axis by about ±3. Within the range, after passing through the light guide 5 and the second lens 40, the light can be reduced to the soil 1. When the light 100 is emitted from the light guide plate 20, the full value of the half value is in the range of 〇 to 〇, and after the light is guided by the first lens 30 and the second lens 4, the half is full. The structure of the first lens 30 of the preferred embodiment is matched with the second lens 40. The first lens 30 in the form of a concave lens has a focal length of π, which is the form of the convex lens. The focal length of the two lenses 40 is f2, wherein if n=_(i/3)f2, the distance between the first lens 30 and the second lens 40 is about (2/3) f2, and the light beam is expanded by 3 times, and the light exit angle is The light is reduced to (1/3) of the light exit angle of the original light guide plate 20, and the light intensity of the area 201005223 is also weakened to (1/3). Therefore, the closer the light guide plate 2 is to the first lens 30 and the second lens 40, the better. And by the change of the distance between the first lens 3 〇 and the second lens 4 可使, the projection area of the entire parallel beam can be enlarged, the luminosity density is reduced, and the accuracy of the light exit angle can be improved. The structure shown in FIG. 5 is also obtained. The first lens and the second lens are both structural forms of a convex lens, and the same can be achieved. The function, and by the change of the distance between the first lens 3G and the second lens _, the parallel beam bundle can be concentrated and then diffused to the second lens 4G to form an enlarged area, which is refracted by the second lens 40, and projected The area can be relatively enlarged, and the luminosity is uniformly reduced, and the projected light 100 maintains the accuracy of the overall parallel beam exit angle, and the half value of the light 100 emitted by the emitting surface 21 is 〇ι〇度, the light After passing through the two lenses, the full value of the half value is about 〇] degrees; and the light rays 100 are emitted by the light guide plate 20. The light angle collimation ((7) (1) wall d beam angle) is different from the optical axis. Within ,, after the light guiding of the two lenses, it is reduced to ±0.3. Within the above structure, the following functions can be achieved, including: 1. The projected light beam angle can be kept at the maximum. Optimum state: by sequentially aligning the projection between the first lens 30 and the second lens 40, the parallel beam of the projected light 100 is adjusted twice or more to maintain the optimal light exit angle. It Straightness and light _ can be kept within = °, and the full value of half value can be reduced to (M0 degree to 〇 ~ 3 degrees, so accurate 201005223 degrees, this projection light technology can be applied to the beam of photomicrography The projection request can also be used for a large-scale long-range projection of a searchlight or a portable flashlight. 2. The parallel beam area can vary greatly: From the foregoing analysis, it can be seen that the parallel beam can be projected through the first lens 30. The distance between the second lens 4 and the second lens 4 is adjusted to achieve a change in the projected area. Therefore, the distance between the first lens 3 and the second lens 40 can be fixed in the casing 5 at the time of fabrication, or the foregoing The casing 50 of the crucible is set in a retractable shape, but this part is not the focus of the invention. Therefore, the area of the light guide plate 2 can be directly increased or reduced, and the number of the light source 10 is increased. It can also be increased or decreased relatively, and at the same time, the area of the first lens 30 and the second lens 40 can be increased or decreased, and different fits can be made according to different needs when making the fit. In summary, the 'special design of the Wei-style illuminating diode wire concentrating device in this case has been "having a good job in the industry" should be undoubted, in addition to this '" in the case of the creation of the case revealed The technical characteristics have not been seen before the application, nor have they been publicly used. 'Additional and the fact that the effect is improved as described above. 'The novelty and the progressiveness of the invention are in compliance with the provisions of the Patent Law. Applying for the creation of a patent in accordance with the law, praying for a review and early granting of a patent, it is really sensible. 12 201005223 [Simplified description of the drawings] Fig. 1 is a schematic cross-sectional view showing the overall structure of the present invention. = Figure is a schematic plan view of the large-area end of the light guide plate of the present invention.
