The above are just a few examples. In fact, if you pay a little attention, you can find that many people are actually applying optoelectronic products to LEDs. Among them, two conventional LED light source structures are exemplified. As shown in the fifth figure, the light emitting body 50 includes two electrodes, and the two electrodes are divided into an anode 52 and a cathode 53, and a function is provided on the cathode 53. To produce a reverse effect, the disc 54 is provided with a LH) die 55, and the disc 54 is also provided with a fluorescent powder, so that the LED chip 55 generates light and transmits the light through the fluorescent reflection. Generate different colors 'Next, a wedge-shaped wiring 56 is installed between the LED die 55 and the anode 52 to connect the two'. A lead wire 57 is connected under the anode 52 and the cathode 53 to connect the power source to make the light emitting body 50 emit light. In addition, the luminous body is covered with transparent resin, and there is a lens resin 51 on it to adjust the range of light output and light can be guided to quasi-parallel light. The lens resin 51 can be set to each of 1233223 shapes to change the directivity. In addition, many are made into a convex shape or a square shape, and their common applications are car brake lights, traffic lights, flashlights, and so on. Another conventional LED light source structure is shown in the sixth figure. The meter body 60 includes a two-electrode anode 63 and a cathode 62. Similarly, a LE: D crystal grain 64 is mounted on the cathode 62, and the anode 62 There is a wedge-shaped wiring 66 on the LED die 64 for the two to be connected to each other. The difference is that a body shell 61 is installed on the light body 60. The body shell 61 is provided with a regular reflection parabolic curve 65, which is a regular reflection The parabolic curved surface 65 is provided to face the light-emitting surface of the LED chip 64, so that the light guide emitted by the LED chip 64 is emitted as quasi-parallel light to make it emit light. [Summary of the Invention] "Technical Problems to Be Solved" I: 11 In order to solve the above-mentioned conventional LED light source structure, an LED light source structure of the present invention is intended to increase the light energy of the luminous body shown in the fifth figure. Designing and making the light more concentrated requires widening and widening the lens resin, and the distance between the light source and the lens resin needs to be lengthened to effectively guide the light to a concentrated state, so the material and cost it needs to lose Relatively, the luminous body shown in the sixth figure, in order to reduce the loss of light and direct the light more concentrated, it must also increase the distance between the light source and the parabolic surface, so the parabolic surface It is necessary to use a large parabolic design, so the material and cost of the required loss will increase relatively, and the above two designs cannot match the design of the light guide plate with a narrow light entrance surface. The conventional LED light source structure applied to the light guide plate of the LCD screen cannot make the LCD screen light and beautiful, so it cannot fully meet the current needs. 1233223 Technical effect "The structure of an LED light source of the present invention is to change the light emitting diode crystals from a conventional horizontal installation method and the light output is a horizontal plane light output, and change it to a vertical installation so that its light output surface is changed to a vertical surface. The light output is because the vertical light output is designed as a half-parabolic light-emitting opening. The opening surface is reduced by half compared with the conventional horizontal light output as a parabolic light-emitting opening. The unchanged light source also makes the light output more concentrated and guided. In order to improve the light output efficiency of the light guide plate, the light output opening of the LED light source structure is adjusted to match the light guide surface of the light guide plate, and the light output opening range of the LED light source structure is adjusted to the light guide plate light surface fan park, so that the light is guided into the light guide plate The range of the light surface, and the light is sent to the light guide plate in a state of quasi-parallel light, so that the light is more effectively used and the loss of light is reduced, and the use of light-emitting materials is reduced. Make the structure of the LED light source more compact 'to match with today's multi-miniaturized products' make the product design more sensitive and charming, and it reduces the structure of the LED light source It can be applied to medical gastroscopes. The reduced LED light source structure can reduce the pain of patients who use gastroscopes to enter the gastroscope. The reduced LED light source structure can also be applied to all original lamps or light sources. In addition, multiple reduced LED light source structures can be used at the same time to make the original lamps brighter. [Embodiment] The present invention is an LED light source structure. As shown in the first figure, the structure of the body housing opening groove 10 is a half-shaped curved surface, and the light emitting opening of the body housing opening groove 10 is An elongated or semi-circular opening surface, and one of the two sides of the body housing opening groove 10 is a curved regular reflection plate 12 ′ and the other side is a flat regular reflection surface 13, and the light emitting diode grain I 〗 It is installed on the plane regular reflection plate 13 in the opening groove of the body shell 1G, but the two-half—parabolic curved surface design 1233223 is obviously more than double the energy concentration of the conventional parabolic curved reflective plate.
