New description: [New technical field] This is a kind of LED lamp structure, especially a kind of LED which is bent on one side of a substrate and corresponding to one of the bending parts. The unit concentrates the brightness of the light on the center of the LED luminaire, and at the same time achieves the effect of wide-angle illumination. [Prior Art] Each light source has its own characteristics. The lamps used at this stage are incandescent lamps, fluorescent lamps, metal halide lamps, electrodeless fluorescent lamps, mercury-free fluorescent lamps, and LEDs for lighting. Emitting Diodes; light-emitting diodes, all have their own unique optoelectronic properties, safety performance, and environmental performance. However, LED lamps have strong potential advantages in lighting applications, and applications and market ratios will expand rapidly, and may replace traditional light sources in the future. With the development of lighting technology, the evaluation of future lighting sources is not only focused on the light effect, but also emphasizes the lighting effect, the comfort of light, the biological effect of light, the safety evaluation of light, and the evaluation of environmental performance and resource consumption. . Compared with traditional white-wound tungsten light bulbs and fluorescent lamps, LED light-emitting diodes are small in size and can be used according to the application object, allowing multiple combinations, low heat generation, low power consumption and long life. In the case of environmental protection, it is possible to recycle waste materials that do not become environmental pollution, etc., which are used to undertake traditional lighting fixtures as lighting fixtures for the next generation. Among them, low heat generation and low power consumption are characterized by its "low voltage" and "low current" operation. M341153 is more efficient due to LED conversion, and consumes one-tenth of the power of the general bulb. The service life can reach more than 100,000 hours, which is at least higher than the hour of the tungsten bulb and 5000 hours of the neon lamp. More than 15 times, after the package is completed, it has the characteristics of shockproof and weatherproof. The new packaging technology can make the product both light and short, and can also improve the disadvantage that the tungsten bulb is easily damaged by running vibration and consumes electricity. It is also relatively low, so the domestic lighting manufacturers are all moving towards the trend of LED lamp groups to replace traditional odont bulbs or tungsten bulbs. Clearly, as shown in Figure 1A, Figure 1A is a schematic diagram of the illumination of a conventional LED lamp set. Wherein, the conventional LED lamp set la is provided with a plurality of LED units 11a disposed on one of the flat bases i2a and located above the same horizontal plane, and the light projected by the plurality of LED units 11a makes the conventional LED lamp set as a whole. The light intensity (brightness) of the central part of la is insufficient to meet the illumination area standard of the general street lamp projection brightness. Please refer to Figure 1B. Figure 1B is a schematic diagram of another conventional LED lamp set. The conventional LED lamp set lb is generally one of the inverted trapezoidal bases 12b' and is inclined upwardly on a slope i21b on both sides of the base 12b, and respectively on the base 12b and on both sides An LED unit lib is disposed on the inclined surface 121b, and the LED units lib on the two inclined surfaces 121b are respectively projected at an angle to be outwardly projected to achieve wide-angle illumination. However, the illumination intensity of the LED unit lib located at the central portion of the pedestal 12b is still insufficient. Although it has the effect of wide-angle illumination, it cannot provide a good illumination area for the central projection portion of the conventional LED luminaire group lb. . Therefore, how to make the light projected by the LED unit can be concentrated in the center of the lamp holder, and at the same time, the function of wide-angle illumination is the main key to overcome. 6 M341153 [New content] The main purpose of this creation is to provide an LED lamp structure in which a plurality of LED units are respectively bent on the two sides of a substrate and corresponding to one of the bent portions, The overlap of light levels is concentrated in the center of the LED luminaire, and at the same time achieves the effect of wide-angle illumination. Another object of the present invention is to provide an LED lamp structure in which a heat dissipation module coupled to the substrate rapidly dissipates heat generated by the LED unit to extend the life of the LED unit. ... For the above purposes, the present invention is to provide an LED lamp structure, which mainly includes: "New Zealand" and a plurality of LED units. The substrate is a gold chip substrate, which further includes a reflective surface and an outer surface. A bent portion is respectively disposed on opposite sides of the substrate, and each of the reflective surfaces is bent at a predetermined angle and corresponds to each other. The LED unit is disposed on the reflective surface of the substrate and is located at a predetermined position of the substrate and the material portion, respectively. The plurality of LED units disposed on the two opposite bending portions are arranged to overlap the brightness of the light at the center of the LED lamp, and have the effect of wide-angle illumination, so that the light refraction efficiency of the lamp structure is further Play to the extreme. [Embodiment] In order to more clearly describe the structure of the 2LED lamp proposed by the present invention, the following will be described in detail in conjunction with the drawings. Please refer to Figure 2, Figure 2 is a three-dimensional sub-section of the LED lamp structure 7 M341153 solution. The LED lamp structure 2 of the present invention mainly comprises: a substrate 21, a plurality of LED units 22, at least one heat dissipation module 23, and a lamp cover 24.

The two sides of the substrate 21 are respectively bent and bent to form a horizontal positive projection area between the two bending portions 213, 213' in the center of the reflecting surface 211 of the substrate 21. 215. The bent portions 213 and 213 on both sides of the substrate 21 can be bent on both sides of the substrate 21 by a folding bed, and folded in the direction of the reflecting surface 211 with reference to the horizontal direction of the substrate 21. Bending a predetermined angle θ1, the preset angle Θ1 can adjust the angle of the bend according to different light refraction requirements, so that the two bent portions 213, 213' respectively have the same light substantially toward the center of the substrate 21. The nickel reflects the angle, and the preset angle 01 is preferably between 10 and 20 degrees. The material of the substrate 21 may be made of iron, copper, aluminum, silver, gold, or an alloy thereof. The LED unit 22 (Light Emitting Diodes) are arranged in an array on the positive projection area 215 in the center of the substrate 21 and the two curved portions 213 and 213, which are common to the reflection surface 211. Since the LED unit 22 disposed on each of the two folding portions 213 and 213' has an illumination angle of approximately 35 degrees to 120 degrees, the LED unit 22 of different brightness can be matched according to the reflection angle, and the illumination color is And the wattage can be adjusted to increase or increase the number of LED units 22 according to different reflection requirements. The heat dissipation module 23 is formed by a plurality of heat dissipation fins 231 and spaced apart by a predetermined distance, and is respectively disposed on the substrate 21 and the two curved portions 213 and 213, and the external side surface 212 shared by the two The heat generated by the LED unit 22 is transmitted by the heat dissipation fins 231 of the heat dissipation module 23 through the substrate 21 8 M341153 and rapidly cooled, and at the same time, the heat dissipation efficiency is improved and the life of the LED unit 21 is prolonged. The heat dissipation module 23 may be made of iron, copper, aluminum, silver, gold, or an alloy thereof. The lamp cover 24 can accommodate at least one set of the substrate 21 therein, and the plurality of heat dissipation holes 241 are disposed on the lamp cover 24, so that the heat dissipation module 23 in the lamp cover 24 can generate heat when the LED unit 22 emits light. The heat dissipation holes 241 are discharged outside the lamp cover 24, and the heat energy generated when the LED unit 22 emits light is rapidly dissipated outside the lamp cover 24 via the heat dissipation holes 241 via the heat convection of the outside air. 4 Referring to Figure 3, Figure 3 is a cross-sectional view of the structure of the LED lamp. The plurality of LED units 22 are disposed on the reflective surface 211 of the substrate 21, and are respectively arranged in an array form in the positive projection area 215 disposed in the center of the substrate 21 and presets of the bending portions 213, 213'. The heat dissipation module 23 is disposed on the outer side surface 212 of the substrate 21 and further integrated into the lamp cover 24, and the substrate 21 and the heat dissipation on the outer side surface 212 are utilized by the lamp cover 24. The module 24 is substantially covered, and the thermal energy generated by the LED unit 22 is discharged outside the lamp cover 24 by the heat dissipation hole 241 provided in the lamp cover 24. The lampshade 24 can be a lamp, a streetlight, a searchlight, and a tunnel light casing, and a plurality of LED units 22 on the substrate 21 are combined to form the LED lamp structure 2 having the lampshade 24. The LED luminaire structure 2 can be one of a tunnel light, a street light, and an illumination lamp. Please refer to Figure 4, which shows the lighting intent of the LED lamp structure. The light is from the substrate 21 and the bent portions 213 and 213 on both sides of the substrate, and the LED unit 22 disposed on the upper side of the substrate 21 is bent by the substrate 21 by the pre-9 M341153 β and the angle 01 to light the substrate. The bent portions 213, 213 on both sides of the 21 are projected and overlapped at a central projection position 3 of the substrate 21, and overlap with the light projected by the LED unit 22 disposed on the positive projection region 215. The illumination brightness area projected by the LED unit 22 of the LED lamp structure 2 is concentrated in the central projection position 3, and the surrounding milk from the central projection position 3 has the LEDs 213, 213 from the LEDs. The unit 22 is overlapped and projected to extend out of the wide-angle illumination area 4 of the central projection position 3, so that the illumination area of the LED lamp structure 2 as a whole is wider. In other words, the LED lamp structure 2 utilizes the bent portions 213, 213' on both sides of the substrate 21 to respectively project the LED unit 22 at a predetermined angle to project a light toward the center of the substrate 21. In order to assist and increase the brightness of the light projected by the LED unit 22 disposed on the positive projection area 215, the brightness of the projection is gradually concentrated from the wide-angle illumination area 4 toward the inner side toward the central projection position 3, so that the positive projection is made. The light projected by the LED unit 22 disposed on the area 215 overlaps with the light projected by the LED unit 22 disposed on the bent portions 213 and 213, thereby increasing the illumination efficiency of the ten-central projection position 3. And the brightness is avoided to avoid the light-scattering loss of the bent portions 213 and 213 on both sides of the LED unit 22 when the LED unit 22 is placed at a wide angle, so as to fully utilize the brightness of the light projected by the LED unit 22.
