Field of the Invention The present invention relates to a light-emitting diode lamp, and more particularly to a light-emitting diode lamp with a heat device. Yizheng [Prior Art] Compared with the traditional light source, the light-emitting diode has the advantages of light weight, small volume, low pollution, long life, high photoelectric conversion efficiency, etc., and it has been used as a new type of light source. The more you apply to various fields, such as street lights, traffic lights, signal lights, spot lights and decorative lights. Tian, ★ However, the light-emitting diode generates a lot of heat during work. If the heat cannot be dissipated in time, it will easily lead to overheating of the LED, which will reduce the luminous efficiency, even if it is directly burned out. continue working. To this end, the industry uses a heat sink to dissipate heat from the LED. A conventional heat sink generally includes a bottom plate and a plurality of fins formed vertically upward from the bottom plate. The light emitting diode module having a plurality of light emitting diodes is attached to the bottom surface of the bottom plate, and the heat generated during operation is provided by the bottom plate. It is transferred to the fins and then convected through the fins to the surrounding air. In order to obtain a larger overall light intensity output, the light-emitting diodes need to be densely arranged on the bottom plate of the heat sink. However, due to the limited heat dissipation capability of a single heat sink, such a dense arrangement will result in the inability to dissipate the heat generated by the light-emitting diode in time, which may easily cause the light-emitting diode to overheat and affect the luminous efficiency. SUMMARY OF THE INVENTION 6 200928201 In view of this, it is necessary to provide a polar body lamp. A kind of light-emitting diode with good heat dissipation performance, and a light-emitting diode, and the first heat sink and a mounting bottom plate and a plurality of self-supporting plates from the bottom plate. The rotor piece 'the other two sandwiched the first-bulk tube. The heat release & and the plurality of connection between the first heat sink and the second heat sink / / S knows the analogy than the light emitting diode lamp of the present invention by埶管=heatsink: side mounted two second radiators, the first radiator; the pounds are unprofitable, the heat that is dissipated can be transferred to the second radiator by the heat pipe, and then lightly passed through the second radiator The fifth field and the first light are emitted into the surrounding air. Therefore, the second heat sink of the present invention can assist the heat sink to dissipate heat from the light emitting diode, thereby ensuring the normal operation of the light emitting diode. As shown in FIG. 1-2, the LED lamp of the present invention comprises a first heat sink of the light emitting diode module 40 mounted on the bottom of the first heat sink g 1 第. 10 second heat sinks 2 on opposite sides and a plurality of heat pipes 3 连接 connecting the first heat sink 10 and the second heat sink 2 Referring to FIG. 4, the first heat sink 1 is integrally formed of a metal material having good thermal conductivity, and includes a rectangular bottom plate 12 and a plurality of fins 14 formed vertically upward from the top surface of the bottom plate 12. The bottom plate 12 The bottom surface is used for affixing the LED module 4' to dissipate the heat generated by the LED and the heat generated by the crucible to the fins 14. The plurality of trenches 16 are opened 7 200928201 The first heat sink is divided into five groups, and each of the grooves 16 is recessed into the top surface of the bottom plate 12. The plurality of fins 14 of the five sets of fins 14 are cut off and surrounded. A plurality of notches 18 (as shown in FIG. 4) are formed in a peripheral region of the bottom plate 12. The bottom plate 12 defines a plurality of screw holes (not shown) at positions corresponding to the notches 18 for screwing (not shown). The illuminating diode lamp is fixed on the bracket (not shown). The two second heat sinks 2 are fixed symmetrically to the first heat sink 1 by heat pipes 3 参阅 as shown in FIG. 2 and FIG. 5 '. Each of the second heat sinks 2 is formed by stacking a plurality of parallel fins 22 in series, and the adjacent fins 22 are shaped The air supply is provided with a gap. The fins 22 of the second heat sink 20 are sighed along the groove 16 (ie, parallel to the plane of the bottom plate 12 of the first heat sink 10). Each of the fins 22 has a rectangular shape. The top and bottom sides of the bottom portion of the JX extend inwardly into the four buckles (not labeled) to fasten the adjacent fins 22 and consolidate the Han #22 into a whole. Each fin > The middle part of 1 22 is provided with a plurality of mutually spaced perforations 24 for the heat pipe 3 to be pierced. The inner edge of each perforation 24 弯 is bent horizontally inwardly to form a ring-shaped hemming%, which is sleeved on the heat pipe to heat the officer 30. Contact area with the second heat sink 2. The length of the fin 22 is equal to the length of the bottom plate 12 of the first heat sink 10, and the height thereof; the height of the heat pump 10 is 'by' Disperse 20, placed on the heat pipe 3〇 and fixed to the sides of the first radiator 1〇; the top P will be /, the top of the political heater 10 is substantially flush, the lower part of which exceeds the bottom plate 12 and is located at the A lower side of a heat sink 10 (as shown in Figure 5). Ίο Λ"! and refer to _ 4, the heat pipes 3 容 are respectively accommodated in the first radiator / groove 16. Each of the heat pipes 3 is flat, and the middle portion is embedded in the bottom plate 12 of the 200928201, and the two ends extend beyond the first heat sink 10 and are respectively inserted into the through holes 24 of the second heat sink 20 to The heat absorbed by the bottom plate 12 of the first heat sink 10 is transferred to the second heat sink 20. As shown in FIG. 2 and FIG. 3 , the LED module 40 is mounted on the bottom surface of the first heat sink 10 , and includes a rectangular circuit board 42 and a plurality of LEDs arranged on the circuit board 42 . Body 44. The circuit board 42 is in contact with an intermediate portion of the bottom plate 12 of the first heat sink 10, which transfers heat generated by the light-emitting diodes 44 to the bottom plate 12. When the light-emitting diode lamp is used, when the light-emitting diode 44 is energized, the heat generated by the light-emitting diode 44 is conducted to the bottom plate 12 of the first heat sink 10 via the circuit board 42. A portion of the heat is directly transmitted to the fins 14 of the first heat sink 10 and then radiated to the air via the fins 14; another portion of the heat is transferred to the second heat sink 20 via the heat pipe 30, which is passed through the second The fins 22 of the heat sink 20 converge into the surrounding air. Since the fins 22 of the second heat sink 20 are spaced apart from each other, the air can sufficiently carry out the flow of 13 between the gaps and quickly remove the heat of the second heat sink 20, so that the entire light-emitting diode lamp is better. heat radiation. Compared with the prior art, the second heat sink 20 of the second embodiment of the present invention can assist the first heat sink 10 to dissipate heat, which dissipates the heat that the first heat sink 10 cannot dissipate in time to the outside air, thereby ensuring the light emitting diode. The normal operation of the body 44. The second heat sink 20 can sufficiently utilize air convection as compared with separately increasing the volume of the heat sink, so that the heat dissipation efficiency is greatly improved. At the same time, since the second heat sink 20 is fastened by the stacking of the fins 22, the number of the fins 22 can be adjusted according to the heat dissipation requirement of the LED module 40, so that the effect of the second heat sink 20 is maximum. 9 200928201 • In addition, because the heat pipe 30 heat transfer is not oriented, the second second heat sink 2〇 is configured to be flexible and can be adjusted according to actual needs.
