Field of the Invention The present invention relates to a light emitting diode module, and more particularly to a light emitting diode module including a heat sink. [Prior Art] A Light Emitting Diode (LED)~# semiconductor light-emitting device uses a semiconductor wafer as a light-emitting device to cause photon emission by recombining excess energy in a semiconductor by a carrier. Directly emit white, supervised and other colors of light, the light-emitting diode lighting products are lighting fixtures made by using light-emitting diodes as light sources, widely used in communications, lighting, transportation, outdoor billboards and other fields. However, high-brightness, high-power light-emitting diodes will cause luminous efficiency due to temperature rise, and 4 drops, even causing damage to the components. Therefore, how to keep the operating temperature of the light-emitting diodes is fixed. In order to avoid the above phenomenon, we are in urgent need of solving the problem. At present, the common practice in the #界界 is to attach a heat sink under the polar body board to dissipate its heat. For example, the US t^s 6,517, 218B2 exposes a kind of light-emitting diode module, which: And a plurality of heat-dissipating fins extending from the pedestal, the heat dissipation efficiency of the heat-dissipating device is increased by the heat dissipation efficiency of the heat-dissipating device by the L-chip, and the number of heat-dissipating fins can be increased or increased. 'But the volume of the light-emitting diode module is too large. [Inventive content] 200918806 In view of this, it is necessary to provide a light-emitting diode module having a high heat dissipation efficiency and a compact structure. A light emitting diode module includes a plurality of light emitting diode groups and a heat sink, the heat sink including a base and a plurality of heat sinks formed on one side of the base, the heat sink being embedded on the other side of the base A heat pipe is disposed on the heat conducting plate. The heat conducting plate is disposed on the other side of the base and is in contact with the heat pipe. The light emitting diode group is disposed on the heat conducting plate. The heat pipe is embedded on the other side of the heat sink base and coplanar thereto, so that the overall structure of the light emitting diode module is compact and light, and the heat conducting plate is attached to the other side of the base and is in contact with the heat pipe. The heat concentrated on the heat conducting plate can be quickly transmitted to the heat sink through the base and the heat pipe, thereby ensuring high efficiency of the light emitting diode module. [Embodiment] Referring to FIG. 1 to FIG. 2, a light emitting diode module according to a preferred embodiment of the present invention includes a complex array of LED groups 100 and a heat dissipating device (not labeled) for dissipating heat thereof. . The heat dissipating device comprises a heat sink 220, a plurality of heat pipes 240 attached to the heat sink 220, and a heat conducting plate 260 attached to the heat sink 220 and the heat pipe 240 at the same time. The LED group 100 is closely attached to the heat conducting plate 260 and serves as a light source. The circuit board 120 includes a plurality of circuit boards 120 and a plurality of light emitting diodes 124 (only one is shown) on each of the circuit boards 120. A plurality of holes 122 are formed in the space, and the light-emitting diodes 124 are evenly disposed on the holes 122 of the circuit boards 120 and electrically connected to the circuit boards 120. 7 200918806 The heat sink 22 is made of a high thermal conductivity metal or alloy, such as copper, ф, or copper-aluminum alloy, including a pedestal 222 that is placed horizontally in each shape. One side of the base 222, that is, the bottom surface of the base 222 and the bottom surface of the base 222, the base 222 extends a plurality of fins 224; the top surface of the base 222 is parallel along the longitudinal direction thereof. A plurality of grooved tubes 240 are therein. Each of the heat pipes 240 is disposed in a flat shape, and the top surface 242 and the bottom surface (not shown) opposite to the top surface 242. The heat pipes 240 are welded and fixed to the base 222 of the heat sink 220. The top surface 242 of the heat pipe 240 is coplanar with the top surface of the pedestal 222. The heat conducting plate 260 is rectangular in shape and is made of a metal or alloy of high thermal conductivity such as copper, aluminum or copper aluminum alloy. The heat conduction is provided with a first surface 262 and a second top surface opposite the first surface 262 - again (not shown). The second surface of the V-hot plate 260 is closely attached to the top surface 242 of the heat pipe 240 and the top surface of the base 222. The first surface 262 of the heat conducting plate 2 is closely attached to the bottom surface of the circuit board 120 of the LED module 100 to quickly absorb the heat generated by the LED 124. Referring to FIG. 3 and FIG. 4, when the LED module is in operation, the heat generated by the LED module is first absorbed by the heat conducting plate 260 and the heat pipe 240, and then transmitted to the base 222 of the heat sink 220. Finally, the heat is dissipated along the heat. The heat sink 224 of the device 22 is radiated to the surrounding air to achieve heat dissipation. In this embodiment, a groove 226 is disposed on the base 222 of the heat sink 220, so that the heat pipe 240 can be completely received in the other side of the base 222 and the surface of the side base 8 200918806 222, that is, the base 222 The top surface is coplanar to ensure that the overall structure of the LED module is compact and lightweight; in addition, since the heat conducting plate 260 is closely attached to the top surface 242 of the base 222 and the heat pipe 240, the heat energy concentrated on the heat conducting plate 260 can be The heat sink 224 of the heat sink 220 is quickly transferred to the heat sink 220 by the pedestal 222 and the heat pipe 240, thereby ensuring high efficiency of heat dissipation of the light emitting diode module.
