Description of the Invention: [Technical Field] The present invention relates to a lamp module, in particular to a light-emitting diode car containing at least two independent %; light-pole (LED) lamp particles Light module. [Prior Art] In recent years, the light-emitting diode has gradually become the fastest-developing illuminating element because of its advantages of power saving, long life, low driving voltage and fast reaction rate. With the significant improvement in luminous efficiency, the application range of the light-emitting diode is also becoming wider and wider. For example, a new generation of LEDs can be used as a illuminator in a vehicle's high-mount stop lamp: it can also be used as a vehicle's directional, illuminating, braking, and even A light-emitting element in a headlamp that requires a very high brightness. However, since the light-emitting diode emits light accompanied by the generation of heat energy, the luminous efficiency of the light-emitting diode decreases as the temperature of the environment is increased. Therefore, how to emit the light-emitting diode The generated heat energy is quickly and _ efficiently occluded in the environment in which the light-emitting diode is located, so that the temperature of the environment is not too high, and thus the luminous efficiency of the light-emitting diode is not lowered, and the light has become An important challenge for manufacturers of diodes. For example, in U.S. Patent No. 2/5/4717 M, the illuminating body is provided with a heat dissipating device for dissipating the heat energy generated by the illuminating diode; In the case of the light-emitting diode lamp, the light-emitting diode lamp system comprises a casing, a lens and a plurality of light-emitting diodes. The light-emitting diode system is connected to the heat-dissipating 4 disposed on the casing via a heat pipe, and the heat pipe is disposed. The heat energy generated by the light-emitting diodes can be conducted to the heat sink, and the heat sink can dissipate the heat energy transmitted to the heat sink to the environment where the light-emitting diode lamps are located. However, since the aforementioned heat sink is not directly connected to the light emitting diode (for example, the heat sink in US Pat. No. 2005/0047170 A1 is directly connected to the light emitting diode), it is very close to the light emitting diode (for example, WO). The heat dissipating device in 2006/033998 A1 is disposed on the housing of the light-emitting diode. Therefore, the leg is charged. The thermal energy generated by the light-emitting diode is removed from the light-emitting diode. However, it is not necessarily effective to reduce the temperature of the environment in which the light-emitting diode is located. For example, if the light-emitting diode system is used as a light-emitting element in a headlight of a vehicle, since the headlight is usually located beside an engine room having a temperature of 9 degrees Celsius, even if the heat generated by the light-emitting diode is already It is removed by the heat sink, and the heat sink is still only able to reduce the temperature of the environment in which the light emitting diode is located to about 9 degrees Celsius because it is located in the engine. The light-emitting diode with a rate of 90 degrees Celsius is inevitably drastically reduced. In addition, the light-emitting diode lamp in 20〇6/033998 A1 is located in the housing. Therefore, if any one of the light-emitting diodes is not functioning properly, the maintenance personnel = need to take time and effort to open the lens placed on the casing to replace, and operate the abnormal light-emitting diode Body' If the maintenance staff does not want to be so laborious, then they can choose to replace the entire LED light, but in this case, the cost of '"Dai Teng Tianjiao to repair the LED lights . Further, since the heat releasing device is disposed on the casing, the hair containing the heat dissipating device is included in the predetermined space of the vehicle, and therefore, the heat dissipating device is limited to the predetermined space. The finite volume is not likely to have too much size. The corresponding heat dissipation efficiency of the 'corresponding, ground' heat sink can be greatly limited. SUMMARY OF THE INVENTION In view of the above-mentioned shortcomings of the prior art, the main object of the present invention is to provide a light-emitting diode lamp module having high heat dissipation efficiency and easy assembly. In order to achieve the above and other objects, the LED lamp module of the present invention comprises a first lamp, a second lamp, a heat conduction member and a heat sink, wherein the first lamp system includes a first housing of the thermally conductive bearing portion, a first light-emitting diode disposed on the first heat-conducting bearing portion for emitting a first light, and a first light-emitting diode disposed inside the first housing for reflecting the first light-emitting diode a first reflecting portion of the first light emitted by the polar body, the second granule comprising a second housing having a second heat conducting portion, disposed on the first: the heat conducting portion for emitting the second light The second light-emitting diode is disposed in the second casing to reflect the second light emitted by the second light-emitting diode: the reflective portion is connected to a heat-transfer bearing portion and the first a heat conducting bearing portion for conducting the first yμ two-emitting diode for emitting the energy generated by the lean one, the 筮-also knowing the younger brother-first line, and the political heat element is connected to the The heat conducting member is located at the first, the outside, and is used to absorb and dissipate the heat energyIn the preferred embodiment of the present invention, the heat conducting member may be a tube (h-Pe), and the second heat conducting portion may be a metal bearing. 19941 7 1306064 4 = heat sink system The diverging system having the heat dissipating fins extends to the outside of the first housing: a guide. =-The heat conduction extends to the second M-carved from the */di brother to the heat-bearing portion of the _, "and the extremity 4' for the heat-conducting member to connect the first and second guides to the outside of the body孰.=弟-, the second shell of the second lamp granules 袓...1^, 该, the brother a lamp granules together with the piece and indirectly connected to the ^ ^ by the heat conduction two lamp granules - (four) the younger brother a heat conduction The heat sink is disposed in the front of the vehicle, and the heat sink is disposed in front of the vehicle.

The first lamp particle 21 includes the first casing 21 The first light emitting diode 212, the first heat conducting portion 213, and the first reflecting portion 214, wherein the first light emitting diode 212 is disposed in the first housing 211 for emitting the first light 19941 8 1306064 * <215; The first heat conducting portion 213 is disposed in the first housing 211 for carrying the first light emitting diode 212; and the first reflecting portion 214 is disposed in the first housing 211 for Reflecting the first light ray 215 emitted by the first light-emitting diode 212. Similar to the first light granule 21, the second light granule 22 also includes a second housing 221, a second light-emitting diode 222, and a second heat-transfer bearing portion. The second light-emitting diode 222 is disposed in the second housing 221 for emitting the second light ray 225; the second heat-transfer bearing portion 223 is disposed in the second housing 221 The second light-emitting diode 222 is disposed in the second housing 221 for reflecting the second hair. The second light ray 225 is emitted by the diode 222. In the preferred embodiment of the present invention, the first heat conducting portion 213 and the first heat conducting portion 223 extend from the first housing 21 and the second housing, respectively. 221, the heat conduction member 23 is connected to the first heat conduction bearing portion 213 extending outside the first housing case and the second heat conduction bearing portion 223 extending outside the second housing 221 to conduct the first lamp grain The first light-emitting diode 212 of the second light-emitting diode 212 and the second light-emitting diode 222 of the second light-emitting diode 22 respectively emit heat energy generated by the first light ray 215 and the second light ray 225, and the second light-emitting diode 222 is connected to the heat conductive member 23 for use. To dissipate the heat energy that is conducted to the heat conducting member u. However, in other embodiments of the present invention, the first heat conducting crucible 213 and the first heat conducting carrying portion 223 may also be completely disposed in the second housing 221 of the housing mi, respectively. Accordingly, the other embodiment & heat conducting member 23, it is necessary to penetrate the first housing 211 and the second: 221, respectively, to connect to the first - the true 遐 223. In the preferred embodiment of the present invention, the heat conducting member 23 is a heat pipe; the first light particles 21 together with the second light particles 22 are connected to the fourth (four) carrying portion 213 and the second heat conducting bearing portion 19941 9 1306064 ' It is a headlamp that constitutes a vehicle. Since the heat sink 24 in the LED lamp module 2 of the present invention is not directly connected to the first lamp pellet 21 or the second lamp pellet 22', it is indirectly connected to the first lamp pellet 21 via the heat conductor 23. The first heat conduction bearing portion 213 and the second heat conduction bearing portion 223 of the second light bulb 22, therefore, although the headlights composed of the first light particles 21 and the second light particles 22 must be disposed in a predetermined space of the vehicle, The heat sink 24 can still be disposed in the remaining space of the vehicle 1 outside the predetermined space, for example, in the front bumper 1 of the vehicle 1, in the front fender 12, or near the water tank 13. Since the temperature in the front bumper U, the front fender 12, or the vicinity of the water tank 13 is far lower than the temperature of the engine room adjacent to the predetermined space, the light-emitting diode lamp module 2 of the present invention The heat sink 24 can quickly and efficiently remove the heat energy generated by the first LED 212 and the second LED 222 and further ensure the first LED 212 and the second LED The polar body 222 can operate in a low temperature environment and maintain very good luminous efficiency. In addition, the heat sink 24 is exemplified by a heat sink having heat sink fins. In addition, since the heat sink 24 in the LED lamp module 2 of the present invention can be disposed in the front bumper u, the front fender 12, or the water tank 13, the heat sink 24 need not be limited. The volume of the predetermined space can be larger than the conventional heat sink.
