[Prior Art] • With the advancement of science and technology, from the development of general tungsten filament lamps to the current Cold Cathode Fluorescent Lamp (CCFL) and Light Emitting Diode (LED), It is developing in the direction of volume reduction and flattening. At present, the CCFL can hardly shrink because of the volume, and the CCFL will increase to 600 volts, and the CCFL will cause mercury pollution, which will be banned in some countries. LEDs have many features such as environmental protection, high brightness, power saving, and long life, so LEDs will gradually replace CCFL. However, today's high-brightness LEDs generate a large amount of local heat. If you want to replace CCFL as a lighting product, you must have a suitable heat-dissipation design. Otherwise, LED lighting efficiency will decrease and life will be shortened. The LED package structure uses the Metal Core Print Circuit Board (MCPCB) as the heat dissipation medium, but the LED cannot be set in a high-density manner. The reason is that the heat dissipation capability cannot be effectively broken. Therefore, the LED heat dissipation is urgently needed in the industry. Overcome the problem.

The outer contour of the portion is substantially cylindrical, and includes a circular extension Γ 2 ′ and a number of fins 214 extending radially outward from the outer circumferential surface of the susceptor 212 . Adjacent fins 214 are routed 216 for airflow. The base j forms a through-connecting portion, i.e., a ring-shaped lower-lower connection is formed on the base 212. The upper connection portion 2124 is connected to the lamp holder/, U-connector, and the lamp holder is a standard member obtained on the market. The three bases are added to the inner wall surface and are uniformly formed along the U8 of the base 212 in the axial direction. The 200907234 recess 218 is for receiving a portion of the heat pipe 27〇. Each heat pipe 270 is of a B-type, including the end of the transfer-heat transfer section 272 extending vertically and extending 2 and - and the first heat transfer section 272 is more than the second heat transfer section -: hot section: 2 is a part of 'the first heat transfer element shown in Fig. 1 = the concave - fixed #2 (10) two condensation section fixed in the heat sink portion 21; the value of the other heat transfer section 272, "S 270" The 埶P 1 knives are shown in Figure 1 as the upper part of the first heat transfer & 272, and the „thermal conduction = the evaporation section of the tube 270. In addition, if the heat pipe (10) is a hot two-conductor, the heat transfer slave 274 is connected with the first: 250, the second heat transfer section is also set to (4), so that the evaporation section of the heat pipe 270 is curved. The evaporation section can quickly transfer the heat from the suction part to the condensation; use: to solve the heat dissipation function of the light-emitting diode. Due to the suction part; :::: The heat generated by the light-emitting diode 110 has a great influence on the heat-dissipating module and the effect of the cow. The following is a better understanding of the components of the heat-absorbing part. The working process of the heat dissipation module. The first heat conduction element 230 is a hollow hexagonal prism structure disposed on the upper surface of the heat dissipation portion 210, and has six outer side surfaces - a cylindrical inner surface 234. On the side 232 of the heat conducting element 230, the three light emitting diodes 110 are arranged in a straight line along the axial direction of the first heat transfer: 23 。. The six grooves 236 are disposed on the first heat conducting element 230. The inner surface 234 extends along the axis direction of the first: special element 230. Each of the grooves 236 ′ and the side surface 232 correspond to each other and is located on the corresponding outer side 232 for three times of the 200907234 light-pole body. Directly below the 110 is used to receive the fixed heat pipe as the upper portion of the first segment 272. As shown above, the heat transfer portion 272 of the heat pipe 270 is partially symmetrically disposed: the groove disposed on the first heat transfer element 23 Inside the slot 236; and the first heat transfer section 272 of the heat pipe Disposed in the recess portion 218 of the heat radiating portion 21〇 "this same way, the second heat transfer section 270 of the official 274 located on the - above the skillfulness conduction member 230, and the second heat conducting element connected 25〇. The second heat conducting element 25G is a hexagonal plate-like structure, which covers an upper surface 252 for carrying three light emitting diodes 110 and corresponding electric boards 120; It is disposed above the first heat conduction element. Three channels 256 are symmetrically formed below the second thermal conduction element 25 = = 254'. The grooves 256 are radially distributed and intersect at a central region of the second thermal conduction = 250. In other words, the channels extend radially outward from the central region of the second member (10), and the angle between the adjacent channels is about 120 degrees. When the second heat conducting element 250 is mounted on the conductive element 230, the channels 256 correspond to the second pass of the heat pipe 270 and the second heat transfer section of the heat pipe 27 is received by the IS. Inside. Thus, the second heat transfer section 274 of the heat pipe 270 is radially distributed within the first heat transfer V element 250. The above-mentioned 'light-emitting diode 11' and the corresponding circuit board 12' are provided with an outer surface ′, that is, a surface condition 第二 above the second heat-conducting element 25 、, and an outer side 232 of the conductive element 230.

When in use, the light-emitting diode no generates light under the control of the circuit board 120, and at the same time, the heat generated by the light-emitting diode ιι is absorbed by the first heat-conductive element 23 of the heat absorbing portion, and the second The heat conducting element 25 is absorbed. The amount of heat absorbed by the first heat conduction element 230 and the second heat conduction element 25 is transmitted to the susceptor 212 of the heat dissipation portion 21 through the heat pipe, and is transferred to the heat sink 214 outside thereof, and the heat is radiated to the outside through the heat sink 214. Go in the environment. Thus, the heat generated by the LEDs 11 can be dissipated into the external environment through the large heat dissipation area of the demon portion 210. In this way, the light diode U0 can be X in the normal temperature range to ensure the lighting effect of the lamp and prolong the service life. In summary, the light-emitting diode lamp of the present invention embeds the heat pipe 27〇 in the base 212 of the heat sink 210, which is beneficial to the heat father change between the heat pipe 27〇 and the heat-dissipation training, and reduces the heat pipe 27〇 , w MW on L,,, & 270, the degree of the dish, and then can make full use of the thermal binary:: 10 generated heat is quickly transferred to the heat sink 2 and then "the heat dissipation module fine heat dissipation efficiency, thus It can ensure that the illuminating one's body 1 1 0 work dry is not extravagant, and ΓΗ1 彳乍 in the positive * Μ degree , circumference, improve the lighting effect of the lamp 0 11 200907234 利申: τ'?
