INSTRUCTIONS: [Technical Field] The present invention relates to a light-emitting diode lamp with a heat-dissipating agricultural device. [Prior Art] As a new generation of light source, the light-emitting diode light source can not replace the traditional incandescent lamp on a large scale, but it has the advantages of long working life, energy saving and environmental protection, and is generally favored by the market. At present, the module consisting of a light-emitting diode can generate a high-power, high-brightness light source, and thus will replace the conventional light source such as a conventional incandescent lamp, and become a main light source that meets the theme of energy conservation and environmental protection. ... However, with the work of the light-emitting diode or its module, the heat generated by it is getting larger and larger, and the right-handedness is large, and the light-emitting diode lamp with relatively small volume is more difficult to distribute. Go out. , and the nine-in-one polar body still has a large political,, and technical neck, which is also the key to the most difficult breakthrough in the current high-power, market-oriented market. w redundant, one pole body lamp, because the light-emitting diode has a polar body in the body of the light-emitting diode usually: =; degrees, and the light two makes the illumination of the lamp _ limit, ❹m straight on the circuit board, [ SUMMARY OF THE INVENTION The towel body/two hearts have a feast for this, it is necessary to provide a kind of light-emitting diode lamp with good heat dissipation. a large light-emitting diode lamp, a substrate and a substrate formed on the substrate: a heat sink having a heat-transfer body formed on the substrate and having a lateral shape formed in a moon shape, and the heat conductor is longitudinally viewed on 200923249 The twist gradually decreases along its end to the other end. The body of the body is equipped with a high thermal conductivity on the heat sink. The heat dissipation of the first diode module can effectively solve the high power illumination: the polar body: the heating problem. The tilting and triangular cross-section of the heat conductor can form a certain "angle" of the light-emitting diode module and the horizontal plane on the surface of the heat-conducting body without increasing the number of light-emitting diodes, thereby increasing the angle of the lamp. 'Increase the illumination area' and at the same time also meet the needs of the user-specific illumination angle. [Embodiment] In the present invention, the light-emitting diode lamp of the present invention comprises a heat sink 1〇 placed in the political heater A heat conductor 2 is attached to the heat conductor and the light emitting diode module 30 is attached to the heat conductor.

The polar body module % keeps working within its allowable temperature range. 散热器 The heat sink 10 includes a substrate 12, a plurality of first heat dissipation fins 142 extending downward from the bottom surface of the substrate 12, and a top surface of the substrate 12 The plurality of second heat dissipation fins 144 are formed to extend upwardly. The substrate 12 has a substantially rectangular block shape with two longitudinally opposite long sides and two laterally opposite short sides. The position of the substrate 12 opposite to the outer edge of the heat conductor 20 Opening a plurality of first through holes 124' The hole 124 is used for mounting the heat conductor 2 on the substrate. A plurality of second through holes 125 are defined around the first through hole 124, and the first through holes 125 are used for fixing the fixing member (not shown). The first heat dissipating fins 142 are perpendicular to the substrate 12 and extend in parallel along the longitudinal direction. The height of the first heat dissipation fins 142 of the first 200923249 is directed to the sides of the substrate 12 along the intermediate position of the substrate 12. Gradually reduce the shape (see Figure 4). The bottom end of the m H u 10 is arced. • The top surface 144 of the substrate u is perpendicular to the substrate 12 and is located on both sides of the substrate 。. The green door to the side of the substrate 12 - I埶锗' ° The height of the *, ,, ',,, and 9 pieces 144 gradually decreases. The ==44 and the first heat radiating fin are parallel to each other, and the two phases: The flow path 140 through which the airflow passes is formed, and the long side of the Panmei cup 12 is parallel. The substrate i2 /, the substrate slit 16 , ! ^ ^ κ, U 稷 two The two opposite μ 16 extend along the square south & substrate 12 perpendicular to the first heat sink fin 142 and cut the second direction 142. In the two slices 144 and the portion The first fin and the fin 149 ^ are further provided with a plurality of grooves 18 for cutting the first diffuser (4) on the bottom surface of the soil plate, the grooves (7) extending along the slit, and each groove 18 is golden The direction of D is extended in the yin η/Γ—the direct connection of the tangent σ 16. =: The number of the grooves 18 is less than the tan... logarithm, and each phase is 1 W—the trench 16 is provided with a trench 18. 2G is placed on the top surface of the substrate 12. The heat conductor and the material of thermal conductivity such as copper, aluminum < Between the two are a heat-conducting block separated from the heat sink 10, it is understood that the heat-conducting body can be The top surface of the substrate 12 of the heat sink 10 faces; the second heat body, which forms an empty space therein: the second S' can change the phase of her phase: the amount of two charges; as the liquid in the liquid, the use of liquid Zhao Zhiyi 1 hot ¥ official, Soaking plates, etc. The heat conductor 20 has only a truncated shape, and the heat conductor 2 extends along the substrate. Thermal conductor 2. The top 21 and the second _14=: 200923249 are in the middle of the top surface of the substrate 12. The heat conductor 2 is horizontally symmetrical, and the top # 21 is symmetrical, so that the two side faces of the heat conductor 20 form an inclined surface having a certain angle with the top surface of the substrate 12. A plurality of mounting holes 2G1 are formed on both sides of the guide body for mounting the illuminator 30 thereon. The corresponding substrate 12 on the outer edge of the heat conductor 2Q is further provided with a plurality of third through holes 2〇5 for mounting the heat conductor 2 on the political heat. The height of the heat conductor 2 is gradually decreased along the rear end 23 toward the front end 22 thereof, so that the top end 21 of the heat conductor 2 () forms an angle with the top surface of the substrate 12 in the longitudinal direction (refer to the figure). The sheet 144 is placed on both sides of the heat conductor 20. The LED module 30 includes a plurality of strip-shaped circuit boards 31, each of which is provided with a plurality of light-emitting diodes. On the two sides of the heat conductor 2. It can be understood that the road plate 31 can be replaced by a private board of the same name, and the light-emitting diodes 32 can be arranged in a matrix on the whole circuit board. When the light-emitting diode lamp is assembled, the heat-dissipating body 2 is placed on the heat sink 忉: the top surface of the substrate 12 'the circuit board of the light-emitting diode module 3 置于 is placed on both sides of the heat conductor 20 . Referring to FIG. 4 and FIG. 5, when the LED device is in operation, the heat generated by the first diode module 3 can be transferred to the substrate 12 of the heat sink 1G by the heat conductor 2, so that The light-emitting diodes are gathered near the group 30. Finally, the first and second heat-dissipating Korean films 142 are convected by natural air. 144 dissipates heat into the surrounding air. In this embodiment, a portion of the cooling air may flow along the flow path 140 between the first and second (four) sheets 142, 144 and the two short sides of the substrate 12 The direction flows out, and another '= airflow flows along the slit 16 and the groove 18 and flows out from the two long sides of the substrate 12. Thus, the cooling airflow will flow out in four directions and take away the light-emitting diode module 20 to work. The heat of the slit 16 and the groove 181 greatly enhances the air convection between the heat sink fins 14 of the heat sink 1 and the heat dissipation of the small heat sink HH. Therefore, the heat sink iq does not increase the heat density of the heat sink. Under conditions, it has higher heat dissipation efficiency. The invention combines the high-efficiency heat conduction performance of the heat conductor 20 to solve the heat dissipation problem of the light-emitting diode lamp. Nine because the circuit board 31 disposed on the substrate surface of the guide body 2 + + + (4) and the heat dissipation angle thereof can be directed to the light of the light-emitting diode 32, such as "the side is expanded" and thus toward the heat sink 10 : The: the shot area increases. Compared with the illuminating: the polar body 32 is horizontally disposed on the board 12, in the illuminating diode 32, the illuminating diode 32 of the illuminating diode 32 is not included in the 'high 20 in the vertical direction' hoarding In addition, since the heat exchanger 20 22 ^ ^ light 舻 π 2 邛 blade of the air passage plate 31 is upwardly convex, the emission angle can be made to the direction of the arrow of FIG. 5 as compared with the horizontal setting. The irradiation area is increased to meet the lighting needs of the corpse at this angle.
