Field of the Invention The present invention relates to a light-emitting diode lamp ‘in particular to a light-emitting diode lamp having a heat sink. [Prior Art] As a highly efficient light source, light-emitting diodes have been increasingly used in various fields. However, when a light-emitting diode is used, a large amount of heat is generated, and if the heat is not released in time, the light-emitting diode causes overheating, which leads to a decrease in luminous efficiency. The traditional light-emitting diode lamp includes a plate-shaped heat sink and a plurality of light-emitting diodes on the heat sink-side. The light-emitting diodes are arranged in a plurality of straight lines. When the light-emitting diode is illuminated, it is generated to be radiated into the surrounding air via the heat sink. /, ..., 隹: is 'in order to obtain - higher luminous intensity, the light-emitting diodes:: the middle ground is set in a smaller area' resulting in uneven heat knives on the heat sink, resulting in uneven The accumulation of heat makes it impossible to carry out heat exchange efficiently, and the heat dissipation efficiency of the heat sink of the shovel is; and, because of the light-emitting diode positions, ',,, °. The light emitted by the same side can only be emitted from the side of the radiator to the field, and the illumination angle is limited, and the illumination cannot be illuminated at the same time.

Forming a flat surface and connecting one of the flat surfaces iI 孰 10 10 1 1 形 surface. The length of the heat pipe 20 is opposite to the south of the dispersion 10, and the curved surface thereof is in contact with the surface of the groove 122 of the heat sink 10, and the flat surface thereof is correspondingly flat with the heat sink 10 to completely accommodate the heat pipe 20 in the concave shape. Inside the slot 122. 0 phase moon Please refer to _ 1, the light-emitting diode module 3G is attached to the crying = outer wall m and is in direct contact with the heat pipe 2〇. Each of the light-emitting diode modules; 30 includes a circuit board 32 of a plum-shaped shape and a light-emitting diode 34 mounted in the middle of the circuit board 32. The light-emitting diodes are arranged in the middle of an outer wall 12〇 along the prism body 12, wherein the middle portion of the circuit board 32 of each of the light-emitting diode modules 30 is directly opposite to the flat surface of the heat pipe 2 Contacting, the two sides of the two sides are in thermal contact with the outer wall 12〇, so that the light-emitting diode 34 of the hair-emitting diode module 30 is located directly in front of the heat pipe 2〇, thereby making the light-emitting diode module 30 The heat pipes 2 are symmetrically distributed left and right. As shown in FIG. 3, when the light-emitting diode lamp is used, when the light-emitting diode 1312847........................ The heat it generates is conducted to the middle of the heat sink 10 by the board %. Since the heat pipe 2〇 is directly connected to the light-emitting diode module 3, it transfers heat to the entire heat sink 10 quickly, thereby avoiding the accumulation of heat. A part of the heat passes through the heat pipe 20 and the heat sink 1〇 The outer wall 12〇, = flows into the air around the heat sink 10. The remaining heat is transferred from the inner wall of the heat sink (7) and the fins 14 to the air inside the heat sink 1', which absorbs heat and expands into The hot air with less density, the through-heater through-hole 16 and the upper portion of the gap of the rotor 14 rises away from the diffuser. At this time, the air located at the lower portion of the heat sink 10 passes through the heat sink 1 through-hole 16 and the fin 14 The lower part of the gap moves upwards and enters the inside of the radiator 1; after that, the part of the air absorbs heat again into hot air, thereby continuously achieving air convection, and continuously removing the heat of the light-emitting diode lamp. The heat pipe 2〇 of the polar body lamp is directly in contact with the light-emitting diode mold, and the heat generated by the material can be quickly transmitted to the entire heat sink, thereby avoiding the accumulation of heat, thereby improving the heat dissipation of the radiator.
