As shown in FIG. 4, the fan 15A is disposed on the base 132, and the heat dissipation fins 134 surround the fan 15. (When the fan 150 is turned on, the gas convection in the accommodation space 110a is more vigorous, so that the light is emitted. The polar body lamp 100 can be operated at a lower temperature. It is noted that in the present embodiment, the fan 15A and the light emitting diode light source 120 are respectively disposed on both sides of the base 132. [Third embodiment] 5A and FIG. 5B are schematic diagrams showing relative positions of a fan, a control circuit, a heat sink, and a light-emitting diode light source according to a third embodiment of the present invention.

As can be seen from the ® 5B, the second recess 130b not only allows the volume of the cartridge to be further reduced, but also allows the fan 15G to be closer to the heat sink 130 for better heat dissipation. In view of the above, the various components in the LED lamp of the present invention can be used with other rhymes, and the above-described embodiments of the present invention define the arrangement of the components. In summary, the present invention utilizes the heat dissipation built into the interior of the LED lamp to dissipate heat, and effectively maintains the operating temperature of the LED lamp in a tolerable range, thereby enhancing illumination. The service life of diode lamps. Although the present invention has been described above by way of a preferred embodiment, it is not intended to limit the invention, and it is to be understood that those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
