Detailed ways

The above-mentioned and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

Please refer to Fig. 1 to Fig. 3, the utility model provides an LED lamp, including a lampshade 1, an LED lamp group 2, and a power connector 3; wherein:

Please also refer to FIG. 3 , the lampshade 1 can be integrally made of a material with good thermal conductivity. It is hollow, and a partition layer 11 is horizontally arranged at the middle section of the interior, so as to divide the interior of the main body 10 into a first space 100 and a second space 101 . In addition, a plurality of heat sinks 12 extending outward are provided around the side of the main body 10 to provide heat dissipation.

The LED lamp group 2 is arranged in the first space 100 of the lampshade 1 body 10, and includes a circuit board 20, at least one light emitting diode (LED) 21 arranged on the circuit board 20, a cover device The reflector 22 outside the periphery of the light-emitting diode 21 and a lens 23 mounted on the reflector 22 and for the light-emitting diode 21 to project toward it, and the back of the circuit board 20 is attached to the On the partition 11 of the lampshade 1 body 10, and at the position where the partition 11 faces the first space 100, a first heat conduction block 110 attached to the bottom of the light emitting diode 21 protrudes, so that the light emitting diode 21 The heat generated by itself can be absorbed by the body 10 of the lampshade 1 through contact with the first heat conducting block 110, and the heat is conducted to the heat sinks 12 on the body 10 of the lampshade 1 through the interlayer 11. , so as to release the heat to meet the cooling requirement of the LED 21 .
