The invention discloses a heat dissipation device which is used for performing heat dissipation on an LED (Light Emitting Diode) lamp. The heat dissipation device comprises a radiator, a plurality of heat dissipation tubes and a fixing base; the radiator comprises a plurality of cooling fins which are arranged in a stacked mode; the plurality of heat dissipation tubes are arranged in a parallel mode to form a heat dissipation frame; the heat dissipation frame comprises a first frame edge and a second frame edge which are arranged oppositely; the first frame edge is arranged on the plurality of cooling fins in a penetrating mode; the fixing base is fixedly arranged on the second frame edge; the fixing base is used for fixing a light source assembly of the LED lamp; the heat dissipation device also comprises a heat dissipation block and a fan. According to the heat dissipation device, the radiator, the heat dissipation block and the fan are combined with each other and accordingly the produced heat can be transferred onto the heat dissipation block and the radiator through the light source assembly, the heat of the heat dissipation block is emitted to the outside through the fan, and accordingly the heat dissipation performance of the heat dissipation device is improved. The invention also provides the LED lamp.
Description
technical field [0001] The invention relates to the field of lamp lighting, in particular to a heat dissipation device and an LED lamp with the heat dissipation device. Background technique [0002] LED lamps are lamps with LED (Light Emitting Diode), that is, light-emitting diodes as the light source. LED is a solid-state semiconductor device that can directly convert electricity into light. Compared with incandescent bulbs, LEDs have the advantages of lower operating voltage, smaller operating current, better impact and shock resistance, high reliability, and long life. [0003] Existing high-power LED lamps generate a large amount of heat, and the existing heat dissipation devices for LED lamps are not mature enough, have complex structures, and the heat dissipation effect is not ideal, thereby affecting the service life of LED lamps. Contents of the invention [0004] The purpose of the present invention is to provide a heat dissipation device with simple structure an...
