Description

A lamp with a portable radiator

technical field

The utility model relates to the lighting field, in particular to a lamp with a portable radiator.

Background technique

Light-emitting diodes (Light-emitting diodes or LEDs) can emit light with a certain brightness, and the brightness can be adjusted by current or voltage. The service life is particularly long. Practice has proved that the life of LED lamps is 20-30 times that of ordinary incandescent lamps, and more than 10 times that of ordinary fluorescent lamps. With the advancement of science and technology and the popularization of environmental protection concepts, LED (light-emitting diode) lighting technology has been widely used. Since LED lights are far superior to traditional lighting products in terms of luminous principle, energy saving, and environmental protection, they are used in many occasions. They all began to use LED lights.

High-power LED lamps have better lighting capabilities. In order to prevent the excessive heat of the nodes of the LED lamp from affecting the life of the LED lamp, a radiator will be installed. The existing radiator generally adopts the structure of setting cooling holes on the side wall of the lamp holder. The cooling effect is poor. In addition, high-power LED lights are mostly made of heat sinks by die-casting technology, which has the disadvantages of high quality and inconvenient disassembly and assembly.
