Problems solved by technology

LEDs are used in daily lighting. In order to meet the illumination requirements, it is generally necessary to concentrate multiple power LEDs on one lamp. Therefore, the heat dissipation of LEDs has become an important factor affecting the use and life of LED lamps, especially for high-power LED lamps. Heat dissipation has become a technical bottleneck affecting its wide application
Existing LED lamps are all passive heat dissipation, that is, heat is dissipated through radiator fins or similar devices. In order to improve the heat dissipation effect, it is necessary to increase the heat dissipation area as much as possible. Complicated, and its cooling effect is not satisfactory
It can be seen that the existing technology has the following disadvantages: complex structure, large volume, poor heat dissipation effect, and short service life

Description

technical field [0001] The invention relates to a lamp radiator and an LED lamp with a fan. Background technique [0002] LED has the advantages of high luminous efficiency, power saving and long life, and its application is more and more extensive. LEDs are used in daily lighting. In order to meet the illumination requirements, it is generally necessary to concentrate multiple power LEDs on one lamp. Therefore, the heat dissipation of LEDs has become an important factor affecting the use and life of LED lamps, especially for high-power LED lamps. Heat dissipation has become a technical bottleneck affecting its wide application. Existing LED lamps are all passive heat dissipation, that is, heat is dissipated through radiator fins or similar devices. In order to improve the heat dissipation effect, it is necessary to increase the heat dissipation area as much as possible. Complicated, and its cooling effect is not satisfactory. It can be seen that the existing technology h...
