Problems solved by technology

like figure 1 Shown is the schematic diagram of the LED light power supply assembly with the wind guide cover of the utility model patent No. ZL201120521413.6 previously applied by the applicant, which is fixedly connected with the radiator, the light source substrate and the fan with the radiator as the center. The air guide cover is fixedly connected with the fan or heat sink and the power supply box and the fan or heat sink. The heat sink occupies a large proportion of the volume and weight of the entire LED light power supply assembly, resulting in a large volume of the LED light power supply assembly. Heavy weight, space occupation, and high cost. The LED light source assembly first conducts heat from the light source substrate to the radiator, and then the heat is taken away by the cooling fan. The heat transfer path is complicated.

Description

Technical field [0001] The present invention relates to an LED light power supply assembly; the present invention also relates to an LED lamp including the LED light power supply assembly. 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, multiple power LEDs are generally used in one lamp. Therefore, the heat dissipation of LEDs has become an important factor affecting the use status and life of LED lamps, especially for high-power LED lamps. The heat dissipation problem has become a technical bottleneck affecting its widespread application. Traditional LED lamps are passive heat dissipation, that is, heat is dissipated through the heat sink of the radiator or similar devices. In order to improve the heat dissipation effect, it is necessary to increase the heat dissipation area as much as poss...
