Efficient heat-dissipation LED lamp

Abstract

An efficient heat-dissipation LED lamp comprises a heat-conducting base, an installing plate body, an LED light-emitting assembly, a heat-dissipation body, a clamp-connecting slide rail, a threaded fastener and a ventilation assembly. The heat-dissipation body comprises two heat-dissipation devices, the two heat-dissipation body devices are symmetrically distributed and arranged with the central axis of the heat-conducting base, and each heat-dissipation device comprises a heat-dissipation extending board, multiple inner side heat-dissipation fins and multiple outer side heat-dissipation fins. The ventilation assembly comprises a ventilation frame, first ventilation fan and a second ventilation fan, wherein the ventilation frame is clamped between the inner side heat-dissipation fins of the two adjacently arranged heat-dissipation devices. The heat-dissipation body of the efficient heat-dissipation LED lamp can rapidly dissipate the heat, transferred by the installing plate body and produced by the LED light-emitting assembly, on the heat-conducting base to the outside environment in time through the two arranged symmetric heat-dissipation devices consisting of heat-dissipation extending boards, multiple inner side heat-dissipation fins and multiple outer side heat-dissipation fins, a heat-dissipation effect is better, and the requirements of lamps having large heat capability can be met.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a high-efficiency heat dissipation LED lamp. Background technique [0002] At present, LEDs, or light-emitting diodes, can directly and efficiently convert electrical energy into visible light, and have a service life of tens of thousands to hundreds of thousands of hours. Lamps that use LEDs as light sources are called LED lamps, which are known as the most commonly used daily lamps for their high quality, durability, and energy-saving advantages. [0003] Usually, the light-emitting components need to be installed on the aluminum substrate, and then the aluminum substrate is installed on the shell of the lamp. The heat generated by the light-emitting component needs to be transferred to the aluminum substrate when it is normally illuminated, and then transferred to the outside air through the casing. In order to achieve the cooling effect. [0004] However, limited b...

Problems solved by technology

[0004] However, limited by the structure of the aluminum substrate, its heat dissipation effect is limited, and it is difficult to meet the requirements of high-power, high-brightness and high-heating lamps. Furthermore, the shell of the lamp is usually made of plastic, and its heat dissipation performance is poor. More The ground plays the role of protection and decoration, but it will affect the heat dissipation path between the aluminum substrate and the outside air, and the heat dissipation effect is poor, especially difficult for high-power, high-brightness and high-calorie lamps.
