LED (Light Emitting Diode) lamp

Abstract

An LED (Light Emitting Diode) lamp comprises a heat conduction substrate, a lamp panel, LED light-emitting components, a heat dissipation main body, clamping sliding rails, threaded fasteners and light reflecting components, wherein the heat dissipation main body comprises two radiators; the two radiators are arranged in a manner of symmetric distribution with respect to the central axis of the heat conduction substrate; each radiator comprises a heat dissipation extension plate, a plurality of inner side heat dissipation fins and a plurality of outer side heat dissipation fins. The heat dissipation main body of the LED lamp is provided with the two symmetric radiators, and each radiator consists of the heat dissipation extension plate, the inner side heat dissipation fins and the outer side heat dissipation fins, so that heat, generated by the LED light-emitting components, located on the heat conduction substrate and transferred by the lamp panel can be rapidly dissipated to the external environment in time; the heat dissipation effect is better, and the requirement of the lamp with a big heating value can be met.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to an 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 by the structure of the aluminum ...

AI Technical Summary

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.
