LED lamp assembly

Abstract

The invention relates to an LED lamp assembly which comprises a radiator substrate and fins mounted on the radiator substrate, wherein the fins comprise three types namely short-high type fins, short-low type fins and long-low type fins; the short-low type fins are positioned on two edges of the radiator substrate in the width direction; the short-high type fins are dispersed in the middle of the radiator substrate in the width direction; and the long-low type fins are distributed between the short-low type fins and the short-high type fins. The LED lamp assembly is light in weight, has better radiating characteristic, can rapidly transfer heat generated when an LED works to the surfaces of the radiator fins to ensure that an LED chip has lower temperature, improve the luminescence efficiency and prolong the service life; and the structural arrangement of the fins facilitates improvement of the comprehensive effect of natural heat loss through convection.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to an LED lamp assembly. Background technique [0002] In recent years, LED (Light Emitting Diode) has gradually become the most promising green lighting source in the 21st century due to its advantages such as high energy efficiency, long life, good color rendering, quick response, no flicker, and high brightness. And it has achieved more and more extensive and in-depth commercial applications in multiple lighting fields. [0003] In order to meet the market demand for higher brightness lighting products, the input power of LED lamps continues to increase. However, most of the power consumed by high-power LEDs will be converted into heat. Without effective heat dissipation measures, the heat will accumulate on the chip, which will directly lead to a rapid rise in junction temperature. Since LEDs are heat-sensitive devices, working at excessively high temperatures fo...

Problems solved by technology

However, the density of aluminum alloy is also relatively high, and the weight of the produced lamps is still relatively heavy. For large LED lamps with high power and high installation positions such as street lamps, high pole lamps, and industrial and mining lamps, in order to prevent high-altitude In order to avoid the safety hazard of falling objects, it is often necessary to set a safety upper limit for the weight of the radiator

Therefore, while implementing the weight reduction design, the aluminum alloy radiator will lose part of its heat dissipation performance
