Light emitting diode (LED) lamp

Abstract

A light emitting diode (LED) lamp comprises a radiator, a lamp holder connecting base, a lamp holder, an upper base seat and a lower base seat, wherein the lamp holder is fixed at one end of the lamp holder connecting base, the upper base seat and the lower base seat are respectively in detachable connection with two ends of the radiator, and the upper base seat is connected between the lamp holder connecting base and the radiator. The radiator is made of heat conduction material and comprises a barrel body, a plurality of support components, a plurality of first heat dissipation fins and a plurality of heat dissipation teeth, wherein two ends of the barrel body are open, a plurality of fixing holes are formed in two end faces of the barrel body and are used for being fixedly connected with the upper base seat and the lower base seat, the plurality of support components are evenly distributed on the outer wall of the barrel body, each support component comprises a support plate and a heat dissipation piece, the middle of each heat dissipation piece is in vertical connection with a side edge, opposite to the barrel body, of a corresponding support plate, a clamping groove used for installation of an LED lamp bar and a lamp cover is formed in the outer surface of each heat dissipation piece, the plurality of first heat dissipation fins are fixed on the outer wall of the barrel body, and the plurality of heat dissipation teeth are evenly distributed on two opposite surfaces of the first heat dissipation fins and the support plates. The LED lamp is good in heat dissipation performance.

Description

【Technical field】 [0001] The invention relates to a lamp, in particular to an LED corn lamp. 【Background technique】 [0002] LED is a new type of light source with the most development prospects in the 21st century. The LED industry is considered to be one of the industries with the most development potential in recent years. Everyone expects that LED will enter the general lighting market and become a new lighting source. With the Copenhagen Conference and Low With the launch of the carbon economy issue, LED will generally enter the lighting market, and its economic output value is considerable. [0003] At present, the main bottleneck that restricts the development of LED corn lights is heat dissipation. LEDs are semiconductor light-emitting devices, and semiconductor light-emitting devices will change their characteristics significantly with changes in their own temperature. The increase in LED junction temperature will lead to changes in the performance of each device. ...

[0003] At present, the main bottleneck that restricts the development of LED corn lights is heat dissipation. LEDs are semiconductor light-emitting devices, and semiconductor light-emitting devices will change their characteristics significantly with changes in their own temperature. The increase in LED junction temperature will lead to changes in the performance of each device. attenuation

The theoretical lifespan of LEDs can reach 100,000 hours. In actual use, the junction temperature of LEDs is generally relatively high. Statistics show that 70% of components fail due to excessive temperature. Every time the temperature rises by 10 degrees Celsius, its lifespan will be reduced by half. Moreover, the increase of LED temperature will also have a certain impact on the luminous efficiency and luminous color, such as the red shift of the dominant wavelength, the reduction of phosphor efficiency, etc.
