LED (Light Emitting Diode) lamp

Abstract

The invention discloses an LED (Light Emitting Diode) lamp, which comprises a lamp holder, an LED substrate and a plurality of LED light sources, wherein the LED substrate is fixedly arranged on the lamp holder; the LED light sources are fixedly arranged on the LED substrate; the lamp holder comprises an outer shell, an inner shell in the outer shell and a frustum-shaped light source mounting table of a hollow structure; the light source mounting table is provided with a large end and a small end opposite to the large end; the large end is fixedly arranged in the inner shell; the small end protrudes out of the inner shell; the outer surface of the light source mounting table is provided with a plurality of radiating columns; the LED substrate is fixedly arranged on the radiating columns; the light source mounting table of the LED lamp has the hollow structure; and the LED substrate is fixedly arranged on the radiating columns on the outer surface of the light source mounting table to increase the radiating efficiency of the LED light source.

Description

【Technical field】 [0001] The invention relates to a lighting tool, in particular to an LED lamp. 【Background technique】 [0002] Sometimes due to the needs of design and light distribution, lamps must use LED light sources, and the number of LED light sources used is large. In this case, the heat dissipation problem of LED lamps is very important. If the heat dissipation problem cannot be solved well, it will inevitably affect The reliability of LED lamps. [0003] When designing the heat dissipation of LED lamps, designers generally add reinforcing ribs directly to the shell of the LED lamp, which can not only achieve the purpose of strengthening the shell of the LED lamp, but also achieve the effect of heat dissipation, but sometimes due to the use of LED lamps When the power of the LED light source is large or the number of LED light sources used is large, such a structure often has an unsatisfactory heat dissipation effect, which will affect the life of the LED light so...
