LED (light-emitting diode) lamp with radiating function

Abstract

The invention discloses an LED (light-emitting diode) lamp with a radiating function, comprising a lamp cap, a housing, a driving circuit, a vertical-face lamp holder and an LED light source, wherein the vertical-face lamp holder is a hunched geometry table body, an installation seat is formed on the surface of the geometry table body, the LED light source is fixed on the installation seat and is connected with the driving circuit which is installed in the lamp cap, a radiating part is formed below the vertical-face lamp holder and is provided with a plurality of fins, hollow shapes are formed among the fins, the bottom of the radiating part is fixed on the lamp holder, the housing covers the top of the radiating part, and the vertical-face lamp holder and the LED light source are arranged in the housing. Due to the structure, the three-dimensional heat exchange with air from inside to outside can be realized, heat generated during the working of the LED light source and the driving circuit can be diffused outwards timely, the radiating area is increased by more than 1.5 times compared with a traditional radiating way, and the radiating effect is good, so that the service life of the LED lamp can be prevented from being influenced by an overhigh temperature.

Description

technical field [0001] The invention relates to an LED lamp, especially related to its heat dissipation function structure. Background technique [0002] In the prior art, the structure of the LED lamp is as figure 1 As shown, it is mainly composed of a lamp cap 10, a housing 20, a driving circuit 30 and an LED light source 40. The housing 20 is covered on the lamp cap 10, the driving circuit 30 is installed in the lamp cap 10, and the LED light source 40 is installed on the inner side of the lamp cap 10 and is in the In the housing 20 , the LED light source 40 is connected to the driving circuit 30 . When in use, after the power is turned on, the driving circuit 30 controls the LED light source 40 to emit light, and the light passes through the casing 20 to achieve the lighting effect. [0003] After careful observation, it is not difficult to find that because the LED light source 40 of this LED lamp is arranged on a plane, and usually only one LED forms a point light so...

Problems solved by technology

[0005] but, image 3 The heat generated by so many LED lamp boards 60 plus the driving circuit 30 electrically connected with these LED lamp boards 60 in the working process is far greater than figure 1 As shown in the existing planar LED light source 40 and the heat generated by the drive circuit 30 electrically connected to it during the working process, a large amount of heat cannot be diffused outward in time, which directly affects the service life of the LED lamp
