Abstract

The utility model discloses an LED (light emitting diode) lamp with a long service life. The LED lamp comprises an LED lamp body, a driving power supply, a heat radiation device and a pedestal; the driving power supply is electrically connected with the LED lamp body, the driving power supply is electrically connected with an external power supply, and the pedestal is arranged on the lower end of the heat radiation device. The LED lamp is characterized in that the heat radiation device comprises a heat conducting sleeve and a heat radiator, wherein the heat radiator is sleeved on the outside surface of the heat conducting sleeve, the LED lamp body and the driving power supply are fixedly arranged in the heat conducting sleeve, the pedestal is fixedly arranged on the bottom of the heat conducting sleeve, and a glass cover is arranged on the top of the heat conducting sleeve. The LED lamp has the advantages that the heat conducting sleeve is used as a casing, so that an existing plastic casing is eliminated, the manufacture cost is reduced, the heat radiation effect is enhanced, and the service life is prolonged.

Description

A kind of long-life LED lamp
Technical field
The utility model relates to a kind of LED lamp, specifically, relates to a kind of long-life LED lamp.
Background technology
LED (Light Emitting Diode, Light-Emitting Diode) is a kind of solid-state semiconductor device that electric energy can be converted into visible light, LED occur early stage, LED is through being usually used in the indicator lamp of various device, but the development along with the LED technology, LED begins to be applied to lighting field, the LED lamp therefore occurred; Because the LED light fixture has the life-span long, the light efficiency height, low-power consumption, energy-conservation, outstanding features such as environmental protection, therefore just be applied to growing field, but LED lamp heat dissipation problem is a factor that limits its faster development always, because if LED lamp radiating effect is not good, too much heat will cause the temperature of LED lamp to raise, the rising of temperature can be accelerated the light intensity attenuation of LED lamp and the reduction in life-span, and present stage is in order to dispel the heat to the LED lamp, mostly adopt metal heat sink to dispel the heat, behind the metal heat sink expanded by heating because volume becomes big, cause lamp body shell cracking, influence service life.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
