Abstract
The invention discloses an LED bulb which comprises a lamp holder, a lampshade, a first radiator and an LED lamp bar, wherein the LED lamp bar is arranged on the first radiator, and the first radiator and the LED lamp bar are accommodated in the lampshade. The LED bulb is characterized by further comprising a second radiator which is connected with the first radiator and positioned outside the lampshade. Therefore, the invention effectively conducts and disperses the heat generated by the LED during working and greatly improves the heat radiating efficiency of the LED bulb.
Description
Technical field
The present invention relates to a kind of lighting device, relate in particular to a kind of LED bulb.
Background technology
LED, it is light emitting diode, owing to aspect the key technical indexes such as energy-conservation, life-span length, no stroboscopic, brightness is strong development at full speed being arranged, be widely used in multiple occasions such as Landscape Lighting, large screen display, and will have entered the general lighting field on a large scale in recent years.Along with increase, the quantity of heat production of LED power are too much, bad if heat dissipation problem solves, heat concentrates in the small-sized chip, then can faster devices wear out, and reduction of service life, even cause chip to burn.At present, the LED bulb mainly comprises lamp socket, lampshade, the radiator that is connected with lamp socket, is arranged on LED and lamp housing on the radiator in the prior art, wherein radiator all is placed in lamp housing and the lampshade sealed space with the LED that is arranged on the radiator, this LED bulb is placed in the environment of sealing owing to radiator, therefore cause radiator heat-dissipation efficient low, can't conduct the heat that is produced when evacuating the work of LED lamp timely and effectively, cause accumulation of heat have a strong impact on the LED lamp lighting hours and service life problem.
Summary of the invention
Technical problem to be solved by this invention provides the higher LED bulb of a kind of radiating efficiency.
For achieving the above object, the technical solution adopted in the present invention is: a kind of LED bulb, comprise lamp socket, lampshade, first radiator and LED lamp bar, described LED lamp bar is installed on described first radiator, described first radiator and described LED lamp bar are placed in the described lampshade, it is characterized in that: described LED bulb also comprises one second radiator, and this second radiator and described first radiator are connected and are positioned at the outside of described lampshade.
Preferably, described second radiator is cylindric, this columned second radiator along the circumferential direction at interval be provided with fin.
Preferably, described second radiator is connected by screw with described first radiator.
Preferably, be provided with one the 3rd radiator between described second radiator and described first radiator.
Preferably, the cross section of described the 3rd radiator is circular.
Preferably, be provided with conducting resinl between described first radiator and described the 3rd radiator.
Preferably, be provided with conducting resinl between described second radiator and described the 3rd radiator.
Preferably, described lamp socket, described first radiator, described second radiator and described the 3rd radiator are connected by screw.
Preferably, described lampshade is a glass lamp shade.
Compared with prior art, the invention has the beneficial effects as follows: because first radiator is fixedlyed connected with the 3rd radiator among the present invention, the 3rd radiator is fixedlyed connected with second radiator, after the heat that is produced when therefore the LED bulb is worked is absorbed by first radiator, can conduct to by the 3rd radiator that to be positioned at lampshade outside and be exposed to airborne second radiator, therefore effectively the heat that produces when LED works has been evacuated in conduction, has improved the radiating efficiency of LED bulb greatly.
