Abstract

The invention discloses an LED bulb capable of using air convection for heat dissipation. The LED bulb capable of using air convection for heat dissipation comprises a lamp base, a radiator arranged outside the lamp base, an LED mounted on the lamp base and a glass cover covering the LED. The radiator is an aluminum heat dissipation base and a seat of the aluminum heat dissipation base is provided with an air convection groove penetrating the aluminum heat dissipation base to enable the glass cover to be communicated with the outside air. The middle-upper portion of the glass cover is provided with heat dissipation holes communicated with the outside air and the heat dissipation holes are arranged above the LED. According to the LED bulb capable of using air convection for heat dissipation, the bottom of the aluminum heat dissipation base is provided with the air convection groove penetrating the glass cover, and meanwhile, the upper portion of the glass cover is provided with the heat dissipation holes, so that the air flows into the glass cover through the air convection groove in the bottom of the aluminum heat dissipation base of the lamp base and flows into the LED to be in contact with the metal surface, and the air absorbing heat flows out of the glass cover through the heat dissipation holes for forming air convection. Therefore, the LED bulb capable of using air convection for heat dissipation can achieve quick and good heat dissipation effects.

Description

A kind of LED bulb utilizing cross-ventilation to dispel the heat
Technical field
The present invention relates to a kind of LED bulb, particularly relate to a kind of LED bulb utilizing cross-ventilation to dispel the heat.
Background technology
LED bulb has that brightness is high, volume is little, and advantage easy to use, can be applied to multiple occasion.But because the LED heating temp in LED bulb is higher, only dispel the heat by the radiator be arranged on lamp socket in prior art, the effect of its heat radiation is not very good, also temperature is very high often for lampshade, mainly the gas of lampshade forms very high problem, this just for LED bulb result of use, look declines and the impact in life-span is very crucial and fatal, this series products existing needs improvement badly.
Summary of the invention
The present invention is the defect in order to overcome prior art, object is to provide a kind of LED bulb utilizing cross-ventilation to dispel the heat, the LED bulb that this utilizes cross-ventilation to dispel the heat utilizes and offers in the bottom of aluminium alloy radiating seat the air convection groove running through cloche, be provided with louvre on the top of cloche simultaneously, air flows in cloche from the air convection groove bottom the aluminium alloy radiating seat of lamp holder, air flows into LED and contacts with metallic surface, the hot-air absorbing heat goes out to flow out from the louvre of cloche again, form cross-ventilation, radiating effect good fast can be reached.
The technical solution adopted for the present invention to solve the technical problems is: a kind of LED bulb utilizing cross-ventilation to dispel the heat, comprise lamp holder, the radiator be located at outside lamp holder, be arranged on the LED on lamp holder and cover the cloche of LED, described radiator is aluminium alloy radiating seat, base in aluminium alloy radiating seat is provided with the air convection groove running through aluminium alloy radiating seat and make cloche communicate with extraneous air, the middle and upper part of cloche has the louvre communicated with extraneous air, and louvre is located at the top of LED.
Further, described aluminium alloy radiating seat is hollow cylinder, and air convection groove is arranged around circular array bottom aluminium alloy.
In sum, the LED bulb utilizing cross-ventilation to dispel the heat of the present invention utilizes and offers in the bottom of aluminium alloy radiating seat the air convection groove running through cloche, be provided with louvre on the top of cloche simultaneously, air flows in cloche from the air convection groove bottom the aluminium alloy radiating seat of lamp holder, air flows into LED and contacts with metallic surface, the hot-air absorbing heat goes out to flow out from the louvre of cloche again, forms cross-ventilation, can reach radiating effect good fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of LED bulb utilizing cross-ventilation to dispel the heat of the embodiment of the present invention 1;
Fig. 2 is the structure sectional view of a kind of LED bulb utilizing cross-ventilation to dispel the heat of the embodiment of the present invention 1.
Detailed description of the invention
Embodiment 1
A kind of LED bulb utilizing cross-ventilation to dispel the heat described by the embodiment of the present invention 1, as depicted in figs. 1 and 2, comprise lamp holder 1, the radiator 2 be located at outside lamp holder, be arranged on the LED3 on lamp holder and cover the cloche 4 of LED, described radiator is aluminium alloy radiating seat, base in aluminium alloy radiating seat is provided with the air convection groove 5 running through aluminium alloy radiating seat and make cloche communicate with extraneous air, the middle and upper part of cloche has the louvre 6 communicated with extraneous air, and louvre is located at the top of LED.
Further, described aluminium alloy radiating seat is hollow cylinder, and air convection groove is arranged around circular array bottom aluminium alloy.
Above-described embodiment is only some preferred embodiments of the present invention, not limits the scope of the invention according to this, therefore: all various equivalence changes done according to structure of the present invention, shape, principle, all should be encompassed within protection scope of the present invention.
