Detailed description of the invention

Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this Utility model.

Referring to figs. 1 through Fig. 2, an embodiment of a kind of LED bulb of the present utility model is proposed, including lamp holder nut, connection Be fixed on lamp holder nut upper end bulb socket 100, be connected to bulb socket 100 upper end be provided with the holder structure of light source post 203, company It is connected to holder structure upper end the footstock enclosing the diffuser 300 being located at outside light source post 203, being connected to diffuser 300 upper end, also wraps Include the driving means being located in bulb socket 100.

Footstock includes being positioned at the cap structure 401 of the boring of diffuser 300 upper end, by cap structure 401 towards downward That stretches may pass through diffuser 300 light source cover 402 covering on light source post 203.

Holder structure includes the lamp holder 201 being connected on bulb socket 100, is extended out upward by lamp holder 201 Light source base 202, the light source post 203 that extended out upward by light source base 202, light source post 203 outer surface is provided with LED light source knot Structure.

Diffuser 300 is between cap structure 401 and lamp holder 201.

Cap structure 401, holder structure, bulb socket 100 are the structure of boring, and cap structure 401 upper end is provided with Top cover through hole 403, light source post 203 upper end is communicated with to the light source post through hole 204 within holder structure, on lamp holder 201 End is provided with lamp socket through hole 205, and bulb socket 100 lower end is provided with bulb socket through hole 101, top cover through hole 403, light source post through hole 204, lamp Block hole 205, bulb socket through hole 101 be interconnected and form vent passages so that outside air circulate and formed can be rapid Take away the air-flow of LED bulb internal heat.So, cool exterior air is the formation of Air Temperature Difference with the hot-air in vent passages And atmospheric pressure is poor thus forms air-flow, the air of flowing takes away rapidly the heat within LED bulb, by spontaneous air stream Moving and take away rapidly heat, outside air carries out quick heat exchange, and radiating efficiency is high.The most novel radiator structure, structure is new Grain husk, and rationally simple, utilize the temperature difference and draught head as power to promote air to flow, form spontaneous air-flow and take away rapidly Heat, radiating efficiency is high, and good heat dissipation effect effectively extends the service life of LED light source.

Holder structure is formed in one the integral die-cast part of structure, and holder structure is made up of heat-conducting metal, and conduction heat transfer is imitated Rate is high, and radiating effect is preferable.

Bulb socket 100 extends upward and can be embedded in lamp socket and driving means being surrounded in case driving means and lamp Holder structure contact and there is the enclosure structure 102 of electric shock electric leakage accident, bulb socket 100 is formed in one structure by insulant Make, so may insure that driving means will not touch the metal parts such as holder structure or lamp holder nut, and driving means Can the most exposed and without wrapping up one layer of insulant, good heat dissipation effect.

Enclosure structure 102 is fixed with lamp holder 201 medial wall by snap fit.

Light source cover 402 lower end is fixed with light source base 202 by buckle structure.

Diffuser 300 upper end is sticked in cap structure 401 lower end, diffuser 300 lower end and lamp holder 201 threaded upper ends Connect fixing.

Diffuser 300 is made up of antifog glass, so, in time in wet environment, diffuser 300 does not haves water yet Mist and affect illumination effect.

The cap structure 401 of this utility model LED bulb, holder structure, bulb socket 100 are the structure of boring, Cap structure 401 upper end is provided with top cover through hole 403, and light source post 203 upper end is communicated with to the light source post within holder structure leading to Hole 204, lamp holder 201 upper end is provided with lamp socket through hole 205, and bulb socket 100 lower end is provided with bulb socket through hole 101, top cover through hole 403, light source post through hole 204, lamp socket through hole 205, bulb socket through hole 101 are interconnected and form vent passages so that inside and outside Air circulates and forms the air-flow that can take away rapidly LED bulb internal heat.So, cool exterior air and the heat in vent passages Air is the formation of Air Temperature Difference and atmospheric pressure difference thus forms air-flow, and the air of flowing is taken away rapidly within LED bulb Heat, takes away rapidly heat by spontaneous air flowing, and outside air carries out quick heat exchange, and radiating efficiency is high.So Novel radiator structure, novel structure, and rationally simple, utilize the temperature difference and draught head as power to promote air to flow, shape The air-flow becoming spontaneous takes away rapidly heat, and radiating efficiency is high, good heat dissipation effect, effectively extends the service life of LED light source.Lamp Holder structure is formed in one the integral die-cast part of structure, and holder structure is made up of heat-conducting metal, and conduction heat transfer efficiency is high, heat radiation effect Fruit is preferable.Can be embedded in lamp socket and driving means being surrounded in case driving means it addition, bulb socket 100 extends upward Contacting with holder structure and the enclosure structure 102 of electric shock electric leakage accident occurs, bulb socket 100 is formed in one structure by insulating Material is made, and so may insure that driving means will not touch the metal parts such as holder structure or lamp holder nut, and drives Device can the most exposed and without wrapping up one layer of insulant, good heat dissipation effect.It is new that this utility model achieves a kind of structure Grain husk rationally, is provided with vent passages and forms spontaneous air-flow and take away rapidly heat, and radiating efficiency is high, the LED that security performance is high Bubble.

The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, Every equivalent structure transformation utilizing this utility model description and accompanying drawing content to be made, or directly or indirectly it is used in other phases The technical field closed, is the most in like manner included in scope of patent protection of the present utility model.
