Abstract
The utility model discloses an LED bulb. The LED bulb comprises a lamp cap, an LED power source, an LED light source and a lampshade. The LED light source is installed in the lamp cap in an interference fit mode, the LED power source is installed in the lamp cap and respectively and electrically connected with the LED light source and the lamp cap, and the lampshade is fixedly connected to the lamp cap. The LED bulb has the advantages of being simple and safe in structure, good in heat-dissipating effect, large in light-emitting area and the like.
Description
Technical field
The utility model relates to a kind of lighting, particularly relates to a kind of LED bulb.
Background technology
Existing LED bulb is normally comprised of lamp holder, lamp socket, radiator, LED light source, LED power supply and lampshade, wherein, LED light source is arranged on the top of metal heat sink, the periphery of metal heat sink is enclosed with plastic lamp holder to play insulating effect, metal heat sink and lampshade are arranged on plastic lamp holder, and plastic lamp holder is arranged on lamp holder.Yet, due to the setting of radiator and lamp socket, causing LED bulb to have complex structure, defect that structural volume is large, and be subject to the restriction of holder structure, lampshade is generally hemispherical dome structure, and its light-emitting area is little, causes the lighting effect of LED bulb undesirable.
Utility model content
Based on this, be necessary for the existing problem of existing LED bulb, a kind of simple in structure, LED bulb that light-emitting area is large is provided.
A kind of LED bulb, comprise lamp holder, LED power supply, LED light source and lampshade, wherein, described LED light source interference fit is arranged in described lamp holder, described LED power supply is arranged in described lamp holder and is electrically connected to described LED light source and lamp holder respectively, and described lampshade is fixedly connected on described lamp holder.
Therein in an embodiment, described LED light source comprises aluminium base and is arranged on the LED lamp pearl on described aluminium base, and described aluminium base is electrically connected to described LED lamp pearl and LED power supply respectively.
In an embodiment, described aluminium base interference fit is arranged in described lamp holder therein.
In an embodiment, described aluminium base and the junction of described lamp holder are filled with heat conductive silica gel therein.
Therein in an embodiment, the spherical in shape or candle of described lampshade.
In an embodiment, described lampshade is glass lamp shade or heat-conducting plastic lampshade therein.
In LED bulb described in the utility model, because the aluminium base in LED light source has good heat conduction, thermolysis, by LED lamp pearl is arranged on aluminium base, and aluminium base interference fit is arranged in lamp holder, the heat producing while making the work of LED lamp pearl can be transmitted on lamp holder by aluminium base, because lamp holder is directly connected with lampshade, and lamp holder, lampshade all contacts with air, therefore, the heat producing during the work of LED lamp pearl can be by lamp holder and lampshade, mode with convection current and radiation is transmitted in air, reach thus good heat radiation, cooling-down effect, can extend the service life of LED lamp pearl.In the utility model, owing to dispelling the heat without structures such as using radiator and lamp socket, thereby simplified the structure of LED bulb, reduced the manufacturing cost of LED bulb; In addition, owing to lampshade directly can being fixedly connected on lamp holder, can increase the surface area of lampshade, expand the lighting angle (can reach 320 °) of LED bulb, improve the lighting effect of LED bulb; Moreover LED power supply, LED light source are all directly installed in lamp holder, lamp holder is also directly fixedly connected with lampshade, has avoided the metal parts such as radiator to expose the potential safety hazard causing.
Accompanying drawing explanation
Fig. 1 is the perspective view of LED bulb described in the utility model;
Fig. 2 is the cross-sectional view of LED bulb described in the utility model;
Fig. 3 is the decomposition texture schematic diagram of LED bulb described in the utility model.
The specific embodiment
As shown in Figure 1 to Figure 3, LED bulb described in the utility model comprises lamp holder 1, LED power supply 2, LED light source 3 and lampshade 4.
Lampshade 4 is glass lamp shade or heat-conducting plastic lampshade, and its shape can be spherical or candle etc.
Because aluminium base 31 is metallic aluminium material, it has good heat conduction, thermolysis, LED lamp pearl 32 is arranged on aluminium base 31, and aluminium base 31 interference fit are arranged in lamp holder 1, thereby the heat producing while making 32 work of LED lamp pearl is transmitted on lamp holder 1 by aluminium base 31, because lamp holder 1 is directly connected with lampshade 4, and lamp holder 1, lampshade 4 all contacts with air, therefore, the heat producing during 32 work of LED lamp pearl can pass through lamp holder 1 and lampshade 4, mode with convection current and radiation is transmitted in air, reach thus good heat radiation, cooling-down effect, extend the service life of LED lamp pearl 32.
In addition, because LED power supply 2 and LED light source 3 are all directly installed in lamp holder 1, lamp holder 1 is also directly fixedly connected with lampshade 4, simplified thus the structure of LED bulb, dwindled the overall volume of LED bulb, and the surface area of lampshade 4 is increased, improved the lighting effect of LED bulb, also avoided metal parts to expose the potential safety hazard causing.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
