The power supply assembly is sleeved in the inner cavity of the radiator, the outer wall of the power supply assembly tightly adheres to the inner cavity wall of the radiator, and a light source is fixedly arranged at the upper portion of the radiator. The power supply assembly comprises a power supply box and a driving power supply, wherein the driving power supply is sleeved in the power supply box. The radiator comprises a heat tube and fins, wherein the fins are inserted on the periphery of the heat tube, and the surfaces of the fins and the heat tube are provided with insulating layers. The power supply assembly, the radiator and the light source are fixedly sleeved in a light-transmitting cover, and the bottom of the light-transmitting cover is provided with the opened end. The radiator is arranged inside the LED bulb lamp adopting the structure and can outward radiate heat emitted by the driving power supply and the light source as soon as possible, accordingly the temperature of the bulb lamp is reduced, and the service life is prolonged. The LED bulb lamp is good in using performance, the power supply assembly tightly adheres to the inside of the radiator, a heat radiating separation distance is large, the heat radiating effect is improved, and the insulating layers wrapped on the surfaces of the heat tube and the fins ensure the using safety.

Description

The LED bulb lamp

Technical field

The utility model relates to field of illumination lamp technology, specifically refers to a kind of LED bulb lamp.

Background technology

Due to the energy-saving and environmental protection of LED light fixture, at present, the LED lighting is used more and more, the inner chamber of the radiator of existing LED bulb lamp is circular, and power supply module is square, if power supply module is placed in radiator, both laminating degree are poor, can cause the spacing of power supply module discrete heat device excessive, cause the heat of power supply to be difficult for conduction release, the life-span of LED bulb lamp is shorter.In addition, the structure of some radiator is too complicated, has increased the manufacturing cost of LED bulb lamp.

The utility model content

The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, provides that a kind of power supply module and radiator fit tightly, the LED bulb lamp of bulb lamp good heat dissipation effect, low cost of manufacture, long service life.

For realizing above-mentioned purpose, LED bulb lamp of the present utility model has following formation:

This LED bulb lamp, its main feature is, comprises power supply module and radiator, and this power supply module is sheathed in described lumen of radiator, and the outer wall of described power supply module is close to the internal chamber wall of described radiator, the top of described radiator is fixedly installed light source.

Power supply module in this LED bulb lamp comprises power pack and driving power, and this driving power is sheathed in described power pack.

Power pack in this LED bulb lamp is square.

The inner chamber of the radiator in this LED bulb lamp is square, and this inner chamber is corresponding with described power pack.

Radiator in this LED bulb lamp comprises heat pipe and have a liking for sheet, and this has a liking for the periphery that sheet is inserted in described heat pipe, and described surface of having a liking for sheet and described heat pipe has insulating barrier.

Heat pipe in this LED bulb lamp, describedly have a liking for sheet and described insulating barrier is integrated setting.

Power supply module in this LED bulb lamp, described radiator and the equal fixed cover of described light source are located in diffuser, and described radiator is arranged at the bottom of this diffuser, and the bottom of described diffuser has openend.

Lamp holder in this LED bulb lamp is arranged at the below of described radiator, and the openend of this lamp holder and described diffuser is fixedly connected with, and this lamp holder is connected with described power supply module.

Adopted the LED bulb lamp of this structure, simple in structure, the similar common bulb of profile, its inside is except light source, also be provided with radiator, the heat that radiator can give out driving power and light source outwards distributes as early as possible, thereby reduces the temperature of bulb lamp, make its life-span than common bulb longer, serviceability is better.Power supply module closely is sheathed on the inside of radiator, makes and has less heat radiation spacing, excellent in heat dissipation effect.Heat pipe in radiator all is coated with insulating barrier with the surface of having a liking for sheet, thereby guarantees to use safety.

The accompanying drawing explanation

The explosive view that Fig. 1 is LED bulb lamp of the present utility model.

Fig. 2 is LED ball bulb lamp structure schematic diagram of the present utility model.

Number in the figure is described as follows:

1 lamp holder

2 power packs

3 driving powers

4 radiators

5 light sources

6 diffusers

The specific embodiment

In order more clearly to understand technology contents of the present utility model, especially exemplified by following examples, describe in detail.

Refer to Fig. 1 and Fig. 2, this LED bulb lamp, comprise power supply module and radiator 4, this power supply module is sheathed in radiator 4, power supply module comprises power pack 2 and driving power 3, this driving power 3 is sheathed on power pack interior 2, the internal chamber wall of the outer wall held against heat sink 4 of power pack 2, thereby play best radiating effect, the heat that power supply module is produced full out reaches radiator 4, power pack 2 is square, and the inner chamber of radiator 4 is also square, and the shape of this inner chamber is corresponding with the profile of power pack 2.The top of radiator 4 is fixedly installed light source 5, this light source 5 gives out light, this LED bulb lamp in use, driving power 3 in power supply module can give out heat, therefore be placed in radiator 4, also can give out heat after the long-time use of light source 5, radiator 4 also can play certain thermolysis to light source 5.

Radiator 4 comprises heat pipe and has a liking for sheet, having a liking for sheet is sheet, have a liking for the periphery that sheet is inserted in heat pipe, having a liking for sheet concrete sheet number and size determines according to actual needs, the surface of having a liking for sheet and heat pipe has insulating barrier, due to the LED bulb lamp in use, power supply module can send a large amount of heats, have a liking for sheet and heat pipe and also can correspondingly reach higher temperature, exposedly have a liking for sector-meeting and cause danger, the surface of therefore having a liking for sheet and heat pipe has insulating barrier, thereby guarantees the security of using, heat pipe, have a liking for sheet and insulating barrier can be integrated setting, thereby simplify the overall structure of radiator 4.

Power supply module, radiator 4 and the equal fixed cover of light source 5 are located in diffuser 6, light evenly distributes to diffuser 6 is outer, radiator 4 is arranged at the bottom position in this diffuser 6, the bottom of diffuser 6 has openend, lamp holder 1 is fixedly connected with the openend of diffuser 6, and lamp holder 1 and diffuser 6 have sealed other inner assembly, and lamp holder 1 is connected with power supply module.

In this specification, the utility model is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
