Abstract

The utility model discloses a bulb shell structure of an LED bulb. The bulb shell structure comprises a lamp holder, a bulb shell body and a light-transmitting lampshade arranged above the bulb shell body in a covering mode, the bottom of the bulb shell body is directly connected with the lamp holder, the bulb shell body is made of plastics and is hollow, a mounting groove is formed in the hollow position, the outer side of the mounting groove penetrates through the outer wall of the bulb shell body and is exposed out of the external air, a heat dissipation base made of heat dissipation materials is arranged in the mounting groove, the heat dissipation base comprises a through round tube and a plurality of cooling fins arranged around the round tube, after being mounted, and the cooling fins of the heat dissipation base are right inserted in the mounting groove and exposed out of air. The bulb shell body made of plastics and the heat dissipation base made of the heat dissipation materials are adopted, the cooling fins penetrate through the outer wall of the bulb shell body and are exposed out of air, an LED circuit board can be tightly attached to the heat dissipation base, the emitted heat is directly emitted into air through the cooling fins, and the heat dissipation performance is good.

Description

A kind of bubble shell structure of LED bulb

Technical field

The utility model relates to a kind of LED bulb, is specifically related to a kind of cost low and have a LED Lamp bulb case structure of better heat dispersion.

Background technology

Existing LED bulb common configuration complexity, mainly comprises standard lamp head, circuit board and heat dissipation base, and whole radiating seat is by being with aluminium to make and with multi-disc radiating fin, the bottom of radiating seat is connected with lamp holder by insulator.Because whole radiating seat is all made up of aluminium, its difficulty of processing is large, and production cost is high, is not suitable for large-scale promotion.

Also have follow-on as shown in the patent of invention that the patent No. is 201010194595.0, in this patent, adopt plastic cement heat dissipation base and in the neighboring of plastic cement heat dissipation base around being inserted with multi-disc radiating fin, although this structure can reduce the use of heat sink material effectively, weight is lighter, can reduce the manufacturing cost of radiating seat.But this heat dissipation base is installed trouble, and radiating fin easily drops out from heat dissipation base, uses inconvenience.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of bubble shell structure of LED bulb.

The utility model solves the technical scheme that its technical problem adopts:

A kind of bubble shell structure of LED bulb, comprise lamp holder, cell-shell main body and the transparent lamp shade that covers on cell-shell main body top, the bottom of cell-shell main body is directly connected with lamp holder, described cell-shell main body is made of plastics and inner hollow, on hollow position, be provided with mounting groove, the outside of described mounting groove is passed the outer wall of cell-shell main body and is exposed in extraneous air, in described mounting groove, be provided with the radiating seat of being made by heat sink material, logical pipe and the multi-disc fin that arranges around pipe during described radiating seat comprises, after installing, each fin of radiating seat just inserts in mounting groove and is exposed in extraneous air.

In the utility model, the peripheral ring of described cell-shell main body is arranged with multi-disc thin slice, and the position of described thin slice is corresponding with fin with size, and all the fin corresponding with each be at grade for every plate sheet.

In the utility model, the middle part of described radiating seat is provided with two or more screwed holes.

In the utility model, described thin slice and cell-shell main body are one-body molded.

In the utility model, described radiating seat and fin are one-body molded.

The beneficial effects of the utility model are: the utility model is adopted cell-shell main body made of plastic and the radiating seat of being made up of heat sink material, fin passes cell-shell main body outer wall and is exposed in air, LED circuit plate can be close on radiating seat, its heat shedding can directly fall apart in air by fin, perfect heat-dissipating.And more than the radiating seat that the volume ratio of whole radiating seat is traditional is half as large, reduce production cost, be applicable to large-scale promotion.

Brief description of the drawings

Below in conjunction with drawings and embodiments, the utility model is further illustrated:

Fig. 1 is the structural representation of the present embodiment;

Fig. 2 is the structural representation removing after lamp holder and lampshade;

Fig. 3 is the front view of Fig. 2.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, the bubble shell structure of a kind of LED bulb that the present embodiment provides, comprise lamp holder 1, cell-shell main body 2 and the transparent lamp shade 3 that covers on cell-shell main body 2 tops, the bottom of cell-shell main body 2 is directly connected with lamp holder 1, described cell-shell main body 2 is made up and inner hollow of plastic injection-moulded, in cell-shell main body 2, the circuit of circuit board can pass and be connected with lamp holder 1 in vacancy from this, on hollow position, be provided with annular mounting groove 4, the outside of described mounting groove 4 is passed the outer wall of cell-shell main body 2 and is exposed in extraneous air, in described mounting groove 4, be provided with the radiating seat 5 of being made by heat sink material, logical pipe 51 and the multi-disc fin 52 arranging around pipe 51 during described radiating seat 5 comprises, after installing, each fin 52 of radiating seat 5 just inserts in mounting groove 4 and is exposed in extraneous air.Described lamp holder 1 is conventional lamp holder, can be hickey or card interface.

As preferred embodiment, the peripheral ring of described cell-shell main body 2 is arranged with multi-disc thin slice 21, and the position of described thin slice 21 and size are corresponding with fin 52, and all the fin 52 corresponding with each be at grade for every plate sheet 21.The size and shape of described thin slice 21 is the same with the radiating fin of traditional aluminum radiating seat outside, ensures that the specification of whole bulb is consistent.

For convenience of installing, the middle part of described radiating seat 5 is provided with two or more screwed hole 53, and bolt is screwed in this screwed hole through circuit board, and is fixed in cell-shell main body 2.In the present embodiment, described thin slice 21 is plastics and one-body molded with cell-shell main body 2.Described radiating seat 5 and fin 52 are that aluminium alloy is made and are one-body molded.

The foregoing is only preferential embodiment of the present utility model, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
