The large bulb lamp of a kind of LED
The utility model relates to a kind of lighting apparatus, and more particularly, it relates to the large bulb lamp of a kind of LED.
At present, the factories and miness lamp (i.e. the large bulb lamp of LED) throwing light on used in factory, power ratio is comparatively large, is all be suspended on workshop, and conventional factories and miness lamp is made up of the lampshade of electrical equipment cover and bottom, the powerful incandescent lamp of general installation in lampshade.Incandescent lamp energy consumption is all higher, and power consumption is larger, not energy-conserving and environment-protective.In the lamp that present illumination is used, most energy-conserving and environment-protective just belong to LED, LED is able to large-scale popularization with advantages such as the high and low power consumption of its brightness, life-span are long.
Existing technology high-power energy saving bulkhead lamp capable adopts two kinds of designs: one is that the wiring board of ballast is directly located in lamp body plastic, become to be integrated with fluorescent tube, become compact type large power electricity-saving lamp, its shortcoming is due to wiring board and fluorescent tube one, fluorescent tube heat upper punch causes the electronic component in wiring board to be in hot environment always, this high ambient temperatures even reaches more than 100 degrees Celsius, therefore causes the lamp life-span short; Two is that fluorescent tube is separated with wiring board, the wiring board of ballast and ballast box Integral design, and ballast is in normal temperature environment substantially, and the service life of this kind of design lamp increases by 2 times to I haven't seen you for ages.
At present, factories and miness lamp on market is all by lamp socket, power supply, pcb board, lampshade, radiator and LED, described LED is arranged on pcb board, radiator is arranged on the side of pcb board LED dorsad, described pcb board is connected with power electric and is all arranged in lamp socket, described lampshade is enclosed within lamp socket and pcb board is isolated from the outside, and LED is towards lampshade direction.This factories and miness lamp uses because of needs in factory, mine lamp environment, need powerful illumination, therefore just need on pcb board, arrange some LED, so just, cause LED to be dispelled the heat because the heat occurred in the course of work all can be delivered on radiator, and radiator and pcb board are close to and are caused the heat dissipation capacity of the heat on its radiator less, and owing to also having the heat of power supply on the opposite side of radiator, thus decrease the radiating surface of radiator, cause radiating effect bad.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the large bulb lamp of the better LED of a kind of radiating effect.
For achieving the above object, the utility model provides following technical scheme: the large bulb lamp of a kind of LED, comprise lamp socket, driving power, pcb board, lampshade, radiator and LED, insulating cylinder is provided with in described lamp socket, described driving power is arranged in insulating cylinder, described radiator is fixedly connected with insulating cylinder, described pcb board is arranged on radiator back to the side of insulating cylinder and is electrically connected with driving power, the inner side of described lamp socket is provided with fin, described radiator is provided with heat transfer sheet, described heat transfer sheet and fin are conflicted, and described lampshade entangles lamp socket.
The utility model is set to further: the inner side of lamp socket is close to by described fin.
The utility model is set to further: described lamp socket comprises cylinder-like body and funnels and is interconnected and forms, and one end of described insulating cylinder is fixedly connected with funnels, and the other end is connected with radiator.
The utility model is set to further: the shape of described radiator is circular piece, the diameter of described radiator coordinates with cylinder-like body, the shape of described heat transfer sheet is cylindric, and one end of described heat transfer sheet is fixedly connected with radiator, and the outside of described heat transfer sheet and fin are conflicted.
Compared with prior art, the utility model has the advantage of: to be connected with radiator by pcb board and to make the heat that pcb board produces because of LED be delivered on radiator, and the heat of driving power heat radiation is also delivered on radiator, by the heat transfer sheet that radiator connects, the heat on radiator is delivered on fin again, due to the cylinder-like body of fin and lamp socket, funnels is close to, heat on fin directly can be delivered on lamp socket and dispel the heat, heat on PCB can be dispelled the heat in time, make the temperature in lamp socket can not be very high, ensure that the service life of the large bulb lamp of LED.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, the large bulb lamp embodiment of LED is described further.
The large bulb lamp of a kind of LED, comprise lamp socket 1, driving power 7, pcb board 2, lampshade 3, radiator 4 and LED 4, insulating cylinder 6 is provided with in described lamp socket 1, described driving power 7 is arranged in insulating cylinder 6, described radiator 4 is fixedly connected with insulating cylinder 6, described pcb board 2 be arranged on radiator 4 dorsad insulating cylinder 6 side and be electrically connected with driving power 7, the inner side of described lamp socket 1 is provided with fin 8, described radiator 4 is provided with heat transfer sheet 9, described heat transfer sheet 9 is conflicted with fin 8, and described lampshade 3 entangles lamp socket 1.
The inner side of lamp socket 1 is close to by described fin 8.
Described lamp socket 1 comprises cylinder-like body 11 and funnels 12 and is interconnected and forms, and one end of described insulating cylinder 6 is fixedly connected with funnels 12, and the other end is connected with radiator 4.
The shape of described radiator 4 is circular piece, and the diameter of described radiator 4 coordinates with cylinder-like body 11, and the shape of described heat transfer sheet 9 is cylindric, and one end of described heat transfer sheet 9 is fixedly connected with radiator 4, and outside and the fin 8 of described heat transfer sheet 9 are conflicted.
Being connected with radiator 4 by pcb board 2 makes the heat that pcb board 2 produces because of LED 4 be delivered on radiator 4, and the heat that driving power 7 dispels the heat also is delivered on radiator 4, by the heat transfer sheet 9 that radiator 4 connects, the heat on radiator 4 is delivered on fin 8 again, due to fin 8 and the cylinder-like body 11 of lamp socket 1, funnels 12 is close to, heat on fin 8 directly can be delivered on lamp socket 1 and dispel the heat, heat on PCB can be dispelled the heat in time, make the temperature in lamp socket 1 can not be very high, ensure that the service life of the large bulb lamp of LED.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
