Description
Technical field
This utility model relates to a kind of bulb, particularly relates to a kind of good LED bulb of thermal diffusivity.
Background technology
At present, LED is as a kind of house lighting for substituting tengsten lamp and fluorescent lamp, due to its have that energy consumption is little, light efficiency big, without advantages such as hydrargyrum, radiationless pollution and material reproducible utilizations, in today of energy growing tension, be increasingly subject to the welcome of consumer.Many institutes Sundays, existing LED bulb is closed design, and its thermal diffusivity is more weak, thus affects the service life of LED bulb.
Summary of the invention
Technical problem to be solved in the utility model is to provide the LED bulb that a kind of thermal diffusivity is higher.
For solving above-mentioned technical problem, this utility model provides a kind of LED bulb, including lamp holder, radiator and lampshade, described lamp holder is connected with the top of described radiator, described lampshade is connected with the bottom of described radiator, the diapire of described radiator is provided with the pcb board of circle, evenly spaced on described pcb board is provided with many for luminous LED wafer
There is inside described radiator a cavity, described radiator has multiple through hole, described through hole makes described cavity communicate with the outside of described radiator, described radiator is provided with motor, the top of the power transmission shaft of described motor extends in described cavity, and the top of described power transmission shaft is provided with blade.
The back side of described pcb board is connected by the diapire of heat conduction glue-line with described radiator.
The surface of described radiator is evenly spaced is formed with multiple fin.
Described lamp holder is dismountable with described radiator to be connected.
The connection that described lamp holder coordinates with the male thread on described radiator.
Outer surface at described lampshade is provided with fluorescence coating.
Compared with prior art, the beneficial effects of the utility model are: due at this utility model, when assembling more heat transfer in cavity, motor driven vane works, it is possible to quickly via through holes heat radiation, thus make this utility model have good thermal diffusivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and embodiments, this utility model is described in further details.At this, exemplary embodiment of the present utility model and explanation are used for explaining this utility model, but are not intended as restriction of the present utility model.
Shown in Figure 1, a kind of LED bulb of the present utility model, including lamp holder 2, radiator 4 and lampshade 6, lamp holder 2 is connected with the top of radiator 4, lampshade 6 is connected with the bottom of described radiator 4, the diapire of radiator 4 is provided with the pcb board of circle, evenly spaced on pcb board is provided with many for luminous LED wafer 8
Radiator 4 is internal has a cavity 10, radiator 4 has multiple through hole 12, through hole 12 makes cavity 10 communicate with the outside of radiator 4, being provided with motor 14 in radiator 4, the top of the power transmission shaft 16 of motor 14 extends in cavity 10, and the top of power transmission shaft 16 is provided with blade 18, when cavity 10 is assembled more heat transfer, motor 14 driven vane 18 works, it is possible to quickly via through holes heat radiation, thus makes this utility model have good thermal diffusivity.
Additionally, shown in Figure 1, in this utility model, the back side of pcb board is connected by the diapire of heat conduction glue-line with radiator 4, so can ensure that there is between pcb board and radiator 4 bigger heat exchange area, so that it is guaranteed that this utility model has good radiating effect.Simultaneously, evenly spaced on the surface of radiator 4 it is formed with multiple fin, the existence of the plurality of fin makes this utility model be provided with bigger area of dissipation, and equally possible lifting radiating effect of the present utility model, so that this utility model has longer service life.Being connected additionally, lamp holder 2 is dismountable with radiator 4, it is preferable that the connection of lamp holder 2 and radiator 4 threaded engagement, being so conducive to lamp holder 2 and 4 assembly and disassembly of stating radiator, thus facilitating user to making of the present utility model and maintenance.Finally, the outer surface at lampshade 6 is provided with fluorescence coating (not shown), and due to the existence of this fluorescence coating, after lamp extinguishes, fluorescence coating still has remaining light to be existed, thus facilitating user to carry out next step action by remaining light, reaches to facilitate the purpose of user.
