Description
Technical field
Utility model relates to a kind of bulb, particularly relates to a kind of LED bulb.
Background technology
At present, LED is as a kind of house lighting for alternative tengsten lamp and fluorescent lamp, due to its have that energy consumption is little, light efficiency is large, without mercury, radiationless pollution and the advantages such as material reproducible utilization, in today of energy growing tension, be more and more subject to the welcome of consumer.LED bulb is as the one of LED, lamp holder, radiator and lampshade are generally included, wherein lamp holder is positioned at the top of radiator, lampshade is positioned at the bottom of radiator, and the mode that lampshade is pasted often through glue is fixedly connected with radiator, although, the fasten with glue mode of radiator and lampshade of this profit has and manufactures simple advantage, but, when certain LED light source of lampshade inside needs to change or keep in repair, lampshade can only be removed by the mode destroying lampshade, therefore, make above-mentioned LED bulb there is the more difficult defect of detachable maintaining and problem.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of maintenance, assembles more conveniently LED bulb.
For solving the problems of the technologies described above, the utility model provides a kind of LED bulb, comprise lamp holder, radiator and lampshade, described lamp holder is positioned at the top of described radiator, described lampshade is positioned at the bottom of described radiator, the diapire of described radiator is provided with circular pcb board, evenly spacedly on described pcb board be provided with plurality of LEDs wafer, the connection of described lampshade and described radiator threaded engagement, it is protruding that inwall around described lampshade is provided with a circle, the external diameter of described projection is identical with the diameter of described pcb board, and after described lampshade is connected with described radiator, described pcb board can be pressed on the diapire of described radiator by described projection.
The back side of described pcb board is connected by the diapire of heat conduction glue-line with described radiator.
The surface uniform interval of described radiator be formed with multiple fin.
Described lamp holder is connected with described radiator is dismountable.
The connection of described lamp holder and described radiator threaded engagement.
The outer surface of described lampshade is provided with fluorescence coating.
Compared with prior art, the beneficial effects of the utility model are: due to the connection of lampshade and radiator threaded engagement in the utility model, like this when the pcb board of lampshade inside or LED wafer need to change or maintenance time, only need rotary lampshade just lampshade can be pulled down from radiator, thus need not destroy lampshade, therefore, the utility model maintenance is more convenient, in addition, protruding owing to being provided with a circle around the inwall of lampshade, the external diameter of this projection is identical with the diameter of pcb board, and after lampshade is connected with radiator, firm for pcb board can be pressed on the diapire of radiator by projection just, by protruding effect is compressed to pcb board like this, can effectively prevent pcb board in the movement of longitudinal direction, this mode utilizing protruding fixing pcb board, avoid the mode that traditional profit is screwed pcb board, thus make the utility model have assembling, dismantle convenient advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: lamp holder 2, radiator 4, lampshade 6, pcb board 8, LED wafer 9, protruding 10, heat conduction glue-line 11, fin 12.
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, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 1, a kind of LED bulb of the present utility model, comprise lamp holder 2, radiator 4 and lampshade 6, wherein lamp holder 2 is positioned at the top of radiator 4, lampshade 6 is positioned at the bottom of radiator 4, on the diapire of radiator 4, be provided with circular pcb board 8 simultaneously, evenly spacedly on this pcb board 8 be provided with plurality of LEDs wafer 9, special feature of the present utility model is: the connection of lampshade 6 and radiator 4 threaded engagement, like this when the pcb board 8 of lampshade 6 inside or LED wafer 9 need to change or maintenance time, only need rotary lampshade 6 just lampshade 6 can be pulled down from radiator 4, thus need not destroy lampshade 6, therefore, the utility model maintenance is more convenient, in addition, inwall around lampshade 6 is provided with a circle projection 10, the external diameter of this projection 10 is identical with the diameter of pcb board 8, and after lampshade 6 is connected with radiator 4, protruding 10 just can by the diapire being pressed on radiator 4 firm for pcb board 8, that passes through protruding 10 pairs of pcb boards 8 like this compresses effect, can effectively prevent pcb board 8 in the movement of longitudinal direction, this mode utilizing protruding 10 fixing pcb boards 8, avoid the mode that traditional profit is screwed pcb board 8, thus make the utility model have assembling, dismantle convenient advantage.
In addition, shown in Figure 1, in the utility model, the back side of pcb board 8 is connected by the diapire of heat conduction glue-line 11 with radiator 4, can ensure, between pcb board 8 and radiator 4, there is larger heat exchange area like this, thus guarantee that the utility model has good radiating effect.Simultaneously, multiple fin 12 is formed at the surface uniform interval of radiator 4, the existence of the plurality of fin 12 makes the utility model be provided with larger area of dissipation, can promote radiating effect of the present utility model equally, thus makes the utility model have longer service life.In addition, lamp holder 2 is connected with radiator 4 is dismountable, and preferred lamp holder 2 and the connection of radiator 4 threaded engagement, be conducive to lamp holder 2 like this and state radiator 4 assembling or dismantling, thus person easy to use is to making of the present utility model and maintenance.Finally, the outer surface of lampshade 6 is provided with fluorescence coating (not shown), due to the existence of this fluorescence coating, after lamp extinguishes, fluorescence coating still has remaining light to be existed, thus person easy to use carries out next step action by remaining light, reaches the object of person easy to use.
