Description
Technical field
The utility model relates to a kind of bulb, particularly relates to a kind of LED bulb with alarm function.
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.But find in Long-Time Service, existing LED bulb, in long-time use, when there is superheating phenomenon, does not usually have the function of warning, thus causes LED bulb to be damaged, also can cause the generation of other security incident time serious.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of LED bulb with alarm function, when superheating phenomenon appears in this LED bulb, can warn user.
For solving the problems of the technologies described above, the utility model provides a kind of LED bulb with alarm function, comprise 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 circular pcb board, evenly spacedly on described pcb board be provided with plurality of LEDs wafer, there is in described radiator a cavity, have in described cavity one be heated after can produce the airbag of expansion, described airbag is connected with a glo-stick, described glo-stick is movable to the outside of described radiator by the passage in described radiator.
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 utility model in use, after LED bulb uses for a long time, when there is superheating phenomenon, airbag just can produce because being heated and expand, under the effect that airbag expands, meeting upwards jack-up glo-stick, makes glo-stick along vertical the moving up of passage, finally passes radiator, when user finds just can know that LED bulb is in overheated state at present after glo-stick passes radiator, thus play the effect of warning.
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, cavity 7, airbag 10, glo-stick 5, passage 3, 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 with alarm function of the present utility model, comprise lamp holder 2, radiator 4 and lampshade 6, wherein lamp holder 2 is connected with the top of radiator 4, lampshade 6 is connected with the bottom of radiator 4, the diapire of radiator 4 is provided with circular pcb board 8, evenly spacedly on this pcb board 8 be provided with plurality of LEDs wafer 9, special feature of the present utility model is: have a cavity 7 in radiator 4, have in this cavity 7 one be heated after can produce the airbag 10 of expansion, this airbag 10 is connected with a glo-stick 5, glo-stick 5 is movable to the outside of radiator 4 by the passage 3 in radiator 4, the setting that concrete passage 3 is vertical in radiator 4, glo-stick 5 part is arranged in passage 3, part is arranged in cavity 7 and contacts with airbag 10, after LED bulb uses for a long time, when there is superheating phenomenon, airbag 10 just can produce because being heated and expand, under the effect that airbag 10 expands, meeting upwards jack-up glo-stick 5, make glo-stick 5 along vertical the moving up of passage 3, finally pass radiator 4, when user finds just can know that LED bulb is in overheated state at present after glo-stick 5 passes radiator, preferred airbag 10 can be anyly have elasticity and the good material of sealing is formed, the gas that its inner filling coefficient of expansion is larger.
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.
