Description
Technical field
The utility model relates to a kind of bulb, particularly relates to the good LED bulb of a kind of sealing.
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, because the lampshade of bulb is generally plastic material, it easily produces deformation after being heated, to such an extent as to the junction of lampshade and radiator can produce trickle gap, such dust will be entered in lampshade by above-mentioned trickle space, to such an extent as to can affect the illuminating effect of LED bulb.
Summary of the invention
Technical problem to be solved in the utility model is to provide the good LED bulb of a kind of sealing, and this LED bulb can prevent dust from entering in lampshade.
For solving the problems of the technologies described above, the utility model provides a kind of sealing good LED bulb, 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, the connection of described lampshade and radiator threaded engagement, the end face of the opening part of described lampshade is provided with a circle metal level, be provided with the magnet circle that a circle is corresponding with described metal level on a heat sink.
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: because the utility model is provided with a circle metal level on the end face of the opening part of lampshade, be provided with the magnet circle that a circle is corresponding with metal level on a heat sink, even if lampshade is heated generation deformation like this, but metal level and magnet circle still can adsorb formation entirety, thus do not have and make that lampshade is inner to be produced with the outside space communicated of lampshade, to such an extent as to dust can be organized to enter in lampshade, therefore, sealing of the present utility model is better.
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, metal level 7, magnet circle 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, the good LED bulb of a kind of sealing 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, 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, on the end face of the opening part of lampshade 6, be provided with a circle metal level 7 simultaneously, radiator 4 is provided with the magnet circle 10 that a circle is corresponding with metal level 7, by this structural design, the generation deformation even if lampshade 6 is heated, but metal level 7 and magnet circle 10 still can adsorb formation entirety, thus do not have the space that communicates with lampshade 6 outside, lampshade 6 inside is produced, thus dust can be organized to enter in lampshade, therefore sealing of the present utility model is better.
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.
