Abstract
The invention discloses an LED bulb with a defogging function. The LED bulb comprises a lamp cap (2), a radiator (4) and a lampshade (6). The lamp cap (2) is connected with the top of the radiator (4). The lampshade (6) is connected with the bottom of the radiator (4). A round PCB (8) is arranged on the bottom wall of the radiator (4). A plurality of LED wafers (9) are disposed on the PCB (8) at equal intervals. The LED bulb is characterized in that a cavity (7) is formed in the radiator (4); a bag (10) containing a drying agent and provided with pores is disposed in the cavity (7); the cavity (7) is communicated with the interior of the lampshade (6) through a plurality of channels (5) in the radiator (4). By means of the LED bulb, the environment in the lampshade can always be dry.
Description
Technical field
The present invention relates to a kind of bulb, particularly relate to a kind of LED bulb with defrosting 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, 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, applying the LED bulb of wet environment without like this, entering in lampshade with regard to having fog by above-mentioned trickle space, first the illuminating effect of LED bulb can be affected, secondly the situation of short circuit also can be caused to occur, therefore, prevent fog from entering lampshade inside most important.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of LED bulb, and this LED bulb can eliminate the fog of lampshade inside fast.
For solving the problems of the technologies described above, the invention provides a kind of LED bulb with defrosting 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, be provided with one in this cavity and drier be housed and surface has the bag of pore, described cavity is communicated with the inside of described lampshade by the multiple passage be arranged 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.
Described lamp holder and the described connection stating radiator threaded engagement.
The outer surface of described lampshade is provided with fluorescence coating.
Compared with prior art, beneficial effect of the present invention is: due to the present invention in use, after fog enters lampshade by the gap between lampshade and radiator, can be absorbed by the drier in bag along passage, thus ensure to use in lampshade that there is dry environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: lamp holder 2, radiator 4, lampshade 6, pcb board 8, LED wafer 9, cavity 7, passage 5, bag 10, heat conduction glue-line 11, fin 12.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with drawings and embodiments, the present invention is described in further details.At this, exemplary embodiment of the present invention and illustrating for explaining the present invention, but not as a limitation of the invention.
Shown in Figure 1, a kind of LED bulb with defrosting function of the present invention, 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 invention is: in radiator 4, have a cavity 7 near pcb board 8 place, be placed with one in this cavity 7 and drier be housed and surface has the bag 10 of pore, cavity 7 is communicated with the inside of lampshade 6 by the multiple passages 5 be arranged in radiator 4 simultaneously.By this structural design, after fog enters lampshade 6 inside by the gap between lampshade 6 and radiator 4, can be absorbed by the drier in bag 10 along passage 5, thus ensure to use in lampshade 6 that there is dry environment.
In addition, shown in Figure 1, in the present invention, 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 present invention has good radiating effect.Meanwhile, be formed with multiple fin 12 at the surface uniform interval of radiator 4, the existence of the plurality of fin 12 makes the present invention be provided with larger area of dissipation, can promote radiating effect of the present invention equally, thus makes the present invention 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 invention 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.
