LED bulb with inductive switch
Technical field
The utility model relates to a kind of ligthing paraphernalia, specifically refers to have the LED bulb of inductive switch.
Background technology
Inductive switch control illumination is often adopted in the places such as fire-fighting corridor, toilet, how as shown in Figure 1 the bulb structure that adopts only comprises lamp holder 11 and bulb 12, be at wall or the special inductive switch of the extra installation of ceiling, the complicated cost of circuit is higher, is difficult to installation and repairing.
The utility model content
The utility model has proposed a kind of LED bulb with inductive switch just in order to solve above-mentioned deficiency, and inductive switch directly designs in bulb, special inductive switch need be installed, and the circuit connection construction is simplified during installation, easy access.
Concrete, the utility model has adopted following technical scheme.
Have the LED bulb of inductive switch, comprise lamp holder, lamp holder is provided with bulb, is provided with the LED lamp that is electrically connected with lamp holder in the bulb, and the end of bulb is provided with inductive head, establishes the sensor circuit that is electrically connected with lamp holder and LED lamp in the inductive head.
Said structure directly designs sensor circuit on the LED bulb, do not need at wall or the special inductive switch of the extra installation of ceiling, therefore the utility model can directly access the 220V civil power by lamp holder, directly control light switch by inductive head, and inductive head is located at the end of bulb, the induction range that covers is large, highly sensitive.
In order to prevent that the inductive head on the bulb from blocking generation light dark space when bulb throws, the integral illumination effect of bulb is just bad, therefore the utility model inductive head position can further be improved and be adopted special-purpose PC material as shell, can not affect sensor circuit sensitivity, and do not have the dark space of light, the integral illumination better effects if.
Further, connect radiating seat on the lamp holder, the LED lamp is contained on the radiating seat, and bulb then is located at the radiating seat bottom surface.
Be compared with existing technology, the beneficial effects of the utility model are: sensor circuit directly design does not need the extra special inductive switch of installing in bulb, the inductive head shell adopts special-purpose PC material, does not have the dark space of light.
Description of drawings
Fig. 1 is the structural representation of existing common bulb.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments the utility model is described further.
As shown in Figure 2, it is a kind of embodiment of the present utility model, the LED bulb that has inductive switch shown in the figure, comprise lamp holder 1, lamp holder 1 is provided with bulb 2, be provided with the LED lamp (scheming not shown) that is electrically connected with lamp holder 1 in the bulb 2, the end of bulb 2 is provided with inductive head 3, establishes the sensor circuit (scheming not shown) that is electrically connected with lamp holder 1 and LED lamp in the inductive head 3.
In the illustrated embodiment, connect radiating seat 4 on the lamp holder 1, the LED lamp is contained on the radiating seat 4, and 2 on bulb is located at radiating seat 4 bottom surfaces.
Inductive head 3 can further improve and adopt special-purpose PC material as shell, can not affect sensor circuit sensitivity, and can prevent that the inductive head 3 on the bulb 1 from blocking generation light dark space, integral illumination better effects if when bulb 1 projection.
Said structure directly designs sensor circuit on the LED bulb, do not need at wall or the special inductive switch of the extra installation of ceiling, therefore the utility model can directly access the 220V civil power by lamp holder 1, directly control light switch by inductive head 3, and inductive head 3 is located at the end of bulb 2, the induction range that covers is large, highly sensitive.
For a person skilled in the art, can obtain other various corresponding changes and distortion according to structure and the principle that the utility model discloses, and these all changes and distortion all belong to protection category of the present utility model.
