Refering to Fig. 1 and Fig. 2, the embodiment of the present invention provides a kind of LED bulb, including lamp body 1, LED 2, dc source 3,
PCB control panels 7, the interface 4 and diffuser 5 being connected with the external world, interface 4 are located at the bottom of lamp body 1, and diffuser 5 is located at lamp body 1
Top, LED 2, dc source 3 and PCB control panels 7 are inside the lamp body 1, in addition to aluminium base 6, and aluminium base 6 is located at
The top open part of lamp body 1, diffuser 5 is located at the top of aluminium base 6, and LED 2 is evenly distributed on the upper side of aluminium base 6,
LED 2 is some pieces of paster LEDs, reduces the heat of LED 2 itself generation, and can to provide scope larger for paster LED
Lighting angle.
In an embodiment of the present invention, LED 2 as the aluminium base 6 of carrier with lamp body 1 by separating, convenient use person
Maintenance and replacing, it is to avoid the situation for abandoning whole LED bulb of having to when LED bulb does not work, effectively reduce
The use cost of LED bulb.
Specifically, PCB control panels 7 are located at the lower section of aluminium base 6, and dc source 3 is located at the lower section of PCB control panels 7, direct current
The output end of power supply 3 is fixedly connected with lamp body 1, and interface 4 is located at the lower section of dc source 3.
Referring again to Fig. 3, PCB control panels 7 include power circuit block 71, controlling switch module 72 with receiving extraneous simulation
The control circuit module 73 of signal, power circuit block 71 is connected with controlling switch module 72, control circuit module 73 and control
Switch module 72 is connected, and controlling switch module 72 is connected with LED 2, dc source 3 respectively with power circuit block 71 and control
Switch module 72 is connected.
Embodiments of the invention have been converted the built-in power technology of LED lamp tube, and direct current is additionally arranged in common LED bulb
Power supply 3, and the control by PCB control panels 7 to the driving power supply of LED 2 so that LED bulb has following functions：
One is that in the case of with external power supply, on the one hand driving LED 2 is illuminated, on the other hand to direct current
Charged in source 3；
Two be when the electric current of external power supply offer e insufficient to driving LED 2, by dc source 3 together as driving
The driving power supply that LED 2 is illuminated；
Three be that in the case of no external power supply, LED 2 is used as driving current using the direct current in dc source 3.
Now, LED 2 by PCB control panels 7 with dc source 3 without being connected, as long as being linked to be logical between LED 2 and dc source 3
Road, LED bulb can be carried out illumination.
Further, lamp body 1 is in hollow coniform, and lamp body 1 is included located at the conductive layer 11 of inner side and located at outside
