Abstract
The invention presents a new design of C7 or C9 type LED bulb and its embedded PCB electronic circuit board structure, comprising a lamp cover, LEDs, a PCB circuit board and a base. The bulb houses one or multiple number of LEDs. The LEDs are soldered on the PCB board that is embedded inside of the base. The PCB board power input ports connect to the brass base or are directly wired to outside the base. The base and the lamp cover may be attached together by means of bonding (thermal, sonic or solvent), friction interference fit, adhesive or simply by screwing the lamp cover into the threaded base. The PCB board, utilizing a bridge design, allows the LED bulb to be directly powered by 110-120V AC voltage power sources. The simple bulb design significantly reduces the weight of the entire product and power consumption.
