Abstract:
An LED light bulb includes a lamp housing, an LED filament in the lamp housing and a power module. The LED filament includes a first and a second LED sections, a conductive section, a first and a second conductive electrodes and a light conversion layer. Each LED section includes LED chips connected in serial to from a LED string. The conductive section connects one end of the LED string of the first LED section with one end of the LED string of the second sections. The polarities of the ends of the LED strings are the same. The other ends of the LED strings are respectively connected to the first and the second conductive electrodes. The light conversion layer is coated on at least two sides of the LED chips. The power module's terminals are connected to the conductive section and the conductive electrodes.
