Abstract:
An LED filament and an LED light bulb applying the same are provided. The LED filament includes a conductive section including a conductor; two or more LED sections connected to each other by the conductive section, and each of the LED sections includes two or more LED chips electrically connected to each other through a wire; two electrodes, electrically connected to the LED section; and a light conversion layer with a top layer and a base layer, covering the LED sections, the conductive section and the two electrodes, and a part of each of the two electrodes is exposed respectively. The LED filament is supplied with electric power no more than 8 W, when the LED filament is lit, at least 4 lm of white light is emitted per millimeter of filament length.
