Abstract:
An LED filament and an LED light bulb applying the same are disclosed. The LED filament includes LED chips, conductive electrodes disposed corresponding to the LED chips, and a light conversion coating. The LED chips are electrically connected together and the conductive electrodes are electrically connected with the LED chips. The light conversion coating includes an adhesive and a plurality of phosphors. The light conversion coating coats on at least two sides of the LED chips and the conductive electrodes. The light conversion coating exposes a portion of two of the conductive electrodes. Accordingly, the LED filament is capable of emitting light similar to that a point light source does and the LED light bulb may emit omnidirectional light.
