Document Type and Number:

WIPO Patent Application WO/2017/028787

Kind Code:

A1

Abstract:

An LED filament (100) and an LED light bulb (10a, 10b, 10c) applying the same are disclosed. The LED filament (100) includes LED chips (102, 104), conductive electrodes (110, 112) disposed corresponding to the LED chips (102, 104), and a light conversion coating (120). The LED chips (102, 104) are electrically connected together and the conductive electrodes (110, 112) are electrically connected with the LED chips (102, 104). The light conversion coating (120) includes an adhesive (122) and a plurality of phosphors (124). The light conversion coating (120) coats on at least two sides of the LED chips (102, 104) and the conductive electrodes (110, 112). The light conversion coating (120) exposes a portion of two of the conductive electrodes (110, 112). Accordingly, the LED filament (100) is capable of emitting light similar to that a point light source does and the LED light bulb (10a, 10b, 10c) may emit omnidirectional light.
