Title:
LED FILAMENT AND LED FILAMENT ILLUMINATION LAMP THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/150230
Kind Code:
A1
Abstract:
Provided is an LED filament (6), comprising a plurality of light-emitting chips (61), a metal electrical connection end head (62), a fluorescent glue (63), an insulating substrate (64) and an electrically conductive magnetically permeable connection piece (65). The plurality of light-emitting chips (61) are connected in series, and encapsulated and fixed on a surface of the insulating substrate (64) via the fluorescent glue (63), one face of the electrically conductive magnetically permeable connection piece (65) is fitted on another surface of the insulating substrate (64), the metal electrical connection end head (62) is electrically connected to a light-emitting chip (61) at one end of the insulating substrate (64), and the electrically conductive magnetically permeable connection piece (65) is electrically connected to a light-emitting chip (61) at another end of the insulating substrate (64). Also provided is an LED filament illumination lamp, comprising a plurality of the LED filaments (6) and a permanent magnet (7). The LED filaments (6) are magnetically and movably connected by means of magnetic attraction via the permanent magnet (7), and are capable of automatic sliding adjustment during thermal expansion and elongation. Light rays of the LED illumination lamp are free from blocking components, the illumination directions are free from shadows, and the LED illumination lamp has a three-dimensional illumination effect.
