Title: FLEXIBLE LED LAMP FILAMENT AND LED LAMP
Abstract:
A flexible light-emitting diode (LED) lamp filament (100) and an LED lamp (200), the flexible LED lamp filament (100) comprising a flexible substrate (110), a plurality of LED chips (123), an insulating layer (121), fluorescent glue (124) and a circuit layer (122). The flexible substrate (110) comprises a second part (120) and a first part (130). The distance between every two adjacent LED chips (123) among the plurality of LED chips (123) is gradually reduced in the direction from the center of the second part (120) to the two ends thereof, and thus heat in the middle of the second part (120) during usage of the flexible LED lamp filament (100) is reduced. In addition, the heat of the second part (120) of the flexible LED lamp filament (100) may be further dissipated by means of the first part (130) of the flexible substrate (110), thereby improving the heat dissipation capability and effective load capability of the flexible LED lamp filament (100), and achieving the effects of energy conservation and being environmentally friendly.
