LED tube lamp
First Claim
1. An LED tube lamp, comprising:
- a lamp tube, having an LED light bar disposed inside the lamp tube with a plurality of LED light sources on the LED light bar;
two end caps respectively at two opposite ends of the lamp tube; and
a power supply in one or separately in both of the end caps,wherein each of the end caps comprises;
an electrically insulating tube;
a magnetic metal member, disposed on an inner circumferential surface of the electrically insulating tube;
a hot melt adhesive disposed on an inner circumferential surface of the magnetic metal member; and
two conductive pins disposed on the electrically insulating tube,wherein the hot melt adhesive comprises phenolic resin 2127, shellac, rosin, calcium carbonate powder, and zinc oxide.

Abstract
An LED tube lamp having LED light sources, a lamp tube, end cap, power supply, a reflective film layer and an LED light bar is disclosed. The LED light bar is a bendable circuit sheet. One end of the lamp tube is attached to the end cap; a power supply disposed in end cap and the LED light bar is disposed inside lamp tube. The end cap includes an electrically insulating tubular part, sleeved with the end of the lamp tube and a magnetic metal object disposed between an inner circumferential surface of the electrically insulating tubular part and the end of lamp tube. The reflective film layer is disposed on inner circumferential surface of lamp tube, and occupying a portion of inner circumferential surface of lamp tube along circumferential direction thereof. LED light sources are disposed above or adjacently to one side of reflective film layer.
