LED tube lamp
An LED tube lamp including a glass lamp tube, an end cap disposed at one end of the glass lamp tube, a power supply provided inside the end cap, an LED light strip disposed inside the glass lamp tube with a plurality of LED light sources mounted on. The LED light strip has a bendable circuit sheet to electrically connect the LED light sources with the power supply. The glass lamp tube and the end cap are secured by a highly thermal conductive silicone gel. In addition, the end cap has at least one opening on surface to dissipate heat resulting from the power supply.
1. An LED tube lamp, comprising:
a glass lamp tube;
two end caps, each of the end caps disposed at one end of the glass lamp tube, wherein at least one of the end caps comprises a socket, and at least one opening on surface to dissipate heat;
a power supply provided inside the end cap, wherein the power supply has a metal pin at one end, the end cap has a hollow conductive pin to accommodate the metal pin of the power supply, and the socket is for being inserted with the power supply;
an LED light strip disposed inside the glass lamp tube with a plurality of LED light sources mounted on the LED light strip;
wherein the LED light strip has bendable, substantially planar circuit sheet electrically connecting the LED light sources with the power supply via a bent portion of the circuit sheet, the length of the bendable circuit sheet is larger than the length of the glass lamp tube, and the glass lamp tube and the end cap are secured by a thermal conductive silicone gel.
