LED tube lamp
DC CAFCFirst Claim
1. An LED tube lamp, comprising:
- a tube, comprising;
a main body; and
two rear end regions respectively at two ends of the main body, wherein an outer diameter of each of the rear end regions is less than that of the main body;
two end caps respectively sleeving the two rear end regions, each of the end caps comprising;
a metal ring member substantially coaxial with the tube, the metal ring member sleeving the respective rear end region;
an insulating end wall substantially perpendicular to the axial direction of the tube; and
two pins on the insulating end wall for receiving an external driving signal;
an LED light strip disposed on an inner circumferential surface of the main body with a plurality of LED light sources mounted thereon;
a power supply disposed at one end or two ends of the tube and configured to drive the plurality of LED light sources; and
an adhesive disposed between each of the metal ring members and each of the rear end regions;
wherein a rough layer is formed on the inner circumferential surface of the main body and the roughness of the rough layer is higher than that of the outer surface of the main body, so that the light emitted from the LED light sources passing through the rough layer and then through the main body.

Abstract
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. At least a part of an inner surface of the glass lamp tube is formed with a rough surface, and the glass lamp tube is covered by a heat shrink sleeve. The LED light strip has a bendable circuit sheet which is made of a metal layer structure 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 with its thermal conductivity not less than 0.7 w/m·k.
