1. An LED tube lamp, comprising:
- a glass lamp tube covered by a heat shrink sleeve, wherein the inner surface of the glass lamp tube is formed with a rough surface and the roughness of the inner surface is higher than that of the outer surface, and the glass lamp tube comprises a main body region, a rear end region, and a two-arc-shaped transition region connecting the main body region and the rear end region;
an end cap disposed at one end of the glass lamp tube;
a power supply provided inside the end cap; and
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 a bendable circuit sheet mounted on an inner surface of the glass lamp tube to electrically connect the LED light sources with the power supply, the length of the bendable circuit sheet is larger than the length of the glass lamp tube to form a freely extending end portion at one end of the bendable circuit sheet along a longitudinal direction of the glass lamp tube, the freely extending end portion is electrically connected to the power supply, and the glass lamp tube and the end cap are secured by a hot melt adhesive.

Abstract
An LED tube lamp including a glass lamp tube, an LED light strip disposed inside the glass lamp tube, and an end cap attached over an end of glass lamp tube is disclosed. The glass lamp tube is covered by a heat shrink sleeve. The inner surface of the glass lamp tube is formed with a rough surface or a light scattering region. The glass lamp tube includes a main body region, a rear end region, and a two-arc-shaped transition region connecting the main body region and the rear end region. The LED light strip includes a bendable circuit sheet being longer than the glass lamp tube to form a freely extending end portion.
