Claim:
1. An LED tube light, comprising: a plurality of LED light sources; an end cap; a light tube extending in a first direction along a length of the light tube, and having an end attached to the end cap; a power supply comprising a circuit board and one or more circuit elements, disposed in the end cap; and an LED light bar extending in the first direction, and disposed inside the light tube, the LED light sources being mounted on the LED light bar, the LED light sources and the power supply being electrically connected by the LED light bar; wherein the LED light bar is substantially linearly configured and includes a bendable circuit board, the bendable circuit board is made of one conductive layer and one dielectric layer to form a two-layered structure, the dielectric layer is disposed on a surface of the conductive layer that is away from the LED light sources and the dielectric layer is fixed to an inner circumferential surface of the light tube, the LED light sources are disposed on the conductive layer and are electrically connected to the power supply by the conductive layer therebetween, the bendable circuit board has a first end and a second end opposite each other along the first direction, and at least the first end of the bendable circuit board is bent away from the light tube to form a freely extending end portion, wherein the freely extending end portion is an integral portion of the bendable circuit board and extends to be disposed in the end cap and is directly soldered to the power supply.
