LED TUBE LIGHT WITH BENDABLE CIRCUIT BOARD

摘要

An LED tube light having LED light sources, a light tube, end cap, power supply, and an LED light bar is disclosed. LED light bar is a bendable circuit board. One end of the light tube is attached to the end cap; a power supply disposed in end cap and the LED light bar is disposed inside light tube, LED light sources are mounted on LED light bar, the LED light sources and the power supply are electrically connected. LED light bar being bendable circuit board, includes a conductive layer, electrically connected to power supply, and a dielectric layer, the two layers are stackingly arranged, dielectric layer is disposed on the conductive layer away from the LED light sources, and fixed to an inner circumferential surface of the light tube. Bendable circuit board, at two ends thereof, is not fixed to an inner circumferential surface of the light tube.

1. An LED tube light, comprising:
a plurality of LED light sources; an end cap; a light tube, having an end attached to the end cap; a power supply, disposed in the end cap; and an LED light bar, 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 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 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 forms a freely extending end portion at two ends thereof, respectively, wherein the freely extending end portion is an integral portion of the bendable circuit board, upon breaking of the light tube, the broken light tube does not maintain a straight tube configuration so that the LED tube light is structurally rendered unusable.
