Abstract
A bending LED bulb has a transparent bending tube and a flexible LED strip. The flexible LED strip has a flexible printed circuit board (PCB) and a plurality of LEDs mounted on the flexible PCB and is inserted and fixed in the transparent bending tube. As the LEDs are sequentially mounted on the flexible PCB, the LEDs are adjacent to a wall of the transparent bending tube, and are equally spaced. Accordingly, a lumen value of the bending LED bulb can be raised, and heat generated by the LEDs can be dissipated out through the wall of the transparent bending tube to avoid high temperature arising from accumulation of the waste heat.
