Abstract
A flexible lighting device includes an elongated flexible tube with a translucent tube shell and opposed tube ends and a flexible circuit board set in the tube so that it extends between the tube ends. The flexible circuit board has opposed interior and exterior surfaces. Electrical circuitry is mounted to the circuit board and connected to an external input source and an output source of electrical power. The circuit board defines a number of cut-outs, preferably those of a generally diamond shape. The device is described in two embodiments: one with inwardly directed LEDs on the circuit board directed into the tube and one with outwardly directed LEDs on the circuit board directed out of the tube. The method of making the flexible lighting device is also described.
