| Title: |
Flexible LED Lighting Strip |
| Abstract: |
A flexible lighting device, comprising an elongated flexible tube including
a translucent tubular shell with opposed tube ends, a flexible helical
circuit board positioned in said tube extending between said opposed tube
ends, said flexible helical circuit board having an exterior surface
spaced from said tubular shell. Electrical circuitry is mounted to the
circuit board and is connected to an external input source and an output
source of electrical power. A plurality of light emitting diodes (LEDs) is
mounted to the exterior surface of the helical circuit board and is
electrically connected to the electrical circuitry. The LEDs are
positioned adjacent to the tubular wall. The invention includes a method
of making the flexible lighting device including providing a
parallelogram-shaped flat circuit board having long edges and short edges
with acute angles and obtuse angles and further including a stiffening
member embedded with said flat circuit board. Electrical circuitry mounted
to the flat circuit board and LEDs mounted to the flat circuit board and
to the electrical circuitry thereon, are all rolled and extended into a
flexible cylindrical circuit board having spaced spirals and gaps that
hold the LEDs, and then inserted into the flexible tubular housing. Power
input and power output connectors are added to the electrical circuitry of
the flexible helical circuit board, and connector end caps are secured to
the opposed ends of the tubular housing.
