Tubular LED Lamp
First Claim
1. An LED lamp comprising a thermoformed circuit board and a tubular body having a diffuser and;
- the thermoformed circuit board comprising a substrate, an intermediate circuit board having electrical conductors, and a coverlay laminated to the substrate, the intermediate circuit board and electrical conductors being disposed between the substrate and the coverlay, the coverlay having openings in which light-emitting diodes (LEDs) are mounted and electrically connected to the electrical conductors of the intermediate circuit board;
each of the substrate and coverlay being comprised of a formable polymer material; and
the thermoformed circuit board having an elongated shape with an arcuate cross section.

Abstract
There is herein described an LED lamp comprising a thermoformed circuit board and a tubular lamp body having a diffuser. The thermoformed circuit board comprises a substrate, an intermediate circuit board having electrical conductors, and a coverlay laminated to the substrate. The intermediate circuit board and electrical conductors are disposed between the substrate and the coverlay which has openings in which light-emitting diodes (LEDs) are mounted and electrically connected to the electrical conductors of the intermediate circuit board. Each of the substrate and coverlay is comprised of a formable polymer material and the thermoformed circuit board has an elongated shape with an arcuate cross section. Since the thermoformed circuit board has a curvature that can be substantially the same as the curvature of the tubular lamp body, the LED may be located approximately at the circumference of the lamp.
