Abstract
A tube that is at least partially optically transmissive. An LED mounted on a substrate is positioned in the tube and is operable to emit light through the tube when energized through an electrical path. Pins are in the electrical path. An electrical conductor electrically couples the pins to the electrical path, the electrical conductor is biased into engagement with an electrical contact on the substrate. The substrate may be secured to the tube by an adhesive. The substrate may be secured to the end caps and be suspended in the tube.
