Abstract
A LED-based replacement light for a fluorescent socket is constructed such that a tubular housing has a D-shaped cross section with a flat base with opposing longitudinal edges, opposing sides extending generally perpendicular to the flat base from the opposing longitudinal edges, and a curved surface spanning the opposing sides opposite the flat base. A circuit board structure defines a LED-mounting side with multiple LEDs mounted on the LED-mounting side at predetermined intervals along a length of the circuit board, with at least areas of a primary heat transferring side directly underlying the respective LEDs in thermally conductive relation with the tubular housing for highly electrically insulated thermal transmission of heat generated by the multiple LEDs from the circuit board to an ambient environment surrounding an exterior of the tubular housing. At least one electrical connector is at a longitudinal end of the housing in electrical communication with the circuit board.
