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.

Disclosed herein is an illumination device including light-emitting diodes, an alternating current input, a full-wave rectifier coupled to the alternating current input and configured to produce a rectified voltage output and a power converter, the power converter having a switching element electrically coupled to the rectified voltage output of the full-wave rectifier. An improvement of the illumination device includes a feedback circuit configured to determine an average current across the light-emitting diodes and to invert a signal representing the average current to provide a switching signal to the switching element such that, for a range of operating points, increasing a current drawn into the power converter will decrease LED power and decreasing the current drawn into the power converter will increase LED power.

Disclosed herein are embodiments of replacement lights for conventional fluorescent tube lights for use in a conventional fluorescent fixture. One embodiment comprises a tubular housing, a circuit board disposed within the housing, a pair of end caps disposed on opposing ends of the tubular housing with at least one pin connector extending from each end cap, an array of LEDs arranged longitudinally along the circuit board, a number and spacing of the LEDs being such as to uniformly and fully occupy a space between the end caps, wherein at least one of the connectors is electrically connected to the LEDs and a wavelength-converting material in contact with at least a portion of the tubular housing. The wavelength-converting material is excited by transmitted light from the LEDs to produce visible light.

An LED-based light can be installed in a conventional light fixture. The LED-based light can include a sensor operable to output a first signal indicative of whether an area of one or more of the rooms is in an occupied state or a non-occupied state, and the LED-based light can also include an LED controller operable to control at least one LED in the light in response to the first signal. Additionally, the LED-based light can include a transmitter operable to output a second signal indicative of whether the area is in the occupied state or the non-occupied state to a building environment regulator.

A fluorescent light tube retrofit with light emitting diodes (LEDs) that evenly distribute light to avoid bright spots is disclosed. One tube in the form of a conventional fluorescent tube includes two LEDs mounted to the tube on opposite sides of a single circumference of the tube. The LEDs can face the center of the tube, or the LEDs can be offset facing relative to the center of the tube. A reflecting surface can be disposed inside the tube to reflect light evenly toward an arc of the tube. Alternatively, at least one LED can be oriented to direct light into a light pipe that curves around the interior of the tube.
