  • Publication number: 20100148673
    Abstract: An LED replacement light for a fluorescent lighting fixture. The replacement light assembly includes a metal housing for heat dissipation and structural support. A standard plug for mating with the original lighting fixture connector is provided to allow direct replacement of an existing fluorescent light bulb. A control circuit having a power supply, a current controller, and a current sensor converts the fluorescent lamp power supply output to an output sufficient to drive the LEDs. The current controller generates a variable pulse width waveform for powering the LEDs, and a current sensor circuit regulates the flow of current through the LEDs. High-brightness LEDs are utilized and are spaced sufficiently apart to provide fewer point-sources of light while retaining overall equivalent luminance. A glare shield controls the light pattern emanating from the LEDs to direct the pattern illumination.
