摘要： A system and method of converting a light fixture from a conventional light fixture to an LED light fixture. Originally, the light fixture has a troffer, a ballast unit, and bulb receptacles. The conversion is accomplished by mounting a panel over the face of the troffer that obscures the ballast unit and bulb receptacles. LED light strips are mounted to the panel. Likewise, an LED power supply is mounted to the panel. The panel is attached to the troffer with a hinge connection. In this manner, the panel can be rotated away from the troffer for easy access.

摘要： The light fixture includes a frame configured to define a channel, and a substantially flat light emitting diode (LED) panel disposed within the frame. Power circuitry is disposed within the first channel, the power circuitry being configured to electrically couple the substantially flat LED panel to an external AC power supply. The power circuitry is sized to be positioned within the first channel and has a length and a width, the length-to-width ratio being at least 5 to 1, and optionally at least 10 to 1. The power circuitry is configured to convert an AC input into a DC output suitable for powering the substantially flat light emitting diode (LED) panel. The substantially flat light emitting diode (LED) panel includes an optically transmissive panel, and an array of LEDs disposed adjacent to an edge of the optically transmissive panel and disposed adjacent at least one edge of the frame.
