    摘要: A uniform luminance light-emitting diode (LED) circuit board includes a first primary trace and a second primary trace mounted on a substrate along a direction and are spaced apart, multiple LED strings mounted on the substrate along the direction and parallelly connected between the first primary trace and the second primary trace, a first power trace and a second power trace respectively connected to the first primary trace and the second primary trace, and a first auxiliary trace with two ends respectively connected to the second primary trace and the second power trace. By adjusting trace widths of the first primary trace and the second primary trace to limit current passing through each LED string and using the first auxiliary trace to provide an additional current path, identical current flowing through all the LED strings results in uniform luminance of the LED strings.

    摘要: A light assembly contains a troffer containing a housing. One or more LED light units are contained within the troffer, wherein each of the LED light units contain only one corresponding conductive end cap. A pair of conductors extending from each of the corresponding conductive end caps are mated with a corresponding socket contained within a DC power supply module contained within the troffer.
