Abstract:
1. A solid state light engine comprising: a bridge rectifier having a rectified output; at least one light emitting diode (LED) connected to the bridge rectifier, the at least one LED including a die portion, a layer of phosphor free resin positioned upon the die portion, and a plurality of phosphor particles adhered to the layer of phosphor free resin; a pair of AC power input terminals electrically connected to the input of the bridge rectifier for use in coupling the bridge rectifier to an AC power source; and a pair of DC power input terminals connected to the rectified output of the bridge rectifier for use in coupling the bridge rectifier to a circuit productive of a DC voltage at the pair of DC power terminals; wherein the phosphor particles have a persistence in the range between about 40 milliseconds to about 100 milliseconds.
