Abstract

A white LED assembly includes a string of series-connected blue LED dice mounted on a substrate. The substrate has a plurality of substrate terminals. A first of the substrate terminals is coupled to be a part of first end node of the string. A second of the substrate terminals is coupled to be a part of an intermediate node of the string. A third of the substrate terminals is coupled to be a part of a second end node of the string. Other substrate terminals may be provided and coupled to be parts of corresponding other intermediate nodes of the string. A single contiguous amount of phosphor covers all the LED dice, but does not cover any of the substrate terminals. In one example, the amount of phosphor contacts the substrate and has a circular periphery. All the LEDs are mounted to the substrate within the circular periphery.
