Abstract
Lighting circuits and strips of linear lighting that can accept either a lower voltage or a higher voltage are disclosed. In the lighting circuit, a repeating block including LED light engines and current-setting elements is divided into two sub-blocks. Terminals are provided that allow the sub-blocks to be connected to voltage and ground in various ways. When the two sub-blocks are connected electrically in parallel with one another, the lighting circuit accepts the lower voltage; when the two sub-blocks are connected electrically in series with one another, the lighting circuit accepts the higher voltage. Circuitry that automatically detects the applied voltage and switches between series and parallel configurations may be included in some embodiments.
