Abstract
Apparatus and associated methods relate to a dual-input voltage range compatible light adapted to reconfigure two light elements in series or in parallel and make corresponding current limit adaptations, in response to the input voltage entering one of two predetermined ranges. In an illustrative example, the lighting elements may be strings of LEDs. The current limit may be regulated, for example, by two linear current regulators. In various examples, the current through each of the light elements may be maintained at a predetermined current level independent of the input voltage range. A network of switches may reconfigure current paths among the light elements and the current regulators, for example, in response to the voltage range detected by a control module. The current limit adaptations may advantageously maintain power dissipation of the linear current regulators at a reduced level across a wide input voltage range, and without generating substantial electromagnetic interference.
