Abstract
A vending machine includes a controller coupled to at least one light emitting diode (LED) light strip mounted within the vending machine and illuminating an interior thereof. The LED light strip includes an input terminal that receives one or more signals corresponding to a mode of the LED light strip, an LED mounting board supports a plurality of LED chips forming a plurality of independent circuits each including a serially-connected subset of the LED chips, and electrical circuit components (resistor, input terminal, and/or output terminal) that cause the respective circuit to function independently from remaining circuits in the LED light strip. The controller selectively powers one or more of the independent circuits in the LED light strip to meet either a power consumption requirement or an illumination output specification, leaving off any remaining independent circuits not corresponding to the specified mode.
