Abstract
Aspects comprise apparatus and methods for wirelessly powered lighting products. One aspect comprises an apparatus that generates light from a wirelessly coupled power source. The apparatus comprises a first conductive loop configured to enclose an area, the first conductive loop configured to resonate and generate an induced current when excited by a magnetic field generated by a transmitter. The apparatus further comprises a first set of one or more capacitive elements coupled to the first conductive loop, the coupled first conductive loop and first one or more capacitive elements configured to form a first resonant circuit. The apparatus also comprises a first set of one or more lighting devices integrated with the first conductive loop, the first set of one or more lighting devices each configured to generate a light based on the induced current that flows through the first set of one or more lighting devices.
