Pocket lamp with at least one light diode has an oscillator coil for receiving electromagnetic radiation and a rectifier to convert this into dc or pulsed current for the diode

摘要

A pocket lamp (1) comprises at least one light diode (6), an oscillator coil to receive electromagnetic radiation and a rectifier circuit (4) to power the diode by converting the radiation into DC or pulsed current. There is a circuit (3) to bring the coil (2) into resonance with a transmitted radio wave or surrounding radiation.
