<p>A module comprises first inductor portion (12A), second inductor portion (12B), and at least one light emitting diode (10), the first inductor portion, the second inductor portion and the at least one light emitting diode being arranged such that the module is operable to receive electrical energy wirelessly via the first inductor portion from a third inductor portion, is operable to route current through the at least one light emitting diode, and is operable to transmit electrical energy wirelessly via the second inductor portion to a fourth inductor portion. A plurality of such modules may be contained within a translucent portion, which may be a translucent filler material, to form a lighting system. Electronic circuitry comprises a first set of electrical components (20)connected in parallel with a second set of electrical components (22), the first set of electrical components including at least one light emitting diode (10) and a resistor (24) in series and the second set of electrical components including at least one diode, wherein the first set of electrical components is configured to conduct current only when a voltage across the first and second sets of electrical components is above a first level, wherein the second set of components is configured to conduct current only when a voltage across the first and second sets of electrical components is above a second, higher level, and wherein, when the voltage across the first and second sets of electrical components is at a third level higher than the second level, the resistance of the first set of electrical components is higher than the resistance of the second set of electrical components, such that the current-voltage curve of the second set of components intersects the current-voltage curve of the first set of components when the voltage is at the third level.</p> |
