摘要:
A circuit for a lighting device comprises a sub-circuit which comprises a series current regulator and a group of solid state light emitters. The current regulator and the solid state light emitters are arranged in series. In some embodiments, the circuit further comprises a fan electrically connected in series in the sub-circuit. In some embodiments, the circuit further comprises a second sub-circuit which comprises a second series current regulator and a second group of solid state light emitters, the first sub-circuit and the second sub-circuit being arranged in parallel. In some embodiments, an anode of the series current regulator is electrically connected to a cathode of one of the solid state light emitters. Also, methods of lighting wherein a sum of voltage drops across light emitters and a current regulator is in the range of from 1.2 to 1.6 times the line voltage.
