Devices comprise first and second terminals (1,2) connected to first load circuits (21) comprising first light emitting diodes, and third and fourth terminals (3, 4) connected to second load circuits (22) comprising second light emitting diodes, first connections (11) that interconnect the first and third terminals (1, 3), second connections (12) that interconnect the second and fourth terminals (2, 4), at least one of the first and second connections (11, 12) being a power dissipating connection, at least one of the first and second load circuits (21, 22) being adapted to receive first power from a source (31) via the first and second connections (11, 12), and capacitors (41) coupled in parallel to the second load circuits (22) for storing energy received via elements (42) with current-direction-dependencies and for providing second power to at least the second load circuit (22). |
