Abstract (en)
[origin: EP1289341A2] The circuit has two supply terminals, a resistance circuit (1), a diode circuit (2) and one or more LEDs (31,32). The inputs (15,16) of the resistance circuit are directly coupled to supply terminals. To the outputs of the resistance circuit are linked the inputs (25,26) of the diode circuit, and the series-coupled LEDs are connected to the outputs of the diode circuit. Preferably the resistance circuit contains several parallel-connected branches. Independent claims are included for a circuit board and for car lamp.
