ABSTRACT:
The invention concerns a circuit for setting all types of LED'S (7), mounted in series of five, their particular arrangements in series of five, powered by a direct voltage higher than 14 volts, using an LM 317 T regulator (1) and a potentiometer of 4.7 kOhms (8) providing them with a variable luminance. Complementary setting resistors (R1, R2, R3), are arranged in series or in parallel, on the trigger or at the regulator output, so as to obtain a setting stroke starting form the outset of the illumination that is around 7.5 volts, up to its maximum performance around 12.5 volts. The invention is designed to replace all the applications where fixed LED'S are used.
