Abstract (en)
[origin: EP2326144A1] The device comprising a set of LEDs arranged in a set of ramps. Each ramp comprises another set of LEDs arranged in series. A step-up converter circuit (DCM) generates high voltage from low direct current (DC) voltage. An analog servo control device (D.A) comprises an operating mode, where one of the modes is defined by an electronic addressing of the high voltage. The servo control device comprises servo control electronic circuits (C.A.k) linked to an electronic multiplexer (MUX). Each servo control electronic circuit is operated when the operating mode is selected.
