Abstract
This light emitting element comprises three differently colored luminous sources the excitation of which varies as a function of a signal developed by a physical phenomenon sensor, in particular a microphone. The analog signal emitted by the sensor is initially converted into a sequence of electrical pulses in a suitable converter. The leading edges of said pulses are next applied to a counter the output of which provides a coded signal which changes with the arrival of each such edge and thus determines a different state of excitation of the luminous sources. The arrangement as described enables changing the color of the element from a musical signal.
