Switch for controlling LED, has switching devices providing currents for diode arrangements, and logic device controlling devices such that current for corresponding arrangement is not provided at same time

摘要

The arrangement has two light emitting diode arrangements with switching devices e.g. transistor that provide operating currents for the arrangements. The switching devices are switched off and on such that the two diode arrangements glow with given brightness. A logic device (1) is provided for controlling the switching devices such that respective operating current for corresponding arrangements is not provided at the same time. An independent claim is also included for a method for simultaneous operation of light emitting diodes.
