<p>The illuminator (1) has a light emitting diode (11) as an illumination unit, and a digital-analog converter (9), where the flow rate is dependent on analog output signal of digital-analog-converter by light emitting diode. A control interface (5) is connected to logical circuit (7), with which input signals are supplied to the logical circuits. The input signals are converted into logical signals by the logical circuit. The logical signals are supplied to the digital-analog-converter.</p> |
