摘要 |
The invention relates to an apparatus for controlling an illumination device, particularly in an aircraft, which comprises the following: a light source (6) which is suitable for emitting light with a wavelength in the visible range, and a pulse-width modulator (2) which delivers at least one output signal (5) that is connected to the light source (6) and is suitable for effecting brightness control of the light source (6), wherein the output signal (5) is composed from a first number of first subsignals (7) each having a first pulse width (8) and a second number of second subsignals (10) each having a second pulse width (11), which is shorter than the first pulse width (8), so that the brightness of the light source (6) can be adjusted by varying the first number and the second number for a brightness change and the output signal (5) is repeated after delivery of the first number and second number of subsignals (7, 10). The invention also relates to a method for controlling an illumination device, particularly in an aircraft.
