摘要
In lightning display with (3) light-emitting elements driven by the control voltage, the voltage drop in the feed line for feeding on the light emitting elements of two or more can be compensated. For this purpose, using the known resistance of the current to (3) light-emitting elements all connected to the feed line one, the potential profile of the feeder line (20) is calculated. Control voltage for (3) the light emitting element is changed in consideration of the actual potential of the feed line (3) With respect to each element (20). Thus, variation in brightness of the lightning display resulting from the potential difference can be prevented. One element of the lightning display (3), current control means (8), and (6), light emitting means signal holding means, means for interrupting the flow of current (8) light emitting means (4), (12) I have a. In order to be adjusted in a state in which a current is interrupted, the control voltage is not present potential difference Feedline. Signal holding means (6) holds the control voltage based on the voltage on the line at the position of each light-emitting element (3). Lightning display has an adjustable voltage for (20) and the power supply line. Voltage is chosen sufficiently high minimum voltage required for setting the desired current through (3) the light emitting element is to be achieved.
