Abstract

Es wird eine elektrische/elektronische Einrichtung zur Erzeugung von Farbdarstellungen in größeren Anordnungen mit mehreren auf zumindest einer Leiterplatte vorhandenen LED-Anordnungen vorgeschlagen, bei welcher zur Erzeugung von möglichst gesättigten Farben bei der Farbdarstellung die Auswirkungen von Korrekturen auf die nichtbeteiligten Primärfarben (RGB) so gering als möglich sind und gleichzeitig eine möglichst große Homogenität des von der Anordnung abgegebenen farbigen Lichteindrucks erhalten bleibt. Zu diesem Zweck ist zur Steuerung des farbigen Lichteindrucks ein Algorithmus in den Mikroprozessor der Korrektureinheit implementiert, durch welchen je nach Zusammensetzung des farbigen Lichteindrucks aus den Anteilen der drei Primärfarben (RGB) Rot, Grün und Blau eine Gewichtung der Korrekturdaten derart vorgenommen wird, so dass einzelne der die drei Primärfarben (RGB) darstellenden LED-Elemente der LED-Anordnungen entsprechend des Algorithmus mit den Korrekturen beaufschlagt werden und wobei die durch eine lichttechnische Messung ermittelten Korrekturdaten und Farbmesswerte in den zur Korrektureinheit gehörigen Speicher abgelegt werden. Zudem sollen die durch eine lichttechnische Messung ermittelten Korrekturdaten und Farbmesswerte auf einfache Art und Weise bei der Ansteuerung von größeren Anordnungen jederzeit bedarfsgerecht zur Verfügung gestellt werden können. Zu diesem Zweck sind die Korrekturdaten und die Farbmesswerte wieder auslesbar in dem Speicher der Korrektureinheit abgelegt und ist jede Leiterplatte zur Weiterleitung der Korrekturdaten und Farbmesswerte mit zumindest einer mit dem Mikroprozessor und dem Speicher elektrisch in Verbindung stehenden Anschlussschnittstelle versehen.

Figure imgaf001
There is proposed an electrical / electronic device for generating color images in larger arrangements with a plurality on at least one printed circuit board LED assemblies, in which to produce the most saturated colors in the color representation, the effects of corrections on the uninvolved primary colors (RGB) so low are possible and at the same time the greatest possible homogeneity of the colored light impression emitted by the arrangement is maintained. For this purpose, an algorithm is implemented in the microprocessor of the correction unit for controlling the colored light impression, by which depending on the composition of the colored light impression of the proportions of the three primary colors (RGB) red, green and blue weighting of the correction data is made such that individual of the three primary colors (RGB) representing LED elements of the LED arrays are subjected to the corrections according to the algorithm and wherein the determined by a photometric measurement correction data and color measurements are stored in the memory belonging to the correction unit. In addition, the correction data and color measurement values determined by a photometric measurement should be able to be made available at any time in a simple manner in the control of larger arrangements at any time. For this purpose, the correction data and the color measurement values are again stored in the memory of the correction unit and each printed circuit board is provided with at least one connection interface that is electrically connected to the microprocessor and the memory for forwarding the correction data and color measurement values.
