Abstract
Official abstract text for this publication.
A method for adjusting the color point of a lighting unit including semiconductor-based lasers for generating an RGB signal. The method may include supplying at least one component of the RGB signal to a sensor via a filter; and actuating at least one of the semiconductor-based lasers by means of a signal detected by the sensor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for adjusting the color point of a lighting unit comprising semiconductor-based lasers for generating an RGB signal, the method comprising: supplying at least one component of the RGB signal a sensor via a filter; and actuating at least one of the semiconductor-based lasers is by means of a signal detected by the sensor, wherein a plurality of semiconductor-based lasers are actuated sequentially by means of the respectively associated dete…
