In a calibration of a lighting system with at least one light source and a light source driver, and a light source driver controller controlling the light source driver, separate components are calibrated separately before combining them. For this purpose, the light source is coupled with a light source memory, the light source is calibrated by determining a light source operational relationship between a light source input parameter and a light source output parameter, and light source control data representative of the light source operational relationship are stored in the light source memory. The light source driver is coupled with a light source driver memory, the light source driver is calibrated by determining a light source driver operational relationship between a light source driver input parameter and a light source driver output parameter, and light source driver control data representative of the light source driver operational relationship are stored in the light source driver memory. After these separate calibrations, the light source is assembled with the light source driver, and the light source driver controller is calibrated on the basis of the light source control data and the light source driver control data read from the light source memory and the light source driver memory. If a sensor is used in the lighting system to sense the light produced by the light source, the sensor is coupled with a sensor memory, the sensor is calibrated by determining a sensor operational relationship between a sensor input parameter and a sensor output parameter, and sensor control data representative of the sensor operational relationship are stored in the sensor memory. After assembling the sensor with the light source and the light source driver, the light source driver controller is calibrated further on the basis of the sensor control data read from the sensor memory.
Description
technical field [0001] The invention relates to a method of calibrating a lighting system and a lighting system calibrated according to this method. The lighting system comprises at least one light source for converting electrical energy into light and at least one light source driver having suitable characteristics for supplying electrical energy to the light source. Background technique [0002] In a lighting system, light of one color may be produced by one or more light sources, and light of multiple colors may be produced by combining light emitted from different light sources, each of which emits a different primary color. The different light sources may be of the same or similar type, or may be of different types. [0003] The term "light source" should be understood to include, but is not limited to, any one or more of a wide variety of radiation sources, such as LED (Light Emitting Diode) based light sources (comprising one or more LEDs), incandescent light sources...
