Operation of an LED luminaire having a variable spectrum

摘要

The invention relates to a method for controlling the operation of an LED luminaire (1) which has a plurality of LEDs (5, 6) as light sources. The method has the following steps:
evaluation, by a control unit (3) for the LED luminaire (1), of an electrical signal which is produced by a switch, pushbutton or dimming switch (10) which can be operated by a user (11) and is connected to the control unit (3) and supplied with voltage via an interface (23) of the LED luminaire (1), andvariation of the color spectrum of the LED luminaire (1) as a function of the evaluated signal.

1. A method for controlling the operation of an LED luminaire which has a plurality of LEDs as light sources, wherein the method has the following steps:
evaluating, by a microcontroller for the LED luminaire, an electrical signal produced by a toggle or pushbutton switch that is operable by a user and that is connected to the microcontroller, the LED luminaire being supplied with a mains voltage via an interface of the LED luminaire, wherein the mains voltage output by the toggle or pushbutton switch supplies the LED luminaire by means of the toggle or pushbutton switch, and varying the color temperature of the LED luminaire as a function of the evaluated signal in which the microcontroller counts the number of times the toggle or pushbutton switch is operated and an energy buffer in the microcontroller counts the time duration of the operation of the toggle or pushbutton switch, wherein the LED luminaire produces white light, and wherein the color temperature of the white light is varied as the function of the evaluated signal.
