Abstract
A method for controlling a color temperature of light emitted by a plurality of light-emitting diodes (LEDs) comprises steps of a controlling device entering a transition mode upon receiving a tuning signal from an input device, the controlling device generating a modified signal based on a received electrical signal according to the tuning signal, the controlling device outputting the modified signal to a lighting device, and the controlling device entering a normal mode once a predetermined period of time has elapsed since the last time the controlling device receives the tuning signal.
Claims7
An operation method of a lighting system that includes a controlling device for receiving an electrical signal from mains electricity, and a lighting device connected to the controlling device and including a plurality of light-emitting diodes (LEDs), the operation method comprising steps of:
- outputting, by the controlling device operating in a normal mode, the electrical signal as a control signal to the lighting device;
- entering, by the controlling device operating in the normal mode, the transition mode upon receiving a tuning signal from an input device;
- generating, by the controlling device operating in the transition mode, a modified signal by modifying the electrical signal according to the tuning signal;
- outputting, by the controlling device operating in the transition mode, the modified signal as the control signal to the lighting device;
- entering, by the controlling device operating in the transition mode, the normal mode once a predetermined period of time has elapsed since the last time the controlling device receives the tuning signal;
- and
- setting, by the lighting device, a color temperature of light emitted by the LEDs according to waveform of the control signal.
