Lighting control

A controller for controlling at least one luminaire to render lighting scenes in an environment;

• the controller comprising:
• a first input arranged for receiving a first lighting sequence defining a first lighting scene to be rendered in the environment during a first time period, receiving a second lighting sequence defining a second lighting scene to be rendered in the environment during a second time period after the first time period, and receiving a third lighting sequence defining a third lighting scene to be rendered in the environment during a third time period after the second time period;
• a second input arranged for receiving data indicating user presence within the environment;
• an output arranged to control the at least one luminaire;
• and
• a processor arranged for:
• receiving the first lighting sequence, the second lighting sequence, and the third lighting sequence via the first input;
• and
• controlling, via the output, the at least one luminaire to render the first lighting scene in accordance with the lighting sequence during the first time period;
• wherein the processor is further arranged for:
• determining, upon expiration of the first time period, based on data received via the second input, a user presence value within the environment;
• and
• if the user presence value does not exceed a predetermined threshold presence value upon termination of the first time period, controlling, via the output, the at least one luminaire to render the second lighting scene;
• or else,
• extending the first time period and forgoing replacement of the first lighting scene with the second lighting scene during the extension of the first time period:
• and
• determining, upon expiration of the second time period, based on data received via the second input, the user presence value within the environment;
• and
• if the user presence value does not exceed a predetermined threshold presence value upon termination of the second time period, controlling, via the output, the at least one luminaire to render the third lighting scene;
• or else,
• extending the second time period and foregoing replacement of the second lighting scene with the third lighting scene during the extension of the second time period:
• wherein the second lighting scene is different from the first lighting scene, and the third lighting scene is different from the second lighting scene and the first lighting scene.
