Notification lighting control

A method for controlling a plurality of light sources of a lighting system comprising, the plurality of light sources comprising notification light sources and background light sources, the method comprising:

• receiving notification light settings that are to be supplied to one or more of the plurality of light sources assigned as notification light sources by the notification light settings to provide a visual notification of an event that are transmitted from a notification service;
• comparing background light settings with the notification light settings in order to determine, based on a predetermined threshold, whether sufficient contrast will be provided;
• and
• determining based on said comparison that one or more of the background light settings and the notification light settings are to be modified such that the contrast between the background light settings and the notification light settings is enhanced;
• wherein in response to determining that the received notification light settings are to be modified, the method further comprising modifying the received notification light settings to generate modified notification light settings, and controlling the one or more notification light sources in accordance with the modified notification light settings, and
• wherein in response to determining that the background light settings are to be modified, the method further comprising modifying the background light settings to generate modified background light settings, and controlling background light sources in accordance with the modified background light settings.

A computer program product for controlling a plurality of light sources of a lighting system, the plurality of light sources comprising notification light sources and background light sources, the computer program product comprising code embodied on a non-transitory computer-readable medium and being configured so as when executed on a processor to:

• receive notification light settings that are to be supplied to one or more of the plurality of light sources assigned as notification light sources by the notification light settings to provide a visual notification of an event that are transmitted from a notification service;
• compare background light settings with the notification light settings in order to determine, based on a predetermined threshold, whether sufficient contrast will be provided;
• and
• determine based on said comparison that one or more of the background light settings for the background light sources and the notification light settings for the notification light sources are to be modified such that the contrast between the background light settings of the background light sources and the notification light settings of the notification light sources is enhanced;
• wherein in response to determining that the received notification light settings are to be modified, modify the received notification light settings to generate modified notification light settings, and control the one or more notification light sources in accordance with the modified notification light settings, and
• wherein in response to determining that the background light settings are to be modified, modify the background light settings to generate modified background light settings, and control background light sources in accordance with the modified background light settings.
