APPARATUS FOR CONTROLLING LIGHTING PARAMETERS BASED ON TIME OF DAY AND/OR AMBIENT LIGHT CONDITIONS AND RELATED METHODS

摘要

Disclosed is a lighting unit (10) that utilizes sensor data to select a fade-in or fade-out profile for one or more light sources (12). The lighting unit includes a clock module (20), an ambient light level sensor (18), and a controller (16). The controller receives ambient light level data from the ambient light level sensor and time of day data from the clock module, and utilizes the received information to automatically select a fade-in or fade-out profile. The controller can also use the received ambient light level data to calibrate the clock module.

1. A lighting unit comprising:
at least one light source, wherein a property of light emitted from said at least one light source is adjustable; a clock module; and a controller operably connected between said light source and said clock module; an ambient light level sensor configured to sense ambient light level, wherein the controller is operably connected between said light source and both of the said ambient light level sensor and the dock module; wherein the controller is configured to receive time of day data from said clock module; wherein the controller is configured to automatically select a fade-in or fade-out profile for said property of light based at least in part on said time of day data, and wherein said controller is configured to utilize ambient light data from said ambient light level sensor to calibrate said clock module.
