Multiple light sensor multiple light fixture control

摘要

Systems and methods are disclosed to control light output at one or more light fixtures based on input from one or more light detectors. Embodiments of the invention may also be used for auto commissioning, personal control and/or day lighting. Some embodiments of the invention can be used to ensure that light output at the light fixtures provides a combined uniform photometric distribution within an architectural space. Moreover, embodiments of the invention can respond to changes to ambient light, which illuminates the architectural space from a window, door, or television, etc., in a smooth and non-oscillating way. Embodiments of the invention can be implemented in lighting systems employing multiple light fixtures having one or more light source and multiple light detectors.

主权项

1. A method for adjusting the light output at a light fixture, the method comprising:
directing a light source to illuminate an architectural space with a light output value; determining a value representing a geometric relationship of the fixture relative to a light sensor, wherein the value representing the geometric relationship is determined from a function of a light contribution measured at an external sensor; adjusting the light output value based on a function comprising the value representing the geometric relationship; and directing the light source to illuminate the architectural space with the adjusted light output value.
