Controlling lighting loads to achieve a desired lighting pattern
First Claim
1. A method of controlling a plurality of lighting fixtures to obtain a predefined light profile across a surface, the method comprising:
- retrieving an image of a space;
determining a lighting level for a first sub-area within the space;
determining a lighting level for a second sub-area within the space;
determining a first lighting fixture that affects the lighting level for the first sub-area and the lighting level for the second sub-area;
determining a second lighting fixture that affects the lighting level for the second sub-area; and
adjusting the first lighting fixture and the second lighting fixture to achieve a first target light level in the first sub-area and a second target light level in the second sub-area, wherein the adjustment of the second lighting fixture is in response to an amount that the first lighting fixture affects the lighting level for the second sub-area when the first lighting fixture is adjusted.

Abstract
A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

11. A method of controlling a plurality of lighting fixtures to obtain a uniform lighting level across a surface, the method comprising:
-
retrieving an image of a space; determining a lighting level for a first sub-area within the space; determining a lighting level for a second sub-area within the space; determining a first lighting fixture that affects the lighting level for the first sub-area and the lighting level for the second sub-area; determining a second lighting fixture that affects the lighting level for the second sub-area; and adjusting the first lighting fixture and the second lighting fixture to achieve a uniform lighting level across the first sub-area and the second sub-area, wherein the adjustment of the second lighting fixture is in response to an amount that the first lighting fixture affects the lighting level for the second sub-area when the first lighting fixture is adjusted. - View Dependent Claims (12, 13, 14, 15, 16, 17)
