Embodiment Construction

[0021] As detailed herein, an occupancy-sensitive intelligent lighting system is provided such that when the occupancy of a room changes, the system produces lighting conditions that are most suitable for the current occupancy scenario to optimize comfort and minimize energy consumption . "Occupancy" generally refers to the number and / or spatial distribution of people in a space such as a room, corridor, staircase, enclosure, etc. However, it can also refer to the number and spatial distribution of other types of objects (eg, animals, robots, etc.) that can move in, out of, or around a space and affect lighting. To realize occupancy-sensitive smart lighting, a control strategy module and an occupancy sensing module are implemented, which work in two phases: a sensing phase and a regulating phase. In the sensing phase, the occupancy sensing module collects sensor readings to estimate occupancy; in the conditioning phase, the control strategy module decides what lighting condit...

Abstract

A smart lighting system and method that estimates occupancy using perturbation- modulated light and distributed non-imaging color sensors. A system is disclosed that includes a plurality of non-imaging color sensors; a plurality of color controllable lights; a system that perturbs the color controllable lights within a space; a system that collects resulting color information from the non-imaging color sensors, and builds a light transport model based on collected color information; a system that estimates an occupancy pattern or distribution within a space; and an adjustment module that adjusts the color controllable lights based on the light transport model and a predefined control strategy.

Description

technical field [0001] The subject matter of the present invention relates to intelligent control of lighting in spaces, and more particularly to intelligent lighting systems using perturbatively modulated light and distributed non-imaging color sensors to provide occupancy sensing. Background technique [0002] Intelligent control of lighting (specifically, synthetic lighting) in a space over time in response to variables such as exterior (i.e., natural) lighting changes and room occupancy patterns has the potential to improve energy consumption, human comfort, and well-being sense, as well as benefits in terms of worker productivity. [0003] Existing systems suffer from various deficiencies, including: (1) they often only detect the presence of people, not their number and spatial distribution in the room; and (2) they typically use cameras or other high-resolution sensors, It generates a high computational load for real-time operation and may have significant privacy or...
