Claim:
1. A method of calibrating light output of a plurality of LEDs, comprising: determining a distance value of an object from each of a plurality of distance sensors in a space, each of said distance sensors associated with at least one LED of a plurality of LEDs; comparing said plurality of distance values to determine a layout of said space; grouping each of a plurality of said distance values in said space into one of at least a first distribution and a second distribution, said distance values of said first distribution indicative of larger distances than said distance values of said second distribution; setting light output characteristics of a first LED group of said LEDs in accordance with floor lighting characteristics based on said first LED group being associated with said distance sensors having said distance values in said first distribution; and setting light output characteristics of a second LED group of said LEDs in accordance with workplace lighting characteristics based on said second LED group being associated with said distance sensors having said distance values in said second distribution.
