RF controlled sequential lighting system
First Claim
1. A sequential lighting control system controlled by radio frequency (RF) signals, comprising:
- a motion sensor, a light controller and associated lights located on each level of a stairwell for detecting the presence of one or more persons in the stairwell and sequentially lighting individual levels of said stairwell when needed;
wherein a first motion sensor that detects the entry of a person into a first level of a stairwell sends an RF signal to a first RF receiver in a first light controller that controls lights in that level of said stairwell, said controller activating said lights in response to said RF signal;
said first light controller transmits an RF signal to light controllers on immediately adjacent levels of said stairwell, which light controllers upon receiving said signal activate lights on the immediately adjacent levels of said stairwell;
said adjacent level motion sensor detects movement of one or more persons ascending or descending the stairwell and signals the respective light controller on the next adjacent level such that the controller at that level signals controllers on further adjacent levels to activate their respective lights, such that lights in the stairwell are activated in sequential manner until the one or more persons exit the stairwell.

Abstract
An RF controlled lighting system that activates lights in adjacent spaces when a person walks into a first space and then traverses the spaces in sequence. A detection device senses the entry of a person into a first space controlled by the system. A micro-controller activates the lights in that space for immediate light and in the adjacent spaces in preparation for the person to traverse the spaces in either direction from the origin space. As the person traverses the contiguous spaces, controllers in each space sense the person'"'"'s presence and communicate by RF signals to activate lights along the person'"'"'s path. The controllers extinguish their lights a predetermined time after the person passes or no one enters a space.

4. A sequential lighting control system comprising:
-
a first transceiver in a first controller communicating with a first light that receives a first activation signal to activate said first light, commands activation of said first light, and transmits a second activation signal to a second transceiver in a second controller to activate a second light; said second transceiver communicating with a second light and receives the second activation signal to activate said second light, commands activation of said second light, and transmits a third activation signal to activate a third light; said third transceiver communicating with a third light and receives the third activation signal and commands activation of a third light. - View Dependent Claims (5, 6, 7, 8, 9, 10)
