SYNCHRONIZED LIGHT CONTROL OVER A WIRELESS NETWORK
First Claim
1. A light control and data interface module, comprising:
- one or more processors;
a transceiver configured to receive a first communication signal from one or more sensor modules, the first communication signal including an indication of an identity of the one or more sensor modules and a first elapsed time since a triggering event was detected by the one or more sensor modules; and
a non-transitory, computer readable medium storing instructions that when executed by the one or more processors cause the one or more processors to;
receive the first communication signal from the transceiver;
determine a delay time to trigger a lighting control response based on a difference between a desired delay time to trigger the lighting control response and the first elapsed time; and
transmit a command signal that implements the lighting control response to a power converter coupled to the light control and data interface module after the delay time to trigger the lighting control response has elapsed, wherein the power converter is configured to supply an electrical current to an LED based light engine in response to the command signal.

Abstract
A light control and data interface module (LCDIM) is used to control an LED based illumination device. The LCDIM includes a transceiver that receives communication signals from one or more sensor modules. The signals may include an indication of an identity of the one or more sensor modules and elapsed time since a triggering event was detected. One or more processors are configured to receive the communication signal and to determine a delay time to trigger a lighting control response. The one or more processors are further configured to cause the transmission of a command signal to a power converter coupled to the LCDIM to implement the lighting control response.

17. A mobile communications device, comprising:
-
one or more processors; a camera module configured to capture one or more images of a plurality of LED based illumination devices within an environment; and a non-transitory, computer readable medium storing instructions that when executed by the one or more processors cause the one or more processors to; identify a presence of the plurality of LED based illumination devices based on the one or more images; and communicate a signal indicative of at least one light control rule to each of the plurality of LED based illumination devices, wherein the at least one light control rule is indicative of a desired lighting response of each of the plurality of LED based illumination devices to a signal received from the sensor module indicative of a triggering event detected by a sensor module. - View Dependent Claims (18, 19)
