PROTOCOLS FOR CODED LIGHT COMMUNICATIONS |
摘要 |
Protocols for coded light communication and control in a lighting system wherein each lighting device transmits modulated light during illumination are proposed. When a first source lighting device need to transmit information across the lighting system to a destination lighting device one or more intermediate lighting devices decode received coded light transmissions from the first source lighting device. The one or more intermediate lighting devices superimposes the coded light transmissions from the first source lighting device with coded light transmissions from a second source lighting device in a broadcast. The first source lighting device uses the received broadcast signal from the one or more intermediate lighting devices to retrieve the coded light transmissions from the second source lighting device by canceling stored a priori known signal components. |
