Abstract

In some examples, a dimming protocol detection technology includes methods and apparatuses. In other examples, the technology includes a dimmer configured to transmit a dimming input signal. The dimming input signal is in a dimming protocol. The technology further includes a light fixture. The light fixture includes a plurality of lights and a dimming protocol detection module configured to detect the dimming protocol received in the dimming input signal. The dimming protocol is detected from a plurality of dimming protocols. The light fixture further includes a light dimming control module configured to control the plurality of lights based on the detected dimming protocol.

Claims

1. A system for controlling a plurality of light fixtures, comprising:

a dimmer configured to transmit a dimming input signal, the dimming input signal being in a dimming protocol; and

a plurality of light fixtures, each light fixture comprising;

a plurality of lights,

a dimming protocol detection module that automatically detects in real time at least one parameter of the dimming protocol received in the dimming input signal, the dimming protocol being detected from a plurality of dimming protocols, and

a light dimming control module that automatically reconfigures to match the detected dimming protocol based on the at least one parameter to control the plurality of lights based on the detected dimming protocol.

2. The system of claim 1, further comprising the dimming protocol detection module further configured to select the dimming protocol from a plurality of dimming protocols based on one or more parameters associated with the plurality of dimming protocols.

3. The system of claim 2, wherein the plurality of dimming protocols comprises a 0-10 volt lighting control, digital addressable lighting interface (DALI), digital multiplex (DMX512) lighting interface, a remote device management (RDM) interface, or any combination thereof.

4. The system of claim 2, wherein the one or more parameters associated with the plurality of dimming protocols comprise a physical layer parameter, a network layer parameter, or any combination thereof.

5. The system of claim 4, wherein the physical layer parameter comprises a voltage parameter, a current parameter, an isolation parameter, or any combination thereof.

6. The system of claim 4, wherein the network layer parameter comprises a communication protocol parameter, a command format parameter, or any combination thereof.

7. The system of claim 1, wherein the dimming input signal is received from a dimmer.

8. The system of claim 1, further comprising:

the dimming protocol detection module automatically detects in real time at least one parameter of a second dimming protocol received in the dimming input signal; and

the light dimming control module further configured to automatically reconfigure to match the detected second dimming protocol based on the at least one parameter to control the plurality of lights based on the detected second dimming protocol.

9. The system of claim 8, wherein the light dimming control module further configured to automatically discontinue control of the plurality of lights based on the detected dimming protocol in real-time with the detection of the second dimming protocol.
