COMMUNICATION PROTOCOL FOR LIGHTING SYSTEM WITH EMBEDDED PROCESSORS AND SYSTEM OPERATING WITH THE PROTOCOL
First Claim
1. A system, comprising:
- a lighting unit, including,a lighting driver, anda lighting module supplied with power by the lighting driver, the lighting module including,one or more light sources,one or more sensors for sensing data indicating one or more operating parameters of the lighting module, anda secondary processor configured to receive the sensed data indicating the one or more operating parameters of the lighting module;
an optical isolator; and
a primary processor configured to monitor the one or more operating parameters of the lighting module,wherein the primary processor and the secondary processor communicate with each other via the optical isolator according to a message-based communication protocol wherein each message communicated between the primary processor and the secondary processor has an identical message format and includes a command field and a response field wherein the response field is provided for indicating a response to a command.

Abstract
A system (100, 200, 300) includes a lighting unit (120, 320, 320), an optical isolator (220, 320) and a primary processor (110, 210, 310). The lighting unit includes a lighting module (250, 350), and a lighting driver (240, 340) supplying power to the lighting module. The lighting module includes: one or more light sources (252-1/252-2, 352-1/352-2), one or more sensors (254, 354) for sensing data indicating one or more operating parameters of the lighting module, and a secondary processor (156, 256, 356) receiving the sensed data. The primary processor and the secondary processor communicate with each other via the optical isolator according to a message-based communication protocol wherein each message communicated between the primary processor and the secondary processor has an identical message format (500) and includes a command field (530) and a response field wherein the response field (550) is provided for indicating a response to a command.

13. A method, comprising:
-
at a secondary processor embedded in a lighting module that includes one or more light sources, receiving from a primary processor a first message communicated according to a message-based communication protocol wherein each message communicated between the primary processor and the secondary processor has an identical message format and includes a command field and a response field wherein the response field is provided for indicating a response to a command; executing a first operation at the lighting module in response to a first command included in the command field of the first message; and sending from the secondary processor to a primary processor a second message according to the message-based communication protocol, wherein the second message includes in the response field a first response to the first command received in the first message. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
