Three different LED intelligent lighting architectures are analyzed and four interoperability support elements are extracted.Three levels of lighting interoperation modes that can be utilized in LED intelligent lighting system are discussed based on these elements and the characteristics of lighting interoperation modes are compared under the criteria of real-time performance,reliability and scalability.Suitable scenarios for each mode are obtained,that is helpful for promoting the formulation of unique intelligent lighting standards and more LED intelligent lighting products can be developed to meet consumers demands.
