Energy Saving Lamp Attenuation Compensation Based On LED Control System Research

Street lighting is one of the most important municipal roadway lighting equipment,to protect the urban road traffic flow,improve the efficiency of traffic and transport,to improve urban life quality and environment plays a vital role in such areas.But lamps to provide people with convenient and efficient but also in a large number of consumed electricity.Due to the size effect on the street so large electric equipment is improved even if a small unit can also bring great benefits to the effective monitoring and management of street lighting can bring significant energy saving effect,the traditional design of street lamp control,and no research on energy saving control for special light source,light source control links caused in the unnecessary power consumption and waste.Combined with the current development trend of energy-saving light source and information network,it is imperative to study the energy-saving control of the street light source control.Primarily,to analyze the characteristics of LED mechanism,LED parameters for the optical properties,electrical properties,thermal properties and these properties are analyzed and introduced,and research LED decay failure model,a detailed analysis of the various failure modes of LED attenuation effect,through theoretical research to find out the factors such as temperature,LED decay humidity,voltage and current,to establish a mathematical model by using the artificial neural network method ANN,detailed interpretation of the LED light failure model.Secondly,according to the characteristics of LED mechanism and failure model,selected for the study object control model,make the appropriate expansion and change and on this basis,the attenuation of static compensation control model based on dynamic compensation control mode,led light.The two control modes are described respectively,including the description of control methods,the design of control process and the control characteristics.That the light attenuation and the static compensation dynamic compensation is indispensable and light complement each other.Finally,according to the control strategy of static and dynamic light attenuation compensation compensation,design a set of LED attenuation compensation lamp control system,completed the LED power driver and dimming control circuit,attenuation compensation control module design,the introduction of the ZigBee wireless network control protocol,network technology and other core technologies,the street lights energy saving system of embedded wireless control function,realize the wireless control system of energy-saving lamp.In order to realize the LED energy demand,the LED decay characteristics were studied by using the method of dynamic light compensation and static compensation,made according to the design of energy saving control system of light attenuation compensation results,proved that the dynamic control system of energy saving effect is remarkable conclusion.
