Research On The Reliability Prediction Of Solar LED Lighting System

Sustainable development is an important issue for human beings in this century,and the energy problem is an urgent problem to be solved.The most effective way to solve energy shortage is to develop new energy and improve energy efficiency.As a clean and pollution-free green energy,solar energy has been more and more widely used.In recent years,solar LED lighting products are widely used because of its energy saving and environmental protection and long life of light source.With the solar LED lighting system technology development and popularization of the application,property warranty,life relates to the reliability of products has attracted more and more attention,and become a key indicator to measure the quality of the system.Therefore,the research on the reliability of solar LED lighting system can not only enrich the design theory,but also improve the reliability level of the system.Aiming at the reliability problems of solar LED lighting system,based on the analysis of the solar LED lighting system on the working principle,working time and the control switch hypothesis of solar lighting system components of the working life are subject to exponential distribution,the random variables are independent of each other and the internal components of each subsystem for the reliability of series structure conditions,according to the the working principle and the reliability function structure of electricity complementary solar LED lighting system,applying relevant knowledge of three branch automatic dispatching system and the Markov process,the reliability of the system of LED lighting system: the first is the analysis of control system of two kinds of different effects of the entire system,the cold warm standby reliability model of solar lighting the system,and then the reliability index system in cold warm standby condition,such as the mean time to first failure;followed by the introduction of maintenance and other external conditions,the maintainability model of the system is established,and gets the reliability index;the third is based on the analysis of the cold standby model the probability distribution of each branch fault;finally,the model is applied to a certain brand of solar LED lighting products,the key components of solar LED the illumination subsystem reliability data collection,data reliability prediction subsystem level,and according to the analysis results of Chinese climate region clustering and lighting products work set time,estimating the parameter ofruntime ratio,finally according to the reliability index of the model in different regions,verifying the correctness and applicability of the model the.Solar LED lighting system reliability and maintainability model and establishes the functional relationship between generally applicable to solar LED lighting products system,unit,component and system reliability,and fault probability distribution of solar LED lighting system has made the preliminary discussion,to carry out reliability and distribution can be expected to become in the product development process also,suitable for predicting product installation trend after the use of reliability and provides a theoretical basis for making scientific maintenance strategy for customer service.The research work of this paper has a good reference value for the research on the system reliability of solar air conditioning and other similar products.
