Just how long LED lamp life? General market in general are claims that 50,000 hours, not knowing that 50,000 hours talking about life LED light source, but the overall life after made LED lighting products are generally less than 50,000 hours The specific life expectancy based on the finished lamp power, the greater the power, the higher cooling requirements, if heat is not good, LED's life will be affected. These also are not the main reason for lamp life, as long as power, current does not exceed the tolerance range LED light source itself does not have his life much impact (when the human failure of the light source is not calculated), the main affecting their life or the drive power section, the general LED drive power life in 2--3 years ago. Therefore, LED lighting industry common LED lifetime value of the parameter should be about normal 30,000 hours. Such a life is already meet most lighting needs to go far beyond saving lamp, incandescent lamp life of LED lamps, its price and its cost recovery for electricity in terms of this life have an absolute advantage. That we going to have to blindly pursue a longer life? Is it worth a ponder the question.
 
  Although the standard incandescent lamp life is defined as 1000 hours, but long periods of time civilian home lighting market, the most important reason is the price advantage. I believe that LED lighting has certain advantages after life, there is no need to go too much in pursuit of a longer life, as compared to the price of energy-saving lamps, LED lamps to influence the market price is currently the key to development, LED lighting wants In market share, reduce costs, it is the last word.
 

  Recently, the US Energy Star standards being drafted discussion LED bulb, one of the more controversial point is about the minimum life requirements, EPA will be the consumer may claim lamp life from 25,000 hours to 10,000 hours down to a minimum, because 10,000 hours point with respect to three hours a day to count has nine years of life.
