摘要
发光二极管是一种日益应用广泛的节能环保照明器件,随着其成本的下降和各国对低效灯具的限制,它的市场需求更将逐步增加,这是照明技术的发展方向。该文在介绍了发光二极管和加速寿命试验的发展历史的基础上,综述了适用于发光二极管的两种试验,分析了发光二极管的失效机理,展望了其寿命预测技术的发展趋势和前景。
LED is an increasingly used lighting device for energy saving.As its costs decline and national restrictions on inefficient lighting,it is more market demand will gradually increase.It is a direction for lighting technology s development.Based on briefly presenting the history of LED and the accelerated life test,this paper mainly introduces the test which is applicable to the LED,and analysis the failure mechanism of LED,then summarized the technology s development trends and prospects.
