摘要
针对LED照明杂散光的形成原因和处理方法,以及LED照明系统散热问题的产生和结温对灯具寿命和发光率的影响,完善LED照明灯具的设计,利用照明灯具的特点,以目前LED照明灯具采用的散热方式和杂散光的处理形式为基准,采用对比测试的方法对灯具样品进行检验测试。通过对检测结果的分析,解决了LED照明的散热设计中涉及到的关键问题。
According to the causes and treatment of stray light,dissipation problem and junction temperature influence on the lamp lifetime and emission rate for LED lighting system,the author improved the design of LED lighting. Using the characteristic of lighting lamps and taking the heat and stray light treatments of current LED lighting as basis,lamp samples were tested by the comparison test method. Through analyzing the test results, the author solved the key problems involved in the thermal design of LED lighting.
