LED驱动电源发展的5个主要细节问题

Date: 2013-11-29
Views: 27

 

      1.生产销售组装LED照明及LED相关产品的公司的技术操作工程人员对开关电源和LED驱动电源的了解不够,平常做出的普通电源是可以正常工作,但一些关键性的评估及电磁兼容的考虑不够,还是存在着潜在的隐患;
     

      2.大部分LED电源生产企业都是从普通的开关电源转型过来做LED电源,对LED的特点及使用认识还不够;
    

      3.目前关于LED的标准几乎没有,大部分都是参考开关电源和电子整流器的标准;
     

      4.现在大部分LED电源没有统一,所以量大部分都比较小。采购量小,价格就偏高,而且元器件供应商也不太配合;
     

      5.LED电源的稳定性:宽电压输入,高温和低温工作,过温、过压保护等问题都没有一一解决;
     

      首要问题是驱动电源与电路的整个的使用寿命周期,尤其是相关的关键要害零器件如:电容在高温下的寿命直接影响到电源的寿命; 其次是LED驱动器应应战更高的转换效率,尤其是在驱动大功率LED时更是如斯,由于一切未作为光输出的功率都作为热量耗散,电源转换效率的过低,影响了LED节能结果的发扬; 当前在功率较小(1-5W)的使用场所,恒流驱动电源本钱所占的比重曾经接近1/3,曾经接近了光源的本钱,必然水平上影响了市场的全面推行。
