摘　　要：利用简易照度计测量LED结温,搭建了非接触式大功率白光LED结温测量实验装置.结果表明:恒流驱动下,大功率白光LED的结温和照度值存在较好的线性关系.A Non-contact experimental device to measure the junction temperature of high power white LED was set up by using a simple illuminometer. The results showed a good linear relationship between the junction temperature and illumination value of high power white LED driven by constant electric current.
