Abstract: Introduces the lumen depreciation characteristics of LED lighting products,
analyzes characteristics curve of LED lighting product's lumen depreciation in relation to
temperature change,and studies the influence of temperature accelerated stress on
lumen depreciation. On this basis, puts forward design and implementation of a LED
product's (hereinafter referred to as the SSL product) temperature accelerated stress life
-monitoring test system,which takes photoelectric parameter automatic collection system
and monitoring test system as the carrier.
Keywords: SSL products; lumen automatic collection; accelerated life; test system
