Vertically integrated LED maker Lextar Electronics Corp of Hsinchu,Taiwan says that its"Photometric Laboratory"has received LM-79 and LM-80 accreditation.According to the firm,this makes Lextar the first LED corporation in Taiwan to be awarded both accreditations.
LM-80 is the Lumen Maintenance assurance for LED packaging.LED lumens(brightness)decay over time,producing light fades or colorcast.LM-80 tests LED packaging at multiple temperatures for 6,000 hours to determine the quality and life of a particular LED.Major international plants at present all use LM-80 as indicators for the quality and life of their LED packages,making it a common testing standard across the globe,says Lextar.
LM-79 is the industry standard procedure for photometric and electrical measurements for LED lighting products.LED lamp manufacturers can test and report through LM-79 to provide an optical measurement value of credibility.
To receive the LM-80 accreditation,Lextar's 3014 and 5630 LED packages exceeded 6,000 hours of testing over the course of nearly 9 months,and demonstrated a high standard luminous output when subjected to temperatures at 55 and 85 degrees Celsius.The 3014 and 5630 packages offer a high degree of stability and quality,and can be used in bulbs,tubes,down lights,panel lights,advertising light boxes as well as in many other applications.
Lextar's CoB product series is also undergoing LM-80 testing,with accreditation expected next year.
