US standards for LED product testing
I. Overview The current US criteria and standards for SSL products are: 2. Apply for the “Energy Star†certification requirements and procedures – a guide for manufacturers to certify ENERGY STAR SSL products. 4. Standard for lumen maintenance measurement (LM80 method for measuring LED light source maintenance approval) Please download the full text according to your three-party forum password. 48V25Ah Lithium Ion Battery,48V25Ah Lifepo4 Battery,48V Lithium Battery For Electric Scooter,48V25Ah Lithium Battery Pack Jiangsu Zhitai New Energy Technology Co.,Ltd , https://www.ztbatteries.com
1. DOE SSL criteria (criteria):
1) Criteria for qualifying for 2007.7:
a. color (unified indicator)
b. Electrical (unified indicator)
c. Four indoor, three outdoor lighting 2) Supplementary provisions for Class A of 2008.8:
Four indoor, six outdoor lighting.
1) Manufacturer's submission list;
2) providing the process;
3) Pre-certification activities---determine laboratory lamps for photoelectric and temperature tests, and create product groups;
4) Submitting process - the process of online submission;
5) Test---temperature test, lumen maintenance test;
6) Annex A
3. Photoelectric parameter detection standard (Electrical and photometric measurement methods approved by LM79 solid-state lighting products) LED light sources and lamps are different from traditional light sources and lamps, and the measurement methods are naturally different. Examples: LED line spectrum, continuous spectrum of traditional light sources.
The measurement method must be specified in order to have the correct measurement results, obtain reliable data, and establish a comparative basis.
The life of the LED is called tens of thousands of hours, but because 1) there is no accelerated aging test;
2) The LEDs of the same chip factory have different life spans in each product;
3) the lifetime is related to the ambient temperature of the lamp;
You must have a long but unified approach.
