Guoxing Optoelectronics 0.5W-P3528TOP LED white light series products completed the LM-80-2008 standard 6000 hours test on March 15, 2014 (test completion date) by the third-party authoritative testing and certification organization TUV Lab (TUVSUD).
In this test, the 6000-hour lumen maintenance rate of 0.5W-P3528 white light products was 98.66%@55°C, 98.96%@85°C, and 97.89%@100°C, according to the life estimation method specified by IESTM-21, and the estimated life was reached ( 50000~60000) hours, indicating that the life of this product can be publicized for more than 36,000 hours.
Up to now, our company has four white LED device products through the authority LM-80 standard life test is more than 36000 hours: 0.06W-3528 series, 1W-6070 high power series, 1W-ceramic 3535 series, 0.5W-P3528 series.
The LM-80 is the IESNA (North American Institute of Lighting Engineering) approved lumen maintenance rate (LED lifetime) standard. The LM-80 test focuses on components of the light source, including LED packages , arrays, and modules, and uses this data to estimate component life. Manufacturers of LED lights, light engines and LED luminaires are required to obtain the ENERGY STAR certification issued by the US Environmental Protection Agency, and the devices used in their products must meet the requirements of the LM-80 standard test.
The test report is excerpted as follows:
Pipe fittings are the general name of the parts and components that play the role of connection, control, change direction, shunt, seal and support in the pipeline system. A pipe fitting is a part that joins pipes into a pipe.
It mainly includes the following:
1. Pipe fittings used for connecting pipes with each other are: flange, splice, pipe hoop, clamp, sleeve, throat hoop, etc.
2. Pipe fittings that change the direction of the pipe: elbow and bend.
3. Pipe fittings for changing pipe diameter: reducing pipe (reducing pipe), reducing elbow, branch pipe table and reinforcing pipe.
4, add pipe branch fittings: three, four.
5. Pipe fittings for pipeline sealing: gasket, raw material belt, thread hemp, flange blind plate, pipe plug, blind plate, head, welding plug.
6. Pipe fittings for pipe fixing: clasp, hook, lifting ring, bracket, bracket, pipe card, etc.
