Optical Maintenance LED Testing Equipment Measure:

Illuminance Maintenance curve, factor and data: lx VS timeLuminous Intensity Maintenance curve, factor and data: cd VS timeLuminous Flux Maintenance curve, factor and data: lm VS time (With Integrating Sphere)Feature:• Freely set the time interval and time extent for automatic measurement• LCD Display, connect with PC via RS232 and English version software. • The test results can export Excel or PDF format and easy to comparing. It can be saved by LS280 software or by USB directly.• The engineer can do LED life analyzes based on the LS280 test results.• LS280 worked with High Power LED Aging Test (LS600), Multiplex Temperature Test (TMP-8/TMP-16) and High and Low Temperature & Humidity Chamber (GDJS-*B), it can do Flux VS Temperature VS Time, which is a perfect instrument system to meet LM-80 request.Specification:• The standard LS280 has 1 Group which has 8 channels. That’s mean LS280 can measure 8 LED products at one time. (Optional: it can be expanding to 8 Groups which can test 64 LED products at one time)• Illuminance: 0.100lx~400klx. Accuracy: ±(2.0%+0.5)• Luminous Intensity: 10mcd~40kcd. Accuracy: ±(2.0%+0.5)• Luminous Flux: 10mlm~9,999,000lm (Depend on the size of integrating sphere). Accuracy: ±(2.0%+0.5)• Maximal Time Range: 9999h/59m/59s• Precision of Timer: ±1s/10h
