Product Description
LED-80 LED Granular reliability life accelerated test system
I. Function overview
Such test system fully meets the requirements of IESNA LM-80-2008 and the Energy Star, it monitors real-time optical parameters, electric parameters and housing temperature of LED component and other products under various temperature and stress conditions, and processes the data, presents the aging curve, and provides the life expectation under such accelerated stress according to the Arrhenius theory.
II. System structure
1) The structure of such system consists of a three-in-one high temperature test chamber and a measurement & control system separately;
2) All the three test chambers adopt independent temperature control system and independent temperature inner circulation system; each test chamber is with 6 built-in testing zones, each testing zone is set up with 5 LED test stations; each test chamber has 30 stations in total, and the current, switch of all the testing zones can be set separately;
3) The system uses 3 channels of optical fiber for data acquisition, thus implements dynamic monitoring and recording on the variation of photoelectric output of the LED specimen at each station.
III. Testing software
1) The user may input some parameters, such as the stress current, stress temperature, test frequency, failure criterion, etc. to configure the measuring environment;
2) Real-time measurement of temperature characteristics of multi-channel LED;
3) Real-time measurement of forward current, forward voltage of multi-channel LED, and the current programmable settings of constant current power supply;
4) Temperature control setting of constant temperature oven, as well as real-time temperature measurement;
5) Realizes the automatic removal of current stress during failure of LED and stops the test of such device;
6) In case test is interrupted unexpectedly, the system can record the breakpoint automatically and allow the user to continue testing;
7) Convenient human-computer interface, with the functions of data export and statement printing & output;
8) With ability of mathematical statistics, it automatically analyzes the life trend of LED, and suggests the attenuation rate of optical power and the average life span (life expectancy) at such stress temperature;
9) With the ability of system fault self-diagnosis and repair;
