lumen maintenance Projections
Cree now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED
lumen maintenance. For information on the specifc LM-80 data sets available for this LED, refer to the public LM-80
results document at www.cree.com/xlamp_app_notes/LM80_results.
Please consult the XLamp Long-Term Lumen Maintenance application note at www.cree.com/xlamp_app_notes/lumen_
maintenance for more details on Cree’s lumen maintenance testing and forecasting. Please read the XLamp Thermal
Management application note at www.cree.com/xlamp_app_notes/thermal_management for details on how thermal
design, ambient temperature, and drive current affect the LeD junction temperature.
moisture sensitivity
XLamp MX-3S LeDs are shipped in sealed, moisture-barrier
bags (MBB) designed for long shelf life. If XLamp MX-3S LEDs
are exposed to moist environments after opening the MBB
packaging but before soldering, damage to the LeD may occur
during the soldering operation. The derating table at right
defnes the maximum exposure time (in days) for an XLamp
MX-3S LeD in the listed humidity and temperature conditions.
LEDs with exposure time longer than the time specifed below must be baked according to the baking conditions listed
below.
Cree recommends keeping XLamp LeDs in their sealed moisture-barrier packaging until immediately prior to use. Cree
also recommends returning any unused LeDs to the resealable moisture-barrier bag and closing the bag immediately
after use.
baking conditions
It is not necessary to bake all XLamp MX-3S LEDs. Only the LEDs that meet all of the following criteria must be baked:
1.
LeDs that have been removed from the original MBB packaging.
2.
LEDs that have been exposed to a humid environment longer than listed in the Moisture Sensitivity section above.
3.
LeDs that have not been soldered.
LEDs should be baked at 70
oC for 24 hours. LEDs may be baked on the original reels. Remove LEDs from MBB packaging
before baking. Do not bake parts at temperatures higher than 70
oC. This baking operation resets the exposure time as
defned in the Moisture Sensitivity section above.
