T
Duty Cycle used to specify device ratings under Pulsed operation. LED devices can operate at duty cycles ranging from 1% to 100%. At higher duty cycles, drive
current should be adjusted to maintain the junction temperature at desired levels to meet the application lifetime requirements.

In pulsed operation, rise time from 10 to 90% of forward current should be larger than 0.5 microseconds

Note 1:
Note 2:
Product performance and lifetime data is specified at recommended forward drive currents. Sustained operation at or near absolute minimum currents may
result in a reduction of device performance and device lifetime compared to recommended forward currents.
Maximum forward drive current conditions for continuous operation are 11.9 A, CW (2.2 A/mm2 ), and 16.2 A, f>240 Hz, duty cycle <70% ( 3.0 A/mm2 )ꢀ
Sustained operation above maximum currents is not recommended and will result in a reduction of device lifetime compared to specified maximum forward
drive currents. Device lifetimes will depend on junction temperature. (See Reliability Application Note, APN-001444 for product lifetimes as function of
junction temperature.) Please refer to lifetime de-rating curves (available from Luminus ) for further information.
Note 3:
Note 4:
In pulsed operation, rise time from 10 to 90% of forward current should be larger than 0.5 microseconds.
Sustained operation at or above Absolute Maximum Operating Junction Temperature (Tjmax) will result in reduced device life time. Device lifetimes will depend
on junction temperature. (See Reliability Application Note, APN-001444 for product lifetimes as function of junction temperature.) Please refer to lifetime
de-rating curves (available from Luminus ) for further information.
