Forward voltage temperature coefficient at 1.75A. Contact Luminus for value at other drive conditions.
Listed drive conditions are typical for common applications. PhlatLight SST-50-W devices can be driven at currents ranging from
<1A to 5A and at duty cycles ranging from <1% to 100%. Drive current and duty cycle should be adjusted as necessary to maintain
the junction temperature desired to meet application lifetime requirements.
Unless otherwise noted, values listed are typical.
Luminus PhlatLight SST-50-W LEDs are designed for operation to an absolute maximum forward drive current 5A. Product life-
time data is specified at recommended forward drive currents. Sustained operation at absolute maximum currents will result in
a reduction of device lifetime compared to recommended forward drive currents. Actual device lifetimes will also depend on
junction temperature. Refer to APN-001521: Reliability Application Note for SST-50-W for further information. In pulsed opera-
tion, rise time from 10-90% of forward current should be larger than 0.5 microseconds.
Lifetime dependent on LED junction temperature . Thermal calculations based on input power and thermal management system
should be performed to ensure Tj is maintained below Tjmax rating or life will be reduced. Refer to APN-001521 for further
information.
CIE measurement uncertainty for white devices is estimated to be +/- 0.01.
Special design considerations must be observed for operation under 1A. Please contact Luminus for further information.
Caution must be taken not to stare at the light emitted from these LEDs. Under special circumstances, the high intensity could
damage the eye.
