All ratings are based on test conditions of Tj=25C, 20 millisecond pulse. See Thermal Resistance section for Tj definition.
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.
Forward voltage temperature coefficient at current density of 0.35 A/mm
tions.
Luminus PhlatLight SST-50-W LEDs are designed for operation to an absolute maximum forward drive current density of 1.0 A/
mm2. Product lifetime data is specified at recommended forward drive currents. Sustained operation at absolute maximum cur-
rents 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 the lifetime derating curves for further information. In pulsed operation, rise
timefrom 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 may be reduced. Refer to lifetime plots on pg 6 and
lifetime and reliability application note 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.
