Circuit Schematic
Notes:
1. φ_v is the total steady state flux of
the assembly after thermal
stabilization.
2. The thermal resistance assumed
is R_{th-junction-ambient}=12.9°C/W, which
represents the thermal resistance
of the LED assembly when the
substrate is potted in epoxy resin.
To determine junction
temperature, multiply R_th by power
consumption and add to ambient
temperature.
3. No LED emits more than 2 times
the flux of any other LED within
the same assembly.
Notes:
1. The dominant wavelength is
derived from the CIE Chromaticity
Diagram and represents the
perceived color of the signal.
2. The dominant wavelength does not
vary between emitters by more
than 8nm within the same
assembly.
