Notes for Table 10:
1.Lumileds maintains a tolerance of ± 0.06V on forward voltage measurements.
2.Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs. See Figure 3.

Notes for Table 11:
1.Proper current derating must be observed to maintain junction temperature below the maximum. For more
information, consult the Luxeon Design Guide, available upon request.
2. Measured at leads, during lead soldering and slug attach, body temperature must not exceed 120ºC. Luxeon Emitters cannot
be soldered by general IR or Vapor phase reflow, nor by wave soldering. Lead soldering is limited to selective heating of the
leads, such as by hot bar reflow, fiber focussed IR, or hand soldering. The package back plane (slug) may not be attached by
soldering, but rather with a thermally conductive adhesive. Electrical insulation between the slug and the board is required.
Please consult Lumileds' Application Brief AB10 on
Luxeon Emitter Assembly Information
for further details on assembly
methods.
3.LEDs are not designed to be driven in reverse bias. Please consult Lumileds' Application Brief AB11 for further information.
