Review this item Review this item
The SP-08-D2 LED assembly features 4 LXM3-PD01 Deep Red LUXEON Rebel LEDs soldered to a SinkPAD-II 23mm Round base.

The SinkPAD-II uses second generation technology to minimize thermal resistance by eliminating the dielectric layer so that the LED thermal pad is soldered directly to the aluminium base. This ensures the lowest possible LED junction temperature, resulting in increased LED life, lumens output and overall reliability.
Part Number : SP-08-D2

  1. Values for LEDs from flux bin D.
  2. Values based on 350mA and a Thermal Pad temperature of 25C.
  3. Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
  4. This is the maximum operating current that we recommend for this LED. Higher drive currents may be possible, but will require careful design of a suitable cooling system.
  5. At 350mA.
  6. Typical thermal resistance from the LED Junction to the bottom of the board.
  7. This is the value we recommend you use for determining driver input voltage.
  8. As deep red LEDs are close to the IR range, LEDs are rated by radiometric power (mW) instead of lumens.

Thermal Management

SP-08-D2 LED assemblies must be operated to ensure that the junction temperature of the LEDs are kept well below the maximum ratings as specified in the LXM3-PD01 datasheet. A heat sink must always be used when operating this assembly. The size of the heat sink will depend on the ambient temperature and the current that is used to power the LEDs. Bench testing that we have conducted with a SP-08-N4 assembly powered at 700mA in an open air environment and an ambient temperature of 25°C has indicated that a heat sink with a thermal rating of 10 C°/W or lower should be adequate. However, you will need to perform your own testing and analysis to determine if this size of heat sink will be suitable for your application.

The SP-08-D2 must be fastened to the heat sink using a thermal interface material such as our pre-cut Bond-Ply 100 pressure sensitive, double sided thermal tape or Arctic Silver thermal adhesive. Before fastening the assembly to the heat sink, ensure that the two mating surfaces are perfectly flat and clean in order to maximize heat transfer to the the sink. This assembly is not designed to be fastened with screws.
