Royal-Blue (447.5nm) LUXEON Rebel ES LED on a SinkPAD-II 40mm Round 7-Up Serial Base - 7210 mW @ 700mA

Royal-Blue (447.5nm) LUXEON Rebel ES LED on a SinkPAD-II 40mm Round 7-Up Serial Base - 7210 mW @ 700mA
The SP-02-V4 LED assembly features 7 serially connected LXML-PR02-A900 Royal-Blue LUXEON Rebel ES LEDs soldered to a SinkPAD-II 40mm round 7-Up 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.

Additional non-stocked Royal-Blue SinkPAD-II round 7-Up assemblies can be ordered here.

The SP-02-V4 has been specifically designed to accommodate the Polymer and Khatod 7 Cell Cluster series of optics, including:

The LEDs can be powered singly or in series with the addition of 0 ohm resistors or solder dots. A Vishay NTC 10K Thermistor (NTHS0805N02N1002J) is mounted to the board to monitor temperature and can be used for foldback temperature control. For more information about using the thermistor, please review our SP-02 Onboard Thermistor Temperature Measurement application note.

Want to power this LED assembly from a voltage as low as 10VDC? Then check out the FlexBlock LED driver. A single driver can power all 7 of these LEDs connected in series with any voltage from 10V to 18V*.

Need a mixture of different color LEDs mounted to this board? A custom version of this assembly is also available.

* The maximum input voltage to the driver must be less than the total forward voltage of all series connected LEDs.

  1. As royal-blue LEDs are close to the UV range, LEDs are rated by radiometric power (mW) instead of lumens.
  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 the recommended operating current.
  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.

Thermal Management

SP-02-V4 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 LXML-PR02-A900 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-02-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 9 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-02-V4 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, Arctic Silver thermal adhesive or screws with thermal grease. 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. If you are using screws, be careful not to warp or distort the assembly by over tightening the screws.
