Thermal Management
A suitable finned heatsink or other cooling method must always be used with the SR-02-D2040 LED module to ensure that the junction temperature of the LEDs is kept well below the maximum rating specified in the Lumileds datasheet. The size of the heatsink will depend on the ambient temperature and the current used to power the LEDs.
Bench testing that we have conducted with SR-02 CoolBase modules 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 must perform your own testing and analysis to determine if the heatsink you select is suitable for your application.
We recommend that the module be mounted to an aluminum or copper finned heatsink exposed to open air for optimal cooling. The module can be mounted to the heat sink in one of two ways:
- 40mm round pressure-sensitive, thermally conductive tape (Recommended)
- Arctic Silver thermally conductive adhesive
Before fastening the module to the heat sink, ensure that the two mating surfaces are perfectly flat and clean to maximize heat transfer to the heatsink. Mechanical fasteners are not recommended for this module.
A Vishay NTC 10K Thermistor (NTHS0805N02N1002J Thermistor datasheet) 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 SR-02 Onboard thermistor temperature measurement information in the SR-02 module datasheet.
The bottom of the LED module is electrically neutral, so it is unnecessary to electrically isolate the base from the cooling surface.
Connection
This LED module can be powered in parallel or series by adding 0-ohm resistors or solder dots.
Want to power this module from a voltage as low as 10VDC? Then check out the FlexBlock LED drivers. A single driver can power all 7 of these LEDs connected in series with any input voltage from 10V to 18V. Note that the maximum input voltage to the driver must be less than the total forward voltage of all series-connected LEDs.
Mixed Color LEDs
Need different color LEDs mounted to a single 7-Up module? A color-mixing version is available.
Stock
We usually keep a small number of this part in stock. However, we can produce virtually any quantity you require on demand. Please get in touch with us for lead times for orders above 1,000 pieces.
LED Binning
Order quantities of less than 140 pieces are produced from unbinned stock (cut strips). We can supply binned LED modules (built from full reels)) If you order in 140+ quantities, please contact us for binning details.
You can learn more about LED binning here.

High-power LEDs include a primary optic for protection and light optimization. However, a secondary optic is often essential for better focus and light distribution.
All the optics except the Polymer 15 mm optic are 100% compatible with the SR-02-D2040 LED module. Polymer 15 mm optics cannot be used if you select the connector option.
Note: The optics listed here may not be ideal for ultraviolet or infrared LEDs. You will need to test the optic for your specific application.
