Hi

I would like to know the lifetime of  LED (RGB) of Lightcrfater.

If you have any expected information under some condition.

(e.g. x x lm / x x degree / etc )

That will be helpful for me to understand

Best  Regards

Tommy

    Hi Tommy,


    Below are the part number for Lightcrafter LEDs,

    • Red OSRAM OSTAR Compact LED - LE A Q9WN
    • Green OSRAM OSTAR Compact LED - L CG H9RN
    • Blue OSRAM OSTAR Compact LED - LE B Q9WN

    The maximum operating temperature range is -40 to 100 deg C at a maximum forward current of 1A.

    As mentioned in the user's guide, the passively cooled Lightcrafter devices (no extra heat sinks or fans) have a thermal limit resulting in LED currents under 633 mA and actively cooled systems (extra heat sink and fan) have a thermal limit resulting in LED currents under 1.5 A.

    You might have to contact OSRAM for life expectancy of these LED's.

    Regards,

    Divya
