Case Temperature Measurement Point
A case temperature measurement point location is included on the top surface of the Bridgelux LED
Arrays. The location of this measurement point is indicated in the mechanical dimensions section of this
data sheet.
The purpose of this measurement point is to allow the user access to a measurement point closely linked
to the true case temperature on the back surface of the LED Array. Once the LED Array is installed, it is
challenging to measure the back surface of the array, or true case temperature. Measuring the top
surface of the product can lead to inaccurate results due to the poor thermal conductivity of the top layers
of the array such as the solder mask and other materials.
Bridgelux has provided the case temperature measurement location in a manner which closely ties it to
the true case temperature of the LED Array under steady state operation. Deviations between thermal
measurements taken at the point indicated and the back of the LED Array differ by less than 1° C,
providing a robust method to testing thermal operation once the product is installed.
