SUNLUX called out PHIMECA to validate the proper operation of luminaires using thermal calculation: non-exceedance of a given temperature.

To do this, different steps were performed on the finite-element model:

  • Complete modelling of the LED luminaire with definition of conduction, convection, temperature, thermal transfer parameters.
  • Definition of the areas in contact playing a part in the conduction.
  • Definition of the areas that may radiate.
  • Fine modelling of the electronic components.
  • Realisation of a stationary and transitory thermal analysis.
  • Validation of the radiator design allowing the discharge of enough joules to comply with the thermal requirement.
  • Estimation of the mapping of the temperature fields.
