Case Study: Philips Lighting achieves faster, optimized high-pressure gas discharge lamp design with ANSYS Multiphysics

Philips Lighting - Customer Case Study

Philips Lighting, the lighting division of Royal Philips Electronics, faced the challenge of designing thermally and mechanically robust high‑pressure Ceramic Discharge Metal‑halide (CDM) lamps that meet specified lifetimes. Accurately predicting the nonlinear gas discharge, lamp wall temperatures and mechanical stresses was critical, so Philips Lighting turned to ANSYS and used ANSYS Multiphysics to address these multi‑physics design requirements.

Using ANSYS Multiphysics, Philips implemented a single coupled model combining fluid, electric, thermal and mechanical fields (treating the gas discharge as a conductive fluid) to capture heat generation, gas flow, wall temperatures and ceramic stresses. ANSYS enabled Philips to model the nonlinear discharge in one run, run several tests in a single day, speed up new lamp development, optimize designs and gain a thorough early‑stage understanding of performance to better meet lifetime targets.
