Projects
R&D systems architecture at Gavita
R&D systems architect on a contract basis.
NXTLED, a modular greenhouse toplight
One modular platform for a wide range of spectra and power levels, built on a single production line in the Netherlands.
RadBox, sterilisation for dental and medical use
Technical development of new sterilisation technology for the dental and medical markets.
Invisua, tunable LED lighting for retail
I founded Invisua and ran it for ten years. We made tunable LED lighting for shops, with our own LED modules, colour algorithms, optics and software.
Fortimo LED downlight platform
System architecture, technical strategy and test protocols for the Fortimo LED downlight platform.
Early high-power LEDs at Philips Lumileds
The first high-power LEDs, LED traffic light optics, illumination-grade white LEDs and projection light engines, including five years in San Jose.
Tools I built
ShadyTracer
A free, open-source path tracer that runs in the browser on WebGPU. It works with light in real units (lux, cd/m²), renders caustics through glass, and has an optics bench for LED and luminaire design.
Muxit
One server for every instrument on the lab bench, scriptable and with a visual interface. My own product, in private beta.
LED calibration system
Measures LED boards at a controlled temperature, regulated within 0.1 °C, while measuring current and voltage at the same time. Controlled wirelessly, so it fits into different lab setups.
Uniformity calculator
Helps with luminaire placement for even illumination. It takes fixture type, mounting height, beam angle and spacing, and calculates the light distribution and uniformity.
