Calibrated climate-based lighting simulation models of buildings have the capacity to perform an essential role in postoccupancy evaluations, such as annual frequency assessments of daylighting quality and visual discomfort. However, in most postoccupancy ...
A high-power LED-based illumination system has been developed as a replacement for the mercury arc lamps used in mask-aligner lithography. LEDs are arranged in a grid array and placed in the entrance aperture of individual reflectors. Those reflectors decr ...
In a control unit (8) for a lighting control system, wherein the control unit (8) is configured to calculate output values based on input values and the output values include control commands for a lighting installation (4, 6, 7.1, 7.2), the input values i ...

The purpose of this report is to detail the findings of a long-term evaluation study on the impact of installing electrochromic glazing in two different buildings owned by Audemars Piguet. The two locations under investigation are the APRP ateliers in Le L ...
Mask-aligner photolithography is a technology used to replicate patterns from a mask to a photosensitive substrate. It is widely used in the fabrication of MEMS and micro-optical components, and for other applications with dimensions in the micrometer rang ...
A smart luminaire able to change the direction of its light beam is installed in an office environment and compared to the available LEDs fixtures. Standard lighting measures are performed and a controlled user experiment is conducted, involving 22 subject ...
