Segment: old buildings - old lighting fixtures. Purpose: energy savings and structural changes to artificial light system. Segment: Industrial new or recent (dimmable ballasts). Purpose: energy saving and high functionality of control Buildings which is essentially a constant light level. Purpose: absolute control over light combining daylight and artificial light dimming / control of both systems through an integrated approach

Several applications rely on light sources with a specific, predetermined emission spectrum. Such sources can be made by assembling monochromatic LEDs. However, the widely differing efficiency of monochromatic LEDs makes such a solution complex, expensive and inefficient. Using a blue LED as the sole primary light source in combination with Quantum Dot (QD) technology can address these issues, however this approach faces regulations on the ...

The study of the impact of the illumination spectrum on object color appearance–referred to as color rendition–and on lighting color quality has been an active research topic for several decades. Studies have shown that the worldwide standard, the CIE color rendering index (CRI), fails to accurately predict visual color rendition properties of many light sources, especially those with narrowband spectral features. In 2015, the Illuminating ...

The research project takes up two main aims: (1) to explore the theoretical underpinnings of, and relations between, the necessity and proportionality conditions of just war theory, and (2) to formulate necessity and proportionality in formal logical terms, so that they can be more easily engaged with, and so that their underlying structure can be made more clear.

Current lighting control systems adapt the emitted light intensity levels of multiple luminaires, by using a network that incorporates light- and motion sensors. A more recent evolution is the dynamic control of the color temperature to influence how people feel and perform. However, further innovation on the level of the lighting luminaires and the accompanying sensor technology is needed, to realize the long-standing promise of providing ...

The global objective of this project is to accelerate the transition from lighted crops to full LED lighting systems. LED FR wants to stimulate the transition process through a two-pronged approach: via an interactive light platform, growers develop the necessary competences to make the right investment decision and to be able to implement the light strategies developed (by the project).Research into the control light far red is the lever to ...

Remote phosphor plates are increasingly used in LED modules to obtain auniform white light distribution by converting part of the blue LED light into light with a longer wavelength. Remote phosphor plates also havethe potential to improve the system performance of display backlights if luminescent materials with a narrow emission band (e.g. quantum dots) are considered.

The goal of this research is to find new concepts and ...
