Human-Centric Lighting: Foundational Considerations and a Five-Step Design Process

Frontiers in Neurology, 2021
At its best, human-centric lighting considers the visual and non-visual effects of light in support of positive human outcomes. At its worst, it is a marketing phrase used to healthwash lighting products or lighting design solutions.

The Optical Effects of Capping Layers on the Performance of Transparent Organic Light-Emitting Diodes

IEEE Photonics Journal, 2012
In transparent organic light-emitting diodes (TOLEDs), the asymmetry in the optical paths causes difference between the bottom and top emitting lights, both in emissions and spectral distributions.

Controlling Light Harvesting with Light [PDF]

Journal of the American Chemical Society, 2016
When exposed to intense sunlight, all organisms performing oxygenic photosynthesis implement various photoprotective strategies to prevent potentially lethal photodamage. The rapidly responding photoprotective mechanisms, occurring in the light-harvesting pigment-protein antennae, take effect within tens of seconds, while the dramatic and potentially ...

Investigation of Efficiency and Droop Behavior Comparison for InGaN/GaN Super Wide-Well Light Emitting Diodes Grown on Different Substrates

IEEE Photonics Journal, 2014
In this work, efficiency droop of InGaN/GaN multiple-quantum-well LEDs with super wide well (WW) is discussed by comparing the external quantum efficiency (EQE) of GaN grown on sapphire and FS-GaN substrates.

The interaction of Light with Matter and Light with Light [PDF]

, 2020
This work consists of two fields of study involving the interaction of light with matter and light with light. The frst part explores the interaction of a superintense laser pulse with an ultrathin solid density foil. The radiation pressure exerted by the laser pulse can be so strong that, in principle, the whole foil is accelerated.

Dimming strategies for open office lighting : User experience and acceptance [PDF]

, 2018
Sensor-triggered control strategies can limit the energy consumption of lighting by considering the presence of users in the office and dimming lighting down when it is not needed. In multi-user offices, the application of occupancy-based dimming at room
