More than a century after the introduction of incandescent lighting and half a century after the introduction of fluorescent lighting, solid-state light sources are revolutionizing an increasing number of applications. Whereas the efficiency of conventional incandescent and fluorescent lights is limited by fundamental factors that cannot be overcome, the efficiency of solid-state sources is limited only by human creativity and imagination. The high efficiency of solid-state sources already… 

SOLID-STATE LIGHTING TECHNOLOGY PERSPECTIVE

Solid-State Lighting (SSL) uses inorganic light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs) to convert electricity into light for illumination. SSL has the potential for enormous

Energy efficient control of polychromatic solid state lighting using a sensor network

TLDR
This work developed both a spectrally tunable light source and an interactive lighting testbed to study the effects of systems that adjust in response to changing environmental lighting conditions and users' requirements of color and intensity.

Phosphor converters for laser driven light sources

Due to the “efficiency droop” effect of light-emitting diodes (LEDs) under high drive currents, laser diode (LD) driven light sources are considered to replace LED lighting for the next-generation

Smart design to resolve spectral overlapping of phosphor-in-glass for high-powered remote-type white light-emitting devices.

TLDR
The protocol for the current design of PiG possesses excellent thermal and chemical stability with high luminous efficiency and color purity is an attempt to make smarter solid state lighting for high-powered remote-type white light-emitting devices.

Importance of Eco-Friendly OLED Lighting

TLDR
The current state of the art, ongoing challenges and future perspectives of this research frontier to reduce the driving voltage, minimization of degradation issues, enhance their life time are illustrated.

Integration of non-Lambertian LED and reflective optical element as efficient street lamp.

TLDR
The imprinting technology and the reflective optical element were integrated to obtain a street lamp with high illumination efficiency and without glare effect, which has 40% enhancement in illumination intensity, the uniform illumination and the glare effect elimination.

Configuration, Function, and Operation of LED Lighting Systems

Light-emitting diodes (LEDs) have been exploited from laboratory plant researches to commercial cultivations in greenhouses or plant factories with artificial lighting (PFAL). Benefits of LEDs for

Signal processing for LED lighting systems : illumination rendering and sensing

TLDR
This thesis proves that the optimum uniformity can be achieved by setting the LED illumination levels to be identical, and finds that a weighted combination of Gaussian and raised-cosine functions as the basic illumination pattern yields the best uniformity among the considered basic illumination patterns with identical beam widths.

White light‐emitting diodes: History, progress, and future

About twenty years ago, in the autumn of 1996, the first white light‐emitting diodes (LEDs) were offered for sale. These then‐new devices ushered in a new era in lighting by displacing

Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor

TLDR
The results suggest that, in humans, a single photopigment may be primarily responsible for melatonin suppression, and its peak absorbance appears to be distinct from that of rod and cone cellphotopigments for vision.

Nanoheteroepitaxy: The Application of nanostructuring and substrate compliance to the heteroepitaxy of mismatched semiconductor materials

This article describes an approach to the heteroepitaxy of lattice mismatched semiconductors, that we call nanoheteroepitaxy. The theory developed here shows that the 3D stress relief mechanisms that

Phototransduction by Retinal Ganglion Cells That Set the Circadian Clock

TLDR
It is shown that retinal ganglion cells innervating the SCN are intrinsically photosensitive, and depolarized in response to light even when all synaptic input from rods and cones was blocked.

Melanopsin-Containing Retinal Ganglion Cells: Architecture, Projections, and Intrinsic Photosensitivity

TLDR
It is shown that melanopsin is present in cell bodies, dendrites, and proximal axonal segments of a subset of rat RGCs, most likely the visual pigment of phototransducing R GCs that set the circadian clock and initiate other non–image-forming visual functions.

TLDR
This work presents the first biological evidence for a potential link between constant light exposure and increased human breast oncogenesis involving MLT suppression and stimulation of tumor LA metabolism.
