Solid State Lighting [PDF]

Journal of Lightwave Technology, 2008
AbstractElectricity generation is the main source of energy-related greenhouse gas emissions and lighting uses one-fifth of its output. Solid-state lighting using light-emitting diodes (LEDs) is poised to reduce this value by at least 50%, so that lighting will then use less than one-tenth of all electricity generated.

The Optical Properties of InGaN/GaN Nanorods Fabricated on (-201) β-Ga₂O₃ Substrate for Vertical Light Emitting Diodes

Photonics, 2021
We fabricated InGaN/GaN nanorod light emitting diode (LED) on (-201) β-Ga2O3 substrate via the SiO2 nanosphere lithography and dry-etching techniques. The InGaN/GaN nanorod LED grown on β-Ga2O3 can effectively suppress quantum confined Stark effect (QCSE)

Size-Dependent Quantum Efficiency of Flip-Chip Light-Emitting Diodes at High Current Injection Conditions

Photonics, 2021
Versatile applications call for InGaN-based light-emitting diodes (LEDs) to operate at ultra-high current densities with high quantum efficiency. In this work, we investigated the size-dependent effects of the electrical and optical performance of LEDs ...

Wafer-Scale Semipolar Micro-Pyramid Lighting-Emitting Diode Array

Crystals, 2021
InGaN-based micro-structured light-emitting diodes (µLEDs) play a critical role in the field of full-color display. In this work, selected area growth (SAG) of a micro-pyramid LED array was performed on a 2-inch wafer-scale patterned SiO2 template ...

Solid‐state lighting [PDF]

Optik & Photonik, 2011
AbstractSolid‐state lighting is on the verge of replacing every lamp on earth, from the smallest signal lamp to the largest stadium‐scale flood lamp. We review the path that solid‐state lighting has taken: from its early years; to the pivotal period around 1999 when it began to be taken seriously; to the challenges it faced as it made continued ...
