PORTLAND, Ore. — More efficient light-emitting diodes (LEDs) are increasingly being used for solid-state lighting, and researchers say technology advances could expand their use. Researchers at ...

Smartphones, laptops, and lighting applications rely on light-emitting diodes (LEDs) to shine bright. But the brighter these LED technologies shine, the more inefficient they become, releasing more ...

Recyclers must swiftly adapt to prepare for the significant surge in LED lighting products as the global shift toward energy-efficient LED lighting is projected to grow at a compound annual rate of 11 ...

China-based makers of LED materials, including aluminum substrates, copper foil and plastic materials, have hiked quotes by 30-40%, sending China-based LED chip makers raising prices by about 10%.

A Korean research team has developed a deep-ultraviolet (DUV) LED with an entirely new material. The DUV LED refers to a semiconductor light source designed to emit ultraviolet (UV) light with a short ...

Seeking to reduce the cost of solid-state lighting and related applications, LED manufacturers are taking a page from the IC industry: They are looking at larger wafer sizes and new materials in the ...

Researchers in Tokyo have created a spinel sulphide LED material that can can be tuned to emit light at wavelengths between orange and blue, and has photovoltaic properties. Spinel is a type of cubic ...

Engineers at Berkeley Lab have come up with a simple way to increase an LED’s efficiencies. Smartphones, laptops and lighting applications rely on LEDs to shine bright. But until now, the brighter ...
