The standard high-brightness LED merely converts about 45% of energy, while the rest 55% is given out as mere heat. Now, it is important to quickly remove heat from the LED in order to prevent overheating of the LEDs. This is known as thermal management that has been challenging the manufacturers...

For the first time, an international research group has uncovered the core mechanism that limits indium (In) incorporation into indium gallium nitride ((In, Ga) N) thin films – the key material for blue light emitting diodes (LEDs).

Researchers from the University of Twente have discovered a unique numerical light transport tool that can help the lighting industry design more efficient white LEDs, as it provides a fast yet accurate determination of key transport parameters, and also introduces predictive power into the design process of white LEDs.

A team of researchers at the University of Edinburgh, UK, did a year long research to find out if Li-Fi could be detrimental to the energy-efficiency of LEDs used as lighting sources. The research has been funded by the Engineering and Physical Sciences Research Council (EPSRC).

Researchers of the Korea Institute of Machinery and Materials (KIMM) have developed a new technology to facilitate the mass transfer process of micro LED manufacturing.

The University of Guelph in Controlled Environment Systems Research Facility (CESRF) has been investigating controlled-environment plant production and how to grow plants in space for food, oxygen, fresh water and carbon dioxide—human life supports.

Night shifts are actually bad for our health as it is linked to chronic disorders like cardiovascular disease and cancer. When our sleep is disrupted it definitely affects our health as it is set by light. So scientists are trying to find out if smart LED lighting can help solve...

Plessey, a leading developer of award-winning LED technologies and manufacturer of solid-state lighting products, announces the results from a trial of its LED grow lights combined with existing high-pressure sodium (HPS) lighting in a hybrid installation with a leading tomato grower in the Netherlands.

Demand for energy efficient LED bulbs is picking up. However, there have been complaints that energy efficient light bulbs cause headaches. According to a professor at England’s University of Essex, LED lights flicker around 100 times per second, which is known to cause headaches and or leading to pain or...

Researchers from KU Leuven (Belgium), the University of Strasbourg, and CNRS have discovered a new phosphor that can pave way for efficient and cheap fluorescent and LED lighting, The researchers used highly luminescent clusters of silver atoms and the porous structure of minerals called zeolites.

Although LEDs have now become popular and their applications are increasing, white LEDs still need some improvement. Moreover, manufacturing white LEDs is quite complicated. Researchers at University of Erlangen (FAU) have developed a new and unique method of manufacturing LEDs. They have made LEDs partly with fluorescent proteins.

For the first time in the world, Kim Dae-hyeong, a researcher at the Institute for Basic Science (IBS), has developed a flexible display cell that uses quantum dot and produces more vivid colors. It is called Quantum Dot Light Emitting Diode (QLED). QLED is only 2.6-micrometer thick, and is about...

MIT researchers headed by Sumeet Kumar, have developed a new way to map streetlights. This innovative method takes a cue from Google’s fleet of street view cars. The researchers have come up with a set of sensors that can be mounted on top of cars that regularly drive around the...

Illinois University researchers have come up with a new technique, which involves gallium nitride (GaN) cubic crystals grown on a silicon substrate. These crystals can help in generating powerful green light for superior solid-state lighting that influences industry-standard semiconductor expansion method.

In this technological era, there are Wi-Fi-powered lights that can be switched on and off on your command and more interestingly, it tracks your movements and then drops a message on your email or Facebook. However, you need to know that one of the first IoT gadgets to get hacked...

New research focusing on quantum well thickness in cyan green LEDs pave way for a better understanding of improving drop behaviour and bandwidth of LEDs.

Till date, LED lamps and luminaires have faced flicker issues due to several reasons, and AC/DC drivers is one of them. AC-LED technology may prove more cost effective and reliable compared to AC/DC designs. Now, with driverless AC-LED lighting solution, it is easy to make a product economical.

COB technology has helped in removing the deficiencies of SMD technology, paving way for better, cheaper and brighter LED lighting. This new technology for LED packaging has a number of benefits like homogenous luminosity, ability to spread light across a large area, energy efficiency, compactness and effective thermal management.

Tunable-white LED lighting has been the latest trend in commercial lighting. A simple yet attractive way to make a workplace look more attractive is to redesign the office environment with tunable-white LED lighting. Besides offices, tunable-white LED lighting is also becoming increasingly popular in healthcare and education applications.

Researchers in the US has proved that light produced by LEDs can speed up plant growth, and can also improve the taste of fruits and vegetables. The researchers are also proving that LED light can treat disease in plants. This discovery can cut down on the usage of expensive and,...
