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.

Researchers of the UK-based University of Exeter have found that LED street lighting can be customised to reduce its impacts on the environment. The study found that the number of species affected by the LED lights was significantly reduced when the LED lights were dimmed by 50%, and switched off...

Lighting Science, a noted brand in next-generation LED lighting solutions, announces the comprehensive results from a study, “The effects of spectral tuning of evening ambient light on melatonin suppression, alertness and sleep”, published today in the medical journal Physiology and Behavior.

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.

Through a new project called DarkLight, researchers have developed and demonstrated for the first-time, how visible light can be used to transmit data even when the light appears dark or off. DarkLight provides a new communication primitive similar to infrared communication, however, it exploits the LED lights already around us...

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.

For the first time, researchers have created light-emitting diodes (LEDs) on lightweight flexible metal foil. Engineers at Ohio State University are developing the foil based LEDs for portable ultraviolet (UV) lights that soldiers and others can use to purify drinking water and sterilize medical equipment.

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,...

Researchers from Skolkovo Institute of Science and Technology, Russia along with scientist from the UK and Taiwan have come up with a new photonic white light-emitting diode (LED) structure with unparalleled efficiency parameters. This new technology has paved way for ultra-thin and reasonable LEDs.

Osram and German Skiing Association (DSV) are developing LED eyewear, particularly for flight passengers. The eyewear will give the users a ‘light shower’ as it has high luminous flux, and utlilizes circadian rhythms, and will help them beat jet lag quicker by keeping the aware and awake. These glasses will...
