BulbAmerica, America’s largest online and wholesale retailer of light bulbs and lighting fixtures, has announced the launch of an LED support system. LEDs are all set to make more efficient street lights with less light pollution and this technology that now provides the back-light for many flat panel TVs will also replace fluorescent tubes in commercial applications. Slow in gaining traction, though this technology has been around for more than 100 years, it found commercial applications only in the late 1960s as costs fell. While Japan is the largest market for LED...

Earlier in May, Panasonic Corp announced that it has developed a white OLED with the world's highest luminous efficiency of 114 lm/W. Improvements in the efficiency of this OLED device were due to  the company's focus on optimizing light extraction technology for an all-phosphorescent white OLED.  As a reminder, Panasonic Idemitsu OLED Lighting, a joint venture of Panasonic and Idemitsu, began volume production of OLED lighting panels in October 2012.  The partnership was established back in 2011,with an initial investment of $182 M...

Serial-drive Pixel Light implementations can lead to streamlined, modular control solutions for AFS systems, leading to greatly enhanced night-time driving safety. Only 25% of travel by car takes place in the hours of darkness, yet over 40% of all major accidents (with fatalities or serious injuries ensuing) occur during this time, according to figures published by the U.S. National Highway Traffic Safety Administration (NHTSA) and the European Commission (EC). This has spurred on automobile manufacturers to find possible solutions, culminating in the implementation...

VTT Technical Research Centre of Finland has developed a dimmable LED street light that consumes significantly less energy than current lighting systems, while improving the lighting characteristics. The street lights were tested in Helsinki with user experiences collected. Traditional street lights work on full power when turned on, and the amount of light is not usually adjusted. The new LED street lights developed by VTT adapt to the ambient conditions with the help of sensors and wireless control, allowing them to be dimmed on the basis of natural light, environment...

LEDs are extremely efficient, and when it comes to single colors such as red or green commonly used in traffic lights or toys, they can’t be beat. But those aren’t the colors we want to light up our homes and offices. Our eyes prefer the warm, white light produced by the sun, and when it’s not available, we’ll take the similar glow produced by CFLs and incandescent bulbs. Soon, however, those traditional options won’t be available, and good riddance. They suck up way more energy than should be necessary to light a room. Scientists have been worki...

Texas Instruments Incorporated (TI) introduced the next-generation AEC-Q100 qualified automotive LED drivers, feature-packed with the industry’s highest voltage rating, thermal shutdown protection and optimized electromagnetic compatibility (EMC) performance.

This “pinkhouse” at Caliber Biotherapeutics in Texas, grows 2.2 million plants under the glow of blue and red LEDs. The practice of vertical farming could potentially undergo a transformation that will make urban food centres more productive. Although many people believe vertical farming is unpractical, it is becoming increasingly popular as agricultural space becomes scarcer and people desire food produced closer to home. One major problem that arises with vertical farming practice is that of lighting. By stacking plants on top of each other, it creates sha...

Panasonic Corporation has developed a white OLED with the world's highest luminous efficiency*1 of 114 lm/W (light-emitting area of 1 cm²). In addition, a luminous efficiency of 110 lm/W has also been achieved with a device with a larger emitting area of 25 cm². In order to achieve such a level of high efficiency with the OLED, the company focused on "light extraction technology" and the "all phosphorescent white OLED technology" (technology for the multilayering of the organic emitting layer). OLEDs are capable of emitting any co...

Reportedly, Apple's iPad 5 will be up to 33% lighter than its predecessor. The tablet is rumoured to be going into production in July ahead of a September launch, with the Cupertino firm shedding a third of the iPad 4's weight for its latest model. The next generation iPad will keep its 2048 x 1536 Retina display by using a thinner 0.2mm piece of glass. Just one LED light bar will apparently be used for backlighting - the iPad 4 currently uses a 0.25mm glass substrate and two LED light bars. Supply chain sources in Taiwan told DigiTimes that the bezel ...

As June is dawning near, LEDinside is ready to hold a grand and perfect LEDforum 2013 Guangzhou at the Chinese Export Commodities Fair Pazhou Complex, Area B, Room # 8.   LED industry has undergone big changes. Based on the potential market demands, many companies have mushroomed all over the world in recent years. However, an oversupply comes after the large capacity expansion.

According to new research by Wageningen UR Greenhouse Horticulture in collaboration with Philips, exposing tomatoes to extra light from LED lamps during the growing process boosts the fruit’s nutritional value by nearly doubling the amount of vitamin C. The partnership will be continued in a joint facility for research into the application of LED lamps in horticulture (IDC LED) that will open May 16 in Bleiswijk. Scientists at Wageningen UR studied several tomato varieties and various intensities of light. They used special LED modules that were sus...

Recently, a new research has claimed that the so-called ecofriendly LED lights may cause permanent damage to your eyes. The study found that exposure to LED lights can cause irreparable harm to the retina of the human eye. According to Think-Spain.com, once the retina cells are destroyed by prolonged and continuous exposure to LED rays, they cannot be replaced and will not regrow. Researchers said this is caused by the high levels of radiation in the 'blue band' , and is likely to become a global epidemic in the medium term given that computer, mobiles and TV s...
