A cozier LED bulb may be available in the near future, thanks to German researchers. Scientists from Dresden University of Technology in Germany are striving to create energy efficient organic LED (OLED) lights that could rival incandescent bulbs in white-light color quality. One of the major complaints consumers report when dealing with LED light bulbs is that they still do not emit that same pleasant, warm color of light that makes incandescent bulbs so popular, despite their energy-guzzling qualities. According to TruthDive, “OLEDs consist of many layers of organic materials with different electrical properties. Excited electrons move through the materials and when the electrons are reunited with positive “holes,” they emit electromagnetic radiation in the form of visible light.” Combining these emitter layers in four separate colors (blue, green, yellow and red) and adjusting the height of the layers makes it possible for the researchers to create light color and quality that was previously unachievable in LED lighting.  The results of this endeavor were published in AIP’s Journal of Applied Physics, which found that the final LED light fixtures cast a color of light that was very near the standard measure of white light reached by some incandescent bulbs. “The OLED also has high colour stability, meaning the light can be dimmed without noticeably altering its quality,” according to TruthDive.

It’s a well-known truth that we humans love glowing, sparkling things. For proof of that fact, one needs only to note the growing number and popularity of international lights festivals. A few weeks ago I blogged about the Harbin Ice Festival in China, which displays amazing frozen artworks and sculptures illuminated by flexible LED lights. Their beauty was enough to make me want to drop everything and head on over to the other side of the globe to see it for myself.

And now I’m having that same feeling about the 2012 Light Festival in Ghent, Belgium. Not only am I certain that I would enjoy a cornucopia of Belgium’s delicious chocolate and beer, I’m quite convinced I would also be blown away by the LED light installations at this festival—30 of them, to be exact. One in particular seems exceptionally intriguing: a 91-foot tall cathedral made with 55,000 color changing LED lights and constructed by Luminarie De Cagna, an Italian lighting company. The installation pays homage to Luminarie De Cagna’s almost 100 year tradition of illuminating buildings and squares on festive occasions. It began in the 1930s with candles and oil lamps, and continues to this day with waterproof LED lights.

And thanks to efficient LED light technology, the cathedral only uses 20 kilowatts of energy per hour, but can display a whole range of patterns and colors, by employing an RGB controller.

Have any of you ever visited a light festival like this one? We’d love to hear your stories!

About SemiLEDs
SemiLEDs Corporation develops and manufactures LED chips and LEDponents primarily for general lighting applications, including street lights andmercial, industrial and residential lighting. SemiLEDs sells blue, green and ultraviolet (UV) LED chips under the MvpLED brand.

Everlight Electronics Co., Ltd., a leading player in the global LED industry, announces a series of Low/Mid Power LEDs* especially suited for use in solid state lighting. The new Low/Mid Power LED family has the ability to provide customers a total solution for lighting applications.

General Lighting is an interesting and broad market segment. For any individual segment of lighting there are multiple categories and sub categories with different requirements and functionalities. Outdoor lighting epasses street lighting, tunnel lighting, parking lot lighting,
landscape lighting, as well as a slew of other applications. Indoor Lighting epasses replacement bulbs, down lights, light bars, etc. As an example, replacement bulbs are further categorized down to directional bulbs, decorative bulbs, and omnidirectional bulbs. Furthermore, directional bulbs are sub categorized into MR16, PAR, AR111, etc.

With a bit of application based marketing, “The Right LED” can be paired with the appropriate applications to provide the best performance and quality. Everlight's recent announcement of its Low/Mid Power LED series is directed towards light bar replacement and omnidirectional bulb applications. This series consists of 0,06W, 0,2W, 0,4W, and 0,5W products with efficiencies of >100lm/W. These LEDs are of different form factors; 3020 and 3528 (0.06W), 5050 (0.2W), and 5630 (0.4W and 0.5W) package sizes.

The 3020 and 3528 (0.06W) packages are ideal for light bar applications. Many of these small packages can be densely packed onto a linear heat sink to provide the required light uniformity of linear solutions. As a result, a linear LED light bar can emulate the appearance of traditional fluorescent tubes. In addition, because these are small, low power LEDs, the minimal thermal dissipation of linear fixtures is sufficient in maintaining a low substrate temperature as well as a low junction temperature within the LED, resulting in better performance and lifetime. To increase the advantage of using low power LEDs and improve overall light quality in the fixtures, Everlight can offer 200mcd/bin for intensity uniformity and 0.1V/bin for more consistent electrical design.

The most recent market trend and direction for the general lighting market is towards cost conscious, consumer price acceptable replacement A-bulbs. It is predicted that 257 million A-bulbs will be sold worldwide in 2013. With current price and performance pressures, the Mid Power 5630 (0.4W and 0.5W) package is aggressively surpassing traditional COB and high power LED light sources as the preferred package type for A-bulb applications. 5630 packages have superb lm/$. This is derived from thebined resources of the backlighting and the general lighting market. This shared capacity results in stable quality andmercialpetitiveness over other types of LEDs. In addition, the balance of lumens output, power consumption, and package size allow the 5630 to optimally spread light and heat by spatially distributing the LEDs uniformly in the dimensional confines of an A-bulb.

All Everlight Low/Mid Power LEDs follow ANSI binning, have a wide range of CRI values, and are undergoing LM80 testing. The flexibility of Everlight Low/Mid power LED in packaging, binning and chip selection gives engineers more options in creating unique lighting fixtures with acceptable prices.

Everlight is fostering closer working relationships between our R&D, Sales and Marketing teams to meet and exceed our customer's expectations in both product offering and technology. Everlight's Low/Mid Power LED Series are expected to satisfy the fastest-growing global LED lighting market.
