South Korean LED manufacturing Giant Seoul Semiconductor and Japan-based Toshiba Materials held a press conference introducing SunLike, a new LED technology supported by Toshiba’s TRI-R phosphor solution, in Frankfurt, Germany. The SunLike LEDs with TRI-R phosphor technology simulate sun in terms of emission spectrum, eliminating excessive blue light and appearing to be more friendly to human eyes and circadian rhythm.

SemiLEDs Corporation (NASDAQ: LEDS), a global provider of vertical LED technology solutions, announced sampling and volume availability of its Phosphor Converted, or PC LED chip series. The series launches with PC Amber, PC Green and PC Red LED chips in a 40mil (1mm x 1mm) chip size. SemiLEDs PC LEDs utilize SemiLEDs’ proprietary ReadyWhiteTM phosphor technology to minimize blue pass through, thus achieving higher luminous flux, efficiency, and lumen maintenance over time and temperature compared to monochromatic LED chips.

The judge’s final verdict will probably be based on Michigan Federal jury findings that two Nichia patents were invalid in the case against Everlight, said former Industrial Technology Research Institute (ITRI) researcher Jerry Yu.

To satisfy consumer demand for fresh, affordable produce and other horticultural products throughout the year, growers are increasingly turning to indoor growing operations. Growers are using indoor hydroponics and aquaponics systems that are more efficient in producing year around yields without the threat of droughts, diseases, or nutrient deficiencies from our depleted farm lands. Such indoor operations provide a grower the ability to more precisely control for temperature, humidity, water and lighting. 

Intematix Corporation announced the commercial availability of ChromaLit® Linear, a remote phosphor offering uniform luminance over any length, high flux density and a sleek, white off-state finish. This product received the Lux Award by Lux Magazine for Light Source Innovation of the Year and recognition by the Illuminating Engineering Society (IES) in its Progress Report featuring the most promising new lighting products.

The maturing of the LED lighting application market has not only seen LED manufacturers aggressively increasing LED luminosity, but also gradually placing more and more attention on the importance in color rendering performance for LED products. Mitsubishi has stated that in the past most sapphire wafers included yellow phosphor in order to create white light, but that the color rendering performance was lack luster. With the evolution of phosphor technology, sapphire wafers to create white light can now also contain green and red phosphor and the same effect happens when UV wafers are paired with red, blue, and green phosphor. This has a clear improvement on color rendering.

Dow Electronic Materials has announced to acquire a private, US-based research company Lightscape Materials, Inc., to expand its LED technology portfolio. But financial terms of the transaction were not disclosed. Major Lightscape Materials' investors included Wisepower, a Korean company, and Silicon-Valley based SRI International. Date back to October of 2011, Dow has announced the formation of a new LED Technologies business segment to capture current and future demand for LEDs in the solid-state lighting market. Aside from  the newly added...
