source of light over incandescent bulbs and compact fluorescent lamps, due to their low energy consumption and extended lifetime.
The expanded TMAL unit is expected to be completed in the third quarter of 2013, while the new TMG plant will be ready in August 2014.
Red nitride LED phosphor patent granted to Intematix
The firm’s chemical formulation lowers the concentration of oxygen impurities in the material structure. This leads to improved reliability under high temperature and humidity conditions and increases light output efficiency
Intematix Corporation has been issued its patent covering red nitride phosphor compositions used in LEDs by the United States Patent and Trademark Office (USPTO).
The patent was allowed in August and officially issued on September 25th 2012.
Intematix’s U.S. Patent No. 8,274,215, entitled “Nitride-based Red Phosphors” is the 18th U.S. patent issued to Intematix in the area of LED phosphors and the 71st U.S Patent overall.
LED manufacturers worldwide have implemented Intematix’s red nitride product portfolio in order to produce high performance and quality lighting products.
“Our novel chemical formulation lowers the concentration of oxygen impurities in the material structure, leading to improved reliability under high temperature and humidity conditions,” explains Yi-Qun Li, Chief Technology Officer at Intematix, “This design increases light output efficiency and produces longer emission wavelengths when powered by the blue light from the LED chip.”
Red phosphor technology plays a fundamental role enabling high quality LED lighting with high colour rendering index (CRI). Due to the high thermal stability of nitride technology in particular, LEDs may operate at higher temperature, power and light output per unit, lowering the costs of lighting.

New UK homes to benefit from PhotonStar LED lighting
The British designer and manufacturer of smart LED lighting solutions will supply many new homes in the UK in order to meet new regulations to reduce CO2 emissions
PhotonStar LED has announced a rolling one year exclusive supply agreement with a major UK house builder to supply LED lighting fixtures for all of the developer’s new homes.
The products will be supplied through UK wholesalers.
In the last year, the house builder completed 1500 homes, and is forecasting continued growth. All new properties will be subject to new legislation requiring improvement in energy efficiency including lighting.
The new legislation, “Code for Sustainable Homes,” is an environmental impact rating system for housing in England and Wales. The first level (3) of the code has recently become mandatory on all new properties, with increasing targets for CO2 emission reduction over the next four years.
Developers have a number of choices on how they will achieve these reductions.
Following extensive testing over a one year trial, PhotonStar was able to successfully demonstrate cost effective (on a cost per plot basis) CO2 emission reduction in multiple property types through a lighting upgrade.
The financial terms of this contract have not been disclosed, but are expected to have an increasing impact as the House Builder moves to the new property designs.
James Mckenzie, CEO of PhotonStar LED Group PLC, comments, “We are delighted that they have now received the endorsement of a major UK house builder. It also serves as a credible introduction into new wholesale stockists”
PhotonStar LED Group PLC, based in Romsey, Hampshire with manufacturing in Wales, is a designer and manufacturer of smart LED lighting solutions. The group’s proprietary technology
