New DOE Report Estimates Energy Savings Potential of SSL
SSL Energy Saving Potential | February 17, 2009
The U.S. Department of Energy (DOE) has released analysis findings of the energy savings potential of solid-state lighting (SSL) sources for general illumination applications compared to conventional light sources (e.g., incandescent and fluorescent). Using an econometric model of the U.S. lighting market, the February 2010 report estimates national energy savings if SSL technology achieves certain forecasted price and performance objectives..

Cree Breaks 200 Lumen Per Watt Efficacy Barrier 
White High Power LED | February 04, 2009
Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announces another industry-best reported efficacy record of 208 lumens per watt for a white power LED. This R&D result passes a significant milestone within the solid-state lighting industry as well as demonstrates Cree’s relentless drive to increase the performance of its LEDs.

Cree Study Shows LED Lighting is Best Bet for Energy Efficiency  
LED Life-Cycle Energy Usage  | December 18, 2009
A new report on the life-cycle energy usage of energy-efficient lighting by Cree, Inc. shows that LED lighting products are now more efficient than traditional lighting products when compared across the high-volume applications of recessed downlighting and display spotlighting. Evaluating light fixtures and applications, the white paper’s energy comparisons demonstrate that LEDs offer clear advantages in terms of energy costs and environmental impact over traditional lighting such as incandescent, halogen and compact fluorescent bulbs.

Cree Achieves 186 Lumens per Watt from a High-Power LED
White High Power LED | December 02, 2009
Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announces it has achieved industry-best reported R&D results of 186 lumens per watt for a white power LED.

Scientists at 3M have unveiLed a color-conversion technology that doubles the efficiency of green LEDs, compared with currently-available green emitters. The St. Paul, Minnesota-based company says that the technology could lead to accelerated adoption of LEDs in demanding applications such as LCD display backlights and pico-projectors.

OSRAM Opto Semiconductors has developed an LED that offers high efficiency, excellent color rendering and a pleasant warm white light. The prototype is the first to offer the three important properties that together are essential for general illumination applications, namely a color temperature of 3000 K, a color rendering index of 82 and an efficiency of 104 lm/W.

The U.S. Department of Energy (DOE) has published a Solid-State Lighting Manufacturing R&D Roadmap, the end product of two stakeholder workshops sponsored by DOE in 2009. The Roadmap represents industry consensus on the expected evolution of SSL manufacturing, best practices, and opportunities for improvement and collaboration.

A new process for creating ultrathin, ultrasmall inorganic light-emitting diodes (LEDs) and assembling them into large arrays offers new classes of lighting and display systems with interesting properties, such as see-through construction and mechanical flexibility, that would be impossible to achieve with existing technologies.

An OSRAM Opto Semiconductors` study on the life-cycle assessment (LCA) of LED lamps shows the latest generation of lamps achieves a very high score for environmental friendliness.
