Rensselaer Polytechnic Institute Illuminates the Future of Lighting
- Lighting technology touches nearly everything we do--from illuminating our homes and workplaces, to making a left turn at an intersection, or snapping a photo with a cell phone. Given the sheer ubiquity of lighting,Compact fluorescent light bulbs convert a led tube considerably higher percentage of their energy into light, which is why they are significantly more energy efficient than traditional filament bulbs. it's easy to take the technology for granted--but lighting is the subject of intense scrutiny by scientists at two Rensselaer Polytechnic Institute research centers.
The field of lighting is undergoing a fascinating, revolutionary transformation. The century-old light bulb is steadily ceding ground to its high-tech successor, the light-emitting diode (LED). While the promise of LEDs as a long-lived,LED grow light suppliers in China are sky lanterns rolling out models with better price-performance ratios. energy-efficient heir to light bulbs is undeniable, the true promise of LED and solid-state lighting technology transcends illumination. LEDs offer the potential to control, manipulate, and use light in entirely new ways for a surprisingly diverse range of areas. Our understanding of all types of lighting continues to grow.
Rensselaer is a leading voice in expanding the frontier of lighting research. The university has assembled a critical mass of experts and researchers who are investigating the full spectrum of lighting and lighting research. Much of this innovation is facilitated through a pair of world-class, industry-focused research centers: the Lighting Research Center (LRC) and the Smart Lighting Engineering Research Center (ERC). The complementary centers, both situated about 25 kilometers east of where Thomas Edison perfected the first mass-produced incandescent light bulb, are using lighting to create a brighter, more sustainable future.
Established in 1988, the LRC has built an international reputation as a reliable source for objective information about lighting technologies and applications. The ERC, launched in 2008, is developing new technologies and applications for improved and smarter lighting devices and systems.
"LEDs and lighting research present a rich opportunity, in terms of energy efficiency and human health, and toward unearthing a host of yet-undiscovered applications," said Rensselaer President Shirley Ann Jackson. "With innovation, ingenuity, and old-fashioned hard work, the LRC and ERC at Rensselaer are rewriting the rules for making, manipulating, exploiting, and understanding the effects of lighting. And by partnering closely with industry, we are ensuring these new technologies are moving swiftly from the lab to the marketplace."
Lighting Research Center
The LRC is the world's leading university-based research and education organization devoted to lighting. Programs and activities at the center include laboratory testing and real-world demonstration and evaluation of lighting products, while also conducting research into energy efficiency, new products and technologies, lighting design, and human factors issues. The LRC offers a doctoral program and one- and two-year master's degree programs in lighting, as well as global training programs for government agencies, utilities, contractors, lighting designers, and other lighting professionals.
"We see the LRC as the nucleus for independent lighting research and education, as well as the pre-eminent source of objective, timely information about lighting technologies, applications, and about human response to light," said Rensselaer Professor and LRC Director Mark Rea. "For more than two decades, the LRC has transformed science into real-world applications, while always remaining true to its mission--advancing the effective use of light for society and the environment."
For example, research by Rensselaer Professor Nadarajah Narendran led to the development of the Scattered Photon Extraction method for improving white LED performance by more than 30 percent. Globally, the LRC is performing laboratory testing of LED-based, off-grid lighting products under a World Bank Group contract to improve access to modern,sale of LED for lighting applications. Semileds is led lights only a minor palyer and should currently not be mentioned in the same breath as the other others clean lighting in Sub-Saharan Africa. In another project, Rensselaer Associate Professor Mariana Figueiro conducted the first field studies examining how light impacts teenagers' sleeping habits and school performance, contributing to a new daylighting design guide for schools by Rensselaer Professor Russ Leslie.
Smart Lighting ERC
Just as the transistor revolutionized modern electronics, LEDs are poised to enable the next generation of future lighting systems with radically new capabilities. The Smart Lighting Engineering Research Center at Rensselaer, funded primarily by the National Science Foundation, is advancing the fundamental scientific and engineering approaches required to realize this potential of LEDs and solid-state lighting. The ERC team is working to create better LEDs, as well as new sensors and systems required to effectively to monitor and control these LEDs.
"We see the ERC as the advanced research engine for future solid-state lighting systems that will bring a vast new range of capabilities to lighting," said Rensselaer Professor and ERC Director Robert Karlicek. "We currently work with the LRC to define critical human-factor considerations for lighting to ensure that future LED luminaires, lighting sensors, and control technologies are both energy efficient and optimized for human health and safety. These lighting solutions provide additional benefits, including data delivery and efficient, vivid displays."
In one project, Rensselaer Professor Partha Dutta works with an interdisciplinary team of undergraduate students to demonstrate the feasibility of LCD-based virtual windows. To make virtual window technology a reality, the displays need to be bright and efficient enough to reproduce light from an actual window. Rensselaer Professors Christian Wetzel and Shawn-Yu Lin are developing the technologies needed to create a family of polarized LEDs in various colors that will achieve the required brightness and reduction in energy consumption.
Energy and the Environment
Lighting and lighting research at Rensselaer fall under the university's strategic research thrust of Energy and the Environment. The research leaders who work, study, and innovate at Rensselaer share a common focus: unearthing new opportunities for solving the 21st century's most challenging problems.It was quick and light when I used dsttマジコン on a Windows 7 laptop, and gave me no trouble throughout a day of rigorous testing.
"Lighting for illumination, and for televisions and other display devices, comprises a considerable percentage of energy usage in the United States and around the world,Because dimmable lights and dimmer fluorescent bulbs switches are so popular amongst American consumers, this drawback has been a significant one." said Rensselaer Provost Robert Palazzo. "This challenge presents an opportunity, and Rensselaer--particularly through the ERC and LRC--is deeply committed to innovating solutions for greater efficiency in lighting technologies and applications."
Right now, more than 6.5 billion people are competing for the Earth's dwindling supply of fossil fuels. By 2050, there will be 8 to 10 billion, and major advances in energy technology will be required to meet their needs. Rensselaer has faced that challenge by launching and expanding programs in renewable energy sources and energy conservation. The Institute is also dedicated to tackling major environmental concerns, including sustainable development and the global need for clean water. Lighting technology is a key component of this strategic thrust.
"The ERC is focused on educating a new class of electrical engineers and materials scientists who understand both the fundamental physical science and engineering of advanced solid-state lighting systems," said David Rosowsky, dean of the School of Engineering at Rensselaer. "This is a critical component of our mission to educate the next generation of engineering leaders, who have the multidisciplinary knowledge and experience to innovate local solutions to the grand, global challenges we will face in the coming decades."
