Materials and footprint options multiply in LED optics
|
SSL remains a multidisciplinary development effort and optics can be as important as LEDs in delivering quality of light. MAURY WRIGHT surveys some of the latest LED-centric optics options for general lighting and specialty applications.
QuarkStar Edge-X by Maury Wright At the end of the day, optics in SSL applications serve the primary task of controlling beam distribution. Our final company in this article takes that task to a new level. QuarkStar is a late-stage startup company with a business plan focused on licensing optics technology to luminaire makers. The company, however, has developed some compelling demonstration optics, especially Edge-X for general illumination applications. The Edge-X optics combine light guide functionality that serves as a way for photons to travel from an LED light engine to the edge of the optic, where the company’s patented technology then forms the desired beam pattern delivering light just where it is needed. The nearby image shows the transparent planar light guide between the light engine and the beam-forming edge optics. Feilo Sylvania became the first SSL manufacturer to license the QuarkStar technology earlier this year. [ Read on LEDs Magazine ] |

Light and Innovation
The new entrants who are transforming lighting Will lighting be taking a new course? The arrival of the LED and digital lighting, which are completely redesigning our approach to lighting, is an obvious step in the revolution occurring in this sector. And the power of electronics, coupled with the creative human imagination, keeps pushing back the limits of the possible with completely new solutions - some of which are akin to technological breakthroughs. Indeed, some of the solutions presented in this selection completely change the conceptual approach to lighting or the infrastructure of lighting like, for example, a direct/indirect light downlight (QuarkStar), street lighting powered by kinetic energy (Engoplanet), an infrastructure for interior lighting that is free of drivers (Illuma-Drive). Designed by actors (many of whom do not come from the lighting sector) who think about light in new ways, these innovations compete with established ways of doing things via a common idea: to improve offerings by reducing energy consumption and environmental footprint. And technology has obviously not reached its limits: from start-ups to global electronics and communication giants, and including the more legacy industrial companies, many are interested in the potential of digital light and are investing in it. |

QUARKSTAR: NEW GENERATION DISTRIBUTIONS
Holder of numerous patents, winner of many awards, the American start-up QuarkStar has completely rethought LED lighting in order to surpass current performances at all levels. Their technology Edge-X technology, notably seen at Light + Building 2018, revolutionizes light distribution, using refraction rather than reflection, opening the way to designs that were up to now unimaginable, like this semi-recessed downlight to direct / indirect lighting. |

FEILO Sylvania has licensed a ground-breaking lens technology which it plans to include in its next generation luminaires
The company has signed a deal to get access to the radical Edge-X technology from innovative US start-up QuarkStar.
It’s understood the company will initially use the ‘light shaping’ lens development in its downlight and linear lighting ranges under the Concord brand.
The Edge-X optics essentially guide the output from LEDs and sculpt the distribution of light in a space. One of the benefits to clients is that fewer luminaires are needed in a space to get the same effect as traditional optics.
‘Seeing the capability of Edge-X optics was a significant moment for us,’ Sylvania’s technology chief Richard Turner told Lux. ‘We knew immediately that incorporating the optical technology into our product lines would be a major win. This was confirmed by our jointly winning Lux’s Top 20 Innovations Award at the 2018 Light + Building for the first major revolutionary advance in downlights in 75 years.’
‘Sylvania’s ability to incorporate the Edge-X technology into a full product line will enable it to significantly increase its position in the market,’ QuarkStar Louis Lerman told Lux. ‘This agreement brings together QuarkStar’s globally patented, award-winning technologies with the power and presence of the Sylvania brand.
‘QuarkStar’s unique combination of novel functions and radically new designs will provide significant market differentiation across multiple product families.’

QuarkStar's solution of the unsolved major problem of color shift prediction contributes to new industry standards from LEDS Magazine (Carrie Meadows):
Predicting Chromaticity Shift in LEDs and SSL Products " ... [QuarkStar's model] has the potential to change how the solid-state lighting (SSL) industry utilizes test and measurement guidance, and effectively end the notion that the lumen is the only light characteristic that matters with regard to LED lifetime performance." Watch webcast (To skip registration, use this email: QS_color_shift_control@quarkstar.com) This webcast will provide an overview of how the SSL design process can be enhanced by predicting chromaticity shift. Product developers and lighting specifiers will learn how such a data-driven method might be employed to help them choose products carefully and to confidently deploy SSL technology in color-critical applications.
