The architect Steven Holl thinks of "sculpting space with light”.

QuarkStar’s Edge-X technology allows one to
​sculpt light itself in space.
"Designed by Steven Holl Architects especially for the display of the important and rapidly growing MFAH collections of 20th and 21st-century art, to which it dedicates more than 100,000 square feet of gallery space, the Kinder Building is the final component in the museum’s eight-year $450 million project to expand and enhance its Susan and Fayez S. Sarofim Campus in the heart of Houston, the largest fine arts building development project of its time in North America."

Museum of Fine Arts, Houston
opens the Kinder Building
featuring QuarkStar's luminaires
​based on Edge-X technology

HOUSTON - QuarkStar, a developer of award-winning LED lighting technologies, announces that its Q-Wall asymmetric linear fixtures were installed in the Nancy and Rich Kinder Building at the Museum of Fine Arts, Houston. Designed by architect Steven Holl, the Kinder building is the centerpiece of an 8-year $450 million expansion and redevelopment project and is currently the largest museum expansion in North America. After an amazing effort to complete it during the covid-chaos of 2020, it is now officially open to the public.
 
Specified by L’Observatoire International and handpicked by the MFAH’s Chief Operating Officer, Willard Holmes, QuarkStar’s award-winning Edge-X technology is installed as the primary exhibit illumination in nearly all galleries using artificial lighting as their primary illumination source.
 
The Q-Wall flawlessly performs in one of the most rigorous and challenging environments for man-made lighting: the galleries of a premier museum. In a world’s first from a commercial general lighting product, Q-Wall uniformly illuminates the expansive 16-ft walls while color-mixing and matching straight from a beam-forming optic that is less than 1-inch wide. Q-Wall’s footprint is so small that when the museum saw it placed in a ceiling mockup, they chose to redesign the cove to take advantage of the empty space that was otherwise unnecessary.
 
“This is what QuarkStar’s Edge-X enables,” CEO Louis Lerman says. “Rather than being forced to design around a fixture, an architectural vision such as the Kinder Building was able to integrate the fixture invisibly while delivering an experience nearly indistinguishable from standing near a window or under their innovative cloud-inspired skylights.

“As Steven Holl has said, he likes to think of his practice in architecture as sculpting space with light. Well, QuarkStar’s Edge-X technology allows us to sculpt light itself in space, creating these beautiful sheets of indirect lighting. We are extremely proud to have been selected for this landmark architectural project.”

 “[U]ltimately it’s about the experience of viewing art together with other people,” Gary Tinterow, director of the MFAH has said. “It’s a building for the long run; the light and space must work 100 years from now.”
 
The Kinder building is the final component of 650,000 square feet of new construction to unify the campus into 14 walkable acres. It will be specially dedicated to installments from the important and rapidly growing MFAH collection of 20th- and 21st-century art and will open with an exhibition highlighting a trove of major collections never before presented in depth.

​Integrated System of Lighting

The Integrated System of Lighting: Paving a New Path to Profitability
Presented by QuarkStar at Strategies in Light in February 2020

The inherent tendency to use familiar design means that the full potential of solid-state lighting technology has yet to be realized. LEDs offer a unique opportunity to develop a new class of fixtures of extraordinary design whereby the source and fixture are one-and-the-same. 

Manufacturers benefit from lower production costs and higher margins while simultaneously offering customers new form factors at lower price points that have superior performance and lifetime. Systems of this integrated nature reduce both cost and complexity, improve reliability and performance, and offer radically new opportunities for integration into the built environment.

​The endpoint is a true systems integration, where separate sources, optics, and fixtures are no longer needed while also offering brand new capabilities. The source and the fixture can become a single unit offering greater beam-shaping, enhanced color stability, and lower costs to manufacture.

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.

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.’
