Startup QuarkStar has announced that its Edge-X know-how has been put in all through the brand new Nancy and Rich Kinder Building on the Museum of Fine Arts, Houston (MFAH). The comparatively diminutive optical aspect can unfold LED gentle uniformly over massive areas such as partitions while allowing the solid-state lighting (SSL) fixture to be primarily hidden in a room’s architectural options or recessed into the ceiling. Meanwhile, a multi-channel LED gentle engine allows the museum lighting to match the ample pure gentle that the building design attracts into the public areas and galleries.
The oldsters behind QuarkStar, including CEO Louis Lerman, are a affected person and persistent bunch. The corporate history stretches again a decade or so and we first encountered a non-public demonstration of QuarkStar know-how at Strategies in Light across the 2014 timeframe. The corporate had legendary LED pioneer Roland Haitz on its technology workforce earlier than Haitz handed away in 2015. Other team members embody Eric Bretschneider, who has been an everyday speaker at our occasions, and Bob Steele, who founded Strategies in Light. From the beginning, Lerman insisted the group would change the best way light was delivered, putting photons spatially solely the place desired.
The QuarkStar plan all along was to license its technology to a number of lighting manufacturers. And numerous such manufacturers have experimented with the optics, and maybe are even in confidential growth of products that use the technology. Meanwhile, QuarkStar has continued to turn up at trade events with very compelling demonstrations. For example, at LightFair International in 2019 QuarkStar displayed an interesting cylindrical optic that protruded from a fixture recessed in a ceiling and in addition a version of the edge-X expertise.
The edge-X idea features a linear LED gentle engine that’s mated to the optic. A relatively-skinny, planar gentle-guide-like factor carries the beam from the sunshine engine to the far edge of the optic. While most planar lights disperse a beam perpendicular to the aircraft of the guide, the QuarkStar guide is intended to contain and transmit the beam to the sting. At the sting, the sunshine information mates to the optical diffusing element that is a bit wider than the guide itself. The form of that diffusing aspect delivers the specified beam pattern. We revealed a description. Photo of the optic in a characteristic article back in 2019.
The efficiency of the optic is extra easily described within the context of the museum software. QuarkStar designed the sting-X know-how into a linear wall-wash luminaire called the Q-Wall. The company thought-about partnering with a lighting producer to construct the fixtures, and had 5 potential partners bid on the challenge. Ultimately, the QuarkStar team made the decision to build it themselves for several reasons. The buildout afforded the corporate the chance to continue to evolve the product. The company had equipped a Canadian manufacturing facility able to manufacturing UL-certified products. The difficult museum undertaking required near-steady interaction with the museum workforce that may have been problematic with a third social gathering involved. The museum partitions are sixteen ft high. The Q-Wall luminaire uniformly washes all 16 ft of a wall section with a single luminaire. Litelab directional spotlights with zoom optics permit guests to discern tremendous particulars of the works on display. The museum architects had designed coves stretching several toes from gallery walls. Running linearly the length of the wall to enable the wash impact (see close by photograph). Consultancy L’Observatoire International dealt with the lighting design, and a spokesperson stated the Q-Wall luminaires have been positioned 4 ft 10 in. from the wall to have the ability to uniformly wash the whole wall. Moreover, a clip-on scrim was added to the optic to, as a L’Observatoire spokesperson mentioned, «smooth the optics, needed to realize the standard of mild required for museum-degree lighting.»
QuarkStar has said it could actually accomplish the wall-washing effect with 1 ft of house. Moreover, the sting-X know-how allows the luminaires to be recessed and hidden in a ceiling, though that technique was not utilized within the museum. The optics would only require a 1-in.

«This is what QuarkStar’s Edge-X permits,» stated Lerman. «Rather than being pressured to design around a fixture, an architectural imaginative and prescient such because the Kinder Building was in a position to integrate the fixture invisibly while delivering an expertise practically indistinguishable from standing near a window or under their innovative cloud-inspired skylights.»
QuarkStar was chosen for the mission by lighting consultancy L’Observatoire International and Willard Holmes, MFAH COO. The Q-Wall merchandise are installed to gentle 20,000 ft2 of wall space. The building was designed by Steven Holl architects in partnership with Kendall Heaton.
The three-story museum was envisioned to deliver as much natural gentle into the space as potential. The third ground is lit by the architectural skylights talked about by Lerman that act virtually like a light guide to direct light to circulation down walls. The artificial gentle on the decrease two floors was supposed to match the texture of natural light on the higher flooring. That desire led QuarkStar to ship the two-channel light engines that may vary CCT throughout the day to match gentle from the skylights. The system includes 3000K- and 5000K-CCT channels. And the light guides combine the light uniformly earlier than it reaches the edge.
«As Steven Holl has said, he likes to think about his practice in architecture as sculpting space with mild,» said Lerman. «Well, QuarkStar’s Edge-X expertise allows us to sculpt mild itself in space, creating these lovely sheets of oblique lighting. We’re extraordinarily proud to have been selected for this landmark architectural mission.»
Meanwhile, QuarkStar will proceed to search for lighting manufacturers which may license all or portions of its patent portfolio. That portfolio contains more than one hundred patents simply on Edge-X related technology. The full portfolio numbers far more, covers totally different luminaire ideas, and consists of functions exterior basic illumination including horticultural lighting and automotive. However the MFAH mission also led the company to realize that it wants some manufacturing capacity ready to reap the benefits of opportunities such because the museum. The company said it has now allied with a US-based mostly contract producer to allow more seamless direct providing of luminaires beneath the QuarkStar brand.
