Lighting Design on the Moon

What does lighting design look like on the Moon? Danish lighting brand Louis Poulsen partnered with SAGA Space Architects to answer this question.

What does lighting design look like on the Moon? Danish lighting brand Louis Poulsen partnered with SAGA Space Architects to answer this question.

SAGA specializes in research and design for future space habitation. With the goal of developing the best Moon habitat for humans, not just trained astronauts, SAGA launched LUNARK – a simulated Moon habitat for research, with the aim that it one day can sustain life on the Moon. Part of their research was on circadian rhythm and lighting’s impact on wellbeing. They partnered with Louis Poulsen to develop special lighting panels for their research.

LUNARK

From September to November 2020, LUNARK, the deployable habitat, was tested on an analog Moon mission near Moriusaq, Greenland in the high Arctic. Sebastian Aristotelis and Karl-Johan Sørensen from SAGA deployed the habitat and lived in it for 60 days, completely isolated. During the expedition, the habitat sustained a comfortable living environment while enduring Hurricane scale winds, snow-storms, and temperatures down to -30°C.

A key factor for psychological and physical well-being is the need for a stable circadian rhythm, which the Moon lacks due to its 28 day-night cycle. In partnership with Louis Poulsen, SAGA created custom-made Circadian Light Panels to bathe the interiors in pseudo-natural daylight, accurately emulating the subtle hourly variations of natural daylight on Earth. The circadian lighting system in the habitat is a completely automated system developed to aid in human well-being in extreme environments. Sleep disruptions and out-of-sync circadian rhythms make astronauts lethargic and unproductive. The Circadian Light Panels on the ceiling simulate varying weather and daylight conditions. There were two challenges to solve with the Circadian Light Panels – stimuli and circadian rhythm.

Stimuli

In space, every day is the same, your senses become numb, your cognitive abilities deteriorate. You quickly start to lose your sense of time. The Circadian Light Panels combat this by adding variation, by emulating the daily cycle of natural sunlight. SAGA simulated all the phases of a natural light environment: dawn, sunrise, daylight, sunset and dusk. To combat monotony even further, the panels were also programmed with variation between the days to mimic various weather patterns we experience on Earth, from overcast and low light intensity to brighter, high intensity warm light.

Circadian rhythms

A healthy circadian rhythm is one of the most impactful ways to maintain good well-being. On the Moon, this is challenged as the sunlight environment is very different. If you are at the equator of the Moon, you’ll experience 14 days of sunlight followed by 14 days of darkness; at the south pole of the Moon, there’s almost always sunlight. The crew of LUNARK experienced similarly difficult light conditions by being close to Earth’s North Pole in the Arctic circle. Simulating a healthy circadian rhythm stimulates natural sleep and wake hormone production in the body. Lowering the intensity of blue light towards the evening promotes production of the sleep hormone melatonin production, and likewise waking up to increasing blue light suppresses melatonin and promotes cortisol.

Citing Research, Kenall Claims Indigo-Clean Inactivates SARS-CoV-2 and Influenza-A

Kenall recently announced that its Indigo-Clean technology is proven effective in killing both SARS-CoV-2 and Influenza-A in recently conducted independent lab testing.

Kenall recently announced that its Indigo-Clean technology is proven effective in killing both SARS-CoV-2 and Influenza-A in recently conducted independent lab testing. Previous research indicated that Indigo-Clean also kills harmful bacteria, such as Staph, including MRSA2.

Indigo-Clean uses 405nm visible light, rather than UV light, to continuously disinfect the air and surfaces, killing harmful viruses and bacteria. Unlike UV, Indigo-Clean does not harm people or degrade materials, making it well-suited for areas such as hospitals, medical centers, quick care facilities, schools, prisons, jails, public restrooms, and more, according to Kenall.

Kenall has expanded the available technology series, now offering three types of disinfection lighting for various applications.

1. Indigo-Clean EX series reportedly kills 99% of SARS-CoV-2 and is also effective against C. diff
2. New Dual-Mode Indigo-Clean technology series provides blended white and indigo-only modes, which reportedly kills 94% of SARS-CoV-2 and Influenza-A with 12/12 hour operation
3. Single-mode Indigo-Clean technology series provides pleasant, ambient illumination and continuous disinfection while the light is on

ELECTRICAL WHOLESALING Breaks Down GUV Lamps

Joe Knisley breaks down germicidal ultraviolet lamps in this article appearing in ELECTRICAL WHOLESALING.

Joe Knisley breaks down germicidal ultraviolet lamps in this article appearing in ELECTRICAL WHOLESALING.

As electrical wholesalers learn more about this this fairly new product category of disinfectant lighting, they will learn that GUVs require new design and installation techniques and more stringent safety features in many cases.

Distributors should also recognize that right now there’s a bit of a “Wild West” atmosphere with GUVs because some unscrupulous vendors are selling shoddy products (especially directly to consumers) and are making exaggerated claims. This takes away from the lighting developing and selling germicidal lighting products with solid engineering and safety features.

The Light and Health Research Center now has an online presence with a section on its parent organization Icahn School of Medicine at Mount Sinai’s website.

The Light and Health Research Center was founded by Dr. Mariana Figueiro, who made a significant impact on the lighting industry in her role as director of the Lighting Research Center. She now heads up the Light and Health Research Center as Director and Senior Faculty, Population Health Science and Policy.

The mission of the organization is stated by Dr. Mark Rea:

Among the many projects underway, we are looking at how robust patterns of light and dark improve sleep for people from many walks of life, from submariners to premature infants to senior citizens and, indeed, to all who work in offices, schools, and factories. We are developing lighting schemes to improve the lives of those living with conditions like Alzheimer’s disease and depression, and those who are undergoing cancer treatment or recovering from traumatic brain injury. We are also exploring the science and application of ultraviolet light to improve vitamin D production in populations who do not get enough sunlight, to control agricultural plant pathogens, and to serve as a germicidal disinfection strategy in the built environment. We are also developing new lighting technologies for safer transportation, from less glaring and more effective lighting for emergency vehicles to airport ground lighting that is better visible to pilots.

DesignLights Consortium Seeks Proposals to Assess and Characterize the LED Light and Wellness Commercial Lighting Market

The DesignLights Consortium (DLC) has issued a Request for Proposals (RFP) seeking consultant services to assess and characterize the commercial market for LED light and wellness products. Proposals are due March 29 (date corrected per updated press release).

The DesignLights Consortium (DLC) has issued a Request for Proposals (RFP) seeking consultant services to assess and characterize the commercial market for LED light and wellness products. Proposals are due March 29. (Date corrected per updated press release)

“This market assessment comes as the DLC is in the midst of implementing new Solid-State Lighting Technical Requirements that encourage development and deployment of lighting that provides non-energy benefits such as improving end-user comfort,” DLC Executive Director and CEO Christina Halfpenny said. “We are confident this project will yield data to further inform our efforts to support products that improve the wellbeing and satisfaction of people in the built environment.”

The DLC is defining lighting for wellness as “optical radiation that stimulates the circadian, neuroendocrine and neurobehavioral systems in humans” as defined by the TM-18-18 publication from the Illuminating Engineering Society. The DLC Light and Wellness Market Assessment will focus on products designed and marketed to provide circadian lighting attributes such as differentiated spectral power distribution, color tuning to support different time-of-day protocols, optimized spatial distribution to increase vertical illuminance levels at the eye, and/or controllability that supports one or more of these attributes.

The project will cover the commercial office, education (K through higher education) and health care (including nursing and long-term care facilities) segments of the commercial lighting market. It does not include germicidal and antibacterial/antimicrobial lighting products, products marketed for light therapy, or product categories not included on the DLC’s Solid-State Lighting Qualified Products List (such as consumer- and residential-grade products).

Services sought through RFP include identification of both market trends and barriers related to light and wellness products for the next five years. Among the issues the DLC is seeking to better understand are how market trends intersect with energy efficiency and controllability; how market trends may have changed due to COVID-19 impacts; whether barriers differ among market segments; and if there are barriers specific to the distribution chain. Those and other questions will be answered in a final report in late August 2021.
