Share

Seoul Semiconductor Co., Ltd. (KOSDAQ:046890), a leading global innovator of LED products and technology, announced that its SunLike Series natural spectrum LEDs have been identified as a key light source for promoting human well-being, based on the results of a recent comprehensive sleep study conducted by scientists at the University of Basel.

Seoul Semiconductor developed SunLike Series natural spectrum LEDs in collaboration with Toshiba Materials’ TRI-R spectrum technology in 2017 as the first LED light source to closely match the spectrum of natural sunlight. The two companies have since promoted this natural sunlight spectrum technology through its favorable effects on human well-being and sleep as a key value in the evolution of lighting.

There has been an increase in research activity on the relationship between light and human bio-function, including a recent scientific study focusing on the effects of light spectrum on sleep quality, visual comfort, well-being and daytime alertness conducted by Prof. Christian Cajochen and his team at the University of Basel in Switzerland, entitled: “Effect of Daylight LED on Visual Comfort, Melatonin, Mood, Waking Performance, and Sleep,” published in the Journal of Lighting and Research Technology published on March 24, 2019.

It is well established that light is one of the strongest control factors for human circadian rhythms, such as the secretion of the sleep promoting hormone melatonin. Thus, optimal lighting condition during daytime are crucial to prevent circadian rhythm disturbances which can lead to sleep disorders and other life-style related diseases. Over the past ten years, there have been related scientific studies in the fields of sleep, chronobiology, physiology, as well as the impact of light quality in elderly care.

According to Prof. Cajochen’s research, LED light sources with the same measured correlated color temperature (CCT) and intensity, but different spectral output, can have different effects on human behavior and physiology. LED light sources with a spectrum close to natural sunlight produced better visual comfort, more alertness, and happier moods in the morning and evening among the test participants, compared to those exposed to conventional spectrum LEDs. The research tested subjects’ visual comfort, circadian physiology, daytime alertness, mood, cognitive performance, and sleep after being exposed to both conventional LED light, and natural spectrum LED light for 49 hours in a laboratory setting.

Quoting from the paper: “We have evidence that a daylight [natural spectrum] LED solution has beneficial effects on visual comfort, daytime alertness, mood, and sleep intensity in healthy volunteers. Delta EEG activity (0.75–4.5Hz) was significantly higher after daylight-LED than conventional-LED exposure during the post-light exposure night.” [NOTE: Delta EEG (electroencephalogram) measurements record delta waves, the brain waves associated with Stage 3 non-rapid eye movement (NREM) sleep, or “slow-wave sleep” (SWS), and aid in characterizing the depth of sleep.]

By providing the same spectrum as sunlight and in the visible light range, SunLike Series natural spectrum LEDs deliver benefits to human well-being, consistent with the mechanisms of vision that impact both image forming and non-image forming aspects of the eye, as well as the control of circadian rhythms. While the qualities of artificial light have been described primarily with color and intensity thus far, SunLike Series natural spectrum LEDs have introduced light spectrum as another important factor in determining overall light quality.

“This research conducted by the University of Basel suggests another important aspect to the evolving direction of artificial light over the past eighty years. In addition to the properties of energy efficiency and long life, we have added the factor of ‘human well-being’ to modern LED light sources,” said Nam Ki-bum, sales executive vice-president of Seoul Semiconductor. “As the world’s first mass-produced LED devices to achieve natural sunlight quality, SunLike Series LEDs are advancing lighting technology in this important area as we continue to respond to market needs from our customers’ lighting applications.”

EURid Launches New Eligibility Criteria19.10.2019 04:30:00 CESTPress release

The top-level internet domain .eu is the eighth largest country code extension on the internet and, as of October 2019, we have more than 3.6 million registrations spread out across Europe. Since its launch in 2006, only companies and individuals residing within the EU and EEA member states have been eligible to register the .eu domain name. However, striving to meet the needs of an ever-changing digital environment, the eligibility criteria for the registration of .eu domain name has now been extended to all EU citizens living around the world. With millions of Europeans living around the world – our hope is to provide these individuals, living far from their native lands, with a personal online platform through which they can share their stories with families and friends back home. “We are excited to be able to extend the registration criteria to EU citizens around the world. The .eu domain is now closer to your ambitions, achievements and dreams. It is the bridge connecting you to y

New Research Reveals Updated Patient Preferences on Digital Health Technology18.10.2019 13:00:00 CESTPress release

ResMed (NYSE: RMD, ASX: RMD) today announced results from a company-led survey, revealing new patient preferences on digital health technology. The survey highlights a reason for optimism that the markets for digital health technology will only continue to grow. The survey of a nationally representative sample of 3,000 Americans, conducted in partnership with Edelman Intelligence, revealed that the use of – and confidence in – remote digital health technology is widespread: 56% of those surveyed currently monitor their health with at least one digital data collection tool. Also, 60% of people attempt to diagnose themselves after browsing symptoms on the Internet – including 76% of Millennials. Perhaps more surprising, remote digital health technology seems to have deepened people’s connection with their physicians rather than distanced them from one another. Over half of those surveyed agree that technology has improved their relationship with their primary care provider, and many woul

CHMP Grants Positive Opinion for Expanded Use of Janssen’s Darzalex®▼(daratumumab) for Patients with Newly Diagnosed Multiple Myeloma Who Are Transplant Ineligible18.10.2019 12:43:00 CESTPress release

The Janssen Pharmaceutical Companies of Johnson & Johnson today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended broadening the existing marketing authorisation for Darzalex® (daratumumab) to include the use of daratumumab in combination with lenalidomide and dexamethasone (DRd) for patients with newly diagnosed multiple myeloma (NDMM) who are ineligible for autologous stem cell transplant (ASCT). “As multiple myeloma can become more complex with each relapse, it is important that patients receive the latest treatment options with the goal of extending their first remission period,” said Professor Thierry Facon, M.D., Service des Maladies du Sang, Hôpital Claude Huriez, Lille, France, and principal investigator of the MAIA study. “For newly diagnosed patients who are transplant ineligible, this regimen could be an important frontline therapy option and reinforces the consistent clinical profile of daratumuma
