Lextar's ALLUXIA Leads the Way in Human-Centric Lighting

Lextar Electronics Corp., the vertically integrated LED maker in Taiwan, is setting the trend with human-centric lighting, a combination of LED lighting fixtures with a control system that can simulate day and night to change the color temperature of the light. At the same time, the company also…

Human-centric lighting currently is a focal issue of the Lighting Industry Association (LIA) in Europe. Lextar’s human-centric lighting system comes with a control that can adjust the color temperature of the LED to simulate morning to evening light and create a natural light environment in line with people's physiological rhythm, suitable for use in indoor environments that lack natural lighting. In addition, human-centric lighting can also be used to influence people’s mood and spirit, with warm colors promoting relaxation while cool colors help with contraction and enhance productivity. Lextar will integrate human-centric lighting in its frameless flat panel light series ALLUXIA. ALLUXIA also has won the German Design Award and the Red Dot design award 2016.

In order to enhance the quality of LED light and to show the true colors under the light, Lextar launches its in-house developed “Solar White” LED technology, whose LED wavelength distribution can simulate real sunlight, with an Rf (color fidelity index) of up to 94 and an Rg (color gamut score) of 99.* Lextar's Solar White LED technology generates a light source most closely resembling natural sunlight. It makes indoor, lit environments more comfortable and healthy, and it can truthfully bring out hues and red and blue color saturation.

Lexar CEO Advisor Allen Huang said, "Today's LED market pursues product functionality and cost control, however what’s often overlooked is the importance of light to human physical and mental health. We believe that pursuing the creation of high-quality lit environments to enhance the added value of LED lighting is an important direction. Lextar is currently actively developing such products with brand customers in Europe." Huang added that statistics indicate that people spend about 90% of their time indoors, and thus rely heavily on artificial lighting. Therefore, the theme of Lextar’s booth at the Hong Kong lighting exhibition focuses on improving the quality of indoor lighting. The booth will showcase a wide variety of soft light sources and flat panel light with simple but stylish design. The booth also displays light color temperature tunable fixtures as well as the Solar White LED technology, leading the international trend into a new era of LED lighting.

* In May 2015, the Illuminating Engineering Society of North America (IES) published IES TM-30-15, its new method for evaluating light source color rendition, which made up for the shortcomings of its predecessor Color Rendering Index (CRI). The CRI index cannot fully express the human-eye perception of color. IES TM-30-15 presents the “color fidelity index” Rf and the “color gamut index” Rg as new powerful tools for improving color rendering.
The fidelity index (Rf) is used to indicate the similarity of the standard colors to the reference light source when the test light source is illuminated. The index runs from 0 to 100. The higher the value, the better the color fidelity. The gamut score (Rg) represents the change in saturation of the standard colors compared to the reference source under the test light, and an index value of 100 represents the best possible saturation. The release of the IES TM-30-15 standard is expected to contribute to improved lighting and improved quality of life in lit environments.

Sunlight, UVB and Vitamin D – Human Centric Lighting Beyond Melanopic Stimulation

by Ir. Rémy C. Broersma and Dr. Ir. Marcel P. Lucassen, Scientists at Signify Research Eindhoven UVB radiation initiates vital processes in our body, one of which is the production of vitamin D in the skin. It is well known that over-exposure to the sun may bring a risk. Less well known is that the same is true for insufficient sun exposure due to our indoor lifestyle. In Part 1 of this article, we first describe the scientific understanding behind vitamin D. In Part 2 we describe how artificial light can be enriched with a safe, low dose of UVB, to supplement natural vitamin D production in the skin. Not too much, not too little.

Light in the Service of Health – Bringing the Science of Light and Health into Everyday Life through Evidence-based Communication

Light does far more than let us see. In this episode of the LED professional podcast, Manuel Spitschan and Laura Kervezee, co-chairs of the Light for Public Health Initiative, explain how light acts as the master regulator of the body’s internal clock: it synchronises our physiology with the day outside, shapes mood and alertness, and times the release of melatonin, the hormone that governs sleep. The science is settled enough to act on, so the initiative has distilled it into 26 consensus statements on how light affects the body and well-being, written as practical, evidence-based guidance for individuals, employers, schools and cities. A compact 14-minute briefing on why good light is a public-health question, and what to do about it. Based on the authors’ article in LED professional Review #112.

deLIGHTed Talks #8: Good Light – Good Sleep

Full recording of deLIGHTed Talks #8, held online by LpS DIGITAL on 24 April 2025 (91 minutes). Dr. Renske Lok (Stanford University) shows that bright light during the day deepens nighttime sleep, reduces nighttime awakenings, improves sleep efficiency and lowers next-day sleep inertia. Dr. Jeffrey Hubbard (University of Lausanne / EPFL) compares how light and darkness drive sleep and wakefulness in nocturnal mice and day-active Sudanian grass rats. Chronobiologist Dr. Virginie Gabel, founder of Clock&Me, moderates the session and the discussion on what the findings mean for lighting design.
