Phenikaa Group announced the successful development and application of "Natural Lighting Technology - Phenikaa Natural TrueCircadian" - A technology that creates high-quality light sources that mimic the spectrum of natural sunshine and is optimized for human eye absorption

Ha Noi, Following the excellent development of core technologies in the 4.0 technology era, such as: map technology (BusMap – Phenikaa MaaS), self-driving technology (Phenikaa-X), Phenikaa Group (A&A Green Phoenix Group Joint Stock Company) has successfully conducted research, development and application of "Natural Lighting Technology – Phenikaa Natural TrueCircadian” – the foundational technology that enables the creation of world-class light sources with the closest light spectrum to natural sunlight, as well as enhanced and optimized biological spectrum regions for human eye absorption. The technology was researched and developed by a team of scientists from Phenikaa University, engineers from Phenikaa Electronics Joint Stock Company, and lighting experts from the Phenikaa Group.

With the orientation of becoming a leading technology-industrial corporation in the field of smart devices, solutions, and smart production systems, the Phenikaa Group has always made significant and long-term investments in research and development (R&D) with the goal of developing core technologies, then mastering and applying them in production to create world-class, high-quality, cutting-edge technology products that meet critical societal needs and compete effectively in domestic and international markets.

The world's history of LED lighting technology went through two stages: the stage of completing technology and lowering LED chip production costs (1990-2010); the stage of improving efficiency, increasing production scale, and intelligent control (2011-2018) in order to move into stage 3, the stage of light quality competition. LED light sources must now meet not only energy efficiency but also high quality standards: the color rendering factor (CRI) of 90 or higher, rather than CRI 80 as in conventional LEDs; the color reflect vividly with true-to-life colors, particularly the R9 index (with a R9 index > 45, as opposed to a negative R9 value or close to zero in conventional lights); Additionally, mainstream technological trends during this time period emphasize the development of light sources that respond to both human visual and non-visual perception (perceptions related to health and psychophysiology) as well as the development of lighting technologies that influence and adapt to human circadian rhythms.

Natural Lighting Technology "Phenikaa Natural TrueCircadian" with a Human Centric Lighting - HCL approach, developed by the Phenikaa Group's team of scientists, engineers, and lighting experts, represents a significant step forward in today's LED lighting industry. To develop top-quality lighting sources that most accurately reproduce natural sunlight while also having a positive impact on circadian rhythms and human health, the scientists and lighting experts at Phenikaa conducted a comprehensive and systematic study of the solar spectrum, human evolution associated with forest and grassland, and the spectrum of direct and scattered light on vegetation in a variety of environments (grasslands, forest, under trees, etc.) to optimize LED specifications for different environments, spaces and applications.

Cyan LEDs, which emit light in the 460-500 nm wavelength range, are the technological breakthrough in Phenikaa's natural lighting system (Patent No. 29668 in 2021). This is also the wavelength range of Melanopic light absorbed by photosensitive retinal ganglion cells (ipRGC), a type of cell responsible for human circadian rhythm regulation. The development of blue-green LED chips addressed a long-standing limitation in the light spectrum of conventional LEDs, namely the concave region in the wavelength range of 460-500 nm - which is the primary contributor to the reduction in the light quality index of light sources - enabling LEDs with a higher color rendering index, greater color temperature adjustment flexibility, a high R9 color index, and, most importantly, a light spectrum that is compatible with circadian rhythms (with high biological light index M/P), maintaining body health and optimizing visual and non-visual perception.

Along with the blue-green LED (Cyan LED) invention, five other patents have been registered for intellectual property protection, including: Green LED; blue LED and blue LED manufacturing process; Green white LED; HCL LED (Human Centric Lighting); Light-emitting LEDs that simulate natural daylight in the horizontal direction (Horizontal Sunlight) comprise a Phenikaa intelligent integrating technology platform that will enable the development of an entirely new generation of LED lights: the highest color rendering index (CRI) of 97/100, the highest R9 index of 95/100, the highest biological impact index (M/P) of 1.18 (the highest value in the world today). The highlight of Phenikaa lighting products is that they achieves high values for all 4 important light source indicators in one: high efficiency, high light quality (high CRI, high R9), and high biological impact index (high M/P) – thus resolving the paradox of “the more increasing light quality, the less decreasing light efficiency” in LED lighting technology.

Up to now, Phenikaa is the country's initial manufacturer to provide indications in connection with light source quality and LED standards for human health: those are CRI, R9, and M/P – which promise to usher in an era of high-quality, natural, and balanced light for human health.

Accompanying with natural lighting technology - Phenikaa Natural TrueCircadian Technology, Phenikaa Group has timely invested in and put Phenikaa Electronics Smart Factory into operation in Hoa Lac Hi-Tech Park, a smart factory equipped with European and Japanese technology. The factory is invested in a synchronous and systematic manner from the stage of research, development, testing, and inspection to the intelligent production system and intelligent management, including chip packaging and production of optical materials supporting chip packaging, these are to manufacture electronic circuits, smart robots, smart electronic devices, and smart lighting devices for human health (HCL). Together with the synchronous factory system mentioned above, Phenikaa's Natural TrueCircadian Technology enables the creation of high-quality smart LED products that provide suitable, natural, balanced light for circadian rhythm and human health at an affordable price.

Adhering to the business philosophy of "Realizing all commitments" and the aspiration to always be a pioneer and innovator in the research and development of new products, the Phenikaa Group continues to bring to the community one-of-a-kind products with the most outstanding, safe, economical, and user-friendly features, all branded with a new technology, "Phenikaa Natural TrueCircadian Technology”. Phenikaa's aspiration is to not only provide users with a perfect light quality experience but also to contribute to raising awareness about the impact of light on human health, and light standards, as well as to change usage behavior toward high-quality lighting solutions.
