NICHIA launched a new and improved Circadian Tunable LED offering. This new tunable LED pairing has been developed to enhance the regulation of your Body Clock by combining both the stimulation and calming doses, in addition to colour tuning.
This Circadian Tune technology harnesses NICHIA’s expertise in developing a unique Phosphor Converted Cyan, among other semiconductor processes and packaging techniques. The supplementary component is the inclusion of NICHIA’s newly launched LEDs with TriGain technology, a potassium fluorosilicate (PFS) based phosphor technology licensed to NICHIA through a strategic partnership with GE Current.
NICHIA’s new Circadian Tune LED products will raise the bar to also address efficacy, colour quality and increased Melanopsin Stimulation, the light that explicitly targets melanopsin-containing neurons in the retina of the eye. These neurons, called Intrinsically Photosensitive Retinal Ganglion Cells (ipRGCs), are connected to a region of the brain responsible for regulation of the 24-hour circadian cycle along with associated reflexive neuronal and hormonal responses to the presence of light.
Sensitive to a particular range of wavelengths, melanopsin photoreceptors reach peak light absorption at wavelengths around 490nm. By utilizing NICHIA’s Phosphor Converted InGaN Cyan, NICHIA’s Circadian Tune LEDs are optimized at the most sensitive wavelength of ipRGCs. Indeed, this approach provides a higher performance through its unique combination of lumens per watt (lpW), TM30 and Melanopic Ratio (MR) than other human-centric lighting solutions.
Using NICHIA’s new Circadian Tune technology, the high MR and cooler CCT will reduce fatigue and provide greater alertness to help office workers remain in an awakened state of mind or help night workers complete their shifts effectively. At a low MR and warm CCT, the focus switches to relaxation, prompting a feeling of safety and initializing a transition to sleep. A sense of time is therefore introduced when both proper melanopsin stimulus and variable CCT is being applied.
Satoshi Okada, General Lighting Business Planning Manager, NICHIA Japan, said: “New Circadian Tune LED products are truly innovative. Through an optimization of efficacy, colour quality and Melanopsin Stimulation, we can better target ipRGCs. Additionally, the utilization of a traditional 80 CRI warm white for the relaxing portion limits the colour quality of the system. To overcome these limitations, NICHIA has introduced this Phosphor Converted Cyan and Warm White TriGain pairing.
NICHIA introduced Vitasolis in 2019, a range of LEDs geared to suppress fatigue and boost vitality. The Circadian Tune LED pairing builds on these innovations to offer a more dynamic and tunable solution to the global lighting industry.”
