Light is the most important condition and signal for regulating human rhythms. The intrinsically photosensitive retinal ganglion cells (ipRGCs) primarily respond to light around 480nm, which directly influences melanopsin secretion. Melanopsin plays a crucial role in regulating the circadian rhythm. A high radiance at 480nm helps increase alertness and focus, while a low radiance at 480nm promotes relaxation and prepares the body for sleep.
Therefore, the right balance and intensity of 480nm radiance in the light spectrum are essential for effective circadian rhythm regulation.
YUJI Daylight Spectrum is designed as a neutral white to create a focus-oriented lighting environment. This spectrum effectively restrains melanopsin secretion by covering up to 80% of the ipRGCs sensitivity, promoting alertness and focus. The m-DER 1.044 further enhances this effect, ensuring optimal circadian regulation during daylight hours.
YUJI Nite Spectrum is designed as a warm white to create a relaxing lighting environment. By reducing ipRGCs sensitivity to 26%, it promotes melanopsin secretion, encouraging relaxation and preparing the body for relaxing. The m-DER 0.342 is calibrated to provide perfect lighting for winding down.
The unique design of YUJI circular lighting, combined with advanced spectral technology, offers superior rhythm regulation performance, surpassing traditional lighting and even providing more effective rhythm stimulation than natural sunlight. Compared to traditional lighting and sunlight spectrum m-DER, the YUJI Well24™ spectrum excels in both high and low color temperatures. At high color temperatures, we achieve higher m-DER values, helping to suppress melatonin, boost mental clarity, and improve work efficiency during the day. Conversely, at low color temperatures during the night, lower m-DER values support the natural release of melatonin, promoting rest and a smooth transition into sleep.
Yuji Lighting Intensive Circadian Spectrum is engineered to achieve an 85-95 CRI, ensuring both visual (color reproduction) and invisible (circadian stimulus) effects. This makes it ideal for high-end commercial lighting applications, delivering exceptional color quality without compromising biological function. The relaxing spectrum, with a typical 95 CRI, effectively supports melanopsin secretion, promoting enhanced circadian regulation. These LEDs provide superior color accuracy and biological benefits simultaneously, making them a versatile choice for both aesthetic and health-focused lighting.
