Samsung Electronics’ LM302N LED packages are engineered with a carefully-tailored light spectrum to help adjust human melatonin levels indoors, making people feel more energetic or relaxed depending on their daily life patterns.
Melatonin, a hormone which regulates the sleep-wake cycle, responds to cyan light. More cyan in the output of a light source suppresses the body’s production of melatonin, increasing concentration and enabling a greater overall sense of alertness. Lower cyan content minimises disturbances to the natural onset of the body’s melatonin production, helping to improve sleep quality.
The LM302N LEDs give precisely designed light spectra with optimal amounts of cyan to accommodate lighting needs on both sides of that equation; the LM302N DAY improves alertness, while the LM302N NITE enhances relaxation. The DAY package can suppress the body’s melatonin level more than 18% below that of conventional LED lighting.
Available in a variety of colour temperatures from 3000K to 6500K, the DAY package can be used in a diverse range of indoor applications such as schools, offices, libraries, and industrial sites, to enhance awakeness and energy level.
The NITE package, on the other hand, can provide a proper level of brightness without hindering the release of melatonin, helping people to maintain the hormone level as if they were in a calm natural atmosphere at night. The body releases about 5% more melatonin under lights built around the NITE package than with conventional LED lights. It’s come under increasingly concerned scrutiny that spending a lot of time in conventional LED light that isn’t cyan-reduced can cause excessive alertness that makes it harder to fall asleep. The NITE package is offered in colour temperatures between 1800K and 4000K, providing design flexibility to bring the benefits of relaxing light to a variety of lighting spaces.
