Lighting to energize or relax: new LED packages help improve alertness and the quality of sleep by adjusting melatonin levels
Samsung Electronics unveiled its first “human-centric” LED packages, collectively known as LM302N. Engineered with carefully created light spectra, the LM302N family helps human bodies adjust 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 the cyan wavelength range of light. Brighter cyan-concentrated lighting suppresses the body’s production of melatonin, increasing concentration and enabling a greater overall sense of alertness. Similarly, a lower cyan light intensity minimizes disturbances to the natural onset of the body’s melatonin production, helping to promote sleep quality.
Samsung’s LM302N utilizes precisely designed light spectra with optimized amounts of cyan to accommodate lighting needs to the extent desired at any given point in time: the LM302N DAY improves alertness and the LM302N NITE enhances relaxation. Standardized at 3.0 × 3.0 mm, these offerings can fit in a wide range of lighting fixtures and are protected against humidity and heat.
The LM302N DAY can suppress the body’s melatonin level more than 18 percent below that of conventional LED lighting. Available in a variety of color 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 an individual’s sense of awakeness and energy level.
The LM302N NITE 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 five percent more melatonin under lights with the LM302N NITE packages than conventional LED packages, increasing relaxation. By comparison, spending a lot of time under conventional nighttime lighting can cause excessive alertness that makes it harder to fall asleep. Additionally, the LM302N NITE is offered in color temperatures between 1800K and 4000K, providing design flexibility to bring the benefits of relaxing light to a variety of lighting spaces.
The DAY and NITE packages can also be combined into a single luminaire to help people maintain their natural circadian rhythm 24 hours a day. This duo-lighting option is optimal for those who spend most of their time indoors and struggle with confused body clocks.
The newly launched LM302N family is now in mass production.
