Summary of SAMSUNG ELECTRONICS UNVEILS ITS FIRST FAMILY OF ‘HUMAN-CENTRIC’ LED COMPONENTS TO ENHANCE INDOOR LIFESTYLES
Samsung Electronics introduced LM302N, its first human-centric LED packages designed with tailored spectra to modulate melatonin—enhancing alertness (LM302N DAY) or relaxation (LM302N NITE). Standard 3.0 × 3.0 mm packages resist humidity and heat. DAY (3000K–6500K) suppresses melatonin by over 18% versus conventional LEDs for energy and focus in schools, offices, and industrial sites. NITE (1800K–4000K) preserves melatonin—about 5% more release than conventional LEDs—to support nighttime relaxation and sleep quality.
Parts used in the LM302N project:
- LM302N DAY LED package
- LM302N NITE LED package
- 3.0 × 3.0 mm standardized LED package housing
- Humidity protection features
- Heat protection features
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 that 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 the 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.
- What is LM302N?
LM302N is Samsung Electronics' family of human-centric LED packages designed with tailored light spectra to adjust melatonin for alertness or relaxation. - How does LM302N affect melatonin?
LM302N uses optimized cyan amounts in its spectra to either suppress melatonin for alertness (DAY) or minimize disturbance to melatonin for relaxation (NITE). - What is the difference between LM302N DAY and LM302N NITE?
LM302N DAY suppresses melatonin by more than 18% compared to conventional LEDs to boost alertness; LM302N NITE helps maintain melatonin, yielding about 5% more release than conventional LEDs to enhance relaxation. - What color temperatures are available for LM302N DAY?
LM302N DAY is available in color temperatures from 3000K to 6500K. - What color temperatures are available for LM302N NITE?
LM302N NITE is offered in color temperatures between 1800K and 4000K. - What size are the LM302N packages?
The LM302N packages are standardized at 3.0 × 3.0 mm. - Are LM302N packages protected against environmental factors?
Yes, the LM302N packages are protected against humidity and heat. - Where can LM302N DAY be used?
LM302N DAY can be used in indoor applications such as schools, offices, libraries, and industrial sites to enhance awakeness and energy.
