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.

“The benefits of using Samsung’s LM302N reach beyond the basic lighting function of visual recognition, by improving the non-visual biological effects of lighting on people,” said Un Soo Kim, senior vice president of LED Business Team at Samsung Electronics. “Our LED solutions are ushering in a whole new human-oriented approach of using artificial lighting to enhance productivity and relaxation, benefitting modern-day indoor lifestyles.”

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 minimises disturbances to the natural onset of the body’s melatonin production, helping to promote sleep quality.

Samsung’s LM302N utilises precisely designed light spectra with optimised 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. Standardised at 3.0×3.0mm, 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 per cent below that of conventional LED lighting, the company claims.
