Casambi, the expert in wireless lighting controls based on Bluetooth Low Energy (BLE), has teamed up with Seoul Semiconductor to provide lighting designers with precision control of LED lights that match the spectrum of sunlight. The development puts true human centric lighting in the hands of designers for the first time.

Casambi’s wireless control technology can now be used with Seoul Semiconductor’s innovative SunLike Series LEDs, whose spectra match to real sunlight, to realize human centric lighting.

“Human-centric lighting” describes lighting that is designed to work with the human body’s natural rhythms. It relies on the fact that the human eye detects the presence of a particular wavelength of blue light in the spectrum that makes up sunlight, and uses this to judge what time of day it is. In this way, light helps regulate our sleep–wake cycles and other bodily rhythms, and has a significant impact on our mood and wellbeing.

SunLike series LEDs by Seoul Semiconductor deliver spectrum of sunlight and thus provide similar biological stimulus. Several researches revealed that SunLike LEDs provide up to 21% more stimulus than conventional LEDs at a color temperature of 4000K, and the same stimulus as daylight at 6500K.

The partnership of Casambi and Seoul Semiconductor now provides lighting designers with Bluetooth-based wireless control system and app with products containing SunLike Series LEDs to precisely adjust the level of light, putting human centric lighting into practice.

Timo Pakkala, co-founder of Casambi, commented, “Casambi’s partnership with Seoul Semiconductor puts power into the hands of the lighting designer, who can use their expertise to decide how to customize the lighting to the needs of the particular application and the users of the space, and plan an effective human-centric solution based on the latest science.”
