Casambi, a pioneer in Bluetooth Low Energy (BLE) wireless lighting control, has teamed up with LED technology specialist Seoul Semiconductor to offer lighting designers precise control of LED strips, modules and luminaires that use the new SunLike technology that matches the spectrum of sunlight. For the first time, this development puts true human-centered lighting in the hands of designers.

Users can use Casambi's Bluetooth-based wireless control system and app with products that include SunLike series LEDs to precisely adjust the light level, knowing that the spectrum reflects real sunlight, a key ingredient for Human-centric lighting

Human-centric lighting describes lighting designed to work with the natural rhythms of the human body. It is based on the well-known fact that the human eye recognizes the presence of a certain wavelength of blue light in the spectrum of sunlight and derives the time of day from this. In this way, light helps to regulate our sleep-wake cycles and other physical rhythms and has a significant impact on our mood and well-being.

Human-centered lighting takes advantage of this effect by adjusting its brightness and color temperature during the day to mimic natural light.

Casambi allows control of the lights through a timer or a variety of presence/movement sensors and daylight sensors. It can control lights that change colour temperature over a very wide range, and designers have the freedom to configure dimming and create scenes or animations for the application.

The new Color Tunable Series from Nichia are game-changing single surface, tunable white LEDs that allow the user to smoothly transition color temperature from warm white to cold white.

The series are ideal for many applications, such as commercial, retail spot lights and residential downlights. Retail stores can change the light color based on their display or objects in it. Families will be able to change the color temperature of their home to best suit their natural biological rhythms.

Nichia’s color tunable LEDs are available in the standard 757 package and chip-on-board (COB).

Nichia 2-1 Tunable White 757 LED 2700-6500K

The game changing NF2W757G-MT in the standard 757 package use a new patented technology to allow smoothly transition from warm white 2700K to cold white 6500K. The significant innovation is its ability to accomplish color tuning under a small, single light emitting surface (LES), thus achieving superb color uniformity with high color quality, up to 90 CRI. The 2-in-1 tunable white 757 enables thinner, sleeker optical designs, eliminating the need for bulky mixing chambers.

The Nichia COB 2-1 Tunable White Series are available in two sizes, 24x19mm (NVCWJ024Z-V1MT) and 19x16mm (NJCWL024Z-V1MT), and make posible to build lighting fixtures with adjustable color temperature from warm white 2700K to pure white 5000K.,Nichia's color tunable COB provides a smaller light emitting surface and better color mixing than other options on the market.
