Nichia has recently announced a joint product development venture with solid-state lighting (SSL) manufacturer Zumtobel based around Nichia’s Optisolis and Vitasolis human-centric lighting LEDs, according to LEDs Magazine. Aimed at delivering cost-effective lighting fixtures with direct applicability to health and wellness, the partnership will see the aforementioned LEDs being incorporated into the Light Fields III and Ondaria fixture. Each product will also come pre-equipped with the Zumtobel Spectrum light-design engine, which will be incorporated into more models in Zumtobel’s portfolio moving forward.
The Vitasolis Approach
What sets these HCL solutions apart from the rest is the approach Nichia has taken in designing the Vitasolis LEDs. The LED only focuses on the daytime spectrum for the purposes of creating more energizing lighting. That spectrum is then delivered with higher than average cyan levels, thanks to a phosphor-converted white LED, instead of traditional cyan emitters used in most LEDs.
The result is a more cost-effective HCL LED that can help drive greater adoption of lighting for health and wellness installations. In addition, the design offers moderate color rendering performance. Meanwehile, the Optisolis, following in similar footsteps, can deliver near 100 levels of color rendering for the aggregate metric and all 16 color samples. The company has even claimed that the LED tops the industry for mimicking the spectral power distribution (SPD) of the sun.
With the Zumtobel Spectrum light-design system at its back, the Optisolis LED delivers both the warm red energy of the sun that helps prepare a person for rest, while also being able to deliver superb light quality through the minimization of shorter wavelength light. Together, the pairing also eliminates any emission of light on the ultraviolet (UV) spectrum where other lights often use violet emitters to achieve their SPD. This, according to Nichia, allows the lights to have exceptional capabilities in art museums, where even the smallest amount of UV LED energy could potentially damage works of art over long enough periods of exposure.
