With the full spectrum of sunlight
The latest innovation in LED development is called NF2W757GT-F1 Optisolis. The full-spectrum LED from world market leader Nichia is capable of generating a light spectrum that comes closest to that of the sun. This is achieved by a revolutionary new phosphor technology and a special blue LED chip. The spectrum of the 420nm chip contains almost no UV emissions and in combination with the phosphor achieves a CRI value of almost 100.
A main application to Optisolis application is Human Centric Lighting - a special type of lighting that adapts to the human inner clock and thus to the biorhythm. In addition, Optisolis can be used wherever an extremely high CRI is required, e.g. in operating theatres in hospitals.
Manufacturers can utilize Optisolis™ and trust in a spectrum where all colors are reproduced to the color seen under a standard light. (Figure 1) Also, color rendering index has been significantly improved compared with the current products for general lighting. (Figure 2) Most importantly, since UV emission is essentially non-existent in the spectrum, the degradation of irradiated materials can be reduced dramatically compared to that of other light sources containing UV emission, including other market available LEDs.
Target applications include Museum and Art Gallery Lighting, where the highest CRI is preferred, but UV radiation and light sources can be detrimental. Additional applications could include Color Evaluation（e.g. painting, printing), Commercial Lighting (e.g. retail, etc.) or anywhere Ultra-High CRI is desired.
The Optisolis family consists of two series, the NF2W757G-F1 and NF2L757G-F1. Both series are housed in a 3 x 3 x 0.65mm package.
