Opportunities in Spectral Tuning from High Color Rendition to Horticulture Applications
This paper will explain how customers can utilize spectral tuning to design systems with light exactly at their desired CCT and with high color rendition. Not only can we achieve high color rendition with spectral tuning, but also we can create light that is specific to the needs of horticulture or any other applications, for that matter.
This capability of tuning light to any specific wavelength geared towards the application gives customers a powerful tool to create their desired light. Customers can create high color rendition lights as measured either using the traditional CRI or newer TM-30-15 metrics. This presentation will also review the differences between CRI and TM-30 and demonstrate how both white and color LEDs can be used to design systems with high CRI and TM-30 specifications. By showing how spectra affect CRI and TM-30 metrics, customers can decide between a solution utilizing white LEDs or a solution based on individual emitters populated on a board.
Recently, customers have migrated to high color rendition bulbs as evidenced by the increase in CRI 90+ bulbs in the ENERGY STAR Qualified Lamps Product List from 2013 to 2017. However, there are many more applications for high rendering than the residential bulb market. Shops, restaurants, hotels, supermarkets, fish markets, and indeed homes all have their own uniquely desired and optimal spectra for high color rendering.
Not only do humans need and desire various spectra. Plants also need a variety of wavelengths too. Individually designed LED solutions can be the answer, and we will discuss all these applications and suggest solutions from COBs to individual emitters to level 2 boards. In addition, to showing the flexibility in using LEDs to tune spectra content, we will also provide data that prove the long term lumen maintenance benefits of LED lighting.
