Each of the wavelength-converting materials is configured to produce a visible light from a narrow band light near UV region produced by the light-emitting dies, but with different correlated color temperatures (CCT) and different spectral contents. The combination of the two visible light forms the desired visible white light. The Color rendering index of the light-emitting device is tunable by adjusting the supply current to the light-emitting dies. In another embodiment, a light module with tunable CRI for an illumination system is disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light source with tunable CRI","description":"A light-emitting device with at least two light-emitting dies encapsulated with two different types of the wavelength-converting materials is disclosed.
