A dielectric mirror substrate having a wavelength selective reflectance is configured to reflect ultraviolet wavelengths, and to pass blue and longer wavelengths. The portion of the ultraviolet light that is not absorbed in the quantum dot layer is reflected rather than transmitted, where it has another chance to be absorbed in the quantum dot layer, thereby increasing the overall conversion efficiency. The increased energy associated with the ultraviolet light further results in greater conversion efficiency in the quantum dot layer. The ultraviolet and blue LEDs may be driven by an electronic circuit that varies the amount of power applied to each LED to control the brightness and color balance of the generated white light."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Quantum dot tunable assemblies and methods","description":"A tunable light generating assembly uses ultraviolet and blue light emitting diodes to pump red and green quantum dots in a quantum dot layer to generate white light.
