Abstract
The specification and drawings present a new apparatus such as a lighting apparatus, the apparatus comprising at least one LED (or OLED) module configured to generate a visible light such as white light, and at least one component such as an optical component comprising multiple (two or more) compounds, each containing neodymium (Nd) and at least one compound including fluorine (F) for imparting a desired color filtering effect to provide a desired light spectrum, where a color of the desired light spectrum in a color space is determined by relative amounts of the two or more compounds in the at least one component.
