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 optical component comprising a compound consisting essentially of the elements neodymium (Nd) and fluorine (F), and optionally including one or more other elements. The lighting apparatus is configured to provide a desired light spectrum by filtering the generated visible light using the compound. The at least one component can comprise a NdFxOy compound with values of x and y determining a content ratio F/O, which may be adjusted during manufacturing of the NdFxOy compound to provide desired output light parameters of the apparatus including at least a desired output light spectrum realized by filtering the generated visible light using the NdFxOy compound.
