Title: LED APPARATUS EMPLOYING NEODYMIUM BASED MATERIALS WITH VARIABLE CONTENT OF FLUORINE AND OXYGEN
Abstract:
An apparatus such as a lighting apparatus (110A, 110B, 110C, 110D) comprises at least one LED (or OLED) module (115), 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 (110A, 110B, 110C, 110D) 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 NdF xO y compound with values of x and y determining a content ratio F/O, which may be adjusted during manufacturing of the NdF xO y 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 NdF xO y compound.
