Abstract
In one embodiment, a device can comprise: a light emitting diode located in a housing. The housing is formed from a polymer composition comprising: a polymer material, wherein the polymer material comprises at least one of polyolefins, polyesters, cyanoacrylate, cellulose triacetate, ethyl vinyl acetate, propyl vinyl acetate, polyvinylbutyral, polyvinyl chloride, polycarbonate, polyethylene naphthalate, polyurethane, thermoplastic polyurethane, polyamide, polymethyl methacrylate, polystyrene, cellulose nitrate, and combinations comprising at least one of the foregoing polymer materials; and a coated conversion material wherein the coated conversion material comprises an inorganic material that converts radiation of a certain wavelength and re-emits of a different wavelength. The coated conversion material can have a coating comprising at least one of a silicone oil and amorphous silica and, after the coated conversion material has been exposed to an excitation source, it can have a luminescence lifetime of less than 10seconds when the excitation source is removed.
