Abstract

See full text

In one embodiment, a light emitting device includes a lighting element located in a housing, wherein the housing is formed from a plastic composition including, for example, a polycarbonate formed from reacting, in the presence of a transesterification catalyst, a diaryl carbonate ester and a bisphenol A, wherein the bisphenol A has a sulfur concentration of 1 ppm to 15 ppm, based upon a weight of the bisphenol A; and a conversion material wherein the conversion material includes an inorganic material that converts radiation of a certain wavelength and re-emits of a different wavelength; wherein after the conversion material has been exposed to an excitation source, the conversion material has a luminescence lifetime of less than 10−4 seconds when the excitation source is removed.
