Abstract:
Disclosed herein is a light emitting device, comprising: a lighting element located in a housing, wherein the housing is formed from a plastic composition comprising: a conversion material, and a polycarbonate composition comprising: a flame retardant comprising a sulfonate salt and three polycarbonates. The first polycarbonate has a branching level of greater than or equal to 2%, a weight average molecular weight of 20,000 g/mole to 55,000 g/mole and a peak melt viscosity of greater than or equal to 25,000 poise. The second polycarbonate has a glass transition temperature greater than or equal to 170° C. The third polycarbonate has a branching level of 0 to less than 2% and a molecular weight of 17,000 to 40,000 g/mol.
