Description

field of invention

[0001] The present invention relates to a polymer composition comprising at least one polyester, at least one hindered amine compound and at least one trivalent phosphorus compound selected from the group consisting of Various components: phosphites, phosphonites and mixtures thereof.

[0002] The invention further provides an article, such as part of a light emitting diode (LED) device, comprising a composition of the invention. Background of the invention

[0003] LEDs are increasingly used as light sources in a large number of applications due to their many advantages over traditional light sources. LEDs generally consume considerably less power than incandescent and other light sources, require a low operating voltage and are resistant to mechanical shocks. As such, they are replacing incandescent and other light sources in many applications and have been used in such diverse fields as traffic signals, interior and exterior lighting, cell phone displ...
