Abstract (en)
[origin: WO2019020478A1] The invention relates to LED lighting elements comprising translucent molded parts made of polycarbonate-based molding compounds containing a coloring agent mixture, carbon black, scattering additive and, optionally, white pigment, said molded parts being used as covers having a daytime/nighttime design, for example. A combination of the molded parts with one or more RGB LEDs results in surprising color effects in the nighttime design and a deep gloss effect of grey or black molded parts in the daytime design.
