[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 99, N° 4/2009 (04/2009) . - p. 59-62 Titre : All systems go for white light Type de document : texte imprimé Auteurs : Martin Döbler, Auteur ; Christoph Klinkenberg, Auteur ; Rainer Protte, Auteur Année de publication : 2009 Article en page(s) : p. 59-62 Langues : Anglais (eng) Index. décimale : 668.4 Plastiques, vinyles Résumé : LED optics - Polycarbonate with its optical, mechanical and technical properties is ideally suited for the manufacture of light guides and optical lenses for LEDs. For this reason grades have been tailor-made to provide very high transmission and extreme resistance to the white light from high-performance LEDs. Using a new cost-effective production concept developed at the same time, complex LED optics with large step changes in wall thicknesses can now be manufactured with high precision.
