This document describes the features and characteristics of LR W5SM, LA W5SM, LY W5SM Golden DRAGON® Enhanced thin film LED Lead (Pb) Free Product - RoHS Compliant, including its Gehäusetyp, Typischer Lichtfluss, Besonderheit des Bauteils, Wellenlänge, Abstrahlwinkel, Technologie, optischer Wirkungsgrad, etc.
The OSRAM W5SM series comprises three colour variants – red (LR), amber (LA) and yellow (LY) – in a white SMD package with a clear silicone resin. The LEDs are thin‑film InGaAlP devices offering high luminous efficiency in a compact form factor.
The document provides ordering information, maximum ratings, electrical and optical characteristics, wavelength and brightness group definitions, as well as safety and packaging notes. It is intended for designers and distributors needing detailed specifications for integration into traffic signaling, automotive lighting, backlighting and decorative applications. This manual is written in German.
