The document describes the features and characteristics of LS A67F, LR A67F, LA A67F, LO A67F, LY A67F SIDELED® Enhanced Thinfilm LED, including their applications, optical parameters, processing methods, etc.
The LS A67F series includes the LS, LR, LA, LO and LY variants, each offering side‑emitting light suitable for coupling into light guides. The LEDs are supplied in a white SMT package with a colorless clear resin and feature parallel radiation to the PCB.
Key specifications cover wavelength ranges from 590 nm (yellow) to 633 nm (super‑red), a Lambertian viewing angle of 120°, and optical efficiencies up to 70 Im/W. The devices are RoHS‑compliant, ESD‑protected up to 2 kV, and designed for standard SMT assembly processes. This manual is written in German.
