This document describes a 3-fold advertising display with a spherical radiating surface of 3mm diameter. It is made of PC material and has good heat resistance and ESD protection. The display is used in conjunction with SMD LEDs and can achieve mixed color displays.
The Lender 1276.1003 L1‑L12 is a light‑guide component designed for use with SMD LEDs. It features a 3‑fold display and a spherical radiating surface of Ø3 mm, allowing mixed‑color illumination while preventing excess light spill with an integrated screen.
Technical specifications include material details, environmental limits, and protection ratings. The component is mounted on a printed board via two press‑in lugs, with a 3.8 mm spacing between adjacent light guides. Recommended LEDs and layout suggestions are provided in the accompanying pages. This manual is written in German.
