About Signal-Construct
Signal-Construct elektro-optische Anzeigen und Systeme GmbH is a medium-sized company with around 50 employees that develops and manufactures LED-based product solutions for a wide variety of industries. The product range extends from LED lamps and signal and indicator lights to status indicators, light guides, jumbo LEDs and LED spots through to custom LED solutions for applications in buses, trains, aircraft and ships as well as in the electrical and electronics industry, water and road engineering, and avionics. Manufacturing covers LED processing and LED taping, SMD/THT printed circuit board assembly with reflow, vapor-phase, robotic, laser and induction soldering, in-house plastic parts production on six injection molding machines, ultrasonic and spot welding, crimping, and 2- and 3-component potting technology based on PU and epoxy. Tool design and toolmaking are carried out in-house; prototypes and pilot series are realized using 3D printing and plotter technology. The in-house measuring laboratory offers a goniometer, spectrometer, optical bench and integrating sphere for light measurement as well as temperature and climate tests from -70 °C to +120 °C. Production takes place at the Niefern-Oeschelbronn site in Baden-Württemberg; manufacturing is certified to DIN EN ISO.
