EucoLight study develops technical method for automated type detection within lamp waste streams

The study focused on the separation of collected End-of-Life lamps, to separate conventional gas discharge lamps (GDLs) from light-emitting diode (LED) lamps.

The project commenced with a theoretical phase in which technological options for sorting methods were explored and described. Based on this analysis, a testing phase followed, concentrating on static and dynamic testing with three promising sorting technologies.

Ultimately two methods, using blue light and electromagnetic induction were considered promising and taken forward. The test results showed that electromagnetic induction successfully detected 100% of non-broken GDLs. Broken GDLs are not detected using this approach, since the gas needed to respond to the field has been lost.
