Fast Production Test of UV-LEDs
Numerous applications, for example in the medical area or in material testing, are based on precisely specified UV radiation. For UV-B and UV-C emitters, the measurement of their spectrum between 325 nm down to 200 nm is generally only possible with extended measurement times due to their low radiant flux. As such, a condition for fast testing within production is high reliability in conjunction with high optical throughput of all participating system components. Within its well-established CAS-series of premium spectroradiometers over many years, Instrument Systems has developed a novel series-type CAS 140D-157. This new system measures precisely and reliably not only within the visible spectrum, but also in the UV. Coupled with a PTFE-coated integrating sphere, the system permits for fast 24/7 production tests of UV emitters to be run.

Inventronics Expands EBS Product Line with DALI Compatibility and Advanced Common Mode Surge Protection
Inventronics has announced the release of the new EBS BTE Series of 40 W, constant-current programmable IP20 LED drivers. They operate from 176-305 Vac input and are designed for operation in both Class I and Class II environments. They are primarily aimed at street lighting applications but are equally capable in any luminaire where robust performance is needed. The advanced common mode surge protection fully meets EN61000-4-5 and EN61547, even in Class II luminaries, thus providing market leading protection against common mode surge; the most frequent cause of failure in street lighting.
