Farnell have recently introduced the latest technology Littelfuse PLED5 series
This family provides three methods of increasing the relaibility of LED lighting:
- If one LED in an array fails open, the PLED device provides an electronic path so the array continues to function.
- The PLED device provides protection from ESD events up to 8KV for contact discharges and 15KV for air discharges.
- Protection is provided in case of accidental reverse battery or power connection.
High reliability of lighting functions such as traffic lighting, aircraft lighting, advertising lighting and runway lighting demand the use of a device such as the PLEDs.
