Bourns Releases New LSP (Open LED Shunt Protector) Products
Riverside, California - January 20, 2011 - Bourns is pleased to announce the release of LED Shunt Protector
products for the LED lighting market. In LED lighting applications, solid-state lighting luminaires are
commonly confi gured with long strings of multiple series LEDs driven from a relatively high voltage
compliance, constant current power supply. In that confi guration an open LED will cause a complete LED
string to go dark, rendering the application useless or markedly compromised. This can lead to warranty
returns or maintenance calls.
While low power LED string designs may have used zener diodes in this confi guration, high power LEDs
would require very large and expensive zener diodes. Placing the Bourns® LSP device across LEDs allows the
remaining LEDs in a series string to continue to work when an LED fails open circuit.
