Bourns Releases New LSP (Open LED Shunt Protector) Products
Riverside, California - TO BE RELEASED JANUARY 23, 2012 - 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 con gured with long strings of
multiple series LEDs driven from a relatively high voltage compliance, constant current
power supply. In that con guration an open LED will cause a complete LED string to go
dark, rendering the application useless or markedly compromised.  is can lead to
warranty returns or maintenance calls.
While low power LED string designs may have used zener diodes in LED lighting applications, 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.
