CIRCUIT PROTECTION PRODUCTS ADVANCE NOTICE 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 configured with long strings of multiple series LEDs driven from a relatively high voltage compliance, constant current power supply. In that configuration 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 LED lighting applications, high power LEDs would require very large and expensive zener diodes. Placing the Bourns(R) LSP device across LEDs allows the remaining LEDs in a series string to continue to work when an LED fails open circuit.
