Bourns, a manufacturer and supplier of electronic components, has unveiled a new line of open LED shunt protection devices designed specifically for LED lighting applications. Designated the Bourns LSP-Series, the new shunt protector family enables LED lighting applications configured in strings to be more robust and reliable.
At present most LED designs include solid-state lighting luminaries configured in series strings of 20 or more LEDs. In this configuration, an open LED can cause the entire LED string to go dark, resulting in reduced performance and possible maintenance calls and costly warranty returns. According to Bourns by adding the LSP-Series shunt protector to an LED design the unaffected lights in the string will remain illuminated by shunting current around the inoperable LED. The new LSP-Series of open LED shunt protectors are an optimal solution for a variety of LED lighting applications including light bulbs, lighting fixtures and backlighting systems. “LED lighting applications are exploding in volume,” said Ian Doyle, product line manager of semiconductor products at Bourns. “This new LSP-Series of open LED shunt protectors address the failure rates of early LED designs.” The LSP-Series of open LED shunt protectors include four models: LSP0600BJR-S, LSP0900BJR-S, LSP1300BJR-S and LSP1800BJR-S. The new device family comes in an SMB surface mount package and is RoHS compliant.
