This ensures the remaining string of LEDs will continue to function. There are many cases where high reliability of the LED lighting must be maintained, such as LCD backlighting, transport lighting, avionics, intrinsically safe and low maintenance lighting.

Note: The interaction between the Bourns(R) LSP device and the power supply for the LED series string dictates the power supply architecture. Proper care must be taken in the design of the power supply architecture to ensure that the Bourns(R) LSP devices operate as intended and the design maintains integrity.
