Shunt SMD - LSP series
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. This configuration has several benefits:
Multiple LEDs can be arranged in series to simplify the power supply design.
High voltage, low current power supply improves efficiency of the power supply.
Modular design can allow easy scaling; for example, using 1 W LEDs - 8 W, 16 W, 24 W or 32 W designs can easily be created with multiple strings of 8 x 1 W LEDs.
One LED streetlight design uses six strings of 15 LEDs for a total of 90 LEDs.
