New LED Street Lamps from Fairchild Semiconductor

Fairchild Semiconductor announced that its GPRC (Global Power Resource Center) in China has developed a new LED street-lighting solution for meeting the green-electronics demand. The LED solution offers low power consumption, high thermal performance, and high efficiency, thereby improving the street lamps’ lifetime.

LED Lighting Solution

The LED lamp includes a constant current control, DC-DC control, and a CrCM (critical conduction mode) PFC.  The lighting solution comprises either serial or parallel sub-solution in a single PCB layout. The serial and parallel sub-solutions deliver efficiencies of up to 92.6% and 91.26%, respectively, under an input voltage of 220V, from the AC input to the side of LED.

The serial solution features an open circuit-protection, while the parallel solution features an independent current regulation, for every single LED string. This function allows both the sub-solutions to operate normally even when a LED string malfunctions due to an open circuit. When a short circuit occurs in an LED solution, the constant current circuits makes sure that normal functioning occurs in the remaining LEDs in the series and parallel sub-solutions.
