   |
This is a 28 VDC (aircraft) LED overhead reading light using three Cree XR-E 1-watt LEDs. It is externally dimmable using a 25 KHZ PWM input. It is built on Bergquist metal core material board to insure good thermal conductivity. It features the new National Semiconductor LMZ14201 ultra low noise switching regulator to meet tight aircraft EMI standards. |
