Description
- DN05013/D, Design Note is to build a LED retrofit using a T5 fluorescent tube fixture. A constant current regulator, NSI45090JDT4G, is incorporated, and the whole circuit exceeds ENERGY STAR power factor rating greater than 0.7. The circuit consists of a bridge rectifier using MURA160T3-D, a constant current regulator (CCR), an adjusting resistor, LEDs (Xlamp ML-E), and GE T5 23 fixture. At the input, an overload fuse can be added to protect the circuit from current spikes. The design consists of two circuit boards, one for the CCR (90mm x 18mm) and one for the LED's (516mm x 18mm). The CCR board has 6 parts on it, 4 bridge diodes MURA160T3-D, 1 CCR NSI45090JDT4G, and 1 resistor of 2.5-Ohm. The LED board has 42 LEDs, 4 resistors of 1-Ohm, 4 Tyco pins, and a (250mA/125V) fuse
