12V Flourescent Lamp Inverter

Fluorescent tubes use a methods much less vitality than incandescent lamps and fluorescent tubes final a perfect deal lengthyer as neatly. Other benefits are diffuse, glare-free lighting and low heat output. For these motives, fluorescent lights is the natural possibility in commercial and retail buildings, workshops and factories. For battery-powered lights, fluorescent milds are additionally the primary choice because of their excessive effectivity. The main drawback with running fluorescent lights from battery power is that an inverter is required to drive the tubes.

12V Fluorescent Lamp Inverter Circuit Diagram

Fig.1: two switch-mode circuits are concerned here: the DC-DC inverter involving IC1, Q1 & Q2 and the fluoro tube powerr which converts excessive voltage DC to AC by the use of IC3 and Q3 & Q4 in a totem-pole circuit.

Inverter efficiency then transforms the key issue. There are many industrial 12V-operated fluorescent lamps available which use 15W and 20W tubes. However, it is uncommon to look one which drives them to full brilliance. For example, a typical commercial twin 20W fluorescent lamp working from 12V draws 980mA or 11.8W. Ignoring losses in the fluorescent tube pressurer itself, it means that every tube is simplest equipped with 5.9W of power which is considerably not up to their 20W rating. So whereas the lamps do use 20W tubes, the gentle output is smartly below par.

Warning:

This circuit generates in excess of 300V DC which can be lethal. Construction will have to only be attempted via these experimenced with mains-level voltages and safety processs.
