This article provides an overview of fluorescent dimming and an application circuit for low-end small fixture applications ICs where dimming levels below 10% are required and more comprehensive protection features are needed. The electronic ballast circuit.... -
The brightness of a fluorescent light bulb or neon tube cannot adjust as easily as that of a incandescent bulb because it starts only when a voltage is much higher than that of the network, then remains on at electrical network voltage. Normally, the high.... -
This 40W fluorescent lamp inverter allows you to run 40W fluorescent tubes from any 12V source capable of delivering 3A. This is basically a larger version of the 12VDC Fluorescent Lamp Driver and can be used to light regular or blacklight tubes. # Wind.... -
This circuit came from a 14 Watt Commercial Electric spiral bulb from Home Depot. In fact, I drew it in that way because it was layed out very well, so much credit should go to Sam Goldwasser. It is a rather interesting oscillator circuit which I will.... -
Even if a fluorescent tube it`s not a neon glow lamp and this page it`s not maybe at the right place, this circuit is very interesting because it uses an odd way to power a very common lamp. Like glow lamps, neon tubes are composed by two electrodes in a low.... -
This inverter will drive any fluorescent lamp between 8w and 20w but works best with 16w tubes. It preheats the electrodes and keeps them heated while.... -

Compact fluorescent lamps have some benefits in comparison with classic light bulbs. It is lower power consumption (to 80%) and much longer lifetime (5 to 15 times). Disadvantages are longer starts mainly at more expensive types, impossibility to use darker.... -
Dimming function opens up a completely new family of CFL applications Compact fluorescent lamps (CFLs) are replacing incandescent light bulbs at a rapid rate due to their.... -
This little project arose from a desire to experiment with some of the more "traditional" methods of radioconstruction which enjoyed popularity some 70 years ago. I wanted to find out for myself what kind of performance could be achieved using simple.... -
Whenever there is a need for battery-powered lighting, like for camping, solar powered cottages, cars, boats, planes, or emergency purposes, fluorescent lamps have a great appeal. Firstly, they are very much more efficient than glow lamps, so they produce.... -
Fluorescent tube is connected in the LC resonant circuit composed of L2 and C9. Bidirectional breakdown diode VD4 is starting circuit. When AC power is connected, VT2 gate potential increases by VD4; when the voltage exceeds the gate threshold voltage, VT2.... -
IR2156 can offer solution of high cost-effectiveness for fluorescent electron ballast. It can integrate lighting tube error protection and the programmable working frequency with warm-up, lighting and ballast continue working... -
The fluorescent lamp electronic ballast circuit is composed of the rectifier filter circuit, high-frequency oscillator circuit and output circuit, and it is shown in Figure 3-202. Rectifier filter circuitis composed of the rectifier diodes VDl-VD4 and filter.... -
Four-wire ballast connection of fluorescent There are four lead wires in four-wire ballast, including main and auxiliary coils. The connection of two lead wires in main coil is the same with second-line ballast, both of them connect between the lamp and.... -
General connection method of fluorescent lamp Fluorescent lamps used in homes and public places lighting and so on, with luminous efficiency, long service life, Figure 20 is the general wiring diagram for lamp. Fluorescent working principle: When the switch.... -
Homemade 20W fluorescent lamp dimmer Using the method of connecting capacitor in series can easily control the brightness of fluorescent lamps. To adapt to different lighting requirements. Figure 28 is a modified circuit diagram. When the switch connects to....
