The most common fluorescent lamp is the hot cathode: Parts: This lamp consists of a glass tube filled with an inert gas (usually argon) at low pressure. A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour. On each side of the tube you will find a tungsten electrode. The ballast regulates AC power to the electrodes.

Animation shows the circuit of the first kind of fluorescent lamp called the preheat. See how the ballast and starting switch work to strike an arc in the la.

In most fluorescent lamp s, a mixture of argon and mercury gas contained in a glass bulb is stimulated by an electric current, producing ultraviolet rays.

An electric lamp that produces light through fluorescence. Define fluorescent lamp. English dictionary definition of fluorescent lamp. The 12V drivers for fluorescent lamps are tricky, because of the compromise between a good operating efficiency and the ability to start the lamp.

The demands are in contradiction. Here are starting methods: 1. Pure flyback single-transistor inverter, makes voltage spikes in the kilovolt range in idling condition, so that the lamp will start. The classic fluorescent lamp design, which has fallen mostly by the wayside, used a special starter switch mechanism to light up the tube. You can see how this system works in the diagram below.

When the lamp first turns on, the path of least resistance is through the bypass circuit, and across the starter switch. Well Curate Well Designed. Your Space Has Never Looked Better.

Traditionally it had been believed that to achieve good colour rendering, it was important for the lamp to produce a full spectrum with light of all wavelengths present.

No one knows who initially proposed the notion that Agapito Flores, a Filipino electrician who lived and worked in the early 20th century, invented the first fluorescent lamp.

In spite of evidence that disproves the claim, the controversy has raged for years. Some proponents of the tale have gone so far as to suggest that the word " fluorescent " was. The crushed glass is compacted into 55-gallon containers.

This light then causes a phosphor to fluoresce, producing visible light. There are two general types, traditional fluorescent and compact fluorescent. This article is about traditional (straight tube shaped) fluorescent lamps. Check out our fluorescent lamp selection for the very best in unique or custom, handmade pieces from our lamps shops.

Introduction to fluorescent lamps: How it works, inventors, animations. The fluorescent light is the most prolific type of lamp in the world. Mercury-vapor gas discharge lamps are an artificial light source that generates light by sending an electrical discharge through an ionized gas.

Electric current is passed though the lamp to excite the gas into producing ultraviolet (UV) light that is invisible to the eye. The UV light then causes the coating on the inside of the tube to glow, emitting visible light. The flexibility of fluorescent technology lends itself well to the generation of light colours other than white. A full range of coloured tubes exists, as well as certain ultra-violet versions.

These have diverse applications such as sun tanning, photocopying, medical treatments, detection of forged bank notes, identification of minerals, entertainment lighting etc. Fluorescent tube lights are filled with a mercury-vapor gas. HID lamps (mercury-vapor, metal-halide and high-pressure sodium) are used for street lights, floodlights and industrial lighting. Lamps in both of thses categories can contain mercury and thus most be properly managed.

What type of lamp are you using? Because they go with the most common fluorescent lamp types, chances are you will need an F32Tballast, F40Tballast, or F54Tballast, but your lamp may be different and require a different light ballast.

Determine what that lamp type is before you go any further.
