Gas Discharge Phenomenon in Electrical Gas Discharge Lamps

Gas discharge phenomenon is an essential characteristic of gas discharge lamps used in various lighting applications. When electric power is applied across the electrodes present inside a discharge tube, the electrodes give out electrons which bombard with the gas atoms introduced inside the discharge tube. Due to these collisions, a considerable part of the applied … Read more

Low Pressure Sodium Vapour Lamp

Low-pressure sodium vapor lamp is termed as a “miscellaneous discharge lamp” as it possesses some characteristics of High Intensity Discharge (HID) lamps as well as it resembles fluorescent lamps in other areas. Basically, LPSV lamp is a gas discharge lamp that uses sodium in an excited state to produce light. A typical LPSV lamp is … Read more

Electric Lamp | Types of Electric Lamp

An electric lamp is a conventional light emitting component used in different circuits, mainly for lighting and indicating purposes. The construction of lamp is quite simple, it has one filament surrounding which, a transparent glass made spherical cover is provided. The filament of the lamp is mainly made of tungsten as it has high melting … Read more

Materials Used in Lamp Bulb

Various types of material are used to build a lamp. Insulating materials, conducting materials are the essential parts of a lamp set up. The details of those materials are given below. Glass As it is a transparent material, used as barrier. Light gets various colors depending on the color of the glass. It with stand … Read more

Tungsten Halogen Lamps

In 1958, E.G. Fridrich and E.H. Wiley had has developed Tungsten Halogen Lamp by introducing a halogen gas (basically Iodine) inside the incandescent lamp. Basically, without halogen gas, incandescent lamp filament gradually losses its performance because of its filament evaporation at higher temperature of operation. The evaporated tungsten from the filament of normal incandescent lamp … Read more

Incandescent Lamp Principle and Construction of Incandescent Lamp

The electrical light source which works on the principle of incandescent phenomenon is called Incandescent Lamp. In other words, the lamp working due to glowing of the filament caused by electric current through it, is called incandescent lamp. How do Incandescent Lamps Work? When an object is made hot, the atoms inside the object become … Read more

Metal Halide Lamps

What is Metal Halide Lamp? Metal halide lamp is special type of arc discharge lamp that works on the arc stream via some iodide salts along with argon gas and mercury vapor pressure at several millimeters with the arc tube temperature of 1000 K. Who Invented Metal Halide Lamp? Dr. Reiling had discovered Metal Halide … Read more

High Pressure Sodium Lamps or HPS Lamps

High-pressure sodium lamps (also known as HPS Lamps or HPS lights) are a type of sodium lamp that is widely used in industrial lighting and many public outdoor areas. They are commonly used in public parking lots, roadways, and other security areas. A big driver behind their use is their high efficiency – around 100 … Read more

Xenon Arc Lamp

A xenon arc lamp is a special type of gas discharge lamp. Xenon arc lamp’s produce light by passing electricity through ionized xenon gas at a high pressure. It produces a bright white light that closely mimics natural sunlight, which extends its applications into the film, and daylight simulation industries. Xenon Arc Lamp Construction The … Read more
