Characteristics of Discharge Lamp
- Gas or Vapor Excitation: Discharge lamps operate by means of passing an electric powered modern thru a fuel, vapor, or aggregate of gases, main to the excitation of atoms or molecules.
- Emission of Light: The excited atoms or molecules emit photons, ensuing in the production of visible light as they go back to a decrease power state.
- Enclosed Glass or Quartz Envelope: Discharge lamps are housed in sealed glass or quartz envelopes, which shield the gasoline or vapor and facilitate the electrical discharge manner.
- Electrodes for Electric Arc: Electrodes inside the lamp create the electrical arc or discharge vital for stimulating the fuel and initiating the light-emitting technique.
- Ballast Regulation: Many discharge lamps require a ballast in the electric circuit to alter the modern, making sure stable operation and stopping damage to the lamp.
- Energy Efficiency: Discharge lamps are usually more strength-efficient than conventional incandescent bulbs, changing a better percent of electrical input into seen light.
- Versatility in Applications: Discharge lamps discover programs throughout a wide range of settings, which includes residential, commercial, industrial, and decorative programs, showcasing their versatility in meeting diverse lighting fixtures wishes.
What is Discharge Lamp?
Artificial light lamps using electrical discharge as a means of artificial illumination constitute an important break-through. Discharge lamps are dependable, economic and long lasting forms of lighting equipment. The operation of these lamps is based upon the movement of an electric current through a vaporous gas in a closed chamber to cause the atoms or molecules therein to flash.
For instance, the fluorescent lamp is composed of mercury vapor plus phosphor coatings encapsulated in a glass tube. When the electric current passes through, it produces ultraviolet radiation which in turn causes an electron excitation of a phosphor. Another type utilizing gas-discharge lighting for high efficiency, predominantly found outdoors or in factories and workshops is the HID (high-intensity discharge) lamp which comes across a range of different types–from metal halide to high pressure sodium lamps.
