Lamps

Description

Lamps produce artificial light and are replaceable electrical components, which use electricity to create a lighting atmosphere. Usually, lamps consist of a base of metal, plastic, glass, or ceramic, with an electrical connection with a light fixture. Light fixtures are electrical devices used for creating artificial illumination. A wide range of light fixtures is produced for use in aerospace, medicine, marine, and automotive industries.

Lamps are classified as follows:

• Fuel lamps which are further categorized as:
  • Betty lamps
  • Butter lamps
  • Carbide lamps
  • Kerosene lamps
  • Candle lamps
  • Oil lamps
• Arc lamps which are further categorized as:
  • Davy lamps
  • Geordie lamps
  • Xenon arc lamps
• Incandescent lamps which are further categorized as:
  • Carbon button lamps
  • Lava lamps
  • Nernst lamps
• Fluorescent lamps which are further categorized as:
  • Linear fluorescent lamps
  • Compact Fluorescent lamps (CFL)

Advantages

The advantages of lamps are as follows:

• Fluorescent lamps, especially CFLs, are five times more energy efficient than incandescent lamps
• Fluorescent lamps help save nearly 7 billion kilowatt hours of power each year
• Fluorescent lamps help reduce air pollutants like carbon monoxides, nitrogen oxides and sulfur oxides annually
• LED lamps have an operational life of nearly 100,000 hours, which is equal to 11 years of nonstop operation

Applications

• Oil lamps are used to create a particular lighting atmosphere
• Other than domestic usage, lamps have a wide range of applications such as their usage in audio-visual projectors, video camera lights, photocopiers, stage systems, studio systems, fiber-optical systems, airport runway markers, scientific and medical instruments
