INCADECENT LAMPS

  1. 1. High-intensity discharge lampK.A.PRAJNAY09011BB003FSP-5TH SEMJNAFAU
  2. 2. Definition:High-intensity discharge lamps (HID lamps)are a type of electrical lamp which produceslight by means of an electric arcbetween tungsten electrodes housed inside atranslucent or transparent fused quartz orfused alumina arc tube.
  3. 3. *High-intensity discharge (HID) lamps makemore visible light per unit of electric powerconsumed than fluorescent and incandescentlamps since a greater proportion of theirradiation is visible light as opposed to heat.
  4. 4. Construction:Various different types of chemistry are used in the arc tubes of HIDlamps, depending on the desired characteristics of lightintensity, correlated color temperature, color renderingindex (CRI), energy efficiency, and lifespan. *Varieties of HID lamp include:-Mercury vapor lamps-Metal halide (MH) lamps-Ceramic MH lamps-Sodium vapor lamps-Xenon short-arc lamps
  5. 5. *The light-producing element of these lamp types is a well-stabilized arc discharge contained within a refractoryenvelope arc tube with wall loading in excess of 3 W/cm². *Mercury vapor lamps were the first commercially availableHID lamps.
  6. 6. APPLICATIONS:*HID lamps are typically used when high levels of light over largeareas are required, and when energy efficiency and/or light intensityare desired. These areas include gymnasiums, large publicareas, warehouses, movie theaters, football stadiums, outdoor activityareas, roadways, parking lots, and pathways.*More recently, HID lamps have been used in small retail and evenresidential environments because of advances in reduced lumen bulbs.*HID lamps have also become common on many aircraft asreplacements for traditional landing and taxi lights.*HID lamps are also used in lamps for underwater diving
  7. 7. Benefits:Benefit #1: HID lighting creates a more natural form of light, whichresults in higher visibility.Benefit #2: HID lighting produces around three times more lightthan a traditional factory bulb.Benefit #3: HID lighting lasts much longer than tradition halogenfactory headlights, so you wont have to make numerous, frequentreplacements.Benefit #4: HID lighting is far more energy efficient.
  8. 8. Drawbacks:Drawback #1: HID lighting can be expensive. A quality systemcan cost upwards of $500.Drawback #2: HID lighting is extremely bright which can beirritating for passing vehicles.
