  2. Content • Lamp history • Lamp types • Common lamp & compare • How to change the lamp • Conclusion • References

  3. A. Lamp history In 1802 HumphryDavy invented the incandescent lamp of a current through the platinum, the disadvantage is not bright enough, and the duration is too short. In 1835 James BaomanLinRace showing constant electric light, but no further development. In 1840 Warren de la Rueplatinumas a concept, although the final improve life, but the cost is too high.

  4. In 1841 Frederick in England with the first platinum wire incandescent patents. In 1845 John Starr uses made of carbon fiber incandescent lamp, but after death that got patented. In 1851 Robert-Houdinpublicly display his incandescent lamp in France. In 1872 Alexander invented incandescent lamp was got theRussian patent in 2 years after.

  5. In 1878 Thomas Edisoninventedthe first practical incandescent lamp. ↑ Thomas Edison improved the bulb ↑Thomas Edison

  6. In 1990 Carl Orrinvention a tinsel incandescent lamp. In 1904 Zander and Franjo be granted to Hungarian patent, which is the first tungsten filament bulb.

  7. B. Lamp types (1)Incandescent type： Bulb、Halogen bulbs、Seal spotlight lamp (2) fluorescent light ： Energy-Saving Lamps、Fluorescent tubes、and so (3) Gas discharge lamp： Mercury lamps、Neon light、and so

  8. (4) Arc： Arc lamp、Mercury arc lamp、Xenon lamp (5) Combustion： Calcium carbide lamp、Candle、Gaslight、Kerosene lamps、Lime light、Oil lamps、Safelight、Kerosene vapor lamps、Lantern、Torch (6) Other： LED lights、Optical fiber、Plasma lamp、Chemiluminescence 、Electroluminescent fiber strand

  9. C. Common lamp & compare Commonly used lamp： (1) Bulb： Standard name for the incandescent ,use the tungsten filament heated to incandescence to light.

  10. (3)Seal spotlight lamp： The use of tungsten to emit light, and shed light gathered together, to strengthen the intensity of the lamp. (2)Halogen bulbs ： Use of iodine or bromine, be the filled with gas,when the tungsten atoms evaporated to 800 ° C and iodine, bromine do combine to emit light.

  11. (5)Fluorescent tubes ： Use of electricity to stimulate the mercury vapor in argon or neon gas, a plasma is formed and issued short-wave UV, UV absorption of phosphorus, phosphorus emits visible light illumination. (4)Energy-Saving Lamps ： Trace mercury with to make a light bulb.

  12. (7)Neon light ： The use of high-temperature tube (arc tube) within a stable arc discharger and more than 3 W / cm ² of light-emitting power. (6)mercury lamps ： Also known as mercury lamps, divided into low-pressure, high-pressure, high pressure three types, uses a wide range, can be used in the lighting around the corner or sterilization.

  13. (9)Optical fiber： Utilization a refractive mannerto be conducted, can be used to transfer signals. (8)LED lights： Also known as light-emitting diodes, trivalent and pentavalent element composite light source.

  14. D. How to change the lamp

  15. E. Conclusion In today's society, changing light bulbs, lamp has the necessary skills, if you know how to do-it-yourself change, so long as there is material received can save a people exchange costs, but do-it-yourself conversion drawback isthey have to pay attention to safety, we have to be careful in order to save money and convenient.
