Conclusion

ReferencesA. Lamp historyIn 1802Humphry Davy invented the incandescent lamp of a current through the platinum, the disadvantage is not bright enough, and the duration is too short.

In 1835James Baoman LinRace showing constant electric light, but no further development.

In 1840Warren de la Ruep latinum as a concept, although the final improve life, but the cost is too high.In 1841Frederick in England with the first platinum wire incandescent patents.

In 1845John Starr uses made of carbon fiber incandescent lamp, but after death that got patented.

In 1851Robert-Houdin publicly display his incandescent lamp in France.

In 1872Alexander invented incandescent lamp was got the Russian patent in 2 years after.In 1878Thomas Edison invented the first practical incandescent lamp.

Thomas Edison Thomas Edison improved the bulbIn 1990Carl Orr invention a tinsel incandescent lamp.

In 1904 Zander and Franjo be granted to Hungarian patent, which is the first tungsten filament bulb.

C. Common lamp & compareCommonly used lamp

(1) BulbStandard name for the incandescent ,use the tungsten filament heated to incandescence to light.

(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.

(3) Seal spotlight lampThe use of tungsten to emit light, and shed light gathered together, to strengthen the intensity of the lamp.

(4) Energy-Saving Lamps Trace mercury with to make a light bulb.(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.

(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.(7) Neon light The use of high-temperature tube (arc tube) within a stable arc discharger and more than 3 W / cm of light-emitting power.

(8) LED lightsAlso known as light-emitting diodes, trivalent and pentavalent element composite light source.(9) Optical fiberUtilization a refractive manner to be conducted, can be used to transfer signals.

D. How to change the lamp

E. ConclusionIn 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.F.
