A lamp is a device that produces light. The word "light" can also mean a light bulb. The lamp was first discovered by Sir Joseph William Swan. Lamp is an object that serves as a light, the lamp has a shape like a bottle with ronga a small wire bearing that will be misleading when connected to the flow of electricity.
Early presence of light from a scientist who is considered stupid though considered stupid and often failed but this person did not give up in experiments to create lights after years of scientists also created a light bulb. The scientist who invented or could be called the creator of a light bulb is Thomas Alfa Edison. The long struggle made by Thomas is now getting results, which used to always fail now his invention almost everyone uses it.
The types of lamps

1. Halogen Lamp
   This lamp uses wire and tungsten material and in its vacuum chamber is supplied with gas. Mi gas has the function of creating strong rays. Halogen lights are used as spotlights.The halogen lamp usually has a reflector (mirror behind it) to amplify the outgoing light. The fittings are usually special, but currently there are also with the usual fitting type.
   This type of lamp is a good spot light. Spot lights are the lights the light leads to one area only, for example the light to illuminate the art object in a focused manner. These lights are good for use as garden lighting to make a dramatic impression of centralized lighting such as illuminating sculptures, plants, ponds or other areas. This type of lamp is actually a filament lamp that has been successfully developed to be brighter, but also the needs of energy (watts) are relatively the same.
2. Incandescent Lamp
   This type of lamp is incandescent in its filament wire when the flow of electricity runs through it. This wire emission is turned into light.This type of lamp is very easy to burn but very hot for long wear. Therefore. This type of lamp is wasteful of energy. The color of incandescent light is yellow and the color temperature is 2 "500 - 2" 700 K (Kelvin) This type of light developed by Thomas Alfa Edison uses a tungsten filament that is a kind of incandescent wire inside a glass ball filled with nitrogen gas, argon, krypton, hydrogen and so on .This lamp requires more energy than TL lamp to get the same light level. This bulb or regular bulb only lasts 1000 hours or for an average of 10 hours a night, lasting only about 3-4 months, and after that we have to buy a new bulb.
