A lamp holds great importance in once life. They are the source of light and make thing visible to you. When light is emitted from a lamp, it travels in all direction and after striking from a surface it comes to our eyes and the object is visible to you.

It can be used as a study lamp, a table lamp, light bulb (a kind of lamp ) or a emergency lamp. Previously lamps were made from electric bulbs and CFL but now a days lamps are being build by LED.
