How do the light comes from projector?
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, typically a projection screen. Most projectors produce an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers.
Projectors that work on LCD (Liquid Crystal Display) technology, uses a bulb as the source of light, and the rojectors that work on DLP (Digital Light Processing), uses a filment lamp as the source of light.
