|A projector lamp is used to transfer an image from a multimedia projector onto a larger screen for an audience to view. The projector lamp has been used in businesses and educational organizations for many years in order to help convey information to an audience. The projector lamp is also used for movie or home theaters, where it sends DVD or film images to a large screen for all to see.
While halogen bulbs were used for many years for projection purposes, halogen produced a yellow tone on the images. A projector relies on an intense light emitted from a mercury vapour lamp, to produce a brilliant white light. The light bulb shines onto a number of small mirrors inside the machine and transfers the image through the air and onto the screen.
