In schools and other educational settings, they are sometimes connected to an interactive whiteboard. Video projectors are used for many applications such as conference room presentations, classroom training, home cinema, movie theaters and concerts, having mostly replaced overhead, slide and conventional film projectors. Projectors using RB lasers use a blue laser with a phosphor wheel in conjunction with a conventional solid state red laser. Each projector can use up to two racks, and several monochrome lasers are mounted on each rack, the light of which is mixed and transmitted to the projector booth using optical fibers. Remote fiber optic RGB laser racks can be placed far away from the projector, and several racks can be housed in a single, central room. (White LEDs do not use lasers.) A wheel is used in order to prolong the lifespan of the phosphor, as it is degraded by the heat generated by the laser diode. If a blue laser is used, a phosphor wheel is used to turn blue light into white light, which is also the case with white LEDs. Video projectors use a very bright ultra-high-performance lamp (a special mercury arc lamp), Xenon arc lamp, LED or solid state blue, RB, RGB or remote fiber optic RGB lasers to provide the illumination required to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings.
