About Projectors
Projectors receive data from a computer or video source and project this data onto a screen via internal light sources, power sources and converters. Projectors include electronic devices that display video and computer-based images or presentations and transparency devices that use a light source and lens to project an image from a transparent film medium.
Projectors are commonly used in classrooms and conference rooms for presentations. A slide projector is an opto-electronic projector that uses a light source – usually a fan-cooled light bulb, a reflector, a slide holder, a focusing lens, and a condensing lens. Light from the bulb passes through the transparent slide and focusing lens and the image is projected on a screen or wall. The most common slide projector is a carousel projector that uses a stepper motor to advance the carousel and load the slide into the holder in succession. An overhead projector is also a transparency projector that uses a bright light source and lens to collimate the light. Overhead projectors consist of a flat light box with a mirror attached by a flex arm to the box. The mirror reflects the enlarged image of the transparency on the wall.
