Large Venue projectors are typically found in auditoriums, churches, theaters, trade shows, concerts, and other large venue events.. They are high lumen projectors capable of projecting large images for a wide variety of content. Also stacking large projectors multiply lumen output. Projectors are also categorized according the type of producing the projection like DLP, LCD and the resolution output as high definition projection and standard definition projection.
Some uses of high lumen projectors are:
Large screen projection
large projection on trees posts etc
Some of the projection companies we use:
BARCO PROJECTOR, CHRISTIE PROJECTOR, SONY PROJECTOR, SANYO PROJECTOR, EPSON PROJECTOR, NEC PROJECTOR, BENQ PROJECTOR, OPTOMA PROJECTOR
History of projectors
Projectors have advanced greatly over the years. Things have come a long way since the "Zoopraxiscope" was presented to a wondering public in the 1870s. This was a glass disk with images etched upon it that was spun around while light shined through it. It made images appear to move.
Even a shadow puppet on a wall might be thought of as a forerunner of the projector. In many ways, the idea is the same; a light shines through a medium and the medium creates recognizable images on a wall or screen. Put two fingers before a flashlight, move it up and down, and you have a projection of a bunny.
After the Zoopraxiscope, such renown names as Lumiere and Edison appear. Lumiere developed the Cinematographe (1895) and Edison presented his Kinetoscope (1891) and Vitascope (1896), inventions which eventually led to films being presented to the paying public.
Soon projectors of information other than films and documentaries became popular. Slide projectors came into homes - the slides had to be specially made by development laboratories. But the cost of this was soon brought into reach of most Americans by the Kodak corporation. Slide projection devices, with their preloaded carousels, soon found their way into business presentations. But for interactive projection nothing beat the overhead projector which featured a lighted base, with clear sheets, the same size as paper, that could be printed with images and even written on by a lecturer as viewers watched from their seats. The image was projected up to a triangular shaped device that turned the image and projected it onto a wall or screen. The days of teachers, their faces lit with eerie low-level lighting, scribbling on a clear sheet as students looked on is etched in the memory of a whole generation of students.
Though overhead projectors may still be found here and there, they have mostly been thrown over for the new LCD and DLP projectors. These are light-weight, but still have powerful projection ability. They are also versatile in that they may be connected to many different devices.
One popular use of the projector is in the home. This is a surprising development to some, but it simply makes sense. A projector might be purchased instead of a large screen TV. The projector can project even the most mundane television show on a large screen or even the wall. This is normally less expensive than buying a large screen HDTV, but does an impressive job of presenting sporting events and movies.
Of course, light-weight projectors have become almost a required part of the baggage of sales and business people who must travel and make presentations. Fairly spectacular multi-media presentations can be created using Microsoft's PowerPoint or some similar tool.
Civic organizations and governmental bodies as well as the military have all found uses for projectors in making briefings, informing people of ancillary information at meetings and more.
Churches are jazzing up their services with projectors. Using multimedia to get their message across. Some have even given up printing bulletins and now conduct their entire service with Powerpoint. This saves on paper, allows for last minute changes, and also saves labor.
Projectors are even used by clubs and other organizations. At chess tournaments, projectors are used to show an audience the position of play as well as the time remaining on the chess clock. Projectors can even be used to create holiday displays, and decorations for events such as weddings and parties.
If you are planning to acquire a projector for these or any other reasons, you will want to have a more intricate knowledge of the basic features available on projectors.
