There are many times that one is not aware of the projector lamp that he
needs and still sets out to buy it. Here our aim is to give you much
information as we can on all types of projector lamps for sale. Did you
know that a projector bulb dos not last forever and eventually will need to
be changed? Well this is because it loses its power and goes out at some
point of time making the images and their colors faint.
The contrast too will decrease over time. When replacing the bulb as well
you will need to know about what you need or else you could go terribly
wrong with your choice. The best idea at this point would be to replace the
entire projector lamp to ensure that everything goes smoothly. This also
ensures that there is no damage to the bulb while replacing it. In most
cases this is also the only way to make sure that you still are under the
warranty of the seller.
Different types of projector lamps available:
There are basically three types available and they are overhead projector
lamps, slide projector lamps and multimedia projector bulbs.
Overhead lamps – This is a projector that is often used in educational
institutions which have large amount of students in the same class. The
projector is basically placed under a very bright bulb. This brightness of
the light send the image to a mirror within the projector which in turn
makes the image larger and then sends it out on the empty screen as a large
picture. This may eve be used by various business men if there is a
business conference or meeting in the works. It makes a lot more sense to
project the statistics rather than giving everyone handout or making
several copies. Using this kind of a projector helps the presenter talk to
the whole crowd as one and not at an individual basis. This kind of a
projector is the cheapest in business.
Slide projectors- This kind of a projector has a special area where slides
can be inserted. These slides have to be 35 millimeter. Each of the image
that is on this 35 mm slide will then be made to look a lot larger and then
will be projected on to the screen that is large and blank. Again
educational institutes as well as business professionals will find these
kind of projectors to be incredibly useful. When using to see objects that
are normally photographs, this is very helpful. This projector is slightly
more expensive than an overhead projector lamp.
Multimedia projector lamps – These kind of lamps are the most expensive of
the projector lamps. This is basically a continuous stream from videotapes
or reels of films or more lately DVDs. The images are then made to look a
lot larger and the projected. When you go to a movie theatre remember that
this is what they probably might be using to show you the movie.
