Don’t Only “Think Big, See Big” With Projector Lamps

If you are looking for a good presentation, you definitely need to use an
audio visual aid. As such, projector lamps are an indispensable device used
in business and educational organizations, where they are used to transfer
images from a multimedia projector on to a larger and wider screen.

These lamps have actually replaced the halogen bulbs that were used earlier
and that gave a yellow tone to the images. On the other hand, the projector
lamps basically use metal halide bulbs (mostly mercury vapor bulbs) that
produce excellent white light and thus enhances the quality of the image.

These lamps do not only have professional uses, but are also used widely at
homes for movie or home theaters. They can send the movie or film images on
the big screen for a larger audience to see. The working of the projector
lamp is based on the property of reflection where the lamp shines onto a
number of small mirrors that is placed inside the projector. The image is
then transferred through the air and is finally visible on the screen.

The projector lamps have varied uses – they are used to project films,
slides, as well as images drawn on a transparent plastic sheet. These lamps
are categorized into three main types, namely, slide projectors, multimedia
projectors and overhead projectors. While slide projectors are quite
reasonable and are used solely to project slides measuring 35 millimeters
to demonstrate certain materials at hand, the multimedia projectors are
quite expensive. They have the ability to transfer a film reel, a videotape
or a DVD to a blank wall or a large screen.

Apart from these, there are overhead projectors that have a much simpler
use. They mostly have an educational use, where the teacher or the
demonstrator, uses it to display the content on a blank screen for an
entire class.

Keeping in mind the vitality of these lamps, it is but obvious that these
lamps need proper attention and care. It should be remembered that these
lamps are quite sensitive to movement and moving the projector while the
lamp is on can cause serious damage to the projector. Moreover, care should
be taken while changing the projector lamp, as touching of the glass
housing of the lamp is strictly prohibited. This is because the oil from
our fingers can result in bursting of the lamp, and therefore, it is
recommended that the lamp should be handled only through its metal case.

Last but not the least, these lamps are meant to be used in room
temperatures and extremities of the climate, especially extreme winters,
are quite hazardous for the lamp.

With the advent of latest technologies, the life expectancy of projector
lamps has increased from 1000 hours to almost 2000 hours. Some of the most
expensive multimedia projectors also have an astonishing life of 4000 to
6000 hours. However, older models also show an extended life if used
properly, particularly if they are used in an economy-mode, where the
setting uses less brightness from the lamp.

Thus, by sacrificing a little brightness, you can save a lot of money as
your projector lamp lasts quite longer. Hence, you can bring in the space
age to your living rooms, classrooms and conference rooms with these
amazing projector lamps.
