A projector is a machine that will project slides or other visual material
onto a screen. A projector requires a projector bulb to function. There are
different types of projectors and each requires a different type.
The type that is used for a slide projector one of the main elements of a
slide projector is a projector bulb. For a slide projector an incandescent
one is the type that is used. Usually the incandescent one is fan cooled to
keep it from getting too hot and causing damage to the rest of the
components of the projector.
Movie projectors typically use a xenon arc lamp. This type has been around
for awhile and relies on xenon gas compressed at high rates to operate.
Over head projectors are favored in the classroom and use a diachronic
reflector type. This type looks like a flood light. This is also a fan
cooled incandescent light, but it has reflective material built into it.
With new technology has come a new type, LED technology has produced a LED
type, and this type primarily geared toward use in home projectors has not
really caught on, because of the brightness factor. The LED bulb tends to
have a yellowish cast to it and can disrupt the colors of the images being
projected. Over time with technological improvements the LED bulb may
improve, they are cheaper to use and have a longer life, so if the
improvements can be made to the color they project than they will become
very popular alternatives to the incandescent bulbs.
Cost of a Bulb
The bulb is costly. The prices range between fifteen and one hundred
dollars. Usually the life span is not that great either, but most of the
home use is not excessive so the bulb does not burn out as quickly, usually
business and school applications will go through bulbs much quicker.
Purchasing a Bulb
A projector bulb can be purchased directly from the manufacturer of the
projector or through some office supply stores. Some are very easy to find
some are not. There are online sources for finding a bulb. The series make
and model will be needed to make sure you order the correct bulb. A bulb is
usually pretty specific to a given model so there really is not a lot of
lead way in purchasing generic options.
