Projector Lamp Experts have designed some detailed diagrams to help explain the major components of an average projector and RPTV lamp.
There is often confusion with customers over the difference between a lamp, urner, module and connectors - all of which are important parts to understand when purchasing a projector lamp. Some companies do not sell the complete lamp module which can cause frustration and confusion for customers. This section will explain the different components of a projector lamp and what to look out for.
Typically
when the Audio Visual and IT industry refers to a "projector lamp"
they are actually talking about a complete projector lamp module (rather than
the bare lamp), which includes at a basic level a bare lamp which includes a
burner and reflector (usually made by Osram, Philips or Ushio), plastic module
housing (often called a cage), and connectors.
Please
refer to the diagram below.
The
Burner/High Intensity Discharge Bulb is place inside a reflector creating a
lamp. The lamp is then placed inside a housing or cage specifically designed
for the projector or RPTV. The lamp is then connected to the projector via connectors.
Below is an image of projector lamp housing without a lamp or connectors inside:
Light
is emitted when metal halide atoms in the High Intensity Discharge bulb
(burner) are excited by an electrical discharge between two electrodes in the
bulbous midsection of the bulb.
