THE BULB BLOG

Movie projectors have four main sections namely the spool assembly, the audio assembly, the lens assembly, and the lamp assembly.

• Spool Assembly – The Spool assembly aids in the movement of the film through the projector. It contains parts required for storing and moving the film. Platters, sprockets, and cambers are parts of the spool assembly.

• Audio Assembly- This assembly is the source for sound. Two types of technologies are involved in audio assembly, namely optical and magnetic. The optical system comes with a light source and a photocell and is the most common. On the other hand, the magnetic system comes with a recorder head that is directly in contact with the film.

• Lamp Assembly – The lamp assembly is one of the most important parts of movie projector equipment. It is the primary element of the light source and contains all the parts needed for the illumination of the image on the film. Xenon bulbs are commonly used in movie projectors as they work for thousands of hours with the same intensity. The best part is that even if the bulb dies with usage it can be replaced. In case you require a replacement projector lamp, BulbToGo.com would be an excellent place to go as they offer quality projector lamps at great prices.

• Lens Assembly – The light from the lamp assembly then passes through the picture head and lens assembly. Basically there are two types of lenses, namely flat and Cinemascope. Depending on the movie, the lens can be removed and changed in most movie projectors.
