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.

Are you looking for a big screen TV with a not so expensive price tag? Then, a rear projection TV is one option you should consider. When it comes to combining low price and high performance, rear projector TVs are the best. Though there are several projection technologies in use, Digital Light Processing (DLP) projector technology is the most popular one.

Advantages of DLP Technology

DLP technology, originally developed by Texas Instruments, incorporates an optical semiconductor called the DLP chip. With this you can expect superb black level performance and deep saturated colors apart from excellent image uniformity. Televisions with DLP technology deliver bright images, so you can place them even in well-lit rooms. The ultra-fast DLP chip also makes them ideal for watching sports and fast action.

The rear projection TV houses a projector, which streams the image from behind the screen. A DLP projector has four main components, namely a color wheel, DMD chip, light, and optics. The DLP TV lamp is the main light source of a rear projection TV. A DLP TV lamp has so many positive aspects.

First and foremost, these projection TV lamps have a much longer life of about 70,000 hours when compared to Plasma TVs. The next big advantage is that replacing a rear projection TV lamp is not so expensive. It is also simple and takes only a few minutes. So do not panic when your TV starts going dim. All you need to do is replace the DLP TV lamp. There is no better place than BulbToGo.com to look for a good projector replacement lamp.
