LCD projector lamp:

Some people call them LCD projector lamp; the correct term is LCD projector lamp. LCD projector lamp is one of the few parts of a projector that can be replaced.

Lamp type is related to the image brightness. The most common types of projector lamp are listed below:
• UHP - Ultra High Performance
• UHE - Ultra High Efficiency (most common)
• Some projectors also use metal halide lamps

Lamp life or an LCD projector bulb is rated in hours. The typical lamp life for a projector is between 1,000 and 4,000 hours and depending on how much the projector is used, can add to the total cost of operating a projector over a given period of time. LCD projector bulb replacements run anywhere from $300 to $600 each. A lower watt lamp will stay cooler and last longer than a higher watt bulb. Since it uses less power, it will also cost less to operate.

LCD Projectors (Liquid Crystal Display)

LCD Projectors function by spotless light through transparent LCD cells. Most LCD projectors us advanced polysillicon LCDs, which use three separate color panels (red, green, and blue) to produce the preferred color. Projected images are produced by the combination of light shinning through the LCD cells. LCDs have excellent color saturation, usually have adjustable brightness and contrast, are typically brighter than DLPs at the same lumen output, and they have a broader range of connectivity.

DLP Projector (Digital Light Processing)

DLP projectors were developed by Texas Instruments and project images by reflecting lights against hundreds of little mirrors called digital micro devices (DMD). Each mirror representing one pixel is powered by electronics that adjust the angle of the mirror according to the color being displayed. DLP projectors are lighter in weight than their LCD counterparts. They are all digital technology and typically have higher contrast ratios, meaning that they project video images better than LCDs. They are portable, tend to be smaller and lighter than LCD projectors and connect easily to other digital devices.

Projector lamp can transfer an image from multimedia projector onto a big screen for audience to view. They convey information to all kinds of audience from business organizations to education organizations.

Halogen Bulbs are mainly used for projection purpose for many years. These halogen bulbs produce a yellow tone on images. Projector lamps produce white light with the help of metal halide bulb. The produced white light shines onto a number of small glasses in the projector and passes the image through air and onto the screen. There are three main types of projector lamps overhead projector lamps, slide projectors and multimedia.

They have a flat surface. The image created by the bulb is sent to a special type of mirror which makes the image bigger and projects onto a blank screen. These type of overhead projectors are used in class rooms for education purposes. Business people can also use these in conference and meetings.

They contain a special slot for 35 millimeter slide. Slide shows are best used by business people and teachers who rely on demonstrating things. Photographers use these for special photography projects. They are easy to store and you can rely on them for long time.

The multimedia projectors are the most expensive. They project images, videos to a movie screen or onto a wall. They are used at movie theaters and expensive home
