Projector bulbs, Projector lamps: New End Technology Inspired with Innovation and Excellence
With the advent of technology and breakthrough developments in science, technology and communication; a new verge of projector lamp is dominating the market paradigm. It is a perfect example of latest technology embodied with innovation at an affordable price. There are led and DLP projectors in market both are suited for home theaters which offer multi dimensional technology at an affordable price. Technically, they are called high intensity discharge lamps because they produce light from a very small electrical discharge. Hence, we use less energy to give brighter light. It is very advantageous to use them because they not only help conserve energy, but also work for a long period of time.
Ordinary projector lamps are made of halogen which produces the light necessary for the input of the projectors. But halogen projector bulbs have characteristic that they produce a streak of yellow light and so the original color of the image or text is disrupted. Projector bulbs are made of metal halide for projection. This is much better since they produce white light and remove the presence of yellow shade in the information being projected. This also improves the clarity of the information. Projector lamp is very effective in business presentations they give high quality image size using resolution such as SVGA XGA SXGA+.
On an average, projector bulbs have life span from 1000 to 4000 hours. They are very economical and cost efficient projector bulbs ever. Bulbs are the most significant aspect of a projector lamp; the entire life span and brightness effects of a projector lamp depend upon bulb. These lamps are available in different choices each representing different wattage. First determine the lamp requirements which are required for tour projector; understand the usage levels and determine product specifications.try to go through its manual it will guide you in a much better way. To ensure that it gives proper functioning it is very important to change bulbs after a certain time period. Now, various companies have jumped in the bandwagon of bulbs but I would recommend use the latest and innovative technology. "Gone are the days when technology was a tool in being a better aid at office work but now it is an important investment."
Projector lamp is widely used in offices to give business presentation to a large conference or in a seminar to explain audience something about the topic of discussion. They are used in schools colleges as well when presentation is given to a large audience. Please do take proper care of projector bulb because if it not working well it will lead to a distorted view and brightness/ contrast will also overlaps.

The Technical Differences between LCD and DLP (from the link below)
LCD (liquid crystal display) projectors usually contain three separate LCD glass panels, one each for red, green, and blue components of the image signal being fed into the projector. As light passes through the LCD panels, individual pixels ("picture elements") can be opened to allow light to pass or closed to block the light, as if each little pixel were fitted with a Venetian blind. This activity modulates the light and produces the image that is projected onto the screen.
DLP ("Digital Light Processing") is a proprietary technology developed by Texas Instruments. It works quite differently than LCD. Instead of having glass panels through which light is passed, the DLP chip is a reflective surface made up of thousands of tiny mirrors. Each mirror represents a single pixel.
In a DLP projector, light from the projector's lamp is directed onto the surface of the DLP chip. The mirrors wobble back and forth, directing light either into the lens path to turn the pixel on, or away from the lens path to turn it off.
In very expensive DLP projectors, there are three separate DLP chips, one each for the red, green, and blue channels. However, in DLP projectors under $20,000, there is only one chip. In order to define color, there is a color wheel that consists of red, green, blue, and sometimes white (clear) filters. This wheel spins between the lamp and the DLP chip and alternates the color of the light hitting the chip from red to green to blue. The mirrors tilt away from or into the lens path based upon how much of each color is required for each pixel at any given moment in time. This activity modulates the light and produces the image that is projected onto the screen.
