Projector Lamps

Projector lamps are used as the light source in projecting devices. For example; a movie projector is a device for displaying moving pictures, and this is achieved by projecting them onto a large screen which is usually set at some given distance from the movie projector. These types of projectors are known as opto-mechanical devices.

There are many different types of devices and projectors about today and most of them will usually require some type of light source.

The size and shape of projector lamps and bulbs vary enormously due to the huge range and types of projecting equipment that is available in the market today. A bulb that is suited to the old type movie projector, will be very different from the lamp or lamps that are required to fit into a rear projection television, and will function in a very different way.

There are many different types of Projector Lamps available and some of these will include:



· Projection cubes

· Interactive whiteboards & rear projection TV bulbs

The lamps may be installed by a specialist or in many cases installed by the projector owner or operator. To install a lamp or bulb always make sure the screws or bolts of the terminals are not too tight as theses can break the ceramic part and damage the isolation of the lamp. However if they are not tight enough, they can cause too big a charge on the ballast causing it to break.

Always make sure the bulb is well housed in its cartridge. There may be a tendency to stop at the first sign of resistance. Continue applying pressure on the base of the bulb until it is well fixed within the cartridge.

Projector lamp terminology can be a bit confusing. Here are a few terms explained;

Lamp modules: are made up of two elements; the lamp or bulb and the cage or housing which includes an electrical connector.

Lamps: are high performance lights

Original lamps: are developed by the original lamp developer

Compatible lamps: are lamps that are not the same type as the original lamp.

Copy lamps: are lamps produced by unregulated manufacturing companies.

Things to Remember When Buying Dell Projector Lamps

It's never a good idea to wait until Dell projector lamps lamp blow before buying replacements. People avoid keeping a spare because they think Dell lamps are expensive. However, this is false economy - without a working lamp, a projector is just a piece of useless hardware, so why take the risk? Besides, it isn't always necessary to buy branded products. There are unbranded Dell projector lamps that are just as good as the genuine manufacturer's replacement - except they lack the Dell logo and accompanying price tag.

The important thing to ensure when buying unbranded Dell lamps is that they are made to the same high standards as the original. This means seeking out a reputable supplier - preferably, someone who sells both unbranded Dell projector lamps and the manufacturer's original versions. This company will value its customers highly, know their products and will be keen on maintaining good relationships with Dell.

The most important influence on cost is the lifespan of the lamp. Depending on the manufacturer, Dell lamps can last anywhere from 1000 to over 4000 hours. However, this must be offset against the manufacturing quality. It is pointless buying a cheap 4000 hour lamp if the bulb blows the moment the projector is moved.

Remember, though, that this works the other way, too. Original projector lamps have a finite lifespan - they are designed to need replacing after a safe number of hours by the brand manufacturer. This ensures that old lamps won't damage the projector, but it also means you may get a longer life from an original.

Original Dell projector lamps are high quality products that are designed to last a long time and using these branded lamps ensures your projector model is covered under the manufacturer's guarantee. However, good quality unbranded alternatives can be made to exactly the same stringent specifications. The best way to know what you're getting is by checking the "kite" mark. All lamps must undergo strict quality control tests to ensure the potentially dangerous mercury vapour does not come into contact with the outside air, and that users are protected from the dangers of shattering glass. They must also have the density of mercury vapour laid down by Dell.

Although buying online is cheaper than buying offline, don't be lulled into a false sense of security by so-called Dell projector lamps which seem unrealistically cheap. Just as with perfumes and fashions, there are fake projector lamps on the market which use realistic branding and packaging to create "manufacturer's original" products which are nothing of the sort. Invariably they have been made in cheap foreign sweat-shops where safety and quality control is non-existent. It is far safer to buy a quality checked, but unbranded lamp from a trusted supplier.

When it comes to Dell projector lamps, most people play safe and buy the original from a reputable known stockist. However, this often means they take a chance and don't keep a spare. A far better option is to have the manufacturer's original lamp fitted, and then order a low cost non-branded "spare" from a trusted supplier who offers a money-back guarantee. That way, you are covered from all angles.

Projector and Projector Lamps

Every person who has experience in business knows that it is impossible to make a lasting impact without audio visual aids. So for a good presentation one needs to have projectors. They are indispensable. Projector lamps are things one can not do without in business and also educational arenas. They help transfer images from a multimedia projector on to a large screen so that you can deliver your sales pitch or information with the help of visuals.

At first projectors were run on halogen lamps, which gave a yellow tone to the images. Now lamps use metal halide bulbs (mercury vapor) that produce excellent white light and give sharp images.

Not only are these lamps being used in business but are also increasingly being used in homes and informal settings to view movies on home theatres. Home theatres have wide screens on which the images from the projector are magnified using properties of reflection and transferred on to the screen.

These projector lamps can be used in many ways; they project films, slides and even images on transparent plastic sheet. You can easily make out from their names i.e. slide projectors, multimedia projectors and overhead projectors. Slide projectors are priced reasonably but others are expensive to purchase. Now, apart from these projectors listed above, we also have the most commonly used projectors, i.e. the overhead projectors. These are commonly found in schools where instructors use them to display information on a screen. These projectors enliven a class room and make even the dry-as-dust facts palatable and easily understandable for the students.

The lamp can be called the heart of the projector. No lamp - no image! So the lamps need to be taken care of. They are sensitive to movement and are fragile. Since they can be damaged easily, care should be taken while moving the projector. Always allow the projector to cool down before moving it. While changing lamps care should also be taken. Touching the glass housing, however inadvertently can cause the lamp to burst since our skin has a layer of oil. Therefore it is better to handle the lamp only via its metal case. Another important precaution to take is to keep the projector and the lamp at room temperature. Extreme weather (especially winters) can be hazardous to the lamp's life.

Even though technology has improved and with it the life span of projector lamps has also increased. Whereas it was 1000 hours earlier, now lamp life is up to 2000 hours. However lamps are expensive and using all the precautions is advisable. Whenever possible, one should use the lamp in economy mode. The images are less bright but the lamp life-span is not affected. By compromising a bit on the brightness, the projector lamp lasts longer.

Exercising these very small precautions makes it much easier to not only enliven a class room but also make a significant impact in the conference room or even watch a movie at home on a wide home theatre screen. You will not have to worry about the costs of the lamp or bother with frequently changing the lamp.

Keep the Light Burning on Your Digital Projector Lamp

A digital projector is a wonderful way to watch television and movies, and its popularity is on the rise. The one complaint that people have about the projector is that the lamp burns out too soon. That is something that can be fixed, though. If users would heed certain advice, they would be able to keep their lamp burning for much longer than the average projector owner.

When you first get your digital projector, invest in a surge protector. If a digital projector is exposed to electrical surges, the lamp is more likely to burn out before it is supposed to. Users can avoid that from happening by simply plugging the projector into a surge protector.

Once you have purchased the surge protector, dust the room you are going to put the projector in. Dust and projectors do not get along. If you keep your projector free of dust, your lamp will also be able to burn longer. Make sure that you dust the room frequently, as dust can creep up in a room. It is important that you stay on top of it for the health of your projector and lamp. If your projector has dust filters, make sure you take them out regularly and clean them too.

You can also adjust the mode in which your projector runs in order to lengthen the life of your bulb. If you use the economy mode on your projector you will be able to get more use out of the bulb before it needs to be replaced. In most cases, you will not even notice a difference in picture when you switch to economy mode ( however if you seek a perfect picture this may not be the best option). This is the easiest way to increase the time between changing bulbs.

Also, be mindful of how often you turn the projector on and off. A lot of stress can be put on a projector and its lamp if it is switched on and off often. As a rule, keep from turning the projector on and off often in order to increase not only the life of the projector lamp, but the life of the actual projector as well.

When your projector is on, you need to keep your eye on it to make sure that the lamp does not overheat. If you allow your lamp to overheat, the chances of it burning out quickly are increased. Instead, make sure that the lamp does not overheat so you can optimize performance and get the most out of the lifespan. Do not block any fans.

A digital projector is a great way to bring theater quality entertainment into your home. By keeping an eye on the lamp and how you use it, you can get more hours of use out of it. If you want to be able to keep your projector low maintenance, follow these tips and you will have a much easier time handling your projector and lamp. Also, you will save money because you will not have to replace the bulbs as often.
