lamps projectors |
Hello, I'm Dave. New lamps projectors are supplied with a new lamp fitted, which for the average projector lasts around 2,000 hours. For business use, using a projector 7 hours a day, 5 days a week, the lamp should last over a year.
Lamps Projectors Advice
Replacement lamps or lamp modules Majority of projector lamp manufacturers give a 3 months RTB warranty on new lamps. This warranty commences from date of purchase/invoice. Lamps or lamp modules Manufacturers lamps projectors vary, but can be sold as "lamp only" or as a lamp module, as shown above. When replacing a new lamp into the existing lamp module housing, a suitably qualified electrician or on-site professional should only undertake it. It is important to ensure the terminals are not over tightened as the ceramic can be cracked and reduce the electronic insulation of the bulb. Similarly, if the bulb is under tightened, it can cause arcing on the terminal, which puts undue load on the ballast that can lead to failure. Lamp modules are more common place and can be likened to car headlights, where you buy the "unit" which just slots in. To replace a lamp module, you simply undue the necessary screws on your projector, lift out the old lamp module, insert the new lamp module and tighten the screws. Obviously, specific instructions on how to replace bulb modules will vary slightly from projector to projector, so the instruction manual should be consulted and the replacement undertaken by a suitably qualified person. Useful tips on prolonging lamp life Never touch the lamp with your fingers, always use a cloth for handling. Deposits from fingerprints cause temperature "hot spots" and temperature gradient stresses the glass often resulting in earlier lamp failure. Keep the air filters of your projector clean as block filters make the lamp overheat, possibly causing earlier lamp failure. There should always be good airflow around the projector. Always switch off lamps projectors using the remote control and not by disconnecting the power. The projector will invariably go into a cool down mode where the image is turned off and the fan accelerates to cool the lamp in a controlled manner. The temperature of an operating lamp is many 1,000's of degrees, so if you disconnect the power to the projector, prior to the above process, the glass in the lamp will cool unevenly and will result in stress fracture, causing early lamp failure. We are led to believe that you can shorten your lamps projectors lamp life by up to 50% simply by disconnecting the power instead of switching off the projector by remote control and allowing the natural cooling process to take place. Lamp failure can also be due to mechanical shock and vibration. A hot lamp filament is fragile and you should always ensure the unit is turned off and the lamp is cool before moving the projector. If your projector has a high/low lamp/lamp switch, you can extend your average lamp life by using the "low lamp/lamp" position whenever possible.
Things You Need to Know When Choosing and Buying Projector a Bulb
The kind of projector lamp you should buy depends on the kind of projector you have and its model. Old models, those models before year 2000, have a life of about 1000 hours. New versions of projector lamps has more than double lasting power and can stay alight for about 2000 hours or even more. However, some brands can stay much longer. There are even lamps that stay burning for 6 thousand continual hours. There are the ones whose life may depend on the brightness, such that when you turn down the brightness, you add more hours to its staying power. If you want to lengthen the life of your projector lamp, use only a certain enough brightness you need. You will know you need to replace the bulb when the image begins to dim.
If the projector bulb you bought has a warranty certificate, be wise by keeping it. You may need that piece of paper suppose the projector bulb goes out a week after it has been bought. Nevertheless, the chances of this occurring may be too slim as most products run through a series of inspections and tests before being released into the market. Warranty period for bulbs of most projector lamps is either 60 or 90 days from receiving the projector. If you live in a place where it gets bitterly cold during winter, remember that projector lamps find low temperatures unfavorable for operations. Transporting the projector from outdoor winter cold to a warm indoor environment and quickly turning the equipment on, the lamp or projector bulb may explode due to sudden temperature shift. Hence, there is a need to let the device to warm and adapt to the surrounding indoor temperature before switching it on. This avoids the hazard of explosion due to extreme change in temperature. Another thing you must avoid is moving or shaking your projector while it is turned on and in use. Keep it still because movements can affect the electronic components of this equipment, which are particularly sensitive. If you want your device to last this one tip should be observed. The lamp is also susceptible to damage upon movement while in use. Attempt not to move the projector, let alone shake it, while it is in use. Upon turning it off, wait for a few while before moving it. This adds more hours to your projector lamp life. There are brands of projector that has eco-mode settings to allow you to decrease the brightness of the lamp. This economy mode setting allows you to set the brightness that is just enough for the device to be functional, just enough for the image to be clearly visible. This is particularly an advantage if you wish to prolong the life of your projector lamp, and this could save you some cash. For instance, a projector bulb whose brightness is at 2000 lumens and a staying power of 2000 hours may be set to a lower brightness setting, say 1600 lumens, but could last for 3000 hours. That means it could run for another one thousand hours. That saves you another one thousand hours without buying a new bulb for your projector. Projector bulbs are fairly costly but the prices depend on the brightness and quality. It is advised that you buy an extra lamp upon purchasing a projector to spare you from trouble in case of emergencies.

With a number of different projectors, we can get confused. The solution is simplicity. We know that there are a number of brands. One such brand is InFocus projector, and here is why I like InFocus projectors. The biggest reason to buy a InFocus projector is that unlike other brands, they are focused on one thing, and that is projectors. Take a look at Panasonic, Sony, and the other brands, and you find that they are focused on all different aspects of technology. Sony for example deals with televisions, consumer devices, such as MP3's, and gaming consoles. This applies with Panasonic also, which makes all different consumer electronic products. The InFocus projector company is a company focused on projectors. What I have found that sets them apart, is in the multimedia projector niche. Whereas most projectors of today deal with being a projector, the InFocus projectors have been focused to work with consumer electronic devices of today. For example, recently they teamed up with a company to make USB connectivity better in their projectors. The result? You can more easily connect your laptop and give presentations, watch a movie or play a game. The other good news is that there is a wide variety of models. So finding one which meets your specific needs is a process which can be done. Article Source: http://EzineArticles.com/?expert=Sarah_Reddingworth
