Is it time for you to go to a drum lamp shades or lamp shades? Before you do that, you better read the following article first!
Projection lamps are always an issue or worry inside the Audio Visual Community. Some tips i find to get most troublesome from the technicians perspective, is the fact most customers of Audio Visual Equipment, especially individuals who use Audio Visual Equipment that require using today’s halogen projection lamps, are not aware of the special care required when handling these types of lamps. This lack of knowledge directly effects lifespan expectancy of theses halogen projection lamnps.
Lamp life happens to be significant for end users. As a result of intensity of today’s halogen lamps, as well as the high operating temperatures,lamp life is considerably shorter as opposed to traditional style incandescent lamps. A couple of the most used projection lamps seen in Overhead Projectors today are classified as the “ENX” as well as the “EYB”. Most users miss how the rated average lifetime of theses lamps is 72 hours, a substantial difference from your 200+ hour rating to the incandescent projection lamps of yesterday’s Overhead Projectors. Since Overhead Projectors in many cases are used at the very least 3 to 4 hours a day, 72 hours appears in a short time, sometimes giving the end user the misconception of short lamp life. Substantially reality the projection lamp is burning due to the average expected life.
The most typical application for halogen projection lamps from the Audio Visual Industry today may be the Overhead Projector. The utilization of the previous style incandescent lamps which are necessary to use 120 volts to control in yesterday’s Overhead Projectors Projectors, have usually become obsolete. Sure, it is possible to still find Overhead Projectors who use this old technology within the Educational Community, but today’s new Overhead Projectors don’t utilize these varieties of projection lamps. Today’s Overhead Projectors use halogen lamps that are designed to burn at very good temperatures, yet in many instances only require 82 volts to function. They make a much brighter light output (referred to as lumens) and require the usage of special reflectors or fans to chill.
Now this is in which the trouble generally seems to begin. Special care would need to taken when handling these halogen lamps, specifically when installing them into your projector. They should never be handled with bare hands. The oils from your skin that stick to the projection lamp, might cause burn spots about the shell from the lamp when illuminated, causing the lamp burning unevenly and causing destruction of the lamp and ultimately shortening the life from the projection lamp.
The second cause for concern is the place where the lamp is seated in the lamp socket. In any other case properly seated in the socket the pins in the socket will ark between socket connections as well as the projection lamp pins. This will cause damage to the projection lamp as well as to the projectors lamp socket, shortening living of both lamp and lamp socket. The projection lamp really should be seated into the socket before you feel a slight snap because lamp seats fully into your socket. This is the most common reason for lamp failure, and for that matter lamp socket failure.
There are obviously variables that determine lamp life, however these certainly are the most commons advantages for premature failure that any of us see in this service department every day.
