We all know what LEDs are. In fact, some of your household light bulbs are probably LED lights. As a result, most people understand that LED light bulbs last forever. LED stands for light-emitting diode. The LED is a light powered by electric currents. When electrons recombine with electron holes, it releases energy or photons. The color of each LED corresponds directly to the energy released by the photon.
Laser projectors are great for many reasons. Firstly, their simple machines that work out of the box. The laser is not hot, which means the machine will last longer overall.
Because of this, maintenance for laser projectors is almost non-existent. Although laser projectors are bulkier than the rest, these projectors are easy to install. Other projectors can only be installed according to how the lamp illuminates, but a laser can be installed in any direction. A laser also emits high-quality colors and brighter images. However, the price for laser projectors is higher than other models. So does the quality and maintenance of each machine. Will you use it outdoor or indoors?
Is it business or pleasure? How much will you use it? Any mains voltage interruption or power cut, however short, would produce these kinds of issues unless a backup power supply was incorporated to cover this eventuality. Lamp manufacturers generally specify lamp life as the Median, rather than the Average Life. Median signifies middle, and it is not what most people think of as an average! For example, the Median Life of lamps would be calculated once the 50th lamp in the sample had failed.
If the specification for a lamp was hours, at least 50 of the lamps in the sample should still be working after this time had elapsed in order for the Median Life value to be valid. Average Life would be calculated by recording the number of hours that each lamp was lit before failing, then dividing the total number hours by the number of lamps in the sample. Depending on the sample size, the Average Life could be higher or lower than the Median Life; there is no relationship between these values.
It is not possible to deduce from the lamp specification how long a lamp will last. It must also be understood that the brightness of the lamp will be reduced with use, over time. We use cookies to personalise contents and ads. Skip to Main Content.
Search Search. How do I prolong the life of my DLP projector and lamp? Information Detail. Switching the projector on and off The projector should be shut down as indicated in the user manual, using the green power button on the remote control.
Cleaning To ensure the projector operates reliably, it is crucial to keep air vents and the projector case clean and free of dust. General lamp failure Although it is anticipated that a projector lamp will continue to operate satisfactorily throughout its working life, occasionally a lamp may fail before that anticipated time has elapsed.
Usage lamp failure As a projector lamp ages, the ends of the two electrodes within the strike chamber cavity gradually erode, and the gap between them slowly increases. Temperature related lamp failure It is very important to shut down the projector correctly after use.

And, to add insult to injury, you have to be careful disposing of your old lamp, because it may contain mercury though Wikipedia claims halogen lamps do not have mercury. Don't get me wrong. I do like my TV--I think the picture quality is quite good.
Monday Night Football broadcasts in high def are just gorgeous, but my TV also needed two separate repairs during the first year of its life under warranty, fortunately. I received an e-mail which claims that "bulbs manufactured early on didn't come close to the suggested life span of the manufacturer but improvements to the bulbs and process since should have them coming very close to the suggested life span. This person said I should view the 10, hour claim as an MTBF, but even if the 10, hours figure is an "average" value, this person is the first person I've had inform me that they got over 10, hours estimated on a bulb I think maybe one other person got north of 8, hours , so I still don't buy 10, hours as an MTBF, especially back in when I purchased my LG DLP TV.
He claims that re-seating the bulb extends the life. While holding that button, press and hold the MENU button on your remote. While holding that button, press and hold the MUTE button on the remote. Make a note of the lamp hours if you want.
