What is an LED projector? And how do they work?
LED is not a display technology. Instead, the LED points to the light source used. LED projectors are a much smaller example than devices that use conventional projector lamps. In order to realize that these projectors are right for you, you need to get enough information about the advantages and disadvantages of this technology. At the same time, a clear example are mini or pico projectors that use this technology due to their small size.
How do LED projectors work?
In LED projectors, instead of using a lamp, these projectors emit red, green, white and blue LED colors. The term “LED” is used for a light emitting diode. When an electrical signal passes through an LED, it creates subatomic particles that must pass through a semiconductor or emiconductor. In this process of reduction, particles release photons. This light is then reflected from a DLP chip or through an LCD chip.
Advantages and disadvantages of LED projectors
The biggest advantage of LED projectors is their lamp life. LEDs last at least 10 times longer than conventional projector lamps. Many LED projectors can operate for up to 10,000 hours or more. Because LED bulbs last as long as the projector itself, you do not have to worry about buying new bulbs. LED projectors are usually small, light and portable. No need to spend time heating or cooling the device.
Also, LED projectors are much quieter than projectors that use conventional light bulbs. By using this type of technology, a wireless internet connection is provided for the user to transfer images from a computer or mobile phone in a few seconds. The biggest drawback of LED projectors is their brightness. Currently, most LED projectors produce only about 10 to 1000 lumens.
It seems that this new technology can be a good option for small and medium conference halls. Unfortunately, we can not use this system in large halls, and of course we should not forget that although laser and LED technology are superior to mercury lamps, but their price is slightly more expensive than the generation of video projector lamps.
