Born and growing LED growth projection in silence

It is well known that the projector is the same as the more expensive consumables, which has certain service life, when used for a long time the bulb will replace the bulb is aging, the user must consider the problem of the projector, which is a big disadvantage compared to the projection machine of LCD tv. Over the years, the major projector manufacturers continuous research using longer lighting, through a variety of ECO technology to extend the lamp life, even launched a double bulb auto projector and so on, the ultimate aim is to maximize the extension of the user to replace the projector bulb period.

The emergence of LED projection technology, opened a new situation in the development of the projector. Compared with the traditional projector, the biggest advantage of using LED light projector is no need to replace the bulb. At present, the traditional LCD DLP projector lamp life is about 1000 hours to about 3000 hours, and the service life of the bulb LED projector it in 10000-20000 hours or even longer, the user completely without worrying about the loss problem of projector lamp.

The projector using LED light source has the following characteristics:

1, long life, almost no need to consider the use of time

LED (LightEmittingDiode), also known as light-emitting diodes, this technology has long been used in the field of display and lighting. It is the subject of an electroluminescentsemiconductor materials, in which both ends with forward voltage, cathode current flows from the LED anode, semiconductor crystals on the issue from the ultraviolet to infrared light of different colors, the current is strong, the stronger the light. LED light-emitting principle is different from the traditional UHE, UHP bulbs, it does not produce a lot of heat in the process of light, so the life can reach more than 10000 hours.

2, ultra portable, ultra quiet, low heat

Because LED is cold light, not like the work of metal halide lamps generate a lot of heat, and the reduction of the optical structure of the original source requirements of the complex, which can reduce the heat dissipation system of the projector, the volume can be much smaller than the original. From an early age, LED projectors are generally maintained at 1 kg or less, and some even only about 0.5 kg, so that the weight of portable and mobile. And the noise is much smaller.

3, special power, almost no need to consider the issue of electricity

LED projector has the advantages of small volume, low heat, power consumption than traditional light bulbs lit UHP lights (super light), UHE lamp and metal halogen lamp power consumption is much less about the power consumption of 20 Watt, users do not need to worry about power consumption problems.

4, the price can be accepted

Compared with the high price of imported UHP or UHE light source, LED light source is much cheaper than traditional light source. Not only the cost of the light source is reduced, but also the total cost can be well controlled by saving the heat dissipation system and simplifying the optical path structure. Like Optoma's latest handheld LED projector PK-101 retail price of just 3 thousand.
