LED light source will play an important role in the projector's new light source

July 08, 2023

In the past one or two years, the "LED light source" with high frequency appeared in the field of liquid crystal displays and television appeared in a brand-new image. At major exhibitions, LED light sources are widely used in projectors of many brands at home and abroad. LED light sources are also considered as new alternatives to traditional projector metal halide bulbs and popular ultra-high pressure mercury bulbs.

Since the LED light source is a cold light source, compared with the traditional projection light bulb, it has the advantages of low heat generation, long service life of 20,000 hours, and the like. Therefore, the size of a projector using an LED light source can be made as large as a mobile phone, and it is not necessary to replace the light bulb in about two years as in an ordinary projector. From an industrial point of view, LED light sources are used in projectors as much as a technology upgrade.

When the projector's core component, the light source, enters the LED era, what impact will this have on the projector market in 2009? Below we will analyze with readers and friends.

LED light source breaks the brightness bottleneck

LED light source used in projectors began as early as three or four years ago, but because the brightness is only a few lumens to 10 lumens, can not meet the needs of daily projectors thousands of lumens, so the LED light source projector is always stay in the experiment Chamber stage without mass production.


However, LED light source brightness bottleneck finally achieved a breakthrough in 2008. Projector bulb manufacturer Osram Germany announced in late 2008 that it has developed the latest LED light source system that uses five LED bulbs to increase the brightness of this light source to more than 500 lumens. Several LED1080p projectors exhibited at the CES 2009 Consumer Electronics Show also claimed to have a brightness of 700 lumens or more. Among them, Qiling Technology from Taiwan in China announced that the brightness of its LED projectors has exceeded 1,000 lumens. Some of these products are all described, the brightness of the LED light source is already very close to the brightness of ordinary projectors.

Editor's point of view: The above-mentioned many news are all conveying to us such a fact: From 2009 till now, the opportunity that LED light source is applied to the projector has already matured. After solving the problem of low brightness, the low heat output of the LED light source can make the projector more compact, which means that future business projectors will truly realize the size of the handheld. In addition, the life of the 20,000-hour LED light source basically eliminates the need to replace the lamp after the projector is used for a period of time, and the user's cost of use will be greatly reduced. However, we cannot ignore the possibility of high production costs brought about by the low penetration rate of LED light source applications. However, in the long run, LED light sources will certainly replace the existing metal halide bulbs and the popular ultra-high pressure mercury bulbs, becoming a new type of light source for projectors.
