LED technology opens a new situation in the development of projectors

In the field of today's projector, the most noticeable is the development and application of LED light source technology. Optoma released only 80 grams of PK-101, Samsung released P400 brightness reached 150 lumens. The use of LED technology makes the projector in the volume, light source life, the use of the scope of application methods have been substantial changes. These new products at the same time demonstrate the strong potential of LED technology, but also opened a new situation in the development of the projector.

Compared with the traditional light bulb, LED light source package has a very obvious advantage in terms of volume, service life, power consumption and heat, color performance, and LED does not contain harmful substances. Through the use of LED light source, the projector can be done very lightweight, such as Optoma released PK-101, weighs only 80 grams, the size and the equivalent of ordinary phones. DELL released a preliminary application of LED light source technology projector weight is only 360 grams. Visible, through the LED light source, the projector can be easily made pocket products, to achieve a true sense of carrying. And LED light source technology in power consumption, heating area is also very outstanding, compared with the traditional lighting technology, had more than 30% lower, which makes the design of cooling system of projector products is very simple, it can not only for the projector can also reduce the burden of products used in the process of noise.

The long service life of LED light source is more than the traditional bulb can not compare the advantages of its application will enable the user to use the concept of the projector and the application of a substantial change in the way. Projector lamp life is generally in 2000~3000 hours, through the application of a variety of energy-saving technologies, to achieve 4000 hours even if the long life. Not only that, but more importantly, the projector bulb prices are quite expensive. It is for this reason, for the vast majority of users, the projector is only a necessary moment to use the product, which largely limits the use of projector products. The LED light source projector life is generally in the tens of thousands of hours, life is no longer the projector supplies indicators. Bowflex technology general manager Shen Qing said, "this is a revolutionary technology, the user does not need to consider the lamp life this very headache index. To solve this problem, the projector can really use up. Obviously, LED technology can be widely used in projector products, will allow users to more easily accept the projector products, which makes the projector to be more widely used.

In terms of technology, brightness is the biggest obstacle to the wide application of LED light source. Currently, the application of LED light source projector brightness is generally about 100 lumens, compared with the traditional projector brightness of thousands of lumens is not competitive. However, this problem is being resolved, Samsung's latest release of P400 brightness has reached 150 lumens, compared with the previous generation of products has increased by 3 times. Believe that with the continuous evolution of technology, LED light source will be more widely used in projector products.
