Projection of the new direction of LED projector worth looking forward to

Recently, around many of my friends asked to buy a projector at home, should choose what kind of machine. A friend asked a number of professional home projector, as well as friends asked some entertainment projector. There is even a friend mentioned to the author should choose LED projector into the family. They think the LED projector when the TV is good, because they are compact, only a little larger than the Walkman, easy to carry and move. The power consumption is low, only 20 Watt power source, there are more than 10 thousand hours of life. So we put the LED projector can be placed on the bed up to the ceiling projection, at this time the size of about 40-50 inches or so, the effect should be good, you can replace the bedroom bedside tv!

The past two years LED projector is developing rapidly, with the development of technology of the projector, the projector further tends to be small. Ultra portable projector due to the small size of the people's lives to bring a lot of convenience, welcomed by the people. In this condition, many projector manufacturers have attached great importance to the development of the small size of the projector, and scrambling to produce a kind of ultra portable projector with LED light source. At present, various manufacturers including Samsung, MITSUBISHI, Toshiba, and other companies have launched the Pulier using LED for ultra portable projector light source, they are using DLP technology, using 3LCD technology, but they have a common characteristic is that they are very small in size, only slightly larger than the palm of your hand very convenient to use.

Samsung P310 projector Moco projection screen demonstration in the IS CHINA 2007 concern

Pulier, from the beginning of last year, Toshiba in the domestic market the LED projector, aroused the concern of many consumers. In April this year, 31 friends of Tyco held in Beijing IS CHINA for the first time in the domestic exhibition of Samsung's LED projector P310. Become a major focus of IS CHINA 2007. Then at Cobo, Samsung LED projector continues to be a high-profile show, a time to become a hot topic in the market projection. According to Samsung LED projector China agent 31 friends of Beijing Thailand said that they are currently facing the country to carry out large-scale investment, the hope of the LED projector can expand more city around the country, let the users to enjoy the wonderful fun LED projector.

Advantages and disadvantages of LED projector:

Since LED projector more and more popular, so here we come together and find out LED projector.

LED also known as light-emitting diodes, English Light Emitting is the abbreviation of Diode, this technology starts early application in the fields 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 generally reach more than 10000 hours.

Projector using LED light source has the following characteristics: 1, extraordinary life, almost do not need to consider how long the problem; 2, electricity, almost do not need to consider the problem of electricity; 3, ultra portable, where to put in place, especially in the use of the battery; 4. The price is acceptable

Disadvantage: their brightness is very low, but also unable to cope with the business and education of typical application, can obtain the practical luminance level has become the key technology of LED light source. The author thinks that the LED projector is currently not completely replace the technical conditions of the living room TV, after all only in black environments in order to get good results, but the development of science and technology is fast, with the development of technology, may soon be used on a large scale in the living room.

What are the technical advantages of LED light source projector

The application of LED light source, in the projector, the main significance is that opens up a new path for the miniaturization. Due to the small size of the LED light source, and has many advantages of display technology, it is more suitable for the development of compact projectors and even the original, so that the user's projection more portable and free". LED for projection lighting, not only increases the service life, but also changed the structure of the projector, due to reduced cooling demand, and shorten the optical system, so the quantity of heat and noise have better performance. LED light source at present, the main application and integration of small projection and the original pocket two minicomputer projection products, integrated small projection original made independent models, with its main equipment such as mobile phone, digital camera, notebook computer integrated with micro display battery can image projection about A4 or standard letter size, convenient screen sharing with others. Pocket pocket projector is a complete independent model, compact and lightweight, one hand can easily pick up, easy to carry, can be placed in the package, the future direction of development is business applications. The utility model has the advantages that the utility model can be used for both AC and DC, the projection screen can be larger than 17 inches, and the brightness of the screen is between 15 and 200 lumens.

Two LED projection masterpiece

Introduced today we choose two LED projector is the second generation of products are Samsung, second generation and second generation of MITSUBISHI P310 mini projector mini projector PK20. The second generation of LED products than the first generation of product brightness has improved, in some of the performance characteristics of a more
