Can the LED projector of the mini projector be turned off?

LED highlight the source of light to high-end configuration projector, has always been a hot topic in the industry. Traditional ultra-high pressure mercury lamps have no technical advantages in all fields. At present, it is only a matter of cost and maturity that allows the traditional bulb source to continue to survive. With the continuous development of new light source technology, the future bulbs will gradually become embarrassed in various fields. In the high-end field, laser light source has developed for three or four years. In 2015, laser light sources have made great progress. All brands are pushing high-end laser projectors. Can the LED light source of the mini projector be reversed? The LED projector has been brewing for several years. From the initial brightness of 50 lumens, it has reached the average level of 700 lumens, and even some of the larger LED projectors are still challenging the brightness of 1000 lumens. It can be said that the development speed of LED light source is not slow. But this light source is also a lot of problems. At present, most of the light source is applied in the field of micro projector, and the problem of high fever, low brightness and high cost has become an urgent problem. The laser light source is developing at a faster speed. In fact, the positioning of the micro projector itself is also very awkward. As a consumer product, the size of its user base has not been very large. After all, the proportion of the household market in the entire projector market is relatively low. The mini projector is actually a branch of the home projector. Narrow development channels in itself, so that the micro projector can not become a strong hotbed of LED light source growth. The 3500 lumen new plan needs to be concerned about why laser sources are developing faster. In fact, in this field, the demand of Engineering projector is bigger, so the carrying capacity of technology is stronger. The price of the projector is expensive, and there are many demands in the market. Whether it is a large project or in the field of movie projector, laser products have very good demand. The miniature projector is considered by many people to be a "plaything". There is no real market demand, which makes the development of LED light source somewhat weak. Traditional light sources will be eliminated, so the development of LED light source needs to find a new hotbed, that is, 3000 to 4000 lumen market. This market is actually the largest market now. Because the brightness of LED light source is not enough and the cost of laser source is too high, the market is mainly the market of traditional bulb light source. Of course, many manufacturers try the laser light source + Phosphor mode, but the brightness of this light source can achieve the brightness of the demand, but the screen is always biased. So it has never been the mainstream of the industry. Now it seems that this hybrid light source is a transitional technology. The three color LED high light source can meet the needs of the new market, so how to innovate in this light source? However, as Hitachi launched the 3500 lumen brightness business education projector, and BenQ and Optoma launched the three primary colors LED 4K projector, showing that LED has achieved a bright new solution. Although the cost of the scheme is still relatively high, there is no doubt that it has demonstrated the potential for development in the 3000 lumens sector. LED light source has many advantages, such as long life, pure color, stable use and so on. These advantages make LED light source an important force in the projector field. Although in the competition with laser, it has lost its advantage in the high-end field. But in the traditional 3000 lumens field, laser miniaturization has the technical difficulty, and the LED light source is the first to realize this possibility. At present, how to reduce costs has become the key to enter the LED market. 2016 is also the critical period for the development of LED high light source. The LED highlight will become an important configuration of the 3000 lumen high-end models.
