The prospect of LED light source in projector market

As everyone knows, the most important part is the projector bulb, mostly projector lamp life of more than 2000 hours, with less than a year's time will need to replace a light bulb, while the price of more than 2000 yuan, resulting in the use and maintenance of the high cost of projector. Lamp life is short, the price is expensive, making it difficult to enter the projector. The past two years, with the rise and application of LED light source technology, projector lamp life to tens of thousands of hours, the projector users no longer need to worry about replacing the bulb.

Light emitting principle of LED light-emitting principle and incandescent lamp and gas discharge lamps are different, the energy conversion efficiency of the LED light source is very high, the energy consumption can theoretically reach 10% of incandescent lamp, energy saving effect compared to the LED fluorescent lamp can also reach 50%. Energy saving effect is remarkable, which is of great significance to promote low carbon. LED can also be combined with solar cells, energy saving and environmental protection. It is understood that the projector with LED bulb life in 50000-60000 hours, even if the use of 5 hours a day, then you can use the 6000 day, that is, more than 16 years. This is conducive to the user's acceptance and acceptance of the projector, the probability of purchase behavior will be greatly improved.

Whether it is high-definition, or micro projector, the LED light source gives a high expectations. Compared with the traditional light source LED light source has three obvious advantages: small volume, which belongs to the cold light source, the radiating module can be greatly reduced in line with the development trend of miniaturization; color gamut is high, make up for the shortcomings of traditional light source color loss more, more in line with the requirements of hd. So we can see the world's top 500 companies, such as Samsung, LG, ACER, DELL, BENQ, HP and other products have been selected as the main market orientation of LED projector products.

Recently, Samsung launched F10M, many advantages, LED will increase to 1000 lumens brightness and break the world record at the same time, also opened up a new application field of LED projection products, so many manufacturers see the projection of LED light source in the future prospects of the.

According to media reports, the well-known manufacturers HP has also joined the ranks of the launch of micro projector, HP AX325AA 0.45 inch DLP, the brightness of 100 lumens, only 800:1 on the ratio of red / Green / blue LED light source, the resolution of SVGA (800x600), the projection distance of 2.6 meters, 15 to 60 Inch projection size. The most important thing is the weight of only 0.42 kg, the use of D-Sub output, but the projector is the end of the special 30pin connector, the use of this projector available for up to ten thousand hours.

LED light source has many advantages, such as small size, low power consumption, long service life, low heat dissipation, wide color gamut and so on. But LED light source also has its shortcomings, that is not enough brightness. Brightness is one of the biggest problems plagued the popularity of LED projectors. Although the market has a brightness of 1000 lumens can reach more than LED projector products, but this brightness is still far from enough for daily applications, especially commercial applications. So manufacturers still need to continue to try to break the technical bottleneck, unremitting efforts to create a broad prospect.
