LED and laser which is the next generation of projection light source?

With the rapid development of the projection industry, the light is always a hot topic in the indispensable projection equipment, feeling from the consumer viewing to the cost of the manufacturer, light source development speed is directly related to the current projection technology real progress. In the face of the current market, manufacturers for the choice of light source is still very important, the projection of the light source is also quietly in progress. Today, we're going to talk about two hot spots, LED and laser.

In recent years, LED's attention is in the volatile period, the last 5 years is the best time for LED. The laser technology, from the date of birth has been a hot spot, but the future will only become more and more fire. Laser can replace LED, is an inevitable trend, but in the short term completely replace the LED there are still some problems to be solved. Among them, the controversial issue is basically concentrated in the gamut and brightness.

Laser can exceed LED, because the color gamut is wider, in fact, is not complete. Purely from the color gamut, the white LED is smaller than the standard color gamut, and the tricolor LED is only slightly higher than the standard range. Because of the limitations of technology, color gamut is only an idealized mathematical model, in reality, often do not meet the requirements. Because at this stage, the laser can be controlled only a few bands, failed to cover all, so the color gamut is not complete. Similarly, LED is also the case.

Brightness is still the focus of choice

In the new light source, the real advantage of the laser over the LED that is brightness. LED projector can only reach 1000 lumens brightness, and the brightness of the laser is much higher than it. From the moment the performance of the product on the market point of view, pure LED projection, there is still a certain advantage in the color gamut, but in terms of brightness is definitely lost in the laser projector. The world's first sale of laser projectors, brightness can reach 2000 lumens, but also the rise of space; and at this stage the brightest projector, you can reach tens of thousands of lumens.

It is undeniable that all light-emitting devices are hot, and the impact of heat is to reduce the use of life. At this stage, most of the laser light source in the normal mode of operation can reach 10000 hours of service life, in the energy saving mode can reach the service life of 20000 hours. According to the existing data, the laser light source in 5000 hours after the beginning of a significant brightness attenuation, and to the brightness of 14000 hours after the decay of 40%, but there are still nearly 60% of the brightness can be used normally. Compared with the traditional light source 2000 lumens of light bulbs, energy saving mode of life limit of 6000 hours, the advantages of laser technology in the service life will be highlighted.

Laser technology as a projection light source, is the future development trend, but in the short term can not completely replace the LED is also a fact. But we still believe that, with the development of technology, laser light will soon be popular in the projection industry, then will lead to the display of the technology revolution, thereby subverting the traditional display areas.
