Generation 2 occupying the Market - Resolve laser LED mixed light source

Talking about a new projector light source, we must first think of LED, then and only then can the laser light source. However, the most recent technology, is the laser light source LED mixed light sources, and I was very surprised that there is a difference. In fact, it is now the latest laser LED mixed light source is the first generation 2 technology in 2010, and the first-generation hybrid light source technology makes a big difference.

Laser Projector light souce

For the area, the projector lamp usage, consumption, and later became the largest problems in the fields of engineering, and ultra-high brightness of the projector works as a Warcraft general, because of the light bulb brightness and life, each Warcraft projector bulb is "eat" the demons. Research and development of new light sources of the initial purpose is very simple, and that is in fact in order to obtain a long-life light source, overcome lived in traditional light sources. LED as a solid-state light source, the new hope, new direction in the new light source markets. The benefits are many LED gamut, wide, long life and low heat, low power consumption. But the fatal flaw LED similarly, countless people in the industry have been disappointed, brightness is too low. At this stage the most bright LED light source, the brightness of 1000 lumens.

LED Light theory

Putting aside the issue price, and this 1000 lumens of brightness can be achieved only about 2000 low-end model of the brightness level, and the brightness is too low, the color and the effect is very difficult to function properly, which means that it is difficult to meet user needs. The pre-increase LED brightness, is rather difficult, facing challenges: A 3, changing material, the cost is too high, and technology is not mature; B template changes, architecture, and increase the number, size and cooling is not easy to control; C to change package forms at this stage, there will be no break. These are the 3 development LED mountains, and there are many details of the problems have emerged in LED, the further development of the non-completion.

Not to force the LED under conditions of scientific research institutions, and many complaints have been transferred to a more promising, technical charm more powerful laser light source. This development is also difficult: the control problem has been solved, directional challenges overcome, and the energy density of the problem has been resolved, but there are still so many follow-up questions. Laser as a light source using non-all the characteristics, advantages, but is used as the light source, all the characteristics are weaknesses or shortcomings. Finally, in low-cost, highly pure form of color overcome the characteristics, has been unable to overcome.

When we was proud of his time, and some experts predict that the hybrid light source. Combined with two large light source, the technical characteristics of a light source, use the superior colors LED characteristics, combined with the brightness of the laser, laser light source LED Meryl Streep. Mixed light sources, in the strict sense is not new technology, but on a range of new applications, as history's great innovation was in fact from breaking.

The first LED and Laser Light theory

　　

Talk about a hybrid light source, the Laser is more concerned about, with the endless curiosity and yearning. Laser is also used for laser, is a transliteration of the English language; results for the term by Light Amplification Stimulated Emission Radiation of, to a certain extent, the laser, has been translated more closer to intent and transliterations. The laser characteristics, can be summarized for targeted, high-energy and high stability, which enables all interested is the energy density of high-light feature.

The secon LED & Laser Projector lamp light source

In the novels, and movies of the laser technology, the projector field, use of the laser technology is to be controls to the light source. There are two laser, a modern laser technology is primarily in the former Soviet Union scientists Nikolai Brasov in 1960 invented the semiconductor lasers, can be characterized by energy, laser pens, CD-ROM drive, CD player, the laser, laser light source device such as this are derivative.

Hybrid technology, it's like synthetic material, it is important that the mixture is light.

The first generation laser LED mixed light source of the word is relatively straightforward and maximum laser high-light, so that their bodies to group 1 + 1 blue laser group red LED blue laser, which derived from the color wheel. The first generation hybrid light source technical characteristics: 1 , relatively simple, you can make thin, ultra light model. 2, the blue laser applications, significantly reducing costs. 3, equal brightness relative to the product of the traditional light sources, more than 40% power savings. 4, the green is not natural. The blue laser energy is too strong, and the limitations of the color wheel, color was not ideal, and the Green is also mixed with the large number of Blu-ray.

　

The first 2 generations mixed LED laser light technology, compared with other lighting techniques better. Collection of more than one light source, as much as possible the technology Advantages Disadvantages has weakened

First, let LED mixed light sources, the advantage of color light and laser light source combined with the advantages of high-light. And that we are all familiar with LED light source, laser technology has dramatically increased the projector brightness, but the color cannot be avoided. The color saturation LED higher brightness, but too low, and the laser light source brightness, color is not satisfactory. Since the media publicity, LED light source with the power-efficient, high-efficiency, high color saturation is the substantial positive publicity, and disadvantage is completely submerged. The brightness LED lift, it is virtually not done; the task depends on the color laser printing, and laser wavelength depends on the active substances, the light, it is not easy to change colors and the facade is color stable, negative is that we have here is a emphasis on the color problem.

The first 2, at the same time balancing the energy of the light source LED laser light source and the high energy consumption. The light source and LED low power, low-intensity laser, high brightness and brings with it a high-energy-consuming. At this stage, traditional light sources in the projector to achieve the peak brightness 40,000 lumens, the laser light source engineering projection of peak brightness to 50,000 lumens, and LED peak brightness light source of products for only 1000 lumens.

The first 3, the hybrid light source technology upgrades. Laser LED mixed light technology, there are a total of 2 generations. Took 1 red LED + blue laser, color wheel will be blue-laser is divided into blue and green. Took 2 red + blue LED LED + blue laser, color wheel will be blue-laser turns green.
