Replacing traditional light sources: analysis of current status and trends of laser projectors

In recent years, engineering projectors have become the first choice for more and more public display solutions due to the wonderful applications in various large-scale events such as the Olympic Games, World Expo, Asian Games, and the unparalleled large-screen visual effects. Since its development, engineering projectors have also been widely used in exhibitions, control rooms, virtual simulation and digital signage markets, and will be used more in creative display solutions in the future. The rapid growth of market applications will inevitably lead to a more segmented and repositioned engineering projector market to meet different customer application needs. Especially in the past two years, new light source technology has sprung up. Who will compete with the future in the engineering projector market?

The brightness output of the engineering projector is above 5000 lumens. Among them, the range of 5,000 lumens to 10,000 lumens is the main model in the engineering projector market, with the highest market share and large demand. According to statistics, the sales of engineering projectors in the global market between 5000 and 10,000 lumens account for more than 91% of all engineering projectors, and China even exceeds 96%. Typical characteristics of engineering projectors include high brightness, interchangeable lenses, stable and reliable performance, and meeting various complex application requirements. Typical applications include medium and large conference rooms, exhibition displays, control rooms, etc. Engineering projectors over 10,000 lumens are aimed at unconventional high-end markets. Due to high brightness but low overall resolution and high selling prices, the demand is relatively small, and their main applications include stage, theater and so on.

With the increasing demand for high-brightness engineering projectors in the domestic market, today's engineering projector market has also undergone new changes in light source technology. At present, it is divided into traditional light bulbs, laser light sources and hybrid light sources (laser + LED). Among them, the hybrid light source has not exceeded 4000 lumens, mainly involving manufacturers including Casio and Panasonic. Because the brightness is too low, it can not be used in the engineering field.

As a traditional bulb light source that you are more familiar with, although it has a very good price competitive advantage at around 5,000 lumens, it is still limited by the rapid brightness decay and the short life of the bulb. The traditional lamp engineering projector with more than 5000 lumens, with the sharp increase in brightness, the life of the lamp is also shortened, generally around 2000 hours. Although there are some dual-lamp technologies, but if 24 * 7 hours of operation, the attenuation of the bulb is more obvious, and the use limitations are still many. In addition, the price of the bulb as high as 1,000 yuan also makes the later use of the cost burden increased, comprehensive Cost-effective.

The emergence of laser light source technology has solved the above problems well, with a high comprehensive cost performance and a wider range of applications. In recent years, brands including Sony, Panasonic, Barco, Christie, and AVANZA have all joined in, and have contributed to the development of laser light sources. However, at present, the products launched by Sony, Panasonic and other brands are all below 4000 lumens, and the brightness of laser light source products launched by brands such as Barco and Christie are above 30,000 lumens. In the engineering market with the largest demand of 5000 lumens to 10,000 lumens, there is currently only AVANZA, and it has also launched the world's only mass-produced GreenOmni series laser engineering projector products. Their emergence makes many traditional engineering projectors face the difficulties.

The brightness of the AVANZA GreenOmni series laser engineering projector is between 5000 lumens and 8000 lumens, and the integrated design of the fourth generation laser light source and light source light machine is adopted, which solves the problems of the previous three generation projectors and the brightness decay is very slow . Taking a traditional 6000 lumen lamp projector as an example, the lamp only has a life of about 2000 hours, and the brightness of the lamp quickly drops below the nominal value of 70% at the initial stage of use. The same nominal brightness, GreenOmni provides far higher The visual brightness of the traditional lamp projector.

Compared with the traditional lamp projector, it has multiple color modes: demo, highlight, high color and other modes, and improves some color gamut by sacrificing brightness. GreenOmni laser engineering projectors break the convention. High brightness and wide color gamut can coexist. Under the same color gamut or compared with the high color mode of traditional projectors, the output brightness of the laser light source is more than 50% higher, which can be far greater than The color space of the traditional light source is more than twice the color performance of the lamp projector, and the color saturation reaches the extreme, which can most realistically reproduce the colorfulness of nature.

AVANZA GreenOmni series laser engineering projectors have a relatively narrow spectral range, with more than 98% concentrated in the visible light range. The photoelectric conversion efficiency is high, so the power consumption is greatly reduced when the same brightness is reached. Since there is almost no invisible light and excess heat radiation, the components inside the projector are working under ideal conditions, and there are few factors that cause failures, and it is not prone to failures.

Traditional projectors can only be installed with 360-degree horizontal selection and vertical installation with a very limited angle (generally plus or minus 15 degrees). GreenOmni laser engineering projectors are not limited, and can be installed 360 degrees horizontally and horizontally and 360 degrees vertically. Can be creative, without any limitations. Through the specially designed rotating mechanism, the projector can even become a moving head light of the stage, projecting a multi-resolution picture with high resolution and high brightness.

Due to the use of laser light source technology, the life of the machine has reached more than 20,000 hours, and it has stable brightness and color output. Since then, the projector no longer needs to frequently replace the lamp. The most important thing is that it is no longer necessary to frequently adjust the projector to ensure the effect of multi-machine fusion. Coupled with the sealed optical path design, the DLPTM chip, prism, and laser light source are all sealed to prevent the intrusion of dust and other particles that affect the quality of the image, and the life of the machine is longer.

In addition, with the efforts of engineers, the energy radiated by the GreenOmni laser engineering projector is equivalent to the laser pointer used in the conference. GreenOmni passed the test according to the IEC / EN 60825 specification and obtained the certificate of Class II laser products issued by TUV, which is a very safe device. The first-generation RGB laser projector is a Class IV laser product and is subject to strict safety regulations.

According to statistics from relevant agencies, domestic sales of high-end engineering projectors reached 61,627 units in 2013, and sales in 2014 are expected to be close to 80,000 units, a double-digit growth rate, highlighting the strong demand for bright engineering projectors. At the same time, it also means that users' requirements for products will continue to increase. The emergence of laser engineering projectors can not only bring high quality and perfect experience to users and markets, but also greatly reduce the cost of later use. As a professional enterprise, AVANZA's GreenOmni laser engineering projector will surely trigger the display technology revolution, and will also provide customers with more innovative and complete solutions. The laser light source will also become a "potential stock" in the future engineering projector market, especially in the face of the ever-changing engineering projection market demand, taking into account the cost-effective characteristics, the dominant position of the laser light source will continue to highlight in the future, and is expected to lead the future trend.
