At present, domestic lighting companies have developed rapidly in recent years. Great progress has been made in the quantity and variety of lamps, performance functions, manufacturing processes, quality levels and testing methods, but there are also unclear and blindly positioned product functions of some companies. Production and other issues worthy of attention.
1. Lack of awareness of intellectual property rights, price advantages are no longer obvious
The technical barrier of professional lighting is low. The main component is the computer light, which can be assembled according to different requirements of customers. The technology is basically the same as that of foreign lighting. Therefore, in the past few years, my country's lighting exports benefited from ample labor and cheap raw materials. However, with the accelerated development of the world economic integration process, we will inevitably face the challenges of international technical barriers, product patent protection, continuous improvement of market rules, etc. This will lead to development for some companies that have weak R&D technology and rely on imitation. It will be difficult. Standardization of the lighting industry, proprietary intellectual property rights, core competitive technologies, and national brands have become one of the most pressing topics in the industry.
On the other hand, after the financial crisis and inflation, the price advantage of the stage lighting industry is no longer obvious. Rising raw material prices and rising labor costs have caused manufacturing costs to rise by about 20%. However, with a general increase of 20% in costs, product sales prices cannot reach a 20% increase. This aspect forces my country's lighting export-oriented enterprises to transform from labor-intensive to technology-intensive and knowledge-intensive. Exporting countries are also facing some adjustments.
2. "Green Stage" puts forward new requirements for LED
The country and the entire society pay great attention to environmental protection, which has caused more and more companies to invest in the trend of low-carbon environmental protection. On the one hand, they improve equipment, improve production management, reduce waste of resources, and strive to ensure the quality and stability of lighting products. Sex. On the other hand, the use of LED light sources to replace the original high-power bulbs, and technical research on LED lighting products in line with stage performances.
As a green light source, LED has the advantages of high efficiency, energy saving, safety and perfect interpretation. But as a stage light source, perfect stage lighting function and performance are the most important. LED still has some problems to overcome in these aspects. The calibration life of the LED is 50,000 hours, and the lamps that can be used to the calibration life are relatively rare, and the light will decay quickly if it is not handled well. Different from the fixed light distribution of ordinary lighting fixtures, the light of stage fixtures is variable and can be adjusted, which is reflected in the distribution of light intensity, the shape and color of the spot. At the same time, it must have good color rendering, suitable and stable color temperature, and good consistency.
Since LED has not entered the field of stage lighting for a long time, only stage lighting users and a small number of manufacturers are concerned. In the past, the focus and related measurement data were mostly concentrated in the white light part. There is no involvement of color light, and no unified measurement has been introduced. standard.
In the photometer, the LED does not perform very well. For stage lighting, only measuring parameters are not enough, and subjective evaluation is required. An experienced lighting engineer is required to conduct subjective evaluation of light effects, including indicators such as light uniformity, chromatic aberration of light edges, and image distortion. When LED lamps are used on the stage, they need to obey the arrangement of the lighting engineer and make the technology serve the effect. This is a new requirement for LED lamps on the special occasion of the stage.
3. Combination of lighting technology and art. It is an inevitable trend for enterprises to master product application technology
With the advancement and development of science, light no longer plays a purely role in lighting. Both the theater stage lighting and the stage lighting for various displays or outdoor performances have undergone earth-shaking changes. The design and operation of stage lighting increasingly reflect the importance of the integration of technology and art.
Computer software for lighting design will continue to develop, which will eventually allow the designer to dominate his “visual” technology in a completely artistic “interactive” way. Today's lighting software only provides designers with assistance in design, drawing and paperwork. Future design software will be able to use "touch screen" and "voice recognition" functions. The intelligent control of the stage lighting system has begun to take shape.
Keeping pace with the development of stage lighting technology is the growth of stage product application technology. Some large domestic companies have accumulated experience in lighting product application in related projects.
They can design lighting control, special effects equipment and effect monitoring system solutions according to different scenes required by the stage, which has gone beyond the old idea of simply selling products. Choosing to work with the performing party to complete the lighting design plan of a work and a party, provide design ideas, and provide service and technical support, will undoubtedly become another powerful bargaining chip in addition to the product in the corporate bidding process. Of course, this is a big test for the strength of the company. It not only requires products with stable and reliable quality, but also requires high-quality design and on-site operators.
4. The era of comprehensive digitalization of stage lighting is coming, and the market demand for computer lighting will increase year by year
With the rapid development of digital technology in all walks of life, the field of professional stage lighting will gradually enter the era of comprehensive digitalization. At present, large-scale outdoor performance activities in China: professional lighting equipment used in large and medium-sized private concerts and indoor large and medium-sized stage plays (including studios), such as digital dimming consoles, computer light consoles, and digital silicon boxes , Computer effect lights, computer dyeing lights, follow spot lights, computer color changers, lasers, etc., most of them use digital control.
At present, computer lamp technology is in the era of digitization and networking, and users’ requirements for safety, stability, scalability and ease of use are also increasing. Portable, multifunctional, intelligent, and information management integration has become the user’s Pursuit and first choice. In the studio or performance venue, all lighting operation control equipment can be connected to the controlled equipment through a network workstation. Use TCP/IP Ethernet network technology, or use a combination of TCP/IP Ethernet and traditional DMX control technology to control the entire lighting system.
The successful application of technologies such as networked lighting, networked control equipment, networked management software, automatic alarm system, multi-network integration, and sound and light synchronization in some recent large-scale projects at home and abroad has brought new business opportunities for professional lighting companies. In the domestic professional computer lighting market, the demand will continue to increase year by year.
5. Holographic projection technology will become the "new favorite" on the stage in the future
With the development of science and technology, consumers' requirements for display effects are particularly prominent. The strong sense of space and perspective of holographic projection technology is the most attractive part of this technology. It is expected to become the ultimate display solution beyond the current 3D technology. In addition to entertainment applications such as stereoscopic movies, television, exhibitions, bars and KTV, holographic projection technology can also be used in many fields such as microscopy, interferometrics, projection lithography, military reconnaissance and surveillance, underwater detection, etc. The prospects are undoubtedly very impressive.
Throughout the history of the stage, the success of stage performances is all integrated with the progress of technology. Mankind has transitioned from the age of phonograph, record, and radio to the age of MV, TV, and the Internet. Nowadays, stage technology has been able to combine virtual and reality to allow people who cannot be present to perform together with real actors. All this is due to technology. charm. The holographic projection technology subverts the traditional stage acoustic and optoelectronic technology, and it brings people the dream three-dimensional experience, just like the wide application of LED displays on the stage, it will also become the "new darling" in the lighting stage technology industry in the next few years. .
6. High-end technology research and development lags behind the international level. School-enterprise cooperation becomes a talent introduction channel
The threshold of stage lighting technology is low, and there is no strong technical requirement to enter this field. Most of the R&D companies engaged in stage lighting in my country are small and medium-sized enterprises, and the core technology companies are still few. LED technology, which is currently popular as a trend, also originated from abroad. The core technology, process and related rules are controlled by foreign companies. There are very strict technical barriers and patent cross agreements. Chinese companies need a lot of related technologies to develop related technologies. Manpower, material resources and resources, without core technology in hand are the weakness of domestic professional lighting companies.
To change this dilemma, we must first start with the fundamental “talent”. Fortunately, many Chinese enterprises have begun to attach importance to the introduction and training of technical talents. Judging from the employment positions provided by employers, in addition to graduates in dance, music and other majors, many units have a relatively large demand for talents in stage art setting design, lighting and sound control, field affairs and stage supervision, and ticketing. Many companies not only rush to select talents, but also sign agreements with colleges and universities to jointly build training bases to institutionalize future school-enterprise cooperation.
