At present, domestic lighting enterprises have developed rapidly in recent years, making great progress in the quantity, variety, performance, function, manufacturing process, quality level, and testing methods of lamps. However, there are also some issues that deserve attention, such as unclear product function positioning and blind production in some enterprises.
1、 Lack of intellectual property awareness, price advantage no longer apparent
The barrier to entry for professional lighting technology is relatively low. The main component is the computer light, which can be assembled according to different customer requirements. The technology is basically on par with foreign lighting technology, so in recent years, China's lighting exports have benefited from the favorable situation of abundant labor and cheap raw materials. But with the accelerated development of world economic integration, we will inevitably face challenges such as international technological barriers, product patent protection, and continuous improvement of market rules. This will make it difficult for some enterprises with weak research and development technology and relying on imitation to develop. Standardization, proprietary intellectual property rights, core competitive technologies, and national brands in the lighting industry have become one of the most urgent topics in the industry.
On the other hand, after experiencing the financial crisis and the heavy blow of inflation, the price advantage of the stage lighting industry is no longer significant. The rise in raw material prices and labor costs has led to an increase of about 20% in production and manufacturing costs, but despite a general cost increase of 20%, it is difficult to achieve a 20% increase in product sales prices. On the one hand, this forces China's lighting export-oriented enterprises to shift from labor-intensive to technology intensive and knowledge intensive. Exporting countries are also facing some adjustments.
2、 The 'Green Stage' puts forward new requirements for LED
The great concern of the country and even the whole society for environmental protection has led more and more enterprises to invest in the trend of low-carbon environmental protection. On the one hand, they improve equipment, enhance production management, reduce resource waste, and ensure the quality and stability of lighting products. On the other hand, replacing the original high-power light bulbs with LED light sources and conducting technical research on LED lighting products that are suitable for stage performances.
As a green light source, LED has the advantages of high efficiency, energy saving, safety, and perfect performance. But as a stage light source, the most important thing is the perfect stage lighting function and performance. There are still some challenges that need to be overcome in these aspects of LED. The calibration life of LED is 50000 hours, and it is relatively rare for lamps to reach the calibration life. If not handled properly, the light will decay quickly. Unlike the fixed distribution of light in ordinary lighting fixtures, the light in stage lighting fixtures is variable and can be adjusted, reflected in the distribution of light intensity, the shape and color of the light spot. At the same time, it is necessary to have good color rendering, suitable and stable color temperature, and good consistency.
Due to the short time that LED has entered the field of stage lighting, only users and a small number of manufacturers have paid attention to it. In the past, the focus and related measurement data were mostly concentrated on the white light part, without involving colored light, and there was no unified measurement standard introduced.
In photometry instruments, LEDs do not perform very well. Measuring parameters alone is not enough for stage lighting fixtures, and subjective evaluation is also necessary. Experienced lighting technicians need to subjectively evaluate the light effect, including indicators such as light uniformity, color difference at light edges, and imaging distortion. When LED lighting fixtures are applied to the stage, it is necessary to obey the arrangement of the lighting engineer and make technology serve the effect. This is a new requirement for LED lighting fixtures in this special occasion of the stage.
3、 The combination of lighting technology and art has become an inevitable trend for enterprises to master product application technology
With the progress and development of science, lighting is no longer solely used for illumination. Whether it is theater stage lighting or various exhibitions or outdoor performances, stage lighting has undergone earth shaking changes, and stage lighting design and operation increasingly reflect the importance of integrating technology and art.
The computer software for lighting design will continue to develop, ultimately allowing designers to dominate their "visual" technology in a fully artistic "interactive" way. The current lighting software only provides designers with assistance in design, painting, and paperwork. Future design software will be able to use "touch screen" and "speech recognition" functions. The intelligent control of stage lighting system has begun to emerge.
Along with the development of stage lighting technology is the growth of stage product application technology, and some large domestic enterprises have accumulated experience in the application of lighting products in related projects they have participated in.
They are able to 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 performers to complete the lighting design scheme of a work and a party, provide design ideas, and provide technical support for services will undoubtedly become another awesome chip in addition to products in the bidding process of enterprises. Of course, this is a major test of the strength of the enterprise, as it not only requires products with stable and reliable quality, but also demands high-quality design and on-site operation personnel.
4、 The era of comprehensive digitalization of stage lighting has arrived, and the demand for computer lighting market will increase year by year
With the rapid development of digital technology in various industries, the field of professional stage lighting will gradually enter the era of comprehensive digitization. At present, most of the professional lighting equipment used in large-scale outdoor performance events in China, such as square parties, large and medium-sized individual concerts, and indoor large and medium-sized stage plays (including studios), such as digital dimming tables, computer light control consoles, digital silicon boxes, computer effect lights, computer dyeing lights, chasing lights, computer color changers, lasers, etc., are digitally controlled.
Currently, computer lighting technology is in the era of digitization and networking, and users' demands for security, stability, scalability, and ease of use are increasing. The integration of portable, multifunctional, intelligent, and information management has become the pursuit and first choice of users. All lighting control devices can be connected to controlled devices through network workstations in the studio or performance venue. Using TCP/IP Ethernet network technology, or combining TCP/IP Ethernet with traditional DMX control technology, to control the entire lighting system.
The successful application of technologies such as networked lighting fixtures, networked control equipment, networked management software, automatic alarm systems, multi network integration, and audio-visual synchronization in some large-scale projects at home and abroad has brought new business opportunities for professional lighting enterprises. The demand for professional computer lighting in the domestic market will continue to grow year by year.
5、 Holographic projection technology will become the "new favorite" of the future stage
With the development of technology, consumers' demand for display effects has become particularly prominent. The strong sense of space and perspective of holographic projection technology is the most attractive aspect of this technology. It is expected to become the ultimate display solution beyond current 3D technology. In addition to entertainment applications such as 3D movies, television, displays, bars, and KTVs, holographic projection technology can also be applied in various fields such as microscopy, interferometry, projection lithography, military reconnaissance and surveillance, underwater detection, etc. Its development prospects are undoubtedly very promising.
Throughout the history of the stage, the success of stage performances has always been intertwined with technological advancements. Humanity has transitioned from the era of phonographs, records, and radios to the era of music videos, television, and the internet. Today's stage technology can now combine reality and virtuality to allow people who cannot attend to perform with real actors, all thanks to the charm of technology. Holographic projection technology overturns traditional stage sound, light, and electricity technology, and brings people a dreamy three-dimensional experience, just like the widespread application of LED displays on stages, it will also become the "new darling" of the lighting and stage design technology industry in the coming years.
6、 The research and development of high-end technology lags behind the international level, and the channels for introducing adult talents through school enterprise cooperation
The threshold for stage lighting technology is relatively low, and there are not too strong technical requirements to enter this field. Most of the research and development enterprises engaged in stage lighting in our country are small and medium-sized enterprises, and the enterprises that master the core technology are still a minority. The LED technology, which is currently popular as a trend, also originated from abroad. The core technology, process, and related rules are all controlled by foreign enterprises, with strict technical barriers and patent cross agreements. Chinese enterprises need a lot of manpower, material resources, and resources to develop related technologies. Without core technology in hand, it is a weakness for domestic professional lighting enterprises.
To change this dilemma, we must first start from the fundamental 'talent'. It is gratifying that many enterprises in China have begun to attach importance to the introduction and cultivation of technical talents. From the employment opportunities provided by employers, in addition to graduates in dance, music and other majors, many units have a high demand for talents in stage art and scenery design, lighting and sound control, venue management and stage supervision, ticketing and other aspects. Many enterprises not only compete to select talents, but also sign agreements with universities to jointly build training bases, institutionalizing future school enterprise cooperation.
