The stage lighting industry market development trend forecast

Modern stage lighting designers put forward a new management concept of stage lights, where more than one function effect of different digital lighting equipment, such as digital dimming silicon box, digital color changer, light, color changer light effect of computer, digital machine, bubble machine, connected by a digital dimming control, a lighting engineer to control. DMX512 signal transmission system has been proved that the idea is feasible. Second, the world's first no one set of stage lighting control system, this system to fill the domestic blank, now provides the international leading. System consists of electronic audio recognition system, the lights of the song program control database and the timeline of editing software, supplement each other between the parts to be short of one cannot. Use is very convenient, optional songs on demand, the system immediately identify music melody, and adjust the corresponding types of corresponding lights to cooperate, and adjust the lighting drums flashing.
The neon technology
Relevant technical staff developed a remote installation of neon transformer, through the transfer of a copper core BV of withstand voltage 500 v power supply cord, transformer may be installed in dozens of meters or hundreds of metres distance tubes. The greatest characteristic of this technology, there are two: one, the transformer can be install to facilitate monitoring in the background, in one thousand the neon transformer malfunction, can change in a short time; Second, when one thousand a bright lamp fails, other lamp can light up. Using this technique, the application of neon lights on the stage to get a higher security.
The high frequency electrodeless lamp technology
Previous high frequency electrodeless lamp coupler in bulb cavity body heat is too big, cause the power of light cannot be higher than 165 w. 2.65 MHz oscillation frequency, electromagnetic compatibility index difficult to pass; Electrodeless lamp life of more than 60000 hours in theory, but the life of electrolytic capacitor has restricted the whole lamp. And now, already can be changed by electrodeless lamp power supply, using magnetic filter components to suppress and eliminate the conducted interference, abandon the use of electrolytic capacitors and other methods to overcome the above problems, make electrodeless lamp breakthrough development bottleneck, an important step to the higher realms.
The stage lighting industry development trend prediction
Along with our country culture career improving increasingly prosperous and domestic manufacturer of technology innovation and development, China's lighting industry vigorous development. According to incomplete statistics, the domestic lighting manufacturers have more than three hundred, mainly in guangdong area, accounts for about 70% of the country's total - 80%. In August of 2011, China entertainment technology association in guangdong province has carried out in the field of professional lighting technical report. Experts generally believe that the domestic lighting enterprises development quickly in recent years, in the number of lamps and lanterns variety, performance, function, manufacturing process, quality level, and made much progress in such aspects as detection means, but there are also some enterprises product function orientation is not clear, such as blind production concern.
(a) lack of intellectual property rights consciousness no longer obvious price advantage
Professional lighting technical barriers is low.
Its main components are amount, can be assembled according to customer requirements. Technology and foreign lighting technology flat, so a few years ago in China lighting exports thanks to sufficient labor cheap, cheap and good raw materials. But with the acceleration of world economic integration development, we will inevitably face the international technical barriers, product patent protection, the problem such as perfecting the challenge of market rules, it would have been to some weak r&d technology and self by mimicking the copied, even development will be difficult, the standardization of lighting industry, has its own intellectual property rights, core technology, national brand competition has become one of the most urgent topics inline.
On the other hand, after the financial crisis, inflation fell, stage lighting industry price advantage is no longer apparent. Raw material prices, rising labor costs, make the production costs have risen by about 20%, but in the case of costs rose 20%, the product selling price is difficult to achieve 20% growth. The bright light on the one hand, forcing the export-oriented enterprises from the labor-intensive to technology-intensive and knowledge-intensive. Exporting countries also face some adjustments.
(2) the corporate environmental responsibility consciously stage of "green" put forward new requirements to the LED
State and even the whole society to the attention of environmental protection, making more and more enterprises into the tide of low carbon environmental protection, they on the one hand, improving equipment, improve production management, reduce resource waste, lift the light product quality and stability. On the other hand, the use of high power LED light source to replace the original bulb, and LED lighting products in line with the stage of technical research.
LED as a green light source with high efficiency, energy saving, safety and the advantages of the perfect deduce at an organic whole. But as a stage lighting sound stage lighting function and performance is the most important. LED in these areas there are still some problems need to overcome. LED the life of calibration is 50000 hours, can use to demarcate life lamps and lanterns is very rare, processing is not good light will decay very fast. Different from general lighting lamps and lanterns light fixed distribution, stage lamps and lanterns of light is variable, and can be adjusted, reflected in the distribution of light intensity, light spot on the shape and color. Also have good color rendering, suitable and stable color temperature, good consistency, etc.
Because the time is not long in the field of LED into the stage lights, only users of stage lighting and a small number of manufacturers, in the past focus more focused on the white part, and the relevant measurement data for the colourful is not involved, is not a unified standard.
In the luminosity measuring instrument, LED performance is not very well. Stage light with the light of lamps and lanterns parameter measurement is not enough, must have the subjective evaluation, have the experience of lighting engineers have a subjective evaluation on photosynthetic efficiency, including uniformity, light on the edge of the color difference and deformation of imaging index. Applications in the LED stage light effect, the need to obey the arrangement of juicers, make technical service for effect, this is the stage for a special occasion LED put forward new requirements.
