      In recent years, with the control of the energy policy and the development of science and technology, governments to vigorously promote the new technology and high efficiency, energy saving, environmental protection products, under the guidance of government policy, cultural career improving increasingly prosperous and domestic manufacturer of technology innovation and development, the stage lighting industry vigorous development.

      Stage lighting is also known as stage lighting. Stage lighting can help the audience directly see all scenes or part of scenes on the stage, make the scenery on the stage look realistic, create a sense of time and space on the stage, shape the external image of the stage performance, and better show the writer's creative intention and artistic level of the work.

      To build the stage space and time environment and artistic effect. Usually, the color, movement and intensity of the lighting should be strictly plastic and controllable. The overall artistic effect needs two aspects to realize. One is basic lighting, can see the actor's performance and scenery image, on the other hand is the performance effect, according to the plot change background, story background, atmosphere adjustment, special application.

      Lighting has spotlights, floodlights, projection lights, pursuit lights, digital flat soft light, imaging lights, lens reversion and so on. Current power ranges from 10w-1000w. At present, all LED lighting technologies are used, and more drives are adopted. Low-cost PT4115, MT7201C+ (40 V1A), TI company LM3409HVMY, LM3414HVMR (total positive). There are also the most cost-effective DIODES AL8843, AL8863 (60V, 3A+) conventional applications, such as PT4115, MT7201C+ single board applications are 4-72, the current of the current of the current of the LED bead used for stage lighting is generally large, such as LM3409HV, AL8863 high current chip will be more popular.

      The lighting control system consists of a power control board, a dimmer, and a console. That wants to control effectively allocate all lamps and lanterns, produce artistic effect.Control the commonly used such as ST 32-bit MCU, STM32F103 is universal, the pursuit of higher performance can choose the M4 series, the general solution is to chip as the core of building, the stepper motor drive, the more general is ST L620X, STSPIN series with TI DRV88XX series, currently has domestic semiconductor manufacturers (CST) AT88XX series will also be able to meet customer demand.

      Market analysis

      Since the stage came into being, stage lighting has been an integral part of the stage. In today's industry informatization level continuously improve, professional lighting and stage audio equipment industry used more widely in the system, such as personal family club, business center, entertainment industry, the government, large conference YanChuTing, theaters, cinemas, shake the light show of shenzhen is expected after the spread of many cities in the world.

      Looking back at the supply and demand of domestic stage lighting market in recent years, shake head lamp, LED lamp and computer lamp occupy the top three positions alternately. In recent years, the construction of the Olympic Games, the world expo and the Asian games venues, the renovation of the old venues and the tens of thousands of performances each year have led to the rapid development of the performing arts market in various countries, which contains huge business opportunities. Today, with the continuous improvement of the application level of industry information, with the increase of residents' income, the level of consumption is also constantly improved. The majority of consumers spend more and more on public entertainment and artistic performances, which brings huge business opportunities to the development of audio and video industry from the perspective of demand. For example, the monthly shipments of MBI's LED drive are above 2KK, and the monthly shipments of TI's motor drive are also within the range of 800k-1.2kk, excluding the superposition of other models.

      At present, there are more than 7,000 enterprises in entertainment equipment industry in China, including 5,600 enterprises in professional lighting, audio and stage machinery industry, and about 1,500 enterprises in related fields and businesses. According to the analysis of the data of the latest national economic census, the total number of entertainment equipment enterprises in China increased by 33% compared with the results of the last census, and the number of core businesses (professional lighting, professional audio and stage machinery) increased by 26.1%. The total assets of the industry reached 140 billion yuan, and the main revenue reached 196.06 billion yuan.At present, China has become an important manufacturing base of lighting, audio and entertainment equipment products in the world, especially in the pearl river delta region, where more than 70% of the enterprises are gathered, accounting for about 80% of the total output value of the industry.

      According to the analysis of professionals in the industry, although the global economic instability is complex, the economic pace of developed countries such as Europe, the United States and Japan is also moving forward with difficulties, and the first half of 2018 also shows an economic downturn in China.

      In addition, in the construction of new towns in China, the upgrading and upgrading of public places, such as movie theaters, KTV package halls, concert halls, and performing arts activities, as well as lighting projects, China's lighting, audio and performing arts equipment industry is still showing a steady rise in 2018.
