Stage lighting is an important part of the performance space. It is based on the development of the plot to carry out a comprehensive visual stage lighting environment lighting design for the characters and specific scenes required, and purposefully reproduce the design intent to the audience in a visual image. Artistic creation. The spatial modeling of characters and plots should be considered comprehensively and systematically, rigorously following the modeling rules, and making good use of modeling methods.

　The prospect of the stage lighting system in the future is very exciting. After the advent of incandescent lamps, the technological changes in stage lighting systems began with the emergence of ellipsoidal reflector (Leko) lamps in the 1930s. In the 1960s, the emergence of SCR dimmers caused a fundamental change in the development of stage lighting systems. At present, automated lamps and computer lights (first appeared in the 1970s) are setting off another revolution in stage lighting technology.

　 Computer software for stage 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 stage lighting 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.

　 However, looking at the domestic market, we can often hear sales staff and customers say: "We use imported XX..." Why is the domestic stage lighting relatively backward in people's eyes?

1. Reason analysis

1. Backward concept　The concept of backwardness involves many aspects. On the manufacturer’s side, some people think that the technology content of lamps is low, and they will do it at a glance. You don’t need to invest in development and just copy them. Others think that there is no market for high-end products, and the development investment is large and the risk is high. Others have a weak concept of implementing standards. Turn a blind eye to various technical standards and norms; even have a low legal concept, pretend to be inferior, fake and inferior. From the perspective of users, some theater troupe leaders think that lighting can only handle the performance, and they are unwilling to invest more funds to update equipment or purchase high-end lamps; some theater managers reject high-maintenance, complex, high-performance lamps and light leakage. It doesn't care whether it is a problem or not, just satisfied that there is no problem with the performance, just change the light bulb less; there are a few lighting personnel who are used to old lamps and are unwilling to accept new things and new products.

2, the design force is weak　　Some lighting manufacturers have few or no designers, and their professional level is low. They often hire people temporarily when developing new products. Although the real lighting experts may be invited, they do not understand the stage, and they do not understand the function of the lighting on the stage, and they may not be able to design a lighting that is welcome on the stage. In addition, they leave after the product is developed and cannot improve or upgrade the product.

3. Insufficient investment in lamp development and lack of technical reserves　 In recent years, some insightful domestic manufacturers have begun to invest large amounts of capital to develop some new products, but for a country with a vast territory like China, it is still far from enough. Driven by economic interests, short-sighted behaviors are not uncommon, and those who are willing to invest heavily and make technical reserves are even rarer.

4. Low-end market impact　 At present, many troupes and theaters are financially struggling, especially the large number of small and medium troupes and prefecture-level theaters. Therefore, low-cost, low-performance products still have a broad market. Manufacturers are vying for the low-end market, and price wars are inevitable. The cost of the product can be saved by one point and never five percent. The material is thinner, the wires are thinner and shorter, and the process is less. The quality of the product is thus wiped out bit by bit. For high-end products such as Yangchun Baixue, there are very few people, and their efforts are not thankful. In addition, the manufacturers' own capabilities are inherently insufficient, and they are comfortable in the low-end market.

5. The manufacturer’s management level is not high　 Domestic lighting factories are mostly small enterprises, among which there are many private enterprises. Although a few have passed ISO9000 and other international certifications, there are still many hand-workshop-style production and family-style management, and there is a lack of modern enterprise system construction.

6. The impact of foreign advanced products

The entry of advanced foreign lamps has brought new technologies and new ideas to the Chinese people, but also impacted the domestic market. At present, high-end products can be said to dominate the world with foreign products. Many large theaters built in the past two years, as long as economic conditions permit, all use imported lamps. Some domestic manufacturers are unable to compete with foreign brands and can only abandon the development of high-end products, which has a certain negative impact on the development of domestic lamps.
