3、 Fusion extends stage space
”Stage space is not only a useful physical space for actors to perform, but also an aesthetic space for aesthetic perception through symbolization (Hu Miaosheng, aesthetics of stage design).
Stage artists have been working hard to create this kind of space with setting and lighting. TV variety show uses two-dimensional TV pictures to show multi-dimensional stage space. The integration of light and scene is conducive to the extension of TV variety show stage space.

1. The effect of light on scenery Jing is Ben. Light is spirit. In addition to creating a specific stage atmosphere, the light dyeing of the scene. It can also enhance the sense of stage space through the contrast of warm and cold colors. At the same time. The contrast of light and shade levels and the shadow created by different light angles can extend the stage space feeling. This is also the re creation of landscape space by light.
2. Create void through beams and dots. On the stage of drama. It's easy for the human eye to accept the black area of the stage setting "because the human eye has a wider adaptability to light than the TV camera. But in the TV variety show, lighting designers are very concerned about the style of the art scene - "closed" or "open". Generally speaking, open stage scene lighting is easier to create void. Through the effect of smoke, light beams and light spots interpenetrate between the "black areas" of the scene. It not only makes the TV picture more transparent, but also meets the needs of TV picture composition. Otherwise, the "black hole" will appear "dull" on TV lens. How to make the stage space of TV variety show combine virtual and real. This is what designers of both sides need to think about together. Art design should not blindly pile up scenery, lighting design should not blindly show themselves, need a clever combination of the two.
Art scene is not a complete work, only through the combination with light, actors' performance and other comprehensive factors can reflect the value of art scene, that is, we must consider the possibility of the existence of other elements. So is lighting design, which is the difference between pure art and art design. For example, the stage design of CCTV's "music and painting fashion" provides an "8" type step. In the middle of the background, there is a computer lamp and a tube. Video devices on both sides and irregular star lights on the back. Under the effect of smoke, accompanied by the rhythm of music. The beam of the computer light forms a flowing "Scene", and the movement of the beam produces a sense of perspective. The light spot of the star light participates in the composition of the picture in the close range, and makes the stage space open and far-reaching in the long range.

4、 Integration to enhance the stage decoration
The function of TV art in TV variety show is not only thematic but also functional. There is also an important feature - decorative, the pursuit of a beautiful stage scene. It's the consensus of every designer, and it's also the audience's demand for TV visual effects. We seek new rhythm and modern consciousness of TV art design from architectural art, decorative art and advertising art. The emergence of new lighting technology and new stage materials. It also enriches the modern decorative sense of stage art. The combination of light and scenery enhances the decoration of TV variety show stage.
1. With the development of lighting technology, lighting devices with various colors and shapes appear. In addition to the common color leather lamp band and neon lamp that can be shaped at will, the new cold grade lamp tube can change color through the lamp body, which can be combined with the art scene to hook the edge. You can also design decorative patterns. Self luminous lighting on the TV screen decorative strong, decorative sense of modern, but when using small areas of lighting to pay attention to the luminous brightness can be higher. The brightness of large area lighting should be low. Because the scene lighting is too bright, it is easy to cause the character light too dark. It can block the light source, and use the halo effect to make the light spot softer. At the same time, the lighting can also flash through the effect controller combined with the rhythm of music. The shape, color and brightness of the lighting should not be too messy, but should be unified in the atmosphere of the whole stage.
2. Landscape dyeing. The stage of the 21st century is a century of lighting and materials. The development of new materials and new lighting technology has enriched the expression techniques of stage art. Svoboda, a famous Czech stage artist, said: "using light and projection to replace the setting of pigment painting is the future.". Compared with the fixed color of the scene film, the light color is more varied, and the light color is more beautiful in TV imaging than the painting color, and the combination with the scene is more decorative. Light for the scene of the dyeing is divided into forward projection and back projection. It is required to have proper light position and light angle when casting, so as not to hit the actors as much as possible while ensuring full dyeing. And art designers have foresight on the reflective degree of the film material. The lighting design can adjust the light angle according to the camera position to avoid the reflective highlights entering the camera. When the camera is inverted, the light should have enough projection space and choose the appropriate projection angle. The art designer should pay attention to the transparency of the scene, not only to meet the brightness of the scene when it is inverted, but also to avoid the "pass through" of the light source and the "pass through" of the scene keel, Today's transparent materials, such as plexiglass, sunlight board and light box cloth, have different choices in terms of transparency. You can also use sulfuric acid paper or soft paper on the scene to soften the light spot, so that the scene can be dyed evenly and softly.
The combination of light and scene should be an important standard to judge the creation of TV art and lighting. Only light and scenery are integrated and cooperated sincerely. Only in this way can we create a stage scene of TV variety show full of vitality and sense of the times.
