Stage lighting design and configuration: The lighting is set for all-around three-dimensional distribution. Including surface light, top light, backlight, and sidelight in the depth direction.
1. Design of surface light system
The surface light is mainly used to illuminate the performance area at the front of the stage, and it plays the role of front lighting for the performers on the stage, which is used for character modeling or to make the objects on the stage present a three-dimensional effect. The lights above the auditorium at a position where the ceiling and the stage curtain form an angle of about 45° illuminate the actors and the performance space from directly above the stage and play a frontal lighting role for the performers on the stage, but the stage surface light is in the performance. The stereo effect is weak.
Equipped with a high-efficiency backlight, there is no lens in front of the backlight, and the light completely relies on the spherical reflector behind to project the light emitted by the electric light source to the stage, with a long direct irradiation distance and a large light projection area. A large-diameter beam effect with soft edges and high brightness can be obtained.
In addition, a black center often appears in the center during dimming. To avoid the black center, a ring baffle is added to the center of the front end of the lamp. Generally, LEDs are used as the surface light for those with short heights, and PAR64, spotlights, and backlights are used as surface lights for those with higher heights.
2. Design of top light system
In addition to the role of the contour light, the top light in the color matching of large-scale singing and dancing costumes, the unique static light curtain, and the imposing effect formed by the running lights in the fast-paced pop music all add color to the performances.
The first top light is the lighting performance area connected with the surface light. In addition to the role of the contour light, the top light can also render the color atmosphere and enhance the modeling and lighting of the set space.
When the air height is relatively short, the LED series is used for the top light fixtures. Mainly play the role of lighting, color change, and create the atmosphere of the stage performance. Due to the relatively large power consumption of conventional lamps and the feeling of baking, they are now gradually replaced by LED lamps, which can be used with moving head light and beam lights.
Moving head light (pattern) function: The moving head light moves through the X and Y axes to achieve the functions of color change, patterning, strobe, etc. It has a strong sense of movement. It is the preferred lighting equipment for stage lighting in the world.
Beam light function: the beam sense is particularly strong, and the occasion is used in explosive scenes.
LED moving head light: It can provide RGB color mixing and a comprehensive color mixing effect, and the color is pure and rich. It is widely used in large-scale variety shows and entertainment venues for color rendering effects. Sufficient heat dissipation space and a unique heat sink design can quickly dissipate the heat of the LED, and with good ventilation performance, the heat on the heat sink can be completely discharged from the lamp body, so that the temperature of the lamp can be kept below 60°C.
3. Backlight system design
The light projected from the reverse direction of the stage (such as top light, bridge light, etc.) can outline characters and scenes, enhance the sense of three-dimensionality and transparency, and can also be used as a specific light source. Backlight plays a very important role in shaping the effect and layering of characters or stage settings.
When the air height is relatively high, the backlight is used for the top light fixture.
The function of the backlight: it has the characteristics of a long throw, high illumination, and hard light quality. To highlight the silhouette effect of people and scenery.
When the air height is relatively short, the LED series is used for the top light fixtures. Can be used with moving head light and beam light.
4. Design of sidelight system
Auxiliary lighting illuminates the actor's face and enhances the level of the set.
When the air height is relatively high, spotlights and backlights should be used for top light fixtures.
When the air height is relatively short, the LED lamp series is used for the top light fixture.
The role of other auxiliary equipment:
The role of the chase light: The light position required from the auditorium or other positions is mainly used to track the performance of the actors or highlight a certain light, and is also used for the host. It is a feature of stage art and plays the finishing touch effect.
The role of the fog machine: It is the most commonly used type of stage equipment. The smoke emitted by the smoke machine is used to create a smoke atmosphere in the scene environment. As the smoke drifts, it can form a cloud effect and smoke atmosphere, and then cooperate with other stages. Lighting equipment to achieve the stage effect required by the scene.
The role of bubbles: simple operation, safe design. Easy to move around the stage. Shooting colorful bubbles under the effect of lighting is like being in a fairy tale world.
