The full-scene lighting of the theater stage and the auditorium is to centrally control the stage lighting and the auditorium lighting with DMX512 signals, extending the stage lighting to the auditorium, creating a new and passionate stage environment for the interaction between the stage actors and the audience.

The traditional theater stage lighting and auditorium lighting are two independent systems, and the stage lighting is a stage lighting system based on DMX512 control, which is dedicated to stage performances. The auditorium lighting is a lighting system, which is dedicated to the lighting of the auditorium, and does not participate in the stage performance.

With the continuous improvement of the demand for performing arts, the continuous development of related science and technology, and the continuous integration of various related industries of theater design, we tried to carry out the innovative design and construction of the lighting system in the newly built theater Beijing Private Huijia School Performing Arts Center, realizing the industry's first full-scene lighting system for the theater stage and auditorium.

The lighting of the auditorium in the theater is controlled by DMX512, and the following problems need to be solved:

First of all, the lighting on the theater rooftop, to meet the needs of ordinary normal lighting before and after the performance or during the meeting, because in this state, the audience hall is very bright, the appearance of the light must be perfectly matched with the acoustic decoration of the audience hall, and it is a dual-purpose lighting and stage function, in the state of pure lighting, the color spectrum is natural light, the height of the theater is very high, the brightness needs to be very large, the projection angle is small, and it is muted, so the power is very large, there is a heat dissipation problem, this kind of light is not available in the market, it needs to be customized. In order to solve the above problems, we customized a high-power DMX512 par lamp, which does not need a fan to dissipate heat and achieve silence, and at the same time we use 6 colors of red, green, blue and white plus double yellow channels, and the use of double yellow channels is to increase the brightness of natural light when pure lighting is used. Due to the large volume of the lamp, the appearance is not good-looking, based on the above considerations, for the acoustic decoration, we have adopted a small distribution group of the top of the auditorium acoustical reflectors layout, leaving a gap between the acoustical reflectors, and hiding the large top lighting in the gap of the acoustical reflectors, which can only let the light beam shine out.

The second is the selection and layout of other lights in the auditorium. In addition to the lights on the rooftop, there are also lights on the walls, lights on the top of the first floor, and lights on the overhangs of the second floor. The wall lighting includes the left and right walls and the back wall, and uses 3-inch crystal downlights. The top of the first floor is lit with 5-inch frosted glass downlights, and the eaves on the second floor are self-made rectangular lights. All of these lighting address codes are single light single numbers, and together with the headlights at the top, the spacing between the up, down, left, right, front and back is the same, which is convenient for the gaffer to compile a rich scene.

The above four lights are static lights, in order to improve the effect, we set up 8 electric tracks in the speaker room at the left and right ends of the stage, and installed 8 computer lights, 4 on the left and right. These 8 computer lights can shine on the big roof of the auditorium, bringing a more perfect dynamic lighting scene effect to the auditorium.
