How to configure LED lamps in all directions in theater auditorium lighting design


Traditional lamps or civilian lamps in the lighting design of theater auditoriums cannot meet the lighting needs. The configuration of lamps should fully consider factors such as high color rendering, accurate color temperature, safety and durability, good heat dissipation, flexibility and convenience, etc. LED lamps are the mainstream trend. The lighting configuration and layout should meet the requirements of meeting-oriented and various evening performances. How can the luminaires be arranged flexibly so that they can be arranged reasonably and meet the needs of functions such as meetings and performances? As long as each lamp on the stage of the theater auditorium is arranged in an all-round way and connected in series through signals, the integrity of the lighting system can be realized.

The surface light can be a 200WLED video spotlight with an illuminance of 10-12 meters, which can illuminate the face of the character very brightly and very shiny; the 200WLED imaging light can reach a distance of 15 meters. The light is distributed according to the projection distance to ensure that the projection effect of the surface light lamp is achieved, and the light spot is uniform and the illumination is consistent.


Arrangement and projection method of surface light in theater auditorium:


Vertical projection: make uniform effect under the stage performance area;


Cross projection: Enhance the brightness of the center area and depth of the stage;

The requirements of the lamp are similar to that of the surface light. The projected beam cannot overflow beyond the proscenium. The slap light can use LED video spotlight, LED video back light.


Arrangement and projection method of lamps and lanterns:


Slap is an auxiliary light for face light, which is used for character modeling;


The color atmosphere of the stage can be rendered from one side or both sides. The outer light and the inner light are cross-projected, and a larger projection range can be obtained;

Arrangement and projection method of lamps and lanterns:


The shooting distance of the side light is from near to far, and the projection angle is from near to far. There are many changes. The modeling light from one or both sides can emphasize and highlight the contour of the side. It is suitable for embossing, characters and other volumetric objects. effect. Unilateral light can show a stronger effect of yin and yang. The double-side light can express the plywood light with individual characteristics, but the light ratio of the front auxiliary light and the side light needs to be adjusted to obtain a more complete modeling effect.
