To do a good job in the configuration of professional stage lights, we must first understand the common light levels of stage lights ↓
Surface light: the light projected onto the stage from above the audience, which is mainly used to illuminate the front of the characters and spread the whole base light.
Slap in the face: The light obliquely projected from the stage on both sides of the podium is divided into two layers, which mainly assist the surface light, strengthen the facial lighting and increase the three-dimensional sense of people and scenery.
Column light (also called side light): The light projected from both sides of the platform entrance is mainly used to illuminate both sides of people or scenery to increase the three-dimensional sense and outline sense.
Top light: The light projected onto the stage from the top of the stage is divided into one row of top lights, two rows of top lights and three rows of top lights from front to back, which are mainly used for general lighting of the stage to enhance the illumination of the stage, and there are also many fixed-point lighting of scenes and props, which are mainly solved by top lights.
Backlight: the light projected in the opposite direction of the stage (such as overhead lights, bridge lights, etc.). ) can outline people and attractions, enhance the three-dimensional sense and transparency, and can also be used as a specific light source.
Bridge light: the light projected onto the stage at the overpass on both sides of the stage, which is mainly used to assist the column light and enhance the three-dimensional sense. It can also be used in other directions where the light level is inconvenient to project, and can also be used as a specific light source.
Footlight: the light projected from the platform in front of the stage to the stage, which is mainly used to assist the surface lighting and eliminate the shadow formed by the surface lighting on people's face and chin.
Light of heaven and earth: The light projected from the crown up and down is mainly used for the illumination and color change of the crown.
Streamer: located on the streamer stage on both sides of the stage, it mainly assists the bridge light and supplements the light on both sides of the stage or other specific light.
Light-chasing: The light level required from the audience or other positions, which is mainly used to track the performance of actors or highlight a certain light, and also used for the host. It is a close-up pen of stage art, which plays the role of making the finishing point.
In addition to the light position, the light color changer is also very important. It is an indispensable instrument for the current stage configuration. At present, there are two main color changers on the market: mechanical color changers and computer color changers.
Stage mechanical color changer: it is the mainstream product in the mid-1980s and 1990s, with simple design and low price, and it is nearly eliminated at present.
Stage computer color changer: it is a new type of color changer developed in recent years. It adopts the international standard DMX-5 12 signal output, which can be controlled by a special console or connected to a computer dimmer. With the characteristics of multi-mode, high precision, large capacity and long control distance, it has become the mainstream product of color changer in the market at present.
Finally, the lighting control equipment ↓
Analog dimmer: analog dimmer technology is adopted, and the output signal is 0- 10V one-to-one output. The general analog dimmer has simple design, few controller circuits and poor dimming curve, but the market price is low and it is easy to learn and master. It was the mainstream product from the late 1970s to the mid-1990s. There are three, six, nine, 12, 18, 24, 60, 120, etc. Each power is 8KW, but there are 2KW, 4KW, etc. The number of paths is mostly integrated machines, and the number of roads is mostly split machines.
Digital dimmer: adopting phonograph technology, it is DM5 12 digital signal. Digital dimming meter is easy to use (especially in large loop), and its dimming function, backup function, grouping function and dimming curve are better than analog dimming meter, and its performance and price are reasonable, which is very popular with users. Common roads are 12, 36, 72, 120, 240 and 1000, which are 2KW, 4KW, 6KW and 8KW respectively.
After knowing the position, characteristics, control equipment and color changer of the lamp, the subjects now have a preliminary understanding of stage lighting. Now, according to their own characteristics, the size of the use scale and the simplicity of using lamps, the correct use scheme can be designed according to local conditions.
