Stage lighting system and peripheral equipment

1. Various lighting control methods

spotlights, backlights, heaven and earth row lights, imaging lights, etc. with a dimming table for control.

Computer lights, dyeing lights using computer lights console control.

Adjustable three-color soft light (cold light) with a dimming console for control.

non-adjustable three-color soft light (cold light) with cold light control panel for control.

color changer with color changer console to control (now largely eliminated).

2. The principle of the role of the dimmer table

There is a major luminous flux regulator (commonly known as the "main push") to regulate the overall level of the entire system. Each lamp is equipped with an independent regulator (commonly known as "sub-push") to regulate the single unit.

3. lighting system, what are the hanging methods and application range?

Studio net height of 3M within the application of fixed type is more appropriate;

Studio net height of 3M-7M application slide rail type is more appropriate;

studio net height of 7M and above, the application of an electric boom mechanical system is more appropriate.

multi-purpose hall depending on the situation.

Theatre, auditorium, concert hall, and banquet hall are generally high, mostly for the application of electric boom mechanical system.

The above situation needs to be combined with the owner of the investment situation.

4. The role of color changer

Used for lighting to play a linear dimming and change the light color role.

The digital dimming color changer is divided into three parts: the box, color change control, and dimming control. The box body before and after the opening of the hole contains the left and right color paper rollers and its drive motor, fan, power supply board, signal decoding board, dimming module, and color paper rollers on the reel for color change with color paper.

5. DMX512 signal

DMX512 is the United States Institute of Dramatic Technology (USITT) developed specifically for data communication between the stage lighting console and dimmer protocol standards, and later expanded to computer lights, color changers, and a variety of stage equipment control fields. dmx512 is the main content of the data protocol for communication to make provisions, which are directly related to the signal transmission cable, the main content are.

1. communication interface using the EIA-485 standard common in computer communication, its electrical characteristics fully refer to the provisions of EIA-485.

2. DMX512 protocol signal transmission rate of 250kbps.

6. The function of the stage lighting system

① make the stage picture clearer: so that the audience can see what or certain corners of the stage the audience can not see (presentability).

② strengthen the effect of stage performance: in line with the needs of the plot, so that the background appears natural, the development of the plot until the setting, hint and induce the role, regulate the atmosphere (actors, audience).

7. The use of stage lighting principles.

① intensity (refers to the brightness of the light): there must be enough light so that the audience can see the color, appearance, and details.

② distribution: including the use of light distribution and shot to the stage direction distribution, the main body must be different from the supporting cast and background, and obviously (color) can be brightness difference.

③ color: rely on color paper, computer color mixing and other ways to meet the needs of the plot.

④ change: according to the needs of the plot, so that the color, brightness, and movement of the light change.

The specific use of the stage lighting process, in reducing a light source before, should be ready to enhance the next light source, in addition to the special needs of the plot. Try to avoid black field, so as not to affect the work of the actors and actresses.

8. The basic configuration of the stage lighting system

(1) System.

(2) for the command and scheduling of the above lamps and lanterns' color ratios and luminous brightness, often use the light distribution and dimming table for the performance of lighting effects to regulate control.

Light distribution table: according to the plot needs to configure the stage layout and other parts of the color of light.

Dimming table: there is a major luminous flux regulator (commonly known as the "main push") to regulate the overall level of the entire system. Each lamp is equipped with an independent regulator (commonly known as "sub-push") to single regulation and control.

9. Stage lighting system by position, how to call?

Face light, ear light, top light, column light, side light, backlight, foot light, heaven and earth row, chasing light, computer lights.

10. Stage special effects equipment

① strobe lights: can send a very strong and constantly flashing white light, disco commonly used lamps.

Use precautions: strobe lights may promote the onset of certain epileptic patients, in the use of attention to observe the presence of the above-mentioned symptoms of personnel.

Use no more than once a half hour; strobe frequency shall not be higher than 6Hz (that is, 6 times per second flash.)


② fog machine (also known as dry ice effector): can produce smoke close to the ground. Before use will be dry ice into the machine with hot water in the container to produce CO2 gas expansion along the mouth of the machine sprayed out, forming a thick fog 0.5-1m from the ground.

Precautions for use: Since dry ice is not convenient for transportation and preservation, and the high concentration of CO2 has adverse effects on people and animals, it should be used with caution. (Now there is more liquid nitrogen)

③ Smoke machine (also known as hair smoke machine): the main component of the glycol smoke oil as a smoke agent, through electric heating to produce a slightly fragrant gray-white smoke (not close to the ground) to fill the room, to the human body harmless, cheap, widely used, pay attention to the temperature of electric heating.

④ bubble machine: motor blender inside the bubble liquid, by the fan blowing bubbles.

Note: bubbles fall onto the stage, causing slippery, unsightly and easy to make people slip and fall. Must choose the appropriate special bubble liquid, otherwise easy to block the machine or pollute the performance stage.

⑤ Other: firecrackers: pay attention to the launch angle, confetti falling on the lamps, and lanterns are flammable. (Now more with tapestries flame retardant type)

Snowmachine: pay attention to slippage and pollution of the stage.

11. Stage lighting effects equipment related to national standards

1, strobe lights: frequency less than 6Hz (6 times per second flash). Not more than once every half hour before use

2, laser lights: should not be directly on the human body, in particular, direct or reflected the human body its value: wavelength between 380 = 780nm

3, ultraviolet light: wavelength between 320-380nm

4, the stage illumination of each region: 

① The farthest audience to the performance

① the farthest audience to the center of the performance area distance of less than 8m

② the farthest audience to the center of the performance area distance greater than 8m
