What is a conventional light?

Conventional lights are a series of lamps that must be used on the stage.

Ten types of conventional lights:

1. Spotlight: It is one of the most widely used main types of lights in stage lighting. Currently, there are 1KW and 2KW on the market, with 2KW being the most widely used. It irradiates concentrated light, and the edge of the spot outline is relatively clear, which can highlight a part, and can also enlarge the spot to illuminate an area. As the main light source of the stage, it is often used for surface light, slap, side light and other light positions.

2. Soft light: The light is soft and well-proportioned. It can highlight a certain part without any harsh light spots, making it easy to connect several lights. Common ones are 0.3KW, 1KW, 2KW, etc. It is mostly used for close-range light positions such as column light and flowing light.

3. Reflective light: It is a reflective lamp, which is characterized by hard light quality, high illumination and long range. It is an economical and efficient strong light. Commonly used There are mainly 0.5KW, 1KW, 2KW, etc., with 2KW being the most used.

4. Astigmatism lamp: the light is diffuse, uniform, and has a large projection area. It is divided into sky-dispersed astigmatism and ground-discharge astigmatism. The common ones are 0.5KW, 1KW, 1.25KW, 2KW, etc., which are mostly used for canopies. Illumination can also be used for general lighting of the theater rostrum.

5. Modeling light: The principle is between the following light and the spotlight. It is a special lamp mainly used for modeling projection of people and scenery.

6. Footlights (also called strip lights): soft light and wide area. Mainly used for lighting and coloring in mid-scenes and netscapes, and can also be used as auxiliary surface lighting at the entrance of the stage.

7. Beam column lamp (also known as downlight): currently widely used, such as PAR46, PAR64 and other models. It can be used to illuminate characters and scenery in all directions. It can also be installed directly on the stage and exposed to the audience to form a light array, which serves the dual functions of stage decoration and lighting.

8. Projection slides and awning effect lights: can form an overall picture on the stage awning, and various special effects, such as: wind, rain, thunder, electricity, water, fire, smoke, clouds, etc. .

9. Computer light: This is a smart lamp controlled by DMX512 or RS232 or PMX signal. Its light color, light spot and illumination are better than the above conventional lamps. It is a kind of smart lamp developed in recent years. , often installed in surface lights, top lights, steps behind the stage, etc., and the colors, shapes, pictures, etc. during operation can be programmed for operation. Due to the different power levels, the use on the stage should be different. Generally, low-power computer lights are only suitable for use in dance halls. On the stage, low-power computer light lines and spots are often blurred by stage spotlights, backlights, etc., so special attention should be paid to their selection.

10. Follow spotlight: It is a stage lighting fixture. It is characterized by high brightness and the use of lens imaging, which can present a clear spot. By adjusting the focal length, the virtual spot can be changed. There is a movable light bar, which can easily change the color, and the lamp body can move freely, etc. There are many varieties on the market, and the indicators are marked in different ways. Those based on power are: 1KW tungsten halogen light source, 1KW dysprosium light source, 1KW metal halide light source, 2KW metal halide light source, etc. There are also light chasing based on distance. Lights (light intensity and illumination at a specific distance), such as 8-10m follow-up light, 15-30m follow-up light, 30-50m follow-up light, 50-80m follow-up light, etc., and are functionally divided into: For mechanical follow-up lights, the focus adjustment, diaphragm, and color change are all done manually; the other is the computer follow-up light, whose focus adjustment, diaphragm, color change, and color temperature adjustment are all done automatically by pushing and pulling electrical appliances, so in When choosing, you must carefully select various indicators.
