Types and characteristics of stage lights Precautions for the use of stage lights
In the field of lighting, in addition to indoor lighting and outdoor lighting, there is also a kind of commercial lighting. There are many types of commercial lighting lamps. Stage lights are one of them. Generally, few people know about stage lights. What are the types and characteristics? What are the precautions for the use of stage lights? Let's learn about it with BENWEI LIGHTING.
Types and characteristics of stage lights:
1. Spotlight:
It is one of the most widely used main lamp types in stage lighting. At present, there are 1KW and 2KW in the market, and 2KW is the most widely used. It illuminates concentrated light, and the edge of the spot contour is relatively clear, which can highlight a part or enlarge the spot to illuminate an area. , As the main light source of the stage, it is often used in light positions such as face light, slap light, and side light.
2. Soft light:
The light is soft and well-proportioned, which can highlight a certain part without a hard spot, and is convenient for connecting several lights. Common ones are 0.3KW, 1KW, 2KW, etc., which are mostly used for close light positions such as column light and mobile light.
3. Back light:
It is a reflective type lamp, which is characterized by hard light quality, high illuminance and long range. It is an economical and efficient strong light lamp. The common ones are mainly 0.5KW, 1KW, 2KW, etc., and it is used at 2KW. most.
4. Astigmatism light:
The light is diffuse, uniform, and has a large projection area. It is divided into sky astigmatism and ground astigmatism. The common ones are 0.5KW, 1KW, 1.25KW, 2KW, etc., which are mostly used for skylight illumination, and can also be used for general lighting of theater rostrum.
5. Modeling lights:
The principle lies between the follow spotlight and the spotlight. It is a special kind of lamp, mainly used for the projection of characters and scenery.
6. Footlight (also known as strip light):
The light is soft and the area is wide. It is mainly used for lighting and coloring to the middle and net scenes, and it can also be used as auxiliary surface lighting at the proscenium.
7. Beam light (also known as downlight):
At present, it is widely used, such as PAR46, PAR64, etc., which can be used to illuminate people and scenery in all directions. It can also be directly installed on the stage and exposed to the audience to form a light array for the dual role of stage decoration and lighting.
8. Projection slides (also called projection slides) and sky curtain effect lights:
It can form an overall picture on the stage canopy, and various special effects, such as: wind, rain, thunder, electricity, water, fire, smoke, clouds, etc.
9. Computer lights:
This is a smart lamp controlled by DMX512 or RS232 or PMX signal. Its light color, spot and illuminance are better than the above conventional lamps. It is a kind of smart lamp developed in recent years and is often installed in surface light, top light, and behind the stage. Steps and other positions, the color, shape, diagram, etc. in operation can be programmed to run programs. Because of the different power levels, they must be used on the stage differently. Generally, low-power computer lights are only suitable for use in dance halls. Low power on the stage Computer lighting lines and spots are often eliminated by stage spotlights, return lights, etc., so pay special attention to the selection.
10. Follow spot light:
It is a stage lighting lamp, characterized by high brightness, the use of lens imaging, can present a clear spot, by adjusting the focal length, the spot can be changed from virtual to reality, there is a movable diaphragm, the color can be easily changed, and the lamp body can be freely rotated. Now on the market There are many varieties, and the way of marking indicators is different. Power-standards such as: 1KW tungsten halogen light source, 1KW dysprosium light source, 1KW metal halide light source, 2KW metal halide light source, etc., there are also distance-based follow-up lights ( The light intensity and illuminance 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 functionally divided into: mechanical tracking For light, the focus, light barrier, and color change are all done manually; the other is a computer follow-up light, whose focus, light barrier, color change, and color temperature adjustment are all done automatically by pushing and pulling electrical appliances, so when choosing All indicators must be carefully selected.
Stage lights
The above is a brief introduction about the types and characteristics of stage lights. I believe that after the above introduction, everyone will have a further understanding and understanding of stage lights. Of course, stage lights also have precautions during the use of stage lights. Pay attention to the use of stage lights. What are the issues? Let's take a look at the following introduction:
Precautions for the use of stage lights:
1. Precautions for the use of stage lights:
When the bulb is at normal temperature, do not push it violently, which may cause the bulb to burst or the bulb's tungsten wire to fuse.
1. Most of the bulb glass shell is uneven in thickness, so uneven heating will also occur. If you push the bulb sharply, the bulb glass shell will heat up instantly, and the bulb cannot withstand such a large temperature change. It's easy to burst.
2. When the bulb is not in use, there will be some water molecules attached to the bulb. These water molecules will cause the bulb to be suddenly turned on and bring greater stimulation to the bulb.
3. Turn on the bulb suddenly, the bulb will produce an instantaneous impact current, it is easy to melt the tungsten filament of the bulb.
2. Use and operation skills of stage lights:
1. Before turning on the bulb, you can push the fader up a bit to make the bulb slightly brighter, and let the bulb slowly warm up to make it evenly heated and evaporate the water molecules on it. After waiting a few minutes, it will turn on. One point, open it step by step.
2. When turning on the power, you must strictly follow the correct operating sequence. Reversing the sequence will affect the life of the bulb.
3. When turning on the bulb, the action should be light to avoid damage to the tungsten filament in the bulb.
4. When replacing the bulb, it is recommended to wear special gloves to minimize direct contact with the bulb, which will not only make the surface of the bulb not clean enough, but may also cause the bulb to burst.
5. Don't forget to install the protective net cover, it can provide people with safety guarantee when some lamps and lanterns have accidents.
6. Some heat source lamps should not be too close to combustibles to avoid fire.
7. The power of the light to be installed cannot exceed the rated power.
8. Do not cause three-phase imbalance when connecting the load.
