Flood Lights For Outdoor Stage
Stage lighting is an important part of the performance space. It is based on the development of the plot to perform a full range of visual environment lighting design for the characters and the specific scenes needed, and purposefully reproduce the design intent to the audience in an artistic way. The stage lighting allows the audience to have a better view There is no doubt that the stage lighting has a huge effect on the performance.
What are the requirements for lighting on the outdoor stage?
1.Lighting quality requirements:
It is not enough to use only the amount of light for visual satisfaction. Even with the brightness required for the performance, all performance intentions cannot be fully and accurately expressed. To cleverly distribute light or colored light according to the situation so that the performance is correctly performed, it is necessary to consider not only the amount of light but also the quality of the light.
2.Lighting level requirements:
There is no fixed mode for the stage illumination. Due to the variety of functions used in this multifunctional hall, the performance styles are different.
The lamp types are matched for the lighting engineers to choose, so that the average illumination of the stage> 1800LX, and the illumination of the stage performance area> 2500LX.
3.Glare limitation requirements:
In the stage of the place, in addition to the lighting arrangement, attention needs to be paid to the problem of glare. The projection angle of the beam of light should be controlled at 30-
Between 60 degrees, the optimal angle is 45 degrees. When the beam of light includes the audience’s eyes, it will cause a dazzling feeling to the audience.
The perception affects viewing. Due to the multi-directional nature of the light and the stage has a certain height, it is very close to the front audience, which is impossible for them.
Glare is generated, and when the actor is on the side of the stage, the nearby audience must look at the actor’s face at an elevation angle, which is contrary to the viewer’s view
The side lighting in the line direction may produce glare, so in the stage design-generally, for the edge of the stage, the inner lighting angle must be Raise to 55 degrees, the aperture should not exceed the knees of the audience in the first row.Principles to determine. In addition to direct glare, reflection glare caused by bright paint on the stage surface should be avoided.
4.Requirement of three-dimensional shape:
The reasonable use of lights should be used to obtain the three-dimensional effect of the directional lighting. The modeling lights can change the level of the performance area, or it can be strong and solemn. It can also be elegant, but it should avoid too many lack of brightness contrast. Diffuse light, but it seems helpless, and the direction should not be too strong, to prevent the shape of the plate, when the narrow beam of light collects too much shadows, the image interlacing will be messy and dilute the beauty of the shape, and at the same time, some lamps are retrofitted. Colorizer to increase the freedom of light changes.
5. color temperature and display requirements:
The determination of color temperature and display is very particular. Most lights have several different capacity options, and the color temperature directly affects the luminous rate. Long-term practice has proved that it is more appropriate to use stage lighting with a color temperature of 3200K.
Why choose floodlights for outdoor stage
What is a flood light
Floodlight, English name: Floodlight A floodlight is a kind of point light source that can illuminate evenly in all directions. Its irradiation range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. Flood light is the most widely used light source in the production of renderings. Standard flood lights are used to illuminate the entire scene. Multiple flood lights can be applied to a scene. In order to produce a better effect, the shooting bulb is installed in a large reflecting umbrella for use as a high-brightness diffused light source. Although it is indispensable for indoor lighting, it is also one of the light sources with good lighting effects for general amateur indoor photography. Floodlights are also called spotlights, spotlights, spotlights, and so on.
How flood lights work
Flood light is the most widely used light source in the production of renderings. Standard flood lights are used to illuminate the entire scene. Multiple flood lights can be applied to the scene to produce better results. Floodlight is the most widely used light source in the effect map. Multiple floodlights can be used in the scene to coordinate effects to produce better results.
Product Features of Floodlights
Under low current, the temperature rise of LED flood light is not obvious. If the ambient temperature is high, the dominant wavelength of the LED flood light will be red-shifted, the brightness will be reduced, and the uniformity and consistency of the light will be deteriorated. In particular, the temperature rise of the dot matrix and large display has a more significant impact on the reliability and stability of LED floodlights. So thermal design is critical. Floodlights illuminate objects uniformly from a specific point in all directions, and it is best to use them to compare light bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the range of the camera or inside an object. It is common to use many different colored floodlights at long distances in a scene. These flood lights can cast shadows and blend on the model. Because the range of the floodlight is relatively large, the effect of the floodlight is very easy to predict, and there are many auxiliary uses for this kind of light. For example, if the floodlight is placed near the surface of the object, it will be on the surface of the object Produces a bright light.
Specific reasons to choosing floodlights for outdoor stage arena
1.Environmental-friendly light source
LED is made of non-toxic materials. Unlike mercury in fluorescent lamps, which can cause pollution, LE can also be recycled. There is no ultraviolet and infrared in the spectrum, neither heat nor radiation, small glare, cold light source, can be touched safely, belongs to Typical green lighting source
2.Accurate irradiation angle, free adjustment of optical angle
The lamps are equipped with scale plates for easy adjustment of the irradiation angle. High-purity aluminum reflector, the most accurate light beam, the best reflection effect. The irradiation angle is accurate. LED flood light has the most accurate beam, the best reflection effect, symmetrical narrow angle, wide angle and asymmetric, and the illumination accuracy is also very high. It is in line with the lighting of the stage, which is used to chase and strengthen the three-dimensional sense of people and scenery. The lighting effect on the front side ensures the accuracy of positioning.
3.Multiple changes and color adjustment
The LED light source can use the three primary color principles of red, green and blue. Under the control of computer technology, the three colors can be 256 gray levels and mixed arbitrarily to produce 256 X 256 x 256 = 16777216 colors, forming a combination of different light colors. Variety of changes, to achieve a variety of dynamic changes and various images.
RGB color adjustment
Floodlight is controlled by a built-in microchip.In small engineering applications, it can be used without a controller.It can achieve dynamic effects such as gradation, jump, color flicker, random flicker, and gradual change. , Scanning and other effects. Meet the outdoor stage’s requirements for light diversity.
Led flood lights can be dimmed through different dimming schemes. You can choose TRIAC dimming, DALI dimming, 0-10v / 1-10v dimming to achieve LED dimming. Only need to select a dimming mode according to the parameters of the lamp, and then equipped with a suitable dimming power source or controller can achieve the dimming of the lamp. This feature of floodlights meets the special requirements of outdoor stage lighting.
4.Rugged and easy to maintain
The LED is completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. There is no loose part in the lamp body, so that
The LED is not easily damaged. Easy to maintain by replacing the bulbs by turning on the back.
5.higher light efficiency, less glare
Imported anodized aluminum reflector, low power consumption, power-saving LED power consumption is quite low, DC drive, ultra-low power consumption (single tube 0. 03-0. 06 watts), electro-optical power conversion is close to 30%. -Generally speaking, the working voltage of LED is 2-3.6V, and the working current is 0.02-0.03A; that is to say, the power it consumes does not exceed 0.1W, and the same lighting effect saves nearly 80% energy than traditional light sources. Imported anodized aluminum reflector with higher light efficiency and less glare.
6.Features of advanced technology and flexibility

It successfully integrates computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information product, is a “high-tech” technology of conductive optoelectronic devices, online programming, unlimited upgrades, flexible and changeable. Features. Typical green lighting source
7.Flexible power control
Specially designed high-light-efficiency, long-life gas discharge bulbs are used as the light source; when using dual-tube HPS lamps, they can be started and restarted immediately without cooling. This meets the flexible requirements of the outdoor stage for light adjustment. Floodlight start-up control meets the requirements of stage specificity. There are two ways to drive LED floodlights: it is a constant voltage source for multiple constant current sources, and each constant current source supplies power to each LED individually. In this way, the group is flexible, and all the way to the LED failure will not affect the work of other LEDs, but the cost will be slightly higher.
Based on the advantages of the above floodlights, floodlights are the best choice for outdoor stage lighting, and also the best choice for other major occasions. As one of the important products in the lighting market, its illumination range can be adjusted arbitrarily, and it can produce projected shadows on objects. Flood light is the most widely used light source in the effect map. “Standard flood light” is usually used to illuminate the entire scene without any specific range. The scene can be coordinated by multiple floodlights, which is one of the most important reasons for choosing floodlights for outdoor stages. It can illuminate highly diffuse, non-directional light instead of clear-cut beams, resulting in soft and transparent shadows. Stage lighting can provide a better viewing experience for audiences. There is no doubt that stage lighting is The performance has a huge effect.
Advantages of using floodlights on outdoor stage
Benefits of using floodlights on outdoor stages:
Developed to a friendly man-machine interface, intuitive and easy menu, stronger operability, low heat, super energy saving .It is understood that the lighting design of a medium-sized theater is 500kW to 800kW, and the annual lighting electricity consumption is more than 600,000 degrees. These disadvantages make green, energy-saving and safe stage LED lights gradually become the new darling of the stage. What kind of energy-saving effect can the stage LED light source achieve? LED stage luminaires are cold light sources and do not need to rely on heat to generate light. Energy saving ranges up to 70% to 80%. According to statistics, if the green lighting program is implemented in 100 theaters, it will save nearly 50 million kilowatt-hours of electricity, save 20,000 tons of standard coal, reduce 50,000 tons of carbon dioxide, and save electricity for 200,000 households for one year. In recent years, domestic LED performing arts lamps have developed rapidly and their applications have become increasingly widespread. In the National Grand Theater, the National Museum and other cultural venues, as well as large-scale performing arts events organized by the Olympic Games and Shanghai World Expo, LED performing arts lamps are put into use. The awareness of domestic manufacturers on stage lighting has also gradually increased, the power of domestic LED monomers has been continuously improved, and the color transition from three primary colors to full color can better meet the needs of stage performances.
What should be noticed when using floodlights on outdoor stage
Several considerations in the application of stage lighting during large outdoor performances. A large number of applications of decorative lights Decorative lights mainly play a role in setting the atmosphere. For the large number of point light sources, it is still important to pay attention to environmental protection and low carbon in the outdoor. Different color point light sources emit light and flicker, with different brightness and darkness, which can play the best embellishment effect on decorative objects. In this regard, LED flood light sources have unique advantages. LED flood light colors are applied in blue and white. Mostly. The temporary outdoor performance lights used by the performing arts lights are temporarily operable, because it is necessary to hurry to get quality. Some lights may be removed after this period of time, and the user group may not be a professional performance company or group, so most of them will choose to lease. They do not have high requirements for the lamps and lanterns, and they should not be very professional and easy to operate, and the price Concessions, use groups are concentrated among some students and young people. May also have smoke effects, fountains and so on. During the festival, due to the particularity of the use of lighting, the requirements for lighting are still relatively low. The main reason is that a decorative stage lighting is mainly leased. There is no special requirement for use. Just add care.
Trends of Outdoor Stage Floodlights Use in Future
in the future. Stage LED flood lights will definitely replace tungsten halogen lamps or gas discharge lamps, because it is greener, more energy efficient and safer. The heat from traditional stage lighting. The huge energy consumption is also the reason for the decline of tungsten halogen lamps or gas discharge lamps on the traditional stage. It is understood that the lighting design of a medium-sized theater is 500kW to 800kW, and the annual lighting electricity consumption is more than 600,000 degrees.
