Outdoor Creative Billboard Lighting Design
February 14, 2023
Outdoor creative billboards are in the outdoor natural environment. During the day, their effects can be displayed under natural light. At night, they are hidden in the dark and cannot display their content. Even in urban environments, other lights in the city are not enough to illuminate them . Therefore, at night, it is necessary to implement artificial lighting on the billboards, so that the advertising information can also play a role in the night. The lighting quality of outdoor creative billboards should grasp the following three aspects: 1. Reasonable illumination The illuminance must meet the standard, too strong or too weak light is not suitable. Excessive light not only consumes energy and equipment, but also produces light curtain reflection or blurred reflection, fogging the graphic layout, and even produces reflection spots, which make it impossible to see and harm the visual health of the viewing object. If the light is too weak, it can only have a viewing effect at a short distance, and it will not work at a long distance, and it will not have the proper publicity effect. To determine the appropriate illuminance also need to consider: 1) The properties of the material used for the object to be illuminated. The optical coefficients of different materials are different, and the coefficients of absorbing, transmitting, and reflecting light are also different. According to different materials, it is essential to select the necessary illuminance. 2) Outdoor creative billboards also need to determine the illuminance according to the characteristics of the advertising screen. If the image is delicate, the illuminance requirement is high. If the image is rough and concise, the illuminance requirement can be lower.
2. Appropriate illumination uniformity The lighting distribution should have a certain degree of uniformity. Uniformity of illuminance refers to within a given plane range: 1) The ratio of the minimum illuminance to the average illuminance; 2) The ratio of the minimum illuminance to the maximum illuminance. Minimum illuminance: the minimum illuminance value on a given plane; Maximum illuminance: the highest illuminance value on a given plane; Average illuminance: The average value of illuminance on a given plane. Usually, the illuminance uniformity adopts the ratio of the minimum illuminance to the average illuminance. Under normal lighting conditions, the illuminance uniformity should be ≥0.7. Of course, for outdoor creative billboard lighting, the more uniform the illumination, the better. If it is too uniform, there will be a lack of brightness variation, resulting in a dull picture. Appropriate illumination changes can form a more active wavy scene, and proper use can increase the picture effect.
3. Appropriate light color and color rendering of the light source 1. The light color of the light source The light color is the surface color of the light, and the light color of the light source is often evaluated quantitatively by the color temperature. It is the color temperature (light color) of the light source, the symbol of color temperature is T, and the unit is absolute temperature. The light color of the light source has a great influence on the rendering of the atmosphere. The light with high light color makes people feel light and dynamic; the light with low light color makes people feel warm and full of stability. The former can fully express the characteristics of objects with strong textures such as metal, porcelain, glass, etc.; the latter can better display the characteristics of soft objects such as wood, cloth, clothing, and carpets. 2. Color rendering of the light source The color rendering of a light source refers to the influence of light on the color of the illuminated object. The color rendering of the light source has the function of displaying the color of the object. From a physical concept, the color of an object changes with different lighting conditions. The degree of agreement between the color of an object under the light source to be tested and its color under the reference light source is defined as the color rendering of the light source to be tested. A reference light source is a light source that represents the true color of an object. Generally, noon daylight is used as the standard reference light source. The color rendering of the light source not only has the characteristics of displaying the color of the object, but also helps to create the atmosphere of the environment. To sum up, the lighting of outdoor advertising is very important for the proper uniformity of light. The above content is provided by WOSEN.
