Illuminance standard: The illumination level of landscape lighting mainly depends on the material and color of the object surface, the degree of cleanliness, and the brightness of the surrounding environment. According to the characteristics of the surface decoration materials of the object, and referring to the relevant standards of the International Commission on Lighting, the design illuminance standard value of the bridge landscape lighting is determined, so that the brightness and color of the illuminated object and the surrounding environment are not only different, but also harmonious and coordinated with each other.
Control of glare: Glare not only refers to directly irradiated glare, but also refers to the phenomenon of discomfort or reduced vision caused by objects with extremely high brightness or strong brightness contrast in the field of view. Glare is an important indicator for evaluating lighting quality. Improper design and handling of lamps or excessive projection power will cause glare. The glare caused by the excessive overflow of floodlighting on the bridge landscape seriously affects the driving of passing drivers and the passage of pedestrians. Therefore, the control of glare is also a very important aspect in the landscape lighting design of bridges, and the position, angle and brightness of the light source must be strictly designed.
Lighting source: The bridge landscape lighting source should have high luminous efficiency, long service life and low power consumption. Reasonable light sources should be selected according to different use environments and requirements. When designing bridge landscape lighting, special attention should be paid to the selection of the anti-vibration performance of lamps and electrical appliances. Because most of the bridge landscape lighting fixtures are attached to the main body of the bridge, the bridge itself will vibrate due to driving, which will have a great impact on the life of the light source and electrical appliances, and a light source with good anti-vibration performance should be selected. According to the texture of the bridge surface material, the color light is used reasonably to express the characteristics of the illuminated, creating a unique atmosphere for the bridge landscape lighting and improving the overall lighting effect.
Lighting lamps: lamps are used to fix and protect the light source and adjust the projection direction of the light source to obtain a reasonable light distribution in the lighting environment. When designing, the light distribution should be selected according to the area of the illuminated surface, the distance between the lamp and the illuminated surface, and the design illuminance. , High-quality lamps with beautiful appearance. The installation of lamps mainly depends on the optical characteristics of the selected lamps, the relative position of the observation point, the distance from the illuminated surface to the lamps, the characteristics of the illuminated surface, the lighting conditions of the environment, and the expected lighting effects. When laying lights on bridges, avoid people's sight as much as possible, and install lights in hidden locations to avoid seeing lights without seeing lights. When the lamp must be exposed, the fixing bracket or lamp post of the lamp should be carefully studied and designed. The shape, height and color of the bracket or column should be in harmony with the object to be illuminated.
