Architectural night lighting: the use of floodlighting techniques and case studies

Wuzhen Scenic Spot Floodlighting Project

As shown in the following figure: shows the body shape of different illuminated objects, the lighting effects produced by the different viewing orientations (A) and the number, position and projection angle of different floodlights (B). In general, the effect of enhancing the stereoscopic effect can be obtained by projecting the divided group of floodlights in the same direction to the illuminated object, or projecting from the two directions in contrasting tones. At night, the visibility of architectural and sculptural details depends primarily on the brightness, so floodlights can be placed remotely or closely, as needed, or they can be exposed or hidden. Long-range projection can improve the uniformity of brightness; close-range projection can emphasize the details and texture of the illuminated surface. For the entire illuminated surface, when the average brightness of the upper portion is 2 to 4 times lower than that of the lower surface, the observer can be made to have a feeling that the upper and lower brightnesses are equal.

How to prevent glare in floodlighting

The main factors causing glare are: the brightness of the light source; the position of the light source; the contrast with the surrounding lighting environment; the size and quantity of the light source, etc. How to control the uncomfortable glare in the floodlight design? In some cities along the street store It is often seen that signboards and advertising signs use floodlighting, but the contrast between the brightness of the selected lamps and the surrounding environment is too large, the angle installation is unreasonable, and the surface of many signs is mirror-finished, which causes uncomfortable glare. Therefore, in the lighting design of signboards and advertising signs, it is necessary to consider the surrounding lighting environment. The illumination of the signboard is generally 100-500lx. In order to ensure better uniformity, the interval between the lamps on the signboard and the billboard should be installed. The length of the rack is 2.5 to 3 times. If the interval is too wide, a fan-shaped bright area will be produced. If side lighting is used, consider the occlusion of the luminaire so that the unwanted light is reduced as much as possible. In floodlighting of buildings, it is basically that the lamps are illuminated from the bottom up, which is less likely to cause glare.

Installation location of floodlighting fixtures on buildings

Shanghai Sanshan Guild Hall: The spotlights are evenly distributed along the old and new pavilions. The floodlighting at night makes the old pavilion's century-old vicissitudes and the new pavilion crystal clear, and it shines in the night sky.

In the decorative lighting of a building, the building art is fully embodied with as much light as possible, with little or no uncomfortable glare. In the design of floodlighting of buildings, the light source and luminaire should be selected according to the material, smoothness and shape of the building surface. The position of the luminaire is installed as close as possible to the back of the store or the decoration, so that the luminaire avoids people's sight, but the overall lighting effect must be considered and the shadow cannot be caused. In the case where the line of sight cannot be avoided, the luminaire should not be destroyed as much as possible.

The floodlighting of the building matches the surrounding environment

If the same type of lighting is used for tall buildings on both sides of the city's main roads, it will give people a feeling of dullness and even dullness. So how to solve this phenomenon?

First, it is necessary to consider that the materials of the building are combined with the light source of the luminaire. The illuminance of the floodlight of the building is generally between 15 and 450 lx, and the size depends on the surrounding lighting conditions and the reflective ability of the building materials;

Second, consider the combination of the shape of the building and the color of the light source. Color lighting can be selected according to the shape of the building, creating a distinct color contrast between the front and side of the building, adding a festive atmosphere;

Third, the building's floodlighting combined with neon lighting. For the building list, floodlighting is not enough. It can also be used with neon lighting. In the lighting design of a building, some of the buildings can be decorated with neon lights. The main building can be floodlighted. Neon lights form a subjective lighting effect. Special buildings can be combined with special lighting effects to complement the building and the environment.

Huizhou Zhongzhou Central Building Garden Club is a European-style classical style building. The main elements of the official roof, Roman columns and guardrails, porches, fountains, etc. are the main building elements, highlighting the noble and elegant, elegant atmosphere. Therefore, the design of the lighting must reflect the temperament of the building.

In the architectural lighting design section, the designer combines the overall lighting design concept to highlight the lighthouse at the top of the building complex. The lighting of the lighthouse is combined with the inner and outer light, and the contrast between the inner and outer lights and the color temperature are properly grasped. The light of the roof tiles and the lighthouse connection is weakened, and the rhythm lighting is expected to reflect the leisure atmosphere of the hotel.

The use of static projection and flashing light to create the royal temperament of European classical architecture reveals elegant, brilliant and atmospheric visual effects. The combination of full and rich lighting art and architectural style follows the principle of people-oriented, energy saving and environmental protection. The project highlights the uniqueness and artistry of the project.

In the landscape lighting design section, the designer pays full attention to the lighting manifestation of the water body, and uses the 100-300W fountain pool light to create a crystal clear water cube in the water body camp, conveying the calm and quiet mood of the water at night. In the clubhouse roof lights process, the designer is desirable with LED floodlight dimly light reflected steel roof, and can achieve a particular color-changing effects holidays. A large number of LED point sources combine to form a surface light, requiring precise lighting fixtures and intelligent lighting control systems.
