Architectural landscape lighting design concept

The important public buildings, monuments, in urban commercial building, square, sculpture, or some special modelling landmarks ( 土地马克) , traffic facilities such as Bridges or the MRT station, etc. , can be used at night lights to beautify, making the night scenery of the city in addition to the signature of neon lights can have different weather. Building flood lighting design in the overall consideration in any of the following is the first time confirmed. The direction of the watch: buildings may be from a different direction. Angles can be seen, but generally in the design before you start, we first have to decide a particular direction as the direction of main view. Distance: the average person may be viewing distance. Distance will affect the people for the sharpness of the facade appearance observation, affect both high and low intensity of illumination. Surrounding environment and background: peripheral environment and background of light and shade can affect the required illuminance. If very dark around you need some light is enough to illuminate the main body, if the surrounding is very bright lights must strengthen to highlight the main body. In addition to the structure of the surrounding environment, the exterior wall of the building materials is a factor affect the lighting effects the moment. Basically speaking, the rough surface of concrete, stone, tile and other materials after lamplight illuminate the effect is good, smooth surface of materials such as aluminum, stainless steel, glass total reflection caused by will, not only the effect of light do not show and the pollution caused by reflection, this phenomenon is most serious, especially in the reflection glass carelessly. Decided to different lighting effects buildings because of its appearance and may produce different lighting effects, are uniformly or feeling, or tone change strong feeling; Can be a plain expression, or more lively expression, all attributes to decide in accordance with the building itself. Choose to suit the choice should consider of the light source of light color, in color, efficiency, life and other factors. Light color have equivalent relations and building outside wall material, generally speaking, the brick, tan stone material suitable for use warm color light to illuminate, use light source for high pressure sodium lamp and halogen lamps. White or light color marble can use higher cold white color temperature ( After metal lamp) To illuminate, but using a high pressure sodium lamp or not. Decision required for the illumination of the required illuminance mainly depending on the light and shade of the surrounding environment and building external wall material color depth. Table 1 the illuminance value is proposed in view of the main facade ( The main viewing direction) Is concerned. In general, the minor elevation of intensity of illumination is given priority to half of the facade, borrow two sides of different shades of construction can show the stereo feeling. Decided to illuminate the subject of the way in accordance with the characteristics of buildings, building the base of the current conditions, to determine the most appropriate way of lighting in order to achieve the lighting effect of hope. Select the appropriate lamps and lanterns is generally square project-light lamp light distribution of Angle is bigger, lamps and lanterns of circular Angle is smaller. Wide Angle type lamps and lanterns effect is uniform, but not appropriate for distance projection. Narrow Angle type lamps and lanterns is fit to be a long distance projection, but close range when using poor uniformity. The choice of lamps and lanterns in addition to the light distribution characteristics, shape, texture, dustproof and waterproof level ( IP level) And so on are also necessary to consider factors. Intensity of illumination and the number of lamps and lanterns of calculation after the above steps are completed in accordance with the light source, lamps and lanterns, installation position of the selected conditions of illumination calculation to determine the number of lamps and lanterns, in order to the effect after the installation is complete to close as far as possible. The scene after the installation is complete the on-site adjustments is absolutely necessary. Computer designed each lamp projection direction is just for reference, the computer (illuminance value is calculated by a reference One eye can see is the reflection of metope luminance, not illumination) 。 So the adjustment of the site after the installation is complete, in fact, the people's eyes can see shall prevail. The projection of the appearance of the building at night USES light performance, the income effect and the feeling of the day there will be equivalent to the difference. So we don't need income on lighting design and same effect during the day, it is important to show the characteristics of the building.
