Night lighting on some basic knowledge of skills

Local Landscape Lighting design is based on the characteristics of the illuminated object, from the lighting color and brightness, lighting layout, lighting and reasonable way to use one of three areas to achieve the best environmental art night lighting effects.
     Landscape Lighting Design of color and brightness
     Monochromatic light with night lighting and multi-color light of the points to smart low saturation is appropriate. High-saturation color of light, such as pink easily lead to "jump" feeling, rarely used. In color matching, the Landscape Lighting by color in a friendly, warm, dignified, distance, weight and other visual, the role of psychological feelings, showing a variety of different needs night ambience. Government agencies such as office buildings, radio stations, television stations, monuments and commemorative square, which places the main light colors should be pale. Like the yellow light, yellow-white light, red light or other shade can be local or highlight key positions, but never mess colorful, dilute the solemn atmosphere. Service buildings, such as hotels, restaurants, waiting lounge or entrance hall of the podium positions, should use warm colors such as orange light, contrast the environment is warm, friendly atmosphere. Downtown business district and cultural entertainment places, lighting or color should be present diversity of degeneration. Can be used neon signs, window lights, advertising light boxes, street lamps, to use the strobe light changes colors and rich presentation, a thriving scene, people to fully experience the modern city atmosphere. High-rise building, the bottom of the color with thick, dark colors can increase their sense of stability and solid feel, and * Department of color with a pale, light color can look more tall buildings, tall and straight, thus emphasizing the demonstration of the characteristics of high-rise buildings.
     Night lighting of the scene brightness of ambient light, landscape Juli, air quality factors, more complex, at present China is still not set relevant standards are often based on empirical estimation in practice. So this should be further study.
     Landscape Lighting lighting layout
     First, in light of the primary and secondary and focused direction to be followed, taking into account the general principle. Usually the main focus of the scene illuminated by the light parts, such as the importance of three-dimensional signs, pictures, nameplates, auxiliary optical parts used in general or background, so that the whole night rich layering. Secondary illumination light and the proportion of the general desirability of the main 3 to 1. Second, should be face to face shape and texture, select the appropriate form and direction of light cast. High-rise buildings, light can only be bottom-up projection lighting, so the direction of light cast shadows should be moderate and the performance of three-dimensional layering better. If the elevation is rough, good spread of light, then cast light incident angle can be larger and uses a narrow beam of light; If the surface is smooth, light is cast as far as possible the direction perpendicular to the surface and uses diffuse light. Glass curtain wall on the situation, to avoid "black hole" effect, should be used as the transmission format. In addition, lighting should also pay attention to their beautiful shape.
     Night lighting the way
     Modern lighting technology, providing lighting for the night, various means and methods. Currently, night lighting commonly used methods are: the Pan-sided lighting, contour lighting, as the transmission illumination, fiber optic tube, a small string lighting, laser holographic three-dimensional lighting and so on. Lighting can be achieved through the induction of these visitors the best view, highlight the landscape features, spectacular results.
     It is worth mentioning is that many of the places due to improper use of night lighting, causing light pollution, and even affect astronomical observations. Greenwich Observatory, the famous British had been forced to shut down. Observatory in many countries have moved to an island in the sea or mountains. My reconstruction of the Hong Kong Observatory site also had to choose the more remote Xishuangbanna. In addition, the day of the night lighting has also disrupted nocturnal plants and animals live a normal life, destruction of part of the ecological environment. These problems have attracted people's attention, will in the future development of night lighting should be carefully studied and resolved.
