Lighting case: night lighting design of campus buildings

Architectural night lighting is the transition from a twilight environment to a luminous environment. In the design of architecture and environment, the influence of various light elements on the nighttime atmosphere should be considered, so that the observer can obtain good light color illumination and psychological feeling at any position relative to the environment, and with the observer's point of view Movement creates an ever-changing impression of space.

First, the nightscape lighting design features of campus buildings

China's colleges and universities are mostly relatively independent and special community environments, which have the characteristics of urban communities and urban residential areas, and elements different from ordinary urban environments. The night illumination of the campus should be simple and elegant, and the light color should be light and elegant, but not as beautiful as the commercial district or leisure and entertainment venues, emphasizing the rendering of its bustling and rich atmosphere. Applying the organic combination of lighting art and science and technology, interpreting the cultural connotation of campus environment, highlighting the artistic characteristics of campus architecture, and representing the openness of university campus has become the universal pursuit of contemporary campus architecture night lighting. Therefore, its design is a relatively independent subject, subject to education, aesthetics, philosophy, psychology, economics, architecture and many other aspects, requiring lighting designers and architects to work together from design thinking, design concepts and design techniques. Thoroughly understand its unique creative laws.

1. Focus on the environment, pay attention to the context

Under the guidance of the policy of “rejuvenating the country through education and rejuvenating the country through science and technology”, the construction of colleges and universities in China has developed rapidly. The campus environment highlights the campus atmosphere and regulates the campus architecture. Therefore, the campus night lighting must be attached to the campus environment. The meaning of "environment" here includes the elements of society, culture, time, history, and psychology. The campus environment is the most direct, most specific and influential element in the design of night lighting for campus buildings. The understanding and grasp of it is the key to the success or failure of night lighting design in a specific creative space.

2. Night lighting utilization resources

Campus buildings, especially complex buildings, are mostly divided into large open spaces. In order to create good lighting and ventilation conditions, the window opening area is large. The indoor space utilization rate is high, the use time is long, the indoor lighting requirements are efficient and clear, and the illumination is sufficient. Therefore, it is not necessary to install special internal light-transmitting lighting equipment, as much as possible to use the lighting required for indoor functions as the illumination source of the building night scene, let the indoor light shine outward, and use a large number of windows to form a bright luminous surface to decorate the architectural night scene. Make it unique and lively. In this way, indoor lighting resources can be fully utilized, saving lighting investment and operating costs, and facilitating maintenance and repair of lighting equipment. “Inside Light” has become the most unique and fascinating place in the night view of campus buildings.

3. Highlight key points and strengthen display

Campus night lighting can be flexibly diversified, emphasizing the characteristics and important areas of the building, deliberately creating the night atmosphere of the campus. By fully dissecting the functions, features and styles of the objects being illuminated, the paper understands the specific effects of light and shadow and the environment, simulates the night scenes of each viewpoint and line of sight, and enhances the visual perception of architecture and environment. Enrich the building's size with night scene lighting that exaggerates or exaggerates the building's bumps.

The exterior wall materials of campus buildings are generally soft and stable in color, and the use of light colors should be harmonious and bright. To express the characteristics and texture of building materials, it is necessary to master the direction and angle of use of light. The beam of illumination is generally not suitable for vertical illumination of the illuminated surface. If the illuminated surface is a large block, the incident angle is generally controlled between 55° and 85°. If the illuminated surface has a large increase or decrease, the incident angle is 0° to 60°. In order to form a moderate contrast between light and dark and good shadows. The lighting engineer must make an on-site adjustment of the luminaire angle to achieve the best lighting results.

4. Respect nature and add environmental anger

The design of the night illumination of the campus garden is an integral part of the design of the campus building environment. Through the changes in the brightness and color of the lights, the garden lighting shows the gentleness and broadness of the green grass in the night, revealing the bright and splendid flowers of the magnificent flowers, editing the trees and the shadows of the trees, and easily connecting the buildings and campus, campus and nature, nature and people.
