Three aspects to pay attention to in urban night scene lighting

1, the pursuit of lighting brightness is prone to light pollution

The production of artificial light sources is to improve life functions, realize high-efficiency, bright cities, and bright family life. However, with the rapid development of lighting technology and design skills, especially after the development and use of LED lamps, the orientation of improving the quality of life has changed, and today's lighting has entered the era of high brightness.

2. Do not destroy the original artistic style of the photographed object

Night scene lighting fixtures should be hidden, especially for large public buildings, ancient buildings, antique buildings and European-style buildings, beautify the night scene of tile roofs or vaults, and prevent damage to the aesthetic beauty of classical buildings. Lighting should be beautified during the day, and "see the light but not the light" at night. However, at present, there are still quite a few famous buildings in the domestic landscape that are damaged by exposed light strips.

Including billboards and light boxes in commercial streets, residential buildings, public squares and other areas, in the absence of regulatory constraints, light boxes are installed at will, light strips are interlaced, and even light boxes are stacked on top of each other. The appearance of many buildings is blocked to varying degrees. , and obstruct the appearance of the building, but also affect the line of sight inside the building. Seriously carry out scientific research on lighting fixtures or non-standard lighting fixtures, using LED or other new lighting technologies, is the way to study and solve the original historical and artistic features of the care landscape.

3. Be careful to use lamps with high energy consumption and strong glare

With the widespread dissemination of low-carbon environmental protection concepts, the use of high-quality energy-saving light sources with long life and high luminous efficiency is the purpose of the design.

At present, most of the urban night scene lighting uses LED, metal halide lamp, high pressure sodium lamp, medium color rendering high pressure sodium lamp, etc. Compared with incandescent lamps, the outstanding features of these light sources are high luminous efficiency, long life, and the disadvantage is that there are many accessories. Sexual investment is large.

The relevant specifications for lighting illumination in my country are that the protection level of the housing of lamps installed outdoors should not be lower than IP54; the protection level of buried lamps and lanterns should not be lower than IP67. While selecting lamps and lanterns in strict accordance with relevant parameters, high-efficiency lamps should be selected under the conditions that glare restrictions and light distribution requirements are met.
