The things that are designed for the lighting of the city square

The traffic plaza formed by the intersection of the urban road and the three-dimensional intersection should have high requirements for the illumination illumination and illumination uniformity due to the large traffic flow.

The lighting of the traffic plaza should be based on functional lighting. The illuminance should be greater than the lighting level of the expressway. According to the illuminance of the well-designed traffic plaza, it is generally around 100Lc. In order to limit the generation of glare, the height of the pole should be increased. It is better to use a centrally arranged disc or a high pole light in the ball, or a projection type medium and high pole light can be used.

In short, to ensure that the driver's visual work within the scope of attention, the angle between the illuminator and the driver's eye horizontal line of sight is greater than 45 °.

Municipal Plaza, Memorial Square

Generally speaking, part of the Municipal Plaza and Memorial Square or a certain direction has the nature of a transportation plaza. This part of the traffic plaza can be illuminated by pole lighting. It cannot be used for lighting such as garden lights. It is strictly forbidden. Use non-cutting luminaires.

The greening and sculpture of the square can be decorated with colored metal halide lamps; the monuments, memorial towers and monumental sculptures on the square are suitable for decorative lighting with daylight-colored metal halide lamps and high-pressure sodium lamps to show their solemn feeling. .

The lighting of the Municipal Plaza and the Memorial Square should be layered. Except for the landmark buildings, the illumination in other places can be controlled within 10Lc. Square lighting should make people feel comfortable and relaxed. We should pay attention to four lighting elements: three-dimensional sense, limited glare, visual effects of lamp-type lamps, color temperature and color rendering.

Entertainment and leisure square, commercial square

In recent years, many cities have built green squares (or civic squares) for the entertainment and leisure of the citizens. The lighting of the green square should suit the physiological requirements, safety requirements and communication requirements of the visitors. Therefore, the lighting of the leisure square should meet the following specific requirements:

1. Make people feel relaxed, comfortable, casual, and be able to calm down and avoid uncomfortable glare.

2. Meet the requirements of detecting obstacles.

3, to meet the brightness of the visual orientation, the illuminance of the square logo, the sign can be slightly improved, to help people who are not familiar with the surrounding environment to determine the direction.

4. From the perspective of safety and communication, it is necessary to ensure that the face of others or the characteristics of others can be recognized within a range of about 10 meters.

Entertainment and leisure squares should focus on landscape lighting, pay attention to the visual effects of lamps and lamps, and pay attention to the reliability of light poles and grounding of poles and lamps. In addition to the main entrance and exit to install 1-2 盏 functional lighting, the illumination of other parts is controlled within 5Lc.

Light sources such as aerial glare searchlights should be installed on tall buildings near the square. The recommended height should be more than 20 meters. The commercial plaza is for commercial purposes. The brightness of the store and other merchandise display areas is high, and the appearance, color, etc. of the goods can be clearly distinguished. Therefore, it is required to use a light source with good color rendering. In other places, under the premise of minimizing glare, various color light sources are installed to create a colorful and colorful scene to render the atmosphere and attract consumers.
