Design steps
1. Determine the desired lighting art effect, which should be determined according to the properties of the building's true color.
2. Select the appropriate light, the choice of light color, color rendering, efficiency, life and other factors should be considered.
3. Decide the required illuminance. The required illumination depends mainly on the brightness of the surrounding environment and the color of the exterior wall of the building.
4. Select the appropriate luminaire, choose not only the light distribution characteristics, appearance, material, dustproof and waterproof grade, etc. must also be considered.
5. Calculation of illumination and number of lamps.
6. On-site commissioning after installation.
Illumination requirements for common outdoor locations
Venue name
Specified lighting area, average illuminance, square, ground, square area, 5-15, parking lot, ground, parking area, 5-10
Tunnel, inner area of ​​tunnel, 10 main roads, ground, driving area, 2-5, walking track, ground, pedestrian area
1-3, main roads in residential areas, ground and pedestrian areas, 1-3, residential area promenade, ground, pedestrian area, 0.5-1
Park road, ground, pedestrian area, 1-3
Several forms of outdoor lighting
Square lighting, pole lighting, courtyard lighting, low pole lighting
Square lighting mode (height 15M-30M)
Middle pole lighting (height 6M-8M)
Courtyard lighting (height 3M-6M)
Low pole lighting mode (height below 1M)
Located in a prominent position in the square.
The setting should create a sense of center and become a symbol of the regional center.
High cost, difficult to install and maintain.
Requires high security.
The light source is a high power high pressure sodium lamp or a metal halide lamp.
It focuses on the wide urban roads and the two sides of the roadway. It is mainly used for driving, and it is required to ensure the brightness of the road.
It is required that there should be no strong glare to interfere with the sight of the train.
The illumination is required to be more uniform, and the long distance is continuously arranged to depict the continuation of the spatial light.
Use high pressure sodium lamps.
Widely used in non-main lane streets, pedestrian streets, commercial streets, landscape roads, parks, plazas, schools, hospitals, residential quarters, etc.
It is required to ensure that the road surface is bright, and strive to make the combination of "light and shadow" rich in melody, because its height is low, and it can feel its existence. Therefore, it must be carefully designed according to the atmosphere of the environment, and has a good Security and preventive.
Mainly use high pressure sodium lamps, metal halide lamps or fluorescent lamps.
Not a continuous way of lighting, just highlighting the accent lighting in the trees or corners.
Pay attention to the outstanding effect of light generation.
Mainly use energy-saving lamps or incandescent lamps.
Outdoor lighting requirements
According to the National Standards of the People's Republic of China and the IEC (International Electrotechnical Commission) standards, road and street lighting fixtures meet the following basic requirements:
1. Structural requirements of the luminaire
2. About electrical distance and electrical clearance
3. Requirements for grounding regulations
4. Requirements for external and internal wiring
5, on the protection against electric shock
6, on the waterproof, dustproof requirements
7, on insulation resistance and electrical strength
8. Requirements for heat resistance, fire resistance and electric tracking resistance
9, on anti-corrosion, prevention requirements
Important public buildings, monuments, commercial buildings, square sculptures, or some unique landmarks, or transportation facilities in the city, can be beautified with lights at night, making the city's night scenes different. . Important public buildings, monuments, commercial buildings, square sculptures, or some unique landmarks, or transportation facilities, can be beautified with lights at night, giving the city's night scenes a different landscape.
