Street lights are road lighting devices that reflect the characteristics of roads in urban environments. They are arranged in city squares, streets, highways, residential areas and garden paths for the night.
Transportation provides lighting convenience. Street lights have the largest number, the widest setting area, and occupy a considerable height in the street lighting.
The leading factor is the content that should be paid special attention to in landscape design.
First, the classification of street lights:
Low position street light
The space environment in which this kind of lamp is located expresses a kind and warm atmosphere, lighting the path for people to walk with a small distance. Buried in garden ground and embedded in buildings
Lighting fixtures for entry steps and wall skirts fall into this category.
②Pedestrian street lights
The height of the light pole is between 1-4m, and the lamps and lanterns include downlights, horizontally unfolded surface lamps, spherical lamps and directional controllable cover lamps. This kind of street light is generally set on one side of the road,
It can be arranged at equal distances or arranged freely. The shapes of lamps and street light poles highlight individuality, and pay attention to details to match people's perception at medium and close distances.
⑤ Parking lot and main road lights
The height of the light pole is 4-12m, usually a stronger light source and a longer distance (10-50m) are used.
④Special lamps and high pole lamps
Special lights refer to lighting devices set in factories, warehouses, playgrounds, gas stations and other areas with a certain scale and a height of 6-10m. Its light range is uneven
It is limited to traffic roads, and also includes related facilities in the venue and venues for evening activities.
High pole lights also belong to regional lighting devices. Its height is between 20-40m, and its illumination range is much larger than that of special lights. It is generally set in the square in front of the station and in large parking lots.
Fields, open-air stadiums, large exhibition venues, overpasses and other places. In the urban environment, the high column lamp has a strong pivot point and landmark function, and people sometimes call it a lighthouse.
is appropriate.
Second, the structure of the street lamp:
Street lights are mainly composed of five parts: light source, lamps, lamp posts, bases and foundations.
The light source converts electrical energy into light energy. Commonly used light sources today are energy-saving lamps, high-pressure sodium street lamps, metal halide lamps and LED street lamps. The basic conditions for choosing a light source are
height and chromaticity.
②The lamps distribute the light emitted by the light source according to the needs, such as point lighting, local lighting and uniform lighting. The basic requirements for lamp design are reasonable light distribution and efficiency
⑤The light pole is the support of the lamp. The height of the lamp pole and the light distribution angle (beam angle) of the lamp determine the irradiation range. In some occasions, the exterior walls and doorposts of buildings can also
To support the role of lamps. The height and distance of the lamp post can be determined according to the light distribution requirements of the environmental place.
④The base and foundation play the role of fixing the lamp post, and lead the cables laid underground into the lamp post. Some street light bases also have access openings.
Due to the different environments of street lamps, different comprehensive requirements should also be put forward for lighting methods, as well as the shape and layout of lamps, light poles and bases. street lights in the environment
It also reflects people's psychological and physiological needs, and is fully reflected in its different classifications.
