Have you ever wondered how street lights are made? The essence of street lights in ensuring that commuting at night is easy can never be diminished. Accidents significantly reduce in places where there is presence of street lights. Still, street illumination ensures that crime rate is reduced hence enhancing safety in a given place. Further there is some sort of elegance that comes with street lights especially when patterns are made while installing them.
Street lights are made with the consideration of a number of aspects. Firstly, the street lights should be made in such a way that there is visibility and clarity for the majority of the people. This will therefore require that high voltage lamps are used to enhance this. Secondly, the poles used for street lighting should be made of long lasting materials such as concrete, fiberglass and metal poles among others. Still, the cables and wires used in the connection of the street lights must always be underground. This is particularly important in ensuring that accidents are not caused on the streets. Further, the poles and the lines must always be located away from the road. The landscaping will significantly determine spacing between the poles.
The type of lamp used will depend on the area being lit. Certain lamps will be more appropriate in some areas than others. For example, the residential areas may need to have different illumination than in the central business district. Further, there are specific lamps that are best suited for the dusty environments making them best suitable for street lighting. Still, there is a significant concern in coming up with energy saving street lighting. Several companies have been able to come up with lamps that ensure that there is proper street illumination, yet saving as much energy as possible.
The light poles must be made in such a way that they can withstand strong winds in the streets. Further, the poles should not be conductive and, should carry a significant amount of weight. A street light design consultant will normally calculate the;
- Height of the poles
- The spacing between two poles
- Length of the arm
- Size of the overhang among others
The basic aspects that will guide a consultant in this area are:
- Luminance level
- Uniformity of the luminance
- How effective the visual guidance is and
- The lamp spectra
Also, certain software will generally guide an individual to come up with the most appropriate calculations on the same. Street illumination is also done using various international standards. The calculations of the height of the poles and the spacing between poles are never at liberty of the people installing them. Therefore, the use of internationally recognized software will go a long way in helping to meet this. When street illumination is done properly, there is a guarantee of excellence in the area and low costs of maintenance.
