Different public lighting(classicledlight) design layouts For two-way traffic roads, there are four basic lighting layouts:

Single side

This type of illumination is primarily suitable for situations where the road width is less than or equal to the installation height of the lamp. In this case, the brightness of the road away from the street side is inevitably lower than the brightness of the road on the side where the street light is located.


It is preferred when the road width is 1 to 1.5 times the height of the street lamp installation. When choosing this street lighting design, special attention should be paid to uniformity; otherwise, it is easy to have spots in alternating light and dark areas.

3. Double sided (relative)

Use when the road width is wider and exceeds the installation height of the lamp by 1.5 times.


This type of lamp is used on the exterior walls of buildings with very narrow walls on either side. The luminaire is installed in the middle of the cable.

Bidirectional channel with divider

We can find this layout on the highway. The central catenary lamp means that the lamp post is located on the central isolation belt along the road. The spacing of the lamps is approximately 10 to 20 meters. To further improve the quality of the lighting, we can use an alternate design as we can also provide illumination for the other side of the road.

The advantages of the central contact network arrangement are:

Excellent visual guidance for road users

Good uniformity

Reduce glare

Investing in energy-efficient public lighting(classicledlight) systems can change municipalities.

On the one hand, switching to modern street lighting solutions based on light-emitting diode (LED) technology provides urban governments with the opportunity to reduce energy, operating and maintenance costs while reducing the overall carbon footprint.

At the same time, reliable and bright public lighting can bring a range of social and economic benefits: well-lit streets make people feel safe, reduce accidents, and promote economic and social activities after sunset.

Given these advantages, moving from an outdated system to modern technology is a win-win solution for many cities around the world, but high upfront costs can be a deterrent. Attracting private capital through public-private partnerships can help municipalities raise funds to implement smart street lighting systems that ensure efficiency and high technical standards in the long run.

The Public Resource Partnership of the Infrastructure Resource Centre is a website that provides sample legal material that can assist with the planning, design and legal structure of infrastructure projects and has recently launched a sub-national section. Part of this section focuses on energy-efficient streetlight projects. Based on best practice cases, the new resources provide a variety of standardization and sample contracts and tender documents, as well as legal and policy projects that are used globally to implement successful PPP arrangements to provide small and large public lighting.

The first edition of the International public lighting(classicledlight) conference (August 14-15, 2018) achieved great success.

Since public lighting is an important source of energy consumption for Latin American and Caribbean countries, and according to the International Energy Agency (50-54% growth by 2030), the future will be even more important, so solutions need to be found. This means that city leaders need to be evaluated from the perspective of cost and operational efficiency, with luminaires and communication network technologies best supporting their energy-efficient and smart city plans.

About activities

The 1st International Conference on Public Lighting and Smart Cities is dedicated to accelerating the smart city agenda, identifying business opportunities, building partnerships, optimizing public lighting potential, improving regulations and fostering better knowledge among government agencies and policy makers, lighting operations Business solution provider. In the first edition, more than 400 participants gathered with all major Colombian participants.

The public lighting(classicledlight) is one of the public services that municipalities must provide in the areas they manage to make towns or urban dwellers safer and more accessible.

Public lighting is mainly about street lights, in many forms, such as the most traditional - lampposts and wall lights - as well as cutting-edge low visual impact devices. Local authorities must meet two requirements: limiting energy consumption and reducing light pollution, thereby shaping the technological development of public lighting infrastructure.

The most innovative technology solutions involve the use of remotely managed LED units. This intelligent lighting technology means that devices can be managed in a more innovative and efficient way, enabling users to:

By adjusting the light output according to the traffic demand of the vehicle, the energy consumption is reduced by about 65%, and the cost is further saved by 20%.

Manage units more efficiently by extending service life and reducing labor requirements.

Improves light quality with greater color rendering by the new light source for superior color perception.
