Public light has a significant impact on the City budget, on the citizen safety and on the environment.

Leds achieve the expected 40 – 60% energy savings and reach up to 70% savings when coupled with “SMART CONTROLS”.

Today, LED lighting technology has come of age and is able to deliver benefits to cities and citizens alike. It offers more controllable and higher quality light, enhanced visual performance and improves the ambience and safety of urban environments. Moreover, LED lighting will make our cities ‘greener’ by saving up to 70% of lighting energy and reducing costs compared to existing lighting infrastructures.

Street lighting is an important part of a municipality’s nighttime. Landscape lighting can be used to enhance public safety and security while improving the aesthetic appeal of the surrounding properties. However, street lighting represents a large electrical load and can be one of the highest costs for a municipality.

Design and Engineering of public lighting systems.

All design and engineering needs from one source.

ELEF has developed a comprehensive approach to offer a full scope solution for design, including lighting, intelligent control systems, street furniture, security, signage and many other smart features.

ELEF can provides municipalities with a step-by-step process for improving the efficiency of street and public space lighting, and upgrading to LED technology along with the smart control.

The city’s requirements are translated into a workable design. The first step is an audit to determine the status of the system in place, which includes the cost of energy consumption, service and maintenance. The selection of the luminaire, light source and control system to be used is an important one, if electricity is not to be wasted and an efficient lighting installation achieved.

The most common application areas for LED outdoor lighting are:
Major roads

LED streetlights make major roads safer for both drivers and pedestrians.

Urban streets

In recent years, society has become more aware of the importance of making people feel safe, comfortable, and connected with their cities and communities. Intelligent lighting has proven to be a highly effective and cost-efficient way to re-humanize our urban environments – reducing crime, promoting tourism and encouraging a real sense of civic pride and identity.

Residential areas

Lighting is key to making residential areas safe, secure and attractive especially in those parts of cities that have been long overlooked. Highly efficient optics and dimming possibilities make LEDs the perfect choice for residential areas. Their precise beam control also minimizes light spillage. Light is distributed only where and when it is needed, preserving the night sky and ensuring that city residents enjoy a sound night’s sleep.

City centers

Cities are looking for solutions to their lighting requirements that go beyond just providing light points; they want inspirational ideas that contribute to the identity of the city and instill a real sense of pride. Intelligent lighting solutions enhance city centers, creating an attractive and inviting atmosphere that encourages socializing and enriches the city’s night life.

Supply and installation of public lighting systems.

Works properly done and on schedule are the keys of ELEF’s success on projects implementation.

In the case of a retrofit project, realization will be relatively simple and limited to scheduling the project to reduce impact on the surrounding area.

For larger projects, installation and integration will be more complex. Project management is essential to realize the project on time, within budget, and in conformity with quality requirements.

Preferential partnership with leading LED manufacturer provides ELEF access to the latest technology and quality products.

Management, monitoring and control systems.

Connectivity will lead to more innovations, the time is right for connected Public Lighting within Smart Cities.

Street and outdoor lighting is no longer purely an on/off system: increasingly, cities are moving toward outdoor lighting systems that are more dynamic, intelligent and flexible.

In the age of “Smart Cities”, outdoor lighting becomes a dynamic platform enabling continuous innovation, and therefore needs to be looked at from a different point of view. Outdoor lighting and “Smart City” development Investment in smart lighting networks also lays the foundation for long-term cost reduction by serving as a backbone and launching pad for “smart city” development.

The next step in the evolution of outdoor lighting is the smart lighting network. Powerline or wireless communication solutions can then be used to control entire sections of luminaires, aided by software that provides continuous monitoring, metering and a range of intelligent management options.

Furthermore, the ability to remotely monitor and adjust LED output through smart controls opens up three significant sources of financial savings:

• Maximizing energy savings by dimming lights to match the required standard, reducing output at sunset and sunrise, and dimming during periods of lower pedestrian/traffic activity

• Maximizing LED lifespan by dimming, and by adjusting light output upward as the product depreciates over time

• Minimizing maintenance costs by remote detection of faults and failures, and by GPS mapping of luminaires.

Such solutions could have following features: 

• Central control

• Complete monitoring

• Dimming

• Remote metering

• Power quality metering

• Voltage stabilization

• Control room installation

Systems integration advantages.
The remotely managed system allows cities to add on video-surveillance systems, wireless communications, variable message information monitors, and various kinds of sensors.
Energy saving 40-60% from retrofit

Efficency. Robust energy savings of 40% to 60% compared with conventional technologies are now common, and can yield significant reductions in a city’s operational costs. Furthermore, the operational optimization could lead to an additional 10-15% energy savings.

60% reduction in maintenace from retrofit

Superior control over light color, intensity and direction allows novel lighting designs that can deliver a wide range of social benefits. These include greater productivity in the central management of lighting assets, and new applications.

LIFESPAN. Well designed LEDs are expected to last for 50,000 to 100,000 hours or more, especially in cold climate in which LEDs thrive. Lifespan can be extended even further by coupling LEDs with adaptive controls.

Reduction of greenhouse gas emissions and light pollution

Environment. LEDs contain no mercury and can be easily recycled  semiconductors are typically made of sand. Energy savings from LEDs can also cut carbon emissions. Finally, due to the directional character of LED light, dark sky pollution can be eliminated

Smart City ready

Smart City system has been designed to be integrated in light output management systems. Each fitting features a dimmable electronic driver that can interface with a module designed to control the drivers’ power supply and, consequently, the intensity of the luminaire’s light output. This system also allows the street light to be incorporated into a local communication network, making it part of a smart system for the provision of integrated public utility and security services.
