Wall luminaire
METRO LED lighting system

High energy efficiency, modular design and optimized thermal management

With its optimized LED-Matrix, the METRO luminaire has a very precise and even spread of light with very little glare and low energy consumption. An important factor regarding durability is sophisticated heat management. The compact luminaire transfers the heat from the LED to the METRO housing, which acts as a heat sink. An innovative coating protects the housing from corrosion without insulating it. The CLO technology, by monitoring the luminous flux, insures a constant lumen output, further increasing the longevity. The METRO design is optimised for low life cycle costs: easy installation, a continuously adjustable lighting angle, custom glass with duplex anti-reflection coating and high transmittance, as well as clever modularity ensure a high user-friendliness.

Customized lighting

1 technology - 2 sizes - 6 installation adapters

BURRI public elements has over 80 years of experience in the manufacturing of lighting poles. 40 years ago, BURRI contributed significantly to efficiency and flexibility in street and areal lighting technology with its innovative light mast coupling. From the beginning of concept phase BURRI is focused on low life cycle costs, flexibility and high usability. Hence, besides state of the art LED technology, the modular METRO-LED lighting system offers easy installation and handling. Thanks to an optimized adjustment mechanism the spread of the lens guided light can be customized to suit the requirements on-site. This allows for a precise illumination with little glare or light pollution.

Innovation and Competence through Networking

Developed with industrial microsystems AG and NOSE

The contemporary design, where form follows function, was created by the renowned industrial designers of NOSE from Zurich. With its compact, yet elegant design, the METRO LED light integrates subtly into every modern cityscape. In close collaboration with industrial microsystems AG, a precise, modular luminaire was developed. The company has longstanding expertise in modern traffic management regarding LED technology and control systems. Furthermore, flexible manufacturing in Switzerland also allows for smaller batches with specialized equipment and an individually customized light spread and control unit.

High efficiency and longevity

Premium materials and optimized heat-management

The flat custom glass with duplex anti-reflection coating prevents glare and combines 99% transmittance with a high degree of self-cleaning. The compact aluminium luminaire is closely fitted into the aluminium housing, providing optimal heat-management. A specialized oxide coating, similar to those used in the defense industry, protects the surface and allows for a convective flow of heat without an isolator (such as lacquer or coating).

Energy efficient through smart controlling

Night time dimming, CLO (constant light output) and heat management guarantee longevity

An important factor regarding durability is sophisticated heat management. The compact luminaire transfers the heat from the LED to the METRO housing, which acts as a heat sink. Customizable, two level night time dimming grants significant energy savings, while allowing for adequate lighting at the same time. The CLO technology, by monitoring the luminous flux, insures a constant lumen output, further increasing the longevity. Careful optimization of the LED matrix has allowed for a significant increase in light spot distance. This allows for a wider luminaire spacing, markedly lowering the investment needed.
