WE-EF LEUCHTEN Post Top Luminaire

CFT5402015

Design and Engineering

The most important element in the design process is the development of luminaires that

encompass timeless design; in other words, design that best reflects their enduring

qualities.

In addition, state-of-the-art engineering brings with it the highest standards with regard

to environmentally-friendly materials and processes, i.e., high IP ratings, excellent

thermal management and innovative optical systems. The development of high-end,

efficient reflectors and lenses is one of the core competencies of WE-EF. This means

compliance with international lighting and safety norms, while meeting the criteria of

such organisations as the Dark Sky Society. Continual investment in research and devel-

opment is the basic condition for meeting these requirements. WE-EF innovations, such

as IOS® Innovative Optical Systems, CTA® Cool Touch Adaptor, ASC Anti Slip Coating and

OLC® One LED Concept, are just some examples of the company’s continuing investment

in technology.

Production

'Made by WE-EF' is more than just an expression; the high quality level of in-house

production processes includes:

Tooling for HPDC and injection moulding

Aluminium high-pressure die-casting

CNC machining

Powder Coating

Pole manufacturing

Assembly

Through continual investment in tooling, production processes and the ongoing

education of our employees, we are able to achieve the highest standards of quality.

In exterior lighting, the corrosion resistance qualities of a product are important for their

reliability and longevity. A durable and reliable corrosion protection can only be achieved

when Product Development and the Production Processes are considered together.

Years of research, development and practical testing and experience in some of the

harshest climates on earth has resulted in WE-EF’s unique 5CE corrosion protection sys-

tem. It encompasses five critical elements; Material, Conversion Coating, Powder Coat-

ing, PCS Polymer Coated Stainless Hardware and Process Control. Only complete

systems such as 5CE can provide reliability and longevity in exterior environments.

Application

Real and sustainable cost and energy savings can only be achieved through professional

project planning, including the application of the latest optical systems and light

sources. In streetlighting applications, for example, this means minimising the number

of luminaires required by optimising the efficiency of the optical system, while at the

same time limiting glare in line with international standards. In short, reduced installa-

tion and maintenance costs, less CO2 and improved quality of light.

Recycling

More than 90 per cent of a WE-EF luminaire can be recycled. The main component,

a marine-grade aluminium substrate, is refined from recycled aluminium. This recycled

aluminium is also an 'energy storer'. Only 5 per cent of the original energy needed to

process bauxite into aluminium is required for recycling. In other words, 95 per cent

of the original energy input is also recycled.

Using either a 1-10V or DALI interface withelectronic converter, the light output and energyusage of the individual luminaires can be controlled. All components of the luminaire areengineered for reliability and longevity.

RFC® technology – engineered with a UV-sta-bilised PMMA panel which has a contoured sur-face, contoured in a way that imitates the shapeof the LED lens; the goal is to minimise the lossof light that normally occurs due to internal re-flection.

The OLC® technology is the ideal method forachieving a uniform and energy saving lightingsolution, providing highest safety and visualcomfort, in ensuring that the failure of individualLEDs does not lead to an adverse affect in thelighting.

With the intelligent use of a built-in vent, pres-sure fluctuations are equalized reliably and lessstrain is put on the seals, ensuring the sensitiveinterior electronics are protected against mois-ture penetration for years to come.

The CFT540 is fitted with a 6/6 kV surge protection, which is integrated in the LED driver, in accordance with IEC 61643-11. If the surge protector has been triggered by an adverse event, the luminaire is auto-matically disconnected from the mains.

In risk areas we recommend the addition of a 10/10 kVoptional WE-EF surge protection SP10 for the luminaire.

Important:For comprehensive protection of the luminaire against lightning and electrical surges, we generally recom-mend primary (Type 1) and secondary (Type 2) surge arrestors be installed into the switch board.

Outstanding and long lasting anticorrosion propertiescan only be achieved by a comprehensive, integratedapproach. WE-EF's unique 5CE system encompasses5 Critical Elements: Material, Conversion Coating, Powder Coating, PCS Hardware and Process Control.

PCS coated fasteners made from austinetic stainlesssteel reduce the risk of galvanic corrosion.

New shape for additional design possibilities: Thering-shaped luminaire body of the new CFT540 sub-sequently led to the development of new LED boards.
