About ERCO

About ERCO

ERCO is a leading international specialist in architectural lighting, using 100% LED technology. The family business, based in Lüdenscheid, in the heart of Germany, now operates as a global player with independent sales organisations and partners in 55 countries worldwide. Founded in 1934, ERCO pioneered architectural lighting across Europe in the 1960s, and today, less than 50 years later, is the first established luminaire manufacturer with a portfolio based entirely on LED technology. Around 1,000 committed and dedicated ERCO employees worldwide ensure that LED technology is developed from a pure technology into a sophisticated lighting tool - because perception-orientated lighting design, implemented in the context of efficient visual comfort, is our mission. Focus at ERCO is given to open, interdisciplinary and international cooperation: While our ERCO luminaires are developed and produced carefully and with an eye on the future by our team at the Lüdenscheid Light Factory, our competent and motivated consultants at international ERCO sales offices ensure that they are used in thousands of different applications around the globe. We would be delighted to offer you the possibility of experiencing ERCO lighting tools in operation: in any of our ERCO showrooms worldwide as well as in workshops at our headquarters, and of course at trade fairs and other industry events.

ERCO acts responsibly in dealing with resources such as raw materials and energy - toward our customers, employees, and the environment. This is demonstrated in various fields of action: from our products and production to our corporate architecture.

Welcome to ERCO – in talks at the Light+Building booth.

The Light Factory in the digital age
When ERCO signalled that it was the first established luminaire manufacturer worldwide to develop, produce and sell light based entirely on digital technology, the news caused great excitement in the lighting and architecture sectors. “light digital” has since become our leitmotif, summarising our approach to reconsider lighting in every possible aspect based on the opportunities of LED technology. Development and production at ERCO are deliberately located in Germany, enabling us to guarantee ultimate precision and quality of our lighting tools – one more reason why we call ourselves the Light Factory. But is the metaphor of a factory not a touch outdated in the era of digital light? Not at all, actually. Whilst development work for ERCO LED innovations may, in some ways, be more representative of the agile, networked approach of digital start-ups, it is firmly grounded in the experience of an industrial company with a long tradition,

providing us with the means and momentum to concentrate on what ERCO has always done best: perfecting architectural light with ultimate precision. Every aspect of the process, from the design and development through to production and assembly, is handled under one roof. The short distances promote interdisciplinary dialogue whilst maintaining the superior quality for which we are recognised. Working with an international network of ERCO consultants, we keep our finger on the pulse of time and beyond, committed to the continuous development of products that meet the current requirements of architects, lighting and electrical designers in the field. One year after our complete and radical change to digital light, ERCO LED technology has now become a natural choice for creative and technical designers as a tool for more user-friendly and energy-efficient concepts of perception-orientated architectural lighting.


Efficient visual comfort
Lighting requires energy. Manufacturers, designers, engineers and users are obliged to use limited resources to the greatest effect. ERCO helps you rise to this challenge by supplying only the most efficient LED technology. Efficient visual comfort (EVC) for ERCO means a permanent and consistent optimisation of both the energy efficiency and the light quality through innovative technical concepts that enable sustainable lighting design. EVC, as a strategy, rests on the intent of designing light with focus on the user based on the principles of human perception, requirements of the space and efficient glare control, thereby minimising energy usage. We have defined five quality factors that describe efficient visual comfort at ERCO.

Qualitative lighting design
In putting people at the heart of its strategy, ERCO develops and designs its products with focus on a careful, perception-orientated approach to lighting design. ERCO lighting technology uses light to create hierarchies of perception, and specifically, to ensure optimised performance of the visual task at hand. Qualitative lighting design centres on vertical illuminance and accentuation, as well as glare control. Glare-free surroundings with consistent luminance levels are easier on the eye, eliminating the need to adapt constantly to changing lighting conditions. This enables the designer to produce an energy-efficient solution based on lower illuminance levels and subtle contrasts.

Vertical illuminance
Due to the natural orientation of our visual field, the vertical planes of an environment constitute around 80% of our perception, making them far more important to the subjective perception of brightness than the light on horizontal surfaces. Vertical illuminance, therefore, is a characteristic feature of well-designed and economical lighting concepts. ERCO offers an exceptionally wide range of appropriate lighting tools. Our wallwashers produce a wide and spacious impression of the room whilst reducing visual contrasts to provide excellent lighting for the workplace with minimal energy requirements. The use of LED technology pays off yet again here by producing light of utmost precision and uniformity and ensuring maximum efficiency in energy use and maintenance. The large luminaire spacing possible with ERCO’s wallwashers supports the cost-efficient context of vertical illuminance.

Effective lighting technology
Efficient, precise optical systems lower the energy requirement for lighting. A comprehensive array of solutions ensures optimised light distribution for specific lighting tasks. This extends from the asymmetrical wallwasher to various spotlight characteristics. ERCO lighting tools offer highly effective technology designed to direct the light specifically onto surfaces relevant to perception. The projected light of LEDs, combined with the high-quality lens systems provided by ERCO, ensures significant efficiency advantages over conventional light guidance through reflection.

Intelligent lighting control
ERCO offers luminaires for different control technologies, such as DALI control and phase dimming. This makes scenic lighting uncomplicated and accessible. Typical scenarios include the use of presence detectors to dim or switch off lighting in unused rooms. Similarly, ambient lighting sensors or analogue daylight sensors can be used to recall light scenes to supplement the available daylight. ERCO lighting tools combined with control gear developed in-house guarantee optimised dimming characteristics, making most of them ideal for filming, with continuous dimming down to 1%.

Efficient LED technology
ERCO’s accomplishments and leading role in architectural lighting with LED are based on the decision to draw on its own expertise in optoelectronics. With in-house development – from LED PCBs and electronics to thermal management – ERCO is always in control of its products and their specific characteristics. Therein lies the basis for the efficiency of our luminaires and the principle at the core of each and every ERCO lighting tool: specifying the highest standards for our high-power LEDs, based on criteria such as colour rendering and constancy, luminous flux and thermal stability, enables
us to guarantee consistently exceptional quality in terms of luminous efficacy and long life. By changing to LED technology, ERCO now focuses its approach on creating lighting tools with light source and photometric technology combined into a single integral element to support maximum planning efficiency.

Qualitative lighting design
ERCO lighting tools afford the creative scope required for the lighting design of complex building projects. With this in mind, our products are developed on the basis of a perception-orientated approach to lighting design. The American architect and lighting designer Richard Kelly (1910-1977) distinguished the qualities of light into three basic functions: ambient luminescence, focal glow and play of brilliants. This “language of light” is an optimal solution for the illumination of architecture – from the large open-plan office and boutique through to the library – as it contributes significantly to meeting the requirements of its users. Experience has shown that lighting concepts are considered to be pleasing and successful when all three components – ambient lighting, directed accent light and decorative lighting effects – are present in a well-balanced relationship. The “language of light” is a reliable approach used to analyse and structure lighting concepts and to select the right lighting tools. With a variety of light distribution patterns, warm white and neutral white light, different sizes and lumen categories, the system design for the luminaires in our extensive ERCO range offers all the components required for a differentiated and user-focused lighting concept.

Lighting design
Light is essential. Light is poetic. Light provides atmosphere and orientation. People have always used light as a way of creating harmonious places. ERCO understands light as the fourth dimension of architecture. As a design feature in its own right, light can model space and objects using different levels of illuminance and alter the nocturnal appearance of architecture significantly. The ERCO product range is based entirely on LED technology, as a logical consequence of our position in delivering perfect light. LED light, with its flexibility and precision, has widened the options of modelling architecture significantly and can now satisfy any and all requirements. Our lighting tools are developed in close collaboration with architects, lighting designers and electrical consultants. Intensive dialogue with the industry stakeholders gives ERCO a clear, realistic and yet also a visionary idea of what the designer requires. Creative thinking inspires us, and we want to share this inspiration. We see our role as consultants, working in the background to support designers in the implementation of their concepts with targeted solutions.

Product design
From the corporate architecture of our factory through to the clear style of our lighting tools and our meticulous corporate image – design has always been at the heart of ERCO’s process. Strong concepts and creativity form the backbone of a design team focused on the creation of a distinct design language for our LED product range on the principles of functional minimalism. At the same time, our team is permanently engaged with advancing our archetypal, modular system principles, whereby aesthetic aspects of spatial design are given the same attention as functional parameters such as efficient thermal management and glare control. Available in several sizes and with different mounting options, the luminaires in the ERCO range offer an appropriate solution for a wide variety of applications as well as spatial settings and dimensions.

Production and assembly
All processes at the Lüdenscheid facility, from electronics and tool manufacturing all the way to polymer production and metal-working, are closely monitored by ERCO experts and consistently optimised to guarantee efficiency and superior quality. Our electronics production is ESD-secure and the controlled reflow process is continuously monitored, for optimised assembly based on a meticulously researched time and temperature profile. The result is products that ensure long life and remarkably low failure rates. The same attention to detail carries through to the in-house production of ERCO track, providing designers and fitters with the best possible infrastructure to support the installation of lighting systems. Our suppliers are just as carefully selected for lasting partnerships built on trust. Working closely as a team, with short distances between development and production, ensures that ERCO customers can rely on our products 100%.
