A good lighting design uses light to enhance the character of a space creating not only a special ambience but also comfort and security. The right light promotes creativity, efficiency and productivity of people who are learning and working in the space and reduces errors. Innovative, unique and unmistakable atmospheres make a great impression on customers and for people with limited vision, adapted lighting makes everyday life easier.
Many of our designers work part-time – for us that’s sustainable and future-oriented, too.
The regional relationship to nature influences our work every day and motivates us to plan our lighting in a sustainable manner and conserve resources.
The whole spectrum. For spectrum, this means the professional, holistic and conscientious processing of our projects in all phases, from the first concept sketch to visualizations, lighting calculations, tendering, detailed drawings to construction management, lighting and commissioning.
Our range of work includes hand-drawn sketches as well as CAD-based drawings, computer-based light calculations as well as custom samples. Our way of working is based on many years of experience, professionalism, our internal network and our team spirit.

2020 | Our light brand spectrum is born in order to be able to position ourselves even better, to work even more efficiently and design-oriented and to be able to offer our customers the best possible project solutions. We form a close network with our sister companies. Together we operate across borders and have a pool of almost 40 employees. We see ourselves as a competent contact for the areas of lighting planning, sustainability, building physics and energy concepts within an interdisciplinary planning team. The understanding of the building as an overall system is reflected in our team composition with employees from a wide variety of disciplines. This diversity enables us to find proven and new approaches within the team to develop, assess and implement interdisciplinary. We develop and implement innovative projects with the highest design standards for sustainable, energy-efficient and environmentally friendly buildings. |
2017 | LDE Light Design Engineering AG Liechtenstein is integrated into Lenum AG / EK Energiekonzepte AG. This way, another area of holistic energy planning can be covered. Uwe Belzner was a co-founder of LDE Belzner Holmes in Stuttgart in 1989, and in 2003 he founded LDE Liechtenstein AG. |
2010 | Lenum AG takes over 3Plan AG’s shares in EK Energiekonzepte AG Since then, EK Energiekonzepte AG and Lenum AG have been sister companies that work closely together. Together we can access a wide range of know-how and a variety of well-trained employees. Lenum AG and EK Energiekonzepte AG develop and implement innovative strategies for sustainability in the field of energy and the environment. The building understands how it works in interaction with its surroundings. Only a precise coordination of all sub-areas (building physics & indoor climate, building technology & energy systems, material & building construction, economy & life cycle costs leads us to successful concepts. |
