Rudolph, Horst

ITZ/Trilux, R&D Director


Horst Rudolph studied physical technics at the Iserlohn University of Applied Science. His interest in light and lighting began with his master thesis about diffraction of laser beams on irregular structures. 1988 he started his career at the TRILUX-Group as optical engineer. He developed optical systems for technical luminaires as well as a 3D-computer program to simulate light distributions, based on accelerated ray-tracing principles. He was engaged in national and international standardization projects of photometry, human centric lighting and LED light engines for many years as well as in manifold research activities on German and European level. Actually he is responsible for the lighting technology of the TRILUX Group.

Lighting Quality for the Next Decade – Visions and Mission for the Lighting Industry

This presentation will point out the dilemma of the lighting industry today with its high innovation speed, that the customers hardly can follow and too much opportunities for the lighting industry, that decision making is harder than ever. The last decades of technical development across the lighting industries were mainly focused on energy efficiency and cost down of products and components.
Taking a look on the “S-curve” which explains the market diffusion of technical innovations, many things, happened to lighting products in the past can be explained very well. In these convenient years, the speed of innovation was determined by “analog lighting systems” and driven by the light source industry.

The first step of “LEDification” began around the year 2000, where first patents were filed and the solid state lighting industry could point out the efficiency potential against all traditional light sources. Until 2017 LED has reached any lighting application and is much more than just a replacement of analog light sources. Optical systems, complete luminaires and totally new lighting systems were developed achieve the best system performance. In parallel Photo biological and Chrono biological aspects were discovered. Many research project have shown that there is a huge impact of light on human beings. The questions are now: how to put all this together and how to bring it in the market? What is the benefit for the customers of today and who is the customer of tomorrow? What will be the most promising business modell and what kind of support from governmental institutions can be expected?

This presentation will show some ways out of the lighting industries dilemma: With a high lighting quality for individual needs in different applications, that can be achieved with intelligent LED-drivers, light management systems and connected lighting installations. This picture of the “way out” grew over the last months, while preparing workshops for the German Ministry of Education and Research BMBF and formulating a position paper for the German lighting industry. Additionally actual research projects together with medical and technical institutes (for human centric lighting) as well as cooperation with several Universities (for quality of LED luminaires, adaptive lighting and illumination beyond energy efficiency) helped to clarify a picture of the future.

The presentation will show, how to use smart technologies for real customer benefit within several “visions” for a higher quality of light, where circadian illumination, the ability to fulfill visual tasks and also emotional aspects are three facets of the “human centric lighting”.
