Rich document Focus Tunable Lenses for LED Lighting by Optotune AG
Focus tunable lenses open up new possibilities in the design of LED based luminaires. With these shape changing lenses, the beam angle of a spotlight can be flexibly adjusted while keeping the efficiency on a constant, high level. Compact solutions combining a floodlight and a spotlight in one product can therefore be realized. This innovative technology reduces complexity and offers more flexibility in lighting design, especially for changing environments like museums, and shops. Joerg Wertli from Optotune AG demonstrates a very interesting technology for these applications.
Rich document D source code Development Process for a Metal-Halide Replacement LED Module by Neonlite International Ltd.
Seen for the first time at this year’s Light + Building, the TECOH® MHx, has provided specifiers and designers with a viable LED metal halide alternative. Talking about the issues surrounding such a development, Fred Bass, Managing Director of Neonlite International Ltd., the brand owner of MEGAMAN, shows how the module series has been developed and highlights its potential for metal halide replacement moving forward.
Rich document Aspects of Light Quality in Solid State Lighting by OSRAM Opto Semiconductors
For ages the quality of light has been one of the biggest topics for luminaire manufacturers. But since the introduction of LEDs in general lighting the definition of light quality has got a new dimension. Pros and cons of LED lighting quality are often very controversial. Alexander Wilm, Application Engineering Manager of OSRAM Opto Semiconductors, presents facts about LED lighting quality that provide a sound basis for discussions.

In an interview with LED professional, Ms. Beate Jungwirth, Director of Marketing & Communications and PR at Everlight and Dr. Christopher Keusch, Senior Sales Manager at Everlight, talk about the market and development trends in the area of LEDs. The experts also discuss Everlight’s focus at the LED professional Symposium +Expo 2012 which takes place in Bregenz, Austria from September 25th to 27th.
Rich document An LED Solution for Historic Monumental Electric Chandeliers by Ramselaar Light Solutions
The Netherlands Institute for War Documentation (NIOD) is housed in a magnificent monumental late 19th century building at the Amsterdam Herengracht (the Netherlands). Recently, the unique brass chandeliers were provided with LED lamps, which were specially developed for this project by Ramselaar Light Solutions. Ron Ramselaar and M. Brouwers, advisor on behalf of the Government Buildings Agency (RGD), tell us about this extraordinary project.
Rich document application/x-troff-ms Human-Centric Lighting: Sensor Technology for Full- Spectrum Lighting Solutions by ams
While not necessarily common knowledge, research is rapidly validating the common-sense understanding that human beings are “tuned” to the natural lighting cycles of the sun, and can be equally “de-tuned”, to the detriment of both health and productivity, by artificial light sources that operate contrary to these natural flows. Sajol Ghoshal, Director of Sensor Driven Lighting at the Opto Sensor and Lighting BU at ams, discusses the available approaches for full-spectrum solutions, and potential humancentric benefits, of fully integrated intelligent ambient/color light sensor and driver technology.
Rich document Additive Manufacture of Optics Goes Digital by LUXeXceL B.V.
With a new technology for additive manufacturing, optics fabrication has gone digital, making more product innovation and variety affordable by eliminating the expense of molds and tooling, enabling just-in-time manufacturing and bringing a new freedom for optics and lighting designers. Marco de Visser, Business Development Manager at LUXeXceL B.V. gives an update on this technology and its new opportunities.

Rich document DC-Grids - Challenges and Chances for LED Lighting by the Fraunhofer Institute and LED professional
At the beginning of November many important aspects of DC Grids were discussed at the Fraunhofer Institute for Integrated Systems and Device Technology in Erlangen at the European Center for Power Electronics (ECPE) conference. Besides fundamental issues, very specific ones like how the introduction of DC Grids affects lighting technologies and especially LED lighting were part of the program. Below, Arno Grabher-Meyer from LED professional gives a summary of the speeches and expert discussions and gives us an idea of what the key ideas could mean to the LED lighting community.
Rich document Energy Efficiency and Thermal Simulations of a Retrofit LED Light Bulb by the University of Turku
Mika Maaspuro and Aulis Tuominen from the University of Turku investigated the energy efficiency of a LED driver mounted inside a retrofit light. The heat generation of the LEDs and the driver of the light bulb have been simulated and measured. A thermal model for the light bulb has been created and simulated using a Finite-Element-Method (FEM) software. Parameters of the model have been adjusted to match the temperature measurements which have been done with IR-camera and thermocouples.
