Scott Wade, Technical and Certification Manager, DiiA

Dr. Scott Wade has been Technical & Certification Manager for DALI/DiiA since August 2013, and for around 14 years has been an industry expert member of the IEC 62386 standardization team. At LpS 2018, we talked about the new DALI-2 standard and how it is different to DALI version 1, which changes are relevant for users, what DiiA is planning for the DALI-2 certification in the future, and what makes DALI-2 future proof.

Semi-Empirical Characterization of Freeform Microlens Arrays

Microlens arrays (MLA) have been used for imaging and non-imaging applications for a long time as cost-effective solutions. Non-symmetrical beam shapes require more advanced non-symmetrical freeform microlens arrays (FMLA). The required FMLA molding tools convey a high cost and an iteration process is required for the final design. A method to overcome these limitations based on 3D surface sampling, computer generation of a ray-traceable model and ray-tracing performance simulation is proposed and demonstrated for several commercially available freeform asymmetric thin-film diffusers.

Thermo-Optical Design Approaches in Automotive Lighting

Solid State Lighting changed the lighting environment in automotive lighting almost more than in the field of general lighting. While efficiency of the devices increased and new improvements are being reported, thermal management remains a critical part of the system. The authors explain the dependencies between photometric, electrical and thermal parameters of an automotive lighting application.

Shared Office Space – Intelligent Solutions for Future-Proof Building Usage

Shared office spaces are gaining popularity as a flexible, resource-efficient and creativity-inspiring way to work. The dynamic nature of such office spaces requires building automation and lighting control solutions that can quickly be deployed and easily be adapted to new office layouts. This article takes a look at different connectivity architectures (wired, wireless, hybrid) and protocols (Bluetooth, ZigBee, EnOcean, PoE) to assess their usability and show how minimizing the need for maintenance is a key for increasing profitability of service-based offerings.

LED Lighting Systems in Smart Buildings with DC Microgrids

While electric motors for ventilation and air-conditioning systems were DC-based in the past, powerful IT systems, LED lighting systems, photovoltaic systems with batteries and charging systems for electro mobility are now increasingly being used in modern building environments. They all need direct current (DC). Therefore, an obvious step is to equip modern buildings with DC grids. A number of unresolved questions will be discussed in this article and possible solutions will be presented.
