New Stray Light Correction Method Enables UV Hazard Measurements with Array Spectroradiometer

A new stray light correction method implemented in the BTS2048 UV array spectroradiometer now enables applications previously only possible with double monochromator systems. This novel method was presented at the CIE's 29th quadrennial session. It combines Out-of-Range and In-Band stray light correction techniques, thereby greatly increasing the dynamic range of accurate UV measurements. Read more »

Thermal and Optical Challenges for SSL in Automotive Applications

LpR 72 Article, page 50: 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 every few weeks new improvements are reported, thermal management remains crucial and a critical part of the system. Umut Zeynep Uras, Ahmet Mete Muslu and Mehmet Arik, from the Energy Efficient Electronics and Lighting Technologies Center (EVATEG), Department of Mechanical Engineering, College of Engineering at Ozyegin University, and Fatih Goren from the FARBA Corporation, explain the dependencies between photometric, electrical and thermal parameters of an automotive lighting application.

LED Lighting Systems in Smart Buildings with DC Microgrids

LpR 72 Article, page 60: While electric motors for ventilation and air-conditioning systems were already 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. Carsten Moellers from Abalight discusses a number of unresolved questions and presents possible solutions in this article. Read more »
