UL Helps Advance LED Lighting Innovations

UL, a leading global safety science company, today announced that its lighting laboratory in Carugate, Italy, located in metro Milan, has received accreditation from the Digital Illumination Interface Alliance (DiiA) to be a Digital Addressable Lighting Interface (DALI) protocol test house. As an international standard for a two-way communication system that brings digital technology to lighting, DALI defines the commands that LED drivers and ballasts need to recognize in order to communicate via controllers and computers equipped with appropriate software or building management systems. With the DiiA accreditation, UL now has the ability to test control gears and devices, such as push-buttons and occupancy and light sensors, against the DALI standard. Read more »

A New LED Controller Technology to Expedite the Next Level of Smart Lighting

Lighting installations that use artificial lighting and often deemed more comfortable and energy efficient are generally referred to as "Smart Lighting". While no clear definition exists "Smart Lighting" has become a common catch phrase. Kurt Marquardt, Senior Director LED Lighting Systems and Product Marketing, Infineon Technologies has a more accurate definition. For him, the term "smart lighting" describes the capability of the lighting system to adapt automatically to the needs of the users and the room. He presents an alternative way to implement smart lighting systems, using the new XDPL8221 digital LED-driver IC [1]. Read more »

Temperature Profiling of Secondary LED Optics by Infrared Thermography

Over the last few years, the power density of white LEDs has increased dramatically. Whilst there are large efforts to optimize the thermal management and thus the temperature stability of the LEDs, less attention is paid to the temperature of the secondary optic. Peter W. Nolte, Franziska Steudel, Bernd Ahrens, Nils J. Ziegeler, Frank Drees, Horst Rudolph, and Stefan Schweizer from the Fraunhofer Application Center for Inorganic Phosphors, the South Westphalia University of Applied Sciences, and the Innovations-and Technologycenter GmbH, TRILUX Group respectively, have approached this issue. They investigated the temperature profiles of polymethyl methacrylate (PMMA) and polycarbonate (PC) secondary optics and they discuss the results. Read more »

Delta Launches New EUCO Arena Sport Series LED Drivers for Reliable, Efficient Arena and Outdoor Lighting

Delta, a global leader in power and thermal management solutions, today announced the launch of EUCO Arena Sport Series LED drivers, which are designed to provide luminaire manufacturer's a versatile solution for many industrial and commercial lighting applications such as high mast lighting, recreational sports lighting, harbors, airports, and parking lot lighting. Built on three independent output channels with a maximum power of 500 W (1500 W total), these drivers have a wide operating temperature range that ensures performance and reliability for the most rugged applications. These drivers offer precise tuning of the drive current and are equipped with dimming circuitry for DALI-2 digital dimming to allow for adjustment of lighting levels from 0.1% to 100%. In addition to the driver architecture and circuit topology, Delta has achieved a very low typical current ripple of ≤1% peak-to-peak. That is important when it comes to televised events, since current ripple can cause LED flicker. Flickering lights affect the quality of sports broadcasts and limit slow motion options. Read more »
