LEDVANCE expands LED strip systems and services
L
EDVANCE’s expanded range of tailored lighting applications combines wide product choice with smooth customer service. New Tunable White, RGBW and RGB LED strips, as well as LED drivers, provide installers with an exciting scope of products to choose from, with clear product classification into Superior, Performance and Value simplifying the search. In addition, LEDVANCE offers technical, planning and installation support with an online LED Strip configurator and comprehensive training platform. The extended range is available for wholesalers from September 2020. The system with dynamic LED strips now features RGBW and RGB versions, letting users effectively create accents in any ambience. With Tunable White, it is easy to switch between activating light for work and atmospheric warm light. The system solutions, consisting of flexible LED strips, drivers and accessories, can be easily configured, combined and installed. They come with up to five years guarantee. The new DALI-2 drivers now support a greater range of combinations and applications. They can accommodate large installations, such as illuminating entire shopping centres, offices and hospitality facilities, or they
can simply light up stairwells, book cases or showcase retail products on shelves. Installers benefit from additional support like the quick and intuitive LED Strip System Configurator online. In just a few quick steps, they can define the lighting requirements
In addition to the online configurator, LEDVANCE offers a new, intuitive
online training portal for lighting projects featuring a variety of application-oriented eLearning courses. Installers can register at
training.ledvance.com and directly benefit from the training.

(e.g. length to be illuminated, light colour and brightness), mounting type (indoor / outdoor for IP protection), accessories, operating mode and drivers. The configurator then automatically generates an overview with all the necessary components and useful information about mounting. Following the option to manually adjust the items on the list, the installer can directly order the parts.
The LEDVANCE LED strips are available in three different categories: the Superior Class contains the highest quality products for professional and industrial applications. This includes major and prestige projects for indoor, outdoor and wet areas, as well as applications exposed to salt mist and high levels of UV. The Performance Class is the core portfolio for high-quality demand-based products. Its products are the solution for the majority of lighting needs. They are suitable for semi-professional
applications like minor projects for indoor, outdoor and wet areas.
Value Class offers a good combination of strong performance and attractive prices. General applications include small, semi- professional lighting projects for indoor, outdoor and wet areas. The product range also includes different profiles, covers and LED drivers to various accessories, control units, touch panels and remote controls for dynamic LED strips. All LED strips are pre-wired on both sides and are easy to shorten, if necessary. All components are perfectly matched to one another but can also be combined with most products from other established manufacturers. The product range of the LEDVANCE LED Strip System covers a wide variety of requirements and can be used as a component in almost every lighting project. LEDVANCE lighting solutions come in environmentally friendly cardboard packaging with all relevant product information immediately visible on the outside of the box.

cientists have combined experimental data gathered at the Canadian Light Source at the University of Saskatchewan and
theoretical data to build deep insight into two types of light emitting crystals for next-generation LEDs.
“When we have means of creating more efficient lighting, this has a huge environmental impact,” says Alexander Moewes, Canada Research Chair in Materials Science with Synchrotron Radiation at the University of Saskatchewan, who cites that lighting accounts for 15-20 per cent of global electricity consumption, and therefore for roughly 5 per cent of worldwide greenhouse gas emissions.
His work to improve LED technology focuses on finely tuning and

understanding the effect of different crystals in LED phosphors to get precise performance properties, including colour and amount of light output. “Getting these properties right is important, since our eyes are incredibly sensitive to the colour of light, whether it is too green or red,” explains Moewes. Moewes and Ph.D. student Ruhul Amin
Their most recent publication in Advanced Optical Materials lays the groundwork for informed design of LED materials, the direction Moewes hopes to move the team’s work towards. All energy levels, band gaps and luminescence wavelengths were measured at beamlines at the CLS. The band gap was also confirmed by calculations.
“We now study how different host crystals affect performance. We want to go the other way and design them through informed decisions guided by our calculations before the material is synthesised,” he says. Their calculations are a key part of the team’s success, along
with the use of cutting-edge experimental techniques. The comparison of real- world measurements enabled by custom built experimental tools at CLS and their calculations provides more detailed insight. The equipment they built at the REIXS beamline at CLS for this work allowed them to specifically look at the energy levels within europium and when light is released because electrons transition in the material between energy levels. The Moewes team was the first to devise a technique to take these measurements. Armed with this information which confirms the power of their predictive models, the group can begin the work of designing finely tuned crystal structures for low energy loss, high output, perfectly tinted LEDs for lighting applications.
