DECORATIVE LED LIGHTING FOR BUSINESS PARK IN KITWE

T he ECLBusiness Park inKitwe,Zambia,is the city’s newest Office and Business Park. It is a mixed-use development comprising shopping centre, hotel, convention centre and an office block. BEKA Schréder supplied various decorative LED lighting solutions for the prestigious project. The advantages of LED technology are well known and include reduced energy consumption – which leads to significant energy savings compared to traditional light sources – and low maintenance requirements, which offer a fast return on investment. ZELA post top luminaires have been installed in the parking area of the hotel. They emit a pleasant, glare-free light by night, and lend an elegance to the area by day. BEKA LEDpost bollards illuminate the walkways leading to the buildings, and their distinct design is perfect for the setting. In addition, no spill light is emitted in an upward direction, ensuring that there is no light pollution. The main entrance to the hotel is illuminated by the ILUMup, a versatile in-ground uplight. The ILUMup offers a wide range of photometric distributions for all types of illumination, such as lighting façades, highlighting architectural details and uplighting trees. The façades of the buildings are accentuated by BEKA LEDduo up- and downlighters – they are robustly

constructed, weather proof, hail proof, and corrosion proof, ensuring a long lifetime. LEDflood high-efficient floodlights are installed in the outdoor parking area of the shopping centre to create a safe and welcoming experience for visitors. CITEA LED decorative streetlights have been placed at the shopping centre entrance, while the spiral driveway to the covered parking area is

illuminated by the BEKA SERIES 31 LED bulkhead. BEKA Schréder locally develops and manufactures LED lighting products, which are designed and suitable for local conditions. The company worked with Bicon Consulting Engineers, WSP, and RM Consulting to provide a successful, energy- efficient LED lighting solution for this prominent project.

RS Components has announced the availability of a range of LED-based products that use new technology to deliver a quality of illumination that is natural looking and designed to be virtually indistinguishable from sunlight. The ‘SunLike’ LED range from Seoul Semiconductor has been developed as a natural-light LED that is optimised for human-centric lighting. SunLike contributes to the improvement of human health (including sleep quality and prevention of eye fatigue and myopia) by providing healthy light for the stabilisation of human biorhythms. Essentially, SunLike removes the high-energy short-wavelength blue LED light source and replaces it with a purple-light LED chip, which is based on the combination of Seoul Semiconductor’s patented LED chip technology and innovative TRI-R phosphor technology from Toshiba Materials. Having won numerous awards worldwide, the SunLike LEDs also triumphed at the recent Lux Awards 2018 in the ‘Enabling Technology of the Year’ category, which rewards exceptional technology developments in various fields including light sources, drivers, optics, thermal products and innovative materials. A key element of the SunLike technology is the realisation of true natural colour with an excellent colour reproduction ratio (CRI) that is similar to sunlight. It scores a sunlight spectrum concordance rate of 94%. In addition, SunLike LEDs offer high clarity and a dimensional sense to objects and text with glare-free illumination, making them an ideal technology for deployment in backlighting applications and touchscreen interface development in particular. RS stocks a range of Seoul Semiconductor SunLike LEDs with warm-, natural- and cool-white colour temperatures, including 2700 K, 3000 K, 3500 K, 4000 K and 5000 K specification devices.

WHAT TO CONSIDER WHEN BUYING LED FLOODLIGHTS

L ED floodlights are perfect for security, outdoors activities and saving on en- ergy costs. Although they are versatile, people often have questions about LED floodlights, and Nordland Lighting has compiled a few points to consider when shopping for LED floodlights. LED floodlights can be used both domestically and commercially. The most attractive quality they have is that they give you an amount of light equivalent to that of numerous bulbs, but they consume less energy compared to halogen floodlights. It is also important to note that they are built to last 50 000 hours, which is much longer than the halogen floodlights. Other than energy saving, they also have motion sensors and timers, and buyers can choose fromportable to solar floodlights options. When choosing the brightness of floodlights, there are a few things to consider: Location: It is important to put the area you intend to light up into consideration. Consider that LED floodlights can be intrusive to neighbours and that they can distort the vision of oncoming drivers. Generally, pointing floodlights downwards at
