Lighting : LIGHTING August-September 2017
46 LIGHTING MAGAZINE | August/September 2017 August/September 2017 | LIGHTING MAGAZINE 47 NASA’s Juno mission to Jupiter has returned a set of extraordinary images that shed new light on the giant gas planet – thanks in part to the optical, ultraviolet and infrared sensors on board the spacecraft. Launched in August 2011, Juno arrived in the Jovian orbit almost exactly five years later and has since flown to within 4200km of the planet’s vast, swirling, atmosphere. Data collected by JunoCam and other instruments and now published in more than 40 different journal papers, was said to have thrown scientists a “curveball”. The space agency says that the assumption-challenging findings are largely provided by the JunoCam imagery, which have provided close-up views of Jupiter’s poles for the very first time. They show several enormous, swirling, storms – each larger than Earth – clustered together closely. Scientists were puzzled as to how they could be formed, how stable the configuration is, and why Jupiter’s north pole doesn’t look like the south pole. Aside from JunoCam, the probe’s instruments include ultraviolet and infrared imagers and spectrometers, as well as a six-wavelength microwave radiometer for atmospheric sounding. Several non-optical pieces of equipment are able to monitor charged particles, gravity and Jupiter’s huge magnetic field. While JunoCam has provided the most striking imagery, Juno’s UV and IR imaging tools have also captured new, high-resolution views and spectra of the planet’s northern and southern aurora, from directly above the respective poles. The IR aurora is thicker on the dusk side of the planet and thinner on the dawn side, as in UV. It was also possible to discern effects related to the moons Ganymede and Io. Scientists didn’t have to wait long before more intriguing results are collected: Juno’s orbit is scheduled to swing the craft close to Jupiter’s atmosphere every 53 days and the instruments were pointed at the famed “red spot”, on 11th July. SolarPower Europe has launched the Global Market Outlook for Solar Power 2017-2021. The report confirms that 2016 was another record year for solar, with global annual solar additions growing by 50% with 76.6 GW installed. There is now a total worldwide solar power generation capacity of 306.5 GW. For the first time, solar left behind its renewable energy peer, wind, in terms of annual installations. When looking at solar, the cost reductions experienced and predicted outstrip all other power generation technologies. Today, utility-scale solar is already cheaper than new gas, coal and nuclear power plants. The quickly decreasing cost of solar continues to improve its competitiveness and is a major driver for solar’s global success story. All solar tenders awarded since 2016 are lower than the price guarantee the UK government signed for the Hinkley Point C nuclear power plant Juno’s red-green-blue-methane (890nm) filtered JunoCam instrument captured this view of Jupiter’s south pole. Taken from an altitude of 52,000km, it shows giant cyclones measuring up to 1000km in diameter. Multiple images taken with JunoCam on three separate orbits were combined to show all areas in daylight, enhanced colour and stereographic projection.

NEW VIEWS OF JUPITER’S POLES PROVIDED BY SENSORS ON BOARD NASA CRAFT SolarPower Europe predicts a possible 1 Terawatt of photovoltaic (PV) generating capacity by 2021. PLANNING BEGINS FOR THE FIRST INTERNATIONAL DAY OF LIGHT IN 2018 SOLAR POWER: 2016 WAS ANOTHER RECORD SOLAR YEAR AND DEMAND SHOULD CONTINUE TO RISE last year. A new world-record low 25-year solar power supply contract was awarded in Abu Dhabi in 2016 for 24.4 USD/MWh (2.4 US cents/kWh).

With an ultimate focus on providing an outstanding user experience, the Gerard Lighting Specifier Website will offer lighting consultants, architects and specifiers quick and easy access to lighting solutions, case studies, critical product information and insights into lighting trends. Co-created with a wide range of customer groups across the industry providing feedback through informal focus groups and discussions, the specification website brings together the preferences of users. From development to refining, the process of customer consultation has helped shape and guide, enabling Gerard Lighting to introduce a new platform that truly understands and caters to the needs of all customers. The website will allow users to choose solutions by segment, allowing quick and easy specification in a variety of different project areas, the ability to view product information by clear and defined product categories, easy access to details on completed Gerard Lighting projects and the ability to keep up to date on global and local trends that influence lighting design and specification. “We’ve designed this new destination for customers to cut through the clutter and directly find the information relevant for them. If a hospital administrator or specifier is on the site, they can navigate straight to the healthcare tab and be presented with a comprehensive list of applicable lighting solutions specific to that vertical,” said Ben Mills, General Manager at Gerard Lighting. To add another point of differentiation, specifiers can toggle between ‘good’, ‘better’ and ‘best’ tabs to offer a tiered lighting solution based on desired outcomes and budgets. “Encouraging efficiency and providing enhanced user experience has been our core goal in the development of this website. We want specifiers to leave the platform with complete lighting solutions and feeling well-informed and inspired,” continued Mills. For each segment, Gerard Lighting operates in, information on trends and thought leadership will be shared, to not only tell the Gerard Lighting story, but to impart the institutional knowledge acquired as a result of the company’s longstanding history in the industry. This new look, refined website features a comprehensive library of photometrics for specifiers to download IES and REVIT files, providing a one-stop shop and much needed time saver during the design process. To further demonstrate the commitment to well thought out design and usability, the complete Gerard Lighting IT system has been integrated with the website. In addition to maximising data accuracy, this means that any relevant product updates made internally, are automatically transferred to the website in real time. The future of Gerard Lighting still has much to offer. With $500k invested on technological platforms, the company is looking to increase its presence on social media and bring new tools to the customer. These innovative offerings will allow specifiers to mix and match components and build products online. Gerard Lighting Specifier Website: http://specify.gerardlighting.com.au Following the highly successful International Year of Light and Light-based Technologies 2015, the Executive Board of UNESCO (United Nations Educational, Scientific and Cultural Organization) has endorsed an annual International Day of Light. The purpose of an International Day of Light will be to provide an annual focal point for the appreciation of the role that light plays in the lives of the citizens of the world in areas of science, culture, education, sustainable development, and in fields as diverse as medicine, communications and energy. The broad theme of light will allow many different sectors of society to participate in activities around the world to raise awareness of science and technology, art and culture, and their importance in achieving the goals of UNESCO – education, equality and peace. The International Day of Light will be proclaimed at the General Conference of UNESCO in November 2017 and the first celebration will take place on 16 May 2018. Partners around the world are now beginning ambitious plans for a wide range of local celebrations and activities to raise awareness of the many different ways light impacts society. In addition, an official inauguration ceremony will take place at the headquarters of UNESCO in Paris in the afternoon and evening of 16 May 2018, involving presentations from Nobel laureates and other scientists, industry leaders, as well as a wide range of other partners from sectors including art, architecture, lighting, design and NGOs.
