Lighting : LIGHTING August-September 2017
44 LIGHTING MAGAZINE | August/September 2017 August/September 2017 | LIGHTING MAGAZINE 45 INVESTEC AND BAIN CAPITAL CREDIT INVEST IN STRONG FUTURE FOR GERARD LIGHTING Leading Australian lighting company, Gerard Lighting, has reaffirmed its plans for growth following an agreement with a consortium led by Investec and Bain Capital Credit to assume full ownership of the business from CHAMP Private Equity. The acquisition, led by two of Gerard Lighting’s long-standing investors, will ensure a strong and stable future for the business, significantly reducing debt levels and enabling the redeployment of capital towards growth opportunities across its key market segments. The consortium will invest new capital into the business as part of the agreement. The company’s CEO, Les Patterson, said that the new ownership model was a clear vote of confidence in the business, both for its strong market position and its significant growth potential. The change of ownership is expected to result in changes to the composition of the Gerard Lighting Board, with new appointments to be announced in due course. IES UPDATES+POSTS In 1979, Craford began work at Hewlett-Packard, where his team pioneered the development of AlInGaP LEDs using metalorganic chemical vapour deposition (MOCVD), a relatively expensive low-volume process that had not been utilised for the high volume commercial production of LEDs. AlInGaP LEDs increased the performance of red and yellow LEDs 10-fold. Craford’s team continued to achieve technology breakthroughs in AlInGaP LEDs, eventually reaching 100lm/W. The impact of Craford’s early work is today visible in the colour LEDs now ubiquitous in applications such as traffic signals, emergency and automotive lighting. His later work focused on making white LED light cost effective for retail, office, architectural, outdoor and industrial lighting markets. In the early 2000s, his team’s work enabled commercialisation of the first high- power LEDs in the 10-20 lumen range. Such LEDs contributed to the creation of the first LED bulbs to meet the high efficiency and long lifecycle requirements to win the US Department of Energy’s L Prize for a 60W-equivalent LED bulb. Today, Craford is Lumileds’ Solid State Lighting Fellow at the company. He is also an IEEE Life Fellow and a member of the National Academy of Engineering. He has received numerous awards including the 2002 National Medal of Technology and the 2015 US National Academy of Engineering Charles Stark Draper Prize. LED and solid state lighting pioneer Lumileds has announced that George Craford, the Lumileds Solid State Lighting Fellow, has been awarded the IEEE Edison Medal for his “lifetime of pioneering contributions to the development and commercialization of visible LED materials and devices”. He was presented with the medal at the IEEE Honors Ceremony in San Francisco on May 25, 2017, during the IEEE Vision, Innovations, and Challenges summit. Craford’s career spans from the early days when LEDs were first developed to the production of high-brightness LEDs suitable for commercial use in a variety of applications, including LED bulbs. Even today, Craford is probably best known for his invention of the yellow LED in 1972. Following that milestone, he then led the development of increasingly brighter red, orange and amber LEDs.

(IEEE) Relying on tunable white light “is the best, most-affordable way to ‘future- proof’ your work and designs and ensure very high performance.” So said Terry Clark, Founder and Chairman of the Board of Finelite Inc, while participating in the National Lighting Bureau’s Annual Lighting Forum as one of three panellists focused on new and emerging developments in tuneable white light; ie, lighting whose colour and other elements can be adjusted to meet a variety of needs and preferences. Other panelists included Brent Protzman, Director of Building Science and Standards Development, Lutron Electronics and Sandra Stashik, Director, Strategic Specification Development, Acuity Brands Lighting. EdisonReport Editor and Publisher Randy Reid moderated the discussion. Three types of tuneable white light are now available, Mr Clark pointed out: dim-to-warm lighting, meaning light-emitting diodes (LEDs) that mimic incandescent lighting, in that their colour output becomes warmer as they are dimmed; two-colour-white lighting that mixes cool-white and warm- white light; and precision lighting that can require as many as seven LEDs. Ms Stashik noted that, right now, dim-to-warm LED lighting seems the most popular, in part because it is the least expensive form of tuneable white light and its control systems are relatively simple. Nonetheless, more robust tuneable systems with simplified controls are now a reality and more are under development. Their application will likely accelerate when reports quantifying their benefits are published. One of the most important applications for tuneable white light will occur in health-care facilities, especially for patients dealing with dementia and Alzheimer’s Disease. By using light as a stimulant during morning hours, patients will nap less during the day, enabling them to sleep better at night. SOCIETY OF LIGHT AND LIGHTING PUBLISH NEW LIGHTING GUIDE GEORGE CRAFORD AWARDED IEEE’S EDISON MEDAL FOR CONTRIBUTION TO LED LIGHTING. DESIGNING WITH TUNABLE WHITE LIGHT IN FOCUS AT THE US NATIONAL LIGHTING BUREAU’S ANNUAL LIGHTING FORUM Using light in this way can also reduce the patients’ agitation. In commercial applications, tuneable white light can be used to affect the colours of surfaces in a space. This gives building owners the ability to provide lighting that is highly compatible with a given tenant’s interior design, and to adjust the lighting to make it ideally suited for the next tenant’s interior design, avoiding the need to replace the existing system for each new tenant. The Designing with Tunable White Light discussion can be viewed at https://nlb. org/designing-with-tunable-white-light/. The Society of Light and Lighting (SLL) has published a new introductory guide to lighting. LG0: Lighting Guide 0: Introduction to light and lighting is based on chapter one of the forthcoming, updated edition of the SLL Code for Lighting. It has been produced as a free, stand-alone document as an introduction to light and lighting for those with a general interest in the subject. The guide looks at the issues affecting the quality of lighting and task performance, as well as how light affects people’s behaviour, safety, and perception of objects and space. The final sections focus on lighting and health, as well as cost and pollution issues. The guide is available on the CIBSE Knowledge Portal.
