Today, 30-50% of workers are over 45 years old. Over the age of 45, people begin to experience a deterioration of their near-sight vision. Research shows a 60-year-old person needs between two and five times as much light as a 20-year-old to see the same visual detail, let alone concentrate.
As a result, Philips Lighting believes office lighting needs a serious rethink at a policy level.
In Europe, the minimum lighting requirements for writing, typing, reading and data-processing in offices is 500 lux, but Philips has gathered research to show that this is not considered sufficient by almost a third of today’s global workforce.
The answer may not be to simply increase light levels. The same lighting that boosts concentration for one employee could damage the creativity of another, says Philips. A laboratory study from 2011 demonstrates that while 1000 lux is required to support concentration, it is dimmer lighting that enhances creative thinking.
Philips says the solution is personalized lighting in the workplace.
In 2013, the company conducted a survey among people who tested a desk lamp that allowed them to adjust its light intensity and color temperature according to personal preference. Some 90% reported sharper vision, optimum eye comfort, the ability to see smaller details and improved contrast. The ability to adjust individual workplace lighting conditions according to personal preferences has been associated with better mood, improved lighting quality ratings and environmental satisfaction. Because individual preferences vary widely, individual control is the only practical means to ensure that people have a good chance to obtain light that is best suited to them.
“Regulatory bodies should take these findings into account for the well-being and productivity of today’s workforce,” says Dr Bianca van der Zande, Principle Scientist at Philips Lighting. “People spend 80-90% of their time indoors from which around 20% is spent at work so the indoor environment determines to a large extent the comfort and wellbeing of the office employee, influencing their performance. It is important that human-centric lighting becomes a part of the regulatory standards, allowing architects and building designers to advise for the best solutions – not only for offices, but for all building environments.”

Lutron Electronics has made the sad announcement that Joel Spira, the company’s Chairman, Founder, and Director of Research, passed away on Wednesday, April 8, 2015.
Starting from a Riverside Drive ping pong table in New York City, Joel and his wife Ruth founded a company that now sells lighting controls, motorized shades and temperature controls that are used in residences, palaces, offices, hotels, museums, and other venues in over 100 countries.
Susan Hakkarainen, Joel’s daughter and Senior Vice President at Lutron said, “He was a wonderful husband, father, grandfather, and friend, and considered every employee to be part of his extended family.”
Spira formed Lutron Electronics in 1961 to market his invention of the first solid-state dimmer for incandescent lighting. Under his 54-year leadership, Lutron has developed products to control all types of lamps, including LEDs as well as shade and temperature controls. As recently as Tuesday evening, Joel was actively working with a team of engineers on the new Lutron Caséta Wireless smart home system, which includes dimmers, switches, thermostats and window shades that can be controlled from the Apple iPad, iPhone and Android devices.
Spira graduated from Purdue University in 1948 with a Bachelor of Science degree in Physics. Since then he has received honors and distinctions too numerous to list. In 1995 he was cited as one of Purdue University’s “Distinguished Graduates for Outstanding Invention”, and received the Leonardo DaVinci Award from the American Society of Mechanical Engineers in 2000.
Spira is a member of the National Academy of Engineering (NAE) and a fellow of the Institute ofElectrical and Electronic Engineers (IEEE). He has received honorary Doctorates from Lehigh University, Muhlenberg College, and Purdue University.
Spira served on advisory boards and councils, and he and Ruth supported Excellence in Teaching awards at Carnegie Mellon University, The Cooper Union, Cornell University, Georgia Institute of Technology, Lehigh University, M.I.T., Muhlenberg College, Penn State University, the University of Michigan, the University of Notre Dame, and his own Purdue University.
U. S. Representative Charlie Dent offered this tribute, “Joel Spira was a giant of American Industry – an Edison-like inventor and a great man very much dedicated to his family, company, employees and community. I have known Joel for over twenty-five years. He was a larger-than-life figure to me. I’m deeply saddened by his passing and my family’s thoughts and prayers are with Joel’s family and friends. Joel invented the dimmer, but his memory will always shine bright.”
High-bay lighting must meet the stringent demands of illuminating spaces from afar while minimizing contrast, reducing glare, and in many cases meeting strict safety and hazardous environment requirements. Until very recently, LED technology was not able to meet these requirements, at least not at a reasonable price.
In 2013, however, several high-bay LED products were launched that provide exceptional quality in a price range that allows for acceptable paybacks from energy savings. The high-bay lighting market is set for a rapid shift in lighting technology, similar to the shift toward LED lighting that has already begun in commercial buildings, according to a 2014 report by Navigant Research.
Concurrent with the transition in lamp technology, more high-bay lighting systems are beginning to incorporate sensors, networked communications, and other advanced lighting controls to further reduce energy consumption and improve functionality. The falling prices of LED luminaires and lamps, as well as sensors and controls, are driving their adoption within high-bay applications.
Due to the high wattages and long runtimes of these lights and their attractive payback periods, they are excellent candidates for upgrades. However, average selling prices (ASPs) will continue falling and lamp replacement sales will begin to slow as the installed base of long-life LED lamps grows. Navigant Research forecasts that global sales of high-bay luminaires and lamps will peak at almost $17.0 billion in 2017 and then decline to $15.9 billion in 2021.
This Navigant Research report analyzes the global market for high-bay lighting in the following five building types: warehouse, industrial, gymnasium and indoor sporting facilities, high-bay retail, and transportation. The study provides an analysis of the significant market drivers, trends, and opportunities associated with luminaires, lamps, and networked lighting controls in these high-bay applications. Global market forecasts for unit sales and revenue, segmented by lamp type, building type, and region, extend through 2021. The report also examines the major technology issues and trends related to high-bay lighting and profiles the key industry players in this market.

The LED revolution is spawning another revolution in lighting controls that promises similar potential to transform both the traditional lighting industry and how we illuminate the built environment.
Many commercial building energy codes now require automatic shutoff, multilevel control and daylight harvesting, with a general trend toward flexibility both in control zoning and luminaire light level reduction. LED lighting is highly compatible with lighting control. LED luminaires are typically offered with dimming standard or as an option.
“The instant-ON and dimming capabilities of LED lighting give end-users unprecedented control over the environment,” says Tom Hinds, Product Portfolio Manager, Cree, Inc. “They can adjust light levels and increase the energy savings by dimming in response to daylight or building occupancy.”
As control becomes increasingly important, a number of lamp and luminaire manufacturers, either on their own or by partnering with a control company, have begun integrating control devices within their products. Examples range from the basic, such as a standalone LED wallpack with an integrated motion sensor, to sophisticated systems integrating multiple sensors into luminaires and then tying these luminaires together within an intelligent control network for lighting management across a room or facility.
“The rapid adoption of LED lighting in both new construction and retrofit applications comes at the same time energy codes are becoming more stringent,” says Audwin Cash, Vice President – Acuity Control Solutions, Acuity Brands Lighting. “It is natural for customers to find ways to marry the two for increased simplicity and cost savings. As manufacturers, we want to make it easy for our solutions to be deployed, and there is nothing easier than having installers connect controls into the system by simply connecting the hot, neutral and ground on a luminaire.”
For the designer, there are fewer items to consider, as sensors are integrated into the luminaire, eliminating power and controls wiring. There is also peace of mind that they are specifying a proven system known to be compatible and from a single manufacturer. For the installer, there are fewer devices to install and coordinate placement, potentially reducing installation time. For the distributor, luminaire-integrated controls can simplify the solution and reduce the number of devices needed.
“Overall,” says Cash, “integrated LED lighting and control can mean less coordination between vendors on projects, fewer purchase orders and fewer phone calls to track down missing shipments. With one vendor responsible for the system, you can eliminate a lot of coordination and waste associated with project management of separate systems.”
The most powerful options available today consist of intelligent luminaires with onboard sensors that are tied together in a communication network that may be hardwired or wireless.
Brian Bernstein, Global Head of Indoor Lighting Systems, Philips Lighting, says intelligent LED lighting systems with integral controls should be regarded as having a local and application layer. The local layer represents each luminaire’s “reflexes,” such as dimming in response to available daylight. The application layer covers lighting management activities that occur across the application and the collection of data that can be fed into a database for analysis using software. For example, a municipality could install streetlights with luminaire controls for ON/OFF at the local layer while collecting data at the application layer for energy analysis and maintenance.
Going further, intelligent lighting permits a vision of the lighting system as a platform that combines a network of intelligent luminaires with additional sensors, controls and software providing capabilities that go beyond illumination.
“LED luminaires with integrated controls may offer a range of additional capabilities,” Bernstein says. “Some communicate information about their own status and operations—including internal operating temperature, energy metering and lifetime monitoring—that lighting systems owners and managers can use to optimize system performance, efficiency and maintenance. Other LED luminaires use integrated sensors to collect information on usage and environmental factors in illuminated spaces, such as occupancy levels and activity patterns, temperature/humidity changes and daylight levels. If the lighting system is integrated with a lighting management software platform on the back end, system owners and managers can store, visualize and analyze historical information about luminaire performance and activities in illuminated spaces for decision support, greater insight into worker/customer behavior and enhanced facility management.”
The latter envisions lighting, an electric lighting system prevalent in every building, as a delivery point for an Internet of Things—LED lighting as advanced digital building infrastructure capable of collecting data, delivering information to occupants or both. Bernstein sees this as the future of lighting in many buildings.
“In general, the market share for intelligent luminaires is relatively low today but is expected to be much higher in five years,” says Jonathan Weinert, Strategic Content Development for Connected Lighting Systems, Philips Lighting. “Within that timeframe, we anticipate that the market will reach a tipping point, with the center of gravity shifting from analog or load-based control to digital control, profoundly affecting the lighting industry from end to end. Once this transition is complete, we expect the lighting industry to look much more like the electronics and IT industries rather than the traditional lighting industry of the last 100 years or so. This transition has already started to occur.”In the interim, he says, it’s practical to regard applications as individual spaces with individual control needs. In some, traditional lighting may be sufficient, while in others, such as highly occupied spaces such as offices, can benefit from intelligent lighting. This hybrid system can be integrated using a gateway or other integration method.
Industry changes may include new business models focused on services and support, with new players taking a more active role in lighting decisions. “The more connectivity you have with the lighting and intelligence embedded in luminaires, the more critical it becomes to have software to manage and magnify the benefits of these systems,” Cash says. “For traditional lighting manufacturers, some of these changes afford new business models around services and support that allow end-users to get maximum benefit with significantly lower cost of ownership. Traditional lighting, lighting control and HVAC providers will certainly be involved. As luminaires collect and manage increasingly more data, we will see new players in the networking, data, advertising, mobile marketing and security space take more active roles in selecting lighting.”
For distributors, intelligent lighting control offers ongoing opportunity in their lighting business, but education is key.
“Keep learning and experiment with the technology,” Cash advises. “This is an extremely dynamic category advancing at a rapid pace. We will be challenged to rethink our role in the construction process as luminaires become more intelligent.”
“In both LED lighting and lighting controls, distributors should look for high-performance products that are easy to use, reduce maintenance and energy costs, without forcing end-users to compromise on light quality or performance,” Hinds says.
