Havells presented “Spotlight Series” organised by Realty+ Masterclass featured Dr. Karsten Ehling, Founding Partner & Managing Director, Lichtvision Germany who elaborated on the latest trends of automation that are transforming the lighting industry.

Dr. Karsten Ehling an expert on the use and analysis of daylight in architecture was joined by Sudeshna Mukhopadhyay, Vice President, Havells India Ltd., an experienced consultant in lighting technology, application, design and end user research in India & Asia Pacific in the discussion on the current shifts in lighting design and applications.

Dr. Ehling was of the view that organizations are now more inclined to consider operating costs rather than the capital expenditure on lighting systems in commercial establishments. “Globally, Lighting as a Service (LaaS) model in which light service is charged on a subscription basis rather than via a one-time payment by specialized service provider is becoming popular. It includes light design, financing, installation, maintenance and other services. Appropriateness of lighting solutions against sustainability and Cradle to Cradle approach for lighting systems are some of the themes, lighting designers are working on now. Software enabled lighting controls are in the trend and energy-efficiency & convenience are the factors driving ‘On Demand’ solutions for lighting in commercial spaces,” he said. 

Dr Ehling highlighted the following macro trends in lighting: 

Workspaces: Smart/connected lighting with sensors and controllers that are networked (wired/wireless) is a trend that is evident in office lighting as it provides opportunities for better lighting, increases comfort, productivity and energy efficiency. Due to the pandemic, home offices are now prevalent for WFH which too requires well designed lighting for user comfort. Thus flexible lighting systems with wireless controllers for homes are in demand these days.

Shopping: In retail sector Amazon and other e-commerce platforms have revolutionized offline shopping as well. Iot Based lighting offers, lighting-based indoor positioning system, asset tracking for critical assets tagged with sensors, monitor conditions for perishable goods and space utilization. 

Hospitality: In hospitality sector, LED light fixtures and lighting controls play a pivotal role in crafting memorable experiences from personalized room lighting setting through guest smartphone, multiple sensor information for indoor navigation, monitoring of room quality parameter, use of amenities processed to optimise guest comfort and convenience as well as use of Li-Fi – short for Light-Fidelity – a wireless communication technology that utilises light to communicate and exchange data between connected devices.

Retrofitting: In the wake of the pandemic, homes and office owners are considering installing touchless lighting controls for contactless operations. This offers a perfect opportunity to retrofit smart lighting solutions as many of the lighting systems in current buildings are not energy efficient. The ideal solution for simple and flexible installation, easy programming and a one-touch centralised control panel is offered by RFID system made up of a series of wireless transmitters, receivers and combined units.

“Software enabled lighting controls and IoT evolution will be a game changer in the world of lighting and will ultimately transform the industry and lighting designers will drive the entire chain of lighting infrastructure while, adding health and well-being in it.” Dr. Karsten Ehling


Sudeshna Mukhopadhyay, Vice President, Havells India Ltd was of the view that the pace of lighting technology development varied from country to country.  She said, “The adoption of lighting technology is different in various countries. With rapid infrastructure development in India, government has now moved to using LED lights in public spaces that are also IoT connected and thus energy efficient as they can change temperature as per the time of the day.” 

According to Sudeshna, connected lighting is dependent on other infrastructure such as telecom and BMS and thus requires synergies among various professionals apart from the architect and lighting designers. Dr. Karsten concurred that with the advent of IoT, also comes the challenges of interoperability, scalability and cyber security which are still being worked upon by various industry professionals.

Sudeshna Mukhopadhyay emphasized the need to embrace new technologies in infrastructure lighting systems that can not only offer security and energy efficiency but also set the path for deploying future smart solutions. “High-quality, intelligent lighting helps make a city safer and more attractive.”

Dr. Karsten Ehling stated, “Lighting will play major in future when it comes to automation and optimization of buildings and cities. For instance, UV-C lighting is one component that has grabbed much attention. It is powered by Ultra-Violet radiation that functions to disinfect surfaces within minutes. Similarly, Li-Fi offers a much more secure network than Wi-Fi alone and LaaS is a trend that is fast being adopted by businesses globally.

“With growing urbanization the need for sustainable solutions is increasing. Energy efficiency and convenience will be driver of architectural and smart technical solutions including lighting on demand, activated through smart sensors as part of city lighting infrastructure.” Sudeshna Mukhopadhyay
