Smart lighting systems: state-of-the-art and potential applications in warehouse order picking

Abstract

Artificial lighting is a constant companion in everyday private and working life, influencing visibility in interior spaces as well as outdoors. In recent years, new technical solutions have extended traditional lighting systems to become 'smart'. Different types of smart lighting systems are available on the market today, and researchers have concentrated on analysing their usability and efficiency, especially for private households, office buildings and public streets. This paper presents a systematic literature review to analyse the state-of-knowledge of technologies and applications for smart lighting systems. The results of the review show that smart lighting systems have been frequently discussed in the literature, but that their potentials in industrial environments, such as production and logistics, has rarely been addressed in the literature so far. Lighting systems for industrial environments often have very different requirements depending on the working environment and operating conditions. Based on the results of the literature review, this paper contributes to closing this research gap by discussing the usage potential of smart lighting systems to improve the efficiency of warehouse order picking, which is an application that may benefit from various functions smart lighting systems provide. Several propositions are developed that emphasise research opportunities and managerial implications in this context.

ICT Driven Smart Lighting Solution “iLIGHT” for Smart Cities: A Conceptual Framework

“…Authors have also clarified that replacing traditional lights with LED Lights and with the dimming of light intensity using their lighting system deployed in the city of Luxembourg, realized the huge savings in energy cost in the first year of deployment itself. Marc Füchtenhans, Eric Grosse & Christoph Glock in their paper "Smart lighting systems: state-of-theart and potential applications in warehouse order picking" carried out a detailed literature review to analyse various technologies used and applications of Smart Lighting Systems [7]. The authors specifically stressed the applications of SLS in industrial environments including production and logistics and clarified that SLS in industrial environments has to fulfil some specific requirements based on working environments and operating conditions.…”

Role of Architectural Design in Creating Circadian-Effective Interior Settings

“…Besides the visual and non-visual benefits, daylight use in the built environment is important to decrease the energy consumption caused by electric lighting [33]. When daylight is not present or sufficient, electric lighting systems are used to satisfy lighting requirements [33,34]. The energy efficiency of these artificial systems is significantly determined by occupants' behaviors.…”

“…Sensor-based lighting has been used for a very long time as a central control system. The sensors detect occupancy, motion, or other external factors and adjust lighting levels based on these factors [33,34]. Daylight sensors are placed in spaces where natural light can satisfy full or partial lighting requirements.…”

“…Energy savings can be even more if daylight sensors are combined with motion sensors [39]. In addition to reducing energy consumption, sensor-based lighting systems can adjust the lighting intensity and color temperature to match the user's preference, and thus, can positively affect the user's circadian rhythm and increase productivity [34].…”

“…A lighting control system is considered a smart lighting system (SLS) if it uses advanced building technology and an internet-based network to convey data [33]. LEDs are the most efficient artificial light sources today, and they form the foundation of many emerging technologies and current lighting systems, including SLSs [33,34]. LEDs have the ability to change light intensity and color temperature, but they need to be combined with control systems and sensors to form SLSs.…”
