Energy Efficiency Considerations for LED-Based Lighting of Multipurpose Outdoor Environments

Abstract

Nowadays street lighting accounts for 53% of outdoor lighting use and the market is continuously increasing. In the context of rising energy prices and growing environmental awareness, energy efficiency is becoming one of the most important criteria for street lighting systems design. LED-based lights have become the primary option for replacing conventional light bulbs, being digitally controllable, small, highly efficient, and cheap to manufacture. Advanced control strategies adapted to ambient conditions are needed to combine low energy consumption and high quality light ambience according to changing specifications. This paper describes an outdoor lighting solution aimed at energy efficient performance in the context of multipurpose outdoor environments, where control is crucial in achieving efficiency improvements. The work addresses efficiency at the component level, by optimizing the performance of LED drivers, and at system level, defining the control strategy and associated hardware infrastructure. The approach designed was tested in a real environment. The performance of the lighting installation was assessed using the web-based monitoring application, providing real-time consumption information and aggregated historical data.

Revision of Smart Street Lighting LED

“…The LED luminaire has important features for smart lighting, such as greater efficiency in lumens per Watt [Lm/W], a long lifespan (between 5 to 8 years), the ability for switching multiple times [ON-OFF] without damaging its lifespan, low attenuation of light intensity and good color reproduction. [31], [32]. High Intensity Discharge (HID) solutions [35].…”

“…High Intensity Discharge (HID) solutions [35]. In Table 1, the characteristics between different types of luminaires can be compared: luminarias are pertinent for this type of lighting [32], [36]. Something similar happens with the HID luminaire.…”

Towards the Adoption of Cyber-Physical Systems of Systems Paradigm in Smart Manufacturing Environments

“…More precisely, these controllers are the Inico S1000 Industrial controllers 5 , which are connected to a hub, marked as (B), for its configuration throughout the same network. Previous research demonstrates how to use such controllers considering energy-efficiency for LED-based lighting of multipurpose outdoor environments [55]. Moreover, the industrial controllers are connected through Wi-Fi to Temperature, Humidity and Light (THL) sensors which are strategically placed around all the facility for monitoring such type of measurements.…”

Development of LED Light Sources in Landscape Lighting

“…These trends cause the lighting industry to undergo a major transformation. The rapid development of LEDs has made this revolution possible not only because the energy-saving characteristic of LED lighting meets the requirements of the form; moreover, the dynamic changes not only further suit the needs of the market but also able to render the lights under night conditions [1]. Garden landscapes are ideal paradise and motivation for people.…”
