This paper describes an innovative Energy Consumption Management System (ECMS) that is aimed at rationalizing the end use of the electrical energy in tunnel lighting. It is based on agent technologies and Power Line Communications to achieve lowest consumption lighting conditions in an optimal way. Depending on the type of application, the system would lead also to reduced installation and runn...

Light-emitting diodes (LEDs) are promising lighting sources for general lighting applications with the promise of being more than ten times as efficient as incandescent lighting. Such characteristic combined with their long operating life and reliability has made them becoming a potential choice for next generation of lighting systems including automotive, emergency, backlight, indoor, and outd...

The Internet of Things (IoT) is opening up new services and is stimulating changes in industries. The lighting industry is also embracing this change by establishing an Internet of Lights (IoL). This article highlights the main benefits and the challenges to face while going towards IoL. To address these challenges and cater to the specific requirements of lighting networks, an IoL reference ar...

The adoption of energy efficiency measures in building codes places constraints on lighting designers that they fear will reduce the quality of the lit environment. This experiment was designed to test the hypothesis that lighting quality, as understood by lighting designers, affects the task performance, mood, comfort, health, and aesthetic judgements of office workers. Nine lighting systems w...

Lighting systems provide mine workers improved visibility and contribute to improved safety, productivity, and morale. Lighting is critical to miners, since they depend heavily on visual cues to spot fall of ground, pinning & striking and slipping & tripping hazards. Most conventional systems of lighting are used in mines are extracting a lots of power and deal with major maintenance problems. ...

Power quality in public lighting networks is yet not sufficiently studied today. New conditions and requirements arise as a consequence of rapid application of new technologies like LED lighting, lighting control and monitoring, adaptive lighting systems etc. Optimization of reliable and efficient service of public lighting systems can be only achieved if behaviour of individual elements within...

variations in lighting are a problem for visual systems. in the current research, a new thresholding method using a 3d euclidian elliptical surface was defined and applied for plant detection purposes. the results showed that this method had lower type i error, type ii error, total error and mean square error compared with those of conventional segmentation methods. the method was evaluated for...

operations. Underground mines are completely dependent measuring of illuminance and [2 & 3]. If they are carefully designed and implemented, lighting systems provide mine workers improved visibility and contribute to improved safety and productivity. Effectively designed lighting systems can prove to be a very cost investment in underground mines. Instruments are required to evaluate lighting s...
