Technology Evolution and Power Quality Issues in Designing Future Lighting Systems

Dear Colleagues,

Smart lighting is a technology moving towards energy efficiency with additional functionalities intended to improve the quality of life in private houses, offices, and industrial locations. Smart street lighting additionally exploits innovative technologies able to increase roadway safety while reducing maintenance costs. Farming technologies are used for indoor growing of plants without sunlight; they present the further advantages of controlling plants growth and avoiding the use of pesticides.

Several other technologies are already widespread or emerging in the field of lighting system. In view of fully integrated and interconnected technologies and systems, more and more technologies will be required in the future because the lighting system is an important element of smart buildings and smart cities.

The energy-saving lamps adopted in the new lighting system scenario have converters that enable them to reach high energy efficiency levels at the cost of injecting high distorted currents in the mains. The problem is exacerbated in the complex scenarios described above where these lamps are also used to perform additional tasks.   

This Special Issue will focus on emerging power electronics technologies for harmonics limitations in smart lighting. In the perspective of an optimal lighting system design, methods and solutions able to reduce the distorted current at the lighting system level rather than at the lamp level are especially welcomed.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
