“…Furthermore, Sedziwy et al [5] allows obtaining power saving not only by replacing high pressure lamps with LEDs, but also by improving a design quality and by introducing a dynamic street lighting control. In addition to the paper [6] the authors improved the energy efficiency and quality of street lighting by applying two different solutions to achieve energy saving in street lighting design: the installation of luminous flux regulators and the replacement of existing luminaires with LED.…”

The installation of smart meters in smart cities to monitor streetlights (SLs) provides easy access to measurements of electrical variables and lighting levels, which improves the operation of installation. The use of smart meters in cities requires temporary high-resolution data to improve the energy efficiency (EE) of SLs. Long range (LoRa) is an ideal wireless protocol for use in smart cities due to its low energy consumption, secure communications, and long range indoors and outdoors. For this purpose, we developed a low-cost new system and successfully evaluated it by developing three devices, namely the measure and control device for street lights (MCDSL), lighting level measurement device (LLMD) and gateway LoRa network (GWLN), based on the Arduino open-source electronic platform. This paper describes the hardware and software design and its implementation. Further, an algorithm has been developed to enhance the energy efficiency of public lights using MCDSL, the energy efficiency for street lights (EESL) algorithm, that use the illumination level measured on the same set of SLs with a dynamic control, which assumed different lighting levels throughout the night, and adjusted luminous flux based on the traffic intensity of pedestrians. It sends the acquired data through the LoRa low-power wide-area-network (LPWAN) to the cloud.

“…Moreover, all these outdoors luminaires have a high impact on the citizens' perception of safety and quality of life [2]. The annual electric energy costs related to street lighting are estimated to reach between $23.9 billion and $42.5 billion by 2025 [3]. In addition, each streetlight point is responsible for generating between 330 and 1500 kg of CO 2 each year according to a 2014 report by market researchers at the Northeast Group [4].…”

Nowadays, control systems for lighting installations are used, among other functionality, to improve energy efficiency and to set different lighting outputs of the luminaires according to punctual requirements. This allows increasing energy efficiency by adapting the installation to environmental needs. Current control systems are mainly oriented to point-2-point architectures, which in most cases, are complex and expensive. As an alternative, we present the viability analysis of a sustainable control architecture for lighting installations to improve those drawbacks. This control system uses a communication technique based on controlled power-on/off sequences in the power line of the luminaires to configure different dimming profile schedules. An implementation for LED equipment with the design of an electronic CPU based on a microcontroller is described along with a study of its configuration capability. In addition, we present the set of results obtained using this system in a real outdoor public lighting installation. Furthermore, an economic amortization study of power line communication (PLC) or radio frequency (RF) control architectures versus the results of this proposal are detailed. The analysis presents the proposal as a simple but more robust and sustainable solution compared to current point-2-point systems used with streetlights: The return on investment (ROI) period is reduced allowing all the basic functionality expected—in—field output light dimming profiles selection.

“…Due to their superior properties, light emitting diodes (LEDs) are more often replacing traditional lighting systems, for example in household lighting, electronics and street lamps. 1,2 In addition, LED lamps used for lighting in plant production in greenhouses and indoor growing systems challenges conventional lamp types. The properties of LEDs are described in the next paragraphs in more detail.…”

“…As an example, in terms of heat emissions, LED has the lowest emissions (ranked as 5) and HPS has the highest (ranked as 0). Luminous efficiency data of CFL is ranked and normalised based on Eqn (2), and hence the result is 3.4. The normalised ranking results are presented in Table 2.…”

Based on available literature, ecology and economy of light emitting diode (LED) lights in plant foods production were assessed and compared to high pressure sodium (HPS) and compact fluorescent light (CFL) lamps. The assessment summarises that LEDs are superior compared to other lamp types. LEDs are ideal in luminous efficiency, life span and electricity usage. Mercury, carbon dioxide and heat emissions are also lowest in comparison to HPS and CFL lamps. This indicates that LEDs are indeed economic and eco-friendly lighting devices. The present review indicates also that LEDs have many practical benefits compared to other lamp types. In addition, they are applicable in many purposes in plant foods production. The main focus of the review is the targeted use of LEDs in order to enrich phytochemicals in plants. This is an expedient to massive improvement in production efficiency, since it diminishes the number of plants per phytochemical unit. Consequently, any other production costs (e.g. growing space, water, nutrient and transport) may be reduced markedly. Finally, 24 research articles published between 2013 and 2017 were reviewed for targeted use of LEDs in the specific, i.e. blue range (400-500 nm) of spectrum. The articles indicate that blue light is efficient in enhancing the accumulation of health beneficial phytochemicals in various species. The finding is important for global food production. © 2017 Society of Chemical Industry.
