“…It is evident that the use of parallel optimization algorithms [43] plays a key role in the optimal design of the lighting system that requires investment and operating costs minimization, as well as uniform light distribution over the plant growing area, accounting for light intensity capability and shading effects [44,45]. In outdoor applications, accurate methods have been developed to test the road lighting effects to ensure a good visibility in the street [46][47][48][49][50].…”

Energy-saving lamps are equipped with converters enabling high energy efficiency at the cost of injecting very distorted currents on the mains. The problem is more complex in the emerging smart-lighting scenario where these lamps are also used to perform additional tasks. Harmonics mitigation at the lamp level is expensive; consequently, an optimal lighting system design aiming at reducing both costs and current distortion of the whole lighting system is necessary. A tool able to emulate the current drawn from the lamps is necessary for optimal design. Such a tool has also to consider the fluctuations of the voltage on the mains that usually occur throughout the day. In this perspective, a parametric PSpice circuit is proposed and the netlist is reported in this work. Moreover, the simple procedure to be adopted for computing the parameters is also described. The validation has confirmed the ability of the proposed circuit in emulating the current drawn from various CFLs and LED lamps under different supplying voltage.

“…The measures are obtained according to the IES LM-79-08, the EN 13032-1:2004, the EN 5489:2012, and the ILP PLG-03 (2012) standards. The tests used the C-range assessed for public lighting luminaires [31,32]. This method ensures the whole visual field around the lighting source is analyzed and evaluates the comfort and discomfort of a lighting environment based on the glare sensation [33].…”

Evaluation of Uniformity and Glare Improvement with Low Energy Efficiency Losses in Street Lighting LED Luminaires Using Laser-Sintered Polyamide-Based Diffuse Covers

Energy saving in street lighting is garnering more interest and has become a priority in municipal management. Therefore, LED luminaires are gradually becoming prevalent in our cities. Beyond their energy/economic saving potential, quality in public lighting installations concerns aspects such as uniformity and glare which must be maintained if not improved in any installation renewal project using this technology. The high light intensity generated in a discrete point in LED packages and its directional nature result in significant deficiencies in these last two parameters. To soften these effects, translucent covers are being used as one of the most common solutions with the drawback of significant light intensity losses. The objective of this paper is to evaluate the behavior of LED luminaire's polyamide-based optical covers manufactured with a laser-sintered process. These are designed to improve glare and uniformity output, to minimize light output reductions, and to be industrially manufactured with no increment of cost for their lighting equipment compared to conventional transparent polycarbonate solutions. A laboratory and field lighting test study has been applied to different covers with the same LED lamp and luminaire to compare the performance of three different solutions built with different polymeric materials and with different light transmission surface textures. The photometric results have been observed and discussed to demonstrate the ability to significantly improve the lighting performance of LED luminaires-illuminance and uniformity levels and discomfort and disability glare indexes-using an improved optic cover.

“…Considering new lamps and technologies as LEDs [6] or metal halide lamps [7], different methods and methodologies for street lighting design have been proposed. The road lighting calculations doubled by measurements proved that, depending on the calculation method, the same road lighting installation may result in different road-lighting quality-parameter values.…”

The design of the outdoor lighting is based on the point-by-point method to estimate the direct component of the illuminance and it has a high complexity. This complexity is higher as the spatial repartition of the luminous intensities is more asymmetrical and as the more random is the position between the luminaire and the visual task. At the present, the lighting-domain specific software helps for quick and precise calculus, using some complex formulas with different degrees of generality. The present paper proposes a new way in applying the point-by-point method, by a different estimation of the zenith ( ) and azimuth ( ) angles. It uses an orthogonal reference system placed in an arbitrary point, which is transformed by successive rotations into a more convenient one. Using this new method, the resulted relations have a higher generality and the calculus time is shorter, especially in the very complex systems. Even seem apparent complicated, the obtained formulas are a result of the calculus with rotation matrices and can be easy implemented into the software. Moreover, they can be easily customized for any specific conditions.
