“…In this study, several of the most relevant photometric properties of recent LED lamps for public lighting have been analyzed, with a particular emphasis on aspects related to the perception of quality by road users: illuminance levels, uniformity, and disability and discomfort glares [35]. For this type of installations, special care must be taken when considering all these parameters, due to the discomfort generated by the directional effect of their light output and the reflections produced in the cover of the enclosure of luminaires that protect the discrete electronic emitters.…”

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.

One's cognitive perception of the environs is in direct relationship with their subjective mental image of the surroundings. Various elements influence the perception and legibility of the environment before human mind. Among these elements are the light and color of the environs. The question is which light or color spectrum is capable of heightening the legibility and spatial perception of the given environment for users. Considering that, the aim of the present study is first to examine the effect of lights and colors on the legibility rate of interior spaces, and then, to identify the reasons users have chosen them. To this end, authors have used augmented reality technology to simulate a variety of environments based on different light and color parameters. A group of 120 students from the Faculty of Art and Architecture of Islamic Azad University, West Tehran Branch, collaborated with the authors to carry out the study. For the purpose of the experiment, the interior of the faculty building was simulated using 3D software and was put through experience and evaluation by using augmented reality technology. Eventually, the students were asked to select those environments they deemed as featuring more perception and legibility than others. The participants' spatial perception was tested by assigning the type of the environment as the dependent variable. Color, light, and gender were examined as the independent variables. Chi-square test was used to determine the difference between the frequencies of the environments selected by the participants. Results showed that neutral color was more attractive than the other two color spaces. There was no significant difference between three color spaces in terms of guidance and invitation. Generally, the participants preferred neutral color over the other two colors. In other words, neutral color was better perceived than the other two because of its greater attractiveness.

“…The design of an artificial lighting environment is a challenging task that involves the satisfaction of several physical and psychological criteria [23][24][25]. For example, an adequate level of illuminance over the working plane needs to be provided while maintaining the uniformity of illumination; bright patches need to be avoided to eliminate or reduce glare and visual discomfort; etc.…”
