Massive Development

Constant development of LED light sources (LS) and lighting control systems establish a potential for development of brand new lighting installations (LI) which allow us to increase efficiency of human performance for both short periods of time and for the entire active period of life. For massive development of such LIs, it is necessary to have a methodology for evaluating their efficiency. Such methodology has been developed and tested and has prospects of development requiring constant collection and consideration of new information. In view of this, the article describes experimental evaluations of parameters of visual functions and psycho-emotional and physiological states of spectators in static and dynamic lighting by LED LSs.

Learned Features

High-quality lighting positively influences visual performance in humans. The experienced visual performance can be measured using desktop luminance and hence several lighting control systems have been developed for its quantification. However, the measurement devices that are used to monitor the desktop luminance in existing lighting control systems are obtrusive to the users. As an alternative, ceiling-based luminance projection sensors are being used recently as these are unobtrusive and can capture the direct task area of a user. The positioning of these devices on the ceiling requires to estimate the desktop luminance in the user's vertical visual field, solely using ceiling-based measurements, to better predict the experienced visual performance of the user. For this purpose, we present LUMNET, an approach for estimating desktop luminance with deep models through utilizing supervised and self-supervised learning. Our model learns visual representations from ceiling-based images, which are collected in indoor spaces within the physical vicinity of the user to predict average desktop luminance as experienced in a real-life setting. We also propose a self-supervised contrastive method for pre-training LUMNET with unlabeled data and we demonstrate that the learned features are transferable onto a small labeled dataset which minimizes the requirement of costly data annotations. Likewise, we perform experiments on domain-specific datasets and show that our approach significantly improves over the baseline results from prior methods in estimating luminance, particularly in the low-data regime. LUMNET is an important step towards learning-based technique for luminance estimation and can be used for adaptive lighting control directly on-device thanks to its minimal computational footprint with an added benefit of preserving user's privacy.

<p>Currently, energy saving requires the development of simple and efficient street lighting control systems. In order to create such a control system, it is necessary to develop an original principle of its operation. They considered the advantages of electronic starting devices in street lighting control systems. They performed the analysis of the existing state of street lighting means, their shortcomings and solutions have been determined, and they developed the method of lighting device automatic control. They performed the assessment of the economic effect from loss reduction associated with reactive power and due to power reduction during deep night. They presented the example of economic effect achievement from the use of an electronic starting device with automatic power reduction.</p>

New Framework

<p>'Tangible lighting controls' is used as an umbrella term to describe lighting control systems that are easy to understand and pleasurable to use by end-users. The crucial question posed is, what is the nature of interface designs sought by end-users for maximising interaction with lighting control systems? The manner in which this question is posed implies a fundamental assumption that improved usability and end-user experience are the primary goals. The concept of end-user understanding of lighting control interfaces is proposed as a basis for improving the usability and end-user experience of lighting control interfaces. Usability engineering methods involving survey research, experimental mock-ups and prototyping have been used to enable end-users to design and evaluate lighting control interfaces. The essential difference is to include end-users' point of view about ease of understanding control functions and pleasure of performing control tasks along with a technical point of view about meeting required standards. Manufacturers' claims about the effectiveness of existing lighting control interfaces are challenged, and an entirely different way of thinking about interface design is revealed. Such a change of thinking may be seen as a new framework for improved designs of lighting control interfaces as well as evaluation of their usability and end-user experience.</p>
