LED Context Lighting System in Residential Areas

Abstract

As issues of environment and energy draw keen interest around the globe due to such problems as global warming and the energy crisis, LED with high optical efficiency is brought to the fore as the next generation lighting. In addition, as the national income level gets higher and life expectancy is extended, interest in the enhancement of life quality is increasing. Accordingly, the trend of lightings is changing from mere adjustment of light intensity to system lighting in order to enhance the quality of one's life as well as reduce energy consumption. Thus, this study aims to design LED context lighting system that automatically recognizes the location and acts of a user in residential areas and creates an appropriate lighting environment. The proposed system designed in this study includes three types of processing: first, the creation of a lighting environment index suitable for the user's surroundings and lighting control scenarios and second, it measures and analyzes the optical characteristics that change depending on the dimming control of lighting and applies them to the index. Lastly, it adopts PIR, piezoelectric, and power sensor to grasp the location and acts of the user and create a lighting environment suitable for the current context.

Smart Lighting Application for Energy Saving and User Well-Being in the Residential Environment

“…Other definitions for smart lighting systems were 'automated', 'innovative', 'multi-objective', 'biodynamic', and 'context' lighting. It seems that the terms 'intelligent' and 'multi-objective' represent a kind of lighting system that, in addition to energy saving, can offer more services to the users, such as the adjustment of the lighting based on recognition of user activities [38][39][40][41][42].…”

Development and Implementation of a Self-Optimizable Smart Lighting System Based on Learning Context in Classroom

“…Evidence indicated that a well-designed mobile application can not only improve user experience, but also guarantee the compliance of illumination regulations and reduce energy consumption [36]. In other studies, both illuminance and CCT were considered for improving users' visual comfort and wellbeing by adapting lighting environment to users' activity [26,32].…”

Lighting Control System Based on the RTP of Smart Grid in WSN

“…Table 5 shows the illumination level of office buildings in the country and that recommended by the IESNA, USA. In the KS A 3011, the ranges of illuminances (lx) are specified as minimum, medium, and maximum illuminance according to activity types, while the illuminance standard recommended by IESNA is specified as to choose a single value by considering the condition and characteristics of space, age of user, and speed and accuracy level of work [33].…”
