Introduction
Today, excessive energy consumption is emerging as a global issue. Various plans are
being discussed to reduce energy consumption of buildings that take up 38% of total
energy consumption. Among them, Smart Lighting Control System using IT such as
location-aware technology is receiving attention as a new area of study in reducing
indoor lighting energy. For efficient lighting control of indoor space, various contexts
must be considered in applying to the integrated system. Therefore, this study aims to
come up with plans to improve the energy reduction performance of the basic model
of Smart Lighting Control System that applied user-aware technology, and prove its
validity through performance evaluation.

Consideration of Smart Lighting Control System
Purpose of Smart Lighting Control System
Smart Lighting Control System applies an intelligent system through convergence
with IT, breaking away from the lighting control method. Smart Lighting Control
System has the following two purposes. First is the lighting energy reduction effect.
Activity space of humans requires appropriate illumination. The source of sunlight
flowing indoors has a limited securement of illumination, and thus artificial lighting is
used, which consumes energy in management. To reduce energy consumption, a
paradigm shift in the control system is required, and the intelligent system accedes to
that demand. Second is providing a pleasant light environment. The main
environment in a space is created by light, temperature, humidity and noise, among
which the light environment is a positively necessary factor for visual activities.
Today, there are many studies on secondary elements such as the quality of behavior
or atmosphere more than necessary. Smart Lighting Control System provides a
pleasant light environment to meet such demands on a real-time basis, improving the
quality of the use of space.
2.2
Implementation of Smart Lighting Control System
I suggest the application of location awareness technology to supplement the
limitations of sensor-based dimming systems. If location awareness technology is
utilized, as the location information of the user in a space is analyzed in real time and
connected to an intelligent response, higher energy savings compared to sensor-based
dimming systems can be realized. Additionally, as it is possible to reasonably respond
to various situations, it can achieve high satisfaction of users in terms of the quality of
the light environment.
The key to Smart Lighting Control System is in intelligent integrated system. The
differentiation factors of intellectualization are automation in which it is not
controlled directly by people, ability to judge the situation real-time, and performance
that maintains the optimum space environment. The intelligent system began from the
intelligent building system (IBS) and has since continued to evolve in order to
improve performance along with the advanced IT.
The key mechanism of Smart Lighting Control System includes collection of
spatial data, judgment by control algorithm, and correspondence to maintain the
optimum environment. In the spatial data collection process, various sensor
technologies that meet the required conditions are used. Data collected from this
process are analyzed by the algorithm of the control logic of Smart Lighting Control
System, producing the optimum value. The ultimately produced value is printed as the
physical performance of the lighting control, resulting in effective lighting energy
consumption and providing the optimum light environment.

Ways to Improve Performance of Smart Lighting Control System
To improve performance of Smart Lighting Control System, it is necessary to analyze
factors that influence performance and establish an integrated system to determine
and collect types of valid data. Users using the space have various lighting
requirements. However, the general lighting control method that has been implement
thus far had limitations in that it could not meet such diverse lighting requirements.
The simple ON/OFF lighting control method provides a uniform illumination, thereby
failing to increase the qualitative level of the light environment and also causing the
issue of wasting unnecessary lighting energy. Therefore, this study aims to propose a
basic model of Smart Lighting Control System based on user awareness, and verify its
energy saving performance through an experiment on the test bed.

User Awareness Technology-based Smart Lighting Control
System Basic Model
3.1
User Awareness Technology
Users have various demands for amenity of the environment according to the spatial
characteristics as well as their taste. The demands of users are classified into various
types by purpose of use, age level and taste. However, the environment control
method thus far has focused on satisfying the basic recommended average and
thereby has qualitative limitations in the spatial environment. As User Awareness
Technology actively responds to the diverse needs of users, it is possible to establish
an effective control system, save energy, and improve the quality of the spatial
environment.
3.2
Proposal of User Awareness Technology-based Smart Lighting Control
System Basic Model
Different lighting requirements of users are set up on User Awareness Technology.
The user awareness within the space is received via the tag possessed by the user. The
lighting requirement set up through the recognized user information is provided
within the space. Here, if illumination flowing indoors from the outside is measured
and applied to the lighting control system, energy can be saved more effectively.

Conclusion
By using various IT in lighting control, Smart Lighting Control System can
effectively save energy and qualitatively improve the indoor light environment. This
study proposed the User Awareness Technology-based Smart Lighting Control

research to find more effective ways to save energy. More research on Smart Lighting
Control System is necessary in order to further improve performance.
