The current energy consumption of buildings occupies 23.5% of the total energy consumption in Korea, a high ratio, of which about 22% is consumed through lighting energy. For that reason, various experiments and research have been undertaken to reduce the energy consumption needs of indoor artificial lighting. This study suggests a light-shelf system applied with user recognized technology based on considerations of the light-shelf system and user recognized technology, and verified the possibility of introducing it to residences, and its effectiveness by comparing the results of energy reduction performance evaluations for the proposed light-shelf system with the user recognized technology and that with user unrecognized technology. The light-shelf system applying user recognized technology is a system that allows the occupant to set the luminance value of the room so that the light-shelf system and lighting can be interlocked and provide the luminance value requested by the occupant. In order to verify the energy reduction effects of the light-shelf system with the user recognized technology applied, this study has calculated the power consumption of lighting energy for a user unrecognized fixed light-shelf system, a user recognized fixed light-shelf system and a user recognized variable light-shelf system. From the results, when comparing the user unrecognized fixed light-shelf system and the user recognized fixed light-shelf system, Case A did not generate a reduction in energy consumption, and Case B saw a 4.4% reduction of lighting energy consumption levels. Case C generated a 13.3% reduction of lighting energy consumption. When comparing the user recognized fixed light-shelf system and the user recognized variable light-shelf system, power consumption was equivalent in Case A of one occupant and A, B and A, Case C for 2 occupants, while a 13.3% energy reduction was achieved for Case B of 1 occupant and B, Case C of 2 occupants. Case C of 1 occupant also achieved a 15.2% lighting energy consumption reduction. The user recognized variable light-shelf system showed the largest reduction of lighting energy power consumption, followed by the user recognized fixed light-shelf system and the user unrecognized light-shelf system in order of the reduction of lighting energy power consumption from user recognition.

Lighting in indoor space is being changed to system lighting converged with IT technology. Office space lighting with incandescent lamps and fluorescent lamps was completed through overall lighting plan by illumination in most cases, but convergence between LED lighting and IT technology enables the technology of responding to user requirements to be realized. Optical physical quantity suitable for humans and the lighting environment in accordance with user’s sensibility, based on space function and user’s behavior, would contribute to the improvement of service productivity, energy reduction, and enhancement of emotional satisfaction by providing user optimized lighting solution. Thus, user-customized system lighting guidelines to be applied with integration indicators of optics and sensibility are required. For the design elements required by users, environmental factors, product characteristics, optical characteristics, and sensibility factors are drawn from the design cases for office space and the survey, and the design check list and evaluation indicators are considered to reflect the requirements in the design and requirement indicators to give integrated satisfaction for optics and sensibility are developed. Purpose-centered design method from the user’s viewpoint is applied to function-focused design through scenario, and it should be applied flexibly, as the new lighting design method solutions, to the concept design stage of space lighting design and device development. This paper, therefore, presents user-customized guidelines by pursuing the optics and sensibility evaluation and design method combining the requirement conditions and scenario, to be used for lighting content development and design.

이정민,최경아,석현정 한국감성과학회 2013 감성과학 Vol.16 No.3

This user-centered research aims to empirically evaluate color temperature (K) and illuminance (lx) of residential bathroom lightings to determine the most optimal lighting conditions for productive task performance as well as for satisfying users’ emotional needs. Using 3 LED lighting fixtures, 4 types of lighting contexts were investigated; main lighting, task lighting, shower lighting, and bath lighting. Two lightings were installed parallel to the vertical edges of the main bathroom mirror to be used as main and task lighting, while another fixture was installed above the bathtub to be used for shower and bathing. For each lighting context, subjects (N=54) were instructed to perform a few tasks during which time the users were exposed to different lighting conditions with color temperature ranging from 2700 K ~ 6500 K and illuminance ranging from 100 lx ~ 700 lx. Upon completing the given tasks, subjects were asked to evaluate the lighting conditions and their applicability for performing the given tasks. Based on the user evaluations, the most optimal lighting conditions for the different lighting scenarios are as follow: 1) 3500 K ~ 4300 K and 150 lx for main lighting, 2) 3500 K ~ 4300 K and 500 lx ~ 700 lx for task lighting, and 3) 2700 K ~ 3500 K and 100 lx ~ 150 lx for shower/bath lighting. These results can be used to adjust the lighting standards suggested by KS, as well as be utilized by both engineers and designers in designing new types of user-centered bathroom lightings.

Studies for the reduction of lighting energy have been done using technologies such as user and location awareness. However, the focus of current research on location-based lighting control has been on energy reduction, which can lead to other issues including an imbalance in indoor illumination. This study proposes a lighting control system applying general illumination and technology for user and location awareness. The proposed lighting control system reduced lighting energy by 72.1%, 66.5% and 62.3% for 1, 2 and 3 users, respectively, compared to the On/Off lighting control system. This lighting control system causes an increase in lighting energy of 35.8% and 10.9% for 1 and 2 users compared to the lighting control system with user and location awareness, while a reduction of 9.4% was seen for 3 users. This means that the proposed system provides more effective energy reduction for a room with multiple occupants as it is based on the general lighting control scheme. The lighting control system applying general illumination and technology of user and location awareness improved the uniformity factor by 32.0%, 39.4% and 33.4% for 1, 2 and 3 users, respectively.

씽양,김종서 한국가구학회 2022 한국가구학회지 Vol.33 No.2

Entering the 21st century, the role of art museum design corresponds to changes in social structure, activation of various tourism and leisure industries, and changes in government policies. Art museums are moving closer to popular life. The function of the museum is in line with the exhibition, collection and aesthetic direction of many people. Based on this background, measures to enhance the users of art museums have become the focus of various countries, and become a representative measure to comprehensively evaluate the competitiveness of art galleries and museums. Art galleries are the main purpose of aesthetic appreciation for receiving silent messages of works of art. Therefore, it is more important to consider the visual communication of exhibition space and works than other cultural facilities. In addition, analyzing the correlation between viewing satisfaction of museum exhibition space and users’ viewing behavior is also an important consideration. The light of the space of the users of the modern art museum not only plays the role of lighting, but also expresses the space with light, which helps to improve the aesthetics of the audience who appreciate the exhibits. It does not exist simply by exhibiting works. It can also be used as a fixed track light source, or as a light source that the user can move at will, so that the designed light can better express the space. This study aims to recognize the necessity of light in art museum spaces and explore the relationship between light and space users in contemporary art museum spaces. To this end, it is planned to select representative art galleries after 2000 as the object of analysis, analyze the relationship between light and space users, reinterpret it from the perspective of various characteristics and expressions of light, and seek forward-looking development plans. The purpose of this study is to understand the design characteristics of leading art museums at home and abroad after 2000, and to draw lessons from future-oriented art museum designs based on the creative specificity and originality of each art museum. .

이수정,윤혜경 대한건축학회 2020 대한건축학회논문집 Vol.36 No.11

This study aims to propose the proper Unified Glare Rating (UGR) levels of light-emitting diodes (LED) lighting in office spaces. It wouldbe the basis data for the development of LED lighting for them. A literature review was investigated regarding the effects of backgroundluminance, luminance, solid angle, and position index on office users’ discomfort glare for fluorescent lighting and LED lighting in officespaces. The recommended UGR for the spaces is 19 or below and it was found that lighting that causes discomfort glare is located withinthe user’s field of view or in the line of sight. Discomfort glare within field of view was categorized as ceiling lighting and discomfortglare in the line of sight was categorized as wall lighting. In the case of ceiling lighting, discomfort glare of UGR≤19 resulted forfluorescent lighting with luminance of 4000 cd/㎡ and LED lighting with luminance of 2800 cd/㎡. For wall lighting, discomfort glare ofUGR≤19 resulted for fluorescent lighting with luminance of 2844 cd/㎡ and LED lighting with luminance of 1800 cd/㎡. The discomfortglares of office space ceiling and wall lightings were analyzed and found to be greater for LED lighting than for fluorescent lighting. Therefore, discomfort glare of UGR≤16 needs to be considered for LED lighting in office spaces. 이 연구는 업무공간에 사용되는 LED 조명을 위한 기본 자료로서 적합한 글레어지수 (Unified Glare Rating)를 제안하고자 한다. 문헌조사를 통해 업무공간에 사용되는 형광조명과 LED 조명의 사무직 근로자 불쾌글레어(discomfort glare)에 대한 배경휘도(background luminance)와 휘도(luminance), 입체각(solid angle), 위치지수(position index) 영향에 관해 조사하였다. 불쾌글레어 16 이하가 업무공간 LED 조명으로 제안된다.

In this paper, we studied the customized design for LED berth light of ship cabin based on the user’s behavior pattern analysis and lighting environment investigation. We studied the lighting design target, product design, design simulation, preparation of a prototype with a bidirectional radiation luminaire, and then measured and analyzed the lighting characteristics and lighting atmosphere. Upward lighting provides indirect illumination through the reflection to ceiling of the bed for the rest or sleep activities, whereas downward lighting provides enough illumination to the bed plane for the working or reading activities. In addition, illuminance and correlated color temperature (CCT) control was enabled by adopting warm and cool white LEDs with dimming. The prototype had the enhanced performance with α, δ, θ brain wave effect depending on the user’s behavior pattern and the improved berth lighting atmosphere was closely matched to user’s behavior patterns. The prototype was shown the better lighting performance with high flux, reduced glare and increased lighting efficiency compared to the conventional lighting fixtures.
