Indoor of 21th century information-oriented society is feeling necessity of emotional design that can satisfy emotional of human. Desire of modern becomes various and emotional lighting design is risen on important element in indoor plan on human oriented modern society who become complicated. Emotional space is trend that is atomized as go today and is expanded as the target and area also go. That is, is included as target of emotional space to light and sound, taste, smack and is appealing by senses of human. Wish to do color that is optical element among element of senses differently and present design. Design concept of this research is emotional lighting design that can receive. It is lighting that equip emotional beauty and ability from modern indoor improving space. I wish to quote emotional lighting design about effect gotten to indoor by sight of designer.

본 연구에서는 대구시 동대구로의 경관조명에 관한 주민의식을 조사하기 위하여, 대구시에 거주하는 20대 대학생 500명을 대상으로 설문조사를 하였다. 그 결과, 야간경관에 가장 큰 영향을 미치는 요인은 조명이 69.2[%]로 가장 높았으며, 대구의 도시이미지는 교육과 문화가 가장 높게 나타났다. 대구시의 경관디자인 시 중점을 두어야 할 것은 '자연과 어울리게'가 높게 나타났다. 야간경관에서 가장 큰 영향을 미치며 동시에 가장 열악한 것은 '조명'이며, 현재 조명상태나 밝기는 부정적으로 나타났다.

The compressed injection yellow ocher soil is the process-technology by drying the product through sunshine, not by firing like pottery and ceramic ware. It is the technology of development being able to achieve the far infrared ray and humidity adjustment by adding recycling paper, Korean paper and bamboo salt, and it corresponds with the construction enforcement ordinance 2007 as an interior-finishing product which is fire-resistant. In case that the yellow ocher soil would be used as lighting device and interior-finishing material and decoration, it could contribute to an improvement of National Health by avoiding the sick house syndrome and adding humidity adjustment, and it has more efficient economic effect due to using recycle-available additives. Through such developments of the yellow ocher soil products the domestic market of lighting device and construction material can be advanced and the replacement effect of imported goods & also export effect can be expected accordingly.

국제 조명시장의 성장과 국내 경관조명시장의 확대로 인해 최근 조명시장은 활성화되어 가고 있다. 그러나 이러한 변화에 비해 국내 조명기술과 조명기구디자인개발기술은 국제 경쟁력을 갖추지 못한 체, 가격만을 경쟁하고 있다. 특히 국가 및 지자체의 정체성 수립에 많은 관심이 집중되고 있는 현 시점에서 지역 및 국가의 이미지는 도시의 경관에 의해 크게 좌우될 수 있기에 많은 도시들이 이에 힘을 쓰고 있다. 한 도시의 경관은 자연생태환경을 포함한 다양한 구조물들이 모여 이미지화 되어지고, 이는 곧 그 안에 살고 있는 사람들의 의식과 문화를 대변하는 것이다. 도시의 주경에 비해 야경은 자연채광을 기본으로 생활조명과 더불어 경관조명에 의해 보다 가시화되어질 수 있다. 도시의 야경이 우수해진다는 것은 단순히 도시의 미관이 미려해지는 것 이상의 의미, 곧 도시 효율과 삶의 질이 고양됨을 의미한다. 이에 PLS 조명기술개발과 300W급 조명기구디자인개발을 통해 효과적인 조명기술 및 신제품디자인 프로세스 확립하고, 나아가 국내 경관조명시장의 국산화 및 국내 조명시장의 경쟁력을 제고하고자 한다.

The furniture of the Joseon era, life sense of human forms a culture has appeared well. Feeling of life refers to the sense of feel natural to the history and traditional culture of the area and their own customs. Further, it is possible to be a sense that reflects the mental contents ego, ethical and religious. Furniture traditional and sophisticated sense like this is to take care of the sophistication that comes out from the inside than the beauty artificial as a function of the sense and user preferences. This is a feeling of unique Korean. Due to changes in the housing, the beauty of these illustrates the altered form mechanically a uniform in modern times. Have that desired to be manufactured furniture by applying the neck Korean furniture of our living environment that will change in Western Europe of today, with the tradition of the modern lifestyle.

Motivated by the need for developing the more efficient lighting system for light culture in the greenhouses, this paper aims to predict the illumination of incandescent lamp according to various levels of lighting and various kinds of the lamp. The results obtained in this experiment are summarized as follows. 1. The general equation to predict the illumination according to the kind of incandescent lamp and the installation height was suggested as {{{{y= { a + bx+ cx^2} over { 1+dx+ex^2~ + fx^3} [lx]}}}} , where , a, b, c , d, e and of were arbitrary constants. 2. Maximum illumination of hat-covered lamp of 60 W was 1.2 -1.5 times as many as uncovered lamp. 3. Maximum illumination of yellow color painted lamp of 100 W was 1.3 times as many as unpainted lamp.

Harvested de-astringent persimmon 'Fuyu' were treated with various lighting sources under low (3℃) and high (22℃) temperatures. The weight loss rate of fruits was lower in those with Red LED than Fluorescence and Blue LED under both temperature conditions. Hardness and soluble solid content of fruits were higher in those with 3℃ / Blue LED or mixed LED (Blue+Red LEDs). Beta-carotene and lycopene content of fruit peel were higher in those with 3℃ than 22℃ and with Red LED or light sources with mixed red wavelength under both temperatures. When the fruits treated with light and temperature were stored for 4 days under 3℃ / dark condition, the hardness of the fruits did not significant difference among the treatments. Taken together all the results, it would be best to treat it light sources mixed red wavelength under 3℃.

동계 절화장미 'Vital'재배시 보광이 장미의 생육과 절화수량에 미치는 영향을 구명코자 하였다. 보광 광원은 250W의 메탈할라이드등, 고압나트륨등 및 혼합(메탈할라이드등+고압나트륨등)등을 베드 위 120cm 높이에 $310cm{\times}450cm$로 설치하였다. 보광등에서 1m 떨어진 지점의 광도는 $32{\sim}34{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$였다. 보광구는 무처리구에 비해 개화소요일수가 1번화는 $5{\sim}8$일, 2번화는 $3{\sim}5$일 단축되었다. 보광구 간에는 혼합등이 개화소요일수가 가장 짧았고, 고압나트륨등, 메탈할라이드등 순 이었으나 차이가 크지 않았다. 생육도 보광구가 무처리구에 비해 좋았다 특히 블라인드 발생이 $5{\sim}7%$ 감소되어 절화수량 증가의 주 요인이었다. 보광구간에는 혼합등이 가장 좋았고, 메탈할라이드등, 고압나트륨등 순 이었으나 큰 차이는 없었다 결론적으로, 보상점보다 낮은 광도의 보광도 개화소요일수 단축 및 블라인드 발생억제에 효과적이었다.

BACKGROUND: Light-emitting diodes (LEDs) with lower electric cost and the specific wavelength have been considering as a novel light source for plant production in greenhouse conditions as well as in a closed culture system. Supplementary lighting for day-length extension was considered as light intensity, light quality, and/or photoperiod control on plant growth and development. Effects of supplementary blue or red LED radiation with lower light intensity on growth of Ageratum (Ageratum houstonianum Mill., cv. Blue Field), African marigold (Tagetes erecta L., cv. Orange Boy), and Salvia (Salvia splendens F. Sello ex Ruem & Schult., cv. Red Vista) were discussed during sunrise and sunset twilight in the experiment. METHODS AND RESULTS: Supplementary lighting by blue and red LEDs for 30 (Treatment B30; R30) or 60 (Treatment B60; R60) min. per day were established in greenhouse conditions. Photosynthetic photon flux for supplementary radiation was kept at $15{\mu}mol\;m^{-2}\;s^{-1}$ on the culture bed. Natural condition without supplementary light was considered as a control. The highest shoot and root dry weights were shown in African marigold exposed by red light for 60 min. per day. Supplementary blue and red lighting regardless of the radiation time significantly stimulated development of lateral branches in African marigold. Stem growth in Ageratum and Salvia seedlings was significantly promoted by red radiation as well as natural light. CONCLUSIONS: Extending of the radiation time at sunrise and sunset twilight using LEDs stimulated reproductive growth of flowering plant species. Different characteristics on growth under supplementary blue or red lighting conditions were also observed in the seedlings during supplementary radiation.

This study examines influences of a daylight dimming control system on the variation of indoor illuminance and lighting energy savings in a small office space. Field measurements and a series of computation were performed for typical types of sky conditions in summer. Results indicate that the daylight illuminance under clear and partly-cloudy sky were close to the target illuminance during a majority of time due to a higher ratio of window to wall. However, the target illuminance was not kept successfully due to the variation of photosensor signals which were strongly influenced by desktop illuminance. The system with partially-shielded conditions succeeded to keep target illuminance under clear sky conditions. The system failed under overcast sky conditions since the electric light output from fixtures caused excessive signals to photosensors due to insufficient daylight on a desktop. Unshielded and fully-shielded conditions were not recommended for effective controls of the systems. The influence of lighting fixtures on photosensors should be minimized to achieve successful lighting controls by daylight dimming systems.
