To live comportably, proper air and lighting environment are necessary, environment is obtained by excuting. We can get the lighting environment with excuting day-lighting and artificial lighting suittably. The developing trend of fluorescent light lamp call for low power and high lighting efficiency. Nowadays, The 26 mm FL is developed and in wide use in this proper, the character of 26 mm FL is discussed, same improvement are proposed.

The environmental lighting of a city advances its landscape standards and the city's touristic value because the lighting can help improve the city's safety and security as well as its esthetic value. The types of parks in cities vary in size and function and should be reflected carefully in lighting planning to gain the best effect. The importance of city lighting has been increased in recent years due to the expanded span of urban night life. Lighting systems around rivers and coastal waterfronts in cities play an important role not only in their functional aspects, such as safety and security, but also in boosting the city's identities. This paper performed comparison analysis among Tsim Sha Tsui Promenade in Hong Kong, Fukuoka Nakagawa Park in Japan, and the walking path in Hamdeok Beach in Jeju City, Korea. According to the evaluation, Hong Kong is excellent in 8 evaluation criteria for park lighting so that the city shows its superior installation and management. Fukuoka is also good by being analyzed as 'fair' in 5 criteria. Finally, Jeju is judged as inferior overall by showing 'poor' in several criteria. The paper shows how they differ in their environment lighting characteristics and aims to suggest stable lighting planning strategies for seaside parks in Jeju so the citizens and visitors of Jeju can enjoy the beautiful sceneries and nighttime activities.

Outdoor lighting is an important factor of urban scape. As a night image of the city, outdoor lighting acts important roles. Cities of developed countries have already had night images of their cites. About this, government is encouraging outdoor lighting of building by various ways. However, in present, outdoor lighting of headquarter buildings was not activated more than that of public buildings in our country. From this point of view, this paper presents a method to measure outdoor lighting effects as quantitative aspects for outdoor lighting activation. Presented the method of outdoor lighting effects is difficult to apply all buildings. Therefore, this paper limits the target to the headquarter buildings.

Outdoor lighting is an important factor of the urban scape. As a night image of the city, outdoor lighting acts important roles. Cities of developed countries have already had there own night images. Regarding this, government encourages outdoor lighting of building by various ways to building owners. However, in present, owners of private buildings have not been up and coming about outdoor lighting more than those of public buildings in our country. From this point of view, this paper suggests a quantification method for economic effects of outdoor lighting and analyzes economic effects of outdoor lighting in advertising. A suggested measurement method of economic effects is difficult to measure all economic effects of outdoor lighting. Therefore, this measurement method limits the target to the private buildings.

The purpose of this study is to propose a simulation approach which compares lighting quality of each luminaire type for small urban park users' safety. For improving illumination quality, lighting intensity distribution of a luminaire is one of the important factors and it is also important to set the luminaire to a proper position. To achieve the best plan for illumination, it is most important to communicate the plan with designers of park and professional engineers in depth and the communication continues from the beginning of the plan.

Generally, the phase control dimmer has been widely used due to simple interface and easy handling. However, the electrical characteristics are not good for the method in which the phase control dimmer cuts the input voltage. This paper has researched about DALI(Digital Addressable Lighting Interface) controller, that is the digital lighting control method, and implemented DALI protocol satisfied with the IEC-62386 standard. In addition, the existing phase control dimmer was used as the controller of DALI and not only individual control but also group control was possible. And the performance was proved to be good by applying our theory to 30[W] LED lighting control system.

In this thesis, we designed specific LonWorks nodes for lighting control then implemented the lighting control system through the operating scenarios. Developed lighting controller plays a role of one network node and according to information from other nodes, decides whether it toms on the light or not. In this way the lights can be controlled by using the location information of light in the lighting control node and the grouping information of the lights in the switch node.

Recently, rapid development of technique and change of lifestyle during nighttime has activated the urban outdoor lighting and renovated consideration of nightscape. As the interest of nightscape increases more widely, outdoor lighting has been installed more and more in the cities. Nightscape comes in diverse forms. So, there is no absolute standard for outdoor lighting. But only bright outdoor lighting is not necessarily a good nightscape. Installation lighting without master plan or excessive outdoor lighting may cause a inharmony. This study aims to analyze the luminous characteristics of facade in shopping complexes. For the purpose, four large-scale shopping complexes located in Dongdaemun area were selected. Building facade composition, outdoor lighting composition, and lighting equipment of each shopping complexes are surveyed, and luminance of building facade were measured with Prometric 1400. The result of the study are as follows; (1) Horizontally large-scale shopping complexes emphasize the building entrance and shape of the building at night by outdoor lighting. (2) Non cut-off luminaries installed in building entrance and shop front caused the potential of light pollution.

Lighting industry is rapidly being developed as the ubiquitous society based on sensor network emerges. This kind of paradigm shift brings the society convergence of technologies which leads to smart lighting system as well as the integration of interior and sensibility control. However, standards for sensors have not been firmly established, and problems related to quality and malfunction have been brought up, thereby calling for careful approach to the enhancement and assessment of reliability of the item. In this article reliability assessment criteria for sensor module for lighting fixtures is established in terms of performance assessment criterion and reliability assessment criterion.

Night-Scape Lighting with the use of LED lighting has become very popular recently by the merits of energy saving, environmental friendlyness, sensitivity and conversion trends. LED lighting designs are being used diversly as outer elements for screen media stage production as well as buildings with fusioning of information technology. However, methods for analyzing the cases effectively are far from completion. This research evaluates the recent trends of Night-Scape Lighting with LED and processes it through database and aims to propose LED Night-Scape Design process for the various architectural night-scape lighting designs.
