전통적인 조명이 고효율 LED(Light Emitting Diode)로 빠르게 대체되고, 에너지 효율의 극대화를 위한 다양하고 효과적인 조명 제어 기술이 요구되고 있다. 본 논문에서는 LAN(Local Area Network)과 PAN(Personal Area Network) 기반의 유무선 통신기술을 이용하여 다양한 방법으로 LED 조명을 제어 할 수 있는 조명 제어 장치를 설계하고 구현한다. 구현된 장치는 조명 설치의 복잡한 배선 작업과 설치 작업 비용을 절감하고, 필요한 곳만 선택적으로 자동 또는 수동으로 조명을 제어할 수 있도록 제어 장치를 설계하여 전력 소비량을 최소화할 수 있다. 실험을 통해 개발된 LED 조명 제어 장치의 기능이 정상적으로 동작함을 확인하였다.

In this paper, We developed specifications light-way lighting appliance for efficient construction Wiring embody lighting appliance is convenient for divergence of circuit and arrangement construction of lamp. Also, it can be shortened construction period because series construction is available. Improved product is high work efficiency because the volume is small and the weight is light. Power line and line of communication are received each tray, so equipment is secure. We believe that the product is available for gallery, museum, and parking lot etc.

This paper presents an LED lighting which can control its color temperature. It consists of a power factor correction (PFC) circuit, an LED driver, and an LED color control circuit. The proposed system can adjusts the light intensity to obtain a desired color with independently changeable illuminance. The power factor of the PFC circuit is 98%. The LED driver has 90% efficiency at 300mA output current. The output power of the experimented LED lighting is 150 W. The achieved color temperature range was from 3000K to 7500K, and the illumination one was from 500 lux to 1500 lux.

In this paper, we measured the optical characteristics of the electrodeless fluorescent lamp system as product of the inside and outside of the country and compared the measured data. Power consumption wave of domestic 150 W is unstable than it's of Endura 150 W. Optical characteristics(luminance, luminous flux, color rendering index, efficiency, CIE chromaticity coordinate) value of the former is a little small than the latter. In conclusion, if we improve a little more quality then we must secure the superiority in competition.

For a human being's smooth activity, the clean air and comfortable lighting environment are needed. The suitable lighting environment is obtained generally by making it available for being formed the bright situation easy for seeing object and the visually comfortable atmosphere. In this way, even the lighting environment was changed along with economic development. Even a light source was diversified. Thus, several kinds of new light sources such as LED, OLED, PLS, and CNT came to appear. Halogen lamp, which has low efficiency due to high color rendering among lamps of being used now, is being much used yet. However, owing to radiation of UV and IR, there are many limitations to the subject in general exhibition lighting, museum, and art museum. Accordingly, a research was performed on filter that is blocked UV and IR at the same time, by using halogen lamp that is excellent in color rendering and in life.

The efficiency of LED package is increasing by applying the high power, and a existing lighting is changing as the LED lighting. However, many problems have appeared by heat. Therefore, in order to solve thermal problems, LED lighting is designing in several ways, but the advantages of LED lighting is fading due to increase the prices and volumes. In this study, we try to improve the thermal performance by formation of via holes. The junction temperature and thermal resistance in the FR4-PCB with via-holes of 0.6[mm] was excellent in experiment and FR4-PCB with Via-holes of 0.6[mm] was excellent in simulation without solder. Further, the thermal resistance and the optical properties can be improved through a formation of via-holes.

Today, energy problem has become an important issue, and a development of renewable energy is urgent. In architectural fields, a research of the energy efficient lighting system using renewable energy is in progress. The energy efficient lighting system could be realized by integrating a daylight responsive LED lighting control system and a blind PV system. This system is able to save and generate electric energy. Efficiency of this system depends on control methods of blind PV. As a preliminary research, this research analyzed power generation and inflow of available daylight according to control method of blind PV.

Machine vision systems is applied for various industries such as optimize your spending, automate your production and maximize your efficiency. This research is effective for most optimal light condition of machine vision that technology was applied bald outside human visual acuity. Image processing converts a target image captured by a CCD camera into a digital signal and then performs various arithmetic operations on the signal to extract the characteristics of the target, such as points, lines, circles, area and length. The mathematical concepts of convolution and the kernel matrix are used to apply filters to signals, to perform functions such as extracting edges and reducing unwanted noise. This research analyze and compares matching ratio with reference image and search for optimal lighting condition in accuracy that user wants coming input image according to brightness change of lighting.

In this paper, I try to measure characteristic transmission-reflection by environmental change or solar cell. I keep my eye on the characteristics variation of solar cell as environmental change. As a result, A variation caused by voltage by an effect on the efficiency of solar PV cell. Hence, it is an important variable when a designer plan to make a solar cell.
