The purpose of this paper is to determine circuit parameters in the inverter part of the electronic dimming ballast for fluorescent lamps, that is adequate to use with the prevailing dimming controller IC. Firstly, the operating frequency characteristics are investigated by varying circuit parameters of electronic ballasts and are matched with the output characteristics of dimming ballast controller. Secondly, circuit parameter values are determined by using PSpice simulation and operating frequency characteristics. Finally its validity is verified from the electrical and light output characteristics on the prototype of the electronic dimming ballast.

Recently, lighting systems of vehicles have been developed toward low power, high energy-saving, and efficient control of light distribution. This paper aims to survey such trends, and to present prospects of advanced lighting systems of vehicles. Emphasis is laid upon the use of high-brightness LED and HID lamps which will be sportlighted in the near future as signal lamps and head lamps of vehicles, respectively. The discussion includes future prospects of lamps and luminaires, and the control of lighting system of vehicles.

이 논문에서는 100W급 Discrete LED 투광기 조명 제품 개발에 관한 것으로, 3W RGBA LED를 이용하여 광색 및 색온도 제어가 가능하도록 광학/방열/회로/시스템 설계를 통한 시제품을 제작하였다. 그 결과, 색온도 2,000-10,000K 범위에서 흑체궤적에 정확히 일치하면서 연색지수가 71~91까지 고연색성을 실현하였으며, 동작전압 90~250VAC, 효율 87%, 역률 93이상의 양호한 전기적 특성을 나타냈다. 또한 투광기의 협각/중각/광각 배광을 만족하기 위하여 LED 렌즈를 설계하였으며, 신뢰성 확보 및 주위온도에 따른 광출력 변화를 최소화할 수 있는 방열설계를 실시하였다.

This paper suggests the driving circuits of constant voltage, square wave, triangle wave, sine wave DC current control method for LED array adopted optimal heat sink design. The efficacy of LED bulb with all driving circuits showed more than 70% and 20 lm/W. In case of applying prototype LED bulb as a recessed downlight fixture, LED bulb showed high efficiency of 90% because of LED"s directivity despite low optical output and luminous efficacy than CFL. Consequently, we confirm that LED bulb can be apply to the practical use..

Although LEDs have been used in various applications with improving the brightness and luminous efficacy, the electrical and optical characteristics of high power LED varies at different temperature and starting time. In this paper, optimal heat sink and apparatus design were conducted using ill camera and ICEPAK on the LED bulb consisting with fourteen LED array. The temperatures of heat sink and LED device of the designed LED bulb without cooling pan were 74℃ and 96.8℃, respectively, showing in good thermal characteristics. For high efficiency driving circuit of LED array adopted optimal heat sink design, driving circuits of constant voltage and current circuits were suggested and fabricated. As a result the efficacy of all driving circuits showed more than 20 ㏐/W. Also, the constant current circuits are suitable for signal lamp, hallway lamp, and flash lamp having short operating time(about 30 min). On the other hand, a reading light and indoor lamp having long operating time can be controlled by constant voltage circuit.
