초록

본 논문은 다면체 반사판(Multifaceted Reflector :MR16)을 사용하여 할로겐 광원을 LED광원으로 대체함으로서 기존 MR16의 장점을 수용하고 더불어 단점을 커버할 수 있는 MR16에 대해 연구하였다. 본 연구에서는 4매의 비구면 렌즈를 1 Sheet로 한 광학계를 적용한 LED용 MR16을 개발하였다. 광학 소프트웨어를 통해 비구면 광학계를 설계하였고, 조명 시뮬레이션 프로그램을 사용하여 설계 데이터의 조명성능을 예측하였다. 또한 방열 해석 프로그램을 통해 Heatsink의 열 성능을 예측하였다. 최종적으로 시뮬레이션 분석 데이터를 토대로 광학 시제품을 제작하고, 직접 성능을 측정하여 설계데이터와 비교 분석하여 다음과 같은 결과를 얻었다. MR16의 배광각도는 $50^{\circ}{\sim}60^{\circ}$내외로 시뮬레이션 분석 결과와 시제품의 측정결과가 유사하였으며, 온도측정 결과는 1분 30초경부터 열 평행을 이루었고 이의 시뮬레이션 결과와 시제품 모두 최대 $60^{\circ}C$까지 열이 오르는 것을 확인하였다. 마지막으로 MR16의 배광곡선 역시 제작된 시제품의 성능측정 결과가 유사함을 보여주었다.

This paper studies MR16 that can strengthen the strength and make up for the weakness of MR16 by replacing halogen light source using multifaceted Reflector(MR16) with LED light source. To achieve this, developed MR16 for LED applying optical system that four aspheric lens is one sheet. Optical system is designed by optics software and lighting performance of the designed data is predicted lighting simulation program. Also, heatsink's heat radiation analysis program to predict the thermal performance. Finally, optical prototype system based on simulation analysis data is manufactured and the results comparing performance of the developed system and the designed data are follows: Radiation angle was around $50^{\circ}{\sim}60^{\circ}$ in results of simulation analysis and the test of the prototype system. Also, temperature measurement result indicates that the thermal equilibrium is realized after one minute and thirty seconds and heat is generated up $60^{\circ}C$ in all of simulation analysis and the test of the prototype system. Finally, simulation analysis result on light disturbance curve of MR16 is similar to that of performance of the prototype system.
