A Study of Optical Characteristics for High Intensity LED

고휘도 발광다이오드(LED)의 광학적 특성에 관한 연구

The LEDs are used for signal lights including traffic signals and telecommunication equipments. Advanced foreign countries are making R&D of ultra high intensity LEDs, and the LEDs are expected to new light source. Optical characteristics by measurements of 14 LEDs; each 2 of 3$\Phi$ R/G/Y LEDs, each of 5$\Phi$ Y/G/Y LEDs and each of high intensity 5$\Phi$ R/G/B/A/W LEDs. Comparison on chromaticity coordinate of high intensity 5$\Phi$ White LED by forward V/I.
