A Basic Study on Improvement of PLS as a future Lighting by Prospect of Global Demands and Analysing Lighting Technology

Global 조명수요 전망 및 조명 기술 분석을 통한 미래 조명용 PLS 발전 방향 모색

After an incandescent lamp developed as a first light source using electric energy in 1879, various lamps have been developed and promoted for usual convenience. Although lots of light sources have been developed for the past centry, among them some were used widely but some were hardly used contray to the initial expectations. Incandescent, fluorescent, HID and LED lamps which are normally used these days were treated as new type of light sources and very difficult to be popularized at the initial stage. In spite of the initial difficulties, these light sources and luminaries are still so popular because all of them were improved to be used easily by reflecting human's mental and physiological state. Like this when new light sources and luminaries are developed, a careful consideration, if these are proper for the surroundings or not, must be preceded. This study finally derived development factors of PLS developed in domestic to be played an important role in future light by analyzing product trends, social and lighting development changes.
