This paper analyzed adaptability optical performance of an intelligent LED lighting fixture capable of variable CCTs (3,000K, 5,000K) replacing a fluorescent lighting fixture applied in a underground common duct. In addition, visibility of a camera was tested under a low light condition to save energy. As a result of simulation using the IES File of the LED fixture generated by light distribution measurement, the average illuminance of the LED fixture was improved by about 2 times compared to that of the existing fluorescent lighting fixture. In addition, the installation distance between the LED fixtures was increased from the current 5m up to 10m to save more energy. The visibility of the camera image was confirmed by two methods of adjusting the distance under the same low illumination condition and the illumination adjustment method.

This study proposes a program that utilizes Philips Hue smart lighting to change its color based on real-time bus arrival information when users input city name, bus stop name, bus stop number, and route number. The developed program leverages human visual perception, allowing users to easily perceive their departure preparation time through simple changes in lighting color and eliminating the inconvenience of traditional bus arrival notification applications. This efficient system aims to assist busy modern individuals in managing their time effectively and enables them to stay informed about necessary notifications or specific situations while engaging in indoor activities. The expected outcome is to provide an efficient lighting environment that enhances daily living by combining practicality and convenience.
