The main issue of this thesis is a comparison of traditional T9 fluorescent, T5 fluorescent lamps, and Light Emitting Diode (LED) in campus classroom. First, the author measures illumination of classroom using a digital instrument. Then, a lighting simulation software is implemented analysis for T9, T5, and LED lights. This software can output different analysis results such as: (1) power consumption, (2)illuminance distribution ( i.e., maximum, minimum, and average illuminances),(3) electricity tariffs in accordance with Taipower company. The research results can show up the effective of LED in campus lighting.
