MS in Lighting: Related research projects

Students in the Master of Science in Lighting program will undertake unique research under the guidance of a faculty advisor. Some examples of recent student research projects include:

LED refrigerator/freezer case lighting

The rapid development of high brightness light-emitting diodes (LEDs) has triggered many applications, especially in the area of display lighting. This study focused on the application of white LEDs in refrigerated display cases. The fluorescent lighting presently used in commercial refrigerators is inefficient in the application and provides poor lighting for merchandising. Researchers conducted a laboratory human factors experiment to assess the preference for fluorescent and LED lighting systems.

Light dimming for load shedding

Lighting presents an opportunity for load shedding and potential energy cost savings. Dimming office lighting can ease peak demands for energy during periods of critical need. This thesis research focused on the light level requirements of office workers to carry out their normal routines. Studies determined how much reduction in lighting levels the workers would accept while still performing their work productively.

Evaluating white LEDs for outdoor landscape lighting application

LEDs are good potential light sources for exterior landscape lighting in terms of ruggedness, efficiency, small size, low voltage, durability, and long life. The goal of this study was to understand the acceptability of different white LEDs in comparison to popular halogen sources for outdoor landscape lighting applications. The application addressed in this study is the exterior of a building and landscape lighting such as along pathways, steps, flowerbeds, and near small shrubs. Two types of white LEDs (down converted phosphor and red-blue-green) and halogen light sources were evaluated in an outdoor landscape setting.
