This is the Drexel Engineering 103 blog for group 068-06. The goal of this lab is to create a LED fixture that can be implemented into a dementia ward at St. Francis Country House to help the health of the patients there. We are working with Group 068-05 to achieve this goal of creating a working prototype. Our group is primarily focusing on the manufacturing of the physical light fixture while the other group is working on programming the LEDs to simulate daylight.

Center Heat Sink Design Plan


This image shows the design plan for the center heat sink for our prototype.  There will be about twenty of these stacked on top of each other with washers in-between.  This will allow for greater airflow to the LEDs which will allow them to stay cooler and last longer.  The hole in the center will allow for wring to pass through to the LEDs and keep the overall look of the fixture cleaner.  The LEDs will be four strips of LEDs mounted to the center of the light and they will attach to the inner square.
