Problem Statement
We recognize the technology push to develop applications for a low voltage DC power distribution system.
![Page 4: Armstrong “The Ceiling of Tomorrow”](https://reader030.vdocuments.mx/reader030/viewer/2022032805/56813326550346895d9a0bd2/html5/thumbnails/4.jpg)
Information Gathering
DC electricity has a few important advantages over conventional AC electricity: Higher power transfer capability Less voltage drop along the line Lower line resistance

Design Objectives
Must be an efficient lighting system that minimizes excess energy usage.
Efficiency is most important, followed by ease of use, aesthetics, cost, and maintenance.

Concept Generation
Adjustable Intensity Lights: Dimmed to desired intensity for individual
cubicles. Can be directly pointed to the desired area. Wireless control system.
Infrared Sensor: Automatically turns lights off if there is no
motion in the lighted area for two minutes.

Concept Generation
Adjustable Hydraulic Ceiling: Lowers so lights can be closer to
workspace. Raises to increase the volume of the room
as needed.

Concept Generation
Parallel Rails: Set of two interconnected parallel rails. Objects can be moved without being
unplugged. Outlets from Ceiling:
Devices can be plugged into the ceiling.

Concept Selection and Testing Adjustable intensity LED lights and
passive infrared sensors will be combined.
Surveyed consumers were satisfied with this design solution.

Final Design and Documentation
Elation 5watt LED Lamp –runs on DC, comparable to 50w Halogen
Aurora Ademco –Passive Infrared Motion Detector, Wireless

Summary and Conclusions
Our final design is to incorporate an LED lighting system which can be dimmed to the desired intensity and shuts off automatically if there is no motion in the lighted area for two minutes. The entire system utilizes wireless controls.
