Problem Statement

We recognize the technology push to develop
applications for a low voltage DC power
distribution system.
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
Specifications



Safe and be up to code with any standards
involving the commercial workplace.
100W, 24V, DC source.
Commercially valuable as apposed to residentially.
Identifying Customer Needs

Commercial Building Spaces need efficient lighting
designs that minimize excess energy usage.
 Office Spaces
Customers Requests from Survey
More accessable outlets
Heating/ Cooling
Security Features
Number of Instances
Aesthetics
Energy saving features
Movable lighting

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.
