Problem Statement
We recognize the technology push to develop applications for a low voltage DC power distribution system.Slide4
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 resistanceSlide5
Specifications
S
afe and be up to code with any standards involving the commercial workplace.
100W, 24V, DC source.
Commercially valuable as apposed to residentially.Slide6
Identifying Customer Needs
Commercial Building Spaces need efficient lighting designs that minimize excess energy usage.
Office SpacesSlide7
Design Objectives
M
ust be an efficient lighting system that minimizes excess energy usage.
Efficiency is most important, followed by ease of use, aesthetics, cost, and maintenance.Slide8
Concept Generation
Adjustable Intensity Lights:
D
immed 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.Slide9
Concept Generation
Adjustable Hydraulic Ceiling:
Lowers so lights can be closer to workspace.
Raises to increase the volume of the room as needed.Slide10
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.Slide11
Concept Selection and Testing
Adjustable intensity LED lights and passive infrared sensors will be combined.
Surveyed consumers were satisfied with this design solution.Slide12
Final Design and Documentation
Elation 5watt LED Lamp –runs on DC, comparable to 50w Halogen
Aurora
Ademco
–Passive Infrared Motion Detector, WirelessSlide13
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.Slide14
