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

Movable lighting

Energy saving features

Aesthetics

Security Features

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.
