Project Plan Presentation P0842X – LED Lighting

Technologies

Why LEDs?

RIT spends approximately $6 million on electricity every year Half goes towards lighting (~$3 million)

LED Reduce energy consumption Longer lifetime

Lower maintenance costs Less waste

Environmentally friendly

LED Information

Efficacy Light output divided by power

input LED 30 lumen/watt Future LEDs 150-200

lumen/watt Fluorescent Light 85

lumen/watt Incandescent bulb 16

lumen/watt Color Rendering Indices (CRI)

CRI measures fidelity of the colors of objects reflecting the emitted light

LED Vary from 62-91 Incandescent bulb 100 Metal Halide ~85

Color Temperature Degree warmth or coolness of a

light source LED 5000-7500 (cool white) Metal Halide 3000 K (very

yellow) to 20000 K (very blue) HPS 2700 K

Lifetime LED 100,000 hours Incandescent 1000 hours Fluorescent 10,000 hours

Diagram Representation

Team Values and Norms

Punctual Each team member will arrive on time and will notify fellow team members of any expected absences. It is important that the team member ensures that at least one member of the team confirms the notification

ThoroughEach team member is expected to do their assigned work in a manner such that it does not have to be redone by another, and if they feel that they have been assigned too much work to do that they seek out help from other team members or faculty consultants

AccurateEach team member will accurately complete and document their work

Professional and EthicalEach team member will credit work and information to the proper sources and will be trustworthy in all of their dealings.

Demonstrates the core RIT values of SPIRIT.Each team member will remember that they are representing RIT and as such the reputation of RIT and the SD program are reflected in their work.

CommittedEach team member will contribute an equal share to the success of the project and commit to the challenge set before them with the understanding that the SD process should a fun and informative

Grading and Assessment

Preliminary Grading SchemeGrade Level Senior Design I Senior Design II

DHave multiple concepts in the works with a semi-clear plan for executing at least one of them

Have completed concept development for at least two of the original concepts and have a project production plan for one of the concepts

C Have a concept singled out and in the process of being completed

Have finished concept development and begun working on the final project

B Have a working concept nearly developed Have finished the bulk of product

A Have finished concept development and are ready to proceed with fabrication Have a completed working product

Issues and Risks

Economic Funding

Secure from FMS and EE Department Environmental Protection Agency P3 Grant

Mission Statement Walkway Metal Halide Replacement

This specific project will focus on developing a replacement for the Metal Halide walkway fixtures that are located around campus. These metal halide fixtures aim provide a good return on the investment as well as an efficient light source. The LED fixture needs to be energy efficient, cost effective, and easy to maintain.
