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

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.
