Transcript of Educational LED Lighting

LED light contains the same light spectrum as the sun, making it the most "natural" artificial light choice.
Humans (and animals) need a strong, regular reception of light daily or our Circadian Rhythm (body clock) malfunctions.

Certain wavelengths stimulate specific hormones in the human body, ie., blue = alertness (at noon), red and orange = melatonin for sleep (in the evening). Think of the color of the sky throughout the day.

Studies have shown that exposure to full-spectrum LED lighting can:
-Lower stress and anxiety
-Significantly improve productivity
-Stimulate positive health and behavior

In students, many "learning disabilities" are greatly improved by full spectrum LED lighting such as hyperactivity, depression, aggression and disorderly conduct.

Light Therapy
- Red LEDs are being used to reduce the effects of aging, heal skin wounds, improve skin diseases such as eczema, and treat brain tumors.

What Makes LED Different?
Today - Philips Lumiled
Year 1968 - 5mm T1 ¾ LED
The first practical LED invented in 1962 by Nick Holonyak Jr. at General Electric Company

Late 1960s – Red LED available commercially.
Mostly used as indicators on electronic equipment and
eventually appliances.

1993 – High-brightness blue LED developed by Shuji
Nakamura of Nichia Corporation. White light followed
soon after.

Advances in heat dissipation technology eventually
allowed light bright enough for illumination.
What is LED?
LED, or Light Emitting Diode, is an electrical component with two terminals which conduct the electricity in one direction. With a positive electrical current, the diode emits light.

Color is dependent on the energy gap in the
semiconductor of the diode.
Larger gap = more blue light
Smaller gap = more red light

Background and How It Works
How does it work?
Small size and low profile

Direct light focus
- Light is directed without a reflector

Energy and cost saving
- Low heat production (Incandescent bulbs give off 90% of energy as heat)
- More lumens per watt
- Lasts up to 50 times longer than traditional lighting. (Less maintenance)

ON instantly
- No lag in switching time and frequency of switching does not effect bulb life.

No glass - Stronger and breakage resistant.

LED and Human Health Benefits

The Future is Bright for LED
When will you "make the switch?"
LED is the inevitable solution to our future lighting needs.
We see LED Lighting Clearly
EcoSafe Lighting is a service-oriented lighting company, helping our clients achieve the benefits of LED lighting solutions. We emerged from a regional construction and development team that saw the potential of LED lighting to revolutionize the way businesses and governments think about and use lighting.

Our solutions approach includes:

Assessment – floor map based upon lighting needs
Design – lighting plan achieving efficiency, effectiveness
Sourcing – seek overall value, with rebates, incentives – quality assurance.
Installation – minimal disruption, LED-experienced crews
Support – monitoring, changes, warranty service
LED and the Color Rendering Index (CRI)
The color rendering index (CRI) of a light source is a quantitative measure of its ability to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source. The sun has a CRI of 100.
LED developers including Philips, Cree, Sylvania, and LEDnovation have come up with A19 bulbs with CRIs ranging from 90-95. These are far more exceptional replacements for the traditional incandescent bulb.
High-efficiency "L-prize" bulb from Philips with a CRI of 92
Luminous Efficacy

What makes LED different?
What makes LED different?
The luminous efficacy of a source is a measure of the efficiency with which the source provides visible light from electricity and is measured in lumens/watt.

Because incandescent bulbs rely on thermal emission from a tungsten filament, much of the energy produced is in the form of heat and ultraviolet/infrared light. Due to the light spectrum control available with LED and the lack of heat to produce light, a considerable amount of wattage is saved.

EcoSafe Lighting provides essential lighting design, sourcing, installation and support across a broad range of industries, to help facilities staff quickly and painlessly achieve the full benefits offered by LED lighting solutions.

EcoSafe Lighting solutions help you:
•Improve lighting quality and controls
•Improve worker and customer safety
•Reduce energy costs
•Reduce maintenance time and costs
•Reduce environmental impact and costs
•Stabilize HVAC usage costs
•Eliminate mercury waste disposal issues
•Eliminate UV radiation exposure

Lighting the Way
Our goal is to help private enterprises and public entities deal with their energy costs and consumption by offering a single source for lighting design, installation, project management, incentive capture and warranty support.

By providing the right light in the right space at the right time, the door is open to significant operational improvements.

We want to be your LED lighting partner. Our objective is to make it easy and painless for you to realize the full benefits of LED lighting systems.
