Reasons to choose LED

• Desire to be “Green”

• Reducing energy, not financially driven

• Reducing pollution-good for the planet

• To be on the ‘Cutting Edge”

• Federal, State, Utility grants to help with “First Cost”


Why do we light a space?

To provide the correct seeing environment to properly perform your activity

Create an aesthetic, pleasing space

Provide a safe environment

NOT to save energy-lighting consumes energy!


Industry Trends for LED

Light Source Efficacy – LPW 2009

LED’s or SSL:Light Emitting Diodes (LEDs) are solid-state

semiconductor devices that convert electrical energy directly into visible light

Heart of an LED is composed of combinations of these elements, often called a “die” or “chip”

Actual junction of the elements is called the “P/N junction”


Where is LED lighting headed?

• Current products are at 80-205 LPW-depending on category• “Everyone” is making LED products-pick vendors wisely!• Strong emphasis on increasing efficiency – Cree has 305 LPW in

the lab• Many good point source products• Industry push to replace general lighting products- most

product improvement is evolving here• LightFair International has >500 manufacturers - all but a

handful display LED products• DLC (Design Lights Consortium) MA-Clearing House for rebates

– Summer of 2016 177,000 LED products 9,403 TLED bulbs listed– October of 2016 232,709 LED products 12,893 TLED bulbs listed


LED Product Categories

• T8 bulb retrofits• Fluorescent fixture replacements• Outdoor wall pack fixtures• Parking lot fixtures• Task lighting• Landscape lighting• Flood and spotlight fixtures• Canopy lighting• Cooler/Freezer lighting• Retail store lighting sending ads to iPhone

Critical issue with LED Performance-Heat dissipation

• LED’s produce heat into circuit board

• Heat management and removal is critical to proper performance and life ratings

• 50,000 hr. rating in laboratory setting-may be considerably shorter if heat is not addressed

• LED’s work better, in colder ambient temps.

• Proper fixture design must address heat removal

• Be careful of new product with 5 or 10 year warranties from 2 year old companies!


Make sure you select the

right equipment for the right application!


LED T8 Retrofit Tubes: Generation 3, 4, 5, 6

• Improvements:Lower watts (Gen 3)

External driver (Gen 4)

Retrofit: ReflectorsFluorescent kits available

■ Example: 2x2 w/2, U-tubes to 2 or 3, 17-w T8 tubes

Improve troffer efficiency

Relocate tubes for max performance

Perform trial installation

Evaluate cost of retrofit fixtures versus replacement

- Alternative could be LED panels or retro kits

Retrofit or Redesign?• Evaluate the quality and appropriateness of the existing lighting

system.– A retrofit may replace lamps, ballasts, or fixtures but must not drastically

change the overall lighting function.

– A redesign will involve a whole new lighting system, often with quite different components and performance characteristics than the original.

• The cost of a lighting system improvement is often proportional to its permanence!

Controls


Why Use Controls?

• Energy and cost savings (35 – 50%)

Reduce time lighting systems on (hrs-of-use)

Dim so no more light than necessary produced (reduce power - kW)

• Code RequirementsState and Federal control mandates

• ProductivityWhen building occupants control their lighting, they are more productive

• Lighting qualityMatch ‘appropriate’ light level to task

Increase visual comfort

• SecurityAutomatic switching or occupancy sensing


10/19/2016

Lighting Control Strategies

• Switching (manual or automatic)

• Scheduling (lights off when not needed)

• Tuning (ensures right qty. of light at the task)

• Daylight Harvesting (responds to changing conditions)

• Lumen Maintenance (compensates for depreciation)

• Demand Limiting (sheds or dims lighting at peak times)

• Demand Response (utility requests to shed load or automatic)


Tier 1: Occupancy Sensor Controls

• Occupancy sensors can save 25%-80% or more in energy costs.

• Infrared/Ultrasonic/Dual Technology/Microphonic

• Dimming/Daylighting controls can reduce energy costs and extend lamp life.

• Use ballasts appropriate for switching to maintain rated lamp life!

• Wireless controls by several Mfg.


Occupancy Sensor Types

• Infrared (PIR)

• Ultrasonic

• Sound Activated

• Dual Technology

infrared + ultrasonic

infrared + sound activated

occupancy sensor + daylight inhibit

Occupancy Sensor: Application Savings


Tier 2: Why dim LEDs?

• Dimming LEDs saves energy– 50% dimming = 50% energy savings

– Added savings to an already efficient source

• Dimming lowers operating temperatures– Extends component life (electronics & phosphor)

– Double or triple lumen maintenance

• General dimming benefits– Enhance ambiance

– Space flexibility

– Improve safety

– Increased productivity


Dimming Performance-Potential LED aesthetic issues:

– Flicker - The unexpected modulation of light level that is perceptible to the human eye (not always visually seen!)

– Pop-on - The level the light is at when it is turned off is the level it should return to when it is turned back on

– Drop-out - The light should only turn off when the switch is turned off.

– Dead-travel - Adjusting the control without a corresponding change in light level

– Audible Noise - From control or lamp

– Popcorn - Multiple lamps on the same control turn on at different times Midwest Facility Masters Conference 11-8-16

Tier 3: Wireless Occupancy Sensors & Relays

• Ceiling mounted PIR occupancy sensors that communicate with wall-box unit (or wireless relays) using RF

• Requires NO hard-wiredelectricity

• Ideal for retrofit applications

• Some units use long-life battery• Ideal for dimming applications

• Others use no battery• PV cells in sensor keep capacitor charged

• Relays operated by RF from sensors


Wireless Sensor Advantages

• Competitive cost to wired sensors

• Same or better coverage patterns

• 1/3 or less labor for installation

• Perfect for hard ceilings and inaccessible areas

• Can be integrated into more comprehensive building-wide energy management controls

• Extremely flexible, to “build as you go”
