1 LED Lighting Applications What Works & Why It Was Chosen Presenter Information Randall S. Johnson, LC President US Lamp, Inc. Green Bay, WI Presenter Information Kerm King Energy Manager School District of La Crosse La Crosse, WI

2 Presenter Information Don Keck Buildings and Grounds Manager Stevens Point Area Public Schools District Stevens Point, WI Agenda Lighting Trends LED as a technology Why choose LED over other lighting? Examples and strategies LED advantages High Efficacy Fixtures can achieve LPW efficacies 5 10 LPW for incandescent Longevity Useful life of 25,000 to >100,000 hrs <1,000 for incandescent Environmentally Friendly No hazardous materials ex: mercury vapor in CFL lamps 2

3 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

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

Current products are at 80-205 LPW-depending on category Everyone is making LED products-pick vendors wisely!

4 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 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 ,000 LED products 9,403 TLED bulbs listed October of ,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 4

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.

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!

5 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!

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! Redesign-HID to HIF T5HO 7

Consider white light, especially in low-illuminance conditions or for aesthetic appearance. Put light only where needed. Avoid light pollution (lighting up the sky), and light trespass (lighting neighbors property). Avoid glare from floodlights, wallpacks, dusk-to-dawn units and bright post-top units. Use automatic controls. All off or half off after midnight, for example. All off during daylight hours. Good application for wireless controls. 11

produced (reduce power - kw) Code Requirements State and Federal control mandates Productivity When building occupants

14 Building Entrance - HPS to LED Before After 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 Requirements State and Federal control mandates Productivity When building occupants control their lighting, they are more productive Lighting quality Match appropriate light level to task Increase visual comfort Security Automatic switching or occupancy sensing 14

15 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 15

Occupancy Sensor: Application Savings Tier 2: Why dim LEDs?

component life (electronics & phosphor) Double or triple lumen maintenance General dimming benefits Enhance ambiance Space flexibility Improve safety

16 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 16
