5 What is Light? Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm)

6 What creates light? Incandescent bulb Fluorescent bulb
Heating of a filament by the current flowing through it creates light through incandescence Fluorescent bulb An electrical arc passing through a mercury vapor creates UV rays which strike phosphors coating the inside of the glass tube. These phosphors emit photons (fluoresce) in very narrow wavelengths Light Emitting Diode (LED) bulb A solid state device (P-N Junction semiconductor) that converts electrical energy directly into light through a process called electroluminescence

7 LED Basics P-Type matrix with electron hole
N-Type matrix with free electron Free electrons cross the junction to fill the holes. Energy released during this transition is in the form of light (heat in regular diodes)

8 So what is so special about LED-based lighting?
An LED is a solid state device with no filament or high voltage arcs In basic form, LEDs are a highly efficient monochromatic light source Monochromatic LEDs are by far more efficient than any other available light source (10 to 50 times) White LEDs are manufactured by combination of blue or near UV LEDs with RGB phosphors White LEDs are one of the most efficient light sources (800% greater than incandescent, 30 to 50% greater than CFL) Very long life- in excess of 50,000 hours

9 AC LED Technology has many benefits
No need for a switch-mode power supply driver Less complicated design Fewer parts Lower chance of failure Improved circuit efficiency and lamp efficacy Greatly improve power quality Power Factor >.97 THD < 20% Operates at 120Hz, above the range of human/poultry frequency response (approx Hz)

10 State of the Market LEDs continue to gain investment, press, and market share Largest Market Opportunities Street/Area Lighting Office Lighting Home and Retail PAR30 A19 – W lamps

11 LED Developments 75-100W Announcements at Lightfair
$45-50 for home LED in 4Q Improvements in die-level efficacy

12 Commercial Lamp Comparison
100W Incandescent 23W CFL 17W LED (Lightfair Announcement) 75W Incandescent 18W CFL 13-15W LED 60W Incandescent 9-13W CFL 10W LED

13 Additional LED Reading
has many LED/SSL groups that are very active

14 Types of Light Sensitivity \ Photoreception: How do we “See”
Humans and Poultry Retinal Reception – Photon absorption by photo-pigments rhodopsin (rods), iodopsin (cones) and recently discovered (1998) melanopsin Poultry Pineal Reception - Photon absorption by functional photoreceptors located in pineal gland on the top of the brain Hypothalamic Reception - Photon absorption by deep encephalic photoreceptors

15 Retinal Photoreception - Domestic Fowl retina

16 Transmission of light via avian scull and brain tissue
Avian scull, skin and brain tissue create natural light filter. Due to the presence of blood in the tissue, red light penetrates scull with highest transmission efficiencies.

17 Human Eye Photopic Spectral Sensitivity

18 Retinal Photoreception
- Domestic Fowl Photopic Spectral Sensitivity (Typical) Data source: “Spectral sensitivity of the domestic fowl (Gallus g. domesticus)” N. B. PRESCOTT AND C. M. (1999)

19 Dimming, On/Off, and painted bulbs
The effects of artificial light on the performance of chicken There are three main aspects of the artificial light important to poultry producers Light intensity or the total amount of luminous power produced in the visual (for poultry) part of the light spectrum The photoperiod or number of hours of light and dark in a 24-hour period The spectral composition of the artificial light Dimming, On/Off, and painted bulbs

20 Red Color and Hue does matter…
Increases the growth rate of chickens and turkeys at the beginning of the rearing period Increases locomotion that helps minimize leg disorders in the late rearing period Stimulates and promotes sexual activity Reduces actual feed consumption per egg laid (up to 20%) with no differences in egg size, shell weight, shell thickness, or yolk and albumen weights Proliferate cannibalism in broilers

21 Green and Blue Color and Hue does matter…
Green light significantly enhances growth rate at an early age by enhancing proliferation of skeletal muscle satellite cells Blue light enhances growth at a later age by elevation in plasma androgens Green and Blue light promote myofiber growth due to more effective stimulation of testosterone secretion Narrow band blue light reduces locomotion Narrow band blue light reduce cannibalism rate at late age (broilers)

22 Why is the spectral composition of artificial lighting important in agricultural applications?

23 Almost all electrical lighting was created for human environments.
Because artificial light is quite different compared to natural daylight. Plus Almost all electrical lighting was created for human environments.

24 Relative Luminous Power - Natural Daylight at noon (D65)

25 Relative Luminous Power - Daylight at Sunset

26 Relative Luminous Power - Incandescent Lamp 2800K

27 Relative Luminous Power - Standard CFL 4000K (typical)

28 Relative Luminous Power – HPS lamp (typical)

29 Relative Luminous Power – High End LED 5400K (typical)

30 Relative Luminous Power - AgriShift™ PLWR5000

31 Dim To Blue - AgriShift™ PLWB5000 dimmed to 40%

32 Dim To Red - AgriShift™ PLWR5000 dimmed to 40%

34 Our Latest PL design

35 Energy Savings Example
56 lamp house 75W Incandescent Brood and Grow-out 52 day bird, typical lighting program Replace with AgriShift 12W PL lamp 1:1 screw-in replacement Save $1284 per year at $0.10/kWhr rate

36 Where do I place these? Indoors in hot, humid, dusty, damp, ammonia environments These lamps were designed for poultry, and built for the barn, not your kitchen. Kitchen lamps were not built for the barn In existing sockets in existing layouts that have up to 100W incandescent and/or 26W CFL lamps In the same layout you would use in new construction Dim-to-Blue lamps for Broilers, Hogs Dim-to-Red lamps for Breeder/Layers

37 AgriShift® EL Total power: 3W Equivalence: 20W incandescent

38 EL Body Style Options Designed to be placed in/on cage systems
Inside or across aisles Replace rope lighting, 20W Incandescent, 9-13W CFL

39 Decision Time for Poultry Farmers
Federal Law increases efficacy standards for incandescent lamps by 30%, effectively bans them 100W – January 1, 2012 75W – January 1, 2013 60W, 40W – January 1, 2014 They will have to make a choice – LED or CFL CFL lower cost, but underwhelming performance Mercury in CFLs can create food safety concerns Substantial increase in mercury waste

40 Incandescent Lamps Benefits Drawbacks Lowest Initial Price Dimmable
Understood by all No mercury in product Mercury released through coal-based generation Least Efficient High Energy Usage Highest Total Cost Short Lifespan Susceptible to vibrations A ban on standard 100, 75, 60, and 40W lamps begins phase-in Jan 1, 2012

41 Compact Fluorescent Lamps
Benefits Drawbacks Compared to incandescent Longer Life More efficient Less Energy usage Uses same socket Compared to LED Lower initial cost 10X-20X Price of incandescent Contains mercury Color Rendering Color Temperature Dimmability Fragile Susceptible to heat and vibration Cold Cathode similar issues

42 LEDs Benefits Drawbacks “New” Technology Highest initial cost
No Mercury Lowest Total Cost Low Energy Usage, High Efficacy Smooth dimming to 1% Longest life expectancy Sturdy, no filaments Instant on, no funny colors during warm-up On/Off Cycling and Dimming do not affect life “New” Technology Highest initial cost Many want to “wait and see” Many low-end, low-quality products

43 Efficacy vs. Efficiency
Efficacy – Lumens/Watt Efficiency - % Temperature Phosphors Light Source Ballast Losses Driver Losses Control Losses Wiring Losses “Benchtop” or die-level data does not tell the entire story

44 Real world applications
