LED Lighting OEM “Pain Points”

Slow Product Development

Cycles

Not able to custumize special

products fast

Struggling to keep pace with fast LEDs

improvements

Frequent Write-Offs

Significant financial drag from high

inventories

High volume driven


Pace of the Industry

LED Technology offers great potential:

Lighting Industry must adapt to velocity of semiconductor technology cycle

• Industry Participants have to strive to keep up with the (r)evolution of the LED technology

Such a (r)evolution demand Lighting OEMS to change!

• Get prepared to keep up with the pace + to write black figures

Or…. get left behind!


Lighting (Industry) of Today


Back to the Basics of Lighting

Light up a place

Accentuate an object

Improve sales of products

Create Atmosphere

Create safety

Growth of products


How People experience the Lighting Industry

•“At almost every booth I see the same Me2-products!”

VC Executive

•“This industry is focussed on Price/Lumens/Watt -Ratio instead of delivering light where it is required! They use all quite the same components + designs”

Lighting Architect

•“If Lighting OEMs can’t spezialize their offering we end with a few big companies + specialists in Lighting Industry ”

Plastics Supplier

Printed Optics for LED Lighting


OEM Benefits

• Development costs . Products late to market . Number of new products tested . Revenues . Profits

Faster Product Introductions

• Revenues . Market Share . Reputation . Product Margins . Profits

Profitably Serve High Margin Custom Optic Markets

• Price Premium . Revenues . Market Share . Reputation . Product Margins . Profits

Fast Product Upgrades to Latest LED modules

• Working Capital . Impaired Inventory Write Offs . Profits

Reduced inventories

• Cost for LED modules . Product out of stock . Product out of spec due to “forced” substitution of LED color bins . Profits

LED module flexibility = Purchasing Power

• Out of Stock . Revenues . Working capital . Profits .“Just In Time” Production


Designer Benefits

• Complexity is free with digital printing (freeforms)New optical + fixture designs possibilities

• Prototyping identical as manufacturing Rapid Prototyping + Testing

• 1, 10, 100, 1000, 100000 pcs. all possible On DemandSmall Volumes

Printed Optics Enables Radically Better Fixture Design

Groom Energy Report on Lightfair 2012:

“It’s no longer about the chip, but about the fixture design”.

http://blog.groomenergy.com/2012/05/lightfair-2012-has-led-lighting-supplanted-everything-else/


New Freeform Optics

(1) Freeform Fresnel optic design published by researcher in 2011 academic article. Never been manufactured due to cost / infeasibility of tooling.

(2) Optic printed by LUXeXceL directly from the researcher’s CAD file


Even Rectangle Illumination Configurator

Some Parameters: Light source? Lit centrally or from the edge? Target square or rectangular?

Example light distribution patterns for EVEN, SMOOTH, RECTANGULAR illumination.

Example Freeform lens design to deliver these goals

With Printoptical “Complexity is free” – these lenses can readily be printed!


First Prototype Square Illumination Optics

• Optics create a square beam from a previous round beam fixture;

• First “proof-of-concept” – significant potential for further improvement;

• Printoptical process allowed rapid prototyping and physical validation, to enable an rapid iteration process;

Original Beam Wide Square Beam

Narrow Square Beam Special Effects Beam


First Prototypes TIR Printed Optics

• Proof-of-concept “Lab Prototypes” of TIR optics• TIR = Total Internal Reflection – a common design

used for plastic molded optics to replace metalized reflectors

• Optics shown here are 15-20 mm tall, typical size for TIR. This shows the potential to make optics much taller than the current 2-3mm depth currently offered for production


Hurdles of AM in Lighting Industry

Lots of Additive Manufacturing Equipment Manufacturers, Material Suppliers, Software Creators are working at speed to help you to enjoy the advantages of a new digital era to:

1. Become more flexible 2. Become faster3. Offer customization options4. New online-optics design possibilities5. Become more Profitable
