Confident in Your Lighting Design?



Are design assumptions grounded in reality?



Are my design assumptions grounded in reality?

Is the suppliers’ information consistent?

Is my suppliers’ information consistent?

“Don’t worry – it will be fine”!

How robust is my design to manufacturing tolerances?


Illumineers Provide the Difference!• Pre-sales lighting design support for our customers

– Lab caliber specialty– Quickly prototype/evaluate luminaires in design software

Generate IES files for analysis in lighting packages


Imaging Lens Design

Primary Difference - Design for Lighting

The “parabolic” solutions used in lighting today were originally designed to form images

Galileo and his refracting telescope Newton and his reflecting telescope

Camera lensesform images for pictures


Imaging Design Curves Not Best for Lighting

State of the Art Lighting!


Illumineers Use NIDS for Lighting Design

• NIDS = Non – Imaging Design System

• Very fast and versatile

• Provides superior design results for lighting applications when used with real world data!


NIDS in the Real World – LED Rayfiles

Gonio-Luminance measurements

for accurate ray data files

LED mounted on center post

Camera takes ~ 2,000 measurements over whole

hemisphere

Luminance measurements of LED sources produces rayfile data for

accurate simulation work

No dice imaging!


NIDS Output is 2.7X Brighter Than OTS Lens!

NIDS design results in brighter output spot!

OTSFWHM = 11.3 deg

NIDSFWHM = 6.6 deg

NIDS output is 2.7 X

brighter than OTS Lens

Critical Brightness Advantage

• Illumineers make your products brighter– Beat out traditional designs!– Spot luminaire can be almost 3x brighter!– No dice imaging


NIDS Output – a Greener Alternative!

NIDS design can provide same brightness for less power!




Hotspot

Hitting original photometric spec requires 63% less drive

power


If it’s Brighter it can be Made Greener!


• Make it greener– Reduce input power to achieve same CBCP– Batteries last longer


NIDS Output – Brighter and Greener!

NIDS design results in product options!




Hotspot

Operate in intermediate range to be greener

and brighter!


Have Your Cake and Eat it Too!


• Make it greener– Reduce input power to achieve same CBCP– Batteries last longer

• Make it brighter and greener– Best of both worlds– Design for both to differentiate your product!


NIDS Offers Design Versatility and Value!How did you get those

lights so bright!?I called those Avnet guys

Illumineers satisfy the toughest customers!


Cove Lighting Example – Need More Physics

Mid or Low Power Linear Array of LEDs Inserted Into Extrusion

Reflected and Transmitted Scatter will be Significant


• Real world materials can be characterized– Reflection = BRDF– Transmission = BTDF

• These functions can be loaded into optical design packages

• NIDs designs based on these files yield highly accurate results!

Reflection and Diffusion in the Real World


The extruded reflector pictured above was optimized to “collimate” vertical light output

Cove Lighting Example – Reflector Extrusion

Use reflector to make vertical rays “tighter”

Horizontal

Vertical

Angled view shows LEDs at base of extruded reflector 1” deep

Horizontal

Angled view shows LED array at base of extruded reflector 1” deep

NIDS Extrusion - 6 X 110 Deg Output!

• 110 deg beam angle for the horizontal output is essentially Lambertian

• 6 deg beam angle for vertical distribution is extremely tight

• Used by itself or as the base unit for use with diffusers to produce a series of cove lights


20 Deg Diffuser (BTDF) Widens Vertical O/P

False color LI of 20 deg Surface Diffuser Over Reflector

False color chart shows vertically compressed but brighter output

The output LI distribution changes from a severe 6 X 110 degs to a smoother 40 X 84 deg


The Main Takeaway - A Brighter Design!

Caution: Avnet lighting design in progress!

More powerWhere you want it!

Would your customer’s want brighter outputs?


A Greener Design!

Less power for the same

output?

Or optimized energy efficiency?

Lower carbon footprint

Green products


Or the Best of Both Worlds!

Find the sweet spot for your products!
