Confident in Your Lighting Design?

Are design assumptions
grounded in reality?

Are my design assumptions
Is the suppliers’ information
consistent?
“Don’t worry – it will be fine”!

Are my design assumptions
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 lenses
form 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

NIDS Output is 2.7X Brighter Than OTS Lens!
NIDS design results in brighter output spot!
OTS
FWHM = 11.3 deg
NIDS
FWHM = 6.6 deg
NIDS output

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!
NIDS output
is 2.7 X
brighter than
OTS Lens
Hotspot
Hitting original photometric
spec requires 63% less drive
power

If it’s Brighter it can be Made Greener!
– No dice imaging
• Make it greener
– Reduce input power to achieve same CBCP
– Batteries last longer

NIDS Output – Brighter and Greener!
NIDS design results in product options!
NIDS output
is 2.7 X
brighter than
OTS Lens
Hotspot
Operate in intermediate
range to be greener
and brighter!

Have Your Cake and Eat it Too!
– No dice imaging
• 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”

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 power
Where 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!
Take advantage of the designs Avnet offers!
