1. Basic Things to Know about LED Lamps
Performance is the result of 3 groups of components
Optical LED components
perceived to deliver the same or better light effect as the original light source (beam shape, intensity, color point, color rendering),
and perceived as equal or better light quality - variation between lamps
Electrical LED components need to be 100% compatible with the electrical input power characteristics and 100% compatible with installed accessories (dimmers, transformers), while causing no non-compliances.
Mechanical & thermal LED components mechanical compatibility (shape, size) into an existing socket & fixture and thermal compatibility into existing socket & fixture

Binning is the technique for sorting LED’s for consistency.
Single bin LED’s are both expensive and hard to get.
Strategies for good color consistency:
Tight binning from the LED manufacturer (cost and logistical issues)
Binning at the luminaire manufacturer (ColorKinetics has technology for this)
Mixing within the luminaire
Remote phosphor technology (next slide)
CIE Chromaticity Diagram
Each color consists of several different “bins”
The performance of each LED is unique
Each LED is binned by three measurements: output color
power

3. Binning All LED Components In A Product Batch Are Different
Manufacturing
Inspection & QC
Sorting a.k.a. Binning
Higher output bins cost more
Bins closer to the black body curve (“whiter”) cost more
Manufacturers will not sell you just one bin in large volumes
Manufacturers will not guarantee availability of specific bins
Cool
Warm
High Output
Low Output 3

4. Light Quality LEDs and Standards
Methods for Achieving Good Quality Light
Use only one LED bin
LED Binning Algorithms
Optical treatments to reduce variation
Fixture Calibration

5. Light Quality LEDs and Standards
Conforms to ANSI C78.377A

6. Light Quality Philips LEDs
Philips Optibin’s CCT and hue tolerances for LED’s fall within a 4-step
MacAdam ellipse , rather than 7-step ellipse defined by ANSI standard
Optibin dictates the use of LED’s from bins which lie close as possible
to the black-body curve within the 4-step ellipse. This proprietary algorithm
intelligently combines LED’s from different bins, guaranteeing color
uniformity for lamps purchased and shipped at different times
SDCM – Standard Deviation of Color Matching
A color difference of 1 SDCM “step” is not visible
2 – 4 “steps” is barely visible
5+ readily noticeable 6

7. This is a Philips Exclusive
Color Consistency Across Fixtures Binning Combined With Software Logarithms Improves Consistency
This is a Philips Exclusive
Optibin®
LED Manufacturer
LED manufacturers group output into bins
Higher output bins cost more
Bins closer to the black body curve (“whiter”) cost more
Manufacturers will not sell you just one bin in large volumes
Manufacturers will not guarantee availability of specific bins
Optibin ® is a proprietary mathematical model that tells manufacturing which LEDs to place in which locations
Allows us to buy a wider selection of bins
Allows us to control fixture color and output performance
