What is LED binning?

If you want to switch to LEDs and search for the right product, you should know the term binning. But what is binning? In the industrial production of LEDs, there are always deviations: even LEDs of the same product batch differ in their properties. In order to avoid large deviations, those with similar performance are combined in so-called "bins" (containers). Especially with LEDs with white light spectrum binning is absolutely necessary, since color temperature and brightness values ​​can otherwise vary too much.

Key facts at a glance:


·        Binning areas sort LEDs for similar power
·        Luminosity and color temperature are the most important binning criteria
·        ANSI LED binning standards to mark deviations in specific areas
·        Deviations are indicated by the unit SDCM
·        Color temperatures can also deviate independently of binning, e.g. due to age or due to wear of light sources

Binning

Why is LED binning important to you as a consumer? The answer is simple: binning systems ensure lighting standards of LEDs. This ensures that the same LEDs deliver the same performance - and you will not be disappointed with products. Most manufacturers sort their products into the following binning ranges:
·        Luminosity (lumens )
·        Color temperature (Kelvin)
·        Voltage (volts)
·        Color location (color impression when viewed directly)
To which bin a product class has been assigned, the manufacturer usually states on the datasheet. It's worth taking a look - this is how you find out about the assigned properties of the LEDs.

Luminosity and color temperature is the most important binning criteria that directly affect the product performance of LED chips. For example, to sort the LEDs by luminosity, they are individually measured and sorted into predetermined ranges. Manufacturers tend to develop their own binning system that fits the production results. The larger the bin, the more the values ​​of the individual LEDs may differ. The closer the bins are set, the more expensive the sorting and accordingly the LED product.

ANSI LED binning standards


To ensure that LEDs have the same color temperature, they are sorted according to the ANSI (American National Standards Institute) standard. It defines chromatic aberrations using the Macadam ellipses, also known as Standard Deviation Color Matching.
The ANSI the standard recommends that the color value is within four thresholds in an ellipse. The ellipses inform the user about how far apart, for example, the light color of individual LED chips from each other. LEDs in these bin areas guarantee uniform light colors, for example, that 4,000 K is cool white. Most manufacturers use an average of 2 SDCM.

This table should clarify the system: 

McAdam Ellipses (SDCM)
visibility
1 SDCM
Almost impossible to see a difference
2 SDCM
Differences can be seen through gauges
3 SDCM
Fewer color differences visible
4 SDCM
Color differences are visible
5 SDCM
Distinct differences are visible



Interesting to know


In the past, the reference positions of the MacAdam ellipses were arbitrary and did not cover all color ranges. At temperatures above 6,000 K, no MacAdam ellipse was assignable unless the manufacturers defined their own. Fortunately, this has changed today.

 Further deviations of the color temperature

·        Manufacturing tolerances ensure that the same products do not produce a different color impression
·        After 10,000 hours, there may still be an age-related color shift
·        The V before Using devices and covers will represent the original color temperature wrong
·        In order to avoid large deviations, LEDs in terms of technology and quality will be made more precise in the future.

What are highbays used for?

Indoor floodlights or so-called LED HIGH BAY LIGHTS are used in department stores or factory buildings because the light is as bright as daylight and this promotes productivity and safety. We recommend that you use high bay with LED technology to save additional energy and thus money. Key facts at a glance: ·         Adequate lighting in warehouses is especially important for safety ·         High bays are mostly used in daylight white (> 6,500 K) to simulate daylight within a hall ·         LED high bays are longer lasting, more energy efficient and contain no toxic substances such as B. in HPS lights, in which mercury is included ·         Protection to IP65 or IP66 should be given What are the problems with lighting large interiors? In order to illuminate effectively and safely, it is important that department stores, ...

Return on investment through LED

Image
LEDs are more expensive to buy than conventional bulbs, but then you save a lot of money afterward. Because light sources that use modern LED technology consume many times less energy. As a result, you achieve a quick amortization of the purchase price. And the replacement costs are due to the long life of LEDs vanishingly small. Key facts at a glance: ·         LEDs are more expensive to buy ·         But: much lower energy consumption = less running costs ·         Thereby fast amortization ·         Long life minimizes replacement costs ·         Little to no maintenance necessary ·         LEDs save you money in the long term and protect the environment When switching to LED, many customers are deterred by the higher purchase price. Modern LEDs are more...
