The Importance of LED Color Consistency

Due to this reason, LED manufacturers are developing various patented binning optimization methods for best color consistency. High-power LEDs optimize processes to accurately control color variations. Some LED manufacturers use advanced container selection formulas that exceed the chromatic industry standards to ensure the uniformity and uniformity of color temperature and color tones.

The CCT temperature refers to the blackbody radiation. This is the light emitted by a solid object heated by the lamp. CCT is expressed in degrees Kelvin, which is the standard temperature measurement. The light emitted by a black body as it warms passes through a specific color line that follows a curve within a scene. Starting from red, the light changes to orange, yellow, white and blue.

For example, the color of the light emitted by a filament lamp, approximately 2700K. This value is at the end of the red or hot scale. The visible light spectral analysis makes it possible to define color temperatures for non-glowing white light sources, such as LED lighting and fluorescent lamps. Although the LED gives the same light color as a heated 2700 K wire, it has a real temperature of approx. 80 degrees.

The tolerance or range of variation corresponds to each curved and curved CCT. Changes in curiosity cause blurredness of the light source or red, and these variations make the curve of the upper and lower black body pink or green. These changes are measured along the curve of the black body at Calvin, and the curve of the vertical fluctuations is called Douv. The CCT types allowed at each color temperature in the color scale are defined by square, vertical and curved lengths. The duv and CCT intervals indicate each type of four pages for each color temperature.

LEDs vary in lumen, CCT and voltage during the production process. Because these differences may be significant, LEDs are marketed on discs. This connector process allows the selection of LEDs that meet the specified specifications. For example, binning lets you select LEDs that meet the US standard when it comes to the specific color required.
Lighthouse manufacturers are developing different methods for selecting LEDs in a way that minimizes color differences, which can be seen from production to production or from the luminaire to the luminaire.

Some LED manufacturers have 16 boxes for a nominal value of 2700 K. However, there will always be a specific variation of Duv fluctuation and K-degree from bucket to bucket. To ensure the consistency of the colors, some manufacturers of LED luminaires want to exceed the standard by introducing standards for LED packaging. For example, Gerolux has developed a mathematical classification model called Ledybin. This mathematical model guarantees the uniformity of color in all production lines for all LED strips.
Instead of following the lack of 7 steps of the ANSI standard, the LED lighthouses and CCAd Ledybins from MacAdam are elliptical in 4 steps. Ledybin will use the discs' LEDs as close to the basket as possible to avoid color changes.

Within a 4-step MacAdam ellipse, there are 4 bins. However, for the production run to the production run, only one container is used, so the consistency is always within 2 SDCM per stack and per roll.
