Knowledge Chromaticity (Color of Light) and CIE Chromaticity Diagrams
Chromaticity refers to the color of light. It's an objective specification of the quality of a color regardless of its luminance. In other words, chromaticity captures the hue and saturation of the light, ignoring light intensity—the third dimension of human vision. Hue is the perception of...- Shine

Knowledge What Causes Color Shifts in LED Lights?
Color stability refers to the ability of light sources to maintain their spectral power distribution (SPD) over time. While lumen maintenance is important for LED packages, the change in chromaticity—typically referred to as color shift—must not be overlooked. The term chromaticity refers to the...- Shine

Knowledge What Is LED Binning?
LED binning is a process of sorting LEDs according to specific criteria such as chromaticity, lumen output (luminous flux), and sometimes forward voltage (amount of voltage it takes to turn on an LED). Variability in the manufacturing process from wafer production and crystal growth to component...- Shine

Knowledge LED Lighting: What is Warm Dimming or Dim-to-Warm?
Warm dimming or dim-to-warm refers to the ability to reduce the color temperature of a light source in proportion to the intensity. Warm dimming is designed to mimic the color characteristics of incandescent lamps when dimmed. The color temperature of light emitted by an incandescent lamp at...- Shine

Knowledge How Stokes Shift Impacts LED Efficiency and Color Quality?
Phosphor conversion (PC) is the most widely used approach for generating white light with LEDs. The technique involves using a blue LED (InGaN chip) to pump light into a phosphor down-converter. A portion of short-wavelength photons is absorbed by phosphors and converted into longer wavelength...- Splendor
