Chips 4 Light offers LED chip typing by dominant, peak or centroid wavelength – optionally specified in mW for precise OEM and laboratory requirements
Precise Wavelength Typing for LED Chips – Flexible Spectral Binning for Sensor and Measurement Applications
Many lighting applications work with the dominant wavelength (lambda dom) as standard. However, in numerous technical applications – even in the visible spectral range – this variable is not ideally suited.
Especially in sensory applications, the exact spectral characteristics are particularly important. Here, grouping according to peak wavelength or centroid wavelength is often much more meaningful and closer to the application.
Our offer: Precise typing – tailored to your application.
Chips 4 Light GmbH is one of the few suppliers to offer you the option of flexibly typing LED chips according to various wavelength parameters:
- Lambda dom according to classic color standard
- Lambda peak
- Lambda centroid
- Optionally also in mW instead of lumens
These options are rare in the industry and represent clear added value – especially for OEMs, laboratory applications, measurement technology, and sensor systems.
Definitions:
The dominant wavelength is a colorimetric term. It describes the wavelength of monochromatic (single-color) light that would have the same perceived color as the given light source.
The peak wavelength is the wavelength at which the spectral distribution of a light source spectrum reaches its maximum—in other words, the point at which the light source emits most strongly.
The centroid wavelength is the intensity-weighted average of the wavelengths – i.e., the “center of gravity” of the spectrum.
