DATA_OVERVIEW:
- The database combines two public LED spectral datasets.
- Common wavelength grid: 350 nm to 830 nm.
- Common sampling interval: 5 nm.
- Dataset A original sampling interval: 1 nm.
- Dataset A is sampled every 5 nm on this page.
- No interpolation or smoothing is applied to Dataset A.
- Dataset A original coverage: 360 nm to 830 nm.
- Dataset B coverage: 350 nm to 780 nm.
- Some Dataset B records cover only up to 750 nm.
- Spectral values are relative SPD values.
- Each spectrum is normalized to its own peak.
- Relative SPD is NOT absolute radiant power.
- Do not infer absolute optical output power,
irradiance, PAR or efficiency from normalized SPD.
DATASET_SOURCE:
Dataset A:
- References EMPIR 15SIB07 PhotoLED Database
of LED Product Spectra, Version 2.
- Associated with the Technical University of Denmark (DTU).
- DOI: 10.11583/DTU.12783389
- Source license: CC BY 4.0.
- Original 1 nm sampling is reduced to 5 nm sampling
on this page by selecting every 5 nm point.
- No interpolation or smoothing is applied.
Dataset B:
- A second public LED spectral dataset.
- Do not assume Dataset A license applies to Dataset B.
- Check Dataset B original source for its license and attribution.

APPLICATION_FEATURES:
- Search by spectrum ID and label.
- Filter by dataset and source type.
- Filter by spectrum class and peak wavelength.
- Filter by CCT and Ra when available.
- View individual spectrum curves.
- Compare up to 6 spectra.
- Mix up to 8 monochromatic wavelengths.
- Overlay sunlight reference curve.
- Export filtered results as CSV.
- Export selected spectrum data as CSV.
- Export comparison data as CSV.
- Export monochromatic mixture data as CSV.
SPECTRUM_CLASSIFICATION:
- Classification is inferred from spectral shape on this page.
- Single-color / narrowband:
single narrow peak.
- Blue-dominant:
peak below 500 nm and more than half of energy
in the 400-500 nm range.
- Yellow-green, yellow-orange and red-orange broadband:
blue-pumped phosphor white-light spectral shapes,
classified by phosphor broadband peak position.
- Low-blue:
no obvious blue peak.
- Classification is a page-level derived category,
not necessarily a manufacturer-provided label.
SYNTHETIC_EXAMPLE_CURVES:
- Standard monochromatic LED example curves:
40 examples.
- Additional blue narrowband spectra:
7 examples.
- Standard monochromatic example curve shapes are generated
by shifting a template curve.
- These are NOT individual LED measurements.
- Do not describe each standard monochromatic example
as a separately measured physical LED spectrum.
SUNLIGHT_REFERENCE_LIMITATION:
- The original wavelength axis of the sunlight overlay
has not been confirmed.
- The sunlight overlay is for spectral-shape comparison only.
- Do not treat it as a verified calibrated measurement
or use it for quantitative wavelength calculations.
IMPORTANT_INTERPRETATION_RULES:
- CCT, Ra, Rf and R9 are provided only for Dataset A.
- CCT uses the CIE minimum Duv method.
- Records with absolute Duv greater than 0.05
are not displayed with CCT.
- Single-color spectra do not have ordinary white-light
color rendering index meaning; display as unavailable.
- Do not invent missing metadata.
- Do not treat missing spectral values outside a recorded
range as proof of zero emission.
- Do not compare absolute output between spectra
using peak-normalized relative SPD.
- The database does not display luminaire brand or model.
- Distinguish source-provided facts from calculated,
inferred, template-generated or illustrative data.
- The relational schema above is a recommended logical model,
not confirmation of the current production backend schema.
AI_USAGE_GUIDANCE:
When answering questions about this database:
1. Identify whether information comes from Dataset A,
Dataset B, a derived category or an example curve.
2. Identify whether a value is source-provided,
calculated, inferred or template-generated.
3. Preserve wavelength units in nm.
4. Preserve relative SPD normalization context.
5. Never claim absolute radiant power from relative SPD data.
6. Do not fabricate missing CCT, Ra, Rf or R9 values.
7. Do not describe template-shifted monochromatic examples
as individual measured LED spectra.
8. Treat sunlight overlay as shape reference only.
9. Do not assume Dataset A license applies to Dataset B.
10. Refer users to the official page for interactive inspection
and CSV export.
