Advanced spectrum LED typically utilizes violet or dual-blue chips to excite a combination of phosphors (red, green, blue), resulting in a continuous spectrum that closely mimics natural sunlight. Compared to conventional white LEDs—which generally use blue chips to excite yellow phosphor—advanced spectrum LED emits more evenly across the 400–780 nm range, reducing the issue of excessive blue light peaks.
High Color Rendering Index (CRI)
Advanced spectrum LED has a CRI greater than 90, with top-tier products reaching 97–99, closely replicating natural light in terms of color rendering ability.
High Color Fidelity and Gamut (Rf and Rg)
In high-end display and professional lighting applications, full-spectrum LEDs allow for more accurate and vivid color reproduction of objects.
Reduced Blue Light Hazard
By optimizing the spectral distribution and minimizing the intensity in the 460–490 nm range, advanced spectrum LED helps protect eyesight.
Supports Human-Centric Lighting
Advanced spectrum LED can be tuned in terms of color temperature and spectral composition, helping to promote alertness during the day and relaxation at night.
High Luminous Efficacy and Energy Efficiency
Although adding more phosphor may slightly compromise luminous efficacy, modern advanced spectrum LED technology can still achieve 120–180 lm/W.
Violet Light Exciting RGB Phosphors: This approach enables a smooth, continuous spectrum with no significant dips.
Dual-Blue Excitation Technology: By using two different blue wavelengths, the spectral coverage of the LED is improved.
Multi-Channel Color Mixing: Combines monochromatic LEDs (red, green, blue, etc.) to dynamically adjust light output and color.
Perovskite and Quantum Dot Materials: Used in the development of more efficient and broader-spectrum light sources for advanced spectrum LED.
