Deep red and near-infrared are important wavelengths for specific applications as horticulture lighting, medical lighting and relevant device or instrument. However there is only the semiconductor red or near-infrared LED in the general market with single bands of typical peak wavelengths of 630nm, 660nm or 730nm. With remarkable phosphor and LED packaging technologies, Yujileds releases a new 3030 LED with longer-wavelengths enhanced features.
This mid-power LED is designed with Yujileds phosphor solutions for imporving deep red and near-infrared spectrum. In the range of 600nm – 800nm, it extends nearly 50% of the relative spectral power distribution than a standard LED.
For the CCT 6500K, the spectral power is uniformly distributed at the full wavelength without obvious gaps. By achieving 90 CRI, this LED is also friendly to human eyes.

This LED is designed with two LED chips of 370nm and 400nm, exciting six different phosphors including the latest two near-infrared phosphors. According to the fundamental of phosphor excitation and emission and the Stokes shift, figure 4 introduces the basic principle of the resultant spectrum and figure 5 shows the actual spectrum combinations.
With the shortest wavelength of 370nm chip and the longest wavelength of 800nm phosphor, this full spectrum achieves the coverage from 350nm to 1000nm, which is also the limitation of the test range for general spectrometers. Besides the two peaks of the chip, the spectrum at different wavelengths is distributed evenly with typical 20% relative intensities. The spectral power distribution can be observed more clearly with the logarithmic axis.
One of the main technical breakthroughs of this spectrum is the near-infrared phosphors. The radiant power of current infrared phosphors on the market is weak, discrete and generally can only be observed when converting the axis from standard to logarithmic. For this new full-spectrum, there is no gap between 660nm and 1000nm and the infrared part is as strong as the visual wavelength.

This hyperspectral LED is designed and considered for non-visual and non-human-centric purpose, the potential biological risk due to the spectral content of UV is reminded and emphasized here. Users should well understand the risk and take appropriate protections when applying this LED.
