Hyperspectral LED with 350nm-1000nm coverage
This LED is applied in a 2835 package with two LED chips of 370nm and 400nm, exciting 6 different phosphors including the latest near-infrared 1 and near-infrared 2 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.
Full wavelength coverage
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.
Enhanced infrared radiance
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.
