YUJILEDS® Ultra Broadband (350 nm – 1000 nm) LED SMD

YUJILEDS® Ultra Broadband (350 nm – 1000 nm) LED SMD

One of the retards of using LEDs to replace traditional light sources is the discrete spectrum of LED chips. Fields like spectrometry that require a continuous spectrum extended from UV to IR have to keep on Xeon lamps and cannot be benefit from LEDs’ long life-time, high luminous efficacy and stability. However, with the effort of YUJILEDS® to pursuit high quality LED spectrum, the ultra broad band spectrum (350 nm – 1000 nm) LED compacted in one package will solve this problem.

This LED is sealed in a 2835 package with two chips of 370nm and 400 nm, exciting 6 different phosphors including the latest two kinds of near-infrared phosphors. Figure 1 shows the principles of how to get the resultant spectrum.

With the help of UV LED chip and IR phosphor, the spectrum could reach wavelength shortest to 350nm and 1000nm on the other side, with a flat curve thanks to the breakthrough of the near-infrared phosphor technology of YUJILEDS®. As a comparison, phosphor based IR LEDs on current market has power lower to 0.1% compared to a visible LED. With no gaps in the visible and infrared range, it is best for most sensing applications like spectrometry.
