  • What causes LEDs to deteriorate in brightness or output?
    Apr 23, 2018

    Typically, when current flow within a LED junction is not uniform, small temperature differentials occur within the chip. This exerts stress on the lattice, causing minute cracks to occur. In time, this accumulation of defects reduces the photon conversion efficiency of the chip, thus reducing light output. This rate is influence by various factors including LED material, temperature, humidity, and current flow.
