Light Emitting Diode Led Three proof series 5050G
Phosphor sedimentation
When the Lamp Beads were assembled into LED lamps and stored in the warehouse, the color temperature drifting failure occurred. The packaging glue of the failed Led Lamp Beads changed from orange to light yellow. The IV characteristic test was carried out on the lamp beads Light Emitting Diode Lamp Beads. It was found that the lamp beads could light up normally and the IV curve Normal, but the brightness of the light has changed. Take some failed lamp beads and take out the encapsulant by mechanically unsealing. It is found that there are transparent particles on the surface of the bracket. SEM&EDS is used to test the composition of the particles, and the results show that they contain high content of strontium (Sr) element Straw Hat With Lamp Beads.
In contrast, after the good-quality lamp beads are opened, the surface of the bracket is relatively clean. The main components of the surface are silver (Ag) and a small amount of carbon (C). No strontium (Sr) element is detected. Strontium (Sr) and barium (Ba) elements were also not detected on the contact surface. By testing the cross-sectional composition of the failed product and the good lamp bead encapsulant, it is known that the phosphors used in the two have the same composition, and they are all yttrium aluminum garnet (the main components are oxygen (O), aluminum (Al) and yttrium (Y) ) And barium strontium silicate (the main components are carbon (C), oxygen (O), silicon (Si), strontium (Sr), barium (Ba) and calcium (Ca)) mixed phosphor High Power Lamp Beads 1W.
Therefore, the failure reason of the LED Lamp beads is that the used silicate phosphor settles to the bottom of the encapsulant and the surface of the bracket, resulting in dispersion due to inconsistent light refraction laws, resulting in color temperature drift and lamp beads discoloration Led Light String.
