XINGLIGHT's top light-emitting series lamp bead is a kind of patch light-emitting diode (LED), and its light-emitting area is located at the top of the lamp bead. This unique structural design enables the light to directly emit from the top, which has higher light output efficiency and more concentrated light emitting direction compared with some side light emitting or other structural lamp beads. It usually adopts special packaging materials and processes to package the chip in a small shell to protect the chip and achieve good electrical connection and optical performance.
