[0002] The LED packaging components mainly include substrates (heat dissipation), packaging glue (silicone), packaging lenses (with high refractive index and light transmittance), etc. The cooperation of the packaging glue and the packaging lens not only provides protection for the chip (to prevent the chip from being exposed to air for a long time or being mechanically damaged to fail, so as to improve the stability of the chip), but also achieves good light output efficiency, thereby making the LED have better light emitting efficiency. The LED chip packaging technology usually installs the LED chip on the PCB and uses the packaging glue to seal, so as to protect the LED chip from the external environment. Although this packaging technology works well in many cases, there are still some limitations, one of which is the problem of the divergence angle of the LED chip.

Chinese Patent No. CN102255035A discloses a substrate multi-LED chip packaging structure. In this patent, a silicone ball lens is arranged above the upper layer of the plane silicone glue and the LED chip in the existing COB light source. The light rays that are greater than the critical angle and are reflected by the plane silicone glue and air are guided out of the air, thereby improving the light output efficiency of the COB light source.
