Optical emission assembly and optical module

An optical emission assembly, comprising:

• a body provided with a first positioning groove, a second positioning groove, an accommodation groove and a through hole, one end of the accommodation groove communicating with the first positioning groove and the second positioning groove respectively, the other end of the accommodation groove communicating with the through hole, and a groove bottom of the first positioning groove communicating with a groove bottom of the second positioning groove;
• an adapter connected to an outer surface of the body and comprising an optical fiber ferrule, and the optical fiber ferrule being disposed corresponding to the through hole;
• a first light-emitting assembly comprising a first heat-conducting base and N first light-emitting chips disposed on the first heat-conducting base, N being a positive integer, wherein when the first light-emitting assembly is installed in the first positioning groove, a surface of the first heat-conducting base provided with the N first light-emitting chips faces the groove bottom of the first positioning groove, and the N first light-emitting chips are configured to emit light beams toward the accommodation groove;
• a second light-emitting assembly comprising a second heat-conducting base and M second light-emitting chips disposed on the second heat-conducting base, M being a positive integer, wherein when the second light-emitting assembly is installed in the second positioning groove, a surface of the second heat-conducting based provided with the M second light-emitting chips faces the groove bottom of the second positioning groove, and the M second light-emitting chips are configured to emit light beams toward the accommodation groove;
• a multiplexer disposed at a bottom of the accommodation groove and configured to combine the light beams emitted by the N first light-emitting chips and the M second light-emitting chips into one light beam;
• and
• a converging lens disposed in the through hole and configured to converge the one light beam emitted from the multiplexer to the optical fiber ferrule.
