The invention relates to the technical field of reflective condensation structures and provides a reflective condensation structure of an illuminating lamp. The reflective condensation structure comprises a fixing structure, a universal shaft is fixedly mounted on one side of the outer surface of the fixing structure, a connection seat is rotationally connected to the fixing structure through theuniversal shaft, an outer shell is fixedly mounted on one side of the outer surface of the connection seat, and a power structure is fixedly mounted in the outer shell. The inner wall of the power structure is provided with a slide groove, a light-permeable plate is slidably connected on the inner wall of the slide groove, and a lamp body is fixedly mounted in the outer shell and between the powerstructure and the light-permeable plate. By adjustment of an angle between reflector and a distance between the light-permeable plate and the lamp body, light of the lamp body and light reflected bythe reflectors are gathered through a high condensation plate to maximize the condensation degree of the lamp body, and a light beam is irradiated to a road surface by an anti-fog lens to further improve integral visibility in rainy and foggy days, so that people can feel safe and relieved in driving.
