The invention discloses an optical main body system for combining light paths, which comprises an optical main body seat, distance measuring modules and a light path adjusting module, the distance measuring modules at least comprise a first distance measuring module and a second distance measuring module, the first distance measuring module comprises a first generating unit for generating a first light beam and a first emitting unit for emitting the first light beam, and the second distance measuring module comprises a second emitting unit for emitting the second light beam; the second distance measuring module comprises a second generating unit for generating a second light beam and a second emitting unit for emitting the second light beam; the light path adjusting module comprises a merging unit and a plurality of reflection units, the reflection units comprise a first reflection unit used for reflecting a first light beam to a preset path and a second reflection unit used for reflecting a second light beam to the preset path, and the merging unit is arranged on the preset path; and configured to transmit the first light beam while reflecting the second light beam to combine the first light beam and the second light beam. According to the present disclosure, it is possible to provide an optical body system that optimizes the structural size of a coordinate measuring instrument and simplifies the optical path structure.

The invention discloses a lighting lamp which comprises a first light source set, a first reflection cup corresponding to the first light source set, a second light source set, a shading piece and a lens unit. The lens unit comprises a first subarea located in the middle and second subareas located on the two sides, and the first subarea and the second subareas have different focuses; light emitted by the first reflection cup is projected to the first subarea, and light emitted by the second light source group is projected to the second subarea. The lens unit has the first subarea in the middle and the second subareas located on the two sides, and light rays emitted by the first light source set are projected to the first subarea, light rays emitted by the second light source set are projected to the second subareas, so that the utilization rate of the lens unit can be greatly increased; and besides, the first light source set and the second light source set are controlled to be turned on and turned off through the control switch, so that switching between high-beam illumination and low-beam illumination is achieved, and the problems that energy is consumed and a machine is prone to being stuck when a traditional mechanical light changing mechanism is adopted are solved.

The invention discloses a lens module and a and lighting lamp. The lens module comprises a first light distribution body and a second light distribution body, wherein the first light distribution body comprises a plurality of first lenses, and the second light distribution body comprises a plurality of second lenses; an included angle between the main optical axis of the first lens and the main optical axis of the second lens is 80-100 degrees; according to the lens module, light spots can be projected on a fast lane and a slow lane at the same time through combination of the first light distribution body and the second light distribution body, the illumination area of a road is increased, and the road illumination effect is improved; meanwhile, the existing street lamp lenses are combined to form the lens module, and the lens module can be assembled with the existing lamp, so standardization and large scale can be conveniently realized, and mounting efficiency is improved; the lighting requirement in the width direction of a road is met through the lens module of the lamp on the single side, and the design, manufacturing and construction cost is reduced.
