Zusammenfassung: | The invention discloses a low-light camera applied to a train early warning system, which belongs to the technical field of cameras and comprises a lens (1), a detector base (9) and a detector (8), the lens (1) and the detector base (9) are fixedly mounted in a lens cone, and the detector (8) is mounted above the detector base (9). The device further comprises a lens conversion ring (3) fixedly arranged between the lens (1) and the detector (8), the lens conversion ring (3) comprises a coil (2), a magnetic bead (5) matched with the coil (2) and a switching mechanism (4) fixed below the magnetic bead (5), and the switching mechanism (4) comprises a compensation sheet (6) and an attenuation sheet (7). Therefore, clear imaging in the daytime, clear imaging in a field low-light environment without lamplight, distance measurement and urban environment imaging with more lamplight at night are realized.
