The above-mentioned upper and lower positions refer to the relative positions among the reflector 320, the lamp cover 500 and the lamp source 330 in fig. 5, when the dome camera is normally installed, the lens assembly 400 generally has a downward component, in this case, the lamp cover 500 is located below the lamp source 330 and the reflector 320 is located above the lamp source 330 along the longitudinal direction, and the specific positional relationship may be determined according to the actual installation condition of the dome camera.

In the embodiment of the application, a camera with a focal length of 4mm is taken as an example, the field angle of the lens is 90 degrees horizontally and 50 degrees vertically, and the light supplement area needs to meet the field range. In order to obtain a good light compensation effect, the light reflected by the reflector 320 is distributed according to a rectangle rather than a conventional circle or ellipse, all the light emitted by the lamp source 330 can be distributed in the range of the lens field of view to the maximum, and all the light emitted by the lamp source 330 is irradiated onto the reflector 320.

In order to make the light supplement region satisfy the lens field range, the structure of the reflector 320, the optical path and the installation position of the reflector 320, and the like are designed in the embodiment of the present application, specifically as follows:

in an alternative embodiment, the reflector 320 includes a reflector, which may be a concave structure, a cross section of the reflector in the first direction (i.e., the longitudinal direction) is arc-shaped, an inner concave surface of the concave structure is a reflecting surface of the reflector, when the fill-in light source generated by the lamp source 330 irradiates on the reflecting surface, the reflecting surface reflects, a reflecting angle is affected by a specific size of the arc-shaped reflecting surface and a relative position between the lamp source 330 and the reflecting surface, and all light rays of the fill-in light source reflected by the reflecting surface are maximally distributed in the lens field.

Further, the light source 330 is disposed longitudinally above the reflecting surface, and the light source 330 is disposed at a position offset from the geometric center point of the reflecting surface.

Further, as shown in fig. 13 to 15, the reflection element 320 is a plate structure as a whole, and the reflection element 320 includes a reflector for reflecting the supplementary lighting source generated by the light source 330, where the reflector includes a first surface 321, a second surface 322, and an end surface 323, the first surface 321 and the second surface 322 form an inner concave space 324, the first surface 321 is connected to the second surface 322 through the end surface 323, specifically, the second surface 322 is away from the first surface 321, and since the first surface 321 and the second surface 322 are both arc-shaped in the longitudinal direction, the first surface 321 is located inside, so that the inner concave space 324 is formed on one side of the first surface 321, and the inside surface of the inner concave space 324 is a reflection surface, that is, the first surface 321 is a reflection surface.

Based on the above arrangement, through the light supplement lamp assemblies 300 on the left and right sides of the lens assembly 400, the emitted light supplement light sources can be spliced to form an integral light supplement area, and since the light supplement light plate edge cutoff of the light reflecting part is high, the light path of the reflector 320 needs to be accurately designed to ensure the ideal splicing of the light plates, so that the splicing light and dark area is avoided.

Referring to fig. 16 and 17, the light supplement light sources reflected by the reflector 320 should be included in the first edge line and the second edge line, and in order to avoid the light plate stacking defect, the first edge line is designed to deflect a first included angle α toward the lens assembly 400 with respect to the central axis of the lens assembly 400, the second edge line is designed to deflect a second included angle β away from the lens assembly 400 with respect to the central axis of the lens assembly 400, and the first included angle α is smaller than the second included angle β, so that the light supplement light sources emitted by the two sets of light supplement lamp assemblies 300 symmetrically arranged left and right can be spliced into a complete field light supplement area.

Further, the thickness of the light-transmitting region of the lamp cover 500 is uniform, that is, the curved surfaces of the inner surface and the outer surface are parallel to each other, so as to ensure that the light does not undergo an angular change while transmitting through the lamp cover 500.

Further, the light-transmitting area of the lamp cover 500 is not smaller than the area of the light supplement light source emitted by the light supplement lamp assembly 300, so as to ensure that the light supplement light source is not blocked by other light-tight structures; in addition, the area of the gap 150 is larger than the light-transmitting area of the lamp cover 500 to facilitate the assembly of the lamp cover 500.
