Description

Technical Field

[0001] The utility model relates to camera manufacturing technology, in particular to a fill light device for a camera. Background Art

[0002] Cameras often face working environments in dim scenes. In order to ensure the clarity of the captured images, fill light devices are installed on the cameras. Especially for multi-eye and multi-directional cameras, since their shooting range is wider, the requirements for fill light devices are higher. Figure 1 The schematic diagram of a multi-eye multi-directional camera in the prior art is shown. The multi-eye multi-directional camera includes a lens portion 1 and a fill light device 2. The lens portion 1 is protruded at one end of the multi-eye multi-directional camera, and the fill light device 2 is annularly surrounding the lens portion 1. Figure 2 The fill light device 2 in the prior art includes a plurality of fill light units 20 evenly arranged in a circle, each fill light unit 20 includes a lamp board and lamp beads arranged on the lamp board, and all the lamp boards are tangent to a virtual circle S coaxial with the lens portion 1. In this fill light device, if the number of fill light units 20 is small and the intervals are large, blind spots are likely to exist between the irradiation areas of two fill light units 20. If the number of fill light units 20 is increased and the fill light units 20 are arranged more closely, the overlap of light may easily cause the problem of uneven light in the fill light device 2 as a whole, resulting in reflection and unevenness of the image captured by the camera, affecting the image quality.

[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0021] See also Figure 3-Figure 5 As shown, as a preferred embodiment of the utility model, a camera is provided, comprising a housing 3, a lens unit 1 and a fill light device 2. The lens unit 1 is convexly arranged at one end of the camera. In this embodiment, the camera is specifically a multi-eye multi-directional camera. The lens unit 1 comprises a plurality of cameras 11 and a ball cover 12 covering the plurality of cameras 11. The fill light device 2 is arranged around the lens unit 1 and is used to fill light for the shooting environment of the lens unit 1.

[0022] The fill light device 2 includes an annular base 21 fixedly connected to the housing 3, a window 210 is provided on the annular base 21, and a fill light unit 20 is fixedly installed in the window 210. The fill light unit 20 is used to realize light emission. A light-transmitting lens 22 covers the window 210, and an annular light-transmitting cover 23 covers the entire annular base 21. Such a configuration can better seal the fill light unit 20 and improve the dustproof effect.

[0023] like Figure 5 There are several fill light units 20, which are evenly distributed in a circle. Each fill light unit 20 includes a first light board 201 and a second light board 202. The first light board 201 and the second light board 202 are arranged in the circumferential direction of the fill light device 2. The facing ends of the first light board 201 and the second light board 202 are inclined toward the outside of the fill light device 2, so that the first light board 201 and the second light board 202 form a "V"-shaped structure protruding toward the outside of the fill light device 2. Lamp beads are arranged on the first light board and the second light board. In this embodiment, in the arrangement direction of the first light board 201 and the second light board 202, a lamp bead is arranged at each end of the first light board 201, and a lamp bead is arranged at each end of the second light board 202. Compared with the fill light device in the prior art, the fill light device 2 of the present embodiment expands the light range of the fill light unit 20 and reduces the light-emitting blind area of ​​the fill light unit 20 through the "V"-shaped inclined structure of the first light board 201 and the second light board 202. Combined with the arrangement of the lamp beads at both ends of the first light board 201 and the second light board 202, the fill light unit 20 further emits light more evenly, thereby avoiding the problems of image reflection and image unevenness when shooting with the lens part 1.

[0024] In this embodiment, the first light board 201 and the second light board 202 are both inclined relative to the axis T of the lens head 1, so that the light of the fill light device 2 is diverged toward the outside of the lens head 1 to enhance the fill light effect.

[0025] like Figure 6 In this embodiment, the fill light device 2 further includes a light board bracket 23, on which a mounting groove is provided, in which the first light board 201 and the second light board 202 are fixedly mounted, and the light board bracket 23 is fixedly connected to the housing 3.
