Description

Technical Field

[0001] The utility model belongs to the technical field of cameras, and particularly relates to a low-light CCD camera. Background Art

[0002] In the design of traditional low-light CCD cameras, in order to improve the imaging quality in low-light environments, auxiliary lighting devices such as infrared lamps are usually integrated into the camera lens assembly.

[0003] However, this method has certain deficiencies. The stray light generated by lighting devices such as infrared lamps is likely to affect the shooting clarity of the camera and reduce the imaging quality. In addition, traditional cameras often do not take effective anti-vibration measures in the design of the light-transmitting glass, resulting in a small rotation of the light-transmitting glass in a vibrating environment, which may briefly affect the shooting effect of the camera. Summary of the Utility Model

[0008] Further, the outer edge of the limit groove is designed as a bevel, and the sleeve is connected to the outer ring housing of the camera through a thread.

[0009] Beneficial Effects: The design of the utility model is reasonable and has the following beneficial effects:

[0010] 1. In the solution of the present utility model, through the design of the light shielding ring, the influence of internal stray light such as infrared lamps on the camera can be effectively blocked, thereby improving the clarity and contrast of imaging, making the imaging effect in low-light environments more excellent.

[0011] 2. In the solution of the present utility model, the second glass disc is fixed to the light shielding ring to prevent the transparent glass from rotating slightly when vibrating, thereby briefly affecting the shooting effect of the camera. BRIEF DESCRIPTION OF THE DRAWINGS
