Abstract

The invention provides a diaphragm adjusting mechanism for a star-grade road monitoring zoom camera lens. The diaphragm adjusting mechanism comprises a diaphragm piece (17), a cam plate (16) and a diaphragm seat (9), wherein the cam plate (16) is in rotatable connection with the diaphragm seat (9); the diaphragm piece (17) is connected with the cam plate (6) through a movable groove; the diaphragm piece (17) is in a crescent shape; a diaphragm guide screw (170) is arranged at each of the two ends of the diaphragm piece (17); and the two diaphragm guide screws (170) are arranged on two side surfaces of the diaphragm piece (17) respectively and protrude outwards. The star-grade road monitoring zoom camera lens adopting the diaphragm adjusting mechanism utilizes an oversized aperture technology and an aperture value reaches F2.0; furthermore, the camera lens adopts a multilayered broad width film plating technology and an ultralow chromatic dispersion optical glass technology so that the light transmission rate is effectively improved, and glaring, ghost image and other phenomena, which easily occur in a common camera lens, are alleviated; and the camera lens has advantages in aspect of appearance.

Description

technical field [0001] The invention relates to the field of lenses, in particular to an aperture adjustment mechanism for a star-level road monitoring zoom lens. Background technique [0002] Although the traditional infrared supplementary light technology can obtain clear images under low illumination, it will lose color and can only form black and white images. Moreover, through infrared supplementary light, highly reflective objects such as license plates are easily overexposed, while clothing colors, Car body color, license plate, etc. are often the key clues to solve the case, and cannot be lost—so there is an increasing demand for clear color imaging under low illumination. [0003] Low-light cameras are hot products in the monitoring industry launched with the development of semiconductor technology in recent years. A low-light camera, literally, refers to a camera that can still obtain relatively clear images under low-light conditions. At present, the security in...
