Abstract
The utility model relates to a video pick-up lens. The video pick-up lens comprises a front end cover, a circuit board, a pick-up lens and an LED (light-emitting diode) lamp, wherein an opening is arranged at the front end of the front end cover, the circuit board is fixed inside the front end cover, the pick-up lens is arranged on the circuit board, the LED lamp is electrically connected with the circuit board, a diffuse scattering light-transmitting mirror with a center hole is connected with the opening at the front end of the front end cover in a covering way, and the front end of the pick-up lens is connected with the center hole of the diffuse scattering light-transmitting mirror in a penetrating way. Due to the video pick-up lens, the emitting light of the LED lamp becomes soft and even after the diffuse scattering of the diffuse scattering light-transmitting mirror, thereby solving the problems that when the existing video pick-up lens uses the LED lamp in the dark environment, the light source before the lens in the imaging picture is more rigid, the light and shade contrast ratio is strong, and the picture is vague, therefore, the imaging effect is improved, and the imaging quality on the displaying picture of a monitor is improved.
Description
Technical field
The utility model relates to a kind of pick-up lens, is a kind of video camera lens specifically.
Background technology
Existing video camera lens generally comprise front opening front end housing, be fixed in front end housing inside wiring board, pick-up lens in the circuit board and the LED lamp that is electrically connected with wiring board are installed.The LED lamp is contained in the video camera lens as light source, because its physical characteristic is that the light emitting sheet area is little, luminous flux is big, therefore, and when the combination of adopting many LED lamps strengthens the bright dipping gross power, the emergent ray that is converged just has stronger excitant in dark surrounds, for by the taken scenery of video camera lens, just seem that light source is stiff, the light and shade contrast on the imaging picture is also relatively stronger, and fuzzy pictures is clear inadequately.
The utility model content
The purpose of this utility model just provides a kind of video camera lens, and the pick-up lens front light-source that uses the LED lamp to be caused in dark surrounds is stiff to solve, imaging picture light and shade contrast is relatively stronger and the unclear problem of fuzzy pictures.
The utility model is achieved in that a kind of video camera lens, comprise front opening front end housing, be fixed in the wiring board of described front end housing inside, the LED lamp that is installed in the pick-up lens on the described wiring board and is electrically connected with described wiring board, cover is connected to the diffusion scattering transmission mirror of being with centre bore at the front opening place of described front end housing, and the front end cross-under of described pick-up lens is in the described centre bore of described diffusion scattering transmission mirror.
Described LED lamp is circumference around the periphery that is arranged in described pick-up lens.
Described LED lamp is the arrangement form that is next-door neighbour's inside and outside two circles.
Described LED lamp is an infrared lamp.
The utility model can make in the dark surrounds and become soft, average by the light place before the camera lens on the imaging picture of video camera lens shooting by install the diffusion scattering transmission mirror additional in video camera lens.Its action principle is, lens surface at the diffusion scattering transmission mirror is shaped on irregular pit, or adding has the scattering particulate when eyeglass is shaped, and so just can make the incident light by eyeglass produce unordered refraction, thereby changed the light transmission direction, made the light after the outgoing produce the diffuse scattering effect.The utility model is exactly to make the emergent ray of LED lamp by after the diffuse scattering of diffusion scattering transmission mirror, become soft, average, thereby solved existing video camera lens and used in dark surrounds that the light source before the camera lens is more stiff in the imaging picture that the LED lamp caused, the light and shade contrast is relatively stronger and the unclear problem of fuzzy pictures, improve imaging effect thus, improved the image quality in monitor display frame.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
