Abstract
The utility model discloses a wide-angle infrared light night vision camera to solve the technical problem of wider camera covering surface of the camera as well as clearer and more uniform images. In order to solve the technical problem, the technical scheme is adopted: the wide-angle infrared light night vision camera comprises a camera shooting lens arranged on a mounting base and an infrared light supply, wherein, the mounting base with a metal material structure is arranged at the upper end of the camera shooting lens, and the infrared light supply integrated by a plurality of wide-angle infrared LED chip arrays is arranged in the position where the surface of the mounting base is vertical to the camera shooting lens. Compared with the prior art, a plurality of LED chips are coated with a coating layer after being integrally encapsulated; since the chips are not provided with optical lenses like focusing lenses of the traditional LED, the original half-power angle thereof can reach a wide-angle of 135 degrees to 150 degrees; moreover, the mounting base of the camera also adopts an aluminum alloy mounting base or other universal metal materials, thereby further enhancing the heat dissipation function of the whole camera and prolonging the service life of the light source.
Description
Technical field
The utility model relates to a kind of wide-angle infrared night vision cam, especially relates to a kind of infrared night vision camera with wide-angle light source.
Background technology
General wide-angle infrared night vision cam in the prior art, pick-up lens is connected on the mount pad, and infrared light supply is set on head shell, realizes the function of night vision camera, infrared light supply is to coat a led chip in clad, respectively draw two pins again, two pins except that realize with effect that power supply is connected, dispel the heat and also lean on this bipod to realize, radiating effect is poor, thereby efficient is lower, and is bright inadequately, usually in order to increase brightness, adopt lens light gathering for each LED luminophor, make it can shine fartherly, but use after the lens light gathering, the angle of irradiation has diminished, at the night vision state, monitor can be seen the light beam as the picture electric torch, and middle bright, the edge is dark, can't cover big zone and if use a plurality of LED simultaneously, each luminophor all needs to be equipped with lens, and it is big that volume becomes, and is unfavorable for the miniaturization of product.
Summary of the invention
The purpose of this utility model provides a kind of wide-angle infrared night vision cam, and the technical matters that solve is to make that the shooting coverage rate of camera is wider, and picture is more clear evenly.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of wide-angle infrared night vision cam, comprise the pick-up lens and the infrared light supply that are arranged on the mount pad, the upper end of described pick-up lens is provided with the mount pad of metal structure, is provided with on position vertical with pick-up lens on the surface of mount pad by the integrated infrared light supply of a plurality of wide-angle infrared LED chip arrays.
Infrared light supply of the present utility model is with circular, square, rhombus or polygon integrated array.
Mount pad of the present utility model is aluminum alloy materials or general heat radiating metal material.
A kind of wide-angle infrared night vision cam, comprise the pick-up lens and the infrared light supply that are arranged on the mount pad, the upper end of described pick-up lens is provided with the mount pad of metal structure, and described periphery at pick-up lens is provided with by a plurality of wide-angle infrared LED chip arrays and the infrared light supply that becomes one.
Infrared light supply of the present utility model is annular integrated array.
The rear end of infrared light supply of the present utility model is provided with metal fin.
Metal fin of the present utility model is aluminum alloy materials or general heat radiating metal material.
The half-power angle of infrared light supply of the present utility model is the 135-150 degree.
Mount pad of the present utility model is provided with hemispherical shell.
The utility model compared with prior art, be coated with coating layer after adopting the integrated encapsulation of a plurality of led chips, because chip does not add like the condenser lens of traditional LED optical mirror slip so its original angle reaches the wide-angle of 135-150 degree, infrared light supply has been realized the irradiation of extensive angle, the scope that infrared light can shine is the camera lens maximum scope of finding a view head and shoulders above, infrared dome type camera can make the clear large tracts of land that covers equably of whole image, the dark situation of bright limb in the middle of can not occurring; And because the multicore sheet is integrated, volume is little so total brightness is enough; This clad has protective effect for the metal wire of packaging LED chips; prevent that it is exposed and rupture; metal substrate adopts the aluminium base or the copper base of good heat dissipation effect; and the mount pad of camera also adopts aluminium alloy mount pad or other general heat radiating metal materials; further strengthen the heat sinking function of whole camera, prolonged the life-span of light source.
The clad of described led light source adopts other to meet the not material of easy fracture of heat, makes its life-span can reach ten times of led light source of common employing epoxy resin coating film.Because infrared light supply has metal substrate, and metal substrate connecting aluminium alloy or other heat radiating metal material mount pads, so good heat dissipation effect can be integrated on this metal substrate by some infrared LED chips, realized high power, high brightness.
