The scheme that the utility model solves further technical problem is: described luminous element is array distribution, is arranged on the main body, is used to be excited and sends infrared light.
The scheme that the utility model solves further technical problem is: described bright dipping cover is arranged on the main body and surrounds this luminous element.
The scheme that the utility model solves further technical problem is: described electrode links to each other with circuit in being arranged on main body and is used for the driven for emitting lights body running.
The scheme that the utility model solves further technical problem is: it further comprises a heat sink, and described heat sink links to each other with main body, and with this electrode insulation.
The scheme that the utility model solves further technical problem is: described led array light source is arranged on the below of this camera lens.
The scheme that the utility model solves further technical problem is: described led array light source is a plurality of, be arranged on camera lens around.
The scheme that the utility model solves further technical problem is: described heat sink be integral type or laminated structure.
Compared to prior art, the video camera of band integrated infrared LED array of the present utility model adopts the led array light source, under the identical requirement that goes out luminous intensity, make volume littler, use more convenient, the design that adds heat sink and go out light shield, the useful life of the video camera of this band integrated infrared LED array that not only prolongs greatly, and also the video camera of band integrated infrared LED array infrared goes out optical property and shoots with video-corder effect and all improved greatly.

Embodiment
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
As shown in Figure 2, the video camera of band integrated infrared LED array of the present utility model comprises led array light source 20, camera lens 40, support 50 and shell 60.Described support 50 is in order to supporting housing 60, and this shell 60 is coating camera lens 40 in order to protect this camera lens, and described led array light source 20 is arranged on the below of this camera lens 40.
See also Fig. 3 and Fig. 4, it comprises main body 21 this led array light source 20, and at least one luminous element 22 goes out light shield 23, electrode 24 and heat sink 25.Described luminous element 22 is array distribution, is arranged on the main body 21, is used to be excited and sends infrared light.Describedly go out light shield 23 and be arranged on the main body 21 and surround this luminous element 22, its effect is that the infrared light that luminous element 22 sends is carried out converging of light beam, adjusts the angle of bright dipping, improves the brightness of bright dipping and controls out direction of light.Described electrode 24 links to each other with circuit in being arranged on main body 21 and is used for 22 work of driven for emitting lights body, and described heat sink 25 links to each other with main body 21, and insulate with this electrode 24.
