Abstract
The utility model discloses a kind of video camera LED lamp panel radiating subassembly, include the insulating heat-conductive plate of fitting with the LED lamp panel back side, the heat-conducting plate of fitting with insulating heat-conductive plate, and the thermal insulation board be arranged on heat-conducting plate, described insulating heat-conductive plate covers the pin of described LED, the edge of described heat-conducting plate is formed with the flanging of accommodating thermal insulation board, and described flanging and fore shell inwall are pasted together.The heat that LED produces is delivered to heat-conducting plate through insulation heat-conducting plate, be delivered to video camera fore shell by the flanging of heat-conducting plate again, thus add area of dissipation, and camera and thermal source are isolated by thermal insulation board, prevent heat from passing to other devices by camera, further ensure picture quality.
Description
Technical field
The utility model relates to a kind of CCTV camera, especially relates to a kind of CCTV camera LED board radiating subassembly.
Background technology
Along with the raising of awareness of safety, the performance of people to security protection video camera proposes requirements at the higher level, in order to high-quality image effect can be taken at night, existing video monitoring video camera adds a circle light compensating lamp around camera, be generally highlighted light emitting diode (LED), when dark, camera can open light compensating lamp automatically according to the light environment of surrounding, to make up the deficiency of light.But multiple LED opens for a long time and can produce certain heat, the signal to noise ratio (S/N ratio) of easy effect diagram picture, pickup quality will be affected.Prior art have employed the heat dissipation problem that multiple method solves LED, and several frequently seen scheme is below shown:
1, LED is exposed, although heat directly can be dispersed in air, the outward appearance of Total Product can be destroyed.
2, LED is placed in CCTV camera inside, use fewer LED to reduce heat, product design is attractive in appearance, but illumination capability decreases, and picture quality is not high.
3, LED is placed in CCTV camera inside, increase louvre in the suitable position of shell, but all can there be considerable influence the quantity in hole and position to outward appearance and radiating effect, and dust, insect also can enter video camera inside from hole, affect photographic effect.
4, LED is placed in video camera inside, shell uses metal shell completely, dispels the heat by the feature of metal self, and radiating effect is better, but cost is higher.
5, LED is placed in video camera inside, shell is use plastic shell completely, and the spatial design thermal conductive metal plate suitable in inside, is passed to heat on thermal conductive metal plate, dispels the heat in the space of inside.But general inner space is less, heat radiation is helped little.
Utility model content
The utility model is to solve existing issue, provides a kind of CCTV camera LED lamp panel radiating subassembly, adopts that the CCTV camera picture quality of this radiating subassembly is high, good looking appearance, cost are lower.
For achieving the above object, the utility model is by the following technical solutions: a kind of CCTV camera LED lamp panel radiating subassembly, be arranged in the fore shell of CCTV camera, successively LED lamp panel is installed in described fore shell, radiating subassembly and camera, described LED lamp panel is welded with some LED, the through hole having a permission camera to pass in the middle of described radiating subassembly, it is characterized in that: described radiating subassembly includes the insulating heat-conductive plate of fitting with the LED lamp panel back side, the heat-conducting plate of fitting with insulating heat-conductive plate, and the thermal insulation board be arranged on heat-conducting plate, described insulating heat-conductive plate covers the pin of described LED, the edge of described heat-conducting plate is formed with the flanging of accommodating thermal insulation board, and described flanging and inner walls are pasted together.
Further, the dual coating of described insulating heat-conductive plate has heat conductive silica gel.
Further, described heat-conducting plate is graphite cake.
Further, described thermal insulation board is that heat insulation foam is made.
The utility model beneficial effect is compared with prior art: this CCTV camera LED lamp panel radiating subassembly radiating subassembly includes the insulating heat-conductive plate of fitting with the LED lamp panel back side, the heat-conducting plate of fitting with insulating heat-conductive plate, and the thermal insulation board be arranged on heat-conducting plate, described insulating heat-conductive plate covers the pin of described LED, the edge of described heat-conducting plate is formed with the flanging of accommodating thermal insulation board, and described flanging and fore shell inwall are pasted together.The heat that LED produces is delivered to heat-conducting plate through insulation heat-conducting plate, be delivered to video camera fore shell by the flanging of heat-conducting plate again, thus add area of dissipation, and camera and thermal source are isolated by thermal insulation board, prevent heat from passing to other devices by camera, further ensure picture quality.

Fig. 1 is the explosive view that the utility model is applied to CCTV camera;
Fig. 2 is the structural drawing that the utility model is installed in fore shell;
Fig. 3 is the side sectional view of Fig. 2.
Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model being described further and illustrating.
Fig. 1 ~ 3 show a kind of CCTV camera LED lamp panel radiating subassembly, this radiating subassembly is arranged at the back side of the inner LED lamp panel 3 of CCTV camera, the through hole having a permission camera 7 to pass in the middle of described radiating subassembly, this radiating subassembly comprises insulating heat-conductive plate 4, heat-conducting plate 5, thermal insulation board 6, described insulating heat-conductive plate 4 fits in the back side of described LED lamp panel 3, cover the pin of all LED completely, to realize the isolation of electrified body, the heat that LED produces is delivered to heat-conducting plate 5 simultaneously.In order to realize this function, this insulating heat-conductive plate 4 can be made up of common heat conductive insulating rubber, and in order to reach better effect, insulating heat-conductive plate 4 dual coating has heat conductive silica gel.Described heat-conducting plate 5 fits on insulating heat-conductive plate 4, and the edge of described heat-conducting plate 5 is formed with flanging 51, and described flanging 51 is closely pasted together, by heat conduction to video camera fore shell 1 with described video camera fore shell 1 inwall.Preferably, described heat-conducting plate 5 is graphite cake, has fabulous heat conductivility.Described thermal insulation board 6 is covered on heat-conducting plate 5, and effect is isolated at camera 7 and thermal source, prevents heat from passing to other devices by camera 7, reduce signal noise ratio (snr) of image, affect picture quality.Described thermal insulation board 6 is preferably heat insulation foam material and makes.
During assembling, first insulating heat-conductive plate 4 is covered on LED lamp panel 3 back side, then pastes heat-conducting plate 5, thermal insulation board 6 successively, then by the camera 7 of video camera through the through hole of this radiating subassembly, aim at eyeglass 2, finally fix each parts.
The utility model structure is simple, easily manufactured, the heat that LED produces can be delivered to video camera fore shell, thus increase area of dissipation, ensure that the high-quality of brightness of illumination and image simultaneously.In addition, due to this structure perfect heat-dissipating, so video camera fore shell adopts plastic material, without the need to adopting metal material, saved manufacturing cost, external form is also more attractive in appearance.
More than state only with embodiment to further illustrate technology contents of the present utility model; so that reader is easier to understand; but do not represent embodiment of the present utility model and be only limitted to this, any technology done according to the utility model extends or recreation, all by protection of the present utility model.
