Description
Technical field
The utility model relates to a kind of infrared illumination equipment, relates in particular to a kind of fechtable CCD/CMOS video camera image vertical synchronizing signal, drives the lighting apparatus that is made of infrared light-emitting diode.
Background technology
For at home and in the society now that raises gradually of office's awareness of safety, the installation of monitor is popularized people.
If existing surveillance equipment adopt is not had a video camera of infrared pick-up function, still can photograph sharp image by day, but when one to pitch-dark or evening, because insufficient light, to cause the captured image effect of monitor to have a greatly reduced quality, even it be black to become a slice, can't manifest any picture; And then have the people to install inductor additional, as long as have the people near the time start the irradiation light reinforcement of another outer dress, yet the invador is very easy to find and destroys the equipment of this visible light, makes monitor lose the effect of supervision; The existing at present monitor of night vision infrared camera that adopts comes out, yet this equipment can suffer from aforementioned picture insufficient light situation equally, and it is auxiliary still to need the infrared illumination module.
Existing on the market infrared illumination module mostly is to adopt alternating voltage 110V/60Hz or 220/50Hz, become direct current through rectification, yet by using low-voltage DC directly to drive the infrared illumination module, to cause the infrared light emission assembly overheated, and power consumption is very big, and the heat dissipation problem that can't effectively handle of subsidiary generation, usually causes its brightness sharply depleted, shorten the ordinary life of LED, even LED can be burnt.And another kind is to be used as the infrared illumination module of driving by vibrate the voluntarily synchronizing signal of 50/60Hz of inside, however vibrate the frequency that often with video camera signal and asynchronous, so cause image frame flicker and extremely unstable.Practising existing articles for use as for another kind then is that acquisition ac power frequency 50/60Hz is used as synchronizing signal, drive the infrared illumination module, because video camera is not to be that to adopt mains frequency to make image synchronous entirely, therefore equally can cause image frame flicker and extremely unstable yet.
The utility model content
Main purpose of the present utility model is to provide a kind of infrared illumination equipment, causes infrared camera film flicker and unsettled defective easily to solve existing infrared illumination module.
For reaching above-mentioned purpose, the utility model provides a kind of infrared illumination equipment, and this infrared illumination equipment comprises:
One light-emitting device comprises the plural number piece infrared light-emitting diode that couples mutually;
One switch element is coupled to this light-emitting device, to control the loop conducting of infrared light-emitting diode in this switching device;
One synchronous signal capturing module is coupled to this infrared camera, receiving a raw video signal, and captures the vertical synchronizing signal output of this raw video signal;
One signal correcting module is coupled to this sync signal acquisition module, receives this vertical synchronizing signal and revises, and drives signal synchronously to export one; And
One driver module is coupled to this signal correcting module, receives this driven in synchronism signal and amplifies, and driving the keying of this switch element, and then the control infrared light-emitting diode flickers, and produces an infrared illumination light.
Above-mentioned infrared radiation module can be by the vertical synchronizing signal of acquisition infrared camera image, drive the light-emitting device that light emitting diode constitutes, with auxiliary night illumination, make that the image frame of infrared camera is stable not to glimmer, and light-emitting device is low in energy consumption, Sheng Gaore not, can reach to increase the service life and benefits such as energy-saving and carbon-saving.
Description of drawings
Fig. 1 is the system architecture schematic diagram of infrared illumination equipment of the present utility model.
Specific embodiment
Below in conjunction with Figure of description the specific embodiment of the present utility model is done detailed description.Obviously, described embodiment only is a part of embodiment of the present utility model, and other embodiment that those skilled in the art is obtained under the prerequisite of not paying creative work belongs to protection domain of the present utility model.
As shown in Figure 1, the disclosed infrared illumination equipment 1 of the utility model embodiment is to cooperate an infrared camera 3 operate together, and floor light is provided.This infrared illumination equipment 1 includes a light-emitting device 10, a power transfer module 11, one synchronous signal capturing module 12, a signal correcting module 13, a driver module 14 and a switch element 15.
Light-emitting device 10 includes the plural number piece infrared light-emitting diode that couples mutually, can produce the infrared ray black light, its wavelength is about 850nm, cooperates the running of infrared camera 3 or monitoring equipment device drives, down auxiliary at it, the captured image in night or dark place also can be bright as daytime.Subsidiary one what carry is that infrared light-emitting diode is generally with common more in parallel after the array series connection, to reach specific electrical specification.
Sync signal acquisition module 12 is coupled to infrared camera 3, and a raw video signal of receiving infrared-ray video camera 3 outputs captures the vertical synchronizing signal output of this raw video signal.In specific embodiment, sync signal acquisition module 12 can adopt an existing video signal sync separator (video synchronousseparator) to come the vertical synchronizing signal of pick-up image signal.
By the foregoing description as can be known, this infrared illumination equipment is by the vertical synchronizing signal of the raw video signal of acquisition infrared camera, infrared light-emitting diode with the driven in synchronism light-emitting device flickers, produce floor light light, do not glimmer making that the image frame of infrared camera is stable.In addition, light infrared light-emitting diode, can make light-emitting device low-power consumption, low temperature, and then reach and increase the service life and benefit such as energy-saving and carbon-saving based at interval (synchronously promptly).
What deserves to be explained is that the Synchronization Design of above-mentioned infrared illumination equipment and infrared camera also is applicable in the application example of this equipment and a use of other corollary equipments, and improves the stability of corresponding corollary equipment with this.
More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
