Description
Technical field
This utility model relates to the light compensating lamp of intelligent transportation system, specifically a kind of video bayonet socket intelligence stroboscopic light filling lamp.
Background technology
Video bayonet socket high definition system is all weather operations in 24 hours, image forensics is divided into two kinds of the high definition picture of continuous print video flowing and candid photograph, vehicle in high-speed motion is easy to produce streak image, it is necessary for the shutter speed of video camera to improve, shutter speed more hi-vision more will not trail, in photographing principles, shutter speed is more high, the requirement of brightness is more high, when ambient light is slightly weak, the picture that high-speed shutter is taken is just very dark, it is impossible to meet license plate identification demand or the clear basic demand of image, is necessary for increasing light filling equipment.Commonly used two kinds of light filling modes at present: 1, gas flash lamp auxiliary catch captures picture, 2, LED light supplement lamp auxiliary video stream continuously recording.A usual bayonet socket point all adopts both lamps, and namely a light compensating lamp adds a flash lamp.
The advantage of gas flash lamp is that brightness is strong, and image effect is good, it is possible to penetrates glass and illuminates driver's appearance.But its shortcoming is moment blinding too bright, easy, and the life-span is short, 3,000,000 flash of light life-spans will be changed at the local work that vehicle flowrate is many for 1 year.So gas flash lamp has the trend substituted by LED flashing light.
The latest edition of LED light supplement lamp---synchronizing stroboscopic light filling lamp and also popularize gradually in recent years, its ultimate principle is the light on and off that the synchronizing signal utilizing high-definition camera to send controls lamp, and lamp still light yellow always is seen on surface, and actually it has half the time to go out.Compared with conventional light compensating lamp, novel stroboscopic light filling lamp has that light pollution is few, the advantage of remote adjustment brightness, has been widely used in traffic system.
Surface is seen, as long as the voltage x current plus quick-fried sudden strain of a muscle moment raising is just passable in stroboscopic light filling lamp, but actually at all cannot directly superposition.Reason has two aspects: 1, stroboscopic synchronizing signal has strict rate request, and slightly deviation will have a strong impact on the picture quality of video camera shooting, and the switching adding quick-fried glitch will necessarily affect phase place and the speed of stroboscopic circuit originally；2, LED packet arrangement, is already fixed on lamp plate, design time normal working voltage electric current is assumed for stroboscopic, and the high brightness of quick-fried sudden strain of a muscle requires necessarily to improve voltage and current, allows LED moment overload work, and overload capacity must strictly control.
Utility model content

Detailed description of the invention
A kind of video bayonet socket intelligence stroboscopic light filling lamp of the present utility model, as shown in Figure 2, including control chip 1, luminance detection circuit 2, light filling controls output circuit 3, stroboscopic pulse output circuit 4, quick-fried flash pulsing output circuit 5 and LED light supplement lamp 6, the outfan of luminance detection circuit 2 is connected to the respective input of control chip 1, the strobe signal provided by capture machine and quick-fried glitch are separately input into the respective input of control chip 1, light filling controls output circuit 3, the input of stroboscopic pulse output circuit 4 and quick-fried flash pulsing output circuit 5 is connected to the corresponding output end of control chip 1, light filling controls output circuit 3, stroboscopic pulse output circuit 4 is all connected with LED light supplement lamp 6 with the outfan of quick-fried flash pulsing output circuit 5.
Luminance detection circuit 2 is used for controlling to be turned on and off LED light supplement lamp 6 with night daytime.In this utility model, luminance detection circuit 2 can adopt photoconductive resistance to obtain ambient brightness, when the ambient brightness that luminance detection circuit 2 detects is less than the setting value of control chip 1 (night), control chip 1 exports corresponding control signal and controls output circuit 3 to light filling, and light filling control output circuit 3 is opened LED light supplement lamp 6 and carried out light filling.When the ambient brightness that luminance detection circuit 2 detects is more than or equal to the setting value of control chip 1 (daytime), control chip 1 exports corresponding control signal and controls output circuit 3 to light filling, light filling controls output circuit 3 and closes LED light supplement lamp 6, now without light filling.
As shown in Figure 3, stroboscopic pulse output circuit 4 includes switch transistor T 1 and divider resistance R, and the grid of switch transistor T 1 connects the stroboscopic pulse outfan of control chip 1, and the positive pole of LED light supplement lamp 6 connects power supply VCC, the drain electrode of negative pole connecting valve pipe T1, the source electrode of switch transistor T 1 passes through divider resistance R ground connection；Described quick-fried flash pulsing output circuit 5 is provided with switch transistor T 2, and the grid of switch transistor T 2 connects the quick-fried flash pulsing outfan of control chip 1, and the drain electrode of switch transistor T 2 connects power supply VCC, source ground.
Stroboscopic is that LED lights according to certain frequency, extinguishes cyclic process, realizes by controlling the break-make in LED loop.Stroboscopic LED requires that the strobe signal of input is that low level triggers, and we wish can realize LED stroboscopic brightness is controlled, and therefore input signal has to pass through to process and could export to the grid of the switching tube controlling LED light supplement lamp current loop break-make.
In this utility model, in strobe signal, each low level pulse comes interim, a high level pulse is produced after control chip 1 processes, this high level pulse is input to the grid of the switch transistor T 1 controlling LED light supplement lamp 6 current loop break-make, control LED light supplement lamp 6 by this high level pulse and be in the light on and off of certain frequency, and the stroboscopic brightness of LED light supplement lamp 6 can be controlled by controlling the pulse duration of this high level.
Quick-fried sudden strain of a muscle is to send significantly high brightness within very short time, and during quick-fried sudden strain of a muscle, the brightness of lamp is the several times of normal stroboscopic lamp, and stroboscopic lamp can not adopt two set light source and power supplys, therefore we select light source time should meet quick-fried dodge time voltage x current condition.According to LED VA characteristic curve, if as it is shown in figure 1, change suddenly the voltage of LED at Near Threshold, then can realize moment significantly alters the electric current of LED, thus realizing the moment drastic change to LED luminance.
In this utility model, arranging switch transistor T 1 and divider resistance R in stroboscopic pulse output circuit 4, quick-fried flash pulsing output circuit 5 arranges switch transistor T 2 as bypass, and circuit uses constant pressure source VCC to power.As it is shown on figure 3, in normal light filling or stroboscopic function, electric current passes through switch transistor T 1, the voltage being now added in LED light supplement lamp 6 two ends deducts the voltage VR at divider resistance R two ends equal to supply voltage V.When quick-fried glitch arrives, capture machine is to 2 one high level pulses of switch transistor T, now switch transistor T 2 turns on, and divider resistance R is shorted, and is added in the voltage at LED light supplement lamp 6 two ends equal to supply voltage V, it is achieved thereby that the moment of LED light supplement lamp 6 both end voltage changes, it is achieved quick-fried sudden strain of a muscle.
