Description
Technical field
The LED light filling equipment using when the invention belongs to intelligent transportation bayonet socket, electronic police etc. and taking pictures, especially a kind of Intelligent traffic LED flash lamp and circuit thereof.
Background technology
High-definition digital video camera and camera are the new products that is applied to intelligent transportation field, its resolution is than the high several times of traditional analog video camera, but it is higher to the requirement of illuminance, in automatic license plate identification system and red light running electronic police system and other public security supervisory systems, in order to make video camera can photograph vehicle image clearly, just need to use flash lighting.
Current flashlamp is generally divided into gas flashlamp and LED flashlamp, and the mode of operation of these flashlamp is only trigger pulse formula flash of light, reaches glittering state from the state moment of not working.The light lightening like this has very strong pungency to people's eyes and nerve, belongs to light pollution, can cause certain potential safety hazard to driver.
As new type light source, LED flashlamp is place of gas flashlamp progressively, and LED has following advantage by contrast: can continue luminously, luminescence process is easily controlled, and power consumption is little, can save a large amount of electric energy.But it is existent defect too: thus dispel the heat the bad life-span reduction that causes.With current technical merit, LED is to three one-tenth of the utilization factor deficiencies of energy, thereby to have a large amount of Conversion of Energies be heat, and how better solving heat dissipation problem has become the main problem that current LED flashlamp faces.The bad meeting of dispelling the heat causes the problems such as junction temperature rising, light decay increase, accelerated deterioration.General heating radiator is to be contained in lamp housing the inside, causes radiating effect poor, and the volume of whole lamp is large, weight is large, and outward appearance is clumsy, and is not easy to install.The large calorimetric that LED flashlamp produces when lighting for a long time simultaneously, raises light fixture temperature inside, causes lamp interior to form water vapour and is attached to the light efficiency that affects on glass.
In addition, existing flashlamp is only considered the forward light filling of taking pictures, and does not consider the side light filling of taking pictures, be fixed on cross bar and can only adjust in the vertical direction angle, and can not adjust in the horizontal direction angle, inconvenience is installed, and causes illumination range to there is certain limitation.
Summary of the invention
The defects such as the power consumption that the present invention is directed to the flashlamp that prior art exists is large, light efficiency is low, installation is inconvenient, light pollution is serious, a kind of Intelligent traffic LED flash lamp and circuit thereof are provided, not only efficiently solve the problem of light pollution, and have easy for installation, the advantages such as heat dispersion is good, and irradiating angle and scope are adjustable.
For this reason, the present invention takes following technical scheme: a kind of Intelligent traffic LED flash lamp, comprise lamp housing, in lamp housing, be provided with aluminium base, aluminium base is provided with LED lamp, it is characterized in that scribbling heat-conducting silicone grease between described aluminium base and LED lamp, between described aluminium base and lamp housing, also scribble heat-conducting silicone grease, the back of described lamp housing forms radiating fin, in the lamp housing of described aluminium base bottom, form heat radiation cavity, in described heat radiation cavity, settle power lead and respirator, on chamber, the both sides wall of described heat radiation cavity, have symmetrical air vent.The heat that LED light source sends passes to lamp housing by aluminium base, and lamp housing directly passes to heat in extraneous air by the radiator structure at lamp housing back again.Built-in heat radiation cavity two side has air vent, and one for connecting driving power supply line, and one for installing respirator.Generally light fixture is lighted, and lamp housing internal temperature raises, and makes the inside and outside temperature difference that produces of lamp, and respirator can effectively be discharged to light fixture outside by the fog producing in the course of work and hot gas.Lamp housing back forms heat radiation fin structure also can quick heat radiating.
The bottom of lamp housing also comprises interconnective connecting rod and base, and described connecting rod and lamp housing are hinged.Small end forms circular gear, lamp housing back also forms the corresponding holder with gear, gear on connecting rod is with after gear on holder coordinates, by a screw, fix again, in the time will rotating the angle of lamp housing, as long as fixed screw is unclamped a little, circular groove is staggered, then take screw as axle, rotate to suitable angle, clamp again afterwards groove and screw is completed to adjusting.
On described base, form vertical sleeve, described sleeve and connecting rod threaded, the sidepiece of described sleeve has through hole, and a bolt is through through hole stationary links.Outward winding after bolt, remove the threaded engagement of sleeve and connecting rod, connecting rod can rotate by 360 degree in sleeve, to be regulated after required direction, then connecting rod is coordinated with sleeve, and tightens screw rod, completes assembling.
On described lamp housing, have array hole, screw, through described array hole fixing base, arranges a plurality of holes and comes connection substrate can effectively promote the thermal diffusivity of substrate.
Described LED lamp is under normal conditions in glimmer or half bright state, and when video camera or camera provide trigger pip, LED lamp reaches glittering state of moment.
The present invention adopts from glimmer or half bright to glittering technology of moment, effectively solves light pollution problem.External heat radiation fin of the present invention, built-in respiratory organ structure, effectively heat radiation performance also can be discharged to light fixture outside by the water spray haze producing in work, has reduced light fixture volume, has controlled light decay, and has extended serviceable life.The present invention can realize 360 degree omnibearing angels and regulate after installation, and easy for installation, power consumption is little, and light efficiency is high, and light decay is little, and the life-span is long, and without light pollution, outward appearance is small and exquisite attractive in appearance.Connecting rod and lamp housing adopt axle rotation and screw thread rotation fit structure, and installation and adjusting angle are convenient.
