Description
Technical field
The LED light filling equipment that the utility model belongs to intelligent transportation bayonet socket, electronic police etc. to be used when taking pictures, especially a kind of intelligent transportation LED flashlamp.
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 conventional analogue video camera; But it to the requirement of illuminance than higher; In automatic license plate identification system and make a dash across the red light electronic police system and other public security supervisory systems, can photograph vehicle image clearly in order to make video camera, just need to use the flashlamp light filling.
Present flashlamp generally is divided into gas flashlamp and LED flashlamp, and the mode of operation of these flashlamp only is trigger pulse formula flash of light, promptly reaches glittering state from the state moment of not working.The light that lightens like this has very strong pungency to people's eyes with neural, belongs to light pollution, can cause certain potential safety hazard to the driver.
As new type light source, the LED flashlamp is place of gas flashlamp progressively, and LED has following advantage by contrast: can continue luminously, luminescence process is controlled easily, and power consumption is little, can practice thrift a large amount of electric energy.But there is shortcoming too in it: cause the life-span to be reduced thereby heat radiation is bad.With present technical merit, LED is to three one-tenth of energy utilization ratio less thaies, thereby has lot of energy and be converted into heat, and how better solving heat dissipation problem has become the main problem that present LED flashlamp faces.The bad meeting of dispelling the heat causes problems such as junction temperature rising, light decay increase, accelerated deterioration.General heating radiator is to be contained in the lamp housing the inside, causes radiating effect poor, and the volume of whole lamp is big, weight is big, and outward appearance is clumsy, and is not easy to install.The big calorimetric that while LED flashlamp produces when lighting for a long time raises the light fixture temperature inside, causes lamp interior to form water vapour attached to the light efficiency that influences 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 the cross bar and can only adjust angle in vertical direction; And can not adjust angle in the horizontal direction, inconvenience is installed, and causes illumination range to have certain limitation.
The utility model content
Defectives such as the utility model is big to the power consumption of the flashlamp that prior art exists, light efficiency is low, installation is inconvenient, light pollution is serious; A kind of intelligent transportation LED flashlamp is provided; Not only efficiently solve the problem of light pollution; And having easy for installationly, heat dispersion is good, advantages such as irradiating angle and scope scalable.
For this reason, the utility model is taked following technical scheme: a kind of intelligent transportation LED flashlamp comprises lamp housing; Be provided with aluminium base in the lamp housing; Aluminium base is provided with the LED lamp, it is characterized in that scribbling heat-conducting silicone grease between described aluminium base and the LED lamp, also scribbles heat-conducting silicone grease between described aluminium base and the lamp housing; The back of said lamp housing forms radiating fin; Form the heat radiation cavity in the lamp housing of said aluminium base bottom, settle power lead and respirator in the described heat radiation cavity, have the air vent of symmetry on chamber, the both sides wall of said heat radiation cavity.The heat that led light source sends passes to lamp housing through aluminium base, and lamp housing directly passes to heat in the extraneous air through the radiator structure at lamp housing back again.Built-in heat radiation cavity two side has air vent, and one is used to connect driving power supply line, and one is used to install respirator.Light fixture is lighted generally speaking, and the lamp housing internal temperature raises, and makes the inside and outside temperature difference that produces of lamp, and respirator can effectively be discharged to the light fixture outside with fog that produces in the course of work and hot gas.The 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, and the lamp housing back also forms the holder of corresponding band gear, behind the gear and the gear matched on the holder on the connecting rod; Fix through a screw again; In the time will rotating the angle of lamp housing, as long as fixed screw is unclamped a little, circular groove being staggered, is axle again with the screw; Rotate to suitable angle, tighten groove afterwards again and screw is accomplished adjusting.
Form vertical sleeve on the described base, described sleeve and connecting rod threaded, the sidepiece of said sleeve has through hole, and a bolt passes the through hole stationary links.Outward winding behind the bolt, remove the threaded engagement of sleeve and connecting rod, connecting rod can 360 degree rotations in sleeve, after waiting to be adjusted to required direction, connecting rod is cooperated with sleeve, and tighten screw rod, and completion is assembled.
Have array hole on the described lamp housing, screw passes said array hole fixing base, a plurality of holes is set connects the thermal diffusivity that substrate can effectively promote substrate.
Described LED lamp is in little bright or half bright state under normal conditions, and when video camera or camera provided trigger pip, the LED lamp reached glittering state of moment.
The utility model adopts from little bright or partly bright to glittering technology of moment, effectively solves the light pollution problem.The external radiating fin of the utility model, built-in respiratory organ structure, effectively promote heat dispersion and can will work in the water spray haze of generation be discharged to the light fixture outside, reduced the light fixture volume, controlled light decay, and prolonged serviceable life.The utility model can be realized the comprehensive angle adjusting of 360 degree after installation, easy for installation, power consumption is little, and light efficiency is high, and light decay is little, and the life-span is long, no light pollution, and 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.
