The utility model relates to an LED lamp light-gathering lighting device for road detection, which comprises an inclined concave cavity lamp holder which is hinged and mounted on a fixed mount plate through an upper adjusting support threaded rod and a lower connecting frame, a plurality lines of L E D lamp rows are mounted on the surface of the inner cavity of the lamp holder through an aluminum-based dead plate, the front portion of each line of LED lamp rows is respectively provided with a cylindrical lens whose front and rear positions and direction can be adjusted, and light emitted by each line of LED lamp rows is focused to be a bright band on a linear array camera shooting position after passing through the cylindrical lens whose direction can be adjusted. When the LED light source is adopted for lighting for a pavement detection linear array camera, after an electric control system is started, light emitted by a plurality of LED lamps is focused on an object plane to form a light band with high brightness after passing through the adjustable cylindrical lens, and the LED lamp light-gathering lighting device for road detection can satisfy the requirements of illuminating with different brightness through adjusting the numbers of lamp rows, the focusing distance of the lamp rows and the lighting elevation angle, thereby adapting to the requirements of detecting mounting structures of different lighting systems for road detection.
Description
Technical field
The utility model belongs to the photovoltaic applications technical field, relates to a kind of auxiliary lighting apparatus that Road Detection is taken, particularly a kind of Road Detection LED lamp concentration illumination device of being used for.
Background technology
In the Road Detection process, the mode that is used for object is carried out digital image capture has two kinds, a kind of is to adopt area array cameras that a specific region of object is taken to obtain a width of cloth two dimensional image, and another kind is to adopt line-scan digital camera that a narrowband region of object is taken to obtain a width of cloth one dimension image.
When taking the object of relative motion, the size of time for exposure is mainly determined by the speed of object of which movement speed.Under the certain situation of the parameter values such as aperture size, time for exposure, shooting distance, photoelectricity receiving chip luminous sensitivity and pixel size of taking imaging system, change fast object in order to take low object of brightness or relative motion, must carry out floor light to object, otherwise, the image of taking will be dark and can't observation analysis because of the low image that causes of object brightness, also will cause image dark because of taking short exposure time to take the rapid movement object.
In the prior art, the mode of the shooting imaging being carried out floor light has two kinds usually, and a kind of is stroboscopic illumination, and another kind is continuous illumination.Take for area array cameras, generally adopt stroboscopic illumination, otherwise can must adopt more powerful lighting source because lighting area is big.Take for line-scan digital camera,, then generally adopt the continuous light source illumination because shooting area is a light belt.
The continuous light belt floor light light source of Road Detection line-scan digital camera employing at present mainly contains ordinary light source, xenon source, halogen light source etc.The general lighting light source (comprises incandescent lamp, sodium vapor lamp, mercury lamp ...) owing to reasons such as its luminous efficiency is low, less so far use.And for present pavement detection still in xenon source and the halogen light source used because its heat that produces when luminous is bigger, easily cause the heating of illuminating source high temperature, have influence on the service life of condenser system to a great extent.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, and then provides a kind of novel structure, luminous efficiency height, life-span long, the Road Detection LED lamp concentration illumination device of conveniently adjusted brightness of illumination and focusing distance.
Technical pattern main points of the present utility model are: the Road Detection LED lamp concentration illumination device that is provided has one and is installed in inclination concave surface chamber lamp bracket on the fixing frame plate by adjusted studdle and following link hinge, surface of internal cavity at lamp bracket is equipped with at least 5 row LED lamp banks by aluminium base fixed head, every row LED lamp bank comprises at least 9 LED lamps, the place ahead at every row LED lamp bank is equipped with a front and back position and the adjustable cylindrical mirror of direction, but the light that is sent by each row LED lamp bank is focused to a bright band in the line-scan digital camera shot location behind the tuning cylindrical mirror.When adopting this led light source to do the pavement detection illumination, after electric control system starts, the light that a plurality of LED lamps send focuses on behind adjustable cylindrical mirror and forms a high brightness light belt on the object plane, and make its focusing distance and shine the inclination angle all adjustable by the hinge device on the lamp bracket, can satisfy the requirement that different brightness are thrown light on by the additions and deletions of lamp bank ordered series of numbers, finally adapt to the requirement of different illuminator mounting structures in view of the above.
Compare with known similar technology, characteristics of the present utility model are to have adopted semi-conductor lighting lamp (LED) technology that has obtained developing rapidly application in recent years.The major advantage of LED has that power savings is remarkable, luminous intensity is high, it successfully has been applied to aspects such as street lamp, garden lamp, military high light torch, with compare with the power incandescent lamp, the luminous intensity of LED lamp is much larger than incandescent lamp, compare with the electricity-saving lamp with power, the luminous intensity of LED lamp also improves several times.Another advantage of LED is to use the life-span long especially, and its theoretical life-span can reach 100,000 hours, and also surpass 50,000 hours actual life, for incandescent lamp and electricity-saving lamp tens times even up to hundred times.The above advantage that the LED light fixture has can effectively solve the not enough problem of illumination that exists in the image of pavement detection line-scan digital camera shooting in the past, the drawing that camera is collected is clear, brightness and good contrast, ambient light interference are little, so it is the perfect light source of line-scan digital camera spotlighting really.In addition, on structural design, the utility model is provided with the hinge governor motion on lamp bracket and lamp bank structure, can make the brightness of illumination of light source and focusing distance adjustable, to adapt to the requirement of different illuminator mounting structures.
