Description
Technical field
The utility model belongs to lighting device heat dissipation technology field, is specifically related to a kind of heat abstractor of light fixture.
Background technology
Road (comprising town road, highway etc.) pavement detection is a kind of necessary regular operation of monitoring pavement of road disease and road upkeep demand.Along with the continuous increase of China's highway total kilometrage, China has become a highway big country, and mileage open to traffic is long, and area distribution is wide, and this just makes the workload of Road Detection very huge.And Road Detection requires the above crackle of the 1mm occurring on road surface to be detected conventionally, accuracy requirement is high.As the basic data of road upkeep, also must ensure the promptness of pavement disease data, road is open to traffic, sleety weather all can cause infringement in various degree to road, and basic data obtains more early road upkeep is more of practical significance.Current domestic colleague mainly adopts automatic collection pavement disease image, the basic data such as kind and reference area of manual identified pavement disease, so not only expend a large amount of artificial, and basic data to obtain the time long, human error causes degradation under accuracy, makes troubles to road maintenance work.For addressing the aforementioned drawbacks, this just need realize Computer Automatic Recognition pavement disease data, and the key technology that realizes this Intelligent Measurement adopts linear scanning imaging technique exactly, by the digitlization of pavement disease image information, is automatically identified by supercomputing.Be expert at and sail road pavement under state and carry out line sweep owing to detecting vehicle, detect the shade of vehicle self, the object in the shade of adjacent lane driving vehicle and road overhead is (as electric wire, building, trees, illumination or the vertical rod of monitoring system etc.) shade that produces, in the time of Computer Automatic Recognition, these shades are because the parallel light-struck characteristic of sunlight all can produce a kind of false crackle, the unique method that these false crackles will be eliminated is exactly, on detection vehicle, light filling illuminator is installed, irradiate on the ground with sufficiently high brightness, carrying out computer when identification and carry out shade and eliminate or weaken the degree of depth of shade, that computer is identified less than shade, thereby ensure the accuracy rate of computer identification.Or in the time working at night, reach sufficiently high light-source brightness, to meet the condition for identification accuracy rate of eliminating computer road pavement disease geo-radar image.This requirement to artificial light sources brightness is quite high, and under the brightness that can normally work, even cloudy weather, the sunlight brightness on road surface is still up to 3000cd/m
2above, this increases substantially brightness concerning artificial light sources is extremely difficult, to such an extent as in the detection of pavement of road, does not have to meet the light filling illuminator that reaches the automatic testing requirement of intelligent computer at present.
At present, in the detection of pavement of road, illuminator used mainly contains three kinds of modes, below briefly explains this three kinds of modes and weak point thereof.

(2) conventional light source illumination
Conventional light source is mainly the non-pneumatic charging sources such as iodine-tungsten lamp, the light efficiency of this light source self is lower, adding is spatial point light source, because the field of illumination of detecting is very narrow, cause more than 80% light just can use irradiation area by reflection, the effective luminous efficacy of light fixture is very low, and current existing conventional light source light filling lighting only can meet the manual detection of low speed surface imaging, therefore the light filling lighting of, making with conventional light source is difficult to reach the needed brightness of autonomous detection.
(3) glow discharge spot lamp illumination
Glow discharge spot lamp is mainly taking metal halide light as main, similar with the light filling lighting that conventional light source is made, light fixture bulky, power consumption is very large, although the light efficiency of gas-discharge lamp is higher than conventional light source, but because of the characteristic of its spatial point light source, the effective luminous flux of light fixture is very low, and make it be difficult to reach the brightness requirement that computer intelligence detects.
Above three kinds of lighting devices all do not have heat abstractor, and light filling lighting hours is short, the life-span is also under some influence simultaneously.
