Abstract
The invention discloses a far-ray beam luminescence intensity detection method for vehicle headlight tester. It moves light intensity detection board behind the vehicle headlight tester's lens on the vertical surface of beam projection, and after the light intensity detection board entirely through the beam projection area, the collected data by several photoelectric conversion components straight arranged in the light intensity detection board reflect optical distribution condition of the entire beam in the vertical plane of the beam projection, and the data can accurately detect the far-ray beam luminescence intensity of the vehicles headlight. The detection machine to implement the method is: the photoelectric conversion element is installed on the bright light detection board, which locates after the lens in the vehicle headlight tester, and a number of photoelectric conversion elements (4) is laid out in linear order on the light intensity detection board (2), and the light intensity detection board (2) is installed in the drag machine (3). Compared with the existing technologies, the invention has high measurement accuracy, and good applicability to the vehicle headlight which is poor far-ray beam distribution feature.
Description
Technical field
The invention belongs to a kind of high beam light-emitting intensity detecting method of vehicular head light detector and testing agency thereof.
Background technology
At present, the detection method of general vehicle headlamp aligner driving beam luminous intensity is the luminous intensity of the luminous intensity at long-distance light beam center place as headlamp.For the bad headlamp of light distribution, the point of maximum intensity of beam center luminous intensity and light beam luminous intensity has certain error, and therefore the luminous intensity with said method detection vehicle long-distance light light beam also has certain error.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can detect the light distribution property of whole driving beam, measure the high beam light-emitting intensity detecting method of vehicular head light detector and the testing agency thereof of the luminous intensity of driving beam accurately.
The object of the present invention is achieved like this, it is to move on the vertical plane of light beam projection with the light intensity check-out console behind the lens of vehicular head light detector, after the light intensity check-out console passes completely through the projection area of light beam, the data that several photo-electric conversion elements of line spread are gathered on the light intensity check-out console have just reflected the light distribution situation of whole light beam on the vertical plane of light beam projection, and these group data can detect vehicle head lamp driving beam luminous intensity exactly.
Realize said method and design vehicle headlamp aligner driving beam luminous intensity testing agency, light intensity behind the lens in vehicular head light detector detects on the inspection plate and is provided with photo-electric conversion element, laying several photo-electric conversion elements on the light intensity detection inspection plate is arranged in a linear, the light intensity check-out console is contained on the tractor, described tractor is by motor, slide block, screw mandrel, support, lower position switch, upper limit position switch is formed, motor is fixedlyed connected with support, screw mandrel is fixedlyed connected with motor, slide block and screw mandrel flexibly connect, lower position switch, upper limit position switch is fixedlyed connected with support, and described light intensity check-out console is fixedlyed connected with the slide block of tractor.
After the light beam of vehicle head lamp distance light passed lens and converges, tractor moved on the vertical plane of light beam projection driving the light intensity check-out console under the control of controller.In moving process, sample the continuously output quantity of these several photo-electric conversion elements of controller.Pass completely through the projection area of light beam when the light intensity check-out console after, one group of data of gathering the photo-electric conversion element gained have just reflected the light distribution situation of whole light beam on the vertical plane of light beam projection, can detect the luminous intensity of long-distance light light beam exactly with these group data.The present invention has the following advantages compared with the prior art:
1, measuring accuracy height;
2, the bad vehicle head lamp light fixture of driving beam distribution character there is good adaptability.
