Abstract
The utility model discloses a light intensity detecting board of a vehicle headlight detecting instrument including a light intensity detecting board, a optical-electrical converting element positioned on the light intensity detecting board. A light intensity (2) is positioned on the drive mechanism (3) which can move on the surface which is vertical with the light beam, and optical-electrical converting elements (4) which are arranged in a line are positioned on a light intensity detecting board (2). Comparing to the prior art, the utility model has a high detecting precision and a good suitability for the vehicle headlights that has a bad far beam distribution character.
Description
Technical field
The utility model belongs to a kind of vehicular head light detector light intensity check-out console.
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.The detection architecture of existing vehicular head light detector driving beam luminous intensity is a fixing photo-electric conversion element, what detect is the luminous intensity at long-distance light beam center place, the luminous intensity of the luminous intensity of this point as the long-distance light light beam.For the light bad headlamp that distributes, the point of maximum intensity of the luminous intensity of beam center and the luminous intensity of light beam has certain error, and therefore the luminous intensity with the driving beam of this vehicle head lamp automatic tester detection also has certain error.
Summary of the invention
The purpose of this utility model provides a kind ofly can detect the light distribution property of the whole distance light light velocity, measure the vehicular head light detector light intensity check-out console of the luminous intensity of distance light accurately.
The purpose of this utility model is to realize like this, it is provided with the photo-electric conversion element that light intensity check-out console, light intensity check-out console are provided with, the light intensity check-out console is contained in can have the photo-electric conversion element of line spread on the light intensity check-out console on the tractor that moves on the vertical plane of light beam projection.
The utility model is owing to adopt tractor, and 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 utility model 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.

Embodiment
With reference to Fig. 1, Fig. 2, the photo-electric conversion element 4 that has a straight line to arrange on the present embodiment light intensity check-out console 2.Photo-electric conversion element 4 adopts photoelectric cell.Light intensity check-out console 2 is contained in can be on the tractor 3 that moves on the vertical plane of light beam projection.After the light beam of vehicle head lamp distance light passed lens 1 and converges, its light beam was incident upon and is light beam projecting 6 on the screen 5, and tractor 3 moves on the vertical plane of light beam projection driving light intensity check-out console 2 under the control of controller.Tractor 3 drives light intensity check-out console 2 and moves as shown in Figure 3 at the vertical plane above-below direction of light beam projection under the control of controller.Perhaps tractor 3 drives light intensity check-out console 2 and moves as shown in Figure 4 at the vertical plane left and right directions of light beam projection 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.With reference to Fig. 5, described tractor 3 is made up of motor 7, slide block 8, screw mandrel 9, support 11, lower position switch 10, upper limit position switch 12.Motor 7 and support 11 are for fixedlying connected, and screw mandrel 9 is fixedlyed connected with 7 in motor, and slide block 8 and screw mandrel 9 be for flexibly connecting, and lower position switch 10, upper limit position switch 12 and support 11 are for fixedlying connected.Its course of work is: drive screw mandrel 9 and rotate when motor 7 is just changeing, slide block 8 can up move along screw mandrel 9, and when slide block 8 rises to the position of upper limit position switch 12, motor 7 will stop; When motor 7 counter-rotating, slide block 8 can move down along screw mandrel 9, and when slide block 8 drops to the position of lower position switch 10, motor 7 will stop.Tractor will drive the light intensity check-out console 2 of fixedlying connected with slide block 8 and moves like this.
