High beam light-emitting intensity detecting method of vehicular head light detector and detecting mechanism thereof

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 [0001] The invention belongs to a method for detecting the luminous intensity of a high-beam light beam of a vehicle headlight detector and a detection mechanism thereof. Background technique [0002] At present, the detection method of the high-beam luminous intensity of the general vehicle headlamp tester is to use the luminous intensity at the center of the high-beam beam of the headlamp as the luminous intensity of the headlamp. For headlamps with poor light distribution, there is a certain error between the luminous intensity of the center of the beam and the strongest point of the luminous intensity of the beam, so there is also a certain error in detecting the luminous intensity of the high beam of the vehicle headlamp with the above method. Contents of the invention [0003] The object of the present invention is to provide a vehicle headlamp detector high beam luminous intensity detection method and its detection mechanism which can detect the ligh...
