Description
Technical Field
The utility model relates to a device that distance light function of vehicle headlamps detected, the device that uses when especially the car of two lamp systems carried out the headlamp detection.
Background
The headlamp detection technology is a technology for detecting the light emission intensity of a headlamp of an automobile (commonly called "automobile headlamp") and the irradiation direction of a light beam. The method can detect whether the headlamp is burnt out, stained and abnormal in irradiation angle and correct the headlamp in time. To achieve the desired performance.
The automobile headlamp detection is an important item for detecting the safety performance of the automobile. The main parameters for headlamp diagnostics are the luminous intensity and the beam irradiation position. When the luminous intensity is insufficient or the light beam irradiation position is inclined, the sight of a driver driving at night is unclear or the driver coming from the head-on is dazzled, so that the driving safety is greatly influenced. Therefore, the light emission intensity and the beam irradiation position of the headlight should be detected and corrected periodically.
The currently known automobile headlamp detection method generally uses a screen method, and three vertical lines and three horizontal lines need to be drawn on an irradiation screen during detection, wherein a middle vertical line V-V is aligned with a longitudinal center vertical plane of a detected vehicle. Vertical lines VL-VL and VR-VR at two sides are vertical lines of the reference centers of the headlamps at the left and right sides of the vehicle to be detected respectively. During detection, headlamps on two sides are required to be respectively covered, a non-detection headlamp on the other side is firstly covered, then a low-beam switch of the headlamp is turned on, the low-beam cut-off line corner or the light beam center of the headlamp which is not covered is required to fall on the intersection point position of the lower horizontal line and the VL-VL or VR-VR line in the figure, otherwise, the light beam irradiation position is inclined. The deflection direction and deflection amount can be directly measured on the screen. In the same manner, the low beam irradiation position of the other side headlamp is detected. According to the detection standard, when the irradiation position of the headlight light beam is detected and adjusted, the far and near double-beam lamps are mainly used for detecting and adjusting the low-beam light beam. For a high beam single beam headlamp, the irradiation position of the high beam is detected. Its beam center should fall at the intersection of the middle horizontal line and the VL-VL or VR-VR line.
Although the detection of the headlight by the screen method is simple and easy, only the irradiation position of the light beam can be detected, and the light emission intensity cannot be detected. And the preparation process is loaded down with trivial details, and for the detection that adapts to different motorcycle types, all need change the screen when examining at every turn, to the work of the repeated shading cloth or the light screen of changing of vehicle under examination, it is too much to consume manpower and materials resources, and detection efficiency is low.
