摘要： PROBLEM TO BE SOLVED: To precisely adjust the sight of a headlight by a method wherein a frame which is movable with reference to an automobile is installed, a housing which can be adjusted in the longitudinal direction is installed and a control device is controlled properly. SOLUTION: A housing 52 is provided with a lens by which a beam of light from a headlight can be focused on a screen, and the beam of light is reflected by a camera as an optical image sensing means. When the screen of a display device 88 is selected by either a selection switch of a push button 90 on a control board 86, its CPU starts a motor 24 for the X-axis direction and a motor 44 for the Y-axis direction by the push button 90 on the control board 86, and it moves a movable mounting rack 30 in such a way that the rack can be positioned in the desired longitudinal direction and the desired horizontal direction with reference to the automobile headlight arranged so as to be adjacent to a pedestal 12. Then, the automobile headlight is arranged or aligned precisely with reference to the lens in the housing 52.

摘要： PURPOSE: To provide an adjusting method in which the optical axis of a Z beam-type headlight is adjusted properly. CONSTITUTION: The position of the center of gravity G of a region B in which the irradiation pattern of a headlight irradiating a screen is at a prescribed illuminance or higher is found. An isoilluminance curve C which has an illuminance at a prescribed ratio with reference to the illuminance of the center of gravity G is found. When the ratio is set properly, the isoilluminance curve C agrees nearly with the light and shade boundary line of the irradiation pattern. The position of an inflection point Ca on the isoilluminance curve C in a stepped region a3 in which the stepped part of the light and shade boundary line exists is found, and the expression of a horizontal line Cb which is approximate to the isoilluminance curve C in a horizontal region a1 in which the horizontal part of the light and shade boundary line exists is found. The inflection point Ca is used as a reference in the horizontal direction when an optical axis is to be adjusted, the horizontal line Cb is used as a reference in the vertical direction when the optical axis is to be adjusted, and the optical axis of the headlight is adjusted.

摘要： PURPOSE: To determine the position of a bright/dark border line stably based on a data, where the difference of brightness is enhanced and noise is canceled, obtained by accumulating actually measured data. CONSTITUTION: Irradiation pattern of a headlight is picked up and scanned across a dark part D and a bright part B to obtain illuminance level variation curves, as shown by curve C1, at a plurality of points for every specified interval. The level variation data is accumulated in the direction in parallel with the bright/dark border line thus obtaining a curve CN. A line passing through the position BP of an inflection point P on the curve CN and extending at an inclination equal to a preset angle of the bright/dark border line is determined as a bright/dark border line.

摘要： PURPOSE: To provide an adjusting method in which an optical axis can be adjusted automati cally even when the optical axis is coupled to an adjusting screw for the up and down direc tion and an adjusting screw for the right and left direction in any order by a method wherein the relationship between the optical axis adjusting direction and the optical-axis moving direction of the adjusting screws which couple a driver unit is discriminated automatically. CONSTITUTION: A headlight HL for a car A in a definite position is turned on, an irradiation pattern B on a screen 2 is imaged 3, and an image processor 4 measures the optical axis of the headlight HL. It is measured in such a way that the middle point C of virtual light- source images L, R at a time when the headlight HL is situated in a prescribed position is measured in advance so as to be stored 4.and that the deviation of the headlight HL is detected as the deviation of the middle point C. In addition, the center of gravity G of the pattern B is measured and adjusted as a point in which the optical axis agrees, and the optical axis is put into an accepted range WP. Then, a driver unit 9 is coupled, by a manual operation, to one out of the adjusting screw for the up and down direction and the adjusting screw for the right and left direction of the headlight HL, the unit 9 is controlled 4 on the basis of a. measured result, and the direction of the optical axis is adjusted. The other direction is adjusted in the same manner. Consequently, even when the unit 9 is coupled in any order, the optical axis can be adjusted automatically.

摘要： PURPOSE: To measure, with high accuracy, a glare zone which agrees with the sense of a human being in a method in which the glare zone of headlight light is measured on the basis of the irradiation pattern, of headlight, which appears on a screen arranged in front of the headlight. CONSTITUTION: An illuminance distribution is measured along a scanning line, in the horizontal direction or the up and down direction, which passes a region at a prescribed illuminance or higher in an irradiation pattern. Intersecting points E of a tangent line CL passing a highest illuminance point C in illuminance distribution curves (a), (b) with tangent lines DL passing inflection points D in the rise region of an illuminance are computed. On the basis of the intersecting points E, the boundary point of a glare zone on the scanning line is found.

摘要： PURPOSE:To constantly adjust the distance between the head lamp of a motorcycle and a head lamp testing machine in accordance with the model of the motorcycle by mounting the head lamp testing machine on a mobile base which can be brought nearer to and separated from a front wheel supporting base. CONSTITUTION:The attitude of a motorcycle V is stabilized after the front and rear wheels WF and WR of the bicycle V are respectively placed on front wheel placing drums 711 and 712 and rear wheel placing drums 191 and 192. While the motorcycle V is kept in such a state, the mirror of an instrument body 101 is positioned against the front face of a head lamp L by moving a head lamp testing machine 10 mounted on a base body 103 leftward and rightward against the motorcycle V by moving the base body 103 leftward and rightward along rails 99. Then, the distance between the head lamp L and mirror of the testing machine 104 is adjusted by moving a mobile base on rails 94, namely, the testing machine 104 forward and backward against the motorcycle V by means of a moving motor 96. Therefore, the distance between the head lamp L and the mirror of the machine 104 can be accurately fixed (for example, to 3m) even when the distance between the front wheel WF and head lamp L varies depending upon the model of the motorcycle.

摘要： PURPOSE:To measure the optical axis and illuminance of a headlight in a short time without using any illuminance meter by simultaneously measuring the illuminance at the time of measuring the optical axis of the headlight. CONSTITUTION:A translucent screen 3 is provided in front of a headlight HL and the picture of the irradiating pattern of the headlight HL is taken with a CCD camera and, at the same time, the stop value of the camera 4 is detected. On the other hand, the relation between the output of the camera 4 and the illuminance of the headlight HL is stored in advance by changing the stop value of the camera 4 and the absolute illuminance of the headlight HL at every picture element is found from picture data P and stop value data F.

摘要： PURPOSE:To improve visibility and visibility to be viewed, and improve illuminating characteristics by changing and controlling either one of a diffusion range of a radiating light flux or a lamp color according to information of a travel condition detecting means. CONSTITUTION:A coloring globe 23 is formed of cylindrical chromatic transparent glass, and approaches/retreats freely to/from an exterior fitting position or a front position along the optical axis L relative to a bulb 9. The globe 23 is driven by an actuator, and colors or decolors emitting light of the bulb 9. Here, a diffusion range of a radiating light flux passing through lenses 11 and 13 is converged or diffused in the front position of the globe 23 to the bulb 9. The diffusion range of the radiating light flux passing through the lenses 11 and 13 can be also conversed or diffused in the exterior fitting position of the globe 23 to the bulb 9. Then, a desired radiating light flux can be obtained according to a travel condition of wheels, and can be also switched to another diffused light distribution by control driving.
