摘要： In an automotive headlamp, a light-emitting module is configured such that a light-emitting element and a control circuit unit for controlling the lighting of the light-emitting element are structured integrally with each other. A control circuit unit in a position anterior to the light-emitting element in a lamp unit is located below a shade section so that the control circuit unit can be clear of the path of light used to form a low beam light distribution pattern of the light emitted by the light-emitting element. In this setting, the light-emitting element is so located that a main optical axis Ax2 is perpendicular respect to an optical axis Ax1 of the lamp unit and that a light-emitting portion of the light-emitting element protrudes higher than the control circuit unit in the direction of the main optical axis Ax2.

摘要： A blade receives light emitted from a light source and repeats a predetermined periodic motion to scan the front of a vehicle with reflected light of the emitted light. A position detector generates a position detection signal S4 indicating a timing at which a predetermined reference point of the blade passes a predetermined position. Based on the position detection signal S4, a period calculator calculates a period Tp of the periodic motion of the blade. A light intensity calculator receives light-distribution-pattern information S3 to be formed in front of the vehicle and calculates light intensity to be generated by the light source at each time based on the position detection signal S4 and the period Tp. A driver turns on a semiconductor light source so as to obtain the light intensity calculated by the light intensity calculator at each time.

摘要： A vehicle lamp control system is provided which can not only restrict a semiconductor light emitting element from being deteriorated or damaged by sunlight and but also maintain an illumination efficiency of the semiconductor light emitting element. The vehicle lamp control system includes a projection lens, semiconductor light emitting elements disposed near a rear focal point of the projection lens and emit light towards the projection lens, a movable shade which can move between a shading position where the movable shade cuts off light emitted from the semiconductor light emitting elements to be incident on the projection lens and a non-shading position where the movable shade does not cut off light emitting elements to be incident on the projection lens, and a headlamp control unit which executes a control in which the movable shade is moved to the shading position with the semiconductor light emitting elements left switched off.
