自動車両用投光装置のための照明装置

Document Type and Number:

Japanese Patent JP6931430

Kind Code:

B2

Abstract:

The invention relates to a light module for a motor vehicle headlamp comprising at least one light source (2) and at least one optical imaging system (3) which images light generated by the at least one light source (2) into a region in front of the light module (1) in the form of at least one light distribution of a predefined type. The optical imaging system 93) comprises an entry optical unit (31), an exit optical unit (32), and at least one beam-shaping device (33), which beam-shaping device (33) is arranged between the entry optical unit (31) and the exit optical unit (32). The entry optical unit (31) is designed to capture the light generated by the at least one light source (2) and to conduct it in the form of a plurality of light beams in the direction of the beam-shaping device (33), the beam-shaping device (33) is designed to shape the plurality of light beams to form at least one intermediate image of a predefined type, and the exit optical unit (32) is designed to project the at least one intermediate image of a predefined type in the form of at least one light distribution of a predefined type into a region in front of the light module (1). The beam-shaping device (33) is formed as a continuous layer extending in a plane perpendicular to the optical axis (OA) of the optical imaging system (3), which continuous layer is controllable in respect of its transparency. In addition, the total amount of light penetrating from the entry optical unit (31) to the exit optical unit (32) can be influenced by adjusting the transparency of the continuous layer.
