Embodiment Construction

[0044] In order for lighting devices using semiconductor light sources (such as headlights or taillights in motor vehicles) to produce the prescribed light-technical functions, it is important that the light-emitting area of ​​the semiconductor light sources of the lighting device be at a height relative to the rest of the optical system Precise positioning and orientation (position correctly adjusted). The semiconductor light sources are designed, for example, as light-emitting diodes (LEDs). It has a light-emitting region which, for example, comprises a converter material which, when irradiated by the LED with blue light, emits yellow light which mixes with the blue light of the LED to form white light.

[0045] The invention allows a particularly precise positioning of the circuit carrier relative to the optical system of the lighting device. The optical system 20 may comprise a reflector of a lighting device of a motor vehicle, such as a motor vehicle headlight or a motor...

Abstract

The invention relates to a method for arranging a circuit carrier (30) of a lighting device of a motor vehicle (30) comprising at least one semiconductor light source (32) at a defined position relative to an optical system (20). In order to improve the positioning accuracy of the semiconductor light source (32) relative to the optical system (20), it is proposed to construct a stop surface (400) on the optical system (20), the stop surface has stop ribs (402) standing at intervals from each other ), the circuit carrier (30) rests on the stop rib with a defined support area (404). The stop ribs ( 402 ) are designed in a special manner so that the varnish applied to the optical system ( 20 ) can run away from the ribs ( 402 ) to the greatest extent possible.

Description

technical field [0001] The invention relates to a method for arranging a circuit carrier and a lighting device for a motor vehicle having a circuit carrier arranged according to the method according to the invention. Background technique [0002] In order for lighting devices for motor vehicles (e.g. headlights or taillights) to produce the specified light-technical functions, it is important that the light-emitting areas of the semiconductor light sources (LEDs) used be positioned and aligned with a high degree of precision in relation to the rest of the light system . WO 2014 / 1535761 discloses a camera-controlled high-precision placement of semiconductor light sources on a circuit carrier. The light-emitting regions of the LEDs are detected and, depending on their position, the LEDs are placed on the circuit carrier and then electrically contacted. Thereafter, in the following assembly step, the circuit carrier and the LEDs mounted thereon are arranged in the optical sys...
