Positioning device for e.g. elliptic lighting module, with respect to case of optical unit of vehicle, has controlling unit determining instructions for actuators to allow placement of lighting module with respect to element

摘要

The device (D) has three actuators i.e. jack, varying length according to instructions. An end (E11) of the each actuator is mounted at rotation on a selected part of a lighting module (ME), and another end (E12) of the actuator is mounted at rotation on a selected part of a fixed element (EF). A controlling unit (MC) determining the instructions for the actuators to allow placement of the lighting module with respect to the fixed element in a chosen isostatic position. The controlling units are arranged to determine the instructions to move the lighting module with respect to a site axis. An independent claim is also included for an optical unit, comprising a fixed element.
