Lighting device for use as vehicle headlight, has light sources forming LED field and optical imaging elements exhibiting square cross section, where vertical side walls of elements of one of lines are bent

摘要

The device (B) has a set of semiconductor light sources e.g. LED, forming an LED field (1), where the sources are arranged linearly next to each other in a set of rows. A projection lens arrangement (4) is arranged in an optical path of light transmitted by the sources. An optical field (2) is arranged in the path between the sources and the arrangement. The optical field has a set of optical imaging elements (6) arranged like a matrix. The elements exhibit square cross section and vertical side walls of the elements of one of the lines are bent.
