<p>The headlight has a light source (1) e.g. LED, for emitting rays of light (L1, L2) in a spatial area, and an optical concentrator (2) e.g. compound parabolic concentrator and compound elliptical concentrator, provided with a light input and a light output (22). The light is separated from the light source and the concentrator. Reflectors (3, 4) are arranged such that a part of the light emitted from the light source meets and reflects on the reflectors, and another part of the light is made available after the reflection.</p> |
