Abstract (en)

[origin: EP2543926A2] The optical head (10) has semiconductor light source (12) that emits light to generate predefined light distribution with bundles of light-dark boundary (42). A lighting unit couples a portion of emitted light. The reflecting boundary surfaces performs total reflection of injected light, while light output surface decouples injected light, after total reflection on one boundary surface. The boundary surfaces are divided into several regions (34) assigned to defined point of light source luminous surface. The regions are formed such that light-dark boundary is generated. An independent claim is included for light module.
