摘要： Lighting device includes a light source and a light guide body that has an in-coupling portion that collects the light, a propagating portion that carries the collected light, and an out-coupling portion, which has a central light emitting portion with a central exterior surface, an extended light emitting portion with a proximal reflecting surface and an extended exterior surface, and a deflecting element. The central light emitting portion guides a first light portion emerging from the propagating portion towards the central exterior surface where it is emitted. The deflecting element guides a second light portion emerging from the propagating portion towards the extended light emitting portion, which reflects the second light portion towards the extended exterior surface where it is also emitted. The central surface generates light to satisfy light distribution standards while the addition of the extended light emitting areas assures that a minimum light emitting area is satisfied.
