摘要： A light beam adjusting device includes a first optical deflection unit having a first light incidence face and a first light exit face, the first optical deflection unit being arranged to deflect light which is incident from the first light incidence face and which exits from the first light exit face at a first deflection angle. A second optical deflection unit has a second light incidence face and a second light exit face, the second light incidence face being arranged to face the first light exit face and including an array of prisms arranged to deflect the light exiting from the first light exit face at a second deflection angle. The light beam adjusting device obtains the desired deflection direction of the incident light beam by a compact structure providing two-stages of optical deflection units to achieve the deflection of an incident light beam.

摘要： The present utility model discloses a light guiding device and a vehicle lamp. The light guiding device includes a light guide medium component configured to allow light to be transmitted through it from one end thereof to another end thereof. A light guide fixing component is arranged on the light guide medium component and configured to fix the light guide medium component, wherein the light guide medium component and the light guide fixing component are both at least partly made of a transparent material. The light guide fixing component has a light directing portion configured to direct the light leaked from the light guide medium component into the light guide fixing component to exit the light guide fixing component away from a predetermined direction. Using the light guiding device and the vehicle lamp according to the present utility model can prevent light exiting the light guide fixing component from forming undesirable light spots in an undesirable direction.
