To improve the sense of connection between a fixed-side lamp unit and a movable-side lamp unit. A vehicle lamp includes; a fixed-side unit, and a movable-side unit, the fixed-side unit has: a first light source; a first light guide body; and a first outer lens having a first front surface part, and a first leg part, the movable-side unit has: a second light source; and a second light guide body; and a second outer lens having a second front surface part, and a second leg part, the second leg part has a light control surface, and the light control surface performs control such that light emitted from at least one of the first light source and the second light source and incident on the light control surface passes through inside of the second leg part and is emitted from a front surface side of the second leg part.

Vehicle lamp

Problem: To provide a vehicle lamp fitting in which regularity of the strength or weakness of the emitted light is maintained and deterioration of appearance is suppressed. Solution: A vehicle lamp fittingcomprises a light guidewhich guides light from an LED light sourceand an LED light source, the light guidehaving entrance surfaces, emission surfaces Rto R, and an internally reflecting surfacewhich causes light that has entered through the entrance surfacesto be reflected, and the internally reflecting surfacecomprises a reflecting surfacewhich is provided in a first regionand which emits light from the LED light sourcein a forward direction, a reflecting surfacewhich is provided in a second regionand which emits light from the LED light sourcein the forward direction, and a reflecting surfacewhich is formed in a third regionbetween the first regionand the second regionand which limits the light intensity with which light from the LED light sourcesis emitted in the forward direction from the emission surface R

Vehicle lamp fitting

In existing lamp unit for vehicles, the light from the semiconductor light source can not be effectively used. In the present invention, a planar reflect surface () is arranged between the projection lens () and its focus (FL) in such a way that the planar reflect surface () intersects the light axis (Z-Z) of the projection lens (); a light shutout member () is arranged between the semiconductor light source () and the projection lens (); the light shutout member () is provided with supplemental reflect surfaces (-) reflecting the light (L) from the semiconductor light source () toward the shade (). As a result, the light (L) from the semiconductor light source () can be effectively used.

Lamp unit for vehicles

In existing lamp unit for vehicles, the light from the semiconductor light source can not be effectively used. In the present invention, a shade () is arranged between the second focus (F) of a first reflect surface () and a semiconductor light source (), for cutting off a portion of the reflected light (L) emitting from the semiconductor light source () and reflected by the first reflect surface (), and using the remaining reflected light (L) to form a predetermined distributed light pattern (P) having the cutoff lines (CL); a light shutout member () is provided with the fourth part () of the supplemental reflect surface for reflecting the light (L) from the semiconductor light source () toward the shade (); a through hole () is arranged on the shade () for the reflected light (L) from the fourth part () of the supplemental reflect surface illuminating therethrough toward the planar reflect surface (). As a result, as a distributed light pattern Pfor a overhead sign, the light (L) from the semiconductor light source () can be effectively used.
