Vehicle lamp having prismatic element
First Claim
1. A vehicle lamp includinga cup-shaped housing having a housing bottom for installation in an opening in a bodywork of a vehicle, a light exit opening in opposite relationship to the housing bottom, a light exit cover which covers over the light exit opening and closes the housing in an outward direction, at least one light emitting diode arranged in the interior of the housing and operable to emit a light beam the main axis of which extends substantially parallel with respect to the main axis of the housing which extends from the housing bottom to the light exit opening, and a prismatic element defined by first, second and third boundary surfaces and arranged in front of the at least one light emitting diode in such a way that said light beam emitted by the light emitting diode passes through the first boundary surface into the prismatic element and is at least partially reflected at the second boundary surface which is flat and is inclined with respect to the central axis of the light beam in such a way that the reflected part directly reaches the third boundary surface through which it exits the prismatic element and passes directly through said light exit cover in a direction which is disposed transversely with respect to the main axis of the housing but includes an angle of less than 90°
- therewith.

Abstract
A vehicle side-flashing lamp includes: a cup-shaped housing; a light exit opening opposite the housing bottom; and a light exit cover which covers the light exit opening. At least one light-emitting diode emits light outwardly at least partially at an angle which is large with respect to the main axis of the housing. A prismatic element, defined by first, second and third boundary surfaces, is arranged in front of the light-emitting diode in such a way that an emitted light beam passes through the first boundary surface into the prismatic element and is at least partially reflected at the second boundary surface, which is inclined with respect to the central axis of the light beam, in such a way that the reflected part issues from the prismatic element through the third boundary surface.

wherein the light exit cover is optically inactive to allow light to pass therethrough substantially unchanged.
