1. An illumination unit for a vehicle comprising:
- a light emitting element;
an outer housing including an opening, on which the light emitting element is mounted;
a prism disposed between the light emitting element and the opening, for receiving light emitted from the light emitting element, the prism including a tip portion which is disposed at the opening, a body portion which continues from the tip portion and having a width larger than a width of the tip portion, a flange portion which continues from the body portion, having a width larger than the width of the body portion, and a stage at a boundary between the tip portion and the body portion, the stage having a surface orthogonal to a side surface of the body portion,wherein a portion of the light emitted from the light emitting element is reflected by the stage, away from the opening, so as not to be output through the opening.

9. An illumination unit for a vehicle comprising:
-
a light emitting element; an outer housing including an opening, on which the light emitting element is mounted; a cylindrical prism, formed of resin, disposed between the light emitting element and the opening, the prism including a first portion of a first radius, a second portion of a second radius, and a third portion of a third radius, wherein the first, the second, and the third radiuses are different from each other, so as to form a stage at a portion of the prism at which two of the first, the second, and the third portions meet, and wherein the first portion, the second portion and the third portion are entirely disposed between the light emitting element and the opening, and wherein light emitted from the light emitting element is reflected by the stage in a direction away from the opening so as not to be emitted through the opening, and wherein the stage has a surface orthogonal to a side surface of the second portion. - View Dependent Claims (10)
