1. A lamp for a vehicle, comprising:
- a lamp unit comprising a lamp body, a front lens, and a plurality of light-emitting diodes juxtaposed at predetermined intervals; and
a plurality of light control parts each comprising nine prisms arranged in a 3×
3 matrix formed in an inner wall of said front lens in correspondence to each of the respective light-emitting diodes to direct output light beams of said light-emitting diodes in a predetermined direction, a central one of said nine prisms of each of said light control parts facing the respective light-emitting diode, and each of the four prisms adjacent said central one of said nine prisms having a step along inner edges thereof.

Abstract
A stop lamp for a vehicle, such as a stop lamp adapted for mounting on a rear spoiler of an automobile, having an improved efficiency of light utilization. The lamp includes a lamp body, a front lens, and a plural number of light-emitting diodes juxtaposed at predetermined intervals. Light control parts are formed in the inner wall of the front lens for directing the light output from the light-emitting diodes in predetermined directions. Each light control part is composed of nine prisms arranged in a 3×3 matrix. The central one of the prisms faces a respective one of the light-emitting diodes.
