<p>PROBLEM TO BE SOLVED: To provide a vehicle head lamp which permits miniaturization and light weight in the vehicle head lamp using an LED light source.SOLUTION: A vehicle head lamp includes a plurality of LEDs as a light source and an inner lens arranged on the front side of the plurality of LEDs. Therein, a curved difference part which protrudes toward the arrangement side of the LED (rear side) and reduces protrusion amount toward the center part from a lower part of the inner lens is formed on a back surface of the inner lens, thereby, diffusion of light of the LED passing through the difference part to the upper direction is suppressed and, even when the plurality of LEDs are used, light is applied within an appropriate range, therefore, the light source can be effectively utilized and miniaturization and light weight of the vehicle head lamp is permitted.</p> |
