<P>PROBLEM TO BE SOLVED: To make dimensions of an optical axis direction and a vertical direction (height direction) small in a vehicle lamp. <P>SOLUTION: The vehicle lamp is provided with a concave surface reflector 11 reflecting light emitted from an LED 12, a flat surface reflector 13 reflecting light reflected at the concave surface reflector 11, and a convex lens 14 projecting the light reflected at the flat surface reflector 13 toward front PD of the vehicle lamp. The LED 12 is arranged at a first focal point F1 of the concave surface reflector 11, after a part of the light emitted from the LED 12 is reflected at the concave surface reflector 11, it is condensed at a second focal point F2 of the concave surface reflector 11. A straight line Z2 connecting between the first focal point F1 and the second focal point F2 vertically crosses to an optical axis Z1 of the convex lens 14, and then, the vehicle lamp is used in a state in which the straight line Z2 and the optical axis Z1 are horizontal, respectively. <P>COPYRIGHT: (C)2010,JPO&INPIT |
