Abstract

PROBLEM TO BE SOLVED: To provide a lamp for vehicles, which condenses light from low emission light source and has a light-emitting portion taking up a small space. SOLUTION: Disclosed herein is a lamp for vehicles E, which condenses and emits light from a plurality of low emission light emitting diodes 10 that are disposed closely on a holder 11. Light from the respective light emitting diodes 10 is condensed in condenser lenses 22 that are disposed opposite to the respective light emitting diodes 10. Disposed adjacent to the condenser lenses 22 are light guide holders that maintain ends of optical fibers 30 opposite to the respective condenser lenses 22. The optical fibers 30 are tied into a bundle and extended to a lens 40 disposed at their light-emitting end. As a result, weak light from the light emitting diodes 10 is condensed into strong light and drawn to the light-emitting end, so that it can be used as auxiliary light. Also, a space occupied by the light-emitting end can be reduced, so that it can be disposed in a free manner.

As a result, according to the vehicular lamp of the present invention,
Even light from a light source with a small amount of light is independently converged by the light converging member, the converged light is guided to another part by the light guiding member, and the ends of the light guiding member located in the other part are bundled. Since the light source is opposed to the emission end member, the number of light sources can be reduced even if the amount of light of one light source is small. Strong light is emitted from the member. Also,
Since the light from the light source is converged and emitted, it is not necessary to set the light distribution control for each light source, and the appearance is improved because the light source looks like a single light source.
