Vehicular lamp and light source module
A vehicular lamp used in an automobile, includes: a light source module for generating light; and an optical member for directing the light generated by the light source module forward. The light source module includes: a semiconductor light-emitting element or device for generating light; a fluorescent member for emitting light in accordance with the light generated by the semiconductor light-emitting element, the fluorescent member covering a surface of the semiconductor light-emitting element; and a light-blocking member, formed to be opposed to the semiconductor light-emitting element with the fluorescent member sandwiched therebetween and cover a side of the semiconductor light-emitting element and a part of the fluorescent member, for blocking a part of the light generated by the semiconductor light-emitting element and a part of the light emitted by the fluorescent member.
1. A vehicular lamp used in an automobile, comprising:
a light source module operable to generate light; and
an optical member operable to direct the light generated by said light source module forward, wherein said light source module includes:
a semiconductor light-emitting element operable to generate light;
a fluorescent member, covering a surface of said semiconductor light-emitting element, operable to emit light in accordance with said light generated by said semiconductor light-emitting element; and
a light-blocking member, formed to be opposed to said semiconductor light-emitting element with said fluorescent member sandwiched therebetween and cover a side of said semi-conductor light-emitting element and a part of said fluorescent member, operable to block a part of said light generated by said semiconductor light-emitting element and a part of said light emitted by said fluorescent member.
2. The vehicular lamp as claimed in claim 1 , wherein said optical member forms at least a part of a cut line that defines a boundary between a bright region and a dark region in a light distribution pattern of said vehicular lamp by projecting at least a part of a shape of an edge of said light-blocking member.
3. The vehicular lamp as claimed in claim 1 , wherein said light-blocking member is formed to overlap said fluorescent member.
4. The vehicular lamp as claimed in claim 1 , wherein said light source module includes a plurality of semiconductor light-emitting elements, and
said light-blocking member is provided commonly to said plurality of semiconductor light-emitting elements in such a manner that said light-blocking member covers a side of each of said plurality of semiconductor light-emitting elements.
5. The vehicular lamp as claimed in claim 1 , wherein said light-blocking member is formed to entirely cover two sides of said semiconductor light-emitting element, the two sides being adjacent to each other.
