Patent ID: 7850314

Claim:
A light-emitting module comprising: a single reflector having a plurality of concave reflection surfaces each having an outer shape partially notched at a boundary thereof with the adjacent concave reflection surface; and light emitters in a same number as a number of the concave reflection surfaces, each of the light emitters adapted to emit light toward the concave reflection surface; the light emitters each including: a light-emitting diode chip arranged at or near a focal position of a respective one of the concave reflection surfaces, the light-emitting diode chip adapted to emit light toward the respective concave reflection surface; and an electrode lead, to which the light-emitting diode chip is fixed, the electrode lead being opposite the concave reflection surface with respect to the light-emitting diode chip, a size of the electrode lead in a direction parallel to an optical axis of the respective concave reflection surface being larger than a smallest size thereof on a plane perpendicular to the optical axis of the respective concave reflection surface, the electrode lead having a plate shape elongated in a direction perpendicular to the optical axis and extending away from the light-emitting diode chip, and the major surfaces of the electrode lead being exposed to air, wherein a ratio y/x is 2 to 6 where y is a width of each of the respective electrode leads as the size in the direction parallel to the optical axis of the corresponding concave reflection surface and x is a thickness as the smaller size on the plane perpendicular to the optical axis of the corresponding concave reflection surface.
