    摘要： An LED lamp (50) includes a plurality of LEDs (52) and a pillar (54) that is defined by a polygonal cross-sectional shape and includes a plurality of lateral surfaces on which the plurality of LEDs (52) are disposed. Additionally, a pillar radius ratio (D) is set to fall in a range of greater than or equal to 3.73% and less than or equal to 18.25%. The pillar radius ratio (D) is defined as a dimensional ratio of a pillar radius (S) to a radius of an opening (22) of a reflector (12) made in shape of a bowl. The pillar radius (S) is defined as a distance from a center point (C) of the pillar (54) to each of the plurality of lateral surfaces. The reflector (12) includes a reflective surface (20) on an inner side thereof so as to reflect rays of light emitted from the LED lamp (50), and causes the rays of light reflected by the reflective surface (20) to be irradiated from the opening (22).

    摘要： A subject is to provide a reflector 12 for use in a light emitting device 10, and a light emitting device 10 using the same, which are capable of significantly improving a uniformity ratio of light intensity on an irradiation target surface A when light emitted from a plurality of directional light sources 26a, 26b is reflected thereon.
    To solve the above subject, micro reflector segments 29 are protruded from a concave reflecting surface 20 of the reflector 12 in multiple stages and in multiple radial columns, the micro reflector segments each having a convex curved surface 29a which is defined by a locus of a circular arc moved in parallel in a radial direction of the concave reflecting surface 20; and a radius R of the convex curved surface 29a is set, in each of the reflection regions S1, S2, to be smaller when the convex curved surface 29a is positioned closer to a point P on which light emitted from each of the directional light sources 26a, 26b and traveling on the light axis L is incident, and is set to be larger when the convex curved surface is positioned more distant from the point P.
