LIGHT SOURCE DEVICE AND LIGHTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a light source device capable of suppressing unevenness of color of light emitted from a light source device, even when there is unevenness of color in the light emitted from the light source components.

SOLUTION: The LED 110 (light source component) emits light toward a direction of an optical axis as a center. A lens (optical component) has a reflective surface 124. The reflective surface 124 reflects the light emitted from the LED 110. The shape of the reflective surface 124 coincides with a rotation surface in which a part of a parabola 426 (cone curvature) is rotated centered on a rotation axis 422 which is different from a symmetric axis 423 of the parabola 426 and is nearly parallel to the symmetry axis 423. The lens is arranged at a position in which the rotation axis 422 of the reflective surface 124 almost coincides with the optical axis of the LED 110.
