Abstract
A lightguide component for light emission devices has a first principal face and a second principal face at an opposite side from the first principal face. The lightguide component for light emission devices includes: a lightguide layer including a light-receiving portion to receive light emitted from a light source, a third principal face at the first principal face side, and a fourth principal face at the second principal face side; and a light distribution controlling structure having a plurality of internal spaces, the plurality of internal spaces creating interfaces to direct a portion of the light propagating in the lightguide layer toward the first principal face via total internal reflection. In a plan view a first region in which the light distribution controlling structure is present and a second region in which the light distribution controlling structure is not present are disposed so as to define a predetermined design.
