Document Type and Number:
WIPO Patent Application WO/2018/025496
Kind Code:
A1
Abstract:
An illumination apparatus (300) has: a surface (310) to be irradiated; and light-emitting devices (200) that are each obliquely arranged directly above the surface (310). The light-emitting devices (200) each have a light-emitting element (210) and a luminous flux control member (100). The luminous flux control member (100) distributes light emitted from the light-emitting element (210) in directions above and below the optical axis (OA) of the light-emitting element (210). The absolute value of the angle (θ1) formed between the optical axis (OA) and the optical axis of the light directed upward is smaller than the absolute value of the angle (θ2) formed between the optical axis (OA) and the optical axis of the light directed downward.
