Abstract (en)
[origin: EP3680546A1] It is an object of the present disclosure to provide an illumination device which enables the degree of design freedom of a housing to be increased. An illumination device includes: a housing (2); a light source (80) provided in the housing (2); and an optical member (9) having an incidence plane (911) via which light output from the light source (80) enters the optical member (9). The housing (2) or the optical member (9) includes an exit plane (94) from which light passing through the optical member (9) goes out of the housing (2). The exit plane (94) has an area (S<sub>2</sub>) smaller than an area (S<sub>1</sub>) of the incidence surface (911).
