Claims

A lighting device comprising a first light source, a second light source, and a support member that supports the first light source and the second light source,
The support member is
Main surface,
A first surface perpendicular to the main surface and extending along the main surface;
A second surface facing away from the first surface behind the first surface, the second surface being perpendicular to the main surface and extending along the main surface;
The first light source is
A first wiring board disposed on the first surface and extending along the main surface;
A plurality of first light emitting elements disposed on the first wiring board so as to be along the main surface;
The second light source is
A second wiring board disposed on the second surface and extending along the main surface;
A plurality of second light emitting elements arranged on the second wiring board so as to be along the main surface,
The support member further includes:
A third surface facing obliquely with respect to the first surface and located on the main surface side of the plurality of first light emitting elements;
And a fourth surface that faces the second surface obliquely and is located closer to the main surface than the plurality of second light emitting elements.

In claim 1,
The first surface is an outer surface of a circular or polygonal cylinder;
The lighting device according to claim 2, wherein the second surface is an inner surface of a circular or polygonal cylinder.

In claim 2,
The support member has a conical or pyramid portion having a vertex below the main surface on the inner side of the fourth surface.

In any of claims 1 to 3,
A lighting device having a gap between a portion having the first surface and a portion having the second surface.

In any of claims 1 to 4,
The lighting device, wherein the first wiring board and the second wiring board have flexibility.

In any of claims 1 to 5,
The lighting device, wherein the first wiring board and the second wiring board are strip-shaped.

In any one of Claims 1 thru | or 6 .
The lower end of the third surface is located on the main surface side at a distance of half or less of the distance from the main surface to the first light emitting element,
The lower end of the fourth surface is an illuminating device located on the main surface side at a distance equal to or less than half of the distance from the main surface to the second light emitting element.
