Abstract: An optical device is provided. The optical device includes a first surface that defines a concave light incident surface facing a central axis and a light source; a second surface disposed opposite the first surface which is configured to reflect light incident on the concave light incident surface; and an inclined light exit surface between the first surface and the second surface. The second surface includes a concave first reflective portion curving toward the first surface, and a substantially flat second reflective portion which portion is interposed between a first reflective portion edge of the first reflective portion and an outer second surface edge of the second surface. The first reflective portion is configured to totally reflect light incident at a predetermined angle or more with respect to a top surface of the light source once to the light exit surface.

Abstract: A light source module includes a substrate, a plurality of light emitting devices disposed along a line on the substrate, and a lens. The lens extends in a long-axis direction in which the plurality of light emitting devices are aligned to cover the substrate and the plurality of light emitting devices, and has end sides opened at opposing ends of the lens in the long-axis direction. The lens has a first surface to which light from the plurality of light emitting devices is made incident, and a second surface allowing light made incident through the first surface to be radiated outwardly. The lens has a variable thickness, measured as a distance between the first surface and the second surface, in a cross-section of the lens along a plane orthogonal to the long-axis direction.
