Abstract
A lighting device includes at least one light source, and a lens. The lens directs light emitted from the at least one light source. The lens has a concave component with an inner bottom face and an inner face, the light emitted from the at least one light source being incident on the concave component, an emission face located on an opposite side from the concave component, and an outer face located to the side of the concave component. The inner face forms a convex face that faces toward inside of the concave component. The outer face reflects the light that has entered the lens through the inner face toward the emission face.
