摘要： An illuminating lens has a light entrance surface and a light exit surface. The light exit surface has a first light exit surface recessed toward a point on an optical axis A and a second light exit surface extending outwardly from the periphery of the first light exit surface. The first light exit surface includes a transmissive region located in the center of the first light exit surface and a total reflection region located around the transmissive region. The transmissive region transmits light that has been emitted from a starting point Q, which is the position of a light source on the optical axis A, at a relatively small angle with respect to the optical axis A. The total reflection region totally reflects light that has been emitted from the starting point Q at a relatively large angle with respect to the optical axis A.

摘要： A light exit surface of an illuminating lens has a first light exit surface and a second light exit surface. The first light exit surface is recessed toward a point on the optical axis, and the second light exit surface extends outwardly from the periphery of the first light exit surface. The first light exit surface has a transmissive region and a total reflection region.

A reflective layer is formed on a bottom surface that surrounds a light entrance surface and faces oppositely to the light exit surface. The reflective layer reflects light that has been emitted from the light source, totally reflected repeatedly at the light exit surface, and then reached the bottom surface.

摘要： A lighting device includes a light emitting element that emits a first colored light; a phosphor layer disposed on the light emitting element; and a lens part that is disposed so as to cover the light emitting element and the phosphor layer, and radiates light entering inside of the lens part so as to spread the light radially. The phosphor layer allows a part of the first colored light to transmit therethrough and converts another part of the first colored light into a second colored light having a wavelength longer than that of the first colored light. The lens part has: a base portion forming a light entrance surface through which the first colored light and the second colored light enter the lens part; and a diffraction portion forming a light exit surface through which the first colored light and the second colored light exit the lens part, the diffraction portion being configured so that a refracting power with respect to the second colored light is larger than a refracting power with respect to the first colored light.
