Abstract: A wavelength conversion device includes a light source for emitting light having a predetermined wavelength in a wavelength region from ultraviolet light to visible light, a phosphor layer for performing wavelength conversion on light which is emitted from the light source and incident on an incidence face, and an optical member which is arranged between the light source and the phosphor layer, splits and separates light emitted from the light source and emits the split and separated light beams to the incidence face of phosphor layer.

Abstract: An optical lens includes: a first lens surface which defines a space for housing a light emitting diode (LED) light source; a second lens surface formed in a convex shape; and a third lens surface formed continuously from a rear edge portion of the second lens surface, which is on a side opposite an illumination target side. The first lens surface includes a first light-entering surface through which a portion of light from the LED light source enters, and a second light-entering surface through which another portion of the light enters. The third lens surface totally reflects, to a substrate, at least a portion of the light. An angle between the third lens surface and a principal surface of the substrate on a virtual plane which includes an optical axis is smaller than an angle between the second light-entering surface and the principal surface on the virtual plane.
