Abstract:
An LED light-emitting element having reduced the occurrence of illuminance unevenness is provided. A light-emitting element comprising a substrate, an LED element mounted on the substrate, a phosphor resin arranged on the substrate so as to seal the LED element and having an emission surface from which light based on light emitted from the LED element is emitted, a reflective resin arranged around the phosphor resin; and a reflecting frame having an opening and at least part of which is arranged on the reflective resin, wherein the reflective resin is arranged directly under the reflecting frame and on the side surface of the phosphor resin, the ratio of the area of the emission surface to the area of an inside area of the reflecting frame is set to 80% or higher, and in the inside area of the reflecting frame, the reflective resin is exposed around the emission surface.
