PROBLEM TO BE SOLVED: To provide a layer-built light emitting diode which effectively radiates the light emitted from a light emitting element to the outside and is so observed that the whole reflecting surface generates a light when viewed from the front, by forming two kinds of mirror surfaces constituted by arranging a dichroic mirror in the central part of a concave optical surface of the light emitting diode, and forming fine-strip shaped vapor deposition and metal plating such as aluminum and silver in the peripheral part. SOLUTION: This layer-guilt type light emitting diode is provided with light emitting elements 11, 21, a lead part supplying electric power to the light emitting elements 11, 21, light transparent materials 14, 24 sealing the light emitting elements 11, 21, and optical surfaces 15, 25 facing the light emitting surfaces of the light emitting elements 11, 21. The optical surfaces 15, 25 facing the light emitting elements 11, 21 reflect lights generated from the light emitting elements 11, 21. A light emitting diode 10 as a first light source which transmits light from below is arranged at least in the light radiating direction of a second light source. The central part of the optical surface which faces the light emitting element 11 of the light emitting diode 10 as the first light source is a dichroic mirror surface which reflects the light from the light emitting element 11 of the light emitting diode 10 as the first light source, and transmits the light radiated from the second light source arranged in the lower part. The peripheral of the dichroic mirror surface is a macroscopically semi-light-transmitting metal reflecting surface. |
