PURPOSE: To obtain a laminated light emitting diode in which a light emitting color does not become different according to a viewing direction by a method wherein a first light emitting diode which reflects light emitted by a light emitting element and a second light emitting diode which transmits light emitted from the first light emitting diode are arranged in the light radiating direction of the first light emitting diode. CONSTITUTION: Light emitted by a light emitting element 1a for a first light emitting diode is reflected, by a concave reflection face 5b, in parallel to the central axis, and it then reaches a front plate 6 so as to be radiated to the front from a radiation face 7a. Light reaching a concave reflection face 5a from a light emitting element 1b for a second light emitting diode is reflected, by the reflection face, in parallel to the central axis, and it reaches the front plate 6 so as to be radiated to the front from the radiation face 7a. The light, from the concave reflection face 5a, which is emitted by the light-emitting element 1a and the light, from the concave reflection face 5b, which is emitted by the light emitting element 1b are radiated in the same direction from the same place of the front plate 6. As a result, colors are mixed and become visible even when the front plate 6 is not formed to be light diffusive. |
