Abstract: A bullet type light emitting diode lamp or a chip-type light emitting diode lamp includes a semiconductor light emitting element, and a plurality of fluorescent materials that absorb part or whole of light emitted from the semiconductor light emitting element, and emit fluorescence at a wavelength different from that of the absorbed light. The fluorescent materials include a phosphor of a CaAlSiN3 crystalline phase.
