Illumination apparatus

An illumination apparatus comprising a light source unit which emits primary light, and an optical unit which functions when the primary light emitted from the light source unit is applied to the optical unit,

• the light source unit comprising a primary light emitting portion which emits the primary light to the optical unit,
• the optical unit comprising:
• a primary light entrance portion which is optically connected to the primary light emitting portion and which the primary light emitted from the primary light emitting portion enters;
• a light converting member which is provided apart from the primary light entrance portion, the light converting member converting the optical characteristics of the primary light entering from the primary light entrance portion when the primary light is applied to the light converting member, the light converting member generating secondary light different from the primary light;
• an illumination light emitting portion which emits at least one of the primary light and the secondary light to an outside as illumination light;
• the central axis of the primary light emitted by the primary light emitting portion being referred to as an optical axis,
• the side of the primary light emitting portion in an optical axis direction being referred to as rearward,
• the side of the light converting member in the optical axis direction being referred to as frontward,
• a direction that intersects at right angles with the optical axis being referred to as sideward,
• a light transmitting member which is provided between the primary light entrance portion and the light converting member and which is also at least partly continuously provided from the primary light entrance portion to the illumination light emitting portion so that the primary light and the secondary light is transmitted therethrough;
• a reflecting portion which is provided on a circumferential surface of the light transmitting member including the light converting member and which reflects the primary light and the secondary light;
• and
• a reducing portion which is directly provided in the illumination light emitting portion or provided frontward to part of the illumination light emitting portion and which reduces the density of the primary light as the illumination light emitted from the illumination light emitting portion.
