Can be prevented from entering.
- the light shielding member 42 has its one end face from the outer periphery of the one end face of the taper light guide member to the light source side so as to suppress stray light when light from the light source is taken in from one end face of the taper light guide member. It overhangs to surround. That is, in the first light irradiation device 6, the gap between the lower end surface of the tapered light guide member 4, which is a tapered coupler that increases the directivity of the xenon emission light, and the opening plate 3 b facing the reflector 3 a is surrounded and covered.
- a light shielding member 42 provided with a light shielding wall in the direction of the adjacent light guide member as shown in FIG.

- stray light on the halogen light source 7 side is also shielded by the outer peripheral side surfaces other than the one end surface and the other end surface of the tapered light guide member 9 that enhance the directivity of the halogen emitted light as shown in FIGS.
- the member 91 since halogen light is a heat ray, the temperature becomes high, and it is better not to cover the surroundings as much as possible. If the light shielding rate is high on the halogen light source 7 side, the temperature tends to become high, so the light shielding rate is set low on the halogen light source 7 side.
- the light blocking rate of the blocking member disposed between the adjacent tapered light guide members 9 that increases the directivity of the outgoing light from the halogen light source 7 increases the directivity of the outgoing light from the xenon light source 2. It is set smaller than the light shielding rate of the light shielding members arranged between the members 4. Thereby, it is possible to prevent an increase in member temperature due to absorption of halogen light by reflection of the light shielding member. For this reason, it is better that the reflection from the light shielding member is as low as possible.

It is possible to prevent stray light L ⁇ b> 2 from entering the light guide plate 14 through the wavelength selection mirror of the light mixing unit 12 without being taken in from the side surface 9.
- the entire halogen light source 7 the tapered light guide member 9 that is a tapered coupler, and the wavelength selection mirror of the light mixing unit 12 are arranged.

Since the inner surface of the light shielding plate 93 is on the halogen light source 7 side, the reflectance is set low.
- the light shielding members 41 and 91 are a sheet or a light shielding material that has been textured on a black anodized aluminum plate having a low reflectance. These are affixed to the side (the outer peripheral wall surface side of a taper light guide member) which faces the taper light guide member of the member holding the taper light guide members 4 and 9.
- a sheet or a light shielding seal material that has been processed into an aluminum plate is covered only on the light guide member side adjacent to the gap between the light source side and the end face side of the tapered light guide members 4 and 9.
