The lighting fixture can include an LED; a primary lens disposed in an optical axis of the LED, the primary lens being configured to form a main light distribution; an auxiliary lens disposed on an outer peripheral side of the primary lens around the optical axis of the LED; and a reflecting portion configured to reflect part of light emitted from the LED to substantially an entire area of the auxiliary lens on an inner peripheral surface side thereof. The reflecting portion can be formed integrally with the primary lens and include an incident surface on which part of light emitted from the LED can be incident, a reflecting surface configured to reflect light having entered through the incident surface, and a light-exiting surface configured to allow the light reflected by the reflecting surface to exit. ## Claims ### Claim 1 A lighting fixture comprising: a light source having an optical axis; a first lens disposed on the optical axis of the light source, the first lens being configured to form a first light distribution; a second lens disposed on an outer peripheral side of the first lens around the optical axis of the light source as a center; a reflecting portion configured to reflect part of light emitted from the light source to substantially an entire area of the second lens on an inner peripheral surface side thereof; and a projection lens disposed on the optical axis and in front of the first lens and the second lens. ### Claim 2 (depends on 1) The lighting fixture according to claim 1, wherein the reflecting portion is formed integrally with the first lens and configured to include an incident surface on which part of the light emitted from the light source can be incident, a reflecting surface configured to reflect light having entered through the incident surface, and a light-exiting surface configured to allow the light having been reflected by the reflecting surface to exit. ### Claim 3 (depends on 1) The lighting fixture according to claim 1, comprising a heat sink configured to cool the light source and include a reflecting surface formed therein, the reflecting surface serving as the reflecting portion. ### Claim 4 (depends on 1) The lighting fixture according to claim 1, comprising a reflector provided separately from the first lens, the reflector serving as the reflecting portion. ### Claim 5 (depends on 1) The lighting fixture according to claim 1, wherein the light source emits light with a high intensity closer to the optical axis and the reflecting portion is configured to reflect the light with the high intensity toward the second lens on a farther side with respect to the light source. ### Claim 6 (depends on 2) The lighting fixture according to claim 2, wherein the light source emits light with a high intensity closer to the optical axis and the reflecting portion is configured to reflect the light with the high intensity toward the second lens on a farther side with respect to the light source. ### Claim 7 (depends on 3) The lighting fixture according to claim 3, wherein the light source emits light with a high intensity closer to the optical axis and the reflecting portion is configured to reflect the light with the high intensity toward the second lens on a farther side with respect to the light source. ### Claim 8 (depends on 4) The lighting fixture according to claim 4, wherein the light source emits light with a high intensity closer to the optical axis and the reflecting portion is configured to reflect the light with the high intensity toward the second lens on a farther side with respect to the light source. ### Claim 9 (depends on 1) The lighting fixture according to claim 1, wherein the second lens has an inner surface and an outer surface at least one of which is subjected to a light diffusion treatment. ### Claim 10 (depends on 2) The lighting fixture according to claim 2, wherein the second lens has an inner surface and an outer surface at least one of which is subjected to a light diffusion treatment. ### Claim 11 (depends on 3) The lighting fixture according to claim 3, wherein the second lens has an inner surface and an outer surface at least one of which is subjected to a light diffusion treatment. ### Claim 12 (depends on 4) The lighting fixture according to claim 4, wherein the second lens has an inner surface and an outer surface at least one of which is subjected to a light diffusion treatment. ### Claim 13 (depends on 5) The lighting fixture according to claim 5, wherein the second lens has an inner surface and an outer surface at least one of which is subjected to a light diffusion treatment. ### Claim 14 (depends on 7) The lighting fixture according to claim 7, wherein the second lens has an inner surface and an outer surface at least one of which is subjected to a light diffusion treatment. ### Claim 15 (depends on 1) The lighting fixture according to claim 1, wherein light emitted from the light source passes the first lens and the projection lens, which are disposed on the optical axis of the light source, to form the first light distribution as a main light distribution. ### Claim 16 (depends on 3) The lighting fixture according to claim 3, wherein light emitted from the light source passes the first lens and the projection lens, which are disposed on the optical axis of the light source, to form the first light distribution as a main light distribution. ### Claim 17 (depends on 4) The lighting fixture according to claim 4, wherein light emitted from the light source passes the first lens and the projection lens, which are disposed on the optical axis of the light source, to form the first light distribution as a main light distribution. ### Claim 18 (depends on 7) The lighting fixture according to claim 7, wherein light emitted from the light source passes the first lens and the projection lens, which are disposed on the optical axis of the light source, to form the first light distribution as a main light distribution. ### Claim 19 (depends on 8) The lighting fixture according to claim 8, wherein light emitted from the light source passes the first lens and the projection lens, which are disposed on the optical axis of the light source, to form the first light distribution as a main light distribution.
