Vehicular lamp
A vehicular lamp 1 including a lamp chamber 7 , which is formed with a lamp body 3 and a transparent front cover 5 attached to the front opening of the lamp body, and a lamp unit 13 , which includes a reflector 9 and a light source 11 and is provided in the lamp chamber 7 so that the optical axis direction of the lamp unit is adjusted by a tilting movement adjustment mechanism 15 , wherein a millimeter wave radar device 25 is attached to the lamp body, and a reflection mirror 31 that reflects, toward the front of the lamp, a millimeter wave signal 29 emitted by the millimeter wave radar device is attached to a supporting frame 21 which is a part of the tilting movement adjustment mechanism.
1. A vehicular lamp comprising
a lamp chamber formed by a lamp body having a front opening and a transparent front cover attached to the front opening of the lamp body, and
a lamp unit formed by a reflector and a light source and provided in the lamp chamber so that an optical axis direction thereof is adjustable use of by a tilting movement adjustment mechanism, wherein
a millimeter wave radar device, which emits a millimeter wave to detect a separation distance and a relative velocity with respect to an object based on a reflection wave from an object that has reflected the emitted millimeter wave, is attached to the lamp body and provided in the lamp chamber, and
a reflection minor, which reflects, toward front of the vehicular lamp, the millimeter wave emitted by the millimeter wave radar device, is provided within the lamp chamber in such a manner that a direction in which the millimeter wave is reflected is adjustable with use of the tilting movement adjustment mechanism.
2. The vehicular lamp according to claim 1 , wherein the reflection mirror is attached to the tilting movement adjustment mechanism.
3. The vehicular lamp according to claim 1 , wherein the millimeter wave radar device is positioned beneath the lamp unit.
4. The vehicular lamp according to claim 1 , wherein
the lamp unit is a projector type lamp unit in which a reflection beam from the reflector is radiated toward front of the vehicular lamp via a projection lens provided in front of the reflector, and
the millimeter wave radar device is provided on a side of the projector type lamp unit.
5. The vehicular lamp according to claim 1 , wherein the millimeter wave radar device is attached to the lamp body in such a manner that at least a part of the millimeter wave radar device is exposed to outside of the lamp body.
