Abstract: A light apparatus mounted on a vehicle includes a lamp unit having: a first cover, and a light source that emits light through a first cover into a predetermined area including a first direction. The light apparatus also includes: a radar unit provided on a lower side or an upper side of the lamp unit, and a separator provided between the lamp unit and the radar unit. The radar unit includes: a circuit board having a board surface arranged in a substantially horizontal state, and an antenna unit that transmits an electromagnetic wave in a range including a second direction different from the first direction and that receives a reflected wave from an object existing outside the vehicle. The antenna unit is arranged in the board surface.

Abstract: A light apparatus mounted on a vehicle includes a lamp that emits light into a first region through a first cover and a radar provided on a lower side or an upper side of the lamp. The radar includes a separator provided between the lamp and the radar, a circuit board having a board surface arranged in a substantially horizontal manner, and an antenna that is disposed on the board surface of the circuit board, transmits electromagnetic waves through a second cover in a second region that is at least partially different from the first region, and receives reflected waves through the second cover from objects outside the vehicle in the second region.

Abstract: An in-vehicle light apparatus for a vehicle is provided and includes lamp radar units. The lamp unit includes a light source and a reflector arranged around the light source and outputting light from an opening area of the reflector to a predetermined region including in a first direction. The radar unit is provided on a lower or upper side of the lamp unit and includes a circuit board having a board surface arranged in a substantially horizontal state and an antenna unit that transmits an electromagnetic wave and receives a reflected wave in a second direction. The opening area extends in a third direction different from the first direction and the second direction in plan view, and a direction perpendicular to the second direction on the board surface is a direction intersecting the first direction and non-parallel to the third direction.
