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.

In-vehicle light apparatus

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.

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.

An in-vehicle light apparatus for monitoring a region in a first direction outside a vehicle, including: a lamp unit including a light source and a reflector; a radar unit including a circuit board disposed such that a board surface extends substantially along the horizontal direction on a lower side or an upper side of the lamp unit and a plurality of antenna elements disposed in the hoard surface of the circuit hoard to transmit an electromagnetic wave in the first direction; and the plurality of the antenna elements are arranged in an array on the first direction side relative to the reflector in plan view, and an array direction of the plurality of antenna elements is a direction intersecting the first direction and non-parallel to an extending direction of an end portion on the side of the first direction of the reflector in plan view.
