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: 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.

Abstract: A radar device includes radar transmission and receiving circuits. The radar transmission circuit transmits one or more transmission signals, each having a transmission period Tr. The radar receiving circuit receives one or more reflected signals in which the transmission signals are reflected by an object and estimates a direction of the object based on the reflected signals. The radar transmission circuit includes Nt transmission antennas. A control circuit sets a transmission gap period between a first and second periods, with the transmission gap period being a period during which the transmission signals are not transmitted. The first period is equal to an integral multiple of a period Np, the period Np is equal to or more than Nt times the transmission period Tr, and the second period is set after the first period and is equal to an integral multiple of the period Np.

Abstract: A radar apparatus includes a circuit board including a board surface provided with an antenna module for transmitting an electromagnetic wave, a housing accommodating the circuit board and including a facing wall facing the board surface, and a heat transfer module transferring heat generated inside the housing to the housing. The facing wall includes a transmission portion transmitting therethrough the electromagnetic wave transmitted from the antenna module and an absorption portion having a thickness different from the thickness of the transmission portion and absorbing the electromagnetic wave which is incident. The heat transfer module includes a first transfer member placed to be in contact with the absorption portion in the housing and a second transfer member transferring the heat to the first transfer member.
