Abstract: The radar apparatus includes a light emission instructing unit and a determination unit. The light emission instructing unit is configured to instruct the emission unit to emit light into the search region. Further, the light emission instructing unit is configured to reduce at least one of the number of times of emission, the emission frequency, and the emission intensity for a predetermined designated region, when the own vehicle is performing the designated movement compared to when the own vehicle is not performing the designated movement.

Abstract: A light-source apparatus includes a light-source chip, a case, first and second electrically-conductive parts, a substrate, an electromagnetic shield plate, an electrically-conductive layer and an electrically-conductive unit. The light-source chip is received in the case. Each of the first and second electrically-conductive parts is a part of the case. The case is mounted to the substrate. The electromagnetic shield plate covers at least part of the substrate. The electrically-conductive layer is formed on the substrate and electrically connected with both the second electrically-conductive part and the electromagnetic shield plate. The electrically-conductive unit is provided to electrically connect the first electrically-conductive part and the electromagnetic shield plate.

Abstract: A light-source apparatus includes a light-source chip, a case, a substrate, an electromagnetic shield plate and a thermally-conductive member. The light-source chip is received in the case. The case is mounted to the substrate. The electromagnetic shield plate covers at least part of the substrate. The thermally-conductive member is arranged to abut both the case and the electromagnetic shield plate.

Abstract: A distance measurement apparatus includes a light emission circuit that includes a switch, a capacitor, a light-emitting element, and a protection element. The light emission circuit charges and discharges the capacitor by opening and closing the switch based on a light emission control signal, and enables the light-emitting element to emit light using electric power during discharge by the capacitor. The light emission circuit is configured such that a parasitic inductance of a first circuit is greater than a parasitic inductance of a second circuit, where the first circuit is a circuit in which the switch, the capacitor, and the light-emitting element are connected in series and in a ring shape, and the second circuit is a circuit in which the switch, the capacitor, and the protection element are connected in series and in a ring shape.
