A light distribution control device, if a first upper limit number N≥the number of near-distance targets T, controls a lamp to irradiate the near-distance targets with light having illuminance according to attributes of the near-distance targets; if a remaining number M≥the number of long-distance targets T, controls the lamp to irradiate the long-distance targets with light having illuminance according to attributes of the long-distance targets; if N<T, controls the lamp to form a light distribution pattern that does not depend on the near-distance targets and the long-distance targets; and, if M<T, controls the lamp to form a light distribution pattern that does not depend on the long-distance targets.

Light distribution control device, vehicle light system, and light distribution control method

A high-definition lamp unit emits lamp beam with a light distribution containing a cut-off line. A sensor is provided to detect a dynamic component of a pitch angle of a vehicle body during travel. A controller shifts the level of a cut-off line of the light distribution up and down, with reference to a predetermined level defined as a base, corresponding to the dynamic component of the pitch angle of the vehicle body.

Lamp system

A vehicular headlight () includes a first light source unit (), a second light source unit (), a temperature sensor (), and a control unit (). When the temperature derating is performed on the first light source unit () based on the temperature in a state where the light distribution pattern () of a low-beam is formed, the control unit () controls the power to be supplied to each of a plurality of light-emitting elements () so that the light amount of at least a part of the first light with which at least a region () of a first light distribution pattern () is irradiated decreases as compared with that before the temperature derating.

Vehicular headlight

A vehicle headlight () includes a first lamp unit () that includes a light distribution pattern forming unit () which forms a predetermined light distribution pattern (P) according to the light amount of the light emitted from a plurality of light emitting elements (), and a second lamp unit (), in which a light distribution pattern (PL) of a low beam is formed by light emitted from the first lamp unit () and light emitted from the second lamp unit (), and in the light distribution pattern (PL) of the low beam, the elbow point (EP) is included in a predetermined region (CA) formed by light including the light from the first lamp unit (), and a first side region (SA) and a second side region (SA) sandwiching the predetermined region (CA) are formed by the light emitted from the second lamp unit ().

Vehicle headlight

An on-vehicle electronic circuit mounting board includes: a surface mount type package component including a plurality of electrode pads disposed along an outer periphery of a component bottom surface; and a printed wiring board having a plurality of lands disposed along the plurality of electrode pads on a top surface of the printed wiring board opposed to the component bottom surface, and in which each land is disposed to be opposed to the corresponding electrode pad and electrically connected to the electrode pad by soldered connection. An outer soldering slope and an inner soldering slope are formed between a land of the plurality of lands and an electrode pad corresponding to the land, and the land is shifted with respect to the corresponding electrode pad such that one of the outer soldering slope and the inner soldering slope faces the wiring board side and the other faces the component side.

On-vehicle electronic circuit mounting board

A vehicular rear panel with a new configuration is provided. The vehicular rear panel according to an aspect of the present disclosure is made of a resin material and disposed on a rear vehicle body part. The vehicular rear panel includes a light guiding unit configured to guide light from the light source along an extending direction of the vehicular rear panel and a light emitting unit configured to emit light in the light guiding unit to a rear side of a vehicle.
