    摘要： A lighting unit with a projection lens, a light source, a reflector, a shade, and a convex lens. The projection lens is arranged on an optical axis extending in a longitudinal direction of a vehicle. The light source is arranged on a rear side of a rear side focal point of the projection lens. The reflector reflects forward light from the light source toward the optical axis. An upper end edge of the shade passes through a vicinity of the rear side focal point. The shade shields part of a reflected light from the reflector. The convex lens is arranged between the light source and the shade, and converges light from the light source into the vicinity of the upper end edge of the shade.

    摘要： A lighting control apparatus of a vehicle-purpose lighting device can contribute power saving effect, and prevention of a deterioration of a semiconductor light source, and also, can maintain driving safety characteristics. When an input terminal becomes a low level while a vehicle is stopped, a PNP transistor is turned ON, so that a source current I1 flows through a current detecting terminal; a switching regulator lights an LED under beam attenuating operation of 70% in accordance with a light emitting degree capable of satisfying a luminous intensity distribution defined in a law; when an upper beam is lighted, the input terminal becomes a low level; a PNP transistor is turned ON; a source current I2 flows through the current detecting terminal, so that the light emitting degree of the LED is further decreased, and thus, the switching regulator lights the LED under beam attenuating operation of 50%.

    摘要： A vehicle lamp includes a plurality of semiconductor light emitting devices, and a reflector for reflecting light emitted from the semiconductor light emitting devices toward a front side of the vehicle lamp. The reflector is partitioned into a plurality of light emitting areas that are radially formed around an optical axis extending in a front-rear direction of a vehicle. Each of the semiconductor light emitting devices is disposed on an outer peripheral portion of one of the light emitting areas respectively. Each of the reflecting surfaces of the reflector is provided in one of the light emitting areas respectively.

    摘要： Lamp piece units in a parabolic pillar type capable of forming a luminous intensity distribution pattern prolonged sideways are formed as side irradiating lamp piece units. Thereby, a portion of diffused and reflected light from reflectors of the respective side irradiating lamp piece units is prevented from being blocked by other lamp piece constituting members, even when a surface shape of a vehicular headlamp is flexed to the rear side. Further, although the respective side irradiating lamp piece units are constituted by the lamp piece units of the parabolic pillar type having an angular outer shape as a whole, a large depth space for arranging the units is dispensed with.
