发明名称 Vehicle light
摘要 A vehicle light is capable of preventing gaps (areas darker than peripheral areas) from being formed in between a plurality of illumination areas that are independently controlled to be illuminated with light or not to be illuminated with light, or suppressing the generation of such gaps. The vehicle light can include a projection lens and a light source unit disposed behind the rear-side focal plane of the projection lens. The light source unit can include a plurality of tubular portions each having a reflective inner peripheral surface, and a plurality of semiconductor light emitting elements. Exit openings of the plurality of tubular portions can be arranged side by side in a substantial horizontal direction behind the rear-side focal plane of the projection lens. Adjacent ones of the plurality of exit openings of the tubular portions can be defined and partitioned by a common vertical edge.

主权项 1. A vehicle light having an optical axis extending in a front-to-rear direction of a vehicle body, the vehicle light comprising: a projection lens disposed substantially at the optical axis and having a rear-side focal plane; and a light source unit disposed behind the rear-side focal plane of the projection lens, wherein, the light source unit includes a plurality of tubular portions each having a reflective inner peripheral surface, an incoming opening at one end, and an exit opening at an opposing end, anda plurality of semiconductor light emitting elements each configured to emit light during operation that enters a corresponding one of the tubular portions through the incoming opening, is reflected by the reflective inner peripheral surface, and exits through the exit opening, the exit openings of the plurality of tubular portions are arranged side by side in a substantially horizontal direction behind the rear-side focal plane of the projection lens, adjacent ones of the plurality of exit openings of the tubular portions are defined by a common vertical edge while partitioned by the common vertical edge, and the plurality of tubular portions each are configured as a tapered cone shape such that the exit opening is wider than the incoming opening.
