AUTOMOTIVE LAMP

A scanning light source includes a light source, and scans the output light of the light source ahead of a lamp. A control apparatus controls the lighting on/off state of the semiconductor light source in synchronization with the scanning operation of the scanning light source. The control apparatus judges the presence or absence of an abnormal state with at least one from among (i) a timing immediately before switching from a lighting-on state to a lighting-off state and (ii) a timing immediately before switching from a lighting-off state to a lighting-on state as a judgment timing.

Methods and apparatus for illumination with laser modulated adaptive beam shaping
10753566 · 2020-08-25 · ·

An illumination system includes at least first and second laser illumination sources. A down converter material emits light when illuminated by one or more of the laser illumination sources. The first laser illumination source is arranged to illuminate only a first portion of the down converter material. The second laser illumination source is arranged to illuminate only a second portion of the down converter material. Control circuitry causes the first laser illumination source to adaptively vary a first intensity of illuminating the first portion of the down converter material, causes the second laser illumination source to adaptively vary a second intensity of illuminating the second portion of the down converter material, and causes the light modulator to allow a selected amount of the down converter material's emitted light to be projected from the system.

The lighting device for a vehicle has two light sources and a wavelength conversion device excited by the combination of the radiations from the two light sources. A first light source is associated with a scanning system projecting, by scanning, a first light radiation onto a first conversion region of the device, while a second light source with semiconductors emits a second light radiation into a second conversion region of the device. The second source, different from the first source and whose luminance level is typically less high, is provided with light-emitting units of submillimetric dimensions. The beams produced by the device respectively in the first region and in the second region have different characteristics and complement one another to produce one or more lighting functions.
