  • Patent number: 10156716
    Abstract: A phosphor wheel includes: a substrate; and a plurality of phosphor layers disposed apart from each other on the substrate along a circumferential direction. Each phosphor layer includes a first fluorescence emitter and a second fluorescence emitter that are disposed side by side along the circumferential direction and emit fluorescence having mutually different colors. A fluorescence efficiency of the second fluorescence emitter when the second fluorescence emitter is irradiated with excitation light is lower than a fluorescence efficiency of the first fluorescence emitter when the first fluorescence emitter is irradiated with the excitation light. In plan view, a blank portion is located adjacent to the second fluorescence emitter in the circumferential direction, the blank portion being a portion of the substrate where no phosphor layer is disposed. The phosphor wheel rotates to cause the second fluorescence emitter to be irradiated with the excitation light immediately after the blank portion.

  • Patent number: 10131266
    Abstract: A vehicle lamp (10) with a progressive direction indicator function comprises a direction indicator zone divided into a series of illuminable portions. The direction indicator zone is generally C-shaped, comprising a head 68) and a pair of tails (64, 66), joined by the head (68), that extend in an inboard direction from the head. The tails (64, 66) extend beside each other in the inboard direction and are spaced apart along their length. The head (68) extends between the tails (64, 66) in a direction transverse to the inboard direction, the height of the head (68) in that transverse direction being greater than combined thicknesses of the tails (64, 66) in that transverse direction. To draw an observer's eye in an outboard direction, the illuminable portions are controllable in use to illuminate the direction indicator zone progressively in an outboard direction along the tails (64, 66) to the head (68), and then to illuminate the head convergently in a direction transverse to the outboard direction.
