  • Publication number: 20230175671
    Abstract: A light-emitting diode (LED) can have a light-emitting surface that can emit emitted light. A filter, disposed on the light-emitting surface, can be at least partially transmissive in a first area and at least partially reflective in a second area. The first area can direct at least some of the emitted light through the filter to form shaped light that extends over an area corresponding to a shape of a static light pattern. The second area can reflect at least some of the emitted light into the LED through the light-emitting surface. A lens can bring the shaped light to a focus that has the shape of the static light pattern. To increase a contrast of the focus, an absorber, disposed on the second area of the filter, can absorb emitted light that is transmitted through the second area of the filter.

  • Patent number: 11233180
    Abstract: A light emitting diode (LED) device may include an LED die having a first surface on a substrate. A first phosphor layer may be formed on a second surface and sides of the LED die. The second surface may be opposite the first surface. A second phosphor layer may be formed on the first phosphor layer. The second phosphor layer may have a peak emission wavelength (Lpk2) located between a peak emission wavelength of the LED die (LpkD) and a peak emission wavelength of the first phosphor layer (Lpk2).
