  • Patent number: 11973308
    Abstract: The embodiments described herein provide a device and method for an integrated white colored electromagnetic radiation source using a combination of laser diode excitation sources based on gallium and nitrogen containing materials and light emitting source based on phosphor materials. A violet, blue, or other wavelength laser diode source based on gallium and nitrogen materials may be closely integrated with phosphor materials, such as yellow phosphors, to form a compact, high-brightness, and highly-efficient, white light source. The phosphor material is provided with a plurality of scattering centers scribed on an excitation surface or inside bulk of a plate to scatter electromagnetic radiation of a laser beam from the excitation source incident on the excitation surface to enhance generation and quality of an emitted light from the phosphor material for outputting a white light emission either in reflection mode or transmission mode.

  • Patent number: 11903113
    Abstract: A method includes the steps of obtaining a frame from an image sensor, the frame comprising a number of pixel values, detecting a change in a first subset of the pixel values, detecting a change in the second subset of the pixel values near the first subset of the pixel values, and determining an occupancy state based on a relationship between the change in the first subset of the pixel values and the second subset of the pixel values. The occupancy state may be determined to be occupied when the change in the first subset of the pixel values is in a first direction and the change in the second subset of the pixel values is in a second direction opposite the first direction.

  • Publication number: 20200232610
    Abstract: A laser-based fiber-coupled white light system is provided. The system includes a laser device comprising a gallium and nitrogen containing emitting region having an output facet configured to output a laser emission with a first wavelength ranging from 385 nm to 495 nm. The system further includes a phosphor member integrated with light collimation elements. The phosphor member converts the laser emission with the first wavelength to a phosphor emission with a second wavelength in either reflective or transmissive mode and mixed partially with laser emission to produce a white light emission. The system includes a transport fiber coupled to the phosphor member via the light collimation elements to receive the white light emission and deliver the white light emission remotely to one or more passive luminaries substantially free of electrical or moving parts disposed at remote distances from a dedicated source area.

  • Patent number: 10658546
    Abstract: Simplified LED chip architectures or chip builds are disclosed that can result in simpler manufacturing processes using fewer steps. The LED structure can have fewer layers than conventional LED chips with the layers arranged in different ways for efficient fabrication and operation. The LED chips can comprise an active LED structure. A dielectric reflective layer is included adjacent to one of the oppositely doped layers. A metal reflective layer is on the dielectric reflective layer, wherein the dielectric and metal reflective layers extend beyond the edge of said active region. By extending the dielectric layer, the LED chips can emit with more efficiency by reflecting more LED light to emit in the desired direction. By extending the metal reflective layer beyond the edge of the active region, the metal reflective layer can serve as a current spreading layer and barrier, in addition to reflecting LED light to emit in the desired direction.

  • Patent number: 10439107
    Abstract: This disclosure relates to light emitting devices and methods of manufacture thereof, including side and/or multi-surface light emitting devices. Embodiments according to the present disclosure include the use of a functional layer, which can comprise a stand-off distance with one or more portions of the light emitter to improve the functional layer's stability during further device processing. The functional layer can further comprise winged portions allowing for the coating of the lower side portions of the light emitter to further interact with emitted light and a reflective layer coating on the functional layer to further improve light extraction and light emission uniformity. Methods of manufacture including methods utilizing virtual wafer structures are also disclosed.

  • Patent number: 9865780
    Abstract: LED packages are disclosed that are compact and efficiently emit light, and can comprise encapsulants with planar surfaces that refract and/or reflect light within the package encapsulant. The packages can also comprise a submount with one or more LEDs, and a blanket conversion material layer on the one or more LEDs and the submount. The encapsulant can be on the submount, over the LEDs, and light reflected within the encapsulant will reach the conversion material, where it will be absorbed and emitted omnidirectionally. This allows for reflected light to now escape from the encapsulant. This allows for efficient emission and a broader emission profile, for example when compared to conventional packages with hemispheric encapsulants or lenses. In certain embodiments, the LED package provides a higher chip area to LED package area ratio.
