Patent number: 11973308Abstract: 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.Type: GrantFiled: November 24, 2020Date of Patent: April 30, 2024Assignee: KYOCERA SLD Laser, Inc.Inventors: James W.

Patent number: 10658546Abstract: 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.Type: GrantFiled: January 21, 2015Date of Patent: May 19, 2020Assignee: Cree, Inc.Inventors: Matthew Donofrio, Pritish Kar, Sten Heikman, Harshad Golakia, Rajeev Acharya, Yuvaraj Dora

Patent number: 9865780Abstract: 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.Type: GrantFiled: March 18, 2015Date of Patent: January 9, 2018Assignee: CREE, INC.Inventors: Theodore Lowes, Eric Tarsa, Sten Heikman, Bernd Keller, Jesse Reiherzer, Hormoz Benjamin
