Sudhir Subramanya has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12276827
    Abstract: A light source useful for architectural lighting, general lighting, street lighting, or other lighting applications includes a plurality of light emitting diodes. A least some light emitting diodes can be sized between 30 microns and 500 microns. A plurality of micro-optics sized less than 1 millimeter are positioned over at least some of the plurality of light emitting diodes. A controller may be connected to selectively power groups of the plurality of light emitting diodes to provide different light beam patterns.

  • Publication number: 20220313851
    Abstract: A decontamination apparatus for disinfecting a surface can include a flexible textile, an array of LEDs, and a flexible cover layer. The flexible textile can have a first side facing a first direction and a second side facing a second direction opposite the first direction. The array of LEDs can be configured to output radiation in at least two separate wavelength ranges corresponding to an ultraviolet radiation range and an infrared radiation range. The flexible cover layer can cover the array of LEDs and be transparent to at least the ultraviolet radiation range. The flexible cover layer can comprise a plurality of projections configured to maintain a consistent distance between the array of LEDs and a surface to be disinfected. The flexible textile, the array of LEDs, and the flexible cover layer can be coupled together to form a flexible blanket that conforms to a contour of the surface.

  • Patent number: 11314012
    Abstract: A light source useful for architectural lighting, general lighting, street lighting, or other lighting applications includes a plurality of light emitting diodes, with at least some light emitting diodes sized between 50 microns and 500 microns. A plurality of micro-optics sized less than 1 millimeter are positioned over at least some of the plurality of light emitting diodes. Each combination of light emitting diode and associated micro-optic is positioned within a Rayleigh distance to each other, sufficient to both present a substantially uniform visual appearance and provide a substantially uniform light beam. In some embodiments the height of the light emitting diodes, their supporting substrate and electrical traces, and associated optics is less than 5 millimeters.
