  • Patent number: 10832832
    Abstract: A multi-conductor bus with radially arranged conductor wires on which addressable bead devices that may incorporate light-emitting diodes (LEDs) or other surface mount devices (SMDs) can be easily mounted. The radial bus is designed to provide an improved range of flexibility and motion while allowing for easy addition of bead devices along its length that utilize self-addressing bus protocols such as cascading device protocols. The design of the flexible, interruptible radial bus facilitates the use of pass-through and interrupted paths along the bus that simplifies the installation of addressable devices along the bus such as the bus-mounted bead devices disclosed herein.

  • Patent number: 10161614
    Abstract: A retrofit lamp (310) is provided. The retrofit lamp comprises a connector (311) for mounting the lamp at an automotive headlight; a body (312) extending from the connector along an axis (313); and a plurality of light emitting diodes (314) arranged at the body. The light emitting diodes are arranged along the axis and adapted to emit light (331, 332) laterally with respect to the axis. The retrofit lamp further comprises a reflective element (315) arranged at an end of the arrangement of light emitting diodes opposite to the connector. The reflective element is adapted to reflect some light (332) emitted by the light emitting diodes. Additionally—the extension of the arrangement of light emitting diodes along the axis is shorter than a light emitting area (114) of a reference replaceable headlight bulb (110), and—the reflective element (315) is configured to establish a virtual prolongation (340) of the arrangement of LEDs.

  • Patent number: 10145526
    Abstract: A headlamp module comprises a connecting base, a substrate, and at least two edge-type light emitting diode (LED) units. The at least two edge-type LED units are mounted to opposite surfaces of the substrate facing away from each other. Each edge-type LED unit comprises an LED chip, a wavelength converting layer, and a light reflecting layer. The LED chip comprises a bottom surface, a light emitting surface facing away from the bottom surface, and first sidewalls. The wavelength converting layer covers the light emitting surface and the first sidewalls. The wavelength converting layer converts emitted light to a desired range of wavelengths. The light reflecting layer reflects the converted light toward the second sidewalls, thus expanding the angle and brightness of light around the headlamp module and avoiding an unlit or dark area immediately around the headlamp module.

  • Patent number: 10082283
    Abstract: A method for a light bulb or fixture to emit light and measure ambient light. The method includes driving solid state light sources, such as LEDs, in the bulb with a cyclical signal to repeatedly turn them off and on, where the light sources are turned off and on at a rate sufficient for the bulb to appear on. The method also includes measuring ambient light via a light sensor in or on the bulb during at least some times when the light sources are off, and outputting a signal related to the measured ambient light. In some cases the light sensor saturates when the solid state light sources are active and measures the ambient light level when the solid state light sources are not active. The ambient light level signal can be used to control when the light bulb is on and an intensity of light output by the bulb.
