Abstract: A device uses gated retro-reflectors to transmit uplink data in a visible light communication (VLC) system. The gated retro-reflector includes a retro-reflector and a gating shutter between the retro-reflector and a VLC light source. A light sensor receives VLC data at regular intervals in which a light pulse received during one of the intervals represents a first downloaded symbol and absence of a light pulse during another one of the intervals represents a second downloaded symbol. A controller controls the gating shutter to send uplink data from the device responsive to each received VLC light pulse. The controller opens the gating shutter during the reception of a VLC light pulse to upload a first uploaded symbol and closes the gating shutter during the reception of a VLC light pulse to upload a second uploaded symbol.

Abstract: An antimicrobial system, including a luminaire. The luminaire includes a first disinfection light source to emit a first disinfection light in a first ultraviolet (UV) band for disinfecting an occupied space of a plurality of pathogens that are exposed to the first disinfection light, the first UV band being 200 nanometers (nm) to 250 nm principal wavelength. The luminaire also includes a second disinfection light source to emit a second disinfection light in a second UV band for disinfecting an unoccupied space of the plurality of pathogens that are exposed to the second disinfection light, the second UV band being 200 nm to 400 nm principal wavelength. The antimicrobial system also includes a disinfection light control device to generate a control signal to control emission of the first disinfection light and the second disinfection light.

Abstract: A lamp includes a single string of light emitting diodes (LEDs), driven in common, configured to cause the lamp to emit a visible light output via a bulb. The lamp also includes a lighting industry standard lamp base, which has connectors arranged in a standard three-way lamp configuration, for providing electricity from a three-way lamp socket. Circuitry connected to receive electricity from the connectors of the lamp base as standard three-way control setting inputs drives the string of LEDs. The circuitry is configured to detect the standard three-way control setting inputs and to adjust the common drive to the string of LEDs to selectively produce a different visible light outputs of the lamp via the bulb responsive to the three-way control setting inputs. The lamp may also include nanophosphors pumped by emissions of the LEDs, so that the lamp produces a white light output of particularly desirable characteristics.
