  • Patent number: 10578789
    Abstract: An optical system and method provides at least one, and preferably an array of relatively small, high brightness light sources with a surrounding surface that exhibits brightness, thereby reducing the contrast between the high brightness produced by the light sources and the brightness of their surrounding surfaces. The optical system includes a light waveguide structure that captures a portion of the light from the individual high-brightness light sources, and then re-emits the source light to create brightness in the light sources' surrounding surfaces. The optical system is particularly adapted for use with LEDs, but could be used with LEDs, but could be used with other high brightness light sources.

  • Patent number: 10571095
    Abstract: Optics for asymmetrically redirecting light from one or more light engines include a dome optic, and first and second reflecting surfaces. The dome optic refracts light emitted by the light engines. The first reflecting surface redirects at least a portion of the light that is initially emitted toward a backward horizontal direction, toward the forward horizontal direction. The first reflecting surface extends substantially vertically and along a transverse horizontal direction, proximate to and behind the dome optic, and has a height greater than or equal to a height of the dome optic. The second reflecting surface reflects downwardly at least a portion of the refracted light that is initially emitted in the forward horizontal direction. The second reflecting surface is proximate to the dome optic and forward of the dome optic, and forms an angle of 45 degrees or more with respect to vertical.

  • Patent number: 10544912
    Abstract: A loadable cassette holds a planar light source, such as a flat OLED panel, along with a companion driver board in a manner that allows both the light source and driver board to be operatively and replaceably connected to a luminaire or lighting system. The cassette maintains an air gap between the light source and driver board so as to prevent heat produced by the driver board from damaging the light source.

  • Patent number: 10539278
    Abstract: A luminaire is provided for illuminating a task surface and a volume of space above and about the task surface, including a limited human occupiable space proximate the task surface. The luminaire includes a body having a base end and an extension portion extending from the base end. A task lighting element on the body, and suitably at the base of the body, directs light in a directional light distribution pattern toward a task surface. Area light sources on the extension portion of the body emit light in a diffuse light distribution pattern for illuminating the volume of space over the task surface and a limited human occupiable space proximate the task surface.

  • Patent number: 10527272
    Abstract: An adapter for mounting a luminaire to a track of a track lighting system includes a main body and a head having axes that are angled with respect to each other. The head is configured to be insertable into the track and rotatable to align the adapter body with the track ant to make electrical contact with conductors within the track. The rotation required is less than 70 degrees, and may be as little as 13 degrees or less, enabling installation of track lighting near obstructions.

  • Patent number: 10524330
    Abstract: A system adjusts detection parameters used to process a signal from a PIR sensor to reduce false triggers. A detection module receives a sensor output signal from a PIR sensor and inputs from environmental sensors, including a temperature sensor. The detection module adjusts detection parameters of a bandpass filter and/or a thresholod comparison module based on the inputs from the environmental sensors. The detection module generates a motion presence signal that indicates whether motion has been detected and that compensates for external environmental factors.

  • Patent number: 10512128
    Abstract: A master lighting fixture and a satellite lighting fixture can each include an LED board including multiple LEDs that can emit visible light. A power supply and a LED regulator can be connected to the LED board in the master lighting fixture to provide power to operate the LED board. The LED board in the master lighting fixture can be connected to the LED board in the satellite lighting fixture to form a circuit to allow the power provided by the LED driver to be transmitted to the LED board in the satellite lighting fixture. A defect in the LED board in the master lighting fixture or the satellite lighting fixture can open the circuit, which can prevent power from being transmitted through the LED boards to enhance the performance of LEDs in the LED boards or reduce a risk of damage that can be caused by the LED boards.

  • Patent number: 10455655
    Abstract: Battery charge function may be in an LED driver which eliminates the duplication of line interface circuitry. A single line interface circuit provides the input power conversion for both the battery charge function and normal operation of the LED driver. During a loss of power, the LEDs may be controlled using power from the battery backup module.

  • Patent number: 10455493
    Abstract: An intelligent streetlight may include a modem capable of communicating on a mobile communications network. The intelligent streetlight may be communicate with a network operations center (“NOC”) via the mobile communications network. In some aspects, the intelligent streetlight configures the modem to transmit on the mobile network based on multiple types of network provisioning data. For example, the modem may have a network configuration, such as a low-bandwidth mobile data plan, based on stored provisioning data. The modem may reconfigure the modem based on additional provisioning data for an additional network configuration, such as a high-bandwidth mobile data plan. In some cases, the additional provisioning data is requested by the streetlight from the NOC. In some cases, the NOC may provide the additional provisioning data to multiple intelligent streetlights, such that the multiple streetlights are each reconfigured in a short period of time.

  • Patent number: 10448471
    Abstract: Certain aspects involve lighting systems in which a dimming curve of the illumination can be selectively modified. For instance, a lighting system includes a light source configured for emitting light at a target color temperature and a switch configured to receive a selection of a dimming curve from a predefined set of dimming curves. When in a first position, the switch configures the light source to adjust a lumen intensity of the light source according to a dimming adjustment signal and a first dimming curve. When in a second position, the switch configures the light source to adjust the lumen intensity according to a dimming adjustment signal and a second dimming curve that is different from the first dimming curve.
