  • Patent number: 10405383
    Abstract: A lighting control circuit is for controlling a lighting arrangement comprising a set of at least two light sources in parallel. A current driver is used to deliver a drive current to the lighting arrangement. A switch is associated with the second light source, which may for example be provided for color adjustment, and the duty cycle of the switch is controlled as well as the overall drive current setting thereby to control the color or color temperature setting and dimming level of the lighting arrangement. The controller derives the required average output current and the expected average output voltage from the current driver based on the determined duty cycle and the dimming level, and then derives the current driver setting. In this way, the current driver is accurately controlled to deliver the required output. This enables a single stage driver to be used to control the color or color temperature of multiple light source channels, for example in dependence on a dimming level.

  • Patent number: 9903578
    Abstract: An air cooled horticulture lamp fixture for growing plants in confined indoor spaces. The fixture seals the lamp and heat generated by the same to a reflector interior. Flow disruptors create turbulence in a cooling chamber thereby enhancing thermal transfer into a cooling air stream that flows over and around the reflector's exterior side thereby convectively cooling the lamp using the reflector as a heat sink. The lamp is effectively maintained at operational temperatures and the fixture housing is insulated from the hotter reflector by a gap of moving cooling air, allowing improved efficiencies of the lamp bulb in confined indoor growing spaces.

  • Patent number: 9885775
    Abstract: A luminaire is provided for use in determining an orientation of a camera based on an image of the luminaire captured by the camera. The luminaire comprises a light source having an on state in which it emits light and an off state in which it does not emit light, and being of a shape having a symmetry in the off state. The luminaire also comprises a controller configured to control the light source to emit said light in the on state with a lighting effect that breaks said symmetry. A device comprising receives an image of the light source from a camera, and determines an orientation of the camera relative to the light source by performing a geometric perspective calculation based on the image of the light source. An ambiguity in the orientation is resolved by detecting the asymmetry in the light emitted by the light source.

  • Patent number: 9739437
    Abstract: A vehicular lamp unit has a substrate, a light source having a first light-emitting element and a second light-emitting element disposed on the substrate, and an optical element having the light source attached thereto. The substrate is long in a first direction. The optical element radiates emitted light of the first and second light-emitting elements toward a front of the vehicular lamp unit, with a desired light distribution. A reference portion serving as a positioning reference for the optical element is provided in a part of the substrate. The first and second light-emitting elements are arranged in the first direction. The first light-emitting element illuminates an area having high light intensity of the light distribution. The second light-emitting element illuminates an area having low light intensity of the light distribution. The first light-emitting element is mounted at a position closer to the reference portion in the first direction than the second light-emitting element.
