  • Patent number: 10206266
    Abstract: An automated dimming load controller automatically measures the relationship between the current draw and the dimmer setting for each light or group of lights connected to the load controller. Once measured, the relationship between the current draw and the dimmer setting can be used to enable the dimmer controller to adjust the lights between their minimum and maximum effective illumination. This automatic setting of the dimmer controller may be performed regularly to accommodate changes in performance or replacement of any of the connected lights, drivers or ballasts.

  • Patent number: 9482413
    Abstract: Lighting device (1) comprising a plurality of LEDs (2a-2h) and a movable member (3) comprising a plurality of translucent segments (S1-S8) arranged such that the light from the LEDs (2a-2h) is transmitted therethrough. At least one of the translucent segments (S1-S8) comprises a wavelength conversion material. The lighting device (1) further comprises a control unit (5) for adjusting the color of the light emitted from the lighting device by controlling the power supplied to each one of the LEDs (2a-2h) in correspondence to the movable member (3), and by controlling the total power supplied to the lighting device (1) independently from the power supplied to each one of the plurality of LEDs (2a-2h).

  • Patent number: 9467667
    Abstract: A white balance adjustment method and apparatus for a single DLP projector system is disclosed. The projection system includes a solid state light source device, a sync signal generator, and a controller. The light source device generates an output which is a repeating color sequence of at least two primary color lights. The sync signal generator generates a synchronization signal representing a timing of the color sequence of the output light. The controller calculates drive current values corresponding to each of the two primary colors based on a target white balance and measured color properties of the output light, and supplies a modulated drive current to the light source device. The modulated drive current is synchronized to the sync signal and has the calculated drive current values. As a result, a white light having the target white balance is output.

  • Patent number: 9377673
    Abstract: An electronic display device provides closed-loop verification that specific content has been displayed by the display device. When desired digital image content is rendered as an image or video by the electronic display device, a confirmation signal is generated by one or more components of the display device to verify that the image content has been successfully displayed. The confirmation signal may include performance measurements of the one or more components of the display device and/or a signature output that is associated with a signature code embedded in the image content. The signature output uniquely identifies the digital image content.

  • Patent number: 9365156
    Abstract: A lighting apparatus, in particular a reading lamp, is provided. The apparatus can be recessed in a trim of a passenger cab of a vehicle, which can be a land vehicle, an aircraft, or a watercraft. The apparatus has a first light-emitting device that is pivotably mounted to a recess-mounting frame, so that a light-emitting direction of the first light-emitting device with respect to the recess-mounting frame is changeable. To simplify the design of the apparatus, a second light-emitting device is mounted to a visible side of the recess-mounting frame. The second light-emitting device at least partially surrounds the first light-emitting device and is fitted to the recess-mounting frame, so that the light-emitting direction of the second light-emitting device is invariable.

  • Patent number: 9297516
    Abstract: A phosphor wheel for converting pump light to conversion light, on which a first phosphor for emitting conversion light of a first color and a second phosphor for emitting conversion light of a second color are provided. The light of first and second phosphors, which are arranged in a manner spatially separated from one another on the phosphor wheel, has the same hue in this case. Depending on the requirement, either the first or the second phosphor can thus be selected.
