    摘要: Methods of controlling a backlight unit including a plurality of solid state light emitting devices include receiving a request to set a color point of the backlight unit at a requested color point, and determining if the requested color point is within an acceptable range. In response to the requested color point being outside the acceptable range, a modified color point is selected in response to the requested color point, and a color point of the backlight unit is set at the modified color point. Corresponding solid state lighting units are also disclosed.

    摘要: An image sensing system for a vehicle includes an imaging sensor having an array of light sensing photosensor elements. The imaging sensor views through the windshield of the equipped vehicle at a region of the windshield that is swept by a windshield wiper of the equipped vehicle. The imaging sensor is operable to capture image data and is operable to capture frames of image data at a plurality of exposure periods. The image sensing system identifies objects in the forward field of view of the imaging sensor via processing of the captured image data by an image processor. The objects identified by the image sensing system may include at least one of (i) headlights of approaching vehicles, (ii) taillights of leading vehicles, (iii) lane markers on a road being traveled by the equipped vehicle, (iv) traffic signs, (v) traffic lights, (vi) stop signs and/or (vii) caution signs.

    摘要: A lighting panel system includes a lighting panel having a string of solid state lighting devices and a current supply circuit having a voltage input terminal, a control input terminal, and first and second output terminals coupled to the string of solid state lighting devices. The current supply circuit is configured to supply an on-state drive current to the string of solid state lighting devices in response to a control signal. The current supply circuit includes a charging inductor coupled to the voltage input terminal and an output capacitor coupled to the first output terminal. The current supply circuit is configured to operate in continuous conduction mode in which current continuously flows through the charging inductor while the on-state drive current is supplied to the string of solid state light emitting devices.
