    摘要： A method for operating an automotive lighting device including at least one solid-state light source. The method includes defining a color allowance condition, feeding the light source with a current value which produces a luminous flux value higher than a minimum luminous flux threshold value, measuring the temperature in the light source, checking whether the output color satisfies the allowance condition and increasing or decreasing the current value, always keeping the current such as it produces an acceptable color. With the checking includes perform a pulse width modulation of the current value to keep an average value of the current which produces a luminous flux value higher than the minimum luminous flux threshold value. The invention also provides an automotive lighting device comprising a control element to carry out the steps of this method.

    摘要： Vehicle headlights are equipped with a right-side lamp, a left-side lamp, and a control unit. A right-side light distribution pattern and a left-side light distribution pattern include an overlapping area and a non-overlapping area. In a case where the steering angle is greater than the prescribed angle, the control unit controls power supplied to light-emitting parts of the right-side lamp and power supplied to light-emitting parts of the left-side lamp such that: a first area of a first light distribution pattern is located in the non-overlapping area; a second area of a second light distribution pattern is located in the overlapping area; and a first intensity of the light in the first area becomes greater than the sum of a second intensity of the light in the second area and a third intensity of the light in the area overlapping the second area within the first light distribution pattern.

    摘要： A system may have lights produce illumination. A light may be provided with a collimated light source that produces collimated light. The collimated light source may use lenses or reflective optical elements to produce the collimated light. The light may have an array of light elements each of which emits a respective beam of the illumination. Each light element may have a preshaping lens that receives the collimated light and produces corresponding preshaped output light and an output lens that receives the output light from the preshaping lens and produces a corresponding beam of the illumination. An electrically adjustable shutter may be located between each preshaping lens and output lens to adjust the illumination between a low-beam pattern and high-beam pattern.

    摘要： The invention relates to a lighting system including a pixelated light source provided with a plurality of selectively activatable emissive elements, each having a rectangular shape with a height dimension and a width dimension, the width dimension being the same for all the emissive elements, and an optical device having an optical axis and configured to project an image of each of the emissive elements. The optical device configured such that the images have a width dimension that increases non-linearly moving away from the optical axis.
