Abstract: The invention provides a method for operating an automotive lighting device (1) comprising at least two solid-state light modules (2). This method comprising the steps of defining a homogeneity criterion for each pair of colours, feeding the first light module with a first current value which produces a first output colour in the first light module and feeding the second light module with a second current value which produces a second output colour in the second light module, wherein the pair first output colour-second output colour fulfils the homogeneity criterion. The invention also provides an automotive lighting device (1) comprising a control element (3) to carry out the steps of this method.

Abstract: An automotive lighting device and 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 a luminous flux value higher than the minimum luminous flux threshold value and producing a color which satisfies the allowance condition.

Abstract: 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.
