    Abstract: A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED while the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilize the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.

    Abstract: A method of manufacturing a semiconductor device with precision patterning is disclosed. A structure of a small dimension is created in a material, such as a semiconductor material, using a first and a second pattern, the patterns being identical but displaced over a distance with respect to each other. Two mask layers are used, wherein the first pattern is etched into the upper mask layer with a selective etch, and the second pattern is created on the upper mask layer or on the lower mask layer at locations where the upper mask layer has been removed. A part of the lower mask layer and/or the upper mask layer is etched according to the second pattern, resulting in a mask formed by remaining parts of the lower and upper mask layers, the mask having a structure with a dimension determined by a displacement of the second pattern with respect to the first pattern.

    Abstract: A lighting system for exterior lights of an automobile comprises a first lighting unit (10,12,14,16) primarily for outputting a first automotive light signal and a failure detection system (26) for detecting a failure of the first lighting unit (10,12,14,16). A second lighting unit is primarily for outputting a second automotive light signal. The second lighting unit comprises an LED light unit. A controller (30) is adapted to determine if there is failure of the first lighting unit, and if there is failure of the first lighting unit, to use the second lighting unit to generate the first automotive light signal. This is in response to an output request from the first lighting unit (10,12,14,16).
