摘要： The apparatus of a progressive direction indicator, especially for a car headlight or lamp, comprises the main connector (1) as the input electric interface, an LDM power supply module (2) for the power supply of the LED light sources (7), an LED board (4) where the LED light sources are mounted, and an interface (3) interconnecting the LDM power supply module with the LED board. The apparatus further comprises a current controller (9) for setting the current of the LED light sources, with the LDM power supply module comprising a DC/DC converter (5) generating the output voltage V out, which is the voltage source for the LED board. The LED board comprises discrete switching elements (8) for switching of individual LED light sources depending on the input voltage, so that the LED light sources are sequentially switched depending on the output voltage V out.

摘要： The detection system comprises a light unit to emit light, a primary optical unit to process light, a main light stream exiting therefrom directed to the mirror unit comprising micromirrors arranged in a rotary way whose angle of rotation is controlled by the control system so that light intended to produce a light image at a particular moment is reflected by the respective micromirrors, while the part of the light that shouldn't be used to produce the light image at the particular moment is reflected by other micromirrors into an absorption unit, from where light rays continue into the detection unit with an optical sensor to detect light rays, and a control unit to process the signal from the optical sensor, to evaluate whether the established condition corresponds to the pre-established light characteristic that the respective micromirror (or group(s) thereof) would exhibit during its faultless activity.
