摘要： LED driver circuit for powering at least one LED string comprises: at least one lighting switching element (TLEDA; TLEDB), connected to the LED string and operable to switch at least between an inactive state, in which it prevents the passage of a driver current (ILED) into said LED string, and an active state, in which it imposes a driver current (ILED) through said LED string, The driver current is dependent on a driver voltage (Vref) applied to the lighting switching element. The circuit further comprises switch driver circuit means (10, 20, 40) suitable for generating a driver voltage (Vref) which depends in a substantially linear manner on the power supply voltage (VDD).

摘要： An automotive light is provided that includes a light-guide bar made of photoconductive-material, which is at least partially positioned substantially grazing a corresponding transparent or semitransparent portion of the front lenticular half-shell of the light, and a second light source which is structured so as to emit light when electricity powered, and is arranged inside the rear body, close to one end of the light-guide bar, so as to direct the light produced inside the body of said light-guide bar. The light-guide bar is provided with a longitudinal light-extractor band which extends along the lateral side of the bar, and a multitude of deflector prisms which have an approximately triangle-shaped cross-section and are conveniently arranged along the longitudinal light-extractor band. One or more deflector prisms are shaped so that the active deflector surface has a bulging/arched profile substantially over the whole width of the longitudinal band.
