The invention relates to an automobile
signal lamp LED electronic control module. The automobile
signal lamp LED electronic control module comprises an LED string, a
driving circuit of the LED stringand a circuit board on which the LED string and the
driving circuit are arranged, wherein the LED string comprises one or multiple LED which are connected in series, the circuit board covers a top surface of a radiator and is further fixedly bonded on the top surface of the radiator through a
radiation glue layer, the radiator is provided with a sinker, the sinker opening is arranged at the top surface of the radiator, a power device of the
driving circuit is mounted below the circuit board and is arranged in the sinker, other electronic devices of the driving circuit and the LED are mounted on the circuit board, a lower portion of the radiator is provided with a
radiation structure and a connection lead or a connector inlet port of a PIN needle, and the driving circuit employs a DCDC typedriving circuit BUCK topological structure. The automobile
signal lamp LED electronic control module is advantaged in that
miniaturization and
standardization requirements are satisfied on the condition that the optical
system attenuation requirement is satisfied, and one
LED lamp module is made to be suitable for all
signal lamp body structures.
