Abstract
The utility model provides a large power LED dimming driver, which is a device for light source regulation and control of the LED. The driver is provided with a single chip microcomputer which is connected to a DMX-512, and the single chip microcomputer processes control protocol of the DMX-512, which decodes signal of the DMX-512 to output three-way PWM signal, and the three-way PWM signal is output to a three-way constant current driving circuit which outputs three-way constant current to adjust brightness of the LED light of the red, the green and the blue. The utility model has the advantages of being compatible with the control protocol of the DMX-512, which outputs the constant current of 350mA and innovates the wide voltage of 6-48V to be the widest in present 350mA constant current products.
Description
Technical field
The utility model relates to the device that a kind of LED light source is regulated, controlled.
Background technology
The regulating and controlling of LED light source has multiple mode, still, does not also have to adopt DMX-512 light control protocol commonly used at present, the constant-flow driver of control LED.
Summary of the invention
In order to address the above problem, the utility model provides a kind of great power LED dimming driver, this driver is provided with a single-chip microcomputer and is connected with DMX-512, handle the DMX-512 control protocol, that is: accept outside DMX-512 control signal, decoding DMX-512 signal also produces three road pulse-width signals, exports three road constant-current drive circuits to, export three road continuous currents, adjust the brightness of red, green, blue led light source.
Three road constant-current drive circuits, produce direct current 78V voltage by built-in switching power circuit, supply power IC3843, an energy storage inductor, metal-oxide-semiconductor and the constant-current drive circuit that adds the fast recovery diode composition, the 78V direct current of switching power circuit generation is converted to the 350mA constant current output of 6-48V, high frequency (less than the 10M hertz) pulse-width signal that while produces according to outside (for example unit), switch the output of constant current or do not export, for three road 350mA constant current output modules output 350mA constant current, voltage range is 6-48V, and constant-current drive circuit is mainly added metal-oxide-semiconductor and added fast recovery diode by 3843 power supply IC and an energy storage inductor and forms.
The utility model has the advantages that compatible DMX-512 light control protocol is exported stable 350mA constant current, the wide voltage of innovation 6-48V is output as in the present 350mA constant-current driving product the wideest.
