Detailed description of the invention
Please refer to Fig. 4, the detailed description of the invention of a kind of LED eon light of the utility model bar is described.
A kind of LED eon light bar, after its several LED lamp adopts series connection, parallel way is connected to direct current supply voltage two ends, each LED lamp is connected with a mu balanced circuit, this mu balanced circuit is connected in parallel on the direct current supply voltage two ends of the control IC of LED lamp, the digital controlled signal of the square-wave signal of an external load different duty, the digital controlled signal of this external load by transmission line from the LED lamp of the low-voltage end of supply voltage, be transferred to the control IC of each LED lamp of LED eon light bar one by one, a series connection coupling capacitance on signal transmission line between two adjacent LEDs light fixture, namely first coupling capacitance is connected by the signal input part of signal transmission line with first LED lamp, the signal output part of first LED lamp is connected with the signal input part of second light fixture by second coupling capacitance, the signal output part of second light fixture is connected with the signal input part of the 3rd LED lamp by the 3rd coupling capacitance, the like, be connected to the signal input part of last LED lamp always, the coupling capacitance that signal transmission line is connected can intercept direct current supply voltage, realize the control of digital controlled signal to each LED lamp, ensure that the normal work on digital controlled signal not ground altogether, because adopting for electric energy of LED lamp is connected or parallel way after series connection, connect the LED lamp of same quantity, supply line's main line electric current can greatly reduce, line drop is corresponding to diminish, loss reduces greatly, requiring power bus neither be very high, can not cause and power not and form the technical problem that obvious color distortion affects display effect, therefore, just solve power bus band well and carry the technical problem that the quantity of LED lamp can not be too many.
The voltage amplitude value of the digital controlled signal that said external loads does different designs according to different product, the digital controlled signal of external load also can provide from the LED lamp of the high voltage end of direct current supply voltage, successively by each LED lamp, signal control is carried out to each LED lamp, coupling capacitance described above can be integrated in each LED lamp, several LED lamp of LED eon light bar also can adopt the independent mode that is connected in series to power, and mu balanced circuit also can be integrated in each LED lamp.
The magnitude of voltage sum of all mu balanced circuits in the LED lamp of mutual series connection is designed to the direct current supply magnitude of voltage being equal to or slightly less than whole LED eon light bar, now provided with the application of a 12V direct current supply voltage, each LED lamp uses the voltage-stabiliser tube of a 3.8V, the wiring using the common ground mode of Fig. 1 is example, the electric current of each LED lamp is 60mA, connect 300 LED lamp, total electric current is 60mA*300=18A, need very thick power bus to power and could meet so large electric current, and line drop and loss also very large; If with the mode of connection of the present utility model, 3 LED lamp are a string, and then in parallel, separate by coupling capacitance between LED lamp, ensure that the normal work of control signal, such bus current is (300/3) * 60mA=6A, electric current reduces to original 1/3, if 6 LED lamp are a string, and then in parallel, the electric current of such bus is (300/6) * 60mA=3A, and bus current will be original 1/6.
The above, be only detailed description of the invention of the present utility model, is not intended to limit protection domain of the present utility model.
