Abstract
A multi-channel type LED driving power, comprises LED driving power, and LED driving power comprises the live wire input utmost point, zero line the input utmost point, anodal output stage and negative plate output stage; It is characterized in that: described LED driving power has several, the described live wire input utmost point is connected in parallel and is connected with live wire, and anodal output stage is connected in parallel; Zero line is inputted extremely parallel connection and is linked together with zero line together, and negative pole output-parallel together.Adopt such structure, adopt a plurality of LED driving power parallel waies, can prevent that in the circuit of LED driving power, certain electronic unit breaks down, and stop power supply, cause whole LED electroluminescent lamp groups to carry out lamp; Each driver module is shared smaller electric current, so greatly reduce the failure rate that LED drives, even if electronic devices and components break down, only can affect corresponding single driver module, all the other driver modules all can normally be worked, also only can reduce sub-fraction power carrys out work to LED light fixture, and there will not be the phenomenon of at once dead lamp, greatly extends the useful life of LED light fixture.
Description
Technical field
The present invention relates to a kind of LED light fixture, especially a kind of LED driving power of LED light fixture.
Background technology
Currently available technology, the life-span of high-power LED lamp is subject to the restriction that Led drives at present, makes Led can not give full play to the advantage of self.And at present on the market LED light fixture all adopt single pass high-power driving power supply, electric current in the time of this driving power work is large, cause self-heating serious, and electronic devices and components also will be born large electric current, cause failure rate high, once and certain electronic devices and components breaks down, can cause the phenomenon of the dead lamp of whole lamp.。
Summary of the invention
The object of the invention is: a kind of multi-channel type LED driving power is provided, and it can reduce single led driving power power, can bearing great current, and can prevent that certain electronic unit from breaking down and turning off the light.
The present invention is achieved in that a kind of multi-channel type LED driving power, comprises LED driving power, and LED driving power comprises the live wire input utmost point, zero line the input utmost point, anodal output stage and negative plate output stage; Its special character is: described LED driving power has several,
The described live wire input utmost point is connected in parallel and is connected with live wire, and anodal output stage is connected in parallel; Zero line is inputted extremely parallel connection and is linked together with zero line together, and negative pole output-parallel together.
Described a kind of multi-channel type LED driving power, its special character is: on described anodal output stage, be in series with diode.
Described a kind of multi-channel type LED driving power, its special character is: described LED driving power has three and joint group, first and the live wire input utmost point of joint group be connected with the first live wire, second and the live wire input utmost point of joint group is connected with the second live wire, the 3rd also the live wire of joint group input the utmost point and be connected with the 3rd live wire.
Described a kind of multi-channel type LED driving power, its special character is: on the live wire output stage of described LED driving power, be provided with switch.
A kind of multi-channel type LED of the present invention driving power, owing to adopting such structure, adopt a plurality of LED driving power parallel waies, can prevent that in the circuit of LED driving power, certain electronic unit breaks down, and stop power supply, cause whole LED electroluminescent lamp groups to carry out lamp; Each driver module is shared smaller electric current, so greatly reduce the failure rate that LED drives, even if electronic devices and components break down, only can affect corresponding single driver module, all the other driver modules all can normally be worked, also only can reduce sub-fraction power carrys out work to LED light fixture, and there will not be the phenomenon of at once dead lamp, greatly extends the useful life of LED light fixture.
Accompanying drawing explanation
Fig. 1 is one of block diagram of circuit theory of the present invention.
Fig. 2 be circuit theory of the present invention block diagram two.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of multi-channel type LED driving power, comprises LED driving power, and LED driving power comprises the live wire input utmost point, zero line the input utmost point, anodal output stage and negative plate output stage; Described LED driving power has several,
The described live wire input utmost point is connected in parallel and is connected with live wire L, and anodal output stage is connected in parallel; Zero line is inputted extremely parallel connection and is linked together with zero line N together, and negative pole output-parallel together.
As the present invention, further improve: on the anodal output stage of described LED power supply, be in series with diode D1, the anode of diode D1 is connected with the cathode output end of LED driving power;
As the present invention, further improve: in described live wire input extremely, be provided with K switch.
When the present embodiment is used, anodal output stage is connected with the positive pole of LED illuminating module, and negative pole output stage is connected with the negative pole of LED illuminating module; LED illuminating module has electrode input end to be in series with diode D2.
Embodiment 2
As shown in Figure 2, described LED driving power has three and joint groups, first and the live wire input utmost point of joint group is connected with the first live wire L1, second and the live wire input utmost point of joint group be connected with the second live wire L2, the 3rd also the live wire of joint group input the utmost point and be connected with the 3rd live wire L3.The zero line input of LED driving power is extremely connected with zero line N after parallel connection, negative pole output stage is in parallel.
On described anodal output stage, be in series with diode D1.
Input connects respectively the L1 of three-phase 380V electric wire, L2, L3, when needing to reduce Power operation so in the second half of the night, can realize reduction Power operation by cutting off one in three-phase mutually or two-phase, so just can realize almost 0 cost increases, realize the object that reduces after midnight Power operation, reach the effect of energy-saving and emission-reduction more.
Above-described is only preferential execution mode of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the principles of the present invention, can also make some improvement and modification, this is also considered as protection scope of the present invention.
