Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of control circuit of LED lamp, by the technical program, can realize by different control LED lamp does not need to recognize that both positive and negative polarity powers, or is realized and controlled many group LED lamp groups by an input.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that
A kind of control circuit of LED lamp, include the rectification circuit of four diode D1, D2, D3, D4 formation, also include the first wire jumper contact K1, the second wire jumper contact K2, a LED1 lamp group and the 2nd LED2 lamp group, described the first wire jumper contact K1 and wire jumper contact K2 are separately positioned on input and the output of a LED1 lamp group and the 2nd LED2 lamp group, the one LED1 lamp group two ends are connected with the positive pole of diode D3 with the negative pole of diode D1 respectively, and the 2nd LED2 lamp group two ends are connected with the positive pole of diode D4 with the negative pole of diode D2 respectively.
Described the first wire jumper contact K1 and the second wire jumper contact K2 can select welding manner, jumper terminal or jumper switch according to actual needs.
A described LED1 lamp group and the 2nd LED2 lamp group are respectively several LED lamps that are in parallel or connect and form.
Adopt the beneficial effect after technique scheme to be: a kind of control circuit of LED lamp, by the technical program, can realize by different control LED lamp does not need to recognize that both positive and negative polarity powers, or is realized and controlled many group LED lamp groups by an input.
Accompanying drawing explanation
Fig. 1 is the utility model integrated circuit schematic diagram.
In figure, D1, D2, D3, D4 are that diode, K1 are that the first wire jumper contact, K2 are that the second wire jumper contact, LED1 are that a LED lamp group, LED2 are that the 2nd LED lamp group, A are that first input end, B are the second input.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model and specific embodiment are described further.
As shown in Figure 1, the control circuit of a kind of LED lamp that the utility model relates to, include four diode D1, D2, D3, the rectification circuit that D4 forms, also include the first wire jumper contact K1, the second wire jumper contact K2, the one LED1 lamp group and the 2nd LED2 lamp group, described the first wire jumper contact K1 and wire jumper contact K2 are separately positioned on input and the output of a LED1 lamp group and the 2nd LED2 lamp group, the one LED1 lamp group two ends are connected with the positive pole of diode D3 with the negative pole of diode D1 respectively, the 2nd LED2 lamp group two ends are connected with the positive pole of diode D4 with the negative pole of diode D2 respectively.
Described the first wire jumper contact K1 and the second wire jumper contact K2 can select welding manner, jumper terminal or jumper switch according to actual needs, and a described LED1 lamp group and the 2nd LED2 lamp group are respectively several LED lamps that are in parallel or several LED lamp being in series forms.
The utility model is when work:
When the first wire jumper contact K1 and the closed connection of the second wire jumper contact K2, diode D1, D2, D3, D4 form a rectifying full bridge circuit, now first input end A and the second input B above load alternating current or positive and negative direct current, the one LED lamp group LED1 and the 2nd LED lamp group LED2 can be light, this kind of status circuit can individualism, and can directly connect input, need not distinguish the positive-negative polarity of input A and input B.
When the first wire jumper contact K1 and the second wire jumper contact K2 disconnection, first input end A inputs anodal, and when the second input B inputs the direct current of negative pole, diode D1, D3, a LED lamp group LED1 form a loop, the one LED lamp group LED1 is bright, and the 2nd LED lamp group LED2 does not work and do not work; First input end A inputs negative pole, when the second input B inputs anodal direct current, diode D2, D4, the 2nd LED lamp group LED2 form a loop, the 2nd LED lamp group LED2 is bright, the one LED lamp group LED1 does not work and does not work, and this kind of status circuit can individualism solves the work brightness that the voltage of inputting different both positive and negative polarities by changing first input end A and the second input B is controlled a LED lamp group LED1 and the 2nd LED lamp group LED2.
When the multiple break-make by the first wire jumper contact K1 and the second wire jumper contact K2 combines, can form various independent independent circuits, to reach different needs.
The first wire jumper contact K1 in the utility model and the second wire jumper contact K2 can direct conducting form circuit by the mode of welding, also can adopt jumper terminal or jumper switch to realize.The one LED lamp group LED1 and the 2nd LED lamp group LED2 can be combined by several LED lamps under the various states of in parallel and series connection.
The above, only own for preferred embodiment of the present utility model, be not intended to limit protection range of the present utility model.
