Abstract
The utility model discloses a lighting circuit of LED lamps, which is composed of a plurality of groups of LED lamps which are serially connected, each group of the LED lamps is connected through connecting more than two rows of LED lamps in parallel, each row of the LED lamps is composed of one LED lamp or a plurality of LED lamps connecting in series. Under the same power voltage, the voltage and the current which are born by each LED lamp of the utility model are reduced, thereby the service life of the LED lamps is prolonged, the joint current of the circuit, namely the current passes through the power supply is reduced, thereby, the depletion and the heating of the power supply are reduced, though each group of the LED are connected in series, however, each group of the LED lamps are connected through connecting more than two rows of the LED lamps in parallel, even one row of LED lamps is broken, the power can be continuously conducted through the other rows, thereby the other LED lamps can not be affected to emit light, furthermore, even the LED lamps fails of emitting light, however, because of a special PN structure, the lighting circuit of LED lamps further comprises certain circuit conducting ability.
Description
Technical field
The utility model relates to a kind of lighting circuit, particularly a kind of lighting circuit of LED lamp.
Background technology
At present, the lighting circuit of general LED lamp is that the LED (light emitting diode) that several are single is connected in parallel between the power supply, so the shortcoming of connected mode is: the one, and each LED bears the whole voltage of power supply, and the single led electric current of flowing through is bigger, and easily reduce the service life of LED; The 2nd, the total current of circuit is each LED electric current sum of flowing through, and causes the total current of circuit to increase, and then the electric current of the power supply that is made of transformation, rectification circuit is increased, and makes the power supply heating, and loss increases.
Summary of the invention
The purpose of this utility model is the shortcoming that exists for the lighting circuit that solves above-mentioned existing LED lamp, and provide a kind of lighting circuit of LED lamp, the lighting circuit of this LED lamp reduces the total current of single led and circuit, and then reduces the loss and the heating of power supply, the service life of improving LED.
LED lamp of the present utility model is to be connected in series by many groups LED lamp to form, and every group of LED lamp is to be connected in parallel by the above LED lamp of two row to form, and every row LED lamp is to be made of or several LED are connected in series and form a LED.
The beneficial effects of the utility model are as follows:
1, under the identical situation of supply voltage, voltage that each LED bears and electric current reduce, and then the service life that can improve LED;
2, promptly the flow through electric current of power supply of the total current of circuit reduces, and then can reduce the loss and the heating of power supply;
Be connected in series though 3 respectively organize LED,, every group of LED lamp is to be connected in parallel by the above LED lamp of two row to form, even wherein a row LED lamp opens circuit, also can be listed as the LED lamp by other and continue turn-on power, can not influence other LED luminous lighting; In addition, not luminous even LED lost efficacy, still, because its special P N junction structure, it also has certain circuit turn-on ability.
Description of drawings
Fig. 1 is the circuit diagram of the utility model first embodiment.
The specific embodiment
See also shown in Figure 1ly, the utility model embodiment is connected in series by three groups of LED lamps 1 to form, and every group of LED lamp 1 is that the LED lamps 2 by two row are connected in parallel and form, and every row LED lamp 2 is to be connected in series by two LED3 to form.
When every row LED lamp 2 is just to have constituted the matrix form circuit when being made of a LED3.
Claims (2)
1, a kind of lighting circuit of LED lamp is characterized in that: be to be connected in series by many groups LED lamp to form, every group of LED lamp is to be connected in parallel by the above LED lamp of two row to form, and every row LED lamp is to be made of or several LED are connected in series and form a LED.
2, the lighting circuit of a kind of LED lamp according to claim 1 is characterized in that: be to be connected in series by three groups of LED lamps to form, every group of LED lamp is to be connected in parallel by the two LED lamps that are listed as to form, and every row LED lamp is to be connected in series by two LED3 to form.
