But the three-way four paths of LEDs lamp strings of continued access

Technical field

The utility model relates to LED lamp string.

Background technology

The modes that adopt five lines four tunnel in existing four paths of LEDs lamp decorations, this line-transect is many, complex structure, cost height more.

Summary of the invention

The utility model technical problem at first to be solved provides a kind of three-way four street lamps decorations that can finish five lines, four tunnel functions.For this reason, the utility model is by the following technical solutions: it comprises three power transmission lines, wherein be in series with a plurality of parallel circuits that composed in parallel by LED and diode respectively on two power transmission lines, the LED in the parallel circuit is opposite with the direction of diode, and the direction of the LED of adjacent parallel circuit is opposite.Owing to adopt technical solutions of the utility model, when directional current of input, have only that road energising identical in the parallel circuit and make this paths of LEDs luminous with this direction, another road no power does not work, and is staggered luminous thereby available three power transmission lines are realized four paths of LEDs that need five lines to realize in the LED lamp string in the past, thus, reduced by two main lines, reduced cost, structure becomes simply, but and is continued access.

For solving the problems of the technologies described above, the utility model also can adopt following technical scheme simultaneously, it can reach above-mentioned technique effect equally: it comprises three power transmission lines, wherein be in series with a plurality of parallel circuits that compose in parallel by LED and diode respectively on two power transmission lines, LED in the parallel circuit is opposite with the direction of diode, in a plurality of parallel circuits on every power transmission line, the direction of the LED that the LED in the part parallel circuit and remaining parallel circuit are interior is opposite.

But but another technical problem to be solved of the utility model provides a kind of LED lamp string that two-way replaces the continued access of lighting function that possesses on the wall scroll power transmission line.For this reason, the utility model by the following technical solutions: it comprises power transmission line, is in series with a plurality of parallel circuits that composed in parallel by LED and diode on the power transmission line, and the LED in the parallel circuit is opposite with the direction of diode, and the direction of the LED of adjacent parallel circuit is opposite.Owing to adopt technical solutions of the utility model, when directional current of input, have only that road energising identical in the parallel circuit and make this paths of LEDs luminous with this direction, another road no power does not work, thereby can realize on the wall scroll power transmission line that two paths of LED is staggered luminous, can reduce the cost of LED lamp string thus, its structure is become simply, but and be continued access.

For solving the problems of the technologies described above, the utility model also can adopt following technical scheme simultaneously, it can reach above-mentioned technique effect equally: it comprises power transmission line, be in series with a plurality of parallel circuits that compose in parallel by LED and diode on the power transmission line, LED in the parallel circuit is opposite with the direction of diode, in a plurality of parallel circuits on the power transmission line, the direction of the LED in the LED in the part parallel circuit and remaining parallel circuit is opposite.

Description of drawings

Fig. 1 is the circuit diagram of embodiment provided by the utility model.

The specific embodiment

With reference to accompanying drawing.The utility model comprises three power transmission lines 1,2,3, wherein is in series with a plurality of parallel circuits respectively on two power transmission lines 1,2.As shown in the figure, described parallel circuit is made up of the LED4 and the general-purpose diode 5 of parallel connection, and the LED4 in the parallel circuit is opposite with the direction of general-purpose diode 5, and the direction of the LED4 of adjacent parallel circuit is opposite, and wherein, LED is a light emitting diode.Like this, can select any street lamp bright, make adjacent LED loop staggered luminous, play the effect that reduces main line by controller, but and the main line continued access, the general-purpose diode in parallel with LED, effect is equivalent to resistance, and has athermic advantage.

LED4 and general-purpose diode 5 in the above-mentioned parallel circuit can be the split settings, also can adopt the form of monomer bipolar chip, promptly in LED monomer, and opposite polarity with it general-purpose diode in parallel, formation monomer bipolarity LED.

Above-described controller can adopt and anyly can switch forward and reverse sense of current, and making the electric current that enters parallel circuit is galvanic controller, and it is connected on the power transmission line 1,2, plays the effect of the control sense of current.

Can predict: can constantly connect on power transmission line 1,2 increases described parallel circuit; In parallel circuit, this road of LED is set, can as required a plurality of LED be set, as long as the direction of these LED is identical; In addition, not necessarily the direction of the LED of adjacent parallel circuit is opposite, need only in a plurality of parallel circuits on the every power transmission line, the direction of the LED that LED in the part parallel circuit and remaining parallel circuit are interior is opposite, can reach the luminous purpose of single power transmission line two-way equally, just along with the layout difference of parallel circuit, generation replace luminous visual effect difference.

Can predict,, can realize that equally two-way is luminous, reduce the purpose of the cost of LED lamp string even have only a power transmission line to adopt such scheme.That is: be in series with a plurality of parallel circuits that composed in parallel by LED and diode on this power transmission line, the LED in the parallel circuit is opposite with the direction of diode, and the direction of the LED of adjacent parallel circuit is opposite.Perhaps, on this power transmission line, be in series with a plurality of parallel circuits that compose in parallel by LED and diode, LED in the parallel circuit is opposite with the direction of diode, and in a plurality of parallel circuits on the power transmission line, the direction of the LED in the LED in the part parallel circuit and remaining parallel circuit is opposite.
