Abstract
The utility model discloses a double colour bar switch lamp series circuit structure which realizes the color changing of a double-colour LED lamp by adding a current direction control circuit composed of a toggle switch and a commutation diode in the passage of the double-colour LED lamp. The circuit structure is simple, and can realize the color changing of the double-colour LED lamp through realizing the control on the current direction of the double-colour LED lamp circuit by controlling the switch in the toggle switch to be connected with different contacts through two commutation diodes with different directions and connected with the two contacts of the toggle switch. The structure does not need complex circuit structure, and greatly increases the attractiveness and practicability of the LED lamp.
Description
Technical field
The utility model relates to LED lighting circuit field, especially a kind of double-colored belt switch lamp string line structure.
Background technology
The LED lighting bulb in the application of every field is more and more widely compared with traditional bulb and energy-saving bulb, and the LED bulb has long service life, need not consider heat radiation and the advantage of environmental protection.The LED lighting bulb has the trend that replaces conventional bulb and energy-saving bulb gradually.In the present LED lighting field, realize that the bulb variable color generally needs complicated circuit, increased the volume of LED lamp greatly, influenced the aesthetic property and the practicality of LED lamp.
The utility model content
The purpose of this utility model provides a kind of double-colored belt switch lamp string line structure, can effectively realize the variable color of dual-colored LED lamp by sense of current control circuit.
In order to achieve the above object, the technical scheme that the utility model adopted is:
Double-colored belt switch lamp string line structure, include the electric current input lead, plug before the corresponding LED lamp of described electric current input lead one end, the tail plug of the corresponding LED lamp of the other end, the dual-colored LED circuit for lamp that the dual-colored LED lamp formation of a plurality of mutual series connection is arranged between the described electric current input lead, terminals of described dual-colored LED circuit for lamp are connected on the electric current input lead, it is characterized in that: also include the sense of current control circuit that toggle switch and rectifier diode constitute, the switch terminal of described toggle switch is connected to another root electric current input lead by lead, described toggle switch has two contacts, be electrically connected with a rectifier diode on the described contact respectively separately, described rectifier diode closure difference, after two rectifier diodes were parallel with one another, another terminals that are connected to described dual-colored LED circuit for lamp by lead constituted current circuit.
The utility model circuit structure is simple, two different rectifier diodes of the both direction that the contact connected by toggle switch, switch in the control toggle switch connects different contacts, control can be realized, and then the variable color of dual-colored LED lamp can be realized the sense of current that passes through the dual-colored LED circuit for lamp.The utility model does not need complicated circuit structure, has increased the aesthetic property and the practicality of LED lamp greatly.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Embodiment
As shown in Figure 1.Double-colored belt switch lamp string line structure, include electric current input lead A, B, plug before the corresponding LED lamp of electric current input lead B one end, the tail plug of the corresponding LED lamp of the other end, electric current input lead A, the dual-colored LED lamp LED1 that a plurality of mutual series connection are arranged between the B, LED2, the dual-colored LED circuit for lamp that LED3 constitutes, terminals of dual-colored LED circuit for lamp are connected on the electric current input lead B, also include toggle switch K and rectifier diode D1, the sense of current control circuit that D2 constitutes, the switch terminal of toggle switch K is connected to another root electric current input lead A by lead, toggle switch K has two contacts, be electrically connected with a rectifier diode D1 on the contact respectively separately, D2, rectifier diode D1, D2 closure difference, two rectifier diode D1, after D2 was parallel with one another, another terminals that are connected to the dual-colored LED circuit for lamp by lead constituted current circuit.
As Fig. 1 the utility model circuit theory diagrams, its operating voltage is 120V60HZ, this circuit structure according to dual-colored LED when the direct current by different directions, it has different color performances, two rectifier diode D1 among the figure, D2 links to each other with two contact points of toggle switch K respectively, by rectifier diode D1, the adjustment of the direction of D2, and utilize rectifier diode D1, the effect of the halfwave rectifier that D2 reaches, thereby the alternating current that inserts is changed into the direct current of half-wave state, the direction of while Control current, it has 2 opposite direct currents of direction when getting to up and down two different positions to make switch, change the luminous of double-colored bulb thereby reach control lamp string flow path direction, thereby reach the effect of lamp string variable color.
When toggle switch during at shown position, under the effect of rectifier diode D2 halfwave rectifier below, the sense of current of this lamp string is for to be inserted into preceding direction interpolation from tail, the color conducting of dual-colored LED corresponding current direction;
When toggle switch is dialled up, by top rectifier diode D1 halfwave rectifier, the sense of current becomes and is inserted into tail in the past and inserts, thereby changes the sense of current by dual-colored LED, changes the color of dual-colored LED, reaches the effect that becomes light.
