Description

Novel duplex control circuit of LED lamp

Technical Field

The utility model relates to a control circuit, in particular to novel control circuit of LED lamps and lanterns pair.

Background

The LED lamp duplex control circuit is more and more widely used at present, relates to civil use and industry, and a double-control switch is selected mainly because the double-control switch has the greatest characteristic of being capable of remotely controlling lamps or electric appliances. For example, in daily life, when a person enters a door, the lights in the living room are turned on, when the person enters a bedroom, the lights in the living room are turned off, and in industrial aspects, such as the use of the lights in an elevator shaft, when the lights in the living room are turned on, the lights in the living room are turned off below a pit, or vice versa. If the lamp is turned off by returning to the place where the lamp is turned on according to the traditional mode, the trouble can be avoided after the double-control switch is adopted, and the use is convenient. The traditional double-control switch circuit adopts 4 wires for wiring, as shown in figure 1, the traditional double-control switch circuit is relatively complex in wiring, large in wire consumption and high in wiring cost, and the traditional lighting adopts a single lamp design, so that once a lamp fails, the lighting function is completely lost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a novel control circuit of LED lamps and lanterns pair that simple structure, wiring cost are low, excellent in use effect.

The utility model adopts the technical proposal that: the utility model discloses a relay KA, first single-pole double-throw switch K1, second single-pole double-throw switch K2, lamps and lanterns LED, relay KA has two coil terminals, a common terminal, normally open contact, a normally closed contact, one of them coil terminal of relay KA with the common terminal of relay KA all is connected with live wire L, another coil terminal of relay KA with one of them motionless end of second single-pole double-throw switch K2 is connected, normally open contact of relay KA with the normally closed contact of relay KA respectively with two motionless ends of first single-pole double-throw switch K1 are connected, the common terminal of first single-pole double-throw switch K1 with lamps and lanterns LED's input is connected, lamps and lanterns LED's output reaches second single-pole double-throw switch K2's common end all is connected with zero line N.

Further, the relay KA is an HF115-A type relay.

Further, the lamp is an LED lamp.

Furthermore, the LED lamp is formed by connecting a plurality of LED lamps in parallel.

Further, the first single pole double throw switch K1 and the second single pole double throw switch K2 are boat type switches.

The utility model has the advantages that: because the utility model adopts the design of relay duplex control, the utility model comprises a relay KA, a first single-pole double-throw switch K1, a second single-pole double-throw switch K2 and a lamp LED, the relay KA has two coil terminals, a common terminal, a normally open contact, a normally closed contact, one of the coil terminals of the relay KA and the common terminal of the relay KA are both connected to a live line L, the other coil terminal of the relay KA is connected to one of the stationary terminals of the second single-pole double-throw switch K2, the normally open contact of the relay KA and the normally closed contact of the relay KA are respectively connected with the two immovable ends of the first single-pole double-throw switch K1, the common terminal of the first single-pole double-throw switch K1 is connected with the input terminal of the lamp LED, the output end of the lamp LED and the common end of the second single-pole double-throw switch K2 are both connected with a zero line N. Therefore, the utility model has the advantages of simple structure, low wiring cost and good use effect.
