Abstract

The utility model discloses an electronic section ballast with an annular tube, which comprises a ballast module, a ballast control circuit connected with the ballast module and an external switch connected with the ballast control circuit. The ballast module is composed of a first ballast and a second ballast, the first ballast and the second ballast are respectively connected with the ballast control circuit and controlled by the ballast control circuit, and the ballast control circuit is also connected with the external switch and controlled by the external switch. By implementing the electronic section ballast with the annular tube, because two ballasts are positioned in the identical ballast module, and controlled by the control circuit connected with the ballast, the startup, shutdown and cross exchange functions of two ballasts are realized. Moreover, the ballast control circuit is also connected with the external switch and controlled by the external switch, thereby people can securely realize the transforming and controlling of each luminous tube only by operating the external switch. The electronic section ballast with the annular tube has advantages of easy transformation and control among a plurality of luminous tubes, and simple and safe operation.

Description

Ring-like pipe electronics segmentation ballast

Technical field

The utility model relates to a kind of ballast, particularly relates to a kind of electronics segmentation ballast.

Background technology

At present, fluorescent lamp well is widely used because of it is energy-conservation, luminous, and ballast then is the requisite device of daylight illumination.During build-up of luminance (moment that starter disconnects), ballast can produce a higher self-induced e.m.f and a supply voltage superposition, makes lamp tube ends obtain higher starting voltage; It is connected with fluorescent tube as a retardation coil behind the build-up of luminance, makes the voltage of lamp tube ends be dropped to rated value.Ring-like pipe fluorescent lamp generally is spliced by several sections fluorescent tubes, and existing ballast is difficult to realize conversion and the control between a plurality of fluorescent tubes, therefore presses for a kind of ring-like pipe electronics segmented ballast that can realize conversion and control between a plurality of fluorescent tubes.

The utility model content

The utility model is the shortcoming according to prior art, provides a kind of simple in structure and be easy to the ring-like pipe electronics segmentation ballast of conversion and control between a plurality of fluorescent tubes.

The utility model is achieved through the following technical solutions: a kind of ring-like pipe electronics segmentation ballast comprises ballast module, the ballast control circuit that is connected with described ballast module, the external switch that is connected with described ballast control circuit.

Described ballast module is made of first ballast and second ballast, and it is connected with described ballast control circuit respectively, and for its control, ballast control circuit is connected with external switch again, controlled by it.

Implement the utility model, following beneficial effect is arranged: by two ballasts are placed in the same ballast module, and the ballast control circuit that is attached thereto controls, thus realize two ballasts startup, close the function with cross exchanged.And ballast control circuit links to each other with external switch, and controlled by it, thereby people only need just can realize conversion and control to each fluorescent tube safely by the operation to external switch.A kind of ring-like pipe electronics segmentation ballast like this is easy to conversion and control between a plurality of fluorescent tubes, simple to operate, safety.

Description of drawings

Fig. 1 is the structure chart of the ring-like pipe electronics of the utility model segmentation ballast;

Fig. 2 is the structure chart of a specific embodiment of the ring-like pipe electronics of the utility model segmentation ballast.

Embodiment

Below in conjunction with accompanying drawing the ring-like pipe electronics of the utility model segmentation ballast further is described in detail.

As shown in Figure 1, the utility model is made of ballast module 2, ballast control circuit 1 and external switch 3.

As shown in Figure 2, in a specific embodiment of the present utility model, ballast module 2 is made of first ballast 21 and second ballast 22, and first ballast 21 and second ballast 22 are common ballast circuit structure, are made of filter circuit and oscillating circuit.First ballast 21 and second ballast, 22 each self-contained coil, the coil of first ballast 21 twines around first central shaft, and the coil of second ballast 22 twines around second central shaft.Because it is placed on the same printed circuit board (PCB), for avoiding the electromagnetic interference between the coil, first central shaft and second central shaft need perpendicular.First ballast 21 links to each other with ballast control circuit 1 respectively with second ballast 22, receives the signal that is passed over by ballast 1, and controlled by it.

Ballast control circuit 1 comprises the multi-functional block switch of HL2608 type, this block switch is the core component of the ring-like pipe electronics of the utility model segmentation ballast, conversion between the multitube that the utility model is realized mainly realizes by multi-functional block switch of this HL2608 type and ballast module with control, the multi-functional block switch of HL2608 type can realize that first ballast 21 works independently, or second ballast 22 work independently, or first ballast 21 and second ballast 22 work or first ballast 21 and the 22 exchange work of second ballast simultaneously.

External switch 3 links to each other with ballast control circuit 1, people can select the working method of ballast module 2 by external switch, as first ballast 21 work independently, second ballast 22 works independently, first ballast 21 and the 22 exchange work of second ballast or first ballast 21 and second ballast, 22 co-operation.

Above disclosed only is the preferred embodiment of the ring-like pipe electronics of the utility model segmentation ballast, certainly can not limit the interest field of the utility model with this, therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
