Abstract
The utility model aims to solve the problem of the conventional integrated lamp tube bracket for a fluorescent lamp that electromagnetic interference is serious due to space restriction and electrified two ends of the conventional integrated lamp tube bracket. The integrated lamp tube bracket provided by the utility model comprises a bracket housing; two power supply plugs are respectively arranged at two ends of the bracket housing, and are communicated with each other through a supply lead concealed in the bracket housing; a filter circuit, a rectification circuit and an electronic ballast main circuit are also arranged in the bracket housing; one of the power supply plugs is conducted with the filter circuit, the rectification circuit and the electronic ballast main circuit sequentially; and a shielding plate or a shielding case used for separating the electronic ballast main circuit from the supply lead is arranged outside the electronic ballast main circuit, and is provided with a metal layer. Through the adoption of the integrated lamp tube bracket, electromagnetic interference on a circuit can be effectively eliminated from the source of the electromagnetic interference. The integrated lamp tube bracket has the advantages of simple structure and low cost, can be matched with fluorescent tubes with various specifications, and is suitable for mass production in factories.
Description
Technical field
The utility model relates to a kind of integrated tube stand of room lighting purposes.
Background technology
The integrated tube stand of the fluorescent lamp that has in the market is to be connected in series installation in the mode of head and the tail butt joint between many supports, as shown in Figure 1 and Figure 2.Such support all is provided with the connector head at the two ends of its rack shell, and (a common end is the connector male, the other end is the connector female), can be communicated with by the power supply lead wire that is hidden in rack shell inside between the connector head, make to obtain power supply from a end, as shown in Figure 3 at preceding tube stand at the back tube stand.
But, the integrated tube stand that some volumes are tiny, as the T5 support, because its inner each circuit arrangement and conductor mounting are very compact, so that power supply lead wire need pass through on the electric ballast main circuit more than the 20KHz in operating frequency.Because the electric ballast main circuit is very strong to the electromagnetic interference that power supply lead wire produces, and then influence is in the electricity consumption of back tube stand, so such tube stand need suppress the electromagnetic interference that the electric ballast main circuit is produced.
Yet the present solution that proposes at the electromagnetic interference phenomenon of the integrated tube stand of fluorescent lamp and few, the technical scheme that can reach national 3C electromagnetic interference standard-required much all is that cost is very high or the production difficulty is very big, has no idea substantially to drop into and promotes.In view of this, the integrated tube stand of developing a kind of low cost and can effectively suppressing electromagnetic interference is very necessary, and the development of illuminating industry is significant.
Summary of the invention
The serious problem of caused electromagnetic interference that the utility model is intended to overcome the existing integrated tube stand of fluorescent lamp because spatial constraints and two ends switch on proposes a kind of technical scheme that can address this problem well.
Integrated tube stand comprises rack shell, respectively is provided with a connector head at the two ends of rack shell, is communicated with by the power supply lead wire that is hidden in rack shell inside between the two connector heads; Also be provided with filter circuit, rectification circuit and electric ballast main circuit in the inside of rack shell; One of them connector head also with filter circuit, rectification circuit and the conducting successively of electric ballast main circuit; The barricade or the radome that are used to separate electric ballast main circuit and power supply lead wire that have metal level in one of the outer setting of described electric ballast main circuit.
The electromagnetic interference that barricade or radome can be produced the electric ballast main circuit shields isolation, prevents that electromagnetic interference from exerting an influence to the power line that is used to be communicated with two ends connector head, and then has guaranteed in the electricity consumption of back tube stand interference-free.
Above-described barricade or the radome that has metal level can adopt multilayer material to make, as: the PCB copper-clad plate; Also can adopt monolayer material to make, as: metallic plates such as single layer aluminium sheet.
Above-described filter circuit can be " L " type, " ∏ " type, two " ∏ " type or their combination, and the filter circuit of various expansions.
The utility model can effectively stop the influence of electromagnetic interference to circuit from the source of electromagnetic interference.And simple in structure, with low cost, can carry out supportingly with the fluorescent tube of all size, be applicable to factory mass production.

The specific embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As shown in Figure 4, the integrated tube stand of present embodiment comprises rack shell 1, is provided with connector female 2 at an end of rack shell 1, is provided with connector male 3 at the other end of rack shell 1.Connector female 2 is communicated with connector male 3 by power supply lead wire 4.Power supply lead wire 4 is in the rack shell 1.In rack shell 1, also be provided with filter circuit 5, rectification circuit 6 and electric ballast main circuit 7.Connector female 2 also is communicated with by lead successively with filter circuit 5, rectification circuit 6 and electric ballast main circuit 7.Barricade 8 at the aluminum of outer setting of electric ballast main circuit 7, electric ballast main circuit 7 and power supply lead wire 4 are separated, made to produce directly influence to power supply lead wire 4 by the electromagnetic interference conductively-closed of electric ballast main circuit 7 generations.
What this specification was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under operation principle of the present utility model and thinking all are considered as protection domain of the present utility model.
