Abstract
The utility model aims to overcome the problem that the electromagnetic interference is serious because an integral lamp tube bracket of the present fluorescent lamp is limited by space and two ends are electrified, and provides a technical scheme to solve the problem well. An anti-interference integral lamp tube bracket includes a bracket casing, wherein an electronic ballast main circuit is arranged in the bracket casing, two power supply plugs are arranged at two ends of the bracket casing respectively, and the two power supply plugs are communicated at least through a live wire and a zero wire hidden inside the bracket casing; a magnetic ring is further arranged in the bracket casing, and the magnetic conductivity mur of the magnetic ring ranges from 100 to 7,000; and the live wire and the zero wire surround the magnetic ring for 0.5-15 circles. The anti-interference integral lamp tube bracket can inhibit high-frequency interference signals, and effectively avoid the influence of electromagnetic interference on a line. Moreover, the structure is simple, the cost is low, and the anti-interference integral lamp tube bracket can be matched with various specifications of fluorescent lamp tubes, and is suitable for production in batch in a factory.
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 electric ballast main circuit and the extraneous electromagnetic interference that 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.
Anti-interference integrated tube stand, comprise rack shell, be provided with the electric ballast main circuit in the inside of rack shell, respectively be provided with a connector head, be communicated with by live wire and the zero line that is hidden in rack shell inside at least between the two connector heads at the two ends of rack shell; Also be provided with magnet ring in rack shell, the magnetic conductivity μ r of magnet ring is between 100～7000; Described live wire and zero line are worn and are walked around magnet ring 0.5 circle～15 circles.
Through test, its effect that suppresses electromagnetic interference of integrated tube stand that power supply lead wire is done after the above-mentioned processing obviously strengthens.
Above-described magnet ring can be nickel zinc magnet ring and manganese-zinc magnetic ring.When adopting nickel zinc magnet ring, the magnetic conductivity μ r of magnet ring is preferably between 100～3500, and live wire and zero line are walked around magnet ring 0.5 circle～15 circles.When adopting manganese-zinc magnetic ring, the magnetic conductivity μ r of magnet ring is preferably between 500～7000, and live wire and zero line are walked around magnet ring 0.5 circle～15 circles.
Above-described filter circuit can be " L " type, or " ∏ " type, or two " ∏ " type or their combination, and the filter circuit of various expansions.
The utility model can suppress high-frequency interferencing signal, effectively stops the influence of electromagnetic interference to circuit.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 live wire 4, zero line 5.Live wire 4, zero line 5 are in the rack shell 1.In rack shell 1, also be provided with filter circuit 6, rectification circuit 7 and electric ballast main circuit 8.Connector female 2 also is communicated with by lead successively with filter circuit 6, rectification circuit 7 and electric ballast main circuit 8.
The live wire 4 that is used to be communicated with connector female 2 and connector male 3 of present embodiment, zero line 5 are worn simultaneously and are walked around a nickel zinc magnet ring 9, and wearing the pitch of the laps number is 1.5 circles, the magnetic flux μ r=1000 of nickel zinc magnet ring 9.Under the effect of nickel zinc magnet ring 9, no matter whether live wire 4 and zero line 5 alive, and the high-frequency signal on live wire 4 and the zero line 5 can both be suppressed effectively.
