Terminal block structure for fluorescent lamps {THE TERMINAL STRUCTURE OF A LAMP}

The present invention relates to the configuration of a 2P 3P terminal block applied to a ballast configured to operate two fluorescent lamps, and more specifically, to the cathode pieces connecting the cathode wires of the power supply among the terminal pieces installed inside the terminal block. It consists of two separate first and second negative electrode pieces, and the first and second negative electrode pieces have their own first and second terminal switches for the connection and short circuit of the power supply. A negative electrode control switch capable of selectively connecting or shorting the separated first and second negative electrode pieces may be provided so that both terminal switches simultaneously turn on and off two fluorescent lamps when the two negative electrode pieces are connected. In case of shorting of two cathodes, two terminal switches can turn on and off only one fluorescent lamp respectively. In addition to the function of the basic individual terminal switch that controls only one fluorescent lamp, the switch can be switched to the main switch that can turn on and off all fluorescent lamps at the same time, eliminating the separate main switch configuration, simplifying the terminal block configuration. It is intended to reduce the manufacturing cost and ease of manufacture.

Unlike incandescent bulbs, fluorescent lamps generally require lighting devices, but they are the mainstream of light sources because of their high light quality, high efficiency, economical efficiency, and easy handling. Recent fluorescent lamps are not limited to straight pipes or circuit lines, but are produced in various forms such as U-shape and bulb-type, and can be selected and used according to the use.They are divided into glow starter and electronic starter methods according to the lighting method of fluorescent lamps. do.

As a lighting device for lighting such a fluorescent lamp, there are a lighting circuit using an electronic ballast and a lighting circuit using a magnetic ballast.

While the lighting circuit using the electronic ballast can turn on a fluorescent lamp immediately at the initial "on" of the power switch, there is a problem that it is very expensive and puts a lot of economic burden on the user.

In addition, the lighting device using the magnetic ballast turns on a little later than the electronic ballast when the power switch is turned on, but is relatively inexpensive and widely used.

In the case of only one fluorescent lamp apparatus as described above, a large number of lighting structures that can be applied to a plurality of fluorescent lamps are known so that illumination intensity of the lighting may be changed according to necessity.

On the other hand, ballasts are applied to fluorescent lamps to allow high voltages to initiate discharge and stable currents during operation. These ballasts facilitate the interconnection of conductors such as cables, such as wiring connections and arrangements between devices and external circuits. In order to provide a terminal block used for the purpose, the terminal block is basically provided with a power connection terminal and a grounding terminal, and the number of terminal pieces is proportional to the number of fluorescent lamps applied.

On the other hand, Figure 3 shows a conventional configuration of the 2P 3P terminal block for applying two fluorescent lamps of the terminal block, the positive and negative wires and the ground wire of the power supply is connected to the three terminal pieces of the terminal block (T '), respectively, this terminal block (T The positive and negative poles of the power output from ') are applied to the ballast (A) and are applied to the positive ends of two fluorescent lamps (LAMP1) and (LAMP2) connected to the ballast (A). It is the structure which puts main switch SW.

On the other hand, a structure that can be turned off and off independently using a plurality of fluorescent lamps using individual switches is known as Utility Publication No. 1998-19592 as shown in Figure 4 and the structure thereof is as follows.

The terminal block (T ") electrically connected to the ballast (A) consists of a total of seven terminal pieces, three of which are connected to the positive and negative wires and the ground wire of the power supply, and the other four are two fluorescent lamps (LAMP1) (LAMP2). One side of the electrode is configured to be connected.

The other electrodes of the two fluorescent lamps LAMP1 and LAMP2 are connected to the ballast A through individual switches SW2 and SW3, and the cathode of the power supply is connected to the terminal block T ″ through a separate main switch SW1. It can be powered up or shorted.

However, in the structure of the former shown in FIG. 3 among the existing structures having the above structure, the main switch SW is the only switch capable of controlling the dot and the extinguishing of two fluorescent lamps LAMP1 and LAMP2. During operation, two fluorescent lamps (LAMP1) (LAMP2) must be turned on and off at the same time. Therefore, even when the illumination is not required, both fluorescent lamps are turned on, causing a waste of power.

In addition, if one dares to use only one fluorescent lamp, one of the fluorescent lamps can be pulled out from the socket while the main switch SW is turned on to turn off the lamp, which causes inconvenience in handling and waste of power.

In addition, the latter structure of FIG. 4 may control two fluorescent lamps individually through individual switches SW2 and SW3, but each individual switch SW2 and SW3 may be turned on and off only for one fluorescent lamp. In addition, since there is no function to turn on / off both fluorescent lamps at the same time, the main switch (SW1) which short-circuits or connects the power connected to the terminal block (T ") is additionally configured for this function. There was a problem of increasing the complexity of the structure and manufacturing cost.

The present invention is designed to solve all the problems caused by the existing structure as described above,

The present invention can be switched to a main switch that can switch on and off all fluorescent lamps at the same time as a basic individual terminal switch that controls only one fluorescent lamp, thus eliminating a separate main switch configuration, simplifying the configuration of the terminal block. It is an object of the present invention to provide a terminal block structure for fluorescent lamps that can be made and the manufacturing cost and manufacturing cost can be reduced.

The present invention to achieve the above object,

Of the terminal pieces installed inside the terminal block, the cathode pieces connecting the cathode wires of the power supply are composed of two first and second cathode pieces separated from each other, and the first and second cathode pieces are provided for connection and short circuit of the power supply. The first and second terminal switches of the independent, characterized in that the negative electrode control switch that can selectively connect or short-circuit the separated first and second negative electrode pieces.

As described above, the present invention is capable of simultaneously switching all fluorescent lamps in addition to the function of a basic individual terminal switch that controls only one fluorescent lamp through a negative electrode control switch that can selectively connect or short-circuit the first and second cathode pieces separately configured. By switching to a main switch that can be turned off, a separate main switch configuration can be eliminated, thereby simplifying the configuration of the terminal block, and it is a useful design having the effect of reducing the ease of manufacture and manufacturing cost.

Hereinafter, the configuration of the subject innovation in detail based on the accompanying drawings as follows.
