BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge lamp device, and more particularly to a discharge lamp device capable of easily cutting the length of the discharge lamp according to the length of the discharge lamp.

[0002]

2. Description of the Related Art For example, discharge lamps used for illuminating merchandise display shelves need to be of various lengths so as to be able to adapt to differences in the length of merchandise display shelves. Conventionally, such discharge lamps having different lengths at millimeter intervals have been prepared.Therefore, as a discharge lamp device for supplying power to both poles of such a discharge lamp, changing the length of the discharge lamp, etc. It is known that the length can be easily cut down so that it can be quickly responded to.

[0003] Conventionally, such a discharge lamp apparatus has a power transmission line having a substantially U-shaped cross section made of a conductor, which is extended with its open side up over the entire length of a base made of an insulator. Tool, having a contact inserted into the power transmission path of the transmission tool and a socket portion connected to the electrode of the discharge lamp,
A connector that conducts between the electrode of the discharge lamp and the power transmission path of the transmitter, and the connectors are fixed to both ends of the transmitter, and the power supplied to one of the connectors is transmitted to the transmitter. Is transmitted to the other connector via the power transmission path, thereby lighting the discharge lamp provided between the socket portions of both the connectors.

[0004] Since this discharge lamp apparatus is composed of a transmission tool and a connection tool which can be connected to and disconnected from each other, the dimensions can be easily adjusted by reducing the length of the transmission tool. Since the power transmission path is provided, there is an advantage that wiring can be omitted. Also, in a case where a plurality of discharge lamps are arranged in a line and lighted (hereinafter, such a lighting method is referred to as “continuous line lighting”), the plurality of discharge lamps are arranged in a line. It is possible if each transmission tool is electrically connected. In this conventional discharge lamp device, the electrical connection between the transmission devices is performed by a cord having connection plugs at both ends.

[0005]

In the above-described conventional discharge lamp apparatus, since the power transmission path having a substantially U-shaped cross section of the transmission tool is exposed, the human body is connected to the power transmission path when electricity is conducted. It is conceivable that an electric shock may be caused by touching a part of the power transmission line, or dust or the like may accumulate in the power transmission path. Further, since the power transmission path is substantially U-shaped, when cutting the transmission tool, burrs are likely to occur at the joint between the base of the cut surface and the power transmission path.

When the discharge lamps are to be lit in a continuous row, it is desirable to make the distance between the discharge lamps as small as possible so as to reduce the dark portions generated between the discharge lamps. In a conventional discharge lamp device, since a cord with a plug is used for electrical connection between the transmission devices, the interval between the discharge lamps becomes large, so that many dark areas are easily generated, and the number of parts is large. Become.

The present invention has been made in view of the above problems, and in a discharge lamp apparatus capable of cutting and adjusting the length, it is possible to suppress the occurrence of burrs on the cut surface and to prevent electric shock. It is an object of the present invention to provide a discharge lamp device which can reduce the number of parts and reduce the dark portion by narrowing the interval between discharge lamps when lighting in a continuous row.

[0008]

According to the present invention, there is provided a discharge lamp device according to the present invention, which supports an elongated discharge lamp and supplies electric power supplied to one end of the discharge lamp to the other end. A discharge lamp device for transmitting light to the discharge lamp to transmit light to the base, and a power transmission path having a hollow cross-section made of a conductor that is insulated and covered all around the base and extends inside the base over the entire length of the base. A transmission tool comprising: a male contact inserted into the power transmission path; and a socket portion connected to an electrode of the discharge lamp and supporting the discharge lamp. A pair of end connectors fixedly supported by the transmission tool at both ends of the transmission tool, and supplying power to one of the pair of end connection tools. And a power supply device.

According to another aspect of the present invention, there is provided a discharge lamp apparatus which supports a plurality of elongated discharge lamps arranged in a line and includes one of the discharge lamps. A discharge lamp device for transmitting power supplied to the other discharge lamps to light the respective discharge lamps, comprising: a base, a conductor extending in the base over the entire length of the base and covered with an insulating coating over the entire circumference; And a plurality of transmission tools arranged in a linear manner, and a front end of the transmission tool arranged at the forefront of a row of the transmission tools arranged in a line. And a male contact that is fixedly supported by the transmission tool at a rear end portion of the transmission tool disposed at the end of the row and is inserted into the power transmission path, and is connected to the electrode of the discharge lamp. And a socket portion for supporting the discharge lamp, and the power of the discharge lamp is provided. And a pair of end connectors that conduct between the power transmission line, a male contact inserted into the power transmission line, and an electrode of the discharge lamp to support the discharge lamp. A socket portion is provided at each end of the housing to conduct between the electrode of the discharge lamp and the power transmission path, and is disposed between the transmission tool and the transmission tool. An intermediate connector for electrical connection;
A power supply device for supplying power to any of the end connector and the intermediate connector.

[0010]

As described above, in the discharge lamp apparatus according to the first aspect of the present invention, since the power transmission path extending in the base of the transmission tool over its entire length is hollow in cross section, the transmission tool is cut off. When cutting the length to cut, easy to cut,
Moreover, burrs are less likely to occur on the cut surface. In addition, since the power transmission path is coated with an insulating material, it is possible to prevent a human body from touching the power transmission path to which electricity is conducted, to prevent electric shock, and to prevent dust or the like from adhering to the power transmission path.

Further, as described above, in the discharge lamp device according to the second aspect of the present invention, since the power transmission paths extending over the entire length in the base of each transmission device are both hollow in cross section, When cutting to reduce the length, cutting is easy and burrs hardly occur on the cut surface. In addition, since the power transmission path is coated with an insulating material, it is possible to prevent a human body from touching the power transmission path to which electricity is conducted, to prevent electric shock, and to prevent dust or the like from adhering to the power transmission path. Also,
The connection between the transmitters is performed by an intermediate connector having a socket and a male contact at both ends of the housing, so that a cord with a plug which has been conventionally used is unnecessary. As compared with the case of connection, the interval between the transmission tools can be significantly narrowed, whereby the dark portion between the discharge lamps can be reduced.
