Description

  The present invention relates to an illumination lighting device and an illumination fixture having a mounting structure for attaching the illumination lighting device to the illumination fixture.

  In recent years, as a renewal of fluorescent lighting equipment, there has been a tendency to increase the number of businesses that replace only ballasts. This is because power can be saved at a lower cost than replacing all the lighting fixtures.

  A fluorescent lamp illuminator is mainly composed of a main body of metal or plastic, a ballast, a socket, and a fluorescent lamp. The fluorescent lamp that has the shortest lifetime among fluorescent lamp luminaires is a fluorescent lamp. There is no problem because the fluorescent lamp can be easily replaced when it has reached the end of its life and is no longer lit.

  The next shortest component is the ballast. Ballasts reach the end of their lives due to deterioration of insulators and electronic components. Continued use of ballasts with reduced insulation performance is not desirable for the safety of lighting fixtures.

  As the demand for renewal for the purpose of saving power or renewal due to the life of the ballast becomes stronger, it is important that the ballast can be easily replaced.

  FIG. 11 is an example of a type of lighting fixture in which the ballast 3 is attached to the base plate (top surface) of the lighting fixture 6, and FIG. 12 is a plan view of the ballast 3. A power supply line is connected to the input connector 1 of the ballast 3, and wirings (lamp lead wires) to the lamp socket S are connected to the output connectors 2a and 2b. Conventionally, attachment / detachment of the ballast 3 to / from the lighting fixture 6 has been performed by opening a mounting hole 11 in the base plate of the lighting fixture 6 and the ballast 3 and screwing them. At the time of replacement, an operation of screwing while holding the nut from the back side of the instrument must be performed, and workability is poor.

  Therefore, in order to improve work efficiency, for example, in Patent Document 1, a means for fixing the ballast to the tool by bending a cut and raised piece from the tool is used. Can be easily removed using a tool.

In Patent Document 2, a magnet is incorporated in the center and both ends in the longitudinal direction of the ballast, and the replacement work is simplified by using a means for fixing the ball by adhering it to an instrument made of a magnetic material. .

  By the way, in order to pursue power saving performance, reduce costs, and liberate the shape of the appliance, the size of the inverter ballast is in the direction of miniaturization. Progressing. Therefore, when replacing a ballast in a luminaire, the existing ballast and the new ballast are often different in size.

  In fact, when replacing the ballast, a new mounting hole is drilled in the instrument to match the size of the new ballast. In addition, it is often necessary to fix the ballast directly to the fixture using the tapping screw from the front side of the fixture while the fixture is attached, since the construction cost increases when the lighting fixture installed on the ceiling is removed and drilled. Done. Furthermore, even if the size of the ballast is the same, at the time of installation, an operation is performed in which the nut is pressed from the back side of the mounting hole while holding the nut.

  In order to facilitate replacement of the ballast, as disclosed in Patent Document 1, the means for fixing the ballast to the fixture by bending the cut-and-raised piece from the fixture is previously cut into the lighting fixture. It is necessary to provide a piece, and it is impossible to freely move the position of the cut and raised piece. That is, ballasts of different lengths cannot be attached to the same lighting fixture.

  When adsorbing with a magnetic material as in Patent Document 2, there is a high possibility that the ballast will drop due to vibration depending on the use environment of the ballast, and it is difficult to ensure reliability.

  When the fluorescent lamps to be connected are for two lamps, the connection method differs depending on the ballast, so the lamp lead wire or the like must be reconnected and connected to the ballast.

  FIGS. 13A to 13C show connection forms of the plurality of fluorescent lamps FL1 and FL2 to the ballast 3. FIG. Such rewiring for ballast replacement is troublesome and inconvenient, and may cause inconveniences such as short lamp life and heat generation when misconnection occurs.

  The present invention has been made in view of the above points, and it is possible to easily and surely attach and remove the ballast to the lighting fixture. In addition, the difference in dimensions and the connection between the lamp lead wires are different. The purpose of this ballast is to enable easy attachment to and removal from a lighting fixture.
