Description

Description: TECHNICAL FIELD The present invention relates to a lighting fixture.

2. Description of the Related Art Conventionally, in a fluorescent lamp luminaire, a ballast for stably lighting a fluorescent lamp, a glow socket, a bead ball socket, and a switch are arranged inside the main body of the device, and each is electrically connected by an electric wire. The fluorescent lamp sockets that are electrically connected to each other and that are arranged outside the instrument body are also electrically connected to the circuit section in the instrument body by electric wires.

There was also a lighting device in which a wiring component made of a composite component in which a miniature ball socket, a glow socket, and a switch were integrated was used to connect to a ballast without using an electric wire. (See, for example, Japanese Utility Model Application Publication No. 56-51216) [Problems to be Solved by the Invention] In the former fluorescent lamp lighting equipment, there are many operations of connecting electric wires to each component (for example, soldering), and assembling work is troublesome. Was. In addition, since there are many electric wires, there are problems that connection mistakes are likely to occur and that the inside of the main body of the device is complicated by electric wires.

Further, in the latter conventional example, the wiring components are sandwiched between the ballast and the cover of the appliance main body. However, there is a problem in that no power is applied to the printed circuit board of the lighting block on which the electronic components are mounted due to fear of cracking. As with the former, the fluorescent lamp socket also comes with wires, and the wiring components are not fixed to the chassis side of the fixture body, and there are problems such as stress applied to the wiring components depending on the height variation of the left and right ballast terminals. Was.

The present invention has been made in view of such problems,
Provided is a lighting device capable of electrically connecting a lighting block in which electronic components are arranged on a printed circuit board and a wiring component including a lamp socket without using an electric wire, and in which the wiring component can be assembled from one direction. Another object of the present invention is to provide a lighting device in which a lamp holder and a wiring component can be easily replaced, and in which a power is hardly applied to an electric connection portion on a printed circuit board side when the lamp holder and the wiring component are installed. An object of the present invention is to provide a lighting fixture in which electronic parts are not exposed when the cover is removed.

[Means for Solving the Problems] In order to achieve the above object, in the lighting fixture of the present invention, a block configured by mounting electronic parts of a lighting circuit for stably lighting a fluorescent lamp on a printed board is provided. A switch for switching loads including a fluorescent lamp, a wiring component such as a socket for mounting a miniature ball, and a lamp holder having a socket portion for holding the fluorescent lamp and supplying electric power are provided on the main body of the apparatus. , Insert the electrical connection part provided on the printed circuit board and the electrical connection part provided on the wiring part and the lamp holder so that they are at the same height when the printed circuit board, the wiring part and the lamp holder are attached to the fixture body. After the connection, the main body cover that covers the lamp holder, the lighting block, and the wiring parts is attached to the main body of the fixture so that the socket portion is exposed to the outside. Things.

In particular, it is preferable to provide an opening for mounting the wiring component and the lamp holder on the printed circuit board so that the wiring component and the lamp holder can be mounted on the device main body after the printed circuit board is mounted on the device main body.

Also, to prevent unreasonable force from being applied to the electrical connection part of the printed circuit board during installation, the wiring parts and the lamp holder device main body should receive the force during installation to the device main body of the lamp holder. A fixing member for positioning is formed.

Further, the printed circuit board may be installed so that the mounting area of the electronic component of the lighting circuit is the instrument body side so that the electronic component is not exposed when the body cover is removed.

[Operation] In the lighting fixture of the present invention, after the printed circuit board is attached to the fixture main body, when the wiring component is attached to the fixture main body via the attachment opening formed in the printed board, the electrical connection of the printed board is simultaneously performed. Part and the electrical connection part of the wiring device are electrically connected, and at the same time as assembling, electrical connection between the lighting block and the wiring part and electrical connection between the lighting block and the socket part of the lamp holder can be performed without an electric wire. At this time, since the positioning and fixing member receives the wiring component and the lamp holder, no force is applied to the electric connection portion of the printed board.

The luminaire of the present invention is completed by attaching the main body cover after attaching the member to the main body of the luminaire.

Wiring parts such as sockets for mounting the lamp and a lamp holder having a socket part for holding and supplying electric power to the fluorescent lamp are mounted on the fixture body, and a printed circuit board, wiring parts and a lamp holder are mounted on the fixture body. The electrical connection part provided on the printed circuit board and the electrical connection parts respectively provided on the wiring part and the lamp holder are inserted and connected so that they are at the same height in the above state, and the socket part is exposed to the outside. Since the holder, the lighting block and the main body cover that covers the wiring parts are attached to the main body of the fixture, the parts can be assembled in the same direction. To improve the assemblability, and the lamp holder,
Electrical connection can be performed without using wires at the same time as installing wiring parts and lighting blocks, so automatic assembly is possible, and since there is no need to use wires for connecting the socket part to connect the fluorescent lamp, the appearance This has the effect of not becoming ugly. In addition, by providing an opening for mounting the wiring component and the lamp holder on the printed circuit board so that the wiring component and the lamp holder can be mounted on the device main body after the mounting of the printed circuit board on the device main body, the lamp holder and the wiring component are provided. Can be replaced regardless of the lighting block, and the wiring parts and the lamp holder are positioned and fixed to the fixture body so that the fixture body receives the force when the wiring components and lamp holder are attached to the fixture body. Since the members are formed, it is difficult to apply a force to the electrical connection portion on the lighting block side during assembly, and peeling of the connection portion between the printed circuit board and the electrical connection portion does not occur, so that reliability of connection is improved. Furthermore, if the printed circuit board is installed with the mounting surface side of the electronic components of the lighting block facing the main body of the fixture, the electronic components of the lighting block will not be exposed when the body cover is removed, and there is no risk of touching and damaging them. Since the pattern surface of the printed circuit board faces downward when the device is mounted, there is no accumulation of dust, and the occurrence of insulation failure due to moisture absorption by dust is unlikely to occur.
