Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to lighting equipment.

[Prior Art] Conventionally, fluorescent lighting equipment includes a ballast for stably lighting a fluorescent lamp, a glow socket, a miniature bulb socket,
A switch is placed inside the appliance body and electrically connected to each other by an electric wire, and a fluorescent lamp socket placed outside the appliance body is also electrically connected to a circuit section inside the appliance body by an electric wire.

There were also lighting devices that connected to the ballast without using electric wires by using a wiring component that was a composite component that integrated a small bulb socket, a glow socket, and a switch. (See, for example, Japanese Utility Model Application Publication No. 56-51216) [Problems to be solved by the invention] In the former type of fluorescent lamp lighting equipment, there is a lot of work (for example, soldering) to connect electric wires to each part, and the assembly work is difficult. there were. Furthermore, since there are a large number of wires, wiring errors are likely to occur, and the inside of the device body becomes cluttered with the wires.

In addition, in the latter conventional example, the wiring components are held between the ballast and the cover of the device body, but there is a problem in that no force can be applied to the printed circuit board of the lighting block, which is equipped with electronic components, for fear of cracking. Ta. Like the former, the socket for the fluorescent lamp also comes with an electric wire, and the wiring parts are not fixed to the chassis side of the device, and there are problems such as stress being applied to the wiring parts depending on the height variation of the left and right ballast terminals. Ta.

The present invention has been made in view of these problems, and it is possible to electrically connect a lighting block with electronic components arranged on a printed circuit board and wiring components including a lamp socket without using electric wires. The aim is to provide lighting equipment where the wiring parts can be assembled from one direction, and the lamp holder and wiring parts can be easily replaced (also, when installing the lamp holder and wiring parts, electrical connections on the printed circuit board side can be made easily). To provide a lighting fixture in which force is not easily applied to the parts thereof, and further to provide a lighting fixture in which electronic parts are not exposed when the main body cover is removed.

[Means for Solving the Problems] In order to achieve the above object, the lighting device of the present invention includes a lighting block configured by mounting electronic components of a lighting circuit on a printed circuit board for stably lighting a fluorescent lamp. and,
Wiring parts such as a switch for switching the load including the fluorescent lamp, a socket for attaching the miniature bulb, and a lamp holder having a socket part for holding the fluorescent lamp and supplying power are arranged on the main body of the appliance, and an electrical connection part provided on the printed circuit board so that the printed circuit board, wiring components, and lamp holder are at the same height when scattered in the main body of the device;
Connect the wiring parts and the electrical connection parts provided on the lamp holder by inserting them, and attach the main body cover to the main body of the appliance so as to expose the socket part to the outside, and cover the lamp holder, the lighting block, and the wiring parts. This is what I did.

In particular, it is preferable to provide the printed circuit board with openings for installing wiring components and lamp holders so that the wiring components and lamp holders can be installed in the appliance body after the printed circuit board is installed on the appliance body.

In addition, in order to prevent excessive force from being applied to the electrical connections of the printed circuit board during installation, the wiring parts and the lamp holder should be placed in the appliance body in such a way that the force when installing the lamp holder on the appliance body is received by the appliance body. This is to form a positioning and fixing member.

Furthermore, in order to prevent the electronic components from being exposed when the main body cover is removed, it is preferable to arrange the printed circuit boards so that the electronic component mounting surface of the lighting circuit is on the appliance main body side.

[Function] In the lighting equipment of the present invention, after the printed circuit board is installed in the equipment main body, when the wiring components are installed in the equipment main body through the installation openings formed in the printed circuit board, the electrical connection of the printed circuit board is simultaneously established. The part and the electrical connection part of the wiring device are electrically connected, and the lighting block and the wiring part can be electrically connected to each other and the lighting block and the socket part of the lamp holder can be electrically connected without wires at the same time as assembly.

[Effects of the Invention] The present invention provides a lighting block configured by mounting electronic components of a lighting circuit on a printed circuit board for stably lighting the above-mentioned fluorescent lamp, a switch for switching a load including the fluorescent lamp,
Attach wiring parts such as a socket for attaching a miniature bulb and a lamp boulder having a socket part that holds a fluorescent lamp and supplies power to the fixture body, and then attach a printed circuit board, wiring parts, and lamp holder to the fixture body. Insert and connect the electrical connection part provided on the printed circuit board and the electrical connection parts provided on the wiring component and lamp holder respectively so that they are at the same height when installed, and the socket part is exposed to the outside. Since the body cover that covers the lamp holder, lighting block and wiring parts is attached to the main body of the appliance, each part can be assembled in the same direction, improving assembly efficiency. Electrical connections can be made at the same time as parts and lighting blocks are installed without using electric wires, making automatic assembly possible.
Moreover, since no electric wire is used to connect the socket portion to which the fluorescent lamp is connected, there is an effect that the appearance does not become ugly. By providing openings for installing wiring parts and lamp holders on the printed circuit board so that wiring parts and lamp holders can be installed on the equipment body after the splint board is attached to the equipment body, lamp holders and wiring parts can be installed. It can be replaced regardless of the lighting block, and the wiring parts and lamp holder are positioned and fixed on the fixture body so that the force when installing the wiring parts and lamp holder on the fixture body is received by the fixture body. Because of this, during assembly, force is applied to the electrical connection part on the lighting block side, and the connection part between the printed circuit board and the electrical connection part does not peel off, improving the reliability of the connection. Furthermore, if you install the printed circuit board with the side where the electronic components of the lighting block are mounted as the main/body side of the device, the electronic components of the lighting block will not be exposed when the main body cover is removed, and there is no risk of them being damaged by touching them. Also, since the pattern side of the printed circuit board faces downward when installing the equipment, there is no accumulation of dust.
Insulation failure due to moisture absorption by lumps is also less likely to occur.
