Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to lighting equipment, and relates to attaching parts to a lighting equipment body formed from a molded product.

[Background technology]

When attaching electrical parts such as a glow starter to a lighting fixture body made of a molded product, you can attach them using other parts such as screws, or insert them into the locking parts provided on the lighting fixture body. Previously, the main body was held in place by frictional force due to its elasticity, but the number of parts increases when attaching it with other parts.On the other hand, the lighting equipment itself has a draft angle due to the molding process, and the elasticity of the lighting equipment main body When locking using frictional force, the parts to be locked tend to come off due to the draft angle of the locking part of the lighting fixture body. It is necessary to provide an undercut at the locking part of the lighting fixture, but it is difficult to provide an undercut at the locking part where parts such as a glow starter are attached inside the lighting fixture body, and the mold is too small. This method was difficult to adopt because it could become complicated and increase costs.

[Purpose of invention]

The purpose of this invention is to use lead wires to connect electrical components to ensure that components can be mounted inside the lighting equipment body without increasing the number of components or providing undercuts. .

[Disclosure of invention]

The lighting device according to the present invention has a substantially gutter-like component holder that stores a lighting electrical component made of a molded product and elastically fits and holds the component into a lighting device body to which a lamp support component is attached. A lead wire holding groove that elastically holds the lead wire and has a lead wire holding groove that is slightly narrower than the lead wire that connects electrical components is referred to as the component holding groove. It is provided parallel to and adjacent to the upper end of the component holder, and the lead wire is inserted and locked into the lead wire holder and the lead wire retaining groove is expanded to reduce the opening width at the upper end of the component holder. By using lead wires to connect the parts, it is possible to reliably attach the parts inside the lighting fixture body without increasing the number of parts or providing undercuts.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5.

The lighting fixture main body 1 is formed of a molded product in a substantially bowl shape, and has support parts 3, 3 provided near the lower end of the side surface at positions that are symmetrical to each other and through which the lamp support 2 is inserted and supported. The electrical parts for lighting the lamp are housed inside. The base base 4 has a base 5 that is screwed into the socket holder at the center of the upper surface of a molded product formed into a substantially rectangular shape.
It is fixed to the lighting fixture main body 1 so as to close the top opening, and the base 5 and the electrical components inside the lighting fixture main body 1 are connected with lead wires. The lamp support 2 is formed of a molded product, and is slidably supported by inserting a hook-shaped tip into the support portion 3 of the lighting fixture body 1 to prevent it from coming off.
The other end of the semicircular shape protruding from the round fluorescent lamp 6 is pressed against the symmetrical inner circumferential surface of the round fluorescent lamp 6 by the spring force of a spring 7, thereby holding the round fluorescent lamp 6. The glow starter 8 is provided with ribs 15 protruding parallel to each other at intervals of approximately the same width as the diameter of the glow starter at approximately the center of the lighting equipment main body to form an approximately gutter-shaped component holding section 9 through an opening on its upper surface. It is attached to the lighting fixture main body 1 by being inserted and elastically fitted. Ribs 16 are provided near the holding part 9 on the bottom surface of the lighting fixture main body 1, facing the tip of the lamp support 2 and facing the ribs 15 of the holding part 9, at approximately equal intervals to the spring diameter, and forming a seat for the spring 7. This is a spring holding part 10 which is a component holding part that is fitted and locked, and locks the spring 7. The tips of the ribs 15 of the holding part 9 holding the glow starter 8 are connected to the glow starter 8, respectively.
The lead wire holder 12 holds the lead wire 11 of the lead wire 11.

The lead wire holding portion 12 has a lead wire holding groove at the tip of the rib 15 and is roughly gutter-shaped. The groove is narrower than the lead wire 11 and has a bottom located above the position where the side surfaces of the glow starter 8 and holding portion 9 abut, and is deep enough for the lead wire 11 to fit completely in it.

Also, glow starter 8 and noise prevention capacitor 1
A partition wall 14 is provided between the glow starter 8 and the noise prevention capacitor 13 to position the glow starter 8 and separate the lead wires of different polarities of the glow starter 8 and the noise prevention capacitor 13 to ensure an insulating distance. When assembling this lighting fixture, the glow starter 8 is fitted into the holding part 9 of the lighting fixture main body 1 and attached by frictional force, while the seat part of the spring 7 is fitted and locked into the spring holding part 10, and then, The lead wire 11 is attached to the lead wire holding part 1
2, the lead wire is compressed by the groove of the lead wire holding part 12 which is narrower than the lead wire 11, and the side wall of the lead wire holding part 12 is expanded laterally, and the holding part 9 and the spring holding part The opening 10 is narrowed to prevent the glow starter 8 and the spring 7 from coming off, so that the glow starter 8 and the spring 7 are securely held and attached.

[Effect of idea]

According to the present invention, the approximately gutter-shaped component holding portion accommodates the lighting electrical component formed of a molded product and elastically fits and holds the component in the lighting fixture body to which the lamp support component is attached. The lead wire holding groove elastically holds the lead wire and has a lead wire holding groove that is slightly narrower than the lead wire connecting between electrical components, and the lead wire holding groove is approximately parallel to the component holding portion. In addition, it is provided adjacent to the upper end of the component holder, and by inserting and locking the lead wire into the lead wire holder and pushing out the lead wire retaining groove, the upper end opening width of the component holder is reduced and the component is prevented from falling out. By using lead wires to connect electrical components, components can be securely installed inside the lighting fixture without increasing the number of components or creating undercuts. .
