Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to lighting equipment.

[Conventional technology]

As an illuminator, a ring-shaped fluorescent lamp is supported on the bottom surface,
There is a type of fluorescent light that is covered with a globe.

The annular fluorescent light is engaged with and supported by a semi-annular part formed in a band-shaped leaf spring attached to the base plate, and the opening edge of the globe has a flange facing toward the outer circumference.
The tips of screws screwed into the board from three directions are locked to the flanges.

[Problem that the invention attempts to solve]

In order to attach the globe to the board, the globe is secured with screws screwed into the board from three directions, but if the globe is made of glass, damage may occur due to over-tightening of the screws.

The purpose of this invention is to provide a lighting fixture that does not have a glove locking screw and allows easy attachment and detachment of gloves.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention forms a tongue piece facing the outer circumference at the base of a band-shaped leaf spring that is attached to a base plate and has a semi-annular part for supporting a fluorescent lamp, This lighting device has a notch for releasing the tongue of the leaf spring at the opening edge of the globe on the substrate side.

[Effect]

To attach an annular fluorescent light to this luminaire,
In order to fit and support the fluorescent light into the semi-annular curved part of the bag-like leaf spring attached to the base plate and then attach the globe, a notch is formed in the opening edge of the globe to release the tongue of the leaf spring. Insert the tongue piece into the
By rotating the glove within a small range, the tongue moves to the edge of the opening where there is no notch and cannot be removed.

〔Example〕

In FIG. 1, reference numeral 1 designates a base plate from which a band-shaped leaf spring 2 for supporting an annular fluorescent lamp hangs down on three sides, and 3 a globe.

The band-shaped leaf spring 2 is formed with a semi-annular portion 5 for fitting and supporting an annular fluorescent lamp 4. In FIG. 2, 6 is the attachment part of the upper end of the leaf spring 2 to the board 1;
7 is a hole through which a mounting screw 8 is passed.

A tongue piece 9 facing toward the outer circumferential side is cut and raised at a portion near the upper end of the leaf spring 2.

Further, as shown in FIG. 3, the opening edge 10 of the glove 3 on the substrate 1 side is formed with notch recesses 11 on three sides for allowing the tongue piece 9 to escape. By rotating the glove within a small range with the tongue inserted into the glove 3, the tongue piece is prevented from coming out.

In FIG. 3, reference numeral 12 indicates a contact step of the tongue piece at a position away from the notch recess 11 of the opening edge 9.

〔effect〕

A tongue piece for glove engagement is cut and raised near the upper end of the band-shaped leaf spring, and a notch recess for releasing the tongue piece is formed at the opening edge of the glove, so that the tongue piece can be aligned with the notch recess. By inserting it into the glove and then rotating it within a small range, the tongue piece becomes a stopper, which not only makes it easy to put on and take off the glove, but also locks the opening edge flange of the glove with conventional screws. Since the globe is made of glass, there is no risk of damage due to over-tightening of screws.

Claims (1)

[Scope of utility model registration request] In a lighting device consisting of a substrate and a globe that support an annular fluorescent lamp, a tongue piece facing the outer circumference is cut and raised at the root of a band-shaped leaf spring that is attached to the substrate and has a semicircular part for supporting the fluorescent lamp. and a notch recess for escaping the tongue of the leaf spring is formed in the opening edge of the globe on the substrate side.
