Description

[Detailed description of the invention] [Technical field] The present invention is a single-ended fluorescent lamp whose light source is a single-ended fluorescent lamp in which an arc tube such as a U-shaped fluorescent lamp is bent and the bent arc tube axis forms approximately one plane. This article relates to gold fluorescent lighting equipment.

[Background technology]

Single-cap fluorescent lamp lighting equipment uses a U-shaped fluorescent lamp, which is a type of single-cap fluorescent lamp, as a light source.
Glyph-shaped fluorescent lighting equipment is well known, but the first
As in the case of the direct-mounted U-shaped fluorescent lamp lighting fixture shown in the figure, the U-shaped fluorescent lamp 1 is installed parallel to the lighting fixture main body 2, and the U-shaped fluorescent lamp 1 is installed parallel to the lighting fixture body 2, and is , while light is emitted over the entire length of the tube of the U-shaped fluorescent lamp 1, only approximately half of the total length of the tube is emitted to the sides, and therefore the front side of the lighting equipment There is a big difference in the brightness of the sides,
There were cases where the irradiation of light onto the mounting surface was insufficient. Also, it is necessary to install electrical components such as a ballast on the inside of the lighting fixture body 2, but if you want to prevent the shadow of the electrical components from appearing on the shade,
The U-shaped fluorescent lamp needs to be installed in front of the lighting device main body 2 relative to the electrical components, making it difficult to make the lighting device thin.

[Purpose of invention]

The purpose of the present invention is to improve the uniformity of light on the front and side surfaces of a lighting fixture, and to irradiate the mounting surface with sufficient light so that the mounting surface is not dark.

[Disclosure of invention]

The following explanation will be given based on the embodiment shown in FIG. The lighting equipment main body 2 is formed of a thin steel plate into a substantially rectangular tray shape, and a ballast 3 and a glow socket 4 are installed on the inner surface.
At the same time, a U-shaped fluorescent lamp socket 6 is provided, which is attached to a socket base 5 which is formed into a substantially L-shape from thin sheet metal and fixed near one end of the lighting fixture main body 2, and is connected to each other by wiring. It is connected and ready to light up. When the U-shaped fluorescent lamp 1 is attached to the U-shaped fluorescent lamp socket 6, the surface where the U-shape of the tube of the U-shaped fluorescent lamp 1 exists is aligned with the lighting fixture main body 2.
The U-shaped fluorescent lamp 1 is installed diagonally so as to intersect at an angle of about 45 degrees with the U-shaped fluorescent lamp 1, and the light from the U-shaped fluorescent lamp 1 is emitted almost equally to the front and sides. A shade 7 is attached to the lighting fixture body 2 to cover the front and side surfaces, and is mainly made of a translucent material to control light.

[Effect of idea]

According to the present invention, since the plane formed by the bent arc tube axis of the single-cap fluorescent lamp intersects the plane on the inner surface of the lighting fixture body at a non-perpendicular angle, it is easy to equalize the light to the front and side surfaces of the lighting fixture. In addition, the mounting surface does not become dark, and the shadows of the electrical components are less likely to appear on the shade, allowing the lighting fixture to be made thinner.
