Description

TECHNICAL FIELD The present invention relates to a lighting device for a ring-shaped fluorescent lamp.

2. Description of the Related Art FIG. 4 shows a conventional example of a hanging type fluorescent lamp for a fluorescent lamp, which is generally used as an indoor lighting apparatus.
In the figure, (1) is a circular instrument body, (2)
(2 ') is two ring-shaped fluorescent lamps held by a plurality of lamp holders (3) (3) ... under the instrument body (1),
Reference numeral (4) is a shade placed on the main body (1) of the instrument, which surrounds the ring-shaped fluorescent lamps (2) and (2 ').

The instrument body (1) is formed by stacking an inverted dish-shaped body (1a) made of sheet metal and a dish-shaped reflector (1b) made of sheet metal. The instrument body (1) has a ring-shaped fluorescent lamp (2) ( 2 ') built-in lighting means,
As shown in Fig. 5 which is a bottom view of the reflective shade (1b),
Heat dissipation holes (5), (5) ..., Mounting holes (7) for security balls (6), Mounting holes (9) for two glow balls (8), (8) in the periphery
(9) is formed, and the drawstring (10) for blinking the lamp is hung from the center of the reflective shade (1b). A cord case (11) is fixed to the central portion of the upper surface of the main body (1a) of the appliance main body (1), and a power cord (12) extends upward from here, and the whole of the ceiling is secured by the power cord (12) [Fig. (Not shown).

Problems to be Solved by the Invention Although the above-described lighting fixtures brighten the indoor atmosphere and are widely used as the main lighting fixtures in the room, the lower surface of the fixture body (1) has a heat dissipation hole (5) and a safety bulb ( 6), glow ball (8)
The unevenness of (8) is unsightly, and there is a problem that it can be seen from directly under the lighting fixture and the appearance from the bottom of the lighting fixture is deteriorated. Further, the security bulb (6) is lit so as not to disturb the sleep of the person, but when the eyes of the person get accustomed to the dark room, the person feels the light of the security bulb (6) dazzling. was there.

Means for Solving the Problems In view of the above problems, as a means for solving the problems, the present invention is directed to a circular instrument body having a drawstring that hangs in a central portion, and an annular shape disposed below the instrument body. A fluorescent lamp, a substantially U-shaped mounting bracket arranged on the lower surface of the central portion of the appliance body, a funnel-shaped outer surface that covers the lower surface of the appliance body, and has an outer surface that reflects the light of the fluorescent lamp downward, and the center A translucent cover having a drawstring insertion hole in a portion thereof, and the cover is attached to the mounting bracket so that the cover and the peripheral portion of the lower surface of the instrument body are detachably attached, and the cover is attached. There is provided a lighting fixture in which a drawstring is led out from the insertion hole of the.

Action The cover is a translucent milk semi-colored resin product or glass product, and by covering the lower surface of the instrument body with this cover,
The heat dissipation holes and safety balls on the bottom surface of the fixture body are hidden by the cover, and the appearance from below the lighting fixture is further improved. Also,
When a safety ball is attached to the lower surface of the main body of illumination, the light of the safety ball is transmitted through the translucent cover, so that the glare of the illuminated security ball is reduced.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

The lighting fixture of FIG. 1 is obtained by applying the present invention to the lighting fixture of FIG. 4, and the same or corresponding portions as those of FIG. The difference is the instrument body (1)
Only the following cover (13) is attached to the lower surface of the.

The cover (13) is a funnel-shaped, light-transmissive, semi-milky resin molded product, for example, and is attached to the lower surface of the reflector (1b) of the instrument body (1) with a certain gap, for example, with the mounting bracket (14) It can be attached and removed freely with the metal fittings (15). This cover (13) has three claw pieces (16) protruding upward at 120 ° intervals on the upper end (13a) of the large diameter opening.
, And the lower end (13b) of the small-diameter opening is cylindrical,
Here, the decorative metal fitting (15) is inserted.

The mounting bracket (14) is substantially U-shaped as shown in FIG. 3, and the cylindrical screw (17) is fixed below the central portion (14a), and both upper end portions (14b) (1
4b) is screwed and fixed to the lower surface of the reflection shade (1b) of the instrument body (1) with screws (18) and (18). The decorative metal fitting (15) consists of a spherical lower part (15a) and a cylindrical upper part (15b).
(15a) (15b) penetrating hole (19) of the drawstring (10) is formed, the screw on the outer periphery of the upper part (15b) the cylindrical screw (17) of the mounting bracket (14) Is formed.

The cover (13) is attached to the lower surface of the instrument body (1) as follows. First, the mounting bracket (14) is screwed and fixed to the lower surface of the reflection shade (1b). Then, pass the drawstring (10) through the tube screw (17) of the mounting bracket (14), and further, lower end (1) of the cylindrical opening of the cover (13).
Pass the drawstring (10) through (3b) and open the lower end (13b) of this opening.
The cylindrical screw (17) of the mounting bracket (14) is inserted into, and the claw pieces (16) of the cover (13) are applied to the peripheral edge of the lower surface of the reflection shade (1b). Next, pass the drawstring (10) through the decorative metal fitting (15), and insert it from the lower end (13b) of the opening of the cover (13) and the cylindrical screw (17) into the cylindrical screw (17) and the cylindrical shape of the decorative metal fitting (15). Screw the upper part (15b), and the metal fittings (15)
The lower end portion (13b) of the opening of the cover (13) is sandwiched by the mounting bracket (14) and the cover (13) is pressed against the reflecting shade (1b) to be fixed.

In this way, the cover (13) mounted under the reflection shade (1b) has a function of the reflection shade that reflects the light of the fluorescent lamps (2) (2 ') downward, and a heat dissipation hole on the lower surface of the reflection shade (1b). It has a function of covering the (5), the safety ball (6), and the glow ball (8) (8) to improve the appearance from the bottom of the instrument body (1). In addition, by forming the cover (13) with a translucent resin such as milky color, the light of the safety bulb (6) is mitigated by passing through the cover (13), thereby realizing a dazzling nightlight. It

The present invention is not limited to the above-described embodiment, and in particular, the structure for attaching the cover to the instrument main body is not limited to the one using a dedicated mounting metal, and, for example, a locking claw is provided integrally with the cover, and this locking claw is used. It may be adapted to be directly attached and attached to the lower surface of the instrument main body.

EFFECTS OF THE INVENTION According to the present invention, it is possible to provide a luminaire having a high value-added product, in which the lower surface of the luminaire main body is covered with a cover and has a good appearance from below. In addition, in a lighting fixture having a safety bulb attached to the lower surface of the main body of the fixture, the light of the safety bulb is moderated by the cover, and a lighting fixture having the function of a nightlight that is not dazzling can be provided.
