Abstract

PURPOSE:To reduce loss in light by removably equipping a reflecting board with a flat cover which covers a ballast provided on the reflecting board, forms a reflecting surface and does not protrude from a lamp mounted on a lamp socket. CONSTITUTION:On a flat reflecting board 1, a ballast 2 is attached in a space between a plurality of lamps provided in parallel opposite to the reflecting board 1, and a surface of the ballast 2 is covered by a reflecting surface formed on the reflecting board 1 so that a fixture can be assembled without using an apparatus body such as a chassis as well as the entire fixture can be flattened and thinned. In addition since the cover 10 is flat and does not protrude from a lamp 8 mounted on a lamp socket 6 as well as the surface of the cover 10 is formed on the reflecting surface so that the cover 10 does not make a shade. Further since the ballast 2 is placed in contact with or close to the reflecting board 1, heat radiation can be improved. Since the surface of the cover 10 is also formed in the reflecting surface, there is no loss in light and the ballast 2 and a mounting recess 3 are covered by the cover 10 thereby not deteriorating appearance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a lighting fixture, and for example, to a fixture that is attached to a ceiling surface or the like and is designed to be flat and thin.

(Prior art) Conventional lighting equipment of this type has a ballast housed in the main body, an opening in the main body covered with a reflector, and lamp sockets arranged opposite to each other at both ends of the reflector. A structure is adopted in which terminal pins protruding from both ends of the lamp are attached to the lamp socket, and the lamp is opposed to a reflector.

(Problems to be Solved by the Invention) In the above-mentioned conventional lighting device, the height increases by the height of the device body, which is an obstacle to making the device thinner.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a lighting fixture that can be made flat and thin.

[Structure of the invention]

(Means for Solving the Problems) A lighting fixture of the present invention includes a flat reflector, a plurality of lamp sockets attached to the reflective surface side of the reflector, and a plurality of lamp sockets attached to the lamp socket that reflect the reflectors of the reflector. The lamp includes a plurality of lamps arranged parallel to a surface, and a flat electronic ballast connected to the lamp socket, and the ballast is arranged between the plurality of lamps attached to the lamp socket and between the lamps. The reflector is a flat cover that is located between the sockets and is attached close to the reflector, covers the ballast attached to the reflector, has a reflective surface, and does not protrude beyond the lamp attached to the lampholder. It is removably attached to the board.

(Function) The lighting device of the present invention includes a flat reflecting plate, and a flat electronic ballast located in a space between a plurality of lamps arranged parallel to the reflecting plate and between lamp sockets. By attaching the ballast and covering the ballast with a flat cover with a reflective surface, the device can be assembled without using the main body of the device such as a chassis, and the entire device can be made flat and thin. Moreover, since the cover does not protrude beyond the lamp, it does not cast a shadow, and since the ballast is mounted close to the reflector, the heat dissipation effect can be enhanced.

(Example) The configuration of an example of the lighting fixture of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a rectangular flat plate-like reflector, and a rectangular flat electronic ballast 2 long in the longitudinal direction of the reflector 1 is mounted in the center in contact with or close to the surface of the reflector 1. ing. Recesses 3 are formed at both ends of the ballast 2, respectively. For this attachment, the bottom part 4 of the recess 3 is provided with a through hole 5 for screws or the like to be attached to a surface to be attached, such as a ceiling surface.

Further, two pairs of lamp sockets 6 are attached to both ends of the reflector 1, and the lamp sockets 6 are connected to each other between straight tube fluorescent lamps 8, each of which has a base 7 at both ends. The stabilizer 2 is arranged in the space.

Further, mounting holes 9 are formed in the reflecting plate 1 at a plurality of locations around the recess 3 and the mounting position of the stabilizer 2.

Reference numeral 10 denotes a flat cover that covers the stabilizer 2 and the recess 3, the surface of this cover 10 is formed into a reflective surface, and the periphery of the cover 10 is removably engaged with the hole 9 for mounting the reflector 1. A locking pawl 12 having a hook portion 11 at its tip is provided protrudingly, and by locking this locking pawl 12 in the hole 9, the cover 10 is attached.
is attached to the reflector plate 1, and this cover 10 is positioned between the plurality of lamps 8 attached to the lamp socket 6 and between the lamp sockets 6, and this cover 10 is formed in a flat shape that does not protrude from the lamp socket 6. has been done.

Furthermore, an insertion hole 14 for an electric wire 13 connected to the ballast 2 is formed near the end of the reflector 1 to which the ballast 2 is attached.

Note that both ends of the cover 10 are formed into inclined surfaces as shown in FIGS. 1 and 2, or formed into arcuate curved surfaces as shown in FIG. 3, or formed into an appropriate shape such as a vertical surface. You can also.

Next, the operation of this embodiment will be explained.

A ballast 2 is attached to a flat reflector 1 in a space between a plurality of lamps arranged in parallel facing the reflector 1, and the ballast 2 is attached with the surface of the reflector 1 By covering with the cover 10 formed on the reflective surface, the device can be assembled without using the main body of the device such as a chassis, and the entire device can be made flat and thin.

Further, the cover 10 is flat and does not protrude beyond the lamp 8 attached to the lamp socket 6, and since the surface of the cover is formed as a reflective surface, the cover does not cast a shadow. Furthermore, since the ballast 2 is in contact with or close to the reflector 1, heat dissipation is enhanced.

Since the surface of the cover 1 (l) is also formed as a reflective surface, there is no light loss, and furthermore, the ballast 2 and the mounting recess 3 are covered by the cover 10, so that the appearance is not impaired.

Note that the lamp 8 is not limited to a straight tube fluorescent lamp, and can also be applied to, for example, a single-cap type lamp.

〔Effect of the invention〕

According to the present invention, a plurality of lamps are respectively installed in a plurality of lamp sockets attached to the reflecting surface side of a flat reflecting plate and arranged parallel to the reflecting surface, and a plurality of lamps are connected to the lamp sockets. The ballast is located between the plurality of lamps attached to the lamp sockets and between the lamp sockets, and is installed close to the reflector, and covers the surface of the ballast attached to the reflector. A flat cover with a reflective surface and a flat cover that does not protrude beyond the lamp mounted in the lamp socket is removably attached to the reflector, so it is placed parallel to and opposite the flat reflector. By installing a ballast in the space between multiple lamps and covering the ballast with a cover whose surface is a reflective surface, the device can be assembled without using the main body of the device such as a chassis. , the entire device can be made flat and thin, the ballast is covered with a cover without damaging the appearance, and the surface of the cover covering the ballast is formed into a reflective surface. Since the cover does not protrude from the lamp, it does not cast a shadow, and there is little light loss.Furthermore, since the cover is mounted close to the ballast reflector, heat dissipation is improved.
