Abstract

PROBLEM TO BE SOLVED: To obtain a luminaire not producing shadows and stripes in a shade as much as possible by fixing a straight tube lamp so as to separate from a fixing tool to a lamp socket installed in the central part of inside both ends of a luminaire body, and installing a fixing frame for shading light of the lamp. SOLUTION: Lamp sockets 14a, 14c, 15a, 15c of straight tube lamps 16a, 16c are directly fixed to a luminaire body 11, and lamp sockets 14b, 15b are fixed so as to separate by a suitable distance from a projection in the center of the luminaire body 11 through fixing frames 31, 32. The fixing frames 31, 32 have large openings in right and left side parts. By installing the large openings in the frames 31, 32, light of a straight tube lamp 16b is radiated to a shade through the openings, brightness of a shade part corresponding to the fixing frames 31, 32 is made almost equal to that of a shade part corresponding to the lamp sockets 14a, 14c, 15a, 15c, and shadows and stripes are eliminated to give comfortable feeling.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminaire, and more particularly to a luminaire capable of uniformly irradiating a lamp with light from a straight tube lamp.

[0002]

2. Description of the Related Art Recently, a luminaire 10 generally formed in a substantially planar shape as shown in FIGS. 3 and 4 is often used.

[0003] The lighting fixture body 11 of the lighting fixture 10 is formed in a substantially planar shape, and a fixture 12,
A plurality of lamp sockets 14 a, 14 b, 14 c, 15 a, and 15 a receiving electric power are provided on both sides thereof.
5b and 15c are provided.

[0004] Although not shown, the mounting fixture 12 is provided with connection terminals and engaging elements, and is formed so as to protrude inside the lighting fixture main body 11, supplies power to the straight tube lamps 16a, 16b and 16c, and also includes a ceiling part and the like. It is designed to be attached to the attachment device.

[0005] A not-shown engaging element of a shade 17 is engaged with the engaging elements 13a and 13b, and straight tube lamps 16a, 16b ...
And the like, and light to be illuminated from now on is applied to the reception area and the like.

[0006] In recent years, the main body 11 of the lighting fixture has become thinner, so that the lamp sockets 14a, 14c, 15a, 1
5c is directly attached to the luminaire main body 11 when there is no protrusion such as the fixture 12 on the lower side, and the straight tube lamp 16
The a and 16c are attached so as not to be far apart from the inside of the lighting fixture body 11.

Further, the lamp sockets 14b, 1
5b is attached to the lighting fixture main body 11 via the mounting frames 18 and 19 when there is a protrusion such as the fixture 12 on the lower side, and the straight tube lamp 16b is attached to the fitting 12 inside the lighting fixture main body 11. It is designed to be installed with some distance from it.

The mounting frame, for example, the support frame 18 is shown in FIG.
As shown in the figure, the bottom plate 21 is formed of a metal frame in which a substantially square case 22 is attached.

Therefore, when the straight tube lamps 17a, 17b,... Are turned on, substantially uniform light is applied to the side surface of the shade 17 where there is no mounting frame 18 or the like. However, the mounting frame 1
On the side surface of the shade 17 where 8 and the like are located, the light is blocked by the mounting frame 18 and the like, and a slightly thin shade or stripe 25 is generated.

[0010] The shadows and stripes 25 not only reduce the accuracy of the light of the luminaire 10, but also impair the comfort of the space such as the reception space.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an illuminating device in which shades, stripes and the like are not generated as much as possible.

[0012]

According to a first aspect of the present invention, there is provided a substantially flat lighting fixture body which is attached to a mounting device by a fixture projecting from an inner central portion, and provided at both ends of an inner surface of the lighting fixture body. A plurality of lamp sockets, and a plurality of straight tube lamps attached to the lamp sockets at both ends of the lighting fixture body, the lamp socket provided at the center of both ends of the inner surface of the lighting fixture body It is an object of the present invention to provide a lighting apparatus characterized in that a straight tube lamp is separated from a fixture and a mounting frame is provided for transmitting the light of the straight tube lamp.

Further, the present invention provides a lighting apparatus characterized in that an opening is opened in the mounting frame according to the second aspect of the present invention.

Further, the present invention provides a lighting apparatus characterized in that the mounting frame according to the third aspect of the present invention is formed of a translucent member.

Further, the present invention provides a lighting apparatus characterized in that the light-transmitting member of the present invention is formed of a synthetic resin.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a lighting device according to an embodiment of the present invention.

Since the lighting fixture 30 of the present invention is basically constructed in substantially the same manner as the conventional lighting fixture 10, the same parts as those of the conventional lighting fixture 10 are denoted by the same reference numerals, and the lighting fixture 30 of the present invention will be described. .

A plurality of lamp sockets 14a, 14b, 14 are provided at both ends of the lighting fixture body 11 of the bright lighting fixture 30.
c, 15a, 15b, 15c are mounted to support the straight tube lamps 16a, 16b, 16c.

These lamp sockets 14a, 14c, 15
The lamp sockets a and 15c are directly mounted on the lighting fixture body 11, and the lamp sockets 14b and 15b are mounted via mounting frames 31 and 32 so as to keep an appropriate distance from the projection of the mounting fixture 12.

Each of the mounting frames 31, 32, for example, the mounting frame 31 is composed of a bottom plate 33 and a case 34 as shown in FIG. I have.

When the large openings 35 are opened in the mounting frames 31, 32, the straight tube lamps 16a, 16b.
The light of the straight tube type lamp 16b is supplied to the shade 1 through the opening 35.
7, the brightness of the shade portions corresponding to the mounting frames 31, 32 is increased by the lamp sockets 14 a, 14 c, 1 on both sides.
The brightness is substantially equal to the brightness of the shade portion corresponding to 5a, 15c.

As a result, the brightness of the shade 17 on both the left and right sides becomes uniform, giving the user a comfortable feeling.

In the above-described embodiment, an opening is formed in the mounting frame, but a transparent synthetic resin may be used for the mounting frame.

In this case, shadows and stripes are further eliminated, and the image quality can be improved.

In addition, a straight tube lamp having a total of three lamps, one at the center and one on both sides, was used, but only one lamp at the center, one at the center and two on both sides. Of course, the present invention can be applied to a device using five devices or a device using a total of seven devices on three sides.

[0026]

According to the present invention, a substantially flat luminaire body attached to a mounting device by a fixture protruding to the inner central portion, and a plurality of lamps provided at both ends of the inner surface of the luminaire body are provided. In a lighting fixture comprising a socket and a plurality of straight tube lamps attached to the lamp sockets at both ends of the lighting fixture body, a straight tube lamp is provided in a lamp socket provided at the center of both ends of the inner surface of the lighting fixture body. Since the mounting frame is provided so as to be separated from the fixture and to transmit the light of the straight tube lamp, no shade, stripes, or the like due to the light of the straight tube lamp is generated in the shade portion of the lighting fixture.
