Abstract

PROBLEM TO BE SOLVED: To provide an outer illumination type illumination device, in which a fluorescent lamp is adopted as a spot light in place of an incandescent lamp or a mercury lamp, and which is especially suitable for the illumination of a nearby slender advertisement signboard. SOLUTION: As for the illumination device 10, both end parts of a fixture body 12 to be mounted on a linear-type fluorescent lamp 11 is being supported by a pair of support arms 16, 16 to protrude forward from an illuminated body, such as the advertising signboard 31 or the like via an angle adjusting means 15. For the fluorescent lamp 11, because the numerical value of all the light flux is enhanced and the shape is slender, the lamp is suited to illuminate the nearby advertisement signboard, and further a less number of light is needed because diffused light is long.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external lighting device for illuminating advertising billboards, product displays, etc. from the outside.

[0002]

2. Description of the Related Art Conventionally, when an outdoor advertising signboard or the like is illuminated with a spotlight from the outside, as shown in FIG. 15, incandescent lamps are provided at the tips of a plurality of support arms 2 projecting forward of the advertising signboard 1. Alternatively, an external illumination type lighting device is generally used in which the mercury lamp 3 is mounted and the illuminated surface of the advertising signboard 1 is illuminated from the front.

[0003]

However, in the above conventional lighting device, since the shape of the lamp is a round spot,
It is suitable for illuminating distant billboards, but when illuminating nearby objects, the problem is that round spots stand out. In addition, incandescent lamps and mercury lamps are 1
It consumes a large amount of electricity per lamp and has a short service life, which is economically disadvantageous.

The present invention solves the above-mentioned problems of the prior art by adopting a fluorescent lamp as a spotlight in place of an incandescent lamp or a mercury lamp, and particularly an external illumination which is suitable for illuminating a long narrow advertising billboard or the like. The purpose is to provide a device.

[0005]

In order to achieve the above object, in the external lighting device of the present invention, both ends of the fixture main body to which the linear fluorescent lamp is attached are forwardly directed to an illuminated object such as an advertising signboard. It is characterized in that it is supported by a pair of projecting support arms via angle adjusting means.

Since the diameter type fluorescent lamp has a high numerical value of total luminous flux and an elongated shape, it is suitable for illuminating an elongated advertising sign in the vicinity due to the above configuration, and the number of lamps can be small because the diffused light is long.

When a plurality of instrument bodies are linearly arranged in the longitudinal direction, it is preferable that they are arranged so as to be connected to each other substantially on the same straight line via an adjusting rod connected to the angle adjusting means.

The instrument body is formed in a gutter-shaped body having an opening on the irradiation side. When the device body is arranged so as to irradiate the object to be illuminated upward, it is preferable to cover the opening with a transparent cover to prevent rainwater and dust from entering. .

Further, if both ends of the instrument body are supported on the support base through the angle adjusting means so that the angle can be adjusted, and the support base is left on the floor or ceiling of the show window,
It can also be used as lighting for product displays.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an external lighting device 10 according to the present invention, and FIG. 2 shows the same lighting device 10.

And a set screw 19 for fixing 18 to the cylindrical member 17 in an arbitrary phase. The cylindrical member 17 is shown in FIG.
And, as shown in FIG. 5, a flange portion 22 having a fitting hole 20 and a screw hole 21 communicating with the fitting hole 20 provided from the outer peripheral surface toward the center and being continuously provided at one end, As shown in FIG. 3, the screws 23 are screwed and fixed to the side plate 14. As shown in FIGS. 6 and 7, the support member 18 has a fitting portion 2 rotatably fitted in a fitting hole 20 of the cylindrical member 17.
4 and a support arm mounting portion 25 orthogonal to the fitting portion 24, and an annular groove 26 is provided on the outer peripheral surface of the fitting portion 24. In addition, the support arm attachment portion 25 has a fitting portion 2
4 is provided with a mounting screw hole 27 that opens in a direction orthogonal to the center line of the support arm 1.
6 is screwed to the support arm 16 so that the support member 18
Attached to.

Thus, as shown in FIG. 3, the support arm 1
The set screw 24 of the support member 18 attached to the tip of the set 6 is rotatably fitted into the fit hole 20 of the cylindrical member 17 fixed to the side plate 14 of the instrument body 12 and screwed into the screw hole 21. The support member 18 can be fixed to the cylindrical member 17 in an arbitrary phase by engaging the tip end portion 19 of the groove 19 with the annular groove 26 and pressing the annular groove 26. With such a structure, the support angle of the instrument body 12 with respect to the support arms 16 and 16 can be arbitrarily adjusted.

FIG. 2 shows an example of use of the illuminating device 10 having the above-mentioned structure, in which the mounting bracket 3 for both supporting arms 16, 16 is mounted on the wall surface 32 on which the advertising signboard 31 is mounted.
3, 33 are attached to the advertising signboard 31 in a posture in which they project forward from both upper sides. Inserting the base end portions of both support arms 16 and 16 into the mounting brackets 33 and 33, attaching both support arms 16 and 16 so as to project to the upper front of the advertising signboard 31, and supported by both support arms 16 and 16. The advertising sign 31 is illuminated as a spotlight from the upper front by the fluorescent lamp 11 attached to the appliance body 12 described above. By adjusting the support angle of the instrument main body 12 with respect to both the support arms 16 and 16 by operating the set screw 19 as described above, the irradiation angle of the fluorescent lamp 11 with respect to the advertising signboard 31 can be arbitrarily changed. .

The support member 18 'provided on substantially the same axis as that of No. 4 is used. Then, as shown in FIG. 11, by fixing the adjusting rod 30 inserted into the connection port 28 with the set screw 29, as shown in FIG. 8, the plurality of instrument bodies 12 are connected to each other via the adjusting rod 30. And are arranged substantially on the same straight line.

FIG. 12 shows an example in which the illuminating device 10 of the present invention is used to illuminate the advertising signboard 31 by illuminating it as a spotlight from the lower front side of the advertising signboard 31 upward. As shown in FIG. 13, the instrument main body 12 has an opening 35 covered with a transparent cover body 36 made of acrylic resin to prevent rainwater, dust, and the like from entering the instrument main body 12.

FIG. 14 shows an embodiment in which the lighting device 10 of the present invention is used for lighting a product display. Both ends of the instrument body 12 are supported by a support base 37 via angle adjusting means 15, 15 attached to the side plates 14, 14 so that the angle can be adjusted, and the support base 37 is installed on a floor surface or a ceiling such as a show window. Then, it is illuminated as a spotlight by the fluorescent lamp 11 attached to the instrument body 12 from below or above the product.

[0018]

As described above, since the lighting device of the present invention employs the linear fluorescent lamp as the spotlight, it is particularly suitable for spot lighting such as long and narrow advertising signs and product displays. In addition, fluorescent lamps consume less power and have a longer life than incandescent lamps and mercury lamps, and since the diffused light is long, the number of lamps can be small, which is also very economical.
