Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in a lighting fixture that controls light distribution and provides moisture through light.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, in parks, gardens, etc., the light of night lighting light sources has been controlled to create brightness and darkness of the light and the spread of light in a specific direction, thereby giving people brightness and a sense of well-being through the light.

Generally speaking, in addition to lighting a park or garden with a constant brightness, it is also possible to create a special shape for the shape of the lighting equipment or the globe attached to the lighting equipment in order to create the spread of light in a specific direction. It is being said.

However, there is a limit to the ability to create a special shape for a lighting fixture or globe to create a spread of light, and making the lighting fixture or globe a special shape requires a lot of effort in designing and manufacturing.

Furthermore, there is a drawback that glare cannot be reliably eliminated when installed in parks or gardens simply by making lighting equipment or globes have a special shape.

[Purpose of invention]

The present invention has been devised in view of the above-mentioned points, and aims to provide a lighting fixture that can produce illumination with relatively simple improvements and does not generate glare.

[Means for solving problems]

The present invention has the following structure to achieve the above object. That is, on the outer peripheral surface of a flat plate formed in a rectangular shape along the vertical axis around the light source attached to the main body of the lighting equipment, a light distribution control board having a shade body with an inner surface as a reflective surface is attached in both the long and short directions. They are constructed by alternating directions and stacking them at predetermined intervals.

In addition, the outer surface of the hat body is, for example, a white painted surface,
The space between the shade bodies is configured so that the light source cannot be directly seen from the side of the light source. Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 8.

〔Example〕

In FIG. 1, 1 is a lighting equipment main body,
It has a cylindrical shape. 2 is a support plate provided inside the lower part of the lighting equipment body; 3 is a support rod supported upright on the support plate 2 at a predetermined interval; 4 is a socket fixed to the support plate 2; 5 6 is a flat plate supported on the upper end of the support rod 3, 6 is a cover provided on the upper surface of the flat plate 5, and 7 is a translucent cylinder supported between the lighting device body 1 and the flat plate 5. It is made of translucent resin or glass. 8 is socket 4
The light source is a light source attached to a lamp, such as a high-pressure mercury lamp or a high-pressure sodium lamp.

Reference numeral 9 denotes a light distribution control board stacked around the light source along the vertical axis of the light source 8. A light source insertion hole 10 is provided in the center of a rectangular flat plate 11, and a light source insertion hole 10 is provided on the outer periphery of the flat plate 11. As shown in Fig. 3, the cap body 12
are provided integrally. The shade body 12 is made of aluminum, for example, and the inner surface is a reflective surface, and the outer surface is painted, for example, white, and has a low reflectance.

In addition, the shade body 12 is provided with holes in a part, and the support rods 3
A plurality of them are sequentially stacked with a hollow cylinder 13 sandwiched between them.

Further, the inclination angle of the shade body 12 is, for example, 20 degrees as shown in FIG. Light source 8 from the side direction of light source 8
It is constructed so that it cannot be seen directly and glare is not felt.

The light distribution control board 9 may be constructed by stacking and supporting rectangles with all their longitudinal directions aligned, as shown in FIG. do. The structure shown in FIG. 5 provides illumination mainly in two directions as shown in FIG. 7. Further, according to the structure shown in FIG. 6, an approximately circular area is illuminated as shown in FIG. 8.

The installation height of the lighting equipment shall be approximately 1 m above the ground.

[Effect of invention]

In the above structure, when the light distribution control board is arranged as shown in FIG. 5 and the light source is turned on, direct light hits the inner surface of the shade body 12 of the light distribution control body 9, and the shade body 1
Most of the light is effectively secondary reflected on the outer surface of 2,
It can be illuminated with soft light without causing glare. Furthermore, since the light distribution control board 9 is rectangular, it can provide long illumination mainly in two directions as described above, and is effective when installed to provide illumination along a sidewalk in a park or garden.

Furthermore, when the light sources arranged alternately with the longitudinal and short directions of the light distribution control board shifted as shown in FIG. 6 are turned on, the inner surface of the shade body 12 is The light hits directly and is secondarily reflected on the outer surface of the other shade body 12, making it possible to illuminate with soft light without causing glare, and the light distribution illuminates an approximately circular area on the reflected surface. So,
It is best to set up the facility in a park or garden and illuminate the surrounding area.

[Effect of the invention]

As mentioned above, the present invention provides light along the vertical axis of the light source.
Light distribution control plates having a shade body with an inner surface as a reflective surface are stacked alternately on the outer periphery of a rectangular flat plate with the long and short directions shifted, making it easy to use. As mentioned above, this structure has the advantage of being able to illuminate with soft light without producing glare, and also being able to produce light effects.

[Brief explanation of the drawing]

Fig. 1 is a partially cutaway side view of the lighting fixture according to the present invention, Fig. 2 is a bottom view of the light distribution control body in Fig. 1, Fig. 3 is a sectional view taken along line A-A in Fig. 2, and Fig. 4 The figure is a sectional view taken along line B-B in Figure 2, Figures 5 and 6 are plan views showing the arrangement of the light distribution control body, and Figures 7 and 8 are the same as Figures 5 and 6. The light distribution in the horizontal plane when the light distribution control body is arranged as shown is shown. 1...Lighting device body, 8...Light source, 9...Light distribution control body, 12...Shade body.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) Lighting consisting of light distribution control boards stacked at a predetermined interval around the light source along the vertical axis of the light source attached to the main body of the lighting device.
