Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot light mounted on a wall of a corridor or stairs.

[0002]

2. Description of the Related Art In a conventional foot lamp, as shown in FIG. 8, a light source 6 of, for example, a 5 W Baby-bulb is mounted in a main body 5 of an instrument, and an irradiation opening 7 of the main body 5 is made of milky acrylic. A translucent cover 10 made of a material is attached to the decorative frame 11 and is attached to the instrument body 5 with a structure not shown. As shown in FIGS. 6 and 7, the foot lamp is embedded in the lower part of the wall of a corridor or stairs.

[0003]

As described above, since the conventional foot lamp is used as a simple auxiliary lighting (for example, a 5W Baby electric bulb is used as a light source), as shown in FIG. 8 (A). , Slightly illuminates a specific place. Furthermore, since the translucent cover attached to the irradiation opening of the instrument body uses an acrylic material, the light emitted from the light source of the foot lamp diffuses to the whole and illuminates the whole. .

Therefore, if the light quantity of the light source is increased in order to increase the brightness of the foot lamp, as shown in FIG.
The brightness becomes brighter in proportion to the amount of light from the light source, and the range illuminated by the light from the light source also broadens. Therefore, the direct light g emitted from the light source increases the degree of glare (hereinafter referred to as “glare”). When the glare is felt, the visual acuity deteriorates for 1 to 2 minutes, so that even if the light amount of the light source of the foot lamp is increased, there is a problem that the feet are hard to see.

Furthermore, the present age is the arrival of an aging society, and as people get older, their eyesight and walking ability deteriorate,
It will be difficult to move the rooms, corridors, stairs, etc. that have been used up to now. In particular, for the elderly who have poor eyesight, there is a problem that they may get seriously injured when moving to a dark corridor or stairs.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a bright foot lamp that does not cause glare even when the light amount of a light source is increased.

[0007]

In order to achieve the above object, the foot lamp of the present invention is a foot lamp in which light from a light source is emitted from an irradiation opening of a fixture body to illuminate the foot. Is provided with a light-transmitting cover formed of a light-shielding louver plate material that emits light within a certain range.

In the above structure, a light-transmissive cover using a light-shielding louver plate material having a characteristic of emitting light in a certain range.
The direct light emitted from the foot lamp mainly illuminates the feet and does not enter the human eyes. Therefore, even if the light amount of the light source of the foot lamp is increased in order to brighten the floor surface illuminated by the foot lamp, the direct light emitted from the light source does not enter the eyes, so that no glare is felt. Therefore, glare does not occur. In addition, the only thing that gets into the eye is the indirect light that the direct light reflects on the floor more than once, so the light of the foot lamp is eye-friendly and becomes a more comfortable and natural light.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. The same components as those of the conventional technique will be described with the same numbers.

FIG. 1 is a cross-sectional view showing a foot light according to the present invention. The foot light according to the present invention includes an instrument main body 5, a light source 15 mounted in the instrument main body 5, and irradiation of the instrument main body 5. It comprises a decorative frame 11 to which the translucent cover 20 according to the present invention mounted in the opening 7 is attached. The foot lamp is mounted by being embedded in a mounting hole formed in the mounting surface 25 such as a wall of a corridor or a wall of stairs.

The light-transmitting cover 20 according to the present invention is formed of a light-shielding louver plate material 30 as shown in FIG. 3, and this light-shielding louver plate material 30 has a minute louver in the center thereof. -A film 32 in which a large number of films 31 are incorporated in parallel, and a transparent polycarbonate having a thickness of 0.87 to 1.3 mm.
It has a sandwich structure in which it is sandwiched between the plastic sheets 33, 33 of the bone.

FIGS. 4 and 5 show the rule of the light-shielding louver plate material.
FIG. 4 is a cross-sectional view showing the relationship between the bar angle and the visible angle.
(A) shows a light-shielding louver plate material having a louver angle of 0 ° and a visible angle of 60 °. In FIG. 4B, the louver angle is 0 degree,
2 shows a light-shielding louver plate material having a visible angle of 90 degrees.

Further, FIG. 5A shows a louver angle of 18 degrees,
FIG. 5B shows a light shielding louver plate material having a visible angle of 60 degrees, and FIG. 5B shows a light shielding louver plate material having a louver angle of 18 degrees and a visible angle of 90 degrees. The visible angle is such that the light from the light source is the left end of the upper louver film 31a and the lower louver film 31a.
It is represented by a crossing angle .theta. . From the above relationship, it can be seen that even if the louver angle is the same, the visible angle increases as the length of the louver film 31 decreases.

Reference numerals c-c and d-d shown in FIG. 1 denote the light emitted from the light source 15 emitted from the irradiation opening 7 of the instrument body 5, and c-
c is the light emitted from the upper part of the translucent cover 20, and is the floor surface 2

It is supposed to illuminate 7.

The operation of the above embodiment will be described with reference to FIG.

FIG. 2 shows the irradiation relationship between a person and a foot lamp. Direct light f emitted from the foot lamp mainly illuminates the feet and does not enter the eyes of a person. Therefore, even if the light amount of the light source of the foot lamp is increased in order to make the floor surface illuminated by the foot lamp brighter, the direct light f emitted from the light source does not enter the eyes, so that no glare is felt. Therefore, glare does not occur.

Further, since only the indirect light that the direct light is reflected once or more on the floor or the like enters the eyes, the light of the foot lamp is eye-friendly and becomes more comfortable and natural light.

As explained above, the light from the light source is
By passing a light-transmitting cover made of a light-shielding louver plate material, the light has a certain direction and illuminates a certain area.
Further, in contrast to the conventional structure in which direct light from the light source directly enters the eye (see FIG. 8 (B)), the foot lamp of the present invention has a structure in which light is emitted only within a certain range. A transparent cover can be provided so that direct light does not enter the eyes, and glare can be suppressed regardless of the light amount of the light source. That is, the brightness is increased to obtain a non-glare foot light.

[0019]

As described above in detail, according to the present invention, since the light-transmitting cover formed of the light-shielding louver plate material that emits light in a certain range is provided in the irradiation opening of the instrument body, the glare is reduced. And get a comfortable light environment with sufficient brightness. Further, since the direct light from the light source does not enter the eyes directly, the brightness can be increased without feeling glare even if the light amount is increased. In addition, since indirect light enters your eyes, you get natural light that is gentle on your eyes and more comfortable. Therefore, it is possible to obtain a footlight that glarelessly illuminates only the necessary area with sufficient brightness.
