Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus used in a bathroom having a direct lighting area and an indirect lighting area.

[0002]

2. Description of the Related Art Lighting equipment used in bathrooms and the like is usually
Despite the difference in shape, direct lighting type light sources using a single translucent white glove were the mainstream.

[0003]

As a result, the light transmitted through a single translucent glove of milky white color becomes monotonous in illumination light, has little change, and is unattractive. In addition, in order to secure the required illuminance, it is necessary to increase the light transmittance of the milky translucent glove or to increase the size of the entire lighting fixture. However, when the light transmittance is increased, the light source comes directly into the eyes, which may cause dazzling. Further, when the entire lighting equipment is enlarged, there is a disadvantage that the lighting equipment gives a feeling of oppression to the user in a small bathroom.

[0004]

SUMMARY OF THE INVENTION The present invention has been improved and eliminated in view of the above-mentioned problems, and can employ two illumination systems, a direct illumination system and an indirect illumination system. It is an object of the present invention to provide a lighting device which can secure sufficient illuminance even if it is small.

[0005] In order to solve the above-mentioned problems, the invention according to claim 1 is to provide an indirect illumination area made of a transparent or translucent material on one side of a glove, and to provide other areas with an indirect illumination area. A lighting fixture characterized in that the lighting fixture is a direct lighting area made of a material having a lower light transmittance than the material of the indirect lighting area. By adopting the two lighting methods, the direct lighting method and the indirect lighting method, the lighting is no longer monotonous, and a sufficient atmosphere can be produced. In addition, by adopting both types, the required illuminance can be ensured even in the case of a small size, and the lighting fixture does not compress the narrow indoor space.

According to the second aspect of the present invention, the glove is divided into upper and lower covers, the upper cover is colorless and transparent or colorless and translucent, and the lower cover has a lower light transmittance than the upper cover. It is a lighting device characterized by being milky translucent. By making the upper cover of the two divided gloves colorless and transparent or colorless and translucent, it is possible to obtain indirect lighting on the ceiling surface and to create an atmosphere. In addition, the lower cover is milky white and translucent in which light transmittance is suppressed as compared with the upper cover, and the light source is not dazzling.

According to a third aspect of the present invention, there is provided a lighting apparatus according to the second aspect, wherein the upper cover is subjected to graining. If the upper cover is not subjected to graining, a shadow of light is formed at the joint between the upper cover and the lower cover, and this is reflected on a wall or a ceiling, etc., which is annoying, but in the present invention, the graining is performed. As a result, the light transmitted through the upper cover is entirely uniform, soft and dim, so that such a problem does not occur.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the embodiments of the invention shown in the drawings. FIGS. 1 to 3 show a lighting apparatus 1 according to an embodiment of the present invention, wherein FIG. 1A is a longitudinal sectional side view, FIG. 1B is a side view, and FIG. FIG. 3 is a cross-sectional plan view. As shown in the figure, in this embodiment, a glove 2 attached to a wall surface is divided into two upper and lower covers 3 and 4. The upper cover 3 has a semicircular shape in a plan view as shown in FIG.
As seen from the front, the upper surface gradually rises in an arc shape from the ridge lines at the left and right ends, and has a dome shape with the center being the highest. Also, as shown in FIGS. 1 and 2, the upper cover 3 has a straight outline indicating the boundary between the upper surface and the lower surface, and the outer outline on the upper surface is curved when viewed from the side as shown in FIG. It has a wedge shape. Further, the upper cover 3 is made of a synthetic resin such as polycarbonate, and is colorless and transparent or colorless and translucent, and is entirely textured (a surface treatment method by pear-skin processing or formation of a striped pattern). A ridge 5 for engaging with 4 is formed.

On the other hand, the lower cover 4 has a semicircular shape when viewed in a plan view, like the upper cover 4, but has a semi-elliptical shape when viewed from the front as shown in FIG. Further, as shown in FIG. 1, when viewed from the side, it has a circular shape divided into four parts. The lower cover 4 is made of a synthetic resin such as polycarbonate and has a translucent milky white color having a lower light transmittance than that of the upper cover 3, and has a concave portion on the upper end surface for engaging with the ridge 5 of the upper cover 3. A groove 6 is formed. The engagement between the upper cover 3 and the lower cover 4 is such that, after these concave grooves 6 and the ridges 5 are forcibly fitted, the joints are welded to ensure watertightness. Thereby, it can be used as lighting for a room such as a bathroom that handles water. Further, an insertion hole 8 and a guide cylinder 9 for mounting a light bulb 7 as a light source in a horizontal direction are formed on the back side of the lower cover 3. As shown in FIGS. 1A and 3, a male screw portion having the same pitch as the female screw portion of the socket 10 attached to the wall surface is formed on the outer peripheral surface of the guide tube portion 9. As in the case of the lighting equipment of the above, the rotary attachment / detachment by screws is made possible.

In this way, the glove 2 is divided into upper and lower parts,
Since the upper cover 3 is made colorless transparent or colorless translucent and subjected to graining, and the lower cover 4 is made milky white translucent with light transmittance suppressed more than that of the upper cover 3, the upper cover 3 has a light bulb. The light emitted from 7 passes through the upper cover 3 and is irradiated toward the ceiling, and the light reflected on the ceiling surface indirectly illuminates the room. That is, indirect illumination can be obtained by the upper cover 3. The indirect lighting of the upper cover 3 has a function of complementing the direct lighting of the lower cover 4 described below, and can produce an atmosphere. Further, by the graining, the light of the indirect illumination reflected on the ceiling becomes uniform and soft as a whole, and illumination with a soft feeling can be obtained. Furthermore, the graining process has an advantage that a streak-shaped shadow projected on the wall surface by the end face of the joint surface between the upper cover 3 and the lower cover 4 is blurred and cannot be seen.

On the other hand, in the case of the lower cover 4, the light transmitted therethrough directly illuminates the room. That is, direct illumination is obtained by the lower cover 4. However, as described above, the light transmittance of the lower cover 4 is lower than that of the upper cover 3, and the light source is dazzling even if the user looks directly at the light source 7 through the lower cover 4. Not at all. Note that the globe 2 as an indoor lighting fixture is usually mounted on a ceiling or a wall near the ceiling, and is located at a position considerably higher than the user, so the user must look up obliquely from below. The entire lighting fixture 1 cannot be seen, and the user necessarily sees the bulb 7 through the lower cover 4. Therefore, by suppressing the light transmittance of the lower cover 4 to be lower than that of the upper cover 3, it is possible to prevent the light source from being dazzling. This is because the indirect lighting by the upper cover 3
This can be realized because it has a function of complementing the direct illumination of the lower cover 4. Further, indirect lighting by the upper cover 3,
By adopting the two illumination methods of direct illumination by the lower cover 4, it is possible to secure the required illuminance even if the entire globe 2 is reduced in size, and when applied to a narrow bathroom space, These lighting fixtures 1 do not give a feeling of oppression.

Incidentally, the present invention is not limited to the above-described embodiment, and can be appropriately changed. For example, the overall shape and size of the upper and lower covers 3 and 4 can be changed as appropriate, and the place of use may be applied to a washroom other than the bathroom, a place where water is handled or a place where water is not handled. Is possible.

[0013]

As described above, in the present invention,
Since an indirect illumination area made of a transparent or translucent material is provided on one side of the glove, and the other area is a direct illumination area made of a material having a lower light transmittance than the material of the indirect illumination area, The lighting method and the indirect lighting method will be adopted, and the lighting will not be monotonous,
The atmosphere can be produced sufficiently. In addition, by adopting both types, the required illuminance can be ensured even in the case of a small size, and the lighting fixture does not compress the narrow indoor space.

Further, in the present invention, since the upper cover is subjected to graining, the indirect illumination light transmitted through the upper cover becomes uniform and soft as a whole, giving a calm impression. Can be. In the case of a lighting device without graining, a streak-like light shadow is formed by the end faces of both covers at the joint between the upper cover and the lower cover, and this is reflected on walls and ceilings, which is annoying,
In the present invention, since the grain processing is performed, the indirect illumination light is blurred and does not become annoying.
