Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting staircase.

[0002]

2. Description of the Related Art Conventionally, indoor lighting fixtures have been attached to walls and ceilings such as stairs and corridors provided in buildings such as houses. However, it is not possible to illuminate the area around the feet, such as the stairs, brightly to the corners only by the illumination from above with such a lighting fixture. In recent years, many houses have a high ceiling for producing a large room, and the area around the feet of such a house becomes even darker.

[0003] Therefore, on the lower part of the wall of the stairs and corridors,
It has been studied and practiced to bury a small luminaire to illuminate the area around the foot. FIG. 6 shows an example of such a conventional lighting fixture. This figure 6
In (2), the stairs (A) are illuminated by a plurality of small lighting fixtures (C) embedded in the wall (A).

[0004]

However, in the conventional method of arranging a plurality of small luminaires, it is difficult to illuminate the stairs so that the boundaries between the treads of the stairs can be clearly recognized. Therefore, there was a problem that the settlement was not always good. In addition, installation of multiple lighting fixtures on the wall requires complicated work such as drilling of the wall and heat treatment, etc., which must be performed at multiple locations on site, which increases the construction period and burdens construction costs. It gets bigger.

[0005] Furthermore, since electric work such as electrical wiring connection is usually performed by an electrician, and carpenter / interior work such as drilling is performed by a carpenter / interior workman, a plurality of specialized workmen are required. There was also a problem that the construction period was further extended due to schedule adjustments. The invention of this application has been made in view of the above circumstances,
It is an object of the present invention to provide a new lighting staircase which can solve the conventional problems, can be easily constructed in a short period of time, and can improve the visibility of the boundary between treads of each step.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem by providing a staircase provided with a lighting member, wherein a front edge portion of a tread plate is dark when viewed from a descending direction. In addition, the present invention of the present application provides that the light source as the lighting member is installed on the back side of the tread plate in the lighting stairs. Also, it is preferable that a light source as a lighting member is arranged on the back side of the tread plate, and that an adjusting member for adjusting lighting is provided, that the adjusting member is a cover body, that the light source is an LED, and the like. It is an aspect.

[0007]

Embodiments of the present invention will be described below in more detail with reference to the accompanying drawings.

[0008]

FIG. 1 illustrates an illumination staircase according to an embodiment of the present invention. For example, in the lighting staircase of the present invention shown in FIG. 1, a light source (2) as a lighting member is:
The front edge portion (11) of the tread plate (1) is dark when viewed from the direction of descending the stairs, and the upper surface portion (12) other than the front edge portion (11) is brightly illuminated when viewed from the direction of descending the stairs. Have been.

As shown in FIG. 2, the illumination of the tread plate (1) is divided into the front edge portion (11) and the other upper surface portion (12) to provide dark illumination and bright illumination, respectively. As described above, the front edge portion (1
1) and the upper surface portion (1) other than the front edge portion (11) of the bright illumination.
2) can be easily distinguished, and the front edge portion (11) of the tread (1) can be easily and accurately recognized.

Further, by illuminating each step board as described above, the step board which is one step lower than the illuminance of the front edge portion (11) of the step board A as illustrated in FIGS. Since the illuminance of the upper surface portion (12) other than the front edge portion of B is higher, the contrast between the front edge portion (11) of the tread plate A and the upper surface portion (12) other than the front edge portion of the tread plate B is given. The visibility of the boundary between the treads of each step can be improved, the sense of security when going up and down the stairs can be increased, and the safety of the feet can be ensured.

As the light source (2) in the illumination staircase of the present invention for performing such illumination, for example, an LED or the like can be used. Since the LED is small and has high brightness, the installation space can be reduced, and various colors can be emitted. Therefore, the step board is illuminated with a color tone suitable for the interior color tone of a wall around the stairs, a step board, and the like. You can also.

In addition, in front of the light source (2) as an illuminating member, that is, in the irradiation direction of light from the light source (2), FIG.
As shown in the example, the front edge portion (11) of the tread plate (1) is dark when viewed from the direction of descending the stairs, and the other portions (1
A cover body (3) may be provided as an adjustment member for adjusting illumination so that 2) is brightly illuminated. In the cover body (3), for example, as illustrated in FIG. 5, a peripheral portion (31) is formed of a material having low transparency, and a substantially central portion (32) other than the peripheral portion (31) has high transparency. Light transmitted through the peripheral portion (31) having low transparency is formed of a material, and the light passes through the front edge portion (1) of the tread plate (1).
1) is illuminated darkly, and light passing through the substantially transparent central portion (32) illuminates the other upper surface portion (12) of the tread (1) brightly, and the front edge portion (11) of the tread (1). And the other part (12) can make the illumination boundary clearer.

Of course, in addition to the cover member (3), the adjusting member has, for example, a structure in which a louver film having a fine louver structure inside is sandwiched between polycarbonate or acrylic sheets. Alternatively, a film-shaped louver that can limit the emission angle of the incident light may be provided. With such a film-shaped louver, the light emission angle of the light from the light source (2) is limited, and the tread plate ( By adjusting the illumination so as to reduce the amount of light applied to the front edge portion (11) of 1) and increase the amount of light applied to the other portions (12), the front edge portion (11) of the tread plate (1) is adjusted. Visibility can be improved.

Furthermore, the lighting staircase of the present invention is shown in FIG.
As exemplified in the above, a harness connector (4) is connected as wiring for supplying power to the light source (2), and power can be supplied by the harness connector (4). At this time, a hole (51) for passing electric wiring is previously formed in the riser plate (5) of each step, and the harness connector (4) is inserted through the hole for electric wiring (51) in the space behind the stairs. It is preferable to connect the electric wiring to the lighting member of each stage through the intermediary.

Normally, all work of the electric system is performed by an electrician, but as described above, the harness connector (4)
By connecting them, the carpenter / interior construction worker can also make the electric wiring connection. Therefore, construction other than the primary side power supply in the lighting stairs of the present invention,
It can be easily performed only by a carpenter / interior construction worker other than the electrician without the intervention of the electrician, and can be completed in a shorter time.

Further, according to the present invention, the lighting member is provided with a tread (1).
Because it is provided on the back side, it fits in the interior better than conventional small lighting fixtures that are buried afterwards in the lower part of the wall.
Of course, the present invention is not limited to the above-described example, and it goes without saying that various aspects are possible in detail.

[0017]

As described above in detail, according to the present invention, a new lighting staircase is provided which can improve the visibility of the boundary between the treads of each step and ensure the safety of the feet.
