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), as shown in FIG. 5, for example, 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)
