Description

  The present invention relates to an illumination guide device, and more particularly, to an illumination guide device that can be used as a walking guide by a pedestrian on indoor and outdoor stairs.

  Conventionally, an emergency lighting fixture (for example, Patent Document 1) including a projector installed so as to irradiate the floor surface with a one-way light distribution has been proposed. Since the emergency lighting device of this patent document 1 is irradiated from a point-like projector provided at a position considerably higher than the floor surface, it can irradiate a wide range and can irradiate a work passage.

  In addition, a staircase illumination device (for example, Patent Document 2) that is mounted with an inclination substantially equal to the gradient of the staircase, a light source that irradiates light on the stepboard, and the surface of the treadboard can be used to illuminate the staircase. There has been proposed a step illumination device (for example, Patent Document 3) including an optical member that distributes the light of the light source so that the luminance gradually increases from the kick-up side toward the nose side. The stair illuminating device of this patent document 2 can illuminate the direction opposite to the stair tread and the wall, and can increase the illuminance in the irradiation direction. Moreover, the illumination device for level | step differences of patent document 3 can confirm the stair nosing effectively.

  Furthermore, a light-emitting skirting board has been proposed that includes a wall-side light-emitting portion that illuminates the wall surface and a floor-side light-emitting portion that illuminates the floor surface (for example, Patent Document 4). In the light emission baseboard of this patent document 4, a wall surface and a floor surface can be illuminated. In the guide illumination device, the line-shaped light emitting section needs to be arranged in parallel to the floor in the passage and in parallel to the staircase gradient in the staircase.

In consideration of daytime safety, it is also necessary to install high-contrast lines and Braille blocks for walking guides near the borders with the nose and walls of the stairs and the walls of the walkway floor. Generally implemented. At night, it is necessary to illuminate the installed lines and braille blocks, and it is necessary to recognize the level difference on the stairs. When a high-luminance light-emitting part is in the field of view, in the case of cataracts or the like, the field of view in the vicinity of the light-emitting part may cause halation that is difficult to visually recognize, so it is necessary to avoid it. The conventional illuminations disclosed in Patent Documents 2 to 4 are favorable because there is no concern that they are difficult to visually recognize because there is no luminance point in the appliance as compared with a typical foot lamp.

  However, in the emergency lighting device of Patent Document 1, since it is composed of a point-shaped projector provided at a position considerably higher than the floor surface, the lighting of the staircase has different luminance depending on the distance and can easily be shaded, making it difficult to recognize, Safety is not good. Moreover, since it cannot fully illuminate if it is not high output, it is not economical.

  In the lighting device of Patent Document 2, the illuminance of the tread surface is increased and the tread surface is easy to understand, but there is no light distribution on the wall surface. For this reason, it is difficult to assist walking by illuminating the boundary line between the tread surface of the staircase and the line-shaped mark attached to the nose.

  The lighting equipment for steps of Patent Document 3 is effective as a visual effect, but the attachment of the light-emitting device to the stair nosing is difficult both in terms of strength and construction. difficult.

  In the light emission baseboard of Patent Document 4, since light is distributed in two directions with a common light source, a one-sided light source such as an LED cannot be used effectively. Further, since the staircase cannot be arranged in parallel with the tread surface, it is difficult to assist walking by illuminating a line-shaped mark that is usually provided near the boundary line with the tread surface wall of the staircase. In addition, since the light distribution is divided in two directions, the efficiency is worse than in the case where the wall and the floor are illuminated in one direction. Furthermore, light distribution in the horizontal direction from the floor tends to cause floor undulations and irregularities, and light unevenness tends to occur.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object thereof is to provide a highly safe and economical lighting guide device that can be easily used as a walking guide by pedestrians on indoor and outdoor stairs. And

  In order to solve the above-described problem, an illumination guide device according to the invention described in claim 1 is an illumination guide device including a light emitting unit that is installed on a wall surface of a passage and emits light for illumination. The emission part is provided continuously or continuously on the wall surface along the passage, and is characterized in that it irradiates the lower wall surface and the walking surface with a line.

  According to a second aspect of the present invention, the illumination guide device according to the first aspect of the present invention is characterized in that the light emitting section includes a second light emitting section on a side surface.

  A lighting guide device according to a third aspect of the invention is characterized in that, in the first or second aspect of the invention, the lighting guide device is arranged parallel to the walking surface in a state of being continuous or intermittent at the start and end of the stairs. And

  The illumination guide device according to a fourth aspect of the present invention is characterized in that, in the first to third aspects of the present invention, an indicator lamp is provided near the start and end of the staircase.

  A lighting guide device according to a fifth aspect of the present invention is characterized in that, in the first aspect of the present invention, it is incorporated in a handrail or a baseboard.

  According to the first aspect of the present invention, in the illumination guide device, the line-shaped light emitting portions are arranged in parallel to the floor in the passage and in parallel to the staircase gradient in the staircase. As a result, a complicated apparatus is not particularly installed, which is economical. A line-shaped contrast along the line of the illumination guide device is formed by light distribution from the light emitting portion of the wall surface on which the illumination guide device is installed. This is a uniform long linear illumination that is not mistaken for other illuminations. Thereby, the pedestrian can recognize the existence of the wall as well as the existence and gradient of the stairs. In particular, in the case of amblyopia, the presence of stairs can be recognized sensuously and safety can be improved.

  In addition, by illuminating the lines and braille blocks installed near the boundary of the stair tread surface and the wall, and near the boundary of the passage floor wall, safety can be ensured at night as in the daytime. Furthermore, when the visual field is diffused as in cataract, if a high-luminance point is in the visual field, halation tends to occur and it is difficult to recognize subtle differences such as steps. However, it is possible to improve safety because it is illuminated uniformly in a straight line along the traveling direction and there is no high luminance point in the field of view like a normal footlight.

  According to the second aspect of the present invention, particularly when the light is taken from the ceiling direction, the upper part of the wall surface is brighter and the brightness is higher. The lighting effect can be further enhanced.

  According to the third aspect of the invention, in addition to the effect of the first aspect, the presence of the stairs can be grasped more intuitively. Therefore, since the spatial structure up to a distant place can be intuitively grasped, it is possible to give a psychological relief especially to a low vision person, such as when stairs and passages coexist.

  According to the invention of claim 4, in addition to the effect of claim 1, it is easy to recognize the existence of the start and end of the staircase, and the safety can be further improved.

  According to invention of Claim 5, in addition to the effect of Claim 1, space can be taken widely.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
