Description

  The present invention relates to a guide lamp for clarifying the presence of an opening in a wall surface.

  A wall surface such as a passage has many openings such as an entrance of another passage branched from a passage, an entrance / exit of an elevator, an entrance / exit of an automatic door or an emergency door. In many cases, guidance indicator lights, guide lights, and the like are installed around the elevator doors and above the automatic doors and emergency doors.

  However, it is difficult for low-sighted pedestrians to read the characters and marks on the guide indicator lights and guide lights, and the guide indicator lights and guide lights are wide both vertically and horizontally in terms of display space. However, there is a problem that it is difficult for the pedestrian to recognize the light from the guide display light and the guide light as the light from other lighting fixtures and to recognize the presence of the opening on the wall surface.

In order to solve the above problem, as shown in FIG. 11, a means of attaching the guide lamp 6 along the periphery of the door 60 can be considered. Patent Document 1 also discloses a lighting fixture provided around a door in the back of the passage.
Japanese Patent Laying-Open No. 2005-342222 (paragraph 0018 and FIG. 2)

  However, as shown in FIG. 11, the conventional guide lamp 6 is attached not along the wall surface 20 of the passage 2 but along the periphery of the door 60 located at a position recessed from the passage 2. There is a problem that it is difficult for the pedestrian 5 to see the light from the guide light 6.

  Further, as shown in FIG. 12, the conventional guide lamp 6 not only emits light forward from the light source 61 but also irradiates the wall surface 20 from the light source 61. The light is not linear but wide. In addition, for the low-sighted pedestrian 5, the wall surface 20 around the conventional guide light 6 is too bright, so that it may appear to cause halation or appear cloudy. As a result, it was difficult for the low-sighted pedestrian 5 to distinguish the light from the guide light 6 from the light from other lighting fixtures.

  From the above, even if the conventional guide light 6 is attached around the door 60, there is a problem that it is still difficult for the low-sighted pedestrian 5 to recognize the presence of the opening.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a guide light that enables a low-sighted pedestrian to visually recognize the presence of an opening.

Thus, it can be easily distinguished from other light sources and the visibility of pedestrians with low vision can be further improved.

(Embodiment 1)
First, the structure of the guide lamp 1 of Embodiment 1 is demonstrated using FIG. As shown in FIG. 1, the guide lamp 1 includes a body 10 having an opening window 100 formed on the front surface, an LED unit 11 that is housed in the body 10 and emits irradiation light toward the opening window 100, an LED A power supply unit 12 that supplies power to the unit 11 and a translucent member 13 that covers the opening window 100 of the container 10 are provided.

  The container 10 is a long and narrow box-shaped object having an opening window 100 formed on the front surface (see FIG. 2), and has a rectangular rear surface portion 101 and the longitudinal direction of the rear surface portion 101 (from the front to the rear in FIG. 1). The rectangular side surface portions 102 and 102 extending forward from the both side edges (left and right side edges) along the back surface, and the back surface portion 101 from the both side edges (upper and lower side edges) along the short side direction of the back surface portion 101. Are integrally provided with rectangular side portions 103 and 103 (see FIG. 2) extending forward.

  The LED unit 11 includes a plurality of LED packages 110 and a mounting substrate 111 on which these LED packages 110 are mounted side by side in one direction (from the front to the back in FIG. 1). Each LED package 110 includes an LED chip 112 and a package body 113 that covers the bottom and side surfaces of the LED chip 112.

  A set of light emitted from each LED chip 112 becomes elongated light, and irradiates forward (in the direction of the translucent member 13). On the other hand, no light is emitted from the left and right direction to the back direction by the package body 113. Moreover, the light from each LED chip 112 is emitted continuously rather than blinking so that the pedestrian 5 with low vision can easily recognize. Furthermore, the light emitted from each LED chip 112 is white or light bulb color in order to eliminate signal and meaning and make it easy to understand. In addition, as long as it is a single color, the color may be green, which is easy for the pedestrian 5 who is weak in color.

  The power supply unit 12 is electrically connected to the LED unit 11 and is housed in the container 10 together with the LED unit 11. In addition, the power supply unit 12 may be provided separately from the container body 10 instead of being housed in the container body 10 in order to reduce the thickness of the container body 10.

  The translucent member 13 is a cover formed in a plate shape, has a refractive index larger than that of air, and is attached so as to cover the opening window 100 in a state where the LED unit 11 and the power supply unit 12 are housed in the container 10. ing.

  Next, the usage method of the guide lamp 1 of this embodiment is demonstrated using FIG. First, as shown in FIG. 3, the guide lamp 1 faces the wall surface 20 in the longitudinal direction at the opening edge 4 of the opening 3 facing the wall surface 20 in the building passage 2 (near the ridge line of the opening 3). It is attached along one side of the opening edge 4 so as to be parallel to one side of the opening edge 4 of the opening 3. In the present embodiment, the guide lights 1 are attached to the left edge, the right edge, and the upper edge of the opening edge 4, respectively. Here, the opening 3 refers to, for example, an entrance of a new passage 21 branched from the passage 2, an elevator entrance / exit, an automatic door or an emergency door. In the guide lamp 1 attached to the opening edge 4, light is radiated from the LED unit 11 (see FIG. 1) toward the translucent member 13 (see FIG. 1). The light emitted to the translucent member 13 passes through the translucent member 13 and irradiates the outside of the guide lamp 1. At this time, the light from the LED chip 112 is prevented from irradiating the wall surface 20 of the passage 2 by the package main body 113 of each LED package 110 shown in FIG. ing. That is, in the present embodiment, the back surface 101 and the side surfaces 102 and 103 of the package main body 113 and the container body 10 serve as the first light distribution control means, and the light from the LED chip 112 is the wall surface on which the guide lamp 1 is attached. 20 is a structure that does not distribute light.

  As described above, when the guide lamp 1 is attached to the opening edge 4, the light from the guide lamp 1 is radiated regardless of the direction of the pedestrian 5 as shown in FIG. , It can be recognized that there is an opening 3 at the position of the visually recognized light. Further, the pedestrian 5 coming from the passage 21 can also determine that the passage 2 is deployed in the direction in which the guide light 1 is present.

  As described above, according to the present embodiment, as shown in FIG. 1, in order to prevent the irradiation light from the LED chip 112 of the LED unit 11 from irradiating the wall surface 20, the irradiation light is emitted from the opening 3 of the wall surface 20. Since it becomes a linear light along the opening edge 4 and the outline of the opening 3 can be clarified, the amblyopic pedestrian 5 (see FIG. 4) in the passage 2 can see the light from other lighting fixtures. The presence of the opening 3 can be visually recognized without misunderstanding.

  In hospitals and the like, a linear marker line is added near the boundary between the floor 2 of the passage 2 and the wall surface 20 to change the contrast between the vicinity of the boundary and other places as a guide for the sighted pedestrian 5. However, by highlighting the opening edge 4 with light so as to intersect the marker line, it becomes easy to recognize as a space.

(Embodiment 2)
As shown in FIG. 5, the guide lamp 1a of the second embodiment includes a fluorescent lamp (for example, a straight tube type) 14 instead of the LED unit 11, and the guide lamp 1 of the first embodiment (see FIG. 1). Is different. Light is emitted from the fluorescent lamp 14 in all directions, but the back surface portion 101 and the side surface portion 102 of the vessel 10 can prevent light from the fluorescent lamp 14 from irradiating the wall surface 20. That is, the back surface portion 101 and the side surface portion 102 of the container body 10 are the first light distribution control means.

  As described above, according to the present embodiment, even when the fluorescent lamp 14 is used, the outline of the opening 3 of the wall surface 20 can be clarified as in the first embodiment. The pedestrian 5 (see FIG. 4) can visually recognize the presence of the opening 3.

(Embodiment 3)
The guide lamp 1b of Embodiment 3 is different from the guide lamp 1 of Embodiment 1 (see FIG. 1) in that the LED unit 11 is directly attached to the wall surface 20, as shown in FIG. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  Similarly to the first embodiment, the LED unit 11 of the present embodiment is also irradiated forward with light from the LED chip 112. That is, no light is radiated from the left and right direction to the back direction by the package body 113.

  As described above, according to the present embodiment, even when the LED unit 11 is directly attached to the wall surface 20, the outline of the opening 3 of the wall surface 20 can be clarified as in the first embodiment. The weakly-sighted pedestrian 5 (see FIG. 4) in the passage 2 can visually recognize the presence of the opening 3.

(Embodiment 4)
Incidentally, as shown in FIG. 4, when the passage 3 has the opening 3, the pedestrian 5 approaches from all directions, so it is better to emit as much light as possible in the direction parallel to the wall surface 20. .

  Therefore, the guide lamp 1 of the fourth embodiment has the same appearance as the guide lamp 1 of the first embodiment shown in FIG. 1, but the translucent member 13 is a milk white diffusion panel. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In the guide lamp 1 of this embodiment, the light from the LED chip 112 is diffused by the milk white diffusion panel and radiated to a wide area outside. Moreover, since the translucent member 13a is a milk white diffusion panel, the translucent member 13a looks like a light source in a pseudo manner to the pedestrian 5.

  As described above, according to the present embodiment, by using the milky white diffusion panel as the translucent member 13, it is possible to irradiate the irradiation light from the LED chip 112 which is the light emitting unit over a wide range, and thus walking with low vision in the passage 2. The person 5 (see FIG. 4) can visually recognize the presence of the opening 3 from a wide range.

(Embodiment 5)
As shown in FIG. 7, the guide lamp 1 c according to the fifth embodiment is filled with a translucent filler 15 so as to cover the LED unit 11 on the front side (translucent member 13 side) inside the vessel body 10. Thus, it is different from the guide lamp 1 (see FIG. 1) of the first embodiment. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The translucent filler 15 is, for example, a silicone resin and has a refractive index larger than that of the translucent member 13. Moreover, the translucent filler 15 has a specific gravity heavier than air.

  Next, the optical path of the irradiation light from the guide lamp 1c of this embodiment is demonstrated using FIG. The light a1 radiated straight forward from the LED chip 112 travels through the translucent filler 15 filled in the body 10 and is emitted from the translucent member 13 to the outside even when entering the translucent member 13. In this case, since the incident angle is small, the light is not refracted greatly and is emitted straight from the translucent member 13 as it is.

  On the other hand, the light a <b> 2 emitted obliquely forward from the LED chip 112 travels through the translucent filler 15 and enters the translucent member 13. At this time, since the refractive index of the translucent filler 15 is larger than the refractive index of the translucent member 13 on the incident surface of the translucent member 13, the emission angle of the light a2 becomes larger than the incident angle. And since the refractive index of the translucent member 13 is larger than the refractive index of air in the output surface of the translucent member 13, the output angle of the light a2 becomes larger than an incident angle. From the above, the spread angle of the light emitted from the opening window 100 (translucent member 13) to the outside as the irradiation light by the light-transmitting filler 15 is the two connecting the LED chip 112 and both edges of the opening window 100. It can be wider than the angle formed by a straight line.

  As described above, according to the present embodiment, the space between the LED unit 11 and the translucent member 13 is filled with the translucent filler 15, so that light from the LED chip 112 that is a light emitting unit can be irradiated in a wide range. Therefore, the low-sighted pedestrian 5 (see FIG. 4) in the passage 2 can visually recognize the presence of the opening 3 from a wide range.

(Embodiment 6)
As shown in FIG. 8, the guide lamp 1 d of the sixth embodiment is different from the guide lamp 1 of the first embodiment (see FIG. 1) in that a prism 16 is provided instead of the translucent member 13. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In the prism 16, the incident surface 160 is a flat surface, while the output surface 161 has a central portion 162 having a flat surface, and a plurality of convex portions 163 are formed on both sides of the central portion 162. Each convex portion 163 includes a surface 164 along a direction orthogonal to the incident surface 160 and an inclined surface 165 that is inclined toward the incident surface 160 toward the end edge.

  Next, the optical path of the irradiation light from the guide lamp 1d of this embodiment is demonstrated using FIG. First, the light b1 emitted straight forward from the LED chip 112 is incident orthogonally to the incident surface 160, so that it does not refract greatly at the incident surface 160, and the output surface 161 is also a flat surface. Even the surface 161 is not largely refracted. Therefore, the light b1 is radiated in a direction orthogonal to the emission surface 161.

  On the other hand, the light b2 radiated obliquely forward from the LED chip 112 enters the prism 16, and in the case of the translucent member 13 (see FIG. 1) on the inclined surface 165 of the emission surface 161 (when the emission surface is a plane). ) It is refracted so that the spread angle is further widened and radiated to the outside. Therefore, the spread angle of the light emitted as the irradiation light from the opening window 100 (prism 16) to the outside by the prism 16 is made wider than the angle formed by the two straight lines connecting the LED chip 112 and both edges of the opening window 100. Can do.

  As described above, according to the present embodiment, by using the prism 16 in place of the translucent member 13, light from the LED chip 112, which is a light emitting unit, can be irradiated over a wide range. The person 5 (see FIG. 4) can visually recognize the presence of the opening 3 from a wide range.

(Embodiment 7)
As shown in FIG. 9, the guide lamp 1e according to the seventh embodiment is provided with a convex translucent member 13a on the front (outside) instead of the translucent member 13. It is different from reference). In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The light emitted diagonally forward from the LED chip 112 is refracted by the convex translucent member 13a as in the sixth embodiment, and the spread angle is widened more than the case of the translucent member 13 (see FIG. 1), and the outside. To be emitted.

  In addition, since the translucent member 13a is provided so as to protrude forward from the opening window 100, the translucent member 13a has a surface perpendicular to the longitudinal direction (from the front to the rear in FIG. 9), as shown in FIG. The area of the translucent member 13a (horizontal expected angle ω1 from the viewpoint of the pedestrian 5) that can be seen from the pedestrian 5 in the passage 2 on the left side of the extension line A1 extending forward from the right surface 130 is a plate-like shape. It becomes larger than the area (horizontal expected angle ω2) when the translucent member 13 (see FIG. 1) is used. As a result, the visibility of the pedestrian 5 can be further enhanced. Similarly, the area of the translucent member 13a that can be seen from the pedestrian in the passage 2 on the right side of the extension line A2 of the left surface 131 of the translucent member 13a is increased, and as a result, the visibility of the pedestrian 5 is further enhanced. be able to.

  As described above, according to the present embodiment, by providing the convex translucent member 13a, it is possible to irradiate light from the LED chip 112 which is a light emitting unit over a wide range, and thus the low-sighted pedestrian 5 in the passage 2 is provided. The presence of the opening 3 can be visually recognized from a wide range (see FIG. 4).

  As a modification of the seventh embodiment, the translucent member 13a may be milky white. If it does in this way, since the light from LED chip 112 diffuses in translucent member 13a, translucent member 13a looks like a light source in a pseudo manner to pedestrian 5. Since the translucent member 13a is provided so as to protrude forward from the opening window 100, the area that can be seen as a light source in a pseudo manner is increased as described above, and the pedestrian 5 can be seen from a distance.

(Embodiment 8)
As shown in FIG. 10, the guide lamp 1f of the eighth embodiment includes the LED unit 11a including a plurality of LED packages 110 that are separated and mounted on the mounting substrate 111. (See FIG. 1). That is, the LED packages 110 are regularly arranged in a straight line on the LED unit 11a. The cross-sectional view from above is the same as the guide lamp 1 (see FIG. 1) of the first embodiment. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As in this embodiment, by providing regularity to the arrangement of the plurality of LED packages 110, the light for causing the pedestrian 5 to grasp the presence of the opening 3 without misidentifying it as another light source. Can be recognized.

  As described above, according to the present embodiment, the front surface of each LED package 110 that is a point light source is bright, and the front surface between two adjacent LED packages 110 and 110 is darker than the front surface of the LED package 110. Since it can be repeated along the direction (one side of the opening edge 4), for example, it can be easily distinguished from other light sources such as an illumination load, and the visibility of the low-sighted pedestrian 5 (see FIG. 4) can be improved. Further improvement can be achieved.

  Further, by arranging the LED packages 110 that are point light sources in a linear shape (in one direction), linear guide light can be formed with a small amount of light.

  It should be noted that by using a semi-milky white diffusion panel or prism as the translucent member 13 and diffusing (refracting) the luminance of the light from the LED unit 11a so as not to be completely dispersed, the luminance is prevented from becoming dazzling for the pedestrian 5. Can be adjusted.

  As a modification of the eighth embodiment, the LED unit 11a of the eighth embodiment may be used for the guide lights 1b to 1e as in the third to seventh embodiments. Even the guide light having such a configuration has the same effects as those of the eighth embodiment.

  In addition, you may use the guide lamps 1 and 1a-1f of Embodiment 1-8 in the state embedded in the wall surface 20 so that a light emission surface might be exposed. When attached in this way, the guide lights 1, 1a to 1f do not protrude from the wall surface 20, so that the pedestrian 5 can be kept out of the way.

  As a modification of the first embodiment, the light emitted from the LED chip 112 toward the side surfaces 102 and 102 of the container 10 is reflected, and the light is emitted to the outside through the opening window 100 (the translucent member 13). Such a reflector may be stored in the container 10. With such a configuration, the light emitted from the LED chip 112 in the direction of the side surfaces 102 and 102 can be radiated to the outside from the opening window 100 (the translucent member 13) as irradiation light, and is also emitted to the outside. The spread angle of the light can be wider than the angle formed by two straight lines connecting the LED chip 112 and both edges of the opening window 100. As a result, light from the LED chip 112 that is a light emitting unit can be irradiated over a wide range, so that a low-sighted pedestrian 5 in the passage 2 can visually recognize the presence of the opening 3 from a wide range.
