Description

  The present invention relates to a light irradiation apparatus capable of irradiating light from a light source provided therein in a plurality of directions.

  An indicator lamp which is a light irradiation device that displays the state of an apparatus or the like by irradiating light from a light source provided inside to the outside may be emitted in a plurality of directions. For example, an indicator lamp that displays an abnormality of a device installed in a factory needs to be visible by all workers present in the factory. In addition, an indicator lamp such as a ceiling-suspended guide lamp that displays a destination in the passage should be visible from both sides of the passage in the passage direction.

  Therefore, conventional indicator lights used for equipment in factories are those that are attached to the top surface of the equipment, those that are attached to each of a plurality of side surfaces of the equipment, those that are attached to the corners of the equipment via support brackets, Some devices were cut out at the corners of the device and placed inside.

In addition, the conventional ceiling-suspended indicator lamp has a light source arranged in a housing suspended from the ceiling and has a translucent display panel on two surfaces of the housing facing in the passing direction. There is one in which a light source and a translucent display panel are arranged on each of two surfaces of the suspended support body facing each other in the passing direction (see, for example, Patent Document 1).

  However, in the conventional indicator lamp which is attached to the top surface of the device, the visibility from the vicinity of the device is poor when the device becomes large. In the case of being attached to each of the plurality of side surfaces of the device, the attachment work is complicated and the relationship between the plurality of display contents becomes unclear. In the case of being attached to the corner portion of the device via the support metal fitting, it protrudes from the corner portion of the device, so that it is not only easily damaged, but there is a risk of injury to the operator. In the case where the device is arranged inside by cutting out the corners of the device, it is necessary to provide a space inside the device, which is a heavy burden when designing the device.

  In addition, the conventional ceiling-suspended indicator lamp that displays the destination in the passage is difficult to configure in a small and lightweight manner, and the installation work on the ceiling surface becomes complicated.

  An object of the present invention is to provide a light irradiation apparatus that can easily irradiate light in any of a plurality of directions, can be easily mounted and adjusted, and can be configured to be small and light.

As a means for solving the above-described problems, the present invention includes a transparent body that constitutes at least a part of the outer surface, and a light source is disposed inside the transparent body, and the light from the light source is emitted. A plurality of display members that irradiate in a predetermined direction via the translucent body;
At least one connecting member that is movable between the first end of one of the display members and the second end of the other of the display members and connects the two adjacent display members;
Is provided.

  In this configuration, at least two display members that each irradiate light of a light source in a predetermined direction via a translucent body are connected to each other via a connecting member so as to be movable. Accordingly, by moving one of the at least two display members relative to the other, the light irradiation direction by each of the two display members is directed to an arbitrary direction.

  According to this invention, one of at least two display members can be moved with respect to the other via the connecting member, and the irradiation direction of light by each of the two display members can be easily set in an arbitrary direction. Can do. Thereby, light can be easily irradiated in a plurality of arbitrary directions, attachment work and adjustment work are easy, and the apparatus can be configured to be small and light.

  Hereinafter, an indicator lamp device will be described as an example of a light irradiation device according to an embodiment of the present invention. FIG. 1 is a front view of an indicator lamp device 1 which is an example of a light irradiation device according to the first embodiment of the present invention. The indicator lamp device 1 includes display members 11 and 12, connecting members 21 and 22, and attachment members 31 and 32. In the indicator lamp device 1, two display members 11 and 12 are connected to each other by two upper and lower connecting members 21 and 22 so as to be movable. The display member 11 has a rectangular thin plate shape, houses a light source therein, and is provided with a panel-shaped translucent body 113 detachably on the front surface.

  As shown in FIG. 2A, the display member 11 is disposed in a rectangular thin casing with an open front surface, a substrate 118 on which a plurality of LEDs are mounted on the front surface side, and a front surface side of the substrate 118. The diffuser plate 119 is accommodated, and a translucent body 113 is detachably provided on the front surface of the thin casing. The substrate 118 and the diffusing plate 119 constitute a light source of the present invention, and the light of the LED on the substrate 118 is diffused by the diffusing plate 119 and irradiated to the entire surface of the translucent body 113 with substantially uniform illuminance.

  Note that as shown in FIG. 2B, instead of the substrate 118 and the diffusion plate 119, a substrate 128 and a light guide plate 129 may be provided as light sources. A plurality of LEDs facing the end surface of the light guide plate 129 are mounted on the substrate 128. The light guide plate 129 distributes light incident from the end face to the front side with a substantially uniform illuminance over the entire surface.

  The display member 11 emits surface light at the translucent body 113. Arbitrary characters, figures, symbols, etc. can be written on the front surface of the translucent body 113, and the translucent body 113 is colored by selectively driving the LEDs mounted on the substrates 118 and 128. Color light, written characters, and the like can be selectively displayed.

  In addition, an LED that emits blue wavelength light as the first wavelength light is mounted on the substrates 118 and 128, and the second wavelength light having a wavelength longer than that of the first wavelength light is received by the first wavelength light incident from the back surface. The translucent body 113 can also be configured by a fluorescent plate that emits light and exits to the front side, and a filter that transmits only the second wavelength light. Details of the fluorescent plate and the filter are described in Japanese Patent No. 3165378.

  Accordingly, if a plurality of types of translucent bodies 113 that emit light having different wavelengths as the second wavelength light are prepared, the translucent body 113 to be mounted on the front surface of the display member 11 is replaced with another type of translucent body. The color of the display light of the display member 11 can be easily changed without changing the light source simply by replacing with 113.

Concave portions 114, 115, 116, and 117 are formed at the upper and lower ends of each of the first side 111 and the second side 112 of the display member 11. The display member 12 has the same configuration as the display member 11, and includes a panel-like light-transmitting body 123 detachably on the front surface, and upper and lower ends of each of the first side edge 121 and the second side edge 122. In addition, recesses 124, 125, 126, and 127 are formed. The display member 12 is juxtaposed with the display member 11 such that the second side 122 is close to the first side 111 of the display member 11. Accordingly, the recesses 114 and 115 of the display member 11 and the recesses 126 and 127 of the display member 12 are adjacent to each other.

  The connecting member 21 is disposed in the recessed portion 114 of the display member 11 and the recessed portion 126 of the display member 12, and the connecting member 22 is disposed in the recessed portion 115 of the display member 12 and the recessed portion 127 of the display member 12. As shown in FIG. 3, the recess 114 of the display member 11 is provided with a conductor connector 1141 having a cylindrical shape parallel to the side 111.

Similarly to the display member 11, the display member 12 is provided with connectors 1261 in the recesses 124 to 127.

  The connecting member 21 includes a conductor plug 211 inside a main body formed of an insulator. Both end portions of the plug 211 are exposed in parallel to each other downward from the bottom surface of the connecting member 21. The cross section of the plug 211 has a circular shape with an outer diameter substantially equal to the inner diameter of the connectors 1141 and 1261. A portion of the plug 211 exposed from the bottom surface of the connecting member 21 is fitted into the connectors 1141 and 1261.

  Grooves 212 and 213 are annularly formed in the middle portion of the plug 211 exposed from the bottom surface of the connecting member 21, and the stepped portion 1143 is annularly formed on the inner peripheral surface of the connectors 1141 and 1261 in the middle portion in the axial direction. Is formed. By fitting the stepped portion 1143 into the groove portion 212, the removal of the plug 211 from the connector 1141 is restricted in the recessed portion 114. In the recess 126 as well, the removal of the plug 211 from the connector 1141 is restricted in the same manner as the recess 114.

  In the concave portion 114 and the concave portion 126, the both ends of the plug 211 are fitted into the connectors 1141 and 1261, so that the substrate 118 accommodated in the display member 11 and the substrate 118 accommodated in the display member 12 are connected. The connectors 1141 and 1261 and the plug 211 are electrically connected.

  The connecting member 22 is configured in the same manner as the connecting member 21, and connects the display member 11 and the display member 12 in the recessed portion 115 and the recessed portion 127 in the same manner as the connecting member 21. The display member 11 is rotatably supported by the connection members 21 and 22 with the side 111 as a rotation axis, and the display member 12 is rotatably supported by the connection members 21 and 22 with the side 122 as a rotation axis. Therefore, the angle formed by the display member 11 and the display member 12 can be arbitrarily set.

  As shown in FIG. 1, the attachment members 31 and 32 are attached to the second side 112 of the display member 11 and the first side 121 of the display member 12, respectively. The upper and lower ends of the attachment member 31 extend to the display member 11 side. A plug of a conductor (not shown) is exposed from a portion extending toward the display member 11 at the upper and lower ends of the attachment member 31 and is fitted into a connector (not shown) provided in each of the recesses 116 and 117. For this reason, the attachment member 31 is configured to be extendable in the vertical direction, or at least divided into two.

  The attachment member 32 is configured in substantially the same manner as the attachment member 31. Plugs (not shown) exposed from the portions extending to the display member 12 at the upper and lower ends of the attachment member 32 are fitted into connectors (not shown) provided in the recesses 124 and 125 of the display member 12. Attachment holes 33, 34, 35, and 36 are formed at the upper and lower ends of the attachment members 31 and 32, respectively.

  The plugs exposed from the upper and lower ends of the attachment member 31 are not electrically connected to each other inside the attachment member 31, and the end portions are exposed on the back surface of the attachment member 31. On the other hand, each of the plugs exposed from the upper and lower ends of the attachment member 32 is electrically connected inside the attachment member 32. As a result, the display members 11, 12, the connecting members 21, 22 and the attachment members 31, 32 constitute a circuit for supplying power to the LEDs mounted on the substrate 118 as indicated by broken lines in FIG.

  With the above configuration, for example, as shown in FIG. 4A, the angle formed by the display member 11 and the display member 12 is 90 degrees, and each of the display members 11 and 12 forms the corner of the device. In parallel with each other. At this time, the display members 11 and 12 can be fixed to the device by passing the mounting screws through the mounting holes 33, 34, 35 and 36 of the mounting members 31 and 32 and screwing them into the screw holes on the side surface of the device. it can.

Also in this case, the display members 11 and 12 are fixed to the ceiling by passing the mounting screws through the mounting holes 33, 34, 35 and 36 of the mounting members 31 and 32 and screwing them into the screw holes on the side surface of the ceiling surface. can do. In addition, the power supply hole or connector for the LEDs of the display members 11 and 12 need only be provided at one location facing the end of the plug exposed on the back surface of the mounting member 32 on the ceiling surface.

  In addition, in the connection members 21 and 22 and the attachment members 31 and 32, a packing 213 (see FIG. 5) made of an insulating elastic body having a ring shape is externally fitted to an intermediate portion such as the plug 211 exposed from the bottom surface. Accordingly, the waterproofness of the display members 11 and 12 can be secured while maintaining the water tightness of the connectors 1141 and 1261.

  As described above, an LED that emits blue first wavelength light is mounted on the substrates 118 and 128, and second wavelength light having a wavelength longer than that of the first wavelength light is received by the first wavelength light incident from the back surface. When the translucent body 113 is configured by a fluorescent plate that emits light and exits to the front side, and a filter that transmits only the second wavelength light, the translucent body is disposed even after the display members 11 and 12 are arranged at predetermined positions. Only by exchanging 113 and 123, without attaching / detaching the display members 11 and 12 and changing the internal circuit, and without impairing the waterproof function of the display members 11 and 12, the display members 11 and 12 are replaced. The display color of can be easily changed.

Also in this case, by arranging the connecting members 21 and 22 between the respective display members, the angle formed by the respective display members can be set to various angles according to the shape of the mounting position of the light irradiation device. The light irradiation device can be attached to the mounting location.

  Furthermore, as shown in FIG. 6, a plurality of light irradiation devices 3 each having three or more display members arranged in parallel can be stacked in the vertical direction. In this case, an LED that emits blue light as the first wavelength light is used as the light source of each display member, and the transparent body is made transparent. The outer periphery of each light irradiation device 3 is covered with a cylindrical cover 6 made of a fluorescent plate that emits light having a long wavelength and emits the second wavelength light to the front side, and a filter that transmits only the second wavelength light. With this configuration, the arrangement of display colors in the vertical direction can be easily changed simply by changing the combination of the covers 6.

  Moreover, although the indicator lamp apparatus 1 which concerns on said embodiment is an example which formed the display members 11 and 12 in the rectangle, the light irradiation apparatus of this invention is not restricted to this, A display member is triangular, circular, etc. It can be of any shape. In particular, as shown in FIG. 7A, three display members 41, 42, 43 having a regular triangular thin plate shape are provided, and the display members 42, 42, 43 are connected to the display member 41 via connecting members 51, 52.
