Is provided. That is, the light emitting unit 23 is provided so that the emission direction is directed in a direction inclined toward the irradiation target surface 2 along which the contact surface 11 is aligned.
In the present embodiment, the light emitting portion 23 is provided so as to be emitted from the other end portion in the width direction of the inclined surface portion 15. The illuminating device 1 provided with such a light emitting unit 23 is configured to irradiate the irradiation target surface 2 by being emitted substantially uniformly in a line shape from the inclined surface portion 15 of the base unit 10 toward the irradiation target surface 2. Yes.
An example of a specific configuration of the light emitting device 20 will be described later.

The length dimension of the base portion 10 may be set as appropriate from the viewpoints of handleability, workability, and the like. For example, the lighting device 1 is installed in a peripheral shape or a baseboard shape as described later. In the case of a structure, the length may be approximately the same as that of a general construction material such as a peripheral edge or a baseboard. For example, the length of the base unit 10 may be about 1000 mm to 3000 mm.

In addition, you may make it grasp | ascertain this surface cover 29 as a light emission part of the illuminating device 1. FIG.
The surface cover 29 has a thin plate shape and is provided over substantially the entire length of the base portion 10 in the longitudinal direction.
The surface cover 29 is disposed so that one surface in the thickness direction is in contact with or close to the opening side surface of the housing recess 16 of the case 27. Further, the surface cover 29 has the other surface in the thickness direction substantially in the same plane as the inclined surface portion 15 of the base portion 10 (more specifically, the inclined surface portion 15 where the rib 15a is not provided). Arranged.

By providing such a surface cover 29, a plurality of light emitting devices can be provided even when the plurality of light emitting devices 20 are provided adjacent to each other in series along the longitudinal direction of the base portion 10 as described above. The non-light emitting area between the 20 rod-shaped light guides 23 can be relaxed. In other words, since the light emitted from the exit surface 26 of each rod-shaped light guide 23 is incident on the surface cover 29 and diffused, almost the entire surface cover 29 emits light, making the non-light emitting region inconspicuous. it can.
In addition, by providing the surface cover 29 separately as described above, the illumination device 1 with different irradiation patterns can be easily realized, and versatility can be improved. That is, by forming a plurality of different surface covers 29 on which various light distribution patterns are formed, parts other than the surface cover 29 can be used as a common member, and versatility can be improved.

  In the present embodiment, as shown in FIG. 1, an example is shown in which a light distribution pattern for distributing light toward the irradiation target surface 2 side on the surface cover 29 is formed on the surface cover 29. In the illustrated example, a light distribution pattern is formed such that light passing through the surface cover 29 is directed to the irradiation target surface 2 side with respect to the emission direction from the emission surface 26 of the rod-shaped light guide 23 (the optical axis of the emitted light). Is shown. By providing the surface cover 29 having such a light distribution pattern, it is possible to further suppress the light emitted from the lighting device 1 from directly entering the eye, and to attach the irradiation target surface 2. It is possible to more effectively irradiate the vicinity of the target surface 3 (the wall side in FIG. 1).

In addition, as an attachment aspect to the base part 10 of this surface cover 29, it is good also as an aspect attached with adhesive materials, such as an adhesive agent and an adhesive tape. Alternatively, engaging portions are provided on both sides of the front cover 29 in the plate width direction, and engaged portions that engage with the engaging portions are provided on both side edges of the opening of the storage recess 16 of the base portion 10. It is good also as an aspect which attaches the surface cover 29 so that it may fit.
Further, the surface cover 29 may be formed of a material having substantially the same translucency as that of the rod-shaped light guide 23, or may be colored by milky white or the like to have translucency. .
Further, the light distribution pattern of the surface cover 29 described above is an example, and other light distribution patterns may be formed. Further, without providing such a light distribution pattern, the light from the rod-shaped light guide 23 is not provided. It is good also as the surface cover 29 which permeate | transmits emitted light without distributing light.

Moreover, it is good also as an aspect which provided the surface cover 29 divided | segmented into plurality instead of the aspect which provided the surface cover 29 over the full length of the base part 10 as mentioned above. In this case, for example, it is possible to easily replace and maintain the substrates 21 and the like of the plurality of light emitting devices 20 provided adjacent to each other in series along the longitudinal direction of the base portion 10 as described above, connect the power cord, and the like. Therefore, a cover that detachably covers a portion where the substrate 21 is disposed may be provided.
In addition, an operation unit for performing ON / OFF, dimming, or the like of the lighting device 1 may be provided at a proper position of the lighting device 1 or may be provided at a proper position of the attachment target surface 3. Also good. Furthermore, a wireless (wireless) operation unit may be provided as the operation unit of the lighting device 1.

The illuminating device 1 according to the present embodiment is configured as described above, so that it can be easily installed, and the irradiation target surface 2 is effective while suppressing the emitted light from directly entering the eye. Can be irradiated.
That is, the illuminating device 1 has a long, substantially strip-like plate shape and includes the base portion 10 having one surface in the thickness direction as a flat mounting surface 13. Can do. Further, in the base part 10, the one side part in the width direction of the other surface in the thickness direction on the surface side is a flat part 14 substantially parallel to the mounting surface 13, and the other side part in the width direction is an inclined surface part 15. Therefore, as will be described later, when it is installed along the corners on the ceiling side or floor side in the building, it has a so-called fringe-like or baseboard-like appearance, such as a bowl-shaped shielding cover, etc. Appearance can be improved compared with the case where it provides.

  Moreover, it is made into the elongate shape extended along the longitudinal direction of the base part 10, and is rod-shaped light guide as a light emission part so that it may radiate | emit from the inclined surface part 15 so that an output direction may be directed to a substantially orthogonal direction with respect to the inclined surface part 15. A body 23 is provided. Therefore, it is possible to effectively irradiate the attachment target surface 2 while suppressing the emitted light from directly entering the eye. That is, by setting the contact surface 11 of the one end surface in the width direction of the base portion 10 along the irradiation target surface 2, the light emitted from the rod-shaped light guide 23 from the inclined surface portion 15 of the other side portion in the width direction can be obtained. The irradiation target surface 2 can be irradiated over a wide range with relatively good directivity. In addition, for example, as described later, when installed in the corner on the ceiling side, the emission direction of the rod-shaped light guide 23 becomes the diagonally upper ceiling side or the diagonally lower wall side, and is installed in the corner on the floor side. In this case, since the emission direction of the rod-shaped light guide 23 is obliquely below the floor, etc., it is possible to prevent the emitted light from the rod-shaped light guide 23 from directly entering the eye.

Moreover, the position of the rod-shaped light guide 23 from the irradiation target surface 2 can be defined by installing the contact surface 11 of one end surface in the width direction of the base portion 10 along the irradiation target surface 2. In other words, a desired irradiation pattern can be realized in a typical manner. For example, when a lighting device is provided so as to be attached to a wall surface, a ceiling surface, or the like, positioning work and design of the lighting device with respect to the irradiation target surface may be troublesome. The position of the rod-shaped light guide 23 can be defined. Further, by changing the width dimension of the one side portion in the width direction (the flat plate-like portion), the position of the rod-shaped light guide 23 along the width direction of the inclined surface portion 15, the inclination angle, etc., the irradiation range, illuminance, etc. It can be easily changed.

  In the present embodiment, the rod-shaped light guide 23 is provided so as to be emitted from the other end in the width direction of the inclined surface portion 15 of the base portion 10. Therefore, for example, the width dimension of the base portion 10 (that is, the lighting device 1 itself) is efficiently reduced as compared with the case where the rod-shaped light guide 23 is provided so as to be emitted from a portion in the width direction of the inclined surface portion 15 or the like. can do.

In the present embodiment, the base 10 is provided with a storage recess 16 for storing the light emitting device 20 so as to open at the inclined surface portion 15, and the wiring storage recess 17 communicating with one side wall of the storage recess 16 is provided. Provided. Therefore, wiring to the light source 22 (substrate 21) of the light emitting device 20 stored in the storage recess 16 can be wired to the wiring storage recess 17. Further, since the wiring storage recess 17 is provided so as to communicate with one side wall of the storage recess 16, for example, the wiring storage recess is provided so as to communicate with the groove bottom side of the storage recess 16, etc. Compared to the case, the thickness dimension of the base portion 10 (that is, the lighting device 1 itself) can be efficiently reduced.
Further, in the present embodiment, the wiring storage recess 17 is provided so as to communicate with the side wall on one side in the width direction (the contact surface 11 side) of the storage recess 16. Therefore, for example, compared with the case where the wiring storage recess 17 is provided so as to communicate with the side wall on the other side in the width direction of the storage recess 16 (the inclined surface 12 side), the base portion 10 (that is, the lighting device 1 itself). The width dimension can be reduced efficiently.

In the present embodiment, a plurality of light emitting devices 20 are provided adjacent to each other along the longitudinal direction of the base portion 10. Accordingly, it is possible to increase the length of the lighting device 1 itself while improving the light emitting property. That is, for example, compared to the case where a single light emitting device 20 having a length corresponding to the length of the base portion 10 is provided, it is possible to suppress insufficient light emission and uneven light emission along the longitudinal direction. .
Further, in the present embodiment, the light emitting device 20 has a configuration in which incident surfaces are provided at both ends in the longitudinal direction of the rod-shaped light guide 23 serving as a light emitting unit, and the light sources 22 and 22 are disposed opposite to each of the incident surfaces. . Therefore, for example, in comparison with the case where the light source 22 is incident only from one longitudinal end of the rod-shaped light guide 23, the light emitting device 20 is insufficient in light emission at the other longitudinal end or along the longitudinal direction. It is possible to suppress non-uniformity of light emission. Further, for example, an aspect in which LEDs or the like as a plurality of light sources are provided at intervals along the longitudinal direction of the base portion 10 on a substantially strip-shaped substrate that is elongated along the longitudinal direction of the base portion 10. Compared to the case, the uniformity of light emission and the directivity along the longitudinal direction of the base portion 10 can be improved efficiently.
