[0019] The present invention will now be described in more detail with reference to the drawings, showing embodiments and specific examples, but the present invention is not limited to these embodiments and specific examples. In addition, in the following explanation using the drawings, it should be noted that the drawings are schematic and the ratios of the dimensions, etc. may differ from the actual ones, and in order to make it easier to understand, illustrations other than those of parts necessary for the explanation have been appropriately omitted.

[0020] (1) Configuration of the light-emitting device FIG. 1 is a perspective view showing an example of installation of a light emitting device 100 according to this embodiment, and FIG. 2 is a schematic cross-sectional view showing the configuration of the light emitting device 100 according to this embodiment. The configuration and functions of the light emitting device 100 according to this embodiment will be described below with reference to the drawings.

[0021] (Overall configuration of the light emitting device) As shown in FIG. 1, the light emitting device 100 includes a light emitting section 10, a lighting cover 20, and a substrate 30 (not shown). The light-emitting device 100 configured in this manner is installed along a corner C where two surfaces (X and Y in FIG. 1) intersect to form an internal corner, and is used, for example, during the day when the light-emitting unit 10 is turned off so that it blends in with the corner C of the building, and at night when the light-emitting unit 10 emits light to illuminate the area along the corner C. The light-emitting device 100 can also be used as an emergency light by installing it extending in a moving space within a building and having the light-emitting unit 10 emit light in specific directions in sequence.

[0022] 2, the light-emitting unit 10 is configured with an LED tape light 13, which is made up of, for example, a flexible tape-shaped base material 11 and a plurality of light-emitting diodes 12 arranged in a line along the longitudinal direction on the base material 11. The LED tape light 13 is attached to the inner surface 21c of a main body 20A of a lighting cover 20, which will be described later. The main body 20A is integrally formed with a cover 20B by extrusion molding a thermoplastic elastomer resin or a soft resin, and a predetermined region of the cover 20B is formed of a translucent material that transmits light, so that the light-emitting unit 10 is turned on to transmit light.

[0023] The light emitting device 100 is capable of switching the LED tape light 13 on and off, and lights up when a human presence sensor (not shown) detects the presence or absence of a human, and lights up when a human presence sensor detects a human presence when the illuminance detected by an illuminance sensor (not shown) detects the brightness of the surroundings is equal to or lower than a preset reference illuminance. The LED tape light 13 is also capable of displaying guidance to guide people in a specific direction by lighting up the light emitting diodes 12 in sequence in the arrangement direction.

[0024] 2, the lighting cover 20 is a cylindrical cover body that houses the light emitting unit 10 therein. Specifically, the lighting cover 20 is a cover body that is flexible and extends in the longitudinal direction, and includes a main body portion 20A that houses the light emitting unit 10 therein from one end side to the other end side, and a cover portion 20B that has at least a portion of light transmissivity, is made of an elastically deformable material, and covers the main body portion 20A, and is integrally formed into a cylindrical shape by extrusion molding a thermoplastic elastomer resin or a soft resin.

[0025] The lighting cover 20 is flexible and can be installed to fit the corners C of a building, and furthermore, the covering portion 20B is elastically deformable, so that it is not easily damaged even if a person or object comes into contact with the lighting cover 20. As will be described later, the covering portion 20B is integrally formed by extruding a light-transmitting material that transmits light in a predetermined region R1 and a light-shielding material that blocks light in a region R2 other than the predetermined region R1, so that the predetermined region R1 is made light-transmitting. In addition, the lighting cover 20 has a wood grain-like appearance as an example of a decorative layer 20Bc that satisfies the design requirements of its own appearance, and when the light-emitting unit 10 is turned off, it does not completely blend in with the installation location, but its presence is made less noticeable compared to when the light-emitting unit 10 is turned on.

[0026] The substrate 30 (not shown) has an electric circuit for controlling the light emission of the light-emitting section 10 formed thereon, and is disposed outside the light-emitting device 100. The substrate 30 may be provided with a power source for supplying power for causing the light-emitting section 10 to emit light, or may receive power from an external source.

[0027] (2) Lighting cover configuration 3 is a schematic cross-sectional view showing the configuration of the lighting cover 20 according to this embodiment. Hereinafter, the lighting cover 20 will be described in more detail with reference to the drawings.

[0028] (Main body) 3, the lighting cover 20 is composed of a main body 20A having a bottom surface 21 along one surface X of two surfaces of the corner portion C to be installed and a side surface 22 along the other surface Y of the two surfaces, and a cover portion 20B covering the main body 20A and formed of an elastically deformable material. The main body 20A and the cover portion 20B are integrally formed by connecting the bottom surface 21 and one end portion 21a, 22a of the side surface 22 of the main body 20A by extrusion molding of a thermoplastic elastomer resin or a soft resin.

[0029] 3, the main body 20A has a bottom surface 21 and a side surface 22 that intersect with each other to form an L-shaped cross section, and a slit 23 is formed in the side surface 22. When the LED tape light 13 is housed in the main body 20A, the slit 23 opens by deforming the elastically deformable cover portion 20B, making it possible to receive the LED tape light 13.

[0030] 3, the slit 23 is composed of a convex portion 23A and a concave portion 23B facing each other, and when the cover portion 20B is not deformed, the convex portion 23A and the concave portion 23B face each other closely. As a result, when the main body portion 20A is pressed from above, the convex portion 23A and the concave portion 23B come into contact so as to mesh with each other, so that the pressing force is easily transmitted to the bottom surface 21 of the main body portion 20A, and the structure increases the pressure when the bottom surface 21 of the main body portion 20A is attached to the surface X with, for example, double-sided tape.

[0031] A lip shape 21b is formed on one end 21a of the bottom surface 21. The lip shape 21b has a tapered tip in a cross-sectional view, and when the bottom surface 21 of the main body 20A is fixed to one surface X of the two surfaces of the corner portion C with double-sided tape or the like, it is elastically pressed against the surface X and plays a role of a so-called seal that suppresses the intrusion of dust and the like into the bottom surface 21 side. The lip shape may also be formed on one end 22a of the side surface 22. By forming the lip shape 22b on the one end 22a of the side surface 22 as well, the lip shape 22b elastically contacts the surface Y to suppress the intrusion of dust and the like into the side surface 22 side, and the inside of the side surface 22 can be made invisible from above.

[0032] 3, the cover portion 20B is formed in a semi-arch shape so as to connect and cover the bottom surface 21 and the side surface 22 of the main body portion 20A. One end 20Ba of the cover portion 20B is connected to one end 21a of the bottom surface 21 of the main body portion 20A, and the other end 20Bb is connected to one end 22a of the side surface 22 of the main body portion 20A, so that the LED tape light 13 housed in the main body portion 20A is not exposed to the outside from the lighting cover 20.

[0033] The cover portion 20B is integrally formed with the main body portion 20A by extrusion molding. In this embodiment, the main body portion 20A and the cover portion 20B are integrally extrusion molded using a thermoplastic elastomer (TPE) or a soft resin, and both are molded using a thermoplastic elastomer (TPE) or a soft resin having a type D durometer hardness of D50 or less as measured in accordance with JIS K7215.

[0034] "Variation 1" The main body 20A and the cover 20B may be integrally extruded using two types of thermoplastic elastomer (TPE) or soft resin with different hardness. In this case, both have a type D durometer hardness of D50 or less as measured in accordance with JIS K7215, and the cover 20B is molded using a thermoplastic elastomer (TPE) or soft resin with a type D durometer hardness 10 or more lower than that of the main body 20A.

[0035] At least the cover portion 20B of the lighting cover 20 is made of a light-transmitting material. The light-transmitting material has a visible light transmittance of 5 to 80%, preferably 30 to 70%, and more preferably 40 to 60%. If the transmittance is 5% or less, the transmittance of the light emitted inside the lighting cover 20 is low and it is difficult to see from the outside, whereas if the transmittance exceeds 80%, the inside of the lighting cover 20 is easily visible and the LED tape light 13 housed inside can be easily seen from the outside.

[0036] Such resin materials include polystyrene elastomer, polystyrene, polyolefin elastomer, polyolefin, ethylene-vinyl acetate copolymer, polyvinyl chloride elastomer, polyvinyl chloride, polyurethane elastomer, polyurethane, polyester elastomer, polyester, polyamide elastomer, polyamide, etc., and resin materials having a D scale hardness of 40 or less as measured by a type D durometer hardness tester can be used. In this embodiment, polyurethane elastomer or soft polyvinyl chloride resin with a D-scale hardness of 40 or less is used. If the D-scale hardness is 40 or less, when a relatively large downward load is applied to the lighting cover 20, particularly the cover portion 20B (for example, when the cover portion 20B is stepped on with a foot or when an object comes into contact with the cover portion 20B), the cover portion 20B can be easily deformed and damage to the cover portion 20B can be suppressed. When the application of the relatively large load to the cover portion 20B is released, the cover portion 20B returns to its original semi-arch shape.

[0037] "Variation 2" FIG. 4 is a schematic cross-sectional view illustrating the configuration of the lighting cover 20 according to the second modification. The cover 20B may be integrally formed by extruding a light-transmitting material that transmits light in a predetermined region R1 and a light-shielding material that blocks light in a region R2 other than the predetermined region R1. Specifically, as shown in Fig. 4(a), by using a light-shielding material in the region R2 and a light-transmitting material in the region R1, the LED tape light 13 can be made difficult to see from the outside and the direction of emitted light can be restricted. For example, as shown in Fig. 4, by appropriately setting the range of the region R2, the direction of emitted light can be set to a desired angle such as 0 to 30 degrees (see Fig. 4(b)) or 0 to 60 degrees (see Fig. 4(c)).

[0038] FIG. 5 is a diagram for explaining an example of installation of the lighting cover 20 having a modification layer 20Bc on the covering portion 20. In FIG. A decorative layer 20Bc that satisfies the design of the appearance of the covering portion 20B is formed on the surface of the covering portion 20B. Specifically, the decorative layer 20Bc has a design, and a wood grain pattern is formed integrally with the surface of the covering portion 20 during extrusion molding. The decorative layer 20Bc may be formed by directly printing the wood grain pattern on the surface of the covering portion 20B, or a decorative sheet on which a wood grain pattern is printed in advance on a transparent sheet may be attached. As a result, as shown in FIG. 5, when the light-emitting unit 10 is turned off, it does not completely blend in with the baseboard or floor surface of the corner portion C, but its presence is less noticeable compared to when the light-emitting unit 10 is turned on.

[0039] (3) Manufacturing method of the lighting cover 20 The lighting cover 20 according to this embodiment is molded by extrusion molding using a thermoplastic elastomer resin that forms the main body portion 20A and the cover portion 20B. In particular, when the cover portion 20B is made of a material softer than the main body portion 20A, the cover portion 20B is molded by two-color extrusion molding using a thermoplastic elastomer resin that forms the main body portion 20A and a thermoplastic elastomer resin that forms the cover portion 20B and has a type D durometer hardness that is 10 or more lower than that of the thermoplastic elastomer resin that forms the main body portion 20A and the main body portion 20A. Furthermore, when the cover portion 20B is integrally molded using a light-transmitting material that transmits light in the specified region R1 and a light-shielding material that blocks light in the region R2 excluding the specified region R2, the type D durometer hardness is 10 or more lower than that of the thermoplastic elastomer resin forming the main body portion 20A and that of the main body portion 20A forming the cover portion 20B, and the cover portion 20B is molded by three-color extrusion molding using the light-transmitting thermoplastic elastomer resin and the light-shielding thermoplastic elastomer resin.

[0040] The method of forming by extrusion is not particularly limited, but as an example, the material can be produced by extrusion molding as follows. First, the thermoplastic elastomer resin forming the main body 20A and the thermoplastic elastomer resin forming the cover 20B containing a predetermined color master batch are heated and kneaded at 180°C to 230°C to melt, and are simultaneously melt-extruded from a metal mold die outlet heated to 180°C to 230°C, and then cooled and solidified. This results in the lighting cover 20 in which one end 21a of the bottom surface 21 of the main body 20A and one end 22a of the side surface 22 are connected and integrated with the cover 20B having a wood grain pattern formed on the surface.

[0041] (3) Installation of light-emitting devices FIG. 6 is a diagram for explaining installation of the lighting cover 20 at the corner portion C, and FIG. 7 is a diagram for explaining accommodation of the LED tape light 13 in the lighting cover 20. As shown in FIG. The lighting cover 20 is cut to the required length and attached with double-sided tape or the like to one surface X of a corner portion C where two surfaces X and Y intersect to form an inside corner portion. The lighting cover 20 according to this embodiment is extrusion molded using a thermoplastic elastomer resin having a type D durometer hardness of D50 or less as measured in accordance with JIS K7215, and therefore is easier to cut with scissors, a cutter, or the like at the construction site and easier to install than a lighting cover made of a hard synthetic resin.

[0042] The lighting cover 20 cut to the required length has its bottom surface 21 fixed to one surface X of the corner C with adhesive AD such as double-sided tape. As shown in Fig. 6, a slit 23 consisting of a convex portion 23 and a concave portion 23 facing each other is formed in the side surface 22 of the main body portion 20A, and the convex portion 23A and the concave portion 23B face each other closely when the cover portion 20B is not deformed. As a result, by pressing the main body portion 20A from above (see arrow F in the figure), the convex portion 23A and the concave portion 23B come into contact so as to mesh with each other, and the pressing force is transmitted to the bottom surface 21 (see arrow R in the figure), and the main body portion 20A can be firmly fixed to the corner C.

[0043] As shown in FIG. 7(a), by pressing the surface of the cover portion 20B of the lighting cover 20 fixed to the corner portion C from above (indicated by an arrow in FIG. 7), the cover portion 20B is easily deformed since it is made of an elastically deformable thermoplastic elastomer, and as shown in FIG. 7(b), the slit 23 opens widely, and the LED tape light 13 can be inserted into the main body portion 20A. As shown in FIG. 7(c), the lighting cover 20 that accommodates the LED tape light 13 in the main body portion 20A has the deformed cover portion 20B restored to its original shape, so that the LED tape light 13 is not exposed to the outside from the main body 20A. Here, the LED tape light 13 may be left on the main body portion 20A, but it is preferable to attach it to the inner surface 21c of the bottom surface 21 of the main body portion 20A. Then, the LED tape light 13 is electrically connected to a separately prepared substrate 30.

[0044] As described above, the light emitting device 100 may be installed at the installation site by cutting the lighting cover 20 to the required length and, for example, opening the slits 23 while it is fixed to the corner portion C and housing the LED tape light 13 inside the main body portion 20A. Alternatively, the lighting cover 20 may be installed by first housing the LED tape light 13 in the main body portion 20A of the lighting cover 20 cut to the required length and then fixing it to the corner portion C with an adhesive AD such as double-sided tape.

[0045] (4) Effects of the lighting cover 20 and the light emitting device 100 The main body 20A and cover 20B of the lighting cover 20 are integrally extrusion molded using a thermoplastic elastomer (TPE) or soft resin with a type D durometer hardness of D50 or less as measured in accordance with JIS K7215, and are flexible and elastically deformable, allowing them to be installed along the corner C of a building. In particular, when the cover 20B is molded using a thermoplastic elastomer (TPE) or soft resin with a type D durometer hardness 10 or more lower than that of the main body 20A, the cover 20B is easily deformed and unlikely to break when a relatively large downward load is applied to the cover 20B. The cover 20B is integrally formed by extruding a light-transmitting material that transmits light in the specified region R1 and a light-shielding material that blocks light in the region R2 excluding the specified region R1. This makes it difficult to see the LED tape light 13 from the outside, and when it is emitting light, it is possible to limit the direction of the emitted light and emit light at a targeted angle. The surface of the cover part 20B has a design, and is formed with a wood grain pattern. This enhances the design, and when the light-emitting part 10 is turned off, it does not completely blend in with the installation location, but its presence is less noticeable than when the light-emitting part 10 is turned on. The light-emitting device 100 turns on when a human presence is detected by a human presence sensor that detects the presence or absence of a human, and also turns on when a human presence is detected by the human presence sensor in a case where the illuminance detected by an illuminance sensor that detects the brightness of the surroundings is equal to or lower than a preset reference illuminance. The light-emitting device 100 is installed in an extended manner in a moving space within a building, and the light-emitting unit 10 sequentially emits light in specific directions, thereby enabling guidance display.

[0046] Although the embodiment of the present invention has been described above in detail, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims. In particular, the multiple modifications described in the present embodiment can be arbitrarily combined as necessary. (a) The lighting cover 20 comprises a main body 20A which is flexible and extends in the longitudinal direction, housing an illuminant inside from one end side to the other end side, and a cover portion 20B which is at least partially translucent, is formed from a material which is softer and more elastically deformable than the main body 20A, and covers the main body 20A, and the cover portion 20B may be integrally molded from a light-shielding material which blocks light in a region R2 excluding a specified region R1 having a visible light transmittance of 5% or more and 80% or less. (b) The light emitting device 100 comprises a light emitting body consisting of a plurality of light emitting elements, a main body portion 20A which is flexible and extends in the longitudinal direction and houses the light emitting body therein from one end side to the other end side, and a cover portion 20B which is at least partially translucent and is formed from a material which is softer and more elastically deformable than the main body portion 20A and covers the main body portion 20A, and the cover portion 20B may be integrally molded from a light-shielding material which blocks light in a region R2 except for a predetermined region R1 having a visible light transmittance of 5% or more and 80% or less.
