Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a lighting device provided on a wall surface, it has been common for a cover part such as a globe to be attached to the main body part with screws such as set screws. If the cover part and the main body part are integrally molded, when fixing the lighting device to the wall surface, it is necessary to drive a screw or the like into the wall surface through a slight gap between the cover part and the wall surface, which makes the construction very difficult. Therefore, the main body part and the cover part are provided separately, and set screws or the like are used for attaching the cover part.

[0005] However, when installing a lighting device in a narrow space or the like, it has been difficult to screw-fix the cover part to the main body part attached to the wall surface using tools. Therefore, there is a need for a technique for attaching the cover part to the main body part without using a fixing member such as a screw in order to facilitate the attachment and detachment operations of the cover part.

[0006] An object of the present disclosure is to provide a lighting device that can attach a cover portion to a main body portion without using a fixing member.

Means for Solving the Problems

[0007] The present disclosure relates to a lighting device including a long base portion attached to a wall surface, an LED light source attached to the base portion along the longitudinal direction of the base portion, and a long cover portion attached to the base portion. The base portion has an engaged portion, and the cover portion has an engaging portion that engages with the pre-engaged portion.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0010] In the drawings of the present disclosure, four predetermined directions orthogonal to each other are represented by "Fr direction", "Rr direction", "R direction", and "L direction". In the lighting device 1, the "Fr direction" represents the front direction exposed to the space, the "Rr direction" represents the back direction of the lighting device 1 fixed to the wall surface by a screw, the "R direction" represents the right direction when the lighting device 1 is viewed from the front, and the "L direction" represents the left direction when the lighting device 1 is viewed from the front, respectively.

[0011] As shown in FIG. 1, the lighting device 1 of the present embodiment is fixed to and used on the wall surface W. The wall surface W may be outdoors or indoors. Since the front of the lighting device 1 is shielded by the cover portion 4 and the main body caps 5 are provided at the ends in the R direction and the L direction, it is an indirect lighting device in which direct light does not enter the field of view from the front. In FIG. 1, the wall surface W is represented by a two-dot chain line, and the range of the width and height of the wall surface W is omitted.

[0012] As shown in FIGS. 2 and 3, the lighting device 1 includes a base portion 2, an LED light source 3, a cover portion 4, a main body cap 5, and a tapping screw 6. The lighting device 1 is fixed to the wall surface W by fixing the hollow lighting frame 10 formed by the base portion 2 and the cover portion 4 to the wall surface W (not shown) via screws. As shown in FIGS. 4 and 5, the base portion 2 has an upper surface portion 21, side surface portions 22, a lower surface portion 23, a mounting hole 24, a first engaged portion 25, and a second engaged portion 26. The base portion 2 is a substantially C-shaped base member that extends in the longitudinal direction along the wall surface W and opens in the Fr direction. The base portion 2 is a shaped member obtained by extrusion molding a metal such as aluminum, for example.

[0013] The upper face part 21 and the lower face part 23 are upper and lower plate members that are horizontally arranged with the base part 2 fixed to the wall surface. The lower face part 23 protrudes in the Fr direction more than the upper face part 21. The side face part 22 is a plate member that connects the upper face part 21 and the lower face part 23 in the vertical direction and is fixed to the wall surface W. The lower face part 23 has hook pieces 23a and 23b that face each other downward. The tips of the hook pieces 23a and 23b are bent so as to face each other inward. The mounting holes 24 are insertion holes for fixing screws SC provided at equal intervals in the longitudinal direction of the side face part 22. As shown in FIG. 4, the base part 2 is fixed to the wall surface W by fastening the screw SC to the wall surface W through the mounting holes 24.

[0014] As shown in FIGS. 4 and 5, the first engaged part 25 is an engaging part having a substantially right-angled triangular shape provided at the Fr-direction end of the lower face part 23 and having a tapered surface whose upper face becomes narrower toward the tip. The first engaged part 25 protrudes outward more toward the side face part 22 and has a vertical surface 2a at the end where the protrusion is maximum. The second engaged part 26 is an engaging part having a substantially right-angled triangular shape provided at the Fr-direction end of the upper face part 21 and having a tapered surface whose lower face becomes narrower toward the tip. The second engaged part 26 protrudes outward more toward the side face part 22 and has a vertical surface 2b at the end where the protrusion is maximum. The first engaged part 25 and the second engaged part 26 are engaged with the cover part 4 to fix the cover part 4 to the wall surface W.

[0015] The LED light source 3 includes an LED tube 31, a substrate 32, an LED element 33, an LED cap 34, and a luminaire connector 35. The LED light source 3 is a seamless long LED light source extending in the longitudinal direction of the base portion 2 and is a low-voltage type 12V LED light source. As shown in FIG. 4, the LED tube 31 has a cylindrical shape with a hollow portion 311 at the top, and an LED emitter is installed in the hollow portion 311. The LED tube 31 is a deformable silicon tube and has the effect of diffusing the irradiated light to the outside. The LED tube 31 has engaging grooves 31a and 31b that are paired in the longitudinal direction along the surfaces in the Fr direction and the Rr direction. The engaging groove 31a is engaged with the hook piece 23a of the base portion 2, and the engaging groove 31b is engaged with the hook piece 23b, respectively, so that the LED light source 3 is securely fixed to the base portion 2.

[0016] The substrate 32 is installed on the ceiling surface of the hollow portion 311 and is exposed downward. The LED element 33 is continuously arranged on the exposed surface of the substrate 32 facing downward and is a light-emitting source that irradiates light downward from the lighting device 1. The LED cap 34 is a lid member having a substantially cubic shape. The LED tube 31 can be cut at the end in the L direction with a free length, and the cut end can be covered with the LED cap 34. A cable extends from the end in the R direction of the LED light source 3, and a luminaire connector 35 is provided at the tip. The LED light source 3 is lit by connecting the luminaire connector 35 and a power cable (not shown) via a connector.

[0017] As shown in FIGS. 4 and 5, the cover portion 4 includes an upper surface portion 41, a side surface portion 42, a lower surface portion 43, a first engaging portion 44, a second engaging portion 45, an insertion hole 46, and fins 47. The cover portion 4 is engaged with the base portion 2 and extends in the longitudinal direction, and is a substantially L-shaped cover member that shields the inside of the lighting device 1 by the side surface portion 42 covering the Fr direction. The base portion 2 is a shaped material obtained by extrusion molding a metal such as aluminum. The length of the cover portion 4 in the longitudinal direction is formed to be longer than that of the base portion 2 so as to cover the entire base portion 2.

[0018] The upper face part 41 and the side face part 42 are continuously formed in a substantially L shape, and the side face part 42 is arranged to be exposed in the Fr direction. The lower face part 43 is a plate member that protrudes from the side face part 42 in the Rr direction and is provided so as not to interfere with the LED light source 3. The first engaging part 44 is provided at the end of the lower face part 43, and is a substantially right-angled triangular engaged part having a tapered surface whose upper face becomes thinner toward the tip. The first engaging part 44 protrudes more inward toward the side face part 42, and has a vertical surface 4a at the end where the protrusion is maximum. The second engaging part 45 is provided at the Rr-direction end of the upper face part 41, and is a substantially right-angled triangular engaged part having a tapered surface whose lower face becomes thinner toward the tip. The second engaging part 45 protrudes more inward toward the side face part 42 side, and has a vertical surface 4b at the end where the protrusion is maximum.

[0019] As shown in FIG. 4, the first engaging part 44 of the cover part 4 engages with the first engaged part 25 of the base part 2, and the second engaging part 45 of the cover part 4 engages with the second engaged part 26 of the base part 2. The tapered surface of the first engaging part 44 and the tapered surface of the first engaged part 25 that engage with each other, and the tapered surface of the second engaging part 45 and the tapered surface of the second engaged part 26 are formed at the same angle so as to be easily engaged when they come into contact. After the second engaging part 45 and the second engaged part 26 are engaged, the vertical surface 4b of the second engaging part 45 and the vertical surface 2b of the second engaged part 26 come into contact and support each other, so that the cover part 4 can withstand an external impact applied thereto.

[0020] On the other hand, the vertical surface 4a of the first engaging part 44 and the vertical surface 2a of the first engaged part 25 do not come into contact with each other, and there is a slight space between the vertical surfaces. By having this space, when removing the cover part 4 from the base part 2, the side face part 42 of the cover part 4 is rotated around the vertical surface 4b of the second engaging part 45 as the central axis, so that the first engaging part 44 can be smoothly separated from the first engaged part 25, and the cover part 4 can be easily removed.

[0021] With this configuration, the cover portion 4 is fixedly attached to the base portion 2 so as not to fall off, and engages with the base portion 2 at two locations, namely the first engaging portion 44 and the second engaging portion 45. Therefore, even when an external impact is applied, the engaged state between the cover portion 4 and the base portion 2 is maintained, and the cover portion 4 can withstand an external force without separating from the base portion 2. Further, since the first engaging portion 44 and the second engaging portion 45 of the cover portion 4 and the first engaged portion 25 and the second engaged portion 26 of the base portion 2 have the same tapered surfaces respectively, the cover portion 4 can be easily attached to the base portion 2 simply by fitting the engaging portion of the cover portion 4 into the engaged portion of the base portion 2 fixed to the wall surface. Therefore, no tools or large force are required for attaching the cover portion 4.

[0022] Also, when removing the cover portion 4, after releasing the contact state between the vertical surface 4b of the second engaging portion 45 and the vertical surface 2b of the second engaged portion 26, the cover portion 4 can be easily separated from the base portion 2 along the tapered surfaces of the same angle provided on the paired engaging portion and non-engaging portion. In this embodiment, since the cover portion and the base portion are not connected using screws or the like, there is no risk of accidentally dropping the base portion when removing the screw. Further, since no fixing members such as screws are required for connecting the cover portion 4 and the base portion 2, the man-hours for fastening with fixing members and removing the fixing members during construction can be reduced.

[0023] Also, as shown in FIG. 6, the lighting device 1 can also be used as indirect lighting for the staircase S. In FIG. 6, the staircase S is shown by a two-dot chain line. For example, when installing a lighting device in a narrow space such as directly below the tread S1, if an attempt is made to fix the cover portion to the base portion via a fixing member, the working space is limited, making it extremely difficult to insert tools and the construction is difficult. However, in the lighting device 1 of the present disclosure, after fastening the base portion 2 to the riser S2 of the staircase S, the cover portion 4 can be fitted into the base portion 2 without tools, so that the lighting frame 10 can be easily attached to the staircase S.

[0024] As shown in FIGS. 4 and 5, the insertion hole 46 is provided inside the substantially central portion of the upper surface portion 41 and is an insertion hole for a tapping screw formed to protrude downward. As shown in FIG. 5, the insertion hole 46 forms an insertion portion for the tapping screw 6 that fastens the main body cap 5 to the cover portion 4 and extends over the entire longitudinal length of the cover portion 4. The fin 47 is provided at the lower end of the side surface portion 42 and is a shielding material that extends below the LED light source 3. By the fin 47 shielding the irradiation from the LED light source 3 in the Fr direction, the lighting device 1 becomes indirect lighting.

[0025] The main body cap 5 is a resin cap provided at both ends of the cover portion 4. Although a resin cap is used in the present disclosure, it may be formed of any material. The main body cap 5 is a substantially square plate member and has a dish-shaped hole 51 and an anti-rotation piece 52. The main body cap 5 is a pair of end caps that are attached so as to cover both ends of the lighting frame 10.

[0026] As shown in FIG. 1, for the tapping screw 6, a dish screw is used so that when the main body cap 5 is fastened to the cover portion 4, the head of the tapping screw 6 is flush with the main body cap 5. In accordance with the shape of the tapping screw 6, as shown in FIG. 5, the dish-shaped hole 51 is provided at the substantially center of the upper portion of the main body cap 5 and is processed into a dish-shaped hole having a tapered surface whose diameter shrinks from the exposed surface to the back surface. The anti-rotation piece 52 is an elliptical protrusion provided on the back surface of the main body cap 5. A pair of anti-rotation pieces 52 are provided in the Fr direction and the Rr direction so as to sandwich the dish-shaped hole 51 therebetween.

[0027] As shown in FIGS. 3 and 4, the anti-rotation piece 52 protruding inward of the lighting device 1 is provided directly below the upper surface portion 41 of the cover portion 4. Since the main body cap 5 is fastened to the cover portion 4 with a single tapping screw 6, there is a risk that the main body cap 5 may rotate due to some impulse about the insertion hole 46 as the central axis. However, even if the main body cap 5 attempts to rotate, its rotation is suppressed by abutting against the pair of anti-rotation pieces 52. With this configuration, the main body cap 5 can be fastened to the cover portion 4 with a single tapping screw 6, and the rotation of the main body cap 5 can also be suppressed. As a result, the fastening operation of the main body cap 5 with a plurality of screws becomes unnecessary, and more man-hours can be reduced. In FIG. 4, the tapping screw 6 is shown by a two-dot chain line.

[0028] As shown in FIG. 1, the lighting device 1 is provided on a wall surface for use. The lighting device 1 is indirect lighting in which the irradiation of the LED light source 3 in the Fr direction is shielded by the fins 47 of the cover portion 4, and the surrounding area is illuminated by the opened downward irradiation. The length of the lighting device 1 in the longitudinal direction can be freely adjusted, and it can be provided long or short according to the installation location. Hereinafter, as shown in FIG. 6, the case where the lighting device 1 is installed on the staircase S will be described.

[0029] In the case of a staircase such as the staircase S where the tread S1 is widely provided in the Fr direction, the upper surface portion 41 of the cover portion 4 is brought into contact with the lower surface of the tread S1, and the base portion 2 is fastened to the kick plate S2, so that the lighting device 1 can be provided on the staircase S. When the staircase S is viewed from the front, since the direct light of the LED light source 3 is shielded by the cover portion 4, the lighting device 1 is not felt to be dazzling. In addition, since the LED light source 3 is not directly visible from the outside, the design property of the lighting device 1 can be improved. The tread of the tread S1 is brightly illuminated by the light irradiated downward from the lighting device 1, and the feet can be safely illuminated. Furthermore, there is also an effect of improving the design property of the staircase S illuminated by the indirect lighting.

[0030] Also, when the L-direction and R-direction ends of the staircase S are, for example, wall surfaces. In such a case, the main body cap 5 can be omitted and the lighting device 1 can be provided on the staircase S. The main body cap 5 is provided for the purpose of suppressing the light of the LED light source 3 from directly entering the field of view from the longitudinal end of the lighting device 1. Therefore, in a configuration such as the staircase S, when a wall surface or the like is provided at the longitudinal end of the lighting device 1 and the direct light of the LED light source 3 does not reach the field of view, the main body cap 5 may not be provided on the lighting device 1. In that case, the light emitted from the longitudinal end of the lighting device 1 is projected onto the wall surfaces in the L-direction and R-direction, thereby further enhancing the design.

[0031] Next, the construction method of the lighting device 1 will be described in detail with reference to the drawings together with the effects. In FIGS. 7 to 11, the wall surface W is omitted.

[0032] First, as shown in FIG. 7, the LED light source 3 is attached to the base portion 2. The engagement grooves 31a and 31b of the LED light source 3 are attached to the hook pieces 23a and 23b of the base portion 2 so as to be surely engaged. Since the LED tube 31 provided with the engagement grooves 31a and 31b is made of silicon having variability, the LED light source 3 can be easily attached to the base portion 2 with a slight force.

[0033] Next, as shown in FIG. 8, the base portion 2 holding the LED light source 3 is fastened to a wall surface W (not shown) using a screw SC. Since the fastening work can be performed from the Fr direction toward the wall surface W, a sufficient working space can be maintained. With this configuration, the fastening work of the screw SC can be surely performed even in a narrow place while firmly checking the mounting holes 24 provided in the side surface portion 22. Since there is sufficient room to move the bit of the power tool, the fastening work can be efficiently performed.

[0034] Next, as shown in FIG. 9, attach the main body cap 5 to the cover part 4. Insert a tapping screw 6 through the insertion hole 46 of the cover part 4 via the dish hole 51 of the main body cap 5, and fasten the main body cap 5 to the cover part 4. Confirm that the main body cap 5 is firmly held at the end of the cover part 4 without wobbling around the tapping screw 6 as the central axis by the anti-rotation piece 52. Note that the main body cap 5 may be attached to the lighting frame 10 using the tapping screw 6 after the lighting frame 10 is fixed to the wall surface W, or it may be attached at the end of the construction process.

[0035] Next, as shown in FIG. 10, engage the cover part 4 with the main body cap 5 attached thereto with the base part 2 fastened to a wall surface W (not shown). In FIG. 10, the main body cap 5 and the tapping screw 6 are shown by a two-dot chain line.

[0036] Bring the cover part 4 closer to the base part 2, bring the tapered surface of the first engaging part 44 into contact with the tapered surface of the first engaged part 25, and slide the tapered surfaces of both against each other so that the cover part 4 advances in the direction of the wall surface W. Similarly, slide the tapered surfaces of the second engaging part 45 and the second engaged part 26 against each other so that the cover part 4 is securely fitted into the base part 2. As shown in the cross-sectional view of FIG. 4, the cover part 4 can be fitted and fixed to the base part 2 by engaging the two locations of the first engaging part 44 and the second engaging part 45 of the cover part 4 with the two locations of the first engaged part 25 and the second engaged part 26 of the corresponding base part 2, respectively. Since the cover part 4 and the base part 2 are securely engaged at two locations, they can withstand an external impact.

[0037] The tapered surfaces of the second engaging portion 45 and the second engaged portion 26 have the same angle and are tapered surfaces whose angle increases from the Fr direction to the Rr direction. Therefore, the second engaging portion 45 of the cover portion 4 inserted from the Fr direction can engage with the second engaged portion 26 of the base portion 2 without resistance. Due to the effect of the tapered surface whose angle gradually increases, finally, the vertical surface 4b of the cover portion 4 and the vertical surface 2b of the base portion 2 come into contact with each other, and they can reliably support each other. Note that since the first engaging portion 44 and the first engaged portion 25 also have tapered surfaces with the same angle, the description of the working effects is omitted. As shown in FIG. 4, the vertical surface 4a of the first engaging portion 44 and the vertical surface 2a of the first engaged portion 25 do not come into contact with each other and are engaged with a slight gap therebetween.

[0038] By having a gap between the vertical surface 4a and the vertical surface 2a, when removing the cover portion 4 from the base portion 2, the side surface portion 42 of the cover portion 4 is rotated about the vertical surface 4b of the second engaging portion 45 as the central axis, so that the first engaging portion 44 can be smoothly separated from the first engaged portion 25, and the cover portion 4 can be easily removed. Therefore, tools are not required for the operation of attaching the cover portion 4 to the base portion 2 and the operation of removing it. The lighting device 1 of the present disclosure can easily fit the cover portion 4 into the base portion 2 without requiring a large force.

[0039] By the above construction method, as shown in FIG. 11, the lighting device 1 is attached to a wall surface W (not shown). Note that by performing the same procedure in reverse, the lighting device 1 can also be easily removed from the wall surface W. Without using tools as in the procedure of the attachment construction, by sliding the tapered surfaces of the cover portion 4 and the base portion 2 that are engaged with each other while separating them, the cover portion 4 can be smoothly removed from the base portion 2, and the screw SC exposed on the base portion 2 can be easily extracted from the wall surface W.

[0040] According to the installation method of the lighting device 1 described above, the lighting device 1 can be easily attached to the wall surface W in a short time. Also, since no fixing members such as screws are used for connecting the cover part 4 and the base part 2, tools are not required for attaching and detaching the cover part 4 to / from the base part 2. Just by a simple fitting operation, the attachment and detachment processes of the cover part 4 are completed, so there is no worry of accidentally dropping the cover part 4, and the installation work can be carried out safely. Further, as shown in FIG. 6, even when installing the lighting device in a narrow space such as directly below the tread S1 of the staircase S, the cover part 4 can be fitted into the base part 2 without tools, so the lighting frame 10 can be easily attached to the staircase S.

[0041] The present disclosure is not limited to the above-described embodiments and can be appropriately modified.

[0042] For example, although the base part 2 and the cover part 4 of the present embodiment use an extruded material made of a metal such as aluminum, the present disclosure is not limited thereto. For example, when the lighting device 1 is used indoors, the cover part 4 may be made of resin. Also, the surface of the cover part 4 may be covered with a decorative sheet material or subjected to processing such as hairline finish. Depending on the space where the lighting device 1 is installed, various exterior decorations may be performed on the cover part 4 exposed to the space.

[0043] Also, the LED light source 3 of the present disclosure includes a deformable silicon LED tube 31, but the LED light source is not limited thereto. As long as it has sufficient illuminance, an LED bar light combining a reflector and a bar-type LED substrate may be used, or fluorescent lamp-type LED lighting may be arranged.

[0044] In addition, the engaging portions 44 and 45 provided on the cover portion 4 of the present embodiment and the engaged portions 25 and 26 provided on the base portion 2 are shaped like claws that engage with each other. However, the shapes of the engaging portion and the engaged portion of the present disclosure are not limited to this. Any shape may be used as long as the engaging portion and the engaged portion can engage with each other without using tools. For example, a shape such as an engaging portion having a protruding convex portion and an engaged portion having a concave portion corresponding to the convex portion may be used, and the shapes of the engaging portion and the engaged portion of the present disclosure can be freely designed.
