Best Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings.Each of the embodiments described below shows a specific example of the present invention.Therefore, the numerical values, shapes, materials, components, arrangement positions and connection forms of the components shown in the following embodiments are merely examples and are not intended to limit the present invention.Therefore, among the components in the following embodiments, the components not described in the independent claims indicating the highest concept of the present invention are described as optional components.

[0011] Note that each drawing is a schematic diagram and is not necessarily drawn precisely.Also, in each drawing, the same reference numerals are given to substantially the same configurations, and duplicate explanations are omitted or simplified.Furthermore, in this specification, the terms "upper" and "lower" do not necessarily refer to the upward (vertically upward) and downward (vertically downward) directions in an absolute spatial sense.In this specification, the ceiling side is regarded as the upper side and the floor side is regarded as the lower side.That is, the direction of the ceiling side is the upward direction and the direction of the floor side is the downward direction.

[0012] (Embodiment 1) FIG. 1 is a diagram showing a state when the lighting device 1 according to Embodiment 1 is installed on the wall surface 100.In FIG. 1, the lighting device 1 is shown in a lit state.

[0013] As shown in FIG. 1, the lighting device 1 is a bracket-type lighting device (bracket light) installed on the wall surface such as a room of a building.In the present embodiment, the optical axis of the lighting device 1 is in the vertical direction, and the lighting device 1 irradiates illumination light in the vertical direction.Specifically, the lighting device 1 irradiates illumination light upward and downward.

[0014] Next, the specific configuration of the lighting device 1 according to Embodiment 1 will be described with reference to Figure 1, and with reference to Figures 2 and 3. Figure 2 is a perspective view of the lighting device 1 according to Embodiment 1. Figure 3 is a cross-sectional view of the lighting device 1 according to Embodiment 1.

[0015] As shown in Figures 2 and 3, the lighting device 1 comprises a lighting fixture 2 and lamps 3 mounted on the lighting fixture 2. In this embodiment, two lamps 3 are mounted on the lighting fixture 2. In other words, the lighting device 1 is a bracket light for two lamps. Each lamp 3 is detachably mounted on the lighting fixture 2. In other words, both lamps 3 are replaceable.

[0016] The lighting fixture 2 comprises a base 10, a bracket 20, a shade 30, a first socket 41, a second socket 42, a lamp removal lever 50, a first optional member 61, and a second optional member 62.

[0017] The base 10 is attached to the object on which the lighting device 1 is to be installed. As shown in Figure 1, in this embodiment, the lighting device 1 is installed on a wall surface 100, so the base 10 is attached to the wall surface 100. The base 10 is a mounting member for attaching the lighting device 1 to the wall surface 100.

[0018] The base 10 is attached to the wall surface 100 by screws. Therefore, as shown in Figure 2, the base 10 has two through holes 11 as screw holes into which the screws are inserted.

[0019] Furthermore, the base 10 has an insertion hole 12 through which the electric wire 71 is inserted. The insertion hole 12 is located opposite the center of the shade 30 in the longitudinal direction (vertical direction in this embodiment). The insertion hole 12 is provided between the two through holes 11.

[0020] The electric wire 71 inserted through the insertion hole 12 is a power supply line for supplying power to the lamp 3. The electric wire 71 is connected to an external power source and supplies power from the external power source to the lighting device 1 to make the lamp 3 light up. For example, the lighting device 1 is supplied with commercial AC power (grid power) from an external power source via the electric wire 71. Specifically, one end of the electric wire 71 is connected to the external power source. Also, as shown in Figure 3, the other end of the electric wire 71 is connected to a terminal block 72 inside the base 10. The electric wire 71 that is pulled out from the base 10 to the outside is connected to the external power source by being inserted through a hole formed in the wall surface 100 or routed along the wall surface 100.

[0021] The electric wire 71 is, for example, a power cable and has, for example, at least two or more power supply wires and an outer cover (sheath) that covers the multiple power supply wires. Each of the multiple power supply wires is composed of a core wire such as a copper wire and an insulating film that insulates the core wire. The outer cover is an insulating protective member and is composed of, for example, an insulating resin material such as rubber.

[0022] A bracket 20 is fixed to the base 10. As shown in Figures 2 and 3, the bracket 20 is fixed to the base 10 by screws 81. Specifically, the upper end plate of the bracket 20 and the upper end plate of the base 10 are superimposed, and the upper end plate of the bracket 20 and the upper end plate of the base 10 are fixed together by screws 81.

[0023] As shown in Figure 2, the bracket 20 has a pair of opposing partitions 21. The pair of partitions 21 are erected at the ends of the upper plate of the bracket 20. This allows the screws 81 that are screwed to the upper plate of the bracket 20 to be hidden by the pair of partitions 21. In other words, the screws 81 can be made less conspicuous.

[0024] As shown in Figure 3, the case C is composed of a base 10 and a bracket 20. A terminal block 72 is placed inside this case C. The terminal block 72 is fixed to the bracket 20 by screws 82. The terminal block 72 and the first socket 41 are electrically connected by a pair of lead wires 73. The terminal block 72 and the second socket 42 are also electrically connected by a pair of lead wires 73. The pair of lead wires 73 connecting the terminal block 72 and the first socket 41 may be bundled together with a cable tie or the like and fixed to the first socket 41, etc. Similarly, the pair of lead wires 73 connecting the terminal block 72 and the second socket 42 may also be bundled together with a cable tie or the like and fixed to the second socket 42, etc.

[0025] The base 10 and bracket 20 are made of a metal material such as aluminum or iron, or an insulating resin material. The materials that make up the base 10 and the materials that make up the bracket 20 may be the same or different. In this embodiment, the base 10 is made of a metal plate, and the bracket 20 is made of an insulating resin material.

[0026] The shade 30 is fixed to the bracket 20. As shown in Figure 3, the bracket 20 and the shade 30 are fixed together by screws 83.

[0027] The shade 30 is the fixture body in the lighting device 1 and lighting fixture 2. As shown in Figure 3, the shade 30 is a housing that covers two lamps 3. Therefore, the two lamps 3 are housed in the shade 30. In this embodiment, the shade 30 not only houses the two lamps 3, but also houses the first socket 41 and the second socket 42. In other words, the first socket 41 and the second socket 42 are located inside the shade 30.

[0028] The shade 30 is a long, cylindrical body and has a first opening 31 located at one end in the longitudinal direction of the shade 30 and a second opening 32 located at the other end in the longitudinal direction of the shade 30.

[0029] As shown in Figure 1, when the lighting device 1 is installed on the wall surface 100, the shade 30 extends vertically. That is, the longitudinal direction of the shade 30 is vertical. In this case, the first opening 31 opens upward (towards the ceiling), and the second opening 32 opens downward (towards the floor, towards the ground). That is, the first opening 31 is an opening on the upper side (towards the ceiling), and the second opening 32 is an opening on the lower side (towards the floor, towards the ground).

[0030] As shown in Figures 2 to 4, in this embodiment, the shade 30 is a slender cylindrical body with a constant outer diameter. Figure 4 is a perspective view of the shade 30 in the lighting device 1 according to Embodiment 1. As shown in Figure 4, if the outer diameter of the shade 30 is a and the length of the shade 30 in the longitudinal direction is b, then, as an example, 2 ≤ b / a ≤ 20. The shade 30 may be even more slender, and 3 ≤ b / a may also be the case. In this embodiment, the shade 30 is a long cylindrical member with a = 50 mm and b = 200 mm (b / a = 4).

[0031] As shown in Figures 1 to 3, the shade 30 is an outer cover that constitutes the outer casing of the lighting device 1. The shade 30 may or may not be light-transmitting. In this embodiment, the shade 30 is not light-transmitting and is made of an opaque material. Therefore, the illumination light emitted from the lamp 3 housed in the shade 30 does not exit from the outer peripheral sides of the shade 30, but only from the first opening 31 and the second opening 32 of the shade 30.

[0032] The shade 30 is made of a metal or resin material. In this embodiment, the shade 30 is made of a metal material. Specifically, the shade 30 is made of aluminum. As an example, the shade 30 is formed into a cylindrical shape by extrusion molding using aluminum.

[0033] As shown in Figures 3 and 4, the shade 30 has a slit hole 33 that extends along the longitudinal direction of the shade 30. The slit hole 33 is an elongated hole for sliding the lamp removal lever 50. The slit hole 33 is located on the shade 30 opposite the bracket 20.

[0034] Furthermore, as shown in Figure 3, the shade 30 has an insertion hole 34 through which lead wires 73 connecting the terminal block 72 and the first socket 41 are inserted. Lead wires 73 connecting the terminal block 72 and the second socket 42 are also inserted through the insertion hole 34.

[0035] The first socket 41 and the second socket 42 receive power from the electric wire 71. Specifically, the first socket 41 and the second socket 42 receive AC power from the electric wire 71 via the terminal block 72 and lead wires 73. The first socket 41 and the second socket 42 also have the function of holding the lamp 3 and are electrically and mechanically connected to the lamp 3. The first socket 41 and the second socket 42 supply the AC power received from the electric wire 71 to the lamp 3.

[0036] Each of the first socket 41 and the second socket 42 has, for example, a pair of conductive connection terminals that are electrically and mechanically connected to the lamp 3, and an insulating housing that houses the pair of connection terminals. The pair of connection terminals are connected to each of a pair of lead wires 73 that are connected to the terminal block 72. In other words, AC power is supplied to the pair of connection terminals. For example, the connection terminals are made of a metal material, and the housing is made of an insulating resin material. In this embodiment, the first socket 41 and the second socket 42 have the same structure.

[0037] The first socket 41 and the second socket 42 are supported by a support member 43. Specifically, the first socket 41 and the second socket 42 are fixed to the support member 43 by screws. The support member 43 maintains the predetermined positions of the first socket 41 and the second socket 42 within the shade 30. The first socket 41 and the second socket 42 are positioned symmetrically above and below each other with respect to the midpoint of the longitudinal direction of the shade 30.

[0038] The support member 43 is made of a metal plate. The support member 43 is fixed to the shade 30 by a screw 83. In this embodiment, as described above, the screw 83 also fixes the bracket 20 and the shade 30. In other words, the support member 43, the bracket 20 and the shade 30 are fastened together by the screw 83. Note that the support member 43 is not limited to a plate-like body made of a metal plate, but may also be a block body made of a metal material such as aluminum and a resin material.

[0039] As shown in Figure 3, the shade 30 is provided with a lamp removal lever 50. The lamp removal lever 50 has the function of removing the lamp 3 from the shade 30. Here, the detailed structure of the lamp removal lever 50 will be described using Figures 5 and 6 with reference to Figure 3. Figures 5 and 6 are perspective views of the lamp removal lever 50 in the lighting device 1 according to Embodiment 1.

[0040] As shown in Figures 5 and 6, the lamp removal lever 50 has a sliding portion 51, a projection 52 provided on the sliding portion 51, and a ring portion 53 provided on the projection 52.

[0041] As shown in Figure 3, a portion of the lamp removal lever 50 is positioned between the bracket 20 and the shade 30. Specifically, a sliding portion 51 of the lamp removal lever 50 is positioned between the bracket 20 and the shade 30. The sliding portion 51 slides along the longitudinal direction of the shade 30. As the sliding portion 51 slides, the lamp removal lever 50 moves along the longitudinal direction of the shade 30.

[0042] Furthermore, a knob 51a is provided at the upper end of the slide portion 51 (the end opposite to the projection 52). The knob 51a protrudes from the slide portion 51 toward the wall surface 100. The knob 51a is provided so as to be upright on the slide portion 51. The knob 51a is also provided in a position opposite to the upper end plate of the bracket 20. A gap large enough for a person's finger is provided between the knob 51a and the upper end plate of the bracket 20. This allows the slide portion 51 of the lamp removal lever 50 to be slid by hooking a finger onto the knob 51a and pulling it up.

[0043] In this embodiment, the knob portion 51a is positioned between a pair of partition portions 21 provided on the upper end plate of the bracket 20. This allows the knob portion 51a to be hidden by the pair of partition portions 21. In other words, the knob portion 51a can be made less conspicuous.

[0044] Alternatively, a protrusion or recess may be provided on the bracket 20-side surface of the slide portion 51, and a recess or protrusion may be provided on the bracket 20-side surface of the slide portion 51, so that the protrusion or recess of the slide portion 51 and the recess or protrusion of the bracket 20 are fitted together by light press-fitting. In this case, the fitted state between the protrusion or recess of the slide portion 51 and the recess or protrusion of the bracket 20 can be easily released by sliding the slide portion 51 upward. Also, by sliding the slide portion 51 downward and returning it to its original position, the protrusion or recess of the slide portion 51 and the recess or protrusion of the bracket 20 can be snapped into place. By fitting the protrusion or recess of the slide portion 51 and the recess or protrusion of the bracket 20 in this way, the lamp removal lever 50 can be held in place by the bracket 20 so that it does not move when the lamp removal lever 50 is not slid.

[0045] As shown in Figures 3 and 6, the projection 52 is a connecting portion that connects the slide portion 51 and the ring portion 53. The projection 52 is provided at the end of the slide portion 51. As shown in Figure 3, the projection 52 is inserted through the slit hole 33 of the shade 30. The operation of the lamp removal lever 50 will be described later, but when the lamp removal lever 50 is slid, the projection 52 moves along the slit hole 33. In other words, the projection 52 moves within the slit hole 33 along the longitudinal direction of the shade 30.

[0046] As shown in Figures 5 and 6, the ring portion 53 is annular. As shown in Figure 3, the ring portion 53 is provided at the tip of the projection portion 52. The ring portion 53 is positioned inside the shade 30. The ring portion 53 also faces a part of the lamp 3 in the longitudinal direction of the shade 30. When the lamp removal lever 50 is slid along the light irradiation direction of the lamp 3, the ring portion 53 comes into contact with a part of the lamp 3.

[0047] In this embodiment, only one slit hole 33 is provided for the lamp removal lever 50 and the shade 30. Specifically, the slit hole 33 for the lamp removal lever 50 and the shade 30 is provided to correspond only to the lamp 3 mounted in the first socket 41 (upper lamp 3) and the lamp 3 mounted in the second socket 42 (lower lamp 3).

[0048] The lamp removal lever 50 is made of a metal or resin material. The lamp removal lever 50 may have a structure in which multiple members made of metal or resin material are connected, or it may have a one-piece structure molded integrally from a resin material.

[0049] As shown in Figures 2 and 3, a first optional member 61 and a second optional member 62 are attached to the shade 30. The first optional member 61 is positioned to cover the first opening 31 of the shade 30. The second optional member 62 is positioned to cover the second opening 32 of the shade 30.

[0050] The first optional member 61 and the second optional member 62 are fixed to the shade 30. Specifically, as shown in Figure 3, screw grooves (threaded portions) are formed on the inner circumferential surfaces of the ends of the shade 30 on the first opening 31 side and the end on the second opening 32 side. Screw grooves (threaded portions) are also formed on the outer circumferential sides of the first optional member 61 and the second optional member 62. Therefore, the first optional member 61 can be fixed to the shade 30 by rotating it and screwing it into the first opening 31 of the shade 30. Similarly, the second optional member 62 can be fixed to the shade 30 by rotating it and screwing it into the second opening 32 of the shade 30. The first optional member 61 and the second optional member 62 can be removed from the shade 30 by rotating them in the opposite direction.

[0051] Each of the first optional member 61 and the second optional member 62 is positioned to face the lens 3c of the lamp 3. Specifically, the first optional member 61 is positioned to face the lens 3c of the lamp 3 located above. The second optional member 62 is positioned to face the lens 3c of the lamp 3 located below.

[0052] Each of the first optional member 61 and the second optional member 62 is an optical member that controls the light distribution of the light emitted from the lamp 3. For example, each of the first optional member 61 and the second optional member 62 is a translucent, milky white diffusion member. As a result, the light emitted from the lamp 3 and incident on the first optional member 61 and the second optional member 62 is diffused (scattered) by the first optional member 61 and the second optional member 62 while passing through them. In this embodiment, the first optional member 61 and the second optional member 62 are solid cylindrical diffusion members.

[0053] Furthermore, as shown in Figure 3, an annular first elastic ring 61a may be inserted between the outer peripheral surface of the first optional member 61 and the inner peripheral surface of the end of the shade 30 on the side of the first opening 31. Similarly, an annular second elastic ring 62a may be inserted between the outer peripheral surface of the second optional member 62 and the inner peripheral surface of the end of the shade 30 on the side of the second opening 32. This prevents water, dust, and the like from entering the shade 30 through the first opening 31 and the second opening 32, respectively. The first elastic ring 61a and the second elastic ring 62a are made of elastically deformable elastic members. The first elastic ring 61a and the second elastic ring 62a are made of, for example, elastomer. Specifically, silicone rubber or urethane rubber can be used as the material for the first elastic ring 61a and the second elastic ring 62a.

[0054] The lighting fixture 2 configured in this way can be installed on the wall surface 100 as follows. First, only the base 10 is fixed to the wall surface 100 with screws. Next, the bracket 20, on which the shade 30 containing the first socket 41 and the second socket 42 is fixed with screws 83, is fitted onto the base 10 fixed to the wall surface 100, and the bracket 20 and base 10 are fixed together with screws 81. This allows the lighting fixture 2 to be installed on the wall surface 100. Note that the lamp removal lever 50 is installed between the bracket 20 and the shade 30 before the bracket 20 and base 10 are fixed together with screws 81.

[0055] The lamp 3 may be attached to the first socket 41 and the second socket 42 in advance before the lighting fixture 2 is installed on the wall surface 100, or it may be attached to the first socket 41 and the second socket 42 after the lighting fixture 2 is installed on the wall surface 100. Similarly, the first optional member 61 and the second optional member 62 may be attached to the shade 30 in advance before the lighting fixture 2 is installed on the wall surface 100, or they may be attached to the shade 30 after the lighting fixture 2 is installed on the wall surface 100.

[0056] In this manner, lamps 3 are installed in the lighting fixture 2. Specifically, lamps 3 are installed in the first socket 41 and the second socket 42, respectively. The configuration of lamps 3 and the first socket 41 will now be explained using Figures 7 and 8, with reference to Figure 3. Figures 7 and 8 are perspective views showing the configuration of lamps 3 and the first socket 41. Note that the second socket 42 has the same structure as the first socket 41, so the explanation of the second socket 42 will be omitted.

[0057] The first socket 41 has a socket function that corresponds to the base of the lamp 3. Specifically, as shown in Figure 7, the housing of the first socket 41 has a pair of elongated holes 41a formed therein as receiving holes for the pair of power supply pins 3d (see Figure 8) of the lamp 3. By inserting the pair of power supply pins 3d of the lamp 3 into the pair of elongated holes 41a and rotating the lamp 3, each of the pair of power supply pins 3d can be connected to each of the pair of connection terminals of the first socket 41. In this way, the first socket 41 and the lamp 3 are electrically and mechanically connected. The same applies when mounting the lamp 3 in the second socket 42.

[0058] Lamp 3 is the light source of the lighting device 1. Lamp 3 is an LED lamp using an LED (Light Emitting Diode). In this embodiment, Lamp 3 is a compact LED lamp with an overall elongated shape. As an example, the external dimensions of Lamp 3 are such that the diameter φ is 50 mm or less. In this embodiment, the external dimensions of Lamp 3 are such that the diameter φ is 45 mm.

[0059] Furthermore, although Lamp 3 is a compact type, it emits illumination light with a high luminous flux equivalent to or greater than a 60-watt (60W) incandescent bulb. Specifically, Lamp 3 can emit illumination light equivalent to a 100-watt incandescent bulb.

[0060] As shown in Figures 3, 7, and 8, the lamp 3 comprises a housing 3a, a light-emitting part 3b held in the housing 3a, a lens 3c positioned opposite the light-emitting part 3b, a pair of power supply pins 3d that receive power to make the light-emitting part 3b emit light, and a drive circuit 3e for driving the light-emitting part 3b.

[0061] The housing 3a is an outer enclosure member that constitutes the outer casing of the lamp 3. The housing 3a is cylindrical in shape. The housing 3a holds the light-emitting part 3b and the lens 3c. The drive circuit 3e is also housed inside the housing 3a. The housing 3a is made of resin or metal material.

[0062] The light-emitting unit 3b emits light of a predetermined color. In this embodiment, the light-emitting unit 3b emits white light. The light emitted by the light-emitting unit 3b becomes the illumination light of the lamp 3. The light-emitting unit 3b is an LED module composed of LEDs, and has a substrate and one or more LED elements mounted on the substrate. In this embodiment, the light-emitting unit 3b is a COB (Chip On Board) type LED module, and has a substrate, a plurality of LED chips directly mounted on the substrate as LED elements, and a sealing member that seals the plurality of LED chips. In this case, when a blue LED chip that emits blue light is used as the LED chip, the sealing member is made of a resin material containing a yellow phosphor. As a result, white light is emitted from the light-emitting unit 3b. The light emitted from the light-emitting unit 3b is incident on the lens 3c.

[0063] The light-emitting unit 3b was a COB type LED module, but is not limited to this. For example, the light-emitting unit 3b may be an SMD (Surface Mount Device) type LED module. When the light-emitting unit 3b is an SMD type LED module, the light-emitting unit 3b has a substrate and one or more SMD type light-emitting elements mounted on the substrate as LED elements. An SMD type light-emitting element has, for example, a resin package (container), an LED chip (e.g., a blue LED chip) mounted in a recess of the package, and a sealing member (e.g., the phosphor-containing resin mentioned above) enclosed in the recess of the package.

[0064] The lens 3c is a light-transmitting optical component. The lens 3c transmits light emitted from the light-emitting part 3b. In this embodiment, the lens 3c is a focusing lens that concentrates the light emitted from the light-emitting part 3b. The lens 3c is made of a light-transmitting material. Specifically, the lens 3c is made of a transparent resin material such as acrylic or polycarbonate, or a glass material.

[0065] Alternatively, a light-transmitting cover may be provided instead of the lens 3c. In this case, the light-transmitting cover may be a transparent cover that does not diffuse light, or a diffuse cover that does diffuse light.

[0066] The pair of power supply pins 3d (electrode pins) are conductive pins that receive power from outside the lamp 3 to illuminate the light-emitting part 3b. For example, the pair of power supply pins 3d receive AC power from the first socket 41 or the second socket 42. The pair of power supply pins 3d and the drive circuit 3e are electrically connected by lead wires or the like. The pair of power supply pins 3d are also connection pins for connecting the lamp 3 to the first socket 41 or the second socket 42. Each power supply pin 3d is electrically and mechanically connected to the first socket 41 or the second socket 42. The lamp 3 is held in the first socket 41 or the second socket 42 by the connection of the power supply pins 3d to the first socket 41 or the second socket 42. Each power supply pin 3d is a T-shaped pin with a disc-shaped large diameter portion at its tip.

[0067] In this embodiment, lamp 3 has a base similar to the GX53 type base. Therefore, the distance between the pair of power supply pins 3d is set to a predetermined length. However, in this embodiment, the pair of power supply pins 3d do not correspond to the GX53 type base (where the distance between the pair of power supply pins is 53 mm), and the distance between the pair of power supply pins 3d is 27 mm.

[0068] The drive circuit 3e is a power supply circuit for causing the light-emitting unit 3b to emit light, and supplies a predetermined amount of power to the light-emitting unit 3b. The drive circuit 3e converts AC power (for example, AC100V commercial AC power) received from the first socket 41 or the second socket 42 via a pair of power supply pins 3d into DC power, and supplies the DC power to the light-emitting unit 3b. As a result, the light-emitting unit 3b emits light.

[0069] Furthermore, a milky white cover may be provided at the tip of lamp 3 to conceal it.

[0070] Lamp 3 is mounted in the first socket 41 and the second socket 42, respectively. Specifically, the lamp 3 mounted in the first socket 41 is installed in the first socket 41 with the lens 3c facing upwards. The lamp 3 mounted in the second socket 42 is installed in the second socket 42 with the lens 3c facing downwards.

[0071] Furthermore, the lamp 3 can be detachably attached to the first socket 41 and the second socket 42. In other words, the lamp 3 can be attached to the first socket 41 or the second socket 42, or removed from the first socket 41 or the second socket 42. In this embodiment, since the lamp 3 has a base conforming to the GX53 type base, when attaching the lamp 3 to the first socket 41 or the second socket 42, the lamp 3 can be attached to the first socket 41 or the second socket 42, or removed from the first socket 41 or the second socket 42, by rotating the lamp 3 horizontally in a plane parallel to the ceiling or floor surface.

[0072] Specifically, when attaching the lamp 3 to the first socket 41 or the second socket 42, the first optional member 61 and the second optional member 62 are removed from the shade 30. Then, the lamp 3 is inserted into the shade 30 by grasping the pair of protrusions 3c1 (see Figure 7) provided on the surface of the lens 3c of the lamp 3 with one's hand, and the power supply pin 3d of the lamp 3 is inserted into the elongated hole 41a of the first socket 41 (or the elongated hole of the second socket 42). By rotating the lamp 3 clockwise, the lamp 3 can be attached to the first socket 41 or the second socket 42.

[0073] On the other hand, when removing the lamp 3 from the first socket 41 or the second socket 42, the lamp 3 can be removed from the first socket 41 or the second socket 42 by rotating the lamp 3 mounted in the first socket 41 or the second socket 42 counterclockwise. This allows the lamp 3 to be removed from the shade 30.

[0074] Here, we will explain how to remove the lamp 3 (upward-facing lamp 3) installed in the first socket 41 from the shade 30, using Figure 9. Figure 9 is a diagram illustrating how to remove the lamp 3 installed in the first socket 41 from the shade 30.

[0075] First, remove the first optional member 61 from the shade 30. Specifically, as shown in Figure 9(a), rotate the first optional member 61 to loosen the first optional member 61 from the shade 30, and as shown in Figure 9(b), remove the first optional member 61 from the first opening 31 of the shade 30.

[0076] Next, although not shown in the diagram, by grasping the pair of protrusions 3c1 (see Figure 7) on the surface of the lens 3c of the lamp 3 with your hand and rotating the lamp 3, the connection between the pair of power supply pins 3d of the lamp 3 and the pair of connection terminals of the first socket 41 is released, and the pair of power supply pins 3d of the lamp 3 come out of the elongated holes 41a of the first socket 41, making it possible to remove the lamp 3 from the first socket 41. Note that since the lamp 3 is located on the upper side of the first socket 41, in this state the lamp 3 remains resting on the first socket 41 due to its own weight.

[0077] Next, as shown in Figure 9(c), the lamp removal lever 50 is moved in the direction of light irradiation of the lamp 3. Specifically, the lamp removal lever 50 is slid by grasping the knob portion 51a of the lamp removal lever 50 and pulling it upward. At this time, as the lamp removal lever 50 slides upward, the ring portion 53 of the lamp removal lever 50 (see Figures 3 and 5) comes into contact with the bottom of the lamp 3, and in this state, the projection portion 52 of the lamp removal lever 50 moves through the slit hole 33 of the shade 30, causing the lamp 3 to be lifted upward by the ring portion 53. As a result, as shown in Figure 9(c), the upper part of the lamp 3 pops out from the shade 30 and is exposed from the shade 30.

[0078] Subsequently, as shown in Figure 9(d), the lamp 3 can be removed from the shade 30 by grasping the upper part of the lamp 3 that protrudes from the shade 30 with one's hand and lifting the lamp 3. In this way, as the lamp removal lever 50 moves in the direction of light irradiation of the lamp 3, the ring portion 53 of the lamp removal lever 50 comes into contact with a part of the lamp 3, and the lamp 3 is removed from the shade 30. As a result, even if the lamp 3 is located above the first socket 41 inside the shade 30, the lamp 3 can be easily removed from the shade 30 by operating the lamp removal lever 50. As a result, the lamp 3 can be easily replaced.

[0079] In particular, in this embodiment, the lamp 3 is a compact LED lamp with an overall elongated shape, and the shade 30 is also an elongated cylindrical shape. As shown in Figure 3, the lamp 3 is crampedly housed inside the shade 30. That is, the maximum diameter of the lamp 3 and the inner diameter of the shade 30 are approximately the same, resulting in a narrow space between the lamp 3 and the shade 30. In this embodiment, the width of the gap between the lamp 3 and the shade 30 is 5 mm or less. Specifically, the gap between the outermost surface of the outermost part of the lamp 3 and the inner surface of the shade 30 is 5 mm or less, a gap that prevents a person's finger from entering. Therefore, when replacing the lamp 3 installed in the first socket 41, the user cannot grab the side of the lamp 3 and remove it from the shade 30. Even in such a case, with the lighting device 1 in this embodiment, the lamp 3 can be easily removed from the shade 30 and replaced by operating the lamp removal lever 50.

[0080] Furthermore, to remove the lamp 3 (downward-facing lamp 3) mounted in the second socket 42 from the shade 30, simply rotating the lamp 3 will allow its own weight to remove it from the shade 30. Specifically, in Figure 3, by removing the second optional member 62 from the shade 30 and grasping the pair of protrusions 3c1 (see Figure 7) on the surface of the lens 3c of the lamp 3 mounted in the second socket 42 with your hand and rotating the lamp 3, the connection between the pair of power supply pins 3d of the lamp 3 and the pair of connection terminals of the second socket 42 is released, and the pair of power supply pins 3d of the lamp 3 come out of the elongated holes of the second socket 42. As a result, the lamp 3 is removed from the second socket 42 by its own weight and falls. Consequently, the lamp 3 can be removed from the second opening 32 of the shade 30.

[0081] As described above, the lighting device 1 according to this embodiment comprises a cylindrical shade 30, a first socket 41 disposed inside the shade 30, a lamp 3 disposed inside the shade 30 and detachably mounted in the first socket 41, and a lamp removal lever 50 for removing the lamp 3 from the shade 30.

[0082] With this configuration, even if a cylindrical shade 30 is used, the lamp 3 can be easily removed from the shade 30 using the lamp removal lever 50. Therefore, even if the lamp 3 and the shade 30 are close together and the space between them is narrow, the lamp 3 can be easily replaced. In addition, by bringing the lamp 3 and the shade 30 close together, the heat generated by the lamp 3 can be efficiently conducted to the shade 30 for heat dissipation. In other words, the lighting device 1 according to this embodiment can achieve both heat dissipation of the lamp 3 and ease of lamp replacement. Moreover, since the lighting device 1 according to this embodiment uses a cylindrical shade 30, a lighting device 1 with excellent design can also be realized.

[0083] Furthermore, the lighting device 1 according to this embodiment has a first socket 41 and a second socket 42 arranged inside the shade 30, with a lamp 3 (first lamp) mounted in the first socket 41 and a lamp 3 (second lamp) mounted in the second socket 42.

[0084] This configuration allows the two lamps 3 to illuminate in two directions. For example, the illumination can be directed upwards and downwards.

[0085] Furthermore, in the lighting device 1 according to this embodiment, the shade 30 has a slit hole 33 extending along the longitudinal direction of the shade 30, and the lamp removal lever 50 has a projection 52 that is inserted into the slit hole 33 and moves along the slit hole 33, and a ring portion 53 that is located inside the shade 30 and provided on the projection 52. When the lamp removal lever 50 moves in the direction of light irradiation of the lamp 3, the ring portion 53 of the lamp removal lever 50 comes into contact with a part of the lamp 3, and the lamp 3 is removed from the shade 30.

[0086] This allows the lamp 3 to be easily removed from the shade 30 simply by moving the lamp removal lever 50 in the direction of light irradiation of the lamp 3.

[0087] Furthermore, the lighting device 1 according to this embodiment includes a base 10 that is attached to a wall surface 100 and a bracket 20 fixed to the base 10, and the shade 30 is fixed to the bracket 20.

[0088] With this configuration, after the base 10 is installed on the wall surface 100, the bracket 20 to which the shade 30 is attached can be fixed to the base 10. This makes it easy to install the lighting device 1 on the wall surface 100.

[0089] Furthermore, in the lighting device 1 according to this embodiment, a portion of the lamp removal lever 50 is positioned between the bracket 20 and the shade 30.

[0090] This configuration allows the lamp removal lever 50 to be hidden between the bracket 20 and the shade 30, making the lamp removal lever 50 less conspicuous. This prevents the aesthetic appeal of the lighting device 1 from being negatively affected by the presence of the lamp removal lever 50.

[0091] Furthermore, in this embodiment, the sliding portion 51 that forms the body of the lamp removal lever 50 is positioned between the bracket 20 and the shade 30, and the knob portion 51a of the lamp removal lever 50 is exposed. The knob portion 51a is also located above the upper end plate of the bracket 20.

[0092] This makes the lamp removal lever 50 less conspicuous, and the exposed knob portion 51a allows for easy operation of the lamp removal lever 50.

[0093] Furthermore, in the lighting device 1 according to this embodiment, the base 10 has an insertion hole 12 through which an electric wire 71 for supplying power to the lamp 3 is inserted, and the insertion hole 12 is facing the center of the shade 30 in the longitudinal direction.

[0094] This configuration allows the internal structure of the shade 30 to be symmetrical in the longitudinal direction of the shade 30. Specifically, the internal structure of the shade 30 can be made vertically symmetrical. Furthermore, because the insertion hole 12 faces the center of the shade 30 in the longitudinal direction, the end faces of the shades 30 can be aligned when multiple lighting devices 1 are installed side by side vertically.

[0095] In this embodiment of the lighting device 1, the lamp removal lever 50 is provided only for the lamp 3 mounted in the first socket 41. However, if the lighting device 1 is installed horizontally, the lamp removal lever 50 may also be provided for the lamp 3 mounted in the second socket 42. In other words, two lamp removal levers 50 corresponding to two lamps 3 may be provided.

[0096] Furthermore, in the lighting device 1 according to this embodiment, a first optional member 61 for controlling the light distribution of light emitted from the lamp 3 is attached to the first opening 31 of the shade 30. In addition, a second optional member 62 for controlling the light distribution of light emitted from the lamp 3 is attached to the second opening 32 of the shade 30.

[0097] With this configuration, the atmosphere of the illumination light emitted from the lighting device 1 can be changed simply by attaching the first optional member 61 or the second optional member 62 to the shade 30.

[0098] (Embodiment 2) Next, the lighting device 1A according to Embodiment 2 will be described using Figures 10 to 12. Figure 10 is a diagram showing the lighting device 1A according to Embodiment 2 when installed on a wall surface 100. Figure 10 shows the lighting device 1 when it is lit. Figure 11 is a perspective view of the lighting device 1A according to Embodiment 2. Figure 12 is a cross-sectional view of the lighting device 1A according to Embodiment 2.

[0099] As shown in Figure 10, the lighting device 1A in this embodiment is a bracket-type lighting device installed on the wall surface 100, similar to the lighting device 1 in Embodiment 1 described above. In this embodiment as well, the optical axis of the lighting device 1A is vertical, and it emits illumination light in the vertical direction. However, unlike the lighting device 1 in Embodiment 1 described above, the lighting device 1A in this embodiment emits illumination light in only one of the two directions: upward or downward. In Figure 10, the lighting device 1A emits illumination light only downward and does not emit illumination light upward.

[0100] As shown in Figures 11 and 12, the lighting device 1A and lighting fixture 2A according to this embodiment are configured without the second socket 42, the second optional member 62, and the second elastic ring 62a compared to the lighting device 1 and lighting fixture 2 in Embodiment 1. Therefore, the lighting device 1A according to this embodiment also does not include the lamp 3 that is mounted in the second socket 42.

[0101] Furthermore, while the lighting device 1 in Embodiment 1 was installed with the first optional member 61 positioned on the upper side, in the lighting device 1A of this embodiment, the first optional member 61 is installed with the lower side. In other words, the lighting device 1A of this embodiment is installed on the wall surface 100 with the shade 30 of the lighting device 1 in Embodiment 1 inverted vertically.

[0102] Furthermore, the lighting device 1A according to this embodiment is equipped with a base 10, a bracket 20, a shade 30, and a lamp removal lever 50, similar to the lighting device 1 in the first embodiment described above.

[0103] Furthermore, the lighting device 1A according to this embodiment does not include a second socket 42 and a lamp 3 mounted in the second socket 42, nor does it include a second optional member 62. As a result, there is a risk that foreign matter such as dust may enter the shade 30 through the second opening 32 of the shade 30 located on the upper side. Therefore, the lighting device 1A according to this embodiment is provided with a cover portion 90 that is positioned to close the second opening 32 of the shade 30. The cover portion 90 is fitted into the second opening 32 of the shade 30. Specifically, screw grooves (threaded portions) are formed on the outer peripheral side surface of the cover portion 90. As a result, the cover portion 90 can be fixed to the shade 30 by rotating the cover portion 90 and screwing it into the second opening 32 of the shade 30. Also, the cover portion 90 can be removed from the shade 30 by rotating it in the opposite direction.

[0104] The lid portion 90 is made of a metal or resin material. In this embodiment, the lid portion 90 is made of a metal material. For example, the lid portion 90 is made of aluminum.

[0105] As described above, the lighting device 1A according to this embodiment, like the lighting device 1 in Embodiment 1, comprises a cylindrical shade 30, a first socket 41 disposed inside the shade 30, a lamp 3 disposed inside the shade 30 and detachably mounted in the first socket 41, and a lamp removal lever 50 for removing the lamp 3 from the shade 30.

[0106] This allows the lamp 3 to be easily removed from the shade 30 using the lamp removal lever 50. Therefore, even if the space between the lamp 3 and the shade 30 is narrow, the lamp 3 can be easily replaced.

[0107] In this embodiment, the lighting device 1A is installed on the wall surface 100 such that the lamp 3 is located below the first socket 41. Therefore, by simply rotating the lamp 3 mounted in the first socket 41, the lamp 3 can be removed from the shade 30 by its own weight. In other words, the lamp 3 can be removed from the shade 30 without using the lamp removal lever 50. However, there are cases where the lamp 3 does not come out of the shade 30 by its own weight alone. In such cases, the lamp 3 can be easily removed from the shade 30 by using the lamp removal lever 50.

[0108] Furthermore, in the lighting device 1A of this embodiment, the lamp 3 is installed on the wall surface 100 so that it is located below the first socket 41, and the shade 30 of the lighting device 1 in the above embodiment 1 is inverted vertically. For this reason, in this embodiment, the lamp removal lever 50 is also inverted vertically compared to the above embodiment 1. Therefore, it is preferable that the lamp removal lever 50 is configured so that it does not slide due to its own weight. For example, a protrusion or recess may be provided on the bracket 20 side surface of the sliding portion 51 of the lamp removal lever 50, and a recess or protrusion may be provided on the sliding portion 51 side surface of the bracket 20, so that the protrusion or recess of the sliding portion 51 and the recess or protrusion of the bracket 20 are fitted together by light press-fitting. In this case, the fitted state between the protrusion or recess of the sliding portion 51 and the recess or protrusion of the bracket 20 can be easily released by sliding the lamp removal lever 50 downwards. Furthermore, by sliding the lamp removal lever 50 upward, the protrusion or recess of the sliding part 51 can be snapped into place with the recess or protrusion of the bracket 20. By engaging the protrusion or recess of the sliding part 51 with the recess or protrusion of the bracket 20 in this way, the lamp removal lever 50 can be held in place by the bracket 20 when it is not being slid.

[0109] Furthermore, in this embodiment, the lighting device 1A may be installed on the wall surface 100 such that the lamp 3 is located above the first socket 41. In other words, in Figure 10, the lighting device 1A may be installed on the wall surface 100 inverted so that the first optional member 61 is located above. In this case, as with the first embodiment described above, the lamp 3 is located above the first socket 41, so when removing the lamp 3 from the shade 30, the lamp removal lever 50 is slid.

[0110] (modified version) Although the lighting device according to the present invention has been described above based on Embodiments 1 and 2, the present invention is not limited to Embodiments 1 and 2.

[0111] For example, in embodiments 1 and 2 described above, the lamp removal lever 50 had a ring portion 53 connected to the tip of the projection 52, but it is not limited to this. Specifically, as shown in Figure 13, the lamp removal lever 50B may not have a ring portion connected to the tip of the projection 52, and the tip of the projection 52 may be an open end. Figure 13 is a perspective view of a modified lamp removal lever 50B. Even with the lamp removal lever 50B shown in Figure 13, the lamp 3 can be removed from the shade 30. In this case, as the lamp removal lever 50B moves in the direction of light irradiation of the lamp 3, the projection 52 comes into contact with a part of the lamp 3 and the lamp 3 is removed from the shade 30.

[0112] Furthermore, in embodiments 1 and 2 described above, the lamp 3 was removed from the shade 30 using a lamp removal lever 50, but this is not limited to this. For example, the lamp 3 may be removed from the shade 30 using a lamp removal member 50C shown in Figures 14 and 15. Figure 14 is a perspective view of the lamp removal member 50C. Figure 15 is a partial cross-sectional view of a modified lighting device 1C. As shown in Figure 15, the lighting device 1C according to this modified example is a lighting device installed on a wall surface 100, and comprises a cylindrical shade 30C, a first socket 41 disposed inside the shade 30C, a lamp 3 disposed inside the shade 30C and detachably mounted on the first socket 41, and a lamp removal member 50C for removing the lamp 3 from the shade 30C. The lamp removal member 50C is attached to the lamp 3. Specifically, the lamp removal member 50C is cylindrical, and its insertion wall 50a is inserted into the gap 3f between the housing 3a and the lens 3c of the lamp 3, thereby fixing it to the lamp 3. This allows the lamp 3, which is fixed to the lamp removal member 50C, to be removed from the shade 30C by rotating and pulling out the lamp removal member 50C. The cylindrical lamp removal member 50C also functions as a baffle to prevent glare. Therefore, the lamp removal member 50C may be made of, for example, a black resin material. Furthermore, since this modified example does not include a lamp removal lever 50, the shade 30C in this modified example does not have a slit hole 33. Although not shown, the lighting device 1C in this modified example may or may not include a base 10, a bracket 20, a second socket 42, and a second optional member 62.

[0113] Furthermore, in the above embodiment 1, the first optional member 61 and the second optional member 62 attached to the shade 30 were solid cylindrical diffusion members, but the invention is not limited to these.

[0114] Specifically, as shown in Figures 16, 17, and 18, the optional member 65 attached to the first opening 31 or the second opening 32 of the shade 30 may be a baffle to prevent glare. Figures 16 and 17 are perspective views of the optional member 65 according to Modification 1. Figure 18 is a diagram showing the configuration of the optional member 65 according to Modification 1. In Figure 18, (a) is a plan view of the optional member 65, (b) is a front view of the optional member 65, and (c) is a bottom view of the optional member 65. As shown in Figures 16, 17, and 18, the optional member 65 in this modification has a first cylindrical portion 65a and a second cylindrical portion 65b located inside the first cylindrical portion 65a. The first cylindrical portion 65a and the second cylindrical portion 65b are connected by three connecting bridges. The optional member 65 is made of, for example, a black resin material. Although not shown in the figure, the outer surface of the optional member 65 has screw grooves formed therein for screwing it into the first opening 31 of the shade 30. The left side view, right side view, and rear view of the optional member 65 are all the same as those in Figure 18(b).

[0115] Furthermore, as shown in Figures 19, 20, 21, and 22, the optional member 66 attached to the first opening 31 or second opening 32 of the shade 30 may be a lens that can produce a sparkling effect. Figures 19 and 20 are perspective views of the optional member 66 according to Modification 2. Figure 21 is a cross-sectional view of the optional member 66 according to Modification 2. Figure 22 is a diagram showing the configuration of the optional member 66 according to Modification 2. In Figure 22, (a) is a plan view of the optional member 66, (b) is a front view of the optional member 66, and (c) is a bottom view of the optional member 66. As shown in Figures 19, 20, 21, and 22, the optional member 66 in this modification is a cylindrical transparent member with a recess 66a formed on the light-emitting side. The optional member 66 can be made of, for example, transparent acrylic resin. The left side view, right side view, and rear view of the optional member 66 are all the same as (b) in Figure 22.

[0116] Furthermore, as shown in Figures 23 and 24, the optional member 67 attached to the first opening 31 or second opening 32 of the shade 30 may be a lens that can produce a greater sparkling effect. Figure 23 is a perspective view of the optional member 67 according to Modification 3. Figure 24 is a cross-sectional view of the optional member 67 according to Modification 3. As shown in Figures 23 and 24, the optional member 67 in this modification is a cylindrical bubble rod having a plurality of bubble-like pores (air layers) inside. The optional member 67 can be made of, for example, transparent acrylic resin.

[0117] The optional members 65, 66, and 67 shown in Figures 16 to 24 can also be used in Embodiment 2.

[0118] Furthermore, in Embodiment 1 described above, the shade 30 was fitted with the first optional member 61 and the second optional member 62, but this is not limited to this. In other words, the shade 30 may not be fitted with the first optional member 61 and the second optional member 62, and the first opening 31 and the second opening 32 of the shade 30 may be open. In this case, the light emitted from the two lamps 3 will be directly irradiated through the first opening 31 and the second opening 32 of the shade 30. Also, the shade 30 may be fitted with only one of the first optional member 61 and the second optional member 62. Similarly, in Embodiment 2 described above, the shade 30 may not be fitted with the first optional member 61.

[0119] Furthermore, although the shade 30 did not have light-transmitting properties in the above embodiments 1 and 2, the shade 30 may have light-transmitting properties. By having light-transmitting properties, the shade 30 can transmit light from the lamp 3.
