[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that each of the embodiments described below shows a specific example of the present invention. Therefore, the numerical values, components, the arrangement and connection of the components, steps, and the order of steps 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, components that are not described in the independent claims that represent the highest concept of the present invention will be described as optional components.

[0013] Note that each figure is a schematic diagram and is not necessarily an exact illustration. Furthermore, in each figure, substantially the same components are assigned the same reference numerals, and redundant explanations are omitted or simplified. Furthermore, in each figure, the X-axis, Y-axis, and Z-axis represent the three axes of a three-dimensional Cartesian coordinate system, and in this embodiment, the Z-axis direction is the vertical direction, and the direction perpendicular to the Z-axis (the direction parallel to the XY plane) is the horizontal direction. The X-axis and Y-axis are axes that are mutually orthogonal and are both orthogonal to the Z-axis. Note that in this specification, the terms "up" and "down" do not necessarily refer to the upward direction (vertically upward) and downward direction (vertically downward) in absolute spatial recognition.

[0014] (Embodiment 1) First, the configuration of an LED lighting fixture 1 according to embodiment 1 will be described with reference to Figs. 1 to 3. Fig. 1 is a perspective view of the LED lighting fixture 1 according to embodiment 1. Fig. 2 is an exploded perspective view of the LED lighting fixture 1. Fig. 3 is a cross-sectional view of the LED lighting fixture 1. Fig. 3 shows a cross section of the LED lighting fixture 1 taken along a plane parallel to the short side direction of the LED lighting fixture 1.

[0015] An LED lighting fixture 1 according to this embodiment includes a fixture body 2 and an LED lighting device 3 attached to the fixture body 2, as shown in FIGS.

[0016] The fixture body 2 holds the LED lighting device 3. The fixture body 2 is installed at a predetermined location in a building. The LED lighting fixture 1 in this embodiment is a ceiling-mounted lighting fixture. Therefore, the fixture body 2 is attached to the ceiling inside a room using bolts or the like.

[0017] In this embodiment, the fixture body 2 is made of sheet metal and is formed into a long, flat box shape in the Y-axis direction by bending the metal plate or the like. As shown in FIG. 2, the fixture body 2 is provided with a recess 2a having a rectangular opening. The recess 2a is provided elongated along the longitudinal direction of the fixture body 2. The recess 2a is a storage section for storing the LED lighting device 3 and is provided over substantially the entire length of the fixture body 2. Furthermore, as shown in FIGS. 2 and 3, on both sides of the recess 2a in the width direction of the fixture body 2, there are provided inclined surfaces 2b that extend from the opening edge of the recess 2a and slope upward (towards the ceiling) as they go outward.

[0018] The LED lighting device 3 is a light source unit that uses an LED as a light source. The LED lighting device 3 is detachably attached to the recess 2a of the fixture body 2. For example, the LED lighting device 3 can be attached to the recess 2a of the fixture body 2, or the LED lighting device 3 attached to the recess 2a of the fixture body 2 can be detached from the recess 2a. The LED lighting device 3 and the fixture body 2 can be fixed by hooking and engaging a hook metal fitting 5 and an elastic holding member 6 (a kick spring in this embodiment) provided on the LED lighting device 3 onto the fixture body 2.

[0019] As shown in FIG. 3, the LED lighting device 3 emits light using power supplied from a power supply device 4 housed in the fixture body 2. The power supply device 4 is an example of an electrical functional component, and supplies power to the LED lighting device 3. The power supply device 4 is disposed on the rear side of the LED lighting device 3. Specifically, the power supply device 4 is disposed in a recess 2a of the fixture body 2. In this embodiment, the power supply device 4 is attached to the LED lighting device 3 as a part of the LED lighting device 3, and is integrated with the LED lighting device 3. Note that the power supply device 4 may not be integrated with the LED lighting device 3, but may be disposed in the fixture body 2 separately from the LED lighting device 3.

[0020] The power supply device 4 is configured with a power supply circuit that generates power for emitting light from the LED lighting device 3. For example, the power supply device 4 has a printed circuit board on which multiple electronic components are mounted and a circuit case that houses the printed circuit board. The power supply device 4 converts AC power from an external power source such as a commercial power source into DC power of a predetermined level by rectifying, smoothing, and stepping down the power, and supplies the DC power to the LED lighting device 3.

[0021] AC power is supplied to the power supply device 4 via a power terminal block 8 (see FIG. 2) connected to a power line that is inserted from above the ceiling into a through-hole in the fixture body 2 and drawn out to the recess 2a of the fixture body 2. The power terminal block 8 is installed in the recess 2a of the fixture body 2.

[0022] Next, the detailed structure of the LED lighting device 3 will be described using Figs. 4 to 7 while referring to Figs. 1 to 3. Fig. 4 is a perspective view of the LED lighting device 3 according to embodiment 1 as seen from the cover member 30 side, and Fig. 5 is a perspective view of the LED lighting device 3 as seen from the back side. Fig. 6 is a cross-sectional perspective view of the LED lighting device 3. Fig. 7 is an exploded perspective view of the LED lighting device 3.

[0023] 2, 4, and 5, the LED lighting device 3 is a long linear light source called a light bar. The LED lighting device 3 emits light of a predetermined color, such as white light.

[0024] As shown in Figures 3, 6 and 7, the LED lighting device 3 includes a substrate 10, an LED 20 arranged on the substrate 10, a cover member 30 that covers the LED 20, a frame 40 that supports the substrate 10, and an end cap 50.

[0025] The substrate 10 is a mounting substrate for mounting the LEDs 20. In this embodiment, the substrate 10 is formed in a substantially rectangular shape that is elongated in the longitudinal direction (Y-axis direction) of the frame 40. The thickness of the substrate 10 is, for example, 1.0 mm. The length of the substrate 10 may be substantially the same as the overall length of the frame 40 in the longitudinal direction, or a plurality of substrates 10 may be arranged along the longitudinal direction of the frame 40. As shown in FIG. 7, in this embodiment, two substrates 10 are arranged along the longitudinal direction of the frame 40.

[0026] 6 and 7, the substrate 10 has a first surface 10a, which is one surface, and a second surface 10b, which is the other surface facing away from the first surface 10a. The first surface 10a of the substrate 10 is the front surface on which the LEDs 20 are mounted. On the other hand, the second surface 10b of the substrate 10 is the back surface facing the frame 40. In this embodiment, the second surface 10b of the substrate 10 is in contact with the frame 40.

[0027] The substrate 10 is, for example, a printed wiring board (printed circuit board) on which metal wiring is formed in a predetermined pattern. Note that a resist made of an insulating resin material may be formed on the surface of the substrate 10 so as to cover the wiring in order to protect the wiring and ensure a dielectric strength voltage. The substrate 10 may be a single-sided wiring board in which wiring is formed only on the first surface 10a on which the LEDs 20 are mounted, or may be a double-sided wiring board in which wiring is formed on both the first surface 10a and the second surface 10b.

[0028] The base material constituting the substrate 10 may be a resin substrate made of an insulating resin material, a ceramic substrate made of a sintered body of a ceramic material such as alumina, or a metal-based substrate obtained by applying an insulating coating to the surface of a metal substrate made of a metal material such as aluminum or copper.

[0029] When the substrate 10 is made of a resin substrate, examples of the resin substrate that can be used include a glass epoxy substrate (CEM-3, FR-4, etc.) made of glass fiber and epoxy resin, a paper phenol substrate (FR-1, FR-2) made of kraft paper or the like and phenol resin, a paper epoxy substrate (FR-3) made of paper and epoxy resin, or a polyimide substrate made of polyimide, etc. The substrate 10 may be a rigid substrate or a film-like flexible substrate.

[0030] 6 and 7, a plurality of LEDs 20 are mounted on the first surface 10a of the substrate 10. In this embodiment, the plurality of LEDs 20 are mounted in a linear row along the longitudinal direction (Y-axis direction) of the substrate 10 at predetermined intervals. Specifically, the plurality of LEDs 20 are mounted over substantially the entire length of the cover member 30 and the frame 40 in the longitudinal direction. Note that the plurality of LEDs 20 may be mounted in multiple rows along the longitudinal direction of the substrate 10 instead of in a single row.

[0031] The LED 20 is an example of a light-emitting element. In this embodiment, each of the multiple LEDs 20 is an individually packaged LED element (LED light source) with an SMD structure. In this case, each LED 20 includes a white container (package) made of resin or ceramic, an LED chip (bare chip) placed in the container, and a sealing member that seals the LED chip. In this embodiment, the LED 20 is a white LED element that emits white light. In this case, for example, a blue LED chip that emits blue light when powered is used as the LED chip, and a silicone resin (phosphor-containing resin) containing a yellow phosphor such as YAG is used as the sealing member filled in the container.

[0032] The LEDs 20 are covered with a cover member 30. Specifically, all of the LEDs 20 are covered with the cover member 30. The cover member 30 is an example of a light-transmitting cover that transmits light emitted from the LEDs 20. In this embodiment, the cover member 30 is a diffusion cover that not only transmits light but also diffuses light. Therefore, the light from the LEDs 20 that enters the cover member 30 is diffused (scattered) by the cover member 30 and passes through the cover member 30.

[0033] 3 and 6, the cover member 30 covers the substrate 10. Specifically, the cover member 30 is disposed opposite the first surface 10a of the substrate 10 so as to cover the plurality of LEDs 20.

[0034] In this embodiment, the cover member 30 covers the entire substrate 10 on which the LEDs 20 are arranged. As shown in Figures 5 and 6, the cover member 30 also covers the entire frame 40 on which the substrate 10 is arranged. Therefore, the cover member 30, like the substrate 10 and the frame 40, is formed in an elongated shape in the Y-axis direction.

[0035] The cover member 30 is attached to the frame 40. The cover member 30 and the frame 40 form a cylindrical body, and the substrate 10 and the plurality of LEDs 20 mounted on the substrate 10 are housed within this cylindrical body.

[0036] The cover member 30 is attached to the frame 40 so as to cover the substrate 10 and the LEDs 20. As shown in Figures 3 and 6, the cover member 30 has a cover main body 31, an attachment portion 32 connected to the cover main body 31, and an extension piece 33 connected to the attachment portion 32.

[0037] As shown in Fig. 7, the cover main body 31 is elongated in the Y-axis direction and formed in a gutter shape. The cover main body 31 has, for example, a flat, approximately semi-cylindrical shape. Therefore, the cover main body 31 has an elongated rectangular opening end surface extending in the Y-axis direction. Furthermore, the cross-sectional shape of the cover main body 31 when cut along the X-axis direction has a curved shape that is curved in an approximately arc shape.

[0038] As shown in FIGS. 3 and 6 , the cover body 31 includes protrusions 31a that protrude outward in the width direction of the cover body 31 from the mounting portion 32. The protrusions 31a are formed at both ends of the cover body 31 in the short-side direction (width direction). Each protrusion 31a has a recess 31a1 that is recessed on the side opposite the frame 40. If the recess 31a1 is formed, dead insects and foreign matter may accumulate in the recess 31a1, which may cause the short-side ends of the cover body 31 to become dull. Therefore, each protrusion 31a may not have a recess 31a1. In this case, for example, the XZ cross section of the protrusion 31a may be V-shaped, and the ceiling side of the protrusion 31a may be formed to be flush with the extension piece 33 via the mounting portion 32.

[0039] The mounting portion 32 is a portion that is attached to the frame 40. Specifically, the mounting portion 32 is attached to a side plate portion 42 of the frame 40. The mounting portion 32 is also an extension portion that extends from the cover main body portion 31 toward the frame 40.

[0040] A pair of mounting portions 32 are provided on the cover main body 31. Specifically, the mounting portions 32 are formed as a pair of legs that stand on both ends of the cover main body 31 in the short side direction (X-axis direction). Therefore, the pair of mounting portions 32 protrude from the cover main body 31 toward the ceiling. As shown in FIG. 7, each of the pair of mounting portions 32 is formed elongated along the Y-axis direction. The pair of mounting portions 32 have the same length in the Y-axis direction.

[0041] 3, 6, and 7, at least one of the pair of mounting portions 32 has an inclined plate portion 32a (cover inclined plate portion). The inclined plate portion 32a is inclined so as to approach the other of the pair of mounting portions 32 as it moves away from the cover main body portion 31. Specifically, the pair of mounting portions 32 is composed of a first mounting portion 321 and a second mounting portion 322 that are provided opposite each other in the X-axis direction, and of the first mounting portion 321 (one mounting portion 32) and the second mounting portion 322 (the other mounting portion 32), only the first mounting portion 321 has the inclined plate portion 32a.

[0042] The inclined plate portion 32a formed on the first mounting portion 321 is inclined so as to approach the second mounting portion 322 as it moves away from the cover main body portion 31. In other words, the inclined plate portion 32a is inclined so that its tip portion leans toward the inside of the frame 40. The inclined plate portion 32a is inclined at a predetermined inclination angle with respect to the XY plane. The angle (inclination angle) between the extension direction of the inclined plate portion 32a in the XZ cross section and the XY plane is an acute angle less than 90 degrees, for example, equal to or greater than 30 degrees and less than 90 degrees.

[0043] In this embodiment, the first mounting portion 321 further has an orthogonal plate portion 32b (cover orthogonal plate portion) that is orthogonal to the main surface (the XY plane in this embodiment) of the main plate portion 41 of the frame 40. In other words, the orthogonal plate portion 32b is not inclined with respect to the XY plane, and extends from the cover main body portion 31 in a direction parallel to the Z-axis direction. The inclined plate portion 32a is connected to the end of the orthogonal plate portion 32b on the opposite side to the cover main body portion 31 side.

[0044] The inclined plate portion 32a and the orthogonal plate portion 32b of the first mounting portion 321 are each substantially plate-shaped, and a bent portion is formed by the inclined plate portion 32a and the orthogonal plate portion 32b. That is, the first mounting portion 321 is shaped so that the inclined plate portion 32a is bent midway so that it leans inward. The angle formed between the inclined plate portion 32a and the orthogonal plate portion 32b in the XZ cross section is an obtuse angle less than 180 degrees, for example, greater than or equal to 120 degrees and less than 180 degrees.

[0045] On the other hand, the second mounting portion 322 does not have an inclined plate portion 32a like the first mounting portion 321, and extends in a direction parallel to the Z-axis direction from the cover main body portion 31. In other words, the second mounting portion 322 does not have a shape that is bent halfway.

[0046] 6 and 7, each of the pair of mounting portions 32 has a recess 32c into which the tip end of the side plate portion 42 of the frame 40 is fitted. In the present embodiment, the recess 32c is provided at the tip end of each of the pair of mounting portions 32. Specifically, the recess 32c is provided on the inner side of the tip end of each of the pair of mounting portions 32 in the width direction (X-axis direction).

[0047] The tip portions of the pair of side plate portions 42 of the frame 40 are fitted into the recesses 32c. Specifically, the tip portion of the first side plate portion 421 is fitted into the recess 32c of the first mounting portion 321, and the bent portion 42c provided at the tip portion of the second side plate portion 422 is fitted into the recess 32c of the second mounting portion 322. In this manner, the tip portions of the pair of side plate portions 42 are fitted into the recesses 32c of the pair of mounting portions 32, whereby the pair of mounting portions 32 of the cover member 30 and the pair of side plate portions 42 of the frame 40 are engaged and fixed to each other. In the present embodiment, each of the pair of mounting portions 32 of the cover member 30 is located outside each of the pair of side plate portions 42 of the frame 40. Therefore, the pair of mounting portions 32 of the cover member 30 is fixed and held to the frame 40 so as to embrace the frame 40.

[0048] As shown in FIGS. 3 and 6, the extension piece 33 is an extension portion that extends to reach the main plate portion 41 of the frame 40. Specifically, the extension piece 33 extends from the attachment portion 32 along the short-side direction (X-axis direction) of the cover member 30 and abuts against the step portion 41a of the main plate portion 41. Therefore, the extension piece 33 is located more inward than the attachment portion 32. Specifically, the extension piece 33 extends in a direction parallel to the first surface 10a and the second surface 10b of the substrate 10. As an example, the extension piece 33 is a plate-like piece formed with a constant thickness. Note that a step portion is formed in the extension piece 33, but the step portion need not be formed.

[0049] The extension piece 33 functions as a stopper that presses down the main plate portion 41 of the frame 40. In other words, the extension piece 33 prevents the frame 40 from shifting toward the light emission side (floor side) of the LEDs 20. In this embodiment, the extension piece 33 presses down the step portion 41a of the main plate portion 41 from the floor side (light emission side of the LEDs 20) toward the ceiling side, thereby preventing the frame 40 from shifting toward the floor side.

[0050] The extension piece 33 also has the function of preventing insects from entering the space between the cover body 31 of the cover member 30 and the main plate 41 of the frame 40. In other words, by providing the extension piece 33 so as to press down on the main plate 41, a maze structure can be formed in the path that insects can take when they enter through the gap between the mounting portion 32 of the cover member 30 and the side plate 42 of the frame 40, thereby preventing insects from entering the interior.

[0051] Further, the extension pieces 33 stand upright from each of the pair of mounting portions 32. That is, the cover member 30 has a pair of extension pieces 33. In this embodiment, the pair of extension pieces 33 have the same length in the X-axis direction. As shown in FIG. 7, each of the pair of extension pieces 33 is formed elongated along the Y-axis direction. The pair of extension pieces 33 also have the same length in the Y-axis direction. As an example, the pair of extension pieces 33 have the same shape, but are not limited to this. Furthermore, the pair of extension pieces 33 are provided at the same height in the Z-axis direction.

[0052] The cover member 30 is made of a translucent resin material such as acrylic or polycarbonate, or a translucent material such as glass. In this embodiment, the cover member 30 is made of a translucent resin material. In this case, the cover member 30 may be a milky white cover member with a light diffusing material dispersed therein. Such a cover member 30 may be produced by resin molding a translucent resin material mixed with a light diffusing material into a predetermined shape. Light-reflective fine particles such as silica particles may be used as the light diffusing material.

[0053] The cover member 30 may be configured by forming a milky white light-diffusing film containing a light-diffusing material on the surface (inner or outer surface) of the transparent cover, rather than dispersing a light-diffusing material inside. The cover member 30 may also be configured to have light-diffusing properties by applying a diffusing treatment, rather than using a light-diffusing material. For example, the cover member 30 may be configured to have light-diffusing properties by applying a surface treatment such as a texturing treatment to form minute irregularities on the surface of the transparent cover, or by printing a dot pattern on the surface of the transparent cover. Even when the cover member 30 is subjected to a diffusing treatment, it may further contain a light-diffusing material to enhance light-diffusing properties.

[0054] In this embodiment, the cover body 31, the attachment portion 32, and the extension piece 33 that constitute the cover member 30 are integrally formed. Therefore, the cover body 31, the attachment portion 32, and the extension piece 33 are made of the same material.

[0055] The frame 40 is a long support member (base member) that supports the substrate 10. The substrate 10 is attached to the frame 40. Specifically, the substrate 10 is supported by the frame 40 by placing the substrate 10 on the frame 40 and fixing the substrate 10 to the frame 40. In this embodiment, the frame 40 supports not only the substrate 10 but also the cover member 30. Specifically, the cover member 30 is fixed to the frame 40.

[0056] As an example, the frame 40 is a frame made of sheet metal. The frame 40 is formed into a predetermined shape by performing roll forming, press working, or the like on a sheet metal (metal plate) made of, for example, SPCC (Steel Plate Cold Commercial; cold-rolled steel plate). In this embodiment, the frame 40 is formed so that the cross section (XZ cross section) when cut along the X-axis direction is substantially U-shaped. Furthermore, like the substrate 10 and the device main body 2, the frame 40 is formed into an elongated shape in the Y-axis direction. The thickness of the metal plate constituting the frame 40 is, for example, 0.2 mm to 2 mm, and is 0.5 mm in this embodiment.

[0057] 3 to 7, the frame 40 has a plate-shaped main plate portion 41 and a pair of plate-shaped side plate portions 42. As shown in Fig. 7, the main plate portion 41 and the pair of side plate portions 42 are elongated and extend in the Y-axis direction.

[0058] The main plate portion 41 is the main body of the frame 40. A pair of step portions 41a are formed in the width direction (X-axis direction) along the longitudinal direction of the main plate portion 41. The step portions 41a are flat portions. Furthermore, by forming the pair of step portions 41a, a recessed portion 41b is formed in the main plate portion 41. The pair of step portions 41a and the recessed portion 41b are formed over the entire length of the main plate portion 41 in the longitudinal direction.

[0059] 3 and 6, the substrate 10 is attached to the main plate 41. Specifically, the substrate 10 is placed in the recess 41b of the main plate 41. In other words, the main plate 41 supports the substrate 10. In this embodiment, the substrate 10 and the main plate 41 are in contact with each other.

[0060] 7, main plate 41 has claws 43 formed by cutting and raising parts of sheet metal frame 40, and circuit board 10 placed on main plate 41 is fixed to main plate 41 by being locked by claws 43. Main plate 41 also has through holes through which conductive wires are inserted to electrically connect wiring on circuit board 10 to power supply 4.

[0061] The pair of side plates 42 constitute the side surfaces of the frame 40. The pair of side plates 42 protrude from both ends of the main plate 41 in the short direction (X-axis direction) toward the opposite side from the LED 20 (toward the ceiling). In other words, the pair of side plates 42 are formed as a pair of legs that stand on the main plate 41. For example, the pair of side plates 42 and the main plate 41 can be formed by bending a metal plate. As shown in FIG. 7, each of the pair of side plates 42 is formed elongated along the Y-axis direction. The pair of side plates 42 have the same length in the Y-axis direction.

[0062] 3, 6, and 7, at least one of the pair of side plate portions 42 has an inclined plate portion 42a (frame inclined plate portion). The inclined plate portion 42a is inclined so as to approach the other of the pair of side plate portions 42 as it moves away from the main plate portion 41. Specifically, the pair of side plate portions 42 is composed of a first side plate portion 421 and a second side plate portion 422 that are provided opposite each other in the X-axis direction, and of the first side plate portion 421 (one side plate portion 42) and the second side plate portion 422 (the other side plate portion 42), only the first side plate portion 421 has the inclined plate portion 42a.

[0063] The inclined plate portion 42a formed on the first side plate portion 421 is inclined so as to approach the second side plate portion 422 as it moves away from the main plate portion 41. In other words, the inclined plate portion 42a is inclined so that the tip side thereof leans inward of the frame 40. The inclined plate portion 42a is inclined at a predetermined inclination angle with respect to the XY plane. The angle (inclination angle) between the extension direction of the inclined plate portion 42a in the XZ cross section and the XY plane is an acute angle less than 90 degrees, for example, equal to or greater than 30 degrees and less than 90 degrees.

[0064] In the present embodiment, the inclination angle of the inclined plate portion 42a of the first side plate portion 421 of the frame 40 is the same as the inclination angle of the inclined plate portion 32a of the first mounting portion 321 of the cover member 30. Therefore, the inclined plate portion 42a of the first side plate portion 421 is formed along the inclined plate portion 32a of the first mounting portion 321, and the inclined plate portion 42a of the first side plate portion 421 and the inclined plate portion 32a of the first mounting portion 321 are approximately parallel to each other.

[0065] Moreover, in this embodiment, the first side plate portion 421 further has an orthogonal plate portion 42b (frame orthogonal plate portion) that is orthogonal to the main plate portion 41. Specifically, the orthogonal plate portion 42b of the first side plate portion 421 is orthogonal to the main surface (the XY plane in this embodiment) of the step portion 41a or recessed portion 41b of the main plate portion 41. In other words, the orthogonal plate portion 42b is not inclined with respect to the XY plane, and extends from the main plate portion 41 in a direction parallel to the Z-axis direction. The inclined plate portion 42a is connected to an end of the orthogonal plate portion 42b on the opposite side to the main plate portion 41 side.

[0066] The orthogonal plate portion 42b of the first side plate portion 421 in the frame 40 is formed along the orthogonal plate portion 32b of the first mounting portion 321 in the cover member 30, and the orthogonal plate portion 42b of the first side plate portion 421 and the orthogonal plate portion 32b of the first mounting portion 321 are approximately parallel to each other.

[0067] The inclined plate portion 42a and the orthogonal plate portion 42b of the first side plate portion 421 are each substantially plate-shaped, and a bent portion is formed by the inclined plate portion 42a and the orthogonal plate portion 42b. In other words, the first side plate portion 421 is shaped so that the inclined plate portion 42a is bent midway so that it leans inward. The angle between the inclined plate portion 42a and the orthogonal plate portion 42b in the XZ cross section is an obtuse angle less than 180 degrees, for example, 120 degrees or more and less than 180 degrees. It is preferable that there be a space inside the inclined plate portion 42a. It is preferable that components constituting the LED lighting device 3 be arranged in this space inside the inclined plate portion 42a.

[0068] On the other hand, the second side plate portion 422 does not have an inclined plate portion 42a like the first side plate portion 421, and extends from the main plate portion 41 in a direction parallel to the Z-axis direction. In other words, the second side plate portion 422 does not have a shape that is bent halfway. The second side plate portion 422 of the frame 40 is formed overall along the second mounting portion 322 of the cover member 30, and the second side plate portion 422 and the second mounting portion 322 are generally parallel to each other overall.

[0069] 3 and 6, the cover member 30 is attached to the pair of side plate portions 42. Specifically, the attachment portions 32 of the cover member 30 are attached to each of the pair of side plate portions 42.

[0070] In this case, the first side plate portion 421 having the inclined plate portion 42a is attached to the first attachment portion 321 having the inclined plate portion 32a. Specifically, the tip end of the first side plate portion 421 is engaged with and fitted into the recess 32c provided in the first attachment portion 321 of the cover member 30.

[0071] 6 and 7, the second side plate 422 does not have an inclined plate portion and is attached to the second attachment portion 322. Specifically, as shown in Fig. 6 and Fig. 7, the tip of the second side plate 422 is provided with a bent portion 42c that is curled outward, and the bent portion 42c of the second side plate 422 is engaged and fitted into a recess 32c provided in the second attachment portion 322 of the cover member 30 by snap-in.

[0072] In this embodiment, the cover member 30 is fixed to the frame 40 by engaging the tip ends of each of the pair of side plate portions 42 with the recesses 32c of each of the pair of mounting portions 32 of the cover member 30.

[0073] The frame 40 thus configured has a recess 44 surrounded by the main plate 41 and the pair of side plate portions 42. Components such as the power supply 4, the hooking metal fitting 5, and the conductive wires are housed in the recess 44 of the frame 40. That is, the power supply 4, the hooking metal fitting 5, the conductive wires, and other components are housed in the recess 44 of the frame 40 and in the recess 2a of the fixture body 2. The recess 44 of the frame 40 may also house a function expansion module. The function expansion module is a component constituting the LED lighting device 3, and may be, for example, various sensors such as a motion sensor or a brightness sensor, a receiving unit (light receiving unit) such as a wireless receiving unit for receiving wireless dimming signals or an infrared receiving unit for receiving infrared remote control signals, or a functional component such as a display monitor. The conductive wires and / or the function expansion module may be disposed in the space inside the inclined plate portion 42a of the first side plate portion 421 of the frame 40.

[0074] 3, the power supply device 4 housed in the recess 44 of the frame 40 is disposed on the side of the main plate portion 41 of the frame 40 opposite the side on which the board 10 is disposed. In this embodiment, the power supply device 4 is disposed close to the second side plate portion 422. In other words, the power supply device 4 is disposed close to the second side plate portion 422, which is one of the first side plate portion 421 and the second side plate portion 422 and does not have an inclined plate portion.

[0075] A long cylindrical body is formed by fixing the cover member 30 and the frame 40. End caps 50 are attached to both ends of the cylindrical body formed by the cover member 30 and the frame 40 in the longitudinal direction.

[0076] In this embodiment, the end cap 50 is provided to close the open end of the cylindrical body formed by the cover member 30 and the frame 40. In other words, the end cap 50 is attached to the cylindrical body so as to cover the open end of the cylindrical body formed by the cover member 30 and the frame 40, closing the open end of the cylindrical body. This makes it possible to prevent dust, insects, etc. from entering the inside of the cylindrical body formed by the cover member 30 and the frame 40. Note that the end cap 50 may not completely close the open end of the cylindrical body formed by the cover member 30 and the frame 40, and there may be a small gap between the end cap 50 and the frame 40.

[0077] The end caps 50 are provided at both longitudinal ends of the cover member 30. In other words, the end caps 50 are cover ends provided at the ends of the cover member 30. The end caps 50 are directly or indirectly connected to the longitudinal ends of the cover member 30. For example, the end caps 50 and the cover member 30 are fixed together with an adhesive.

[0078] The end cap 50 is made of a resin material. The end cap 50 may or may not be translucent. A translucent end cap 50 is made of a transparent resin material such as polycarbonate or acrylic. The end cap 50 may be translucent and diffusive. In this case, the end cap 50 may be made of the same material as the cover member 30, or may be made of a different material from the cover member 30.

[0079] The LED lighting device 3 configured in this manner is housed in the recess 2a of the fixture body 2 and attached to the fixture body 2. Specifically, the LED lighting device 3 is attached to the fixture body 2 using a hook 5 and an elastic holding member 6 shown in Figures 4 and 5. The hook 5 and the elastic holding member 6 are fixed to a frame 40.

[0080] The hook fitting 5 is a plate member made of sheet metal. The hook fitting 5 is fixed to one end of the frame 40 in the short direction. In this embodiment, the hook fitting 5 is provided on the part of the frame 40 on the second side plate portion 422 side. As an example, the hook fitting 5 is fixed to the main plate portion 41 with a fixing member such as a screw, and extends so as to protrude outward from the second side plate portion 422 of the frame 40. The hook fitting 5 is hooked onto the fixture main body 2. In this embodiment, as shown in FIG. 2, a slit 2c is provided on the inner wall surface of the recess 2a of the fixture main body 2, and the hook fitting 5 is hooked onto this slit 2c.

[0081] The elastic holding member 6 is a spring such as a kick spring. The elastic holding member 6 is fixed to the other end of the frame 40 in the short direction. In other words, the elastic holding member 6 is fixed to the opposite side of the frame 40 from the hook fitting 5 in the width direction of the frame 40. In this embodiment, the elastic holding member 6 is provided on a portion of the frame 40 on the first side plate portion 421 side. As an example, the elastic holding member 6 is fixed to the frame 40 by a fixing fitting or the like fixed to the frame 40. The elastic holding member 6 is detachably attached to the appliance main body 2. Specifically, the elastic holding member 6 is detachably engaged with a receiving fitting 7 fixed to the appliance main body 2.

[0082] Although two each of the hooking fittings 5 ​​and the elastic holding members 6 are provided, this is not limiting. Furthermore, the hooking fittings 5 ​​and the elastic holding members 6 are provided at positions facing each other in the short-side direction of the frame 40, this is not limiting.

[0083] Here, a method for attaching the LED lighting device 3 to the fixture body 2 will be described with reference to Fig. 8. Fig. 8 is a diagram for explaining a method for attaching the LED lighting device 3 to the fixture body 2 in the LED lighting fixture 1 according to embodiment 1.

[0084] When attaching the LED lighting device 3 to the fixture body 2 installed on the ceiling 100, first, as shown in (a) of Figure 8, the LED lighting device 3 is suspended in a cantilevered state by hooking the hooking bracket 5 into the slit 2c (see Figure 2) provided in the fixture body 2, and one end of the elastic holding member 6, which is a kick spring, is engaged with the receiving bracket 7 fixed to the fixture body 2.

[0085] 8(b), the LED lighting device 3 is rotated around the hook 5 as a fulcrum while the hook 5 is pushed deep into the slit 2c, thereby pushing the LED lighting device 3 up into the recess 2a of the fixture body 2. In this embodiment, the hook 5 is disposed on the second side plate 422 side of the frame 40, so that the second side plate 422 side of the LED lighting device 3 is the rotation axis side in the short direction (X-axis direction) of the frame 40. When the LED lighting device 3 is rotated, the rotation axis is parallel to the longitudinal direction (Y-axis direction) of the LED lighting device 3.

[0086] Then, by rotating the LED illumination device 3 so that the second side plate portion 422 faces the rotation axis and pushing the LED illumination device 3 into the recess 2a of the fixture body 2, the LED illumination device 3 can be fitted into the recess 2a of the fixture body 2, as shown in (c) of Figure 8. In this way, the LED illumination device 3 can be attached to the fixture body 2.

[0087] Next, the effects of the LED lighting device 3 and the LED lighting fixture 1 according to this embodiment will be described using Fig. 9 and Fig. 10, while also referring to Fig. 8. Fig. 9 is a diagram for explaining a method for attaching the LED lighting device 3X to the fixture body 2 in the LED lighting fixture 1X of Comparative Example 1. Fig. 10 is a diagram for explaining a method for attaching the LED lighting device 3X to the fixture body 2 in the LED lighting fixture 1Y of Comparative Example 2.

[0088] 9(a), in the LED lighting device 3X of Comparative Example 1, the pair of mounting portions 32X of the cover member 30X extend perpendicular to the main plate portion 41 of the frame 40X, and the pair of side plate portions 42X of the frame 40X extend perpendicular to the main plate portion 41. In other words, both side surfaces of the frame 40X are straight, and the pair of side plate portions 42X extend parallel to the inner surfaces of the recessed portion 2a of the fixture body 2. Furthermore, in the LED lighting device 3X of Comparative Example 1, the pair of mounting portions 32X of the cover member 30X have the same length, and the pair of side plate portions 42X of the frame 40X have the same length.

[0089] When attaching the LED lighting device 3X having such a configuration to the fixture body 2 installed on the ceiling 100, as in the present embodiment, the hooking metal fitting 5 is hooked onto the slit 2c formed in the fixture body 2, and the LED lighting device 3X is rotated around the hooking metal fitting 5 as a fulcrum while pushing the hooking metal fitting 5 deep into the slit 2c. At this time, if the hooking metal fitting 5 is not pushed deep enough into the slit 2c, the mounting portion 32X of the cover member 30X may come into contact with and get caught on a part of the fixture body 2, as shown in Fig. 9(b).

[0090] Furthermore, because the frame 40X and the fixture body 2 are made of sheet metal, they may be warped. For example, the frame 40X has an inward curvature at the center of its longitudinal direction, which convexly faces inward. Furthermore, because the fixture body 2 is attached to the ceiling 100 with bolts, tightening the bolts may cause the frame 40X to have an inward curvature at the center of its longitudinal direction, or cause the fixture body 2 to warp so that the opening of the recess 2a narrows in the XZ cross section. Therefore, if the amount of warping of the frame 40X and the fixture body 2 becomes large, the mounting portion 32X of the cover member 30X may come into contact with and become caught on a part of the fixture body 2 when the LED lighting device 3X is rotated to attach the LED lighting device 3X to the fixture body 2.

[0091] In this way, if the mounting portion 32X of the cover member 30X hits and gets caught on a part of the fixture body 2, the LED lighting device 3X may not be able to be smoothly attached to the recess 2a of the fixture body 2. Furthermore, even if the LED lighting device 3X can be attached to the fixture body 2, the LED lighting device 3X may hit the fixture body 2, which may result in scratches on the LED lighting device 3X or the fixture body 2.

[0092] 10(a), instead of rotating the LED lighting device 3X, the LED lighting device 3X may be pulled straight up vertically to fit into the recess 2a of the fixture body 2. Even in this case, as shown in FIG. 10(b), if the LED lighting device 3X is slightly tilted, the mounting portion 32X of the cover member 30X may come into contact with a part of the fixture body 2, making it impossible to smoothly mount the LED lighting device 3X into the recess 2a of the fixture body 2.

[0093] As described above, the configuration of the conventional LED lighting device 3X has a problem in that the workability when attaching the LED lighting device 3X to the fixture body 2 is poor.

[0094] In contrast, in the LED lighting device 3 and the LED lighting fixture 1 according to this embodiment, the frame 40 has an elongated main plate portion 41 to which the substrate 10 is attached, and a pair of side plate portions 42 protruding from each of both ends of the main plate portion 41 in the short direction toward the opposite side to the LEDs 20, and at least one of the pair of side plate portions 42 has an inclined plate portion 42a that inclines so as to approach the other of the pair of side plate portions 42 as it moves away from the main plate portion 41. Similarly, in the cover member 30, at least one of the pair of mounting portions 32 has an inclined plate portion 32a that inclines so as to approach the other of the pair of mounting portions 32 as it moves away from the cover body portion 31.

[0095] As a result, the tip portions of the cover member 30 and the frame 40 facing the fixture body 2 are configured to tilt inward, making it less likely that a part of the LED lighting device 3 (the cover member 30 or the frame 40, etc.) will come into contact with the fixture body 2 when attaching the LED lighting device 3 to the fixture body 2. Furthermore, the inclined plate portion 42a of the frame 40 and / or the inclined plate portion 32a of the cover member 30 function as a guide when attaching the LED lighting device 3 to the fixture body 2. This allows the worker installing the LED lighting fixture 1 to easily fit the LED lighting device 3 into the recess 2a of the fixture body 2. As such, the LED lighting device 3 according to this embodiment can improve the ease of installation when attaching the LED lighting device 3 to the fixture body 2.

[0096] In particular, as shown in Figure 8, when rotating the LED lighting device 3 to attach it to the fixture body 2, it is preferable to rotate the LED lighting device 3 and attach it to the fixture body 2 so that the first side plate portion 421 side having the inclined plate portion 42a is opposite to the rotation axis side and the second side plate portion 422 side not having the inclined plate portion is on the rotation axis side.

[0097] 8(b), when the LED lighting device 3 is rotated around the hooking metal fitting 5 hooked on the slit 2c of the fixture body 2 as a fulcrum, the portion of the frame 40 on the first side plate portion 421 side and the portion of the cover member 30 on the first mounting portion 321 side become the outer circumference of the rotation. At this time, in this embodiment, since the first side plate portion 421 has the inclined plate portion 42a and the first mounting portion 321 has the inclined plate portion 32a, the first side plate portion 421 or the first mounting portion 321 is less likely to hit the fixture body 2.

[0098] Furthermore, when the LED lighting device 3 is rotated and attached to the fixture body 2 as in this embodiment, the power supply unit 4, which is located on the opposite side of the main plate portion 41 of the frame 40 from the substrate 10, should be positioned closer to the rotation axis. Specifically, the power supply unit 4 should be positioned closer to the second side plate portion 422.

[0099] In this way, by placing the heavy power supply unit 4 closer to the rotation axis, it is possible to rotate the LED lighting device 3 with less force than when the power supply unit 4 is placed on the opposite side of the rotation axis. This makes it easier to attach the LED lighting device 3 to the fixture body 2. Therefore, it is possible to further improve the ease of installation when attaching the LED lighting device 3 to the fixture body 2.

[0100] It is also advisable to position components such as the hook 5 or the function expansion module, which are taller than the legs of the side plate 42 of the frame 40, closer to the second side plate 422 (rotation axis side) in the same manner as the power supply device 4. In this case, too, the installation of the LED lighting device 3 to the fixture body 2 can be easily performed.

[0101] Furthermore, by providing the inclined plate portion 42a on the first side plate portion 421 of the frame 40 located inside the inclined plate portion 32a of the cover member 30, the power supply device 4 and metal fittings such as the hook metal fitting 5 are less likely to come off.

[0102] Furthermore, the space inside the inclined plate portion 42a of the first side plate portion 421 of the frame 40 may accommodate conductive wires and the like routed through the recessed portion 44 of the frame 40. This prevents conductive wires, such as the power line (not shown) connected to the power terminal block 8, from being pinched between a part of the LED lighting device 3 (for example, the mounting portion 32 of the cover member 30) and the fixture body 2 when the LED lighting device 3 is attached to the fixture body 2. In other words, it is possible to prevent the conductive wires from getting caught.

[0103] In this embodiment, as shown in FIG. 8, the LED lighting device 3 is rotated and attached to the fixture body 2, but this is not limiting. For example, as in the LED lighting device 3X in FIG. 10, the LED lighting device 3 may be attached to the fixture body 2 without rotating the LED lighting device 3. Specifically, the LED lighting device 3 may be pulled straight up vertically by a leaf spring (not shown) or the like to translate the LED lighting device 3 toward the fixture body 2 installed on the ceiling, and then the LED lighting device 3 may be pushed into the recess 2a of the fixture body 2 to fit it. In this way, the LED lighting device 3 can be attached to the fixture body 2 without rotating it. Note that attaching the LED lighting device 3 to the fixture body 2 without rotating it can also be applied to the following embodiments. That is, in the following embodiments, the LED lighting device may be attached to the fixture body 2 by rotating it or without rotating it.

[0104] (Embodiment 2) Next, a second embodiment will be described with reference to Fig. 11. Fig. 11 is a cross-sectional view of an LED lighting fixture 1A and an LED lighting device 3A according to the second embodiment.

[0105] An LED lighting fixture 1A and an LED lighting device 3A according to this embodiment differ from the LED lighting fixture 1 and the LED lighting device 3 according to the first embodiment in the configurations of a cover member 30A and a frame 40A.

[0106] Specifically, in the LED lighting device 3 according to the above-mentioned embodiment 1, the second mounting portion 322 of the cover member 30 does not have an inclined plate portion and is not bent in the middle, but in the LED lighting device 3A according to this embodiment, the second mounting portion 322A of the cover member 30A has an inclined plate portion 32a and an orthogonal plate portion 32b, similar to the first mounting portion 321.

[0107] As described above, in the LED lighting device 3A of the present embodiment, one of the pair of mounting portions 32 (first mounting portion 321 in the present embodiment) has an inclined plate portion 32a that is inclined so as to approach the other mounting portion 32 (second mounting portion 322 in the present embodiment) as it moves away from the cover main body 31, and the other of the pair of mounting portions 32 has an inclined plate portion 32a that is inclined in a direction that approaches the one mounting portion 32 as it moves away from the cover main body 31. In other words, the pair of mounting portions 32 are configured so that the tip ends on the opposite side to the cover main body 31 approach each other.

[0108] In the LED lighting device 3 according to the first embodiment, the second side plate portion 422 of the frame 40 does not have an inclined plate portion and is not bent in the middle, but in the LED lighting device 3A according to the present embodiment, the second side plate portion 422A of the frame 40A has an inclined plate portion 42a and an orthogonal plate portion 42b, similar to the first side plate portion 421.

[0109] As described above, in the LED lighting device 3A of the present embodiment, one side plate 42 (first side plate 421 in this embodiment) of the pair of side plate portions 42 not only has an inclined plate portion 42a that is inclined so as to approach the other side plate portion 42 (second side plate 422A in this embodiment) as it moves away from the main plate portion 41, but also the other side plate 42 (second side plate 422A in this embodiment) of the pair of side plate portions 42 has an inclined plate portion 42a that is inclined in a direction that approaches the one side plate portion 42 (first side plate 421 in this embodiment) as it moves away from the main plate portion 41. In other words, the pair of side plate portions 42 are configured so that the tip ends on the opposite side to the main plate portion 41 approach each other, and both of the pair of side plate portions 42 are formed to lean inward.

[0110] As described above, in the LED lighting device 3A according to this embodiment, as in the LED lighting device 3 according to the first embodiment, at least one of the pair of side plate portions 42 has an inclined plate portion 42a that inclines toward the other of the pair of side plate portions 42 as it moves away from the main plate portion 41.

[0111] With this configuration, when attaching the LED lighting device 3A to the fixture body 2, it is less likely that a part of the LED lighting device 3A will come into contact with the fixture body 2. Therefore, it is possible to improve the ease of attaching the LED lighting device 3A to the fixture body 2.

[0112] In the LED lighting device 3A of this embodiment, each of the pair of side plate portions 42 of the frame 40A has an inclined plate portion 42a, and each of the pair of mounting portions 32 of the cover member 30A has an inclined plate portion 32a. Specifically, both the first side plate portion 421 and the second side plate portion 422 have an inclined plate portion 42a.

[0113] As a result, when the LED lighting device 3A is rotated to be attached to the fixture body 2, the LED lighting device 3A is less likely to hit the fixture body 2 regardless of which of the pair of side plate portions 42 is on the rotation axis side. Also, when the LED lighting device 3A is attached to the fixture body 2 without being rotated, the LED lighting device 3A is less likely to hit the fixture body 2 regardless of whether the LED lighting device 3A is tilted to the left or right. Therefore, according to the LED lighting device 3A in this embodiment, it is possible to further improve the ease of installation when attaching the LED lighting device 3A to the fixture body 2.

[0114] In the present embodiment, the first mounting portion 321 and the second mounting portion 322A of the cover member 30A are symmetrical in the XZ cross section, but this is not limitative. That is, the inclination angle of the inclined plate portion 32a of the first mounting portion 321 and the inclination angle of the inclined plate portion 32a of the second mounting portion 322A do not have to be the same, and may be different.

[0115] Similarly, the first side plate 421 and the second side plate 422A of the frame 40A are symmetrical in the XZ cross section, but this is not limitative. That is, the inclination angle of the inclined plate portion 42a of the first side plate 421 and the inclination angle of the inclined plate portion 42a of the second side plate 422A do not have to be the same, and may be different.

[0116] In this way, by adjusting the inclination angles of the inclined plate portions 32a and 42a, it is possible to realize an LED lighting device 3A that is even easier to install.

[0117] (Embodiment 3) Next, a third embodiment will be described with reference to Fig. 12. Fig. 12 is a cross-sectional view of an LED lighting fixture 1B and an LED lighting device 3B according to the third embodiment.

[0118] An LED lighting fixture 1B and an LED lighting device 3B according to this embodiment differ from the LED lighting fixture 1 and the LED lighting device 3 according to the first embodiment in the configurations of a cover member 30B and a frame 40B.

[0119] Specifically, in the LED lighting device 3 according to the first embodiment, the first mounting portion 321 of the cover member 30 has the inclined plate portion 32a and the orthogonal plate portion 32b, but in the LED lighting device 3B according to the present embodiment, the first mounting portion 321B of the cover member 30B does not have the orthogonal plate portion 32b, and has only the inclined plate portion 32a of the inclined plate portion 32a and the orthogonal plate portion 32b. Specifically, the inclined plate portion 32a of the first mounting portion 321B is connected to the extension piece 33 and is inclined from the extension piece 33.

[0120] Furthermore, in the LED lighting device 3 according to the first embodiment, the first side plate portion 421 of the frame 40 has the inclined plate portion 42a and the orthogonal plate portion 42b. However, in the LED lighting device 3B according to the present embodiment, the first side plate portion 421B of the frame 40B does not have the orthogonal plate portion 42b, and has only the inclined plate portion 42a of the inclined plate portion 42a and the orthogonal plate portion 42b. Specifically, the entire first side plate portion 421B is the inclined plate portion 42a, and the inclined plate portion 42a is connected to the main plate portion 41. In other words, the first side plate portion 421B is bent from its base on the main plate portion 41 side. Therefore, the first side plate portion 421B (inclined plate portion 42a) is inclined from the main plate portion 41, and the first side plate portion 421B (inclined plate portion 42a) and the main plate portion 41 form an acute angle, forming a V-shaped cross section.

[0121] As described above, in the LED lighting device 3B according to the present embodiment, as in the LED lighting device 3 according to the first embodiment, at least one of the pair of side plate portions 42 has an inclined plate portion 42a that inclines toward the other of the pair of side plate portions 42 as it moves away from the main plate portion 41. Specifically, the first side plate portion 421B has the inclined plate portion 42a.

[0122] With this configuration, when attaching the LED lighting device 3B to the fixture body 2, a part of the LED lighting device 3B is less likely to come into contact with the fixture body 2. Therefore, the ease of attaching the LED lighting device 3B to the fixture body 2 can be improved.

[0123] In the LED lighting device 3B of this embodiment, the first side plate portion 421B of the frame 40B does not have the orthogonal plate portion 42b, and the entire first side plate portion 421B is the inclined plate portion 42a, which is connected to the main plate portion 41. In addition, the first mounting portion 321B of the cover member 30B also does not have the orthogonal plate portion 32b.

[0124] With this configuration, the tip ends of the first side plate portion 421B of the frame 40B and the first mounting portion 321B of the cover member 30B can be positioned more inward than in the first embodiment. This makes it even less likely that a part of the LED lighting device 3B will come into contact with the fixture body 2 when attaching the LED lighting device 3B to the fixture body 2. This further improves the ease of installation when attaching the LED lighting device 3B to the fixture body 2.

[0125] (Fourth embodiment) Next, a fourth embodiment will be described with reference to Fig. 13. Fig. 13 is a cross-sectional view of an LED lighting fixture 1C and an LED lighting device 3C according to the fourth embodiment.

[0126] The LED lighting fixture 1C and the LED lighting device 3C according to this embodiment differ from the LED lighting fixture 1B and the LED lighting device 3B according to the third embodiment in the configurations of a frame 40C and a cover member 30C.

[0127] Specifically, in the LED lighting device 3B according to the third embodiment, the second mounting portion 322 of the cover member 30B does not have an inclined plate portion, but in the LED lighting device 3C according to the present embodiment, the second mounting portion 322C of the cover member 30C has an inclined plate portion 32a. Specifically, the second mounting portion 322C has an inclined plate portion 32a but does not have an orthogonal plate portion. Therefore, the inclined plate portion 32a of the second mounting portion 322C is connected to the extension piece 33 and is inclined from the extension piece 33.

[0128] The first mounting portion 321C of the cover member 30C has the same configuration as the first mounting portion 321B in the above-described embodiment 3. That is, the first mounting portion 321C has an inclined plate portion 32a but does not have an orthogonal plate portion.

[0129] As described above, in the LED lighting device 3C of the present embodiment, one of the pair of mounting portions 32 (first mounting portion 321C in this embodiment) not only has an inclined plate portion 32a that is inclined so as to approach the other mounting portion 32 (second mounting portion 322C in this embodiment) as it moves away from the cover main body 31, but also the other of the pair of mounting portions 32 (second mounting portion 322C in this embodiment) has an inclined plate portion 32a that is inclined in a direction that approaches the one mounting portion 32 (first mounting portion 321C in this embodiment) as it moves away from the cover main body 31. In other words, the pair of mounting portions 32 are configured so that the tip ends on the opposite side to the cover main body 31 approach each other.

[0130] Furthermore, in the LED lighting device 3B according to the third embodiment, the second side plate 422 of the frame 40B does not have an inclined plate portion. However, in the LED lighting device 3C according to the present embodiment, the second side plate 422C of the frame 40C has an inclined plate portion 42a. Specifically, the second side plate 422C has the inclined plate portion 42a but does not have an orthogonal plate portion. Specifically, the entire second side plate 422C is the inclined plate portion 42a, and the inclined plate portion 42a of the second side plate 422C is connected to the main plate 41. In other words, the second side plate 422C is bent from its base on the main plate 41 side, similar to the first side plate 421C. Therefore, the second side plate portion 422C (inclined plate portion 42a) is inclined from the main plate portion 41, and the second side plate portion 422C (inclined plate portion 42a) and the main plate portion 41 form an acute angle to form a V-shaped cross section.

[0131] The first side plate portion 421C of the frame 40C has the same configuration as the first side plate portion 421B in the above-described embodiment 3. That is, the first side plate portion 421C has only the inclined plate portion 42a out of the inclined plate portion 42a and the orthogonal plate portion 42b.

[0132] As described above, in the LED lighting device 3C of the present embodiment, one side plate 42 (first side plate 421C in this embodiment) of the pair of side plate portions 42 has an inclined plate portion 42a that is inclined so as to approach the other side plate portion 42 (second side plate 422C in this embodiment) as it moves away from the main plate portion 41, and the other side plate portion 42 (second side plate 422C in this embodiment) of the pair of side plate portions 42 has an inclined plate portion 42a that is inclined in a direction that approaches the one side plate portion 42 (first side plate 421C in this embodiment) as it moves away from the main plate portion 41. In other words, the pair of side plate portions 42 are configured so that the tip portions on the opposite sides to the main plate portion 41 approach each other, and both of the pair of side plate portions 42 are formed so as to lean inward from their bases.

[0133] As described above, in the LED lighting device 3C according to this embodiment, as in the LED lighting device 3 according to the first embodiment, at least one of the pair of side plate portions 42 has an inclined plate portion 42a that inclines so as to approach the other of the pair of side plate portions 42 as it moves away from the main plate portion 41.

[0134] With this configuration, when attaching the LED lighting device 3C to the fixture body 2, it is less likely that a part of the LED lighting device 3C will come into contact with the fixture body 2. Therefore, it is possible to improve the ease of attaching the LED lighting device 3C to the fixture body 2.

[0135] Furthermore, in the LED lighting device 3C of this embodiment, each of the pair of side plate portions 42 of the frame 40C has an inclined plate portion 42a, and each of the pair of mounting portions 32 of the cover member 30C has an inclined plate portion 32a.

[0136] As a result, when the LED lighting device 3C is rotated and attached to the fixture body 2, the LED lighting device 3C is less likely to hit the fixture body 2 regardless of which of the pair of side plate portions 42 is on the rotation axis side. Also, even when the LED lighting device 3C is attached to the fixture body 2 without rotating it, the LED lighting device 3C is less likely to hit the fixture body 2 regardless of whether the LED lighting device 3C is tilted to the left or right. Therefore, the LED lighting device 3C in this embodiment can further improve the ease of installation when attaching the LED lighting device 3C to the fixture body 2.

[0137] In the present embodiment, the first and second mounting portions 321C and 322C of the cover member 30C are symmetrical in the XZ cross section, but this is not limiting. That is, the inclination angle of the inclined plate portion 32a of the first mounting portion 321C and the inclination angle of the inclined plate portion 32a of the second mounting portion 322C may not be the same, but may be different.

[0138] Similarly, the first side plate portion 421C and the second side plate portion 422C of the frame 40C are symmetrical in the XZ cross section, but this is not limitative. That is, the inclination angle of the inclined plate portion 42a of the first side plate portion 421C and the inclination angle of the inclined plate portion 42a of the second side plate portion 422C do not have to be the same, and may be different.

[0139] In this way, by adjusting the inclination angles of the inclined plate portions 32a and 42a, it is possible to realize an LED lighting device 3A that is even easier to install.

[0140] (Embodiment 5) Next, a fifth embodiment will be described with reference to Fig. 14. Fig. 14 is a cross-sectional view of an LED lighting fixture 1D and an LED lighting device 3D according to the fifth embodiment.

[0141] The LED lighting fixture 1D and LED lighting device 3D according to the present embodiment are different from the LED lighting fixture 1 and LED lighting device 3 according to the above-mentioned embodiment 1 in the configuration of the frame 40D. Specifically, in the above-mentioned embodiment 1, the main plate portion 41 of the frame 40 is provided with a stepped portion 41a which is a flat portion and a recessed portion 41b. In contrast, in the present embodiment, the main plate portion 41D of the frame 40 is provided with a recessed portion 41b on which the substrate 10 is placed, but is not provided with a stepped portion 41a which is a flat portion. Therefore, the shape of the XZ cross section of the frame 40D is approximately M-shaped.

[0142] In the LED lighting device 3D of this embodiment, as in the LED lighting device 3 in the above-mentioned embodiment 1, at least one of the pair of side plate portions 42 has an inclined plate portion 42a that inclines so as to approach the other of the pair of side plate portions 42 as it moves away from the main plate portion 41.

[0143] With this configuration, when the LED lighting device 3D is attached to the fixture body 2, a part of the LED lighting device 3D is less likely to come into contact with the fixture body 2. Therefore, the ease of attachment of the LED lighting device 3D to the fixture body 2 can be improved.

[0144] Furthermore, by making the XZ cross section of the frame 40D approximately M-shaped as in the LED lighting device 3D of this embodiment, the strength of the frame 40D can be increased, a larger space can be secured for arranging the power supply device 4, and luminous flux loss in downward light distribution can be reduced.

[0145] The depth of the recess 41b of the main plate 41D of the frame 40D may be further increased. For example, the bottom of the recess 41b may be positioned at the tip of the pair of side plate portions 42. However, it is preferable that the tip of the pair of side plate portions 42 is positioned closer to the ceiling than the bottom of the recess 41b of the main plate portion 41D. Similarly, it is preferable that the tip of the pair of mounting portions 32 of the cover member 30 is positioned closer to the ceiling than the bottom of the recess 41b of the main plate portion 41D of the frame 40D. In other words, it is preferable that the tip of the pair of side plate portions 42 and the tip of the pair of mounting portions 32 protrude toward the ceiling further than the bottom of the recess 41b of the main plate portion 41D.

[0146] (Embodiment 6) Next, a sixth embodiment will be described with reference to Fig. 15. Fig. 15 is a cross-sectional view of an LED lighting fixture 1E and an LED lighting device 3E according to the sixth embodiment.

[0147] An LED lighting fixture 1E and an LED lighting device 3E according to this embodiment differ from the LED lighting fixture 1 and the LED lighting device 3 according to the first embodiment in the configurations of a cover member 30E and a frame 40E.

[0148] Specifically, in this embodiment, the main board 41E of the frame 40E has a recessed portion 41c. The recessed portion 41c has a concave shape on the surface of the main board 41E facing the light-emitting surface of the LED 20. Specifically, the recessed portion 41c is formed by recessing a portion of the main board 41E toward the ceiling. In this case, the recessed portion 41c can be formed, for example, by pressing a portion of the main board 41E so that it recesses toward the ceiling. Therefore, the thickness of the bottom of the recessed portion 41c is the same as the thickness of the portion of the main board 41E where the recessed portion 41c is not formed.

[0149] The recessed portions 41c are provided at the ends of the main plate portion 41E in the short-side direction (X-axis direction). In this embodiment, the recessed portions 41c are provided at both ends of the main plate portion 41E in the short-side direction. Specifically, each recessed portion 41c is formed at the connection portion between the main plate portion 41E and the side plate portion 42 so as to eliminate corners between the main plate portion 41E and the side plate portion 42. The recessed portions 41c are provided along the longitudinal direction (Y-axis direction) of the main plate portion 41E. In this embodiment, the recessed portions 41c are provided over the entire length of the main plate portion 41E in the long-side direction.

[0150] In the present embodiment, the extension piece 33E of the cover member 30E is located in the recessed portion 41c of the frame 40E. Specifically, the extension piece 33E extends from the attachment portion 32 of the cover member 30E along the short-side direction (X-axis direction) of the cover member 30E.

[0151] Further, the extension piece 33E is accommodated in the recessed portion 41c so as not to protrude from the recessed portion 41c. In other words, the extension piece 33E is located at a position set back from the light-emitting surface of the LED 20 and does not protrude beyond the light-emitting surface of the LED 20 toward the floor. Therefore, unlike the extension piece 33 in the first embodiment, the extension piece 33E in this embodiment does not have a step portion and is flat.

[0152] In the LED lighting device 3E of this embodiment, as in the LED lighting device 3 of the above-mentioned embodiment 1, at least one of the pair of side plate portions 42 has an inclined plate portion 42a that inclines so as to approach the other of the pair of side plate portions 42 as it moves away from the main plate portion 41.

[0153] With this configuration, when the LED lighting device 3E is attached to the fixture body 2, a part of the LED lighting device 3E is less likely to come into contact with the fixture body 2. Therefore, the ease of attachment of the LED lighting device 3E to the fixture body 2 can be improved.

[0154] Furthermore, in the LED lighting device 3E according to this embodiment, a recessed portion 41c is provided in the main plate portion 41E of the frame 40E, and the extension piece 33E of the cover member 30E is located in the recessed portion 41c.

[0155] This configuration prevents light emitted from the LEDs 20 from reaching the extension piece 33E. As a result, the light from the LEDs 20 is not blocked by the extension piece 33E, and therefore, the occurrence of a difference in brightness on the light-emitting surface at the end of the short side of the cover member 30E can be prevented. Therefore, the end of the LED lighting device 3E in the short side direction (X-axis direction) can be illuminated clearly.

[0156] Furthermore, since the light from the LEDs 20 does not reach the extension piece 33E, the light from the LEDs 20 does not enter the extension piece 33E. This prevents the light from the LEDs 20 from being guided through the extension piece 33E and the mounting portion 32 and leaking from the end of the mounting portion 32, etc. Therefore, it is possible to obtain a desired light distribution and a desired lighting atmosphere.

[0157] (Embodiment 7) Next, the seventh embodiment will be described with reference to Fig. 16. Fig. 16 is a cross-sectional view of an LED lighting fixture 1F and an LED lighting device 3F according to the seventh embodiment.

[0158] An LED lighting fixture 1F and an LED lighting device 3F according to this embodiment differ from the LED lighting fixture 1 and the LED lighting device 3 according to the first embodiment in the configurations of a cover member 30F and a frame 40F.

[0159] In the present embodiment, one of the pair of mounting portions 32 of the cover member 30F has an extending piece 32d (cover member extending piece) in addition to the inclined plate portion 32a and the orthogonal plate portion 32b. This extending piece 32d is connected to the end of the inclined plate portion 32a opposite to the orthogonal plate portion 32b side, and extends in a direction approaching the other mounting portion 32. Specifically, the first mounting portion 321F has the extending piece 32d, and the extending piece 32d extends from the end of the inclined plate portion 32a in a direction approaching the second mounting portion 322. The extending piece 32d is a plate-like member extending parallel to the X-axis.

[0160] Furthermore, in the present embodiment, one of the pair of side plate portions 42 of the frame 40F has an extending piece portion 42d (frame extending piece portion) in addition to the inclined plate portion 42a. This extending piece portion 42d is connected to the end of the inclined plate portion 42a on the side opposite to the main plate portion 41 side (i.e., the orthogonal plate portion 42b side) and extends in a direction away from the other side plate portion 42. Specifically, the first side plate portion 421F has the extending piece portion 42d, and the extending piece portion 42d extends in a direction away from the second side plate portion 422. The extending piece portion 42d is a plate-like member extending parallel to the X-axis. Note that in the present embodiment, the first side plate portion 421F does not have the orthogonal plate portion 42b, and therefore the first side plate portion 421F has a Z-shape in the XZ cross section.

[0161] A predetermined space S is formed between the inclined plate portion 42a of the first side plate portion 421F of the frame 40F and the inclined plate portion 42a and the orthogonal plate portion 42b of the first mounting portion 321F of the cover member 30F. In other words, the space S is formed outside the first side plate portion 421F. The conductive wire 60 is arranged in this space S. Note that components of the LED lighting device 3F other than the conductive wire 60 may also be arranged in this space S.

[0162] Furthermore, the extending piece 42d of the first side plate 421F of the frame 40F is located on the main plate 41 side (inner side) of the extending piece 32d of the first mounting portion 321F of the cover member 30F. Note that the extending piece 42d of the first side plate 421F is close to the extending piece 42d of the first side plate 421F, but this is not limiting.

[0163] In the LED lighting device 3F of this embodiment, as in the LED lighting device 3 in the above-mentioned embodiment 1, at least one of the pair of side plate portions 42 has an inclined plate portion 42a that inclines so as to approach the other of the pair of side plate portions 42 as it moves away from the main plate portion 41.

[0164] With this configuration, when attaching the LED lighting device 3F to the fixture body 2, it is less likely that a part of the LED lighting device 3F will come into contact with the fixture body 2. Therefore, it is possible to improve the ease of installation when attaching the LED lighting device 3F to the fixture body 2.

[0165] In addition, in the LED lighting device 3F of this embodiment, one of the side plate portions 42 of the frame 40F has an extending piece portion 42d extending in a direction away from the other side plate portion 42 at the end of the inclined plate portion 42a opposite to the main plate portion 41 side.

[0166] With this configuration, a space S can be formed outside the inclined plate portion 42a of one of the side plate portions 42. As a result, components constituting the LED lighting device 3F can be arranged in this space S. For example, as in this embodiment, a conductive wire 60 such as a power line can be stored in the space S. This makes it possible to prevent the conductive wire 60 from being pinched between a part of the LED lighting device 3 (for example, the mounting portion 32 of the cover member 30F) and the fixture body 2 when the LED lighting device 3 is attached to the fixture body 2. In other words, it is possible to prevent the conductive wire 60 from being caught.

[0167] (Embodiment 8) Next, the eighth embodiment will be described with reference to Fig. 17. Fig. 17 is a cross-sectional view of an LED lighting device 3G used in an LED lighting fixture according to the eighth embodiment.

[0168] An LED lighting device 3G according to this embodiment differs from the LED lighting device 3 according to the first embodiment in the configuration of a frame 40G.

[0169] Specifically, in the first embodiment, recesses 41b are formed in main plate 41 of frame 40, but in the present embodiment, recesses 41b are not formed in main plate 41G of frame 40G. Therefore, main plate 41G is a flat plate.

[0170] In the LED lighting device 3G of this embodiment, as in the LED lighting device 3 in the above-mentioned embodiment 1, at least one of the pair of side plate portions 42 has an inclined plate portion 42a that inclines so as to approach the other of the pair of side plate portions 42 as it moves away from the main plate portion 41.

[0171] With this configuration, when attaching the LED lighting device 3G to the fixture body 2, a part of the LED lighting device 3G is less likely to come into contact with the fixture body 2. Therefore, the ease of attaching the LED lighting device 3G to the fixture body 2 can be improved.

[0172] In addition, in this embodiment, the recessed portion 41b is not formed in the main plate portion 41G of the frame 40G, and the shape of the frame 40G is simplified.

[0173] This configuration makes it possible to manufacture frame 40G more easily than frame 40 in the first embodiment.

[0174] (Other variations) The LED lighting fixture and LED lighting device according to the present invention have been described above based on the first to eighth embodiments, but the present invention is not limited to these first to eighth embodiments.

[0175] For example, in the above-described first embodiment and the like, the entire substrate 10 contacts the metal portion of the main plate 41 of the frame 40. However, this is not limited to this. Specifically, as shown in an LED lighting device 3H shown in FIG. 18 , an opening 41e may be formed in the main plate 41H of the frame 40H, and a portion of the second surface 10b of the substrate 10 may be exposed through the opening 41e of the frame 40H. In this case, instead of contacting the second surface 10b of the substrate 10 with the outer surface of the main plate 41H of the frame 40H, the first surface 10a of the substrate 10 may contact the inner surface of the main plate 41H of the frame 40H, as in an LED lighting device 3I shown in FIG. 19 . In other words, the substrate 10 may be disposed inside the frame 40H rather than outside it. Furthermore, when the substrate 10 is disposed inside the frame 40H, a separate support member 70 for supporting the substrate 10 may be disposed, as in an LED lighting device 3J shown in FIG. 20 . The frame 40H having the main plate portion 41H with the openings 41e formed therein may have the configuration shown in Fig. 21. In the frame 40H shown in Fig. 21, three openings 41e are formed in the main plate portion 41H, but this is not limiting. The frame 40H may also be formed of two separate parts, left and right.

[0176] 22, the frame 40K may further include a support member 45 for supporting the substrate 10. The support member 45 supports the substrate 10 by pressing down on both ends of the substrate 10 in the short side direction from above.

[0177] Furthermore, the method of supporting the substrate 10 may be a method of supporting the substrate 10 by clamping both end portions of the substrate 10, as in an LED lighting device 3L shown in Fig. 23. In this case, as shown in Fig. 23, a main plate portion 41L of a frame 40L has clamping portions 41d that clamp the end portions of the substrate 10.

[0178] Furthermore, in the above-described first embodiment and the like, the substrate 10 is fixed to the frame 40 by the claws 43 provided on the main plate 41 of the frame 40, but this is not limited thereto. For example, as in an LED lighting device 3M shown in FIG. 24, the substrate 10 and the main plate 41G of the frame 40G may be fixed with an adhesive 80. The adhesive 80 is inserted between the substrate 10 and the main plate 41G. Note that although the frame 40G shown in FIG. 17 is used in this modification, the frame 40 in the above-described embodiment may also be used.

[0179] Furthermore, in the above-described first embodiment and the like, an SMD-type LED element in which an LED chip is mounted in a package is used as the LED 20, and the light-emitting module consisting of the substrate 10 and the LED 20 is an SMD-type LED module, but this is not limiting. For example, the light-emitting module consisting of the substrate 10 and the LED 20 may be a COB (Chip On Board) type LED module. In this case, LED chips (bare chips) themselves may be used as the LED 20, and multiple LEDs 20 (LED chips) may be linearly arranged on the substrate 10, and the multiple LEDs 20 may be collectively or individually sealed with a sealing member (for example, a phosphor-containing resin).

[0180] Furthermore, in the above-described first embodiment and the like, the cover member 30 having both diffusive and translucent properties is used, but this is not limiting. For example, a translucent cover having only translucent properties out of the diffusive and translucent properties may be used instead of the cover member 30. In this case, a transparent cover with high transmittance that allows the viewer to see through to the other side may be used as the translucent cover.

[0181] In addition, the present invention also includes forms obtained by applying various modifications to the above-mentioned embodiments that a person skilled in the art may conceive, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope of the present invention.
