As shown in FIGS. 3, 6 and 7, the LED lighting device 3 includes a substrate 10, LEDs 20 arranged on the substrate 10, a cover member 30 covering the LEDs 20, a frame 40 supporting the substrate 10, an end and a cap 50 .

The substrate 10 is a mounting substrate for mounting the LEDs 20 thereon. In this embodiment, the substrate 10 is formed in a substantially rectangular shape 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 equal to the 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 .

As shown in FIGS. 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 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 10 b 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. As shown in FIG.

The board 10 is, for example, a printed wiring board (printed board) on which metal wiring is formed in a predetermined pattern. In addition, 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 a double-sided wiring substrate in which wiring is formed on each of the first surface 10a and the second surface 10b. may be

The base material constituting the substrate 10 includes a resin substrate made of an insulating resin material, a ceramic substrate made of a sintered body of a ceramic material such as alumina, and a metal substrate made of a metal material such as aluminum or copper. A metal base substrate or the like obtained by applying is used.

When the substrate 10 is made of a resin substrate, the resin substrate may be, for example, a glass epoxy substrate (CEM-3, FR-4, etc.) made of glass fiber and epoxy resin, or made of kraft paper or the like and phenol resin. A paper phenol base material (FR-1, FR-2), a paper epoxy base material (FR-3) composed of paper and epoxy resin, or a polyimide substrate made of polyimide or the like can be used. Further, the substrate 10 may be a rigid substrate or a film-like flexible substrate.

As shown in FIGS. 6 and 7, a plurality of LEDs 20 are mounted on the first surface 10a of the substrate 10. FIG. In this embodiment, the plurality of LEDs 20 are mounted linearly in a 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. In addition, along the longitudinal direction of the board|substrate 10, several LED20 may be mounted not in one row but in multiple rows.

LED20 is an example of a light emitting element. In the present embodiment, each of the plurality of LEDs 20 is an individually packaged SMD structure LED element (LED light source). In this case, each LED 20 includes a resin or ceramic white container (package), an LED chip (bare chip) arranged 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 energized is used as the LED chip, and a silicone resin containing a yellow phosphor such as YAG (fluorescent body containing resin) is used.

A plurality of LEDs 20 are covered with a cover member 30 . Specifically, all the LEDs 20 are covered with the cover member 30 . The cover member 30 is an example of a translucent cover having translucency, and transmits light emitted from the LEDs 20 . In the present embodiment, the cover member 30 is a diffusion cover that not only has translucency but also has diffusibility. Therefore, the light from the LEDs 20 incident on the cover member 30 is diffused (scattered) by the cover member 30 and passes through the cover member 30 .

As shown in FIGS. 3 and 6, the cover member 30 covers the substrate 10. As shown in FIG. Specifically, the cover member 30 is arranged to face the first surface 10a of the substrate 10 so as to cover the plurality of LEDs 20 .

In this embodiment, the cover member 30 covers the entire substrate 10 on which the LEDs 20 are arranged. As shown in FIGS. 5 and 6, the cover member 30 further covers the entire frame 40 on which the substrate 10 is arranged. Therefore, the cover member 30 is elongated in the Y-axis direction, like the substrate 10 and the frame 40 .

The cover member 30 is attached to the frame 40 . A cylinder is formed by the cover member 30 and the frame 40, and the substrate 10 and the plurality of LEDs 20 mounted on the substrate 10 are housed in this cylinder.

The cover member 30 is attached to the frame 40 so as to cover the board 10 and the LEDs 20 . As shown in FIGS. 3 and 6 , the cover member 30 has a cover body portion 31 , a mounting portion 32 connected to the cover body portion 31 , and an extension piece 33 connected to the mounting portion 32 .

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 body portion 31 has, for example, a flat, substantially semi-cylindrical shape. Therefore, the cover body portion 31 has an elongated rectangular opening end surface extending in the Y-axis direction. Further, the cross-sectional shape of the cover main body portion 31 when cut along the X-axis direction has a curved shape curved in a substantially circular arc shape.

As shown in FIGS. 3 and 6 , the cover main body 31 includes a protruding portion 31 a that protrudes outward in the width direction of the cover main body 31 from the mounting portion 32 . The projecting portions 31 a are formed at both ends of the cover body portion 31 in the short direction (width direction). Each projecting portion 31a has a recessed portion 31a1 that is recessed on the side opposite to the frame 40 side. If the concave portion 31a1 is formed, dead insects and foreign substances may accumulate in the concave portion 31a1, and the ends of the cover main body portion 31 in the short direction may not shine cleanly. Therefore, it is not necessary to form the concave portion 31a1 in each protruding portion 31a. In this case, for example, the shape of the XZ cross section of the protruding portion 31a is V-shaped, and the ceiling side portion of the protruding portion 31a is formed so as to form the same plane as the extension piece 33 via the mounting portion 32. good too.

The attachment portion 32 is a portion attached to the frame 40 . Specifically, the attachment portion 32 is attached to the side plate portion 42 of the frame 40 . Further, the mounting portion 32 is an extension portion extending from the cover body portion 31 toward the frame 40 side.

A pair of mounting portions 32 are provided on the cover body portion 31 . Specifically, the mounting portions 32 are formed as a pair of legs so as to stand on the cover body portion 31 from both ends of the cover body portion 31 in the short direction (X-axis direction). Therefore, the pair of mounting portions 32 protrude from the cover body portion 31 toward the ceiling. In addition, as shown in FIG. 7, each of the pair of mounting portions 32 is elongated along the Y-axis direction. The lengths of the pair of mounting portions 32 in the Y-axis direction are the same.

As shown in FIGS. 3, 6 and 7, at least one mounting portion 32 of the pair of mounting portions 32 has an inclined plate portion 32a (cover inclined plate portion). The inclined plate portion 32 a is inclined so as to approach the other mounting portion 32 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 configured by a first mounting portion 321 and a second mounting portion 322 provided facing each other in the X-axis direction. 32) and the second mounting portion 322 (the other mounting portion 32), only the first mounting portion 321 has the inclined plate portion 32a.

The inclined plate portion 32 a formed on the first attachment portion 321 is inclined so as to approach the second attachment portion 322 as the distance from the cover main body portion 31 increases. In other words, the inclined plate portion 32a is inclined so that the tip side thereof falls inside the frame 40. As shown in FIG. The inclined plate portion 32a is inclined at a predetermined inclination angle with respect to the XY plane. The angle (tilt angle) formed by the extending direction of the inclined plate portion 32a in the XZ cross section and the XY plane is an acute angle of less than 90 degrees, for example, 30 degrees or more and less than 90 degrees.

In the present embodiment, the first attachment portion 321 further has an orthogonal plate portion 32b (cover orthogonal plate portion) orthogonal to the main surface (XY plane in the present embodiment) of the main plate portion 41 of the frame 40. are doing. That is, the orthogonal plate portion 32b is not inclined with respect to the XY plane, and extends from the cover body portion 31 in a direction parallel to the Z-axis direction. The inclined plate portion 32a is connected to the end portion of the orthogonal plate portion 32b on the side opposite to the cover body portion 31 side.

The inclined plate portion 32a and the orthogonal plate portion 32b of the first attachment 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. In other words, the first attachment portion 321 has a shape that bends in the middle so that the portion of the inclined plate portion 32a falls inward. The angle formed by the inclined plate portion 32a and the orthogonal plate portion 32b in the XZ cross section is an obtuse angle of less than 180 degrees, for example, 120 degrees or more and less than 180 degrees.

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

As shown in FIGS. 6 and 7, each of the pair of mounting portions 32 has a recess 32c into which the tip portion of the side plate portion 42 of the frame 40 is fitted. In the present embodiment, the recess 32c is provided at the tip of each of the pair of mounting portions 32. As shown in FIG. Specifically, the recessed portion 32c is provided inside in the width direction (X-axis direction) of each tip portion of the pair of mounting portions 32 .

The tip portions of the pair of side plate portions 42 of the frame 40 are fitted into the concave portion 32c. Specifically, the tip of the first side plate portion 421 is fitted into the recess 32c of the first attachment portion 321, and the tip of the second side plate portion 422 is provided in the recess 32c of the second attachment portion 322. The bent portion 42c is fitted. In this manner, 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 with each other by fitting the tip portions of the pair of side plate portions 42 into the recesses 32c of the pair of mounting portions 32. stopped and fixed. In this embodiment, each of the pair of mounting portions 32 of the cover member 30 is positioned 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 are fixed and held by the frame 40 so as to embrace the frame 40 .

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 mounting portion 32 along the lateral direction (X-axis direction) of the cover member 30 and contacts the stepped portion 41 a of the main plate portion 41 . Therefore, the extension piece 33 is located inside the mounting portion 32 . Specifically, the extension piece 33 extends in a direction parallel to the first surface 10 a and the second surface 10 b of the substrate 10 . As an example, the extension piece 33 is a plate piece having a uniform thickness. Although the extension piece 33 is formed with a stepped portion, the stepped portion may not be formed.

The extension piece 33 functions as a stopper that presses the main plate portion 41 of the frame 40 . That is, the extension piece 33 prevents the frame 40 from shifting toward the light emitting side (floor side) of the LED 20 . In this embodiment, the extension piece 33 presses the stepped portion 41a of the main plate portion 41 from the floor side (the light emission side of the LED 20) toward the ceiling side, thereby preventing the frame 40 from slipping toward the floor side. there is

The extension piece 33 also has a function of preventing insects from entering the space between the cover main body portion 31 of the cover member 30 and the main plate portion 41 of the frame 40 . That is, by providing the extension piece 33 so as to press down the main plate portion 41, a labyrinth structure is formed in the path when an insect enters from the gap between the mounting portion 32 of the cover member 30 and the side plate portion 42 of the frame 40. Since it can be formed, it is possible to suppress the invasion of insects inside.

Further, the extension piece 33 is erected 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 length of the pair of extension pieces 33 in the X-axis direction is the same. In addition, as shown in FIG. 7, each of the pair of extension pieces 33 is elongated along the Y-axis direction. The lengths in the Y-axis direction of the pair of extension pieces 33 are also the same. As an example, the pair of extension pieces 33 have the same shape and the same shape, but this is not restrictive. Also, the pair of extension pieces 33 are provided at the same height position in the Z-axis direction.

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

The cover member 30 is formed by forming a milky-white light diffusion film containing a light diffusion material on the surface (inner surface or outer surface) of the transparent cover instead of dispersing the light diffusion material inside. good too. Further, the cover member 30 may be configured to have light diffusibility by performing diffusion processing instead of using a light diffusion material. For example, the cover member 30 may be subjected to surface treatment such as embossing to form fine irregularities on the surface of the transparent cover, or may be printed with a dot pattern on the surface of the transparent cover so as to have light diffusion properties. may be configured. Even when the cover member 30 is processed for diffusion, it may further contain a light diffusing material in order to enhance the light diffusibility.

In the present embodiment, the cover main body portion 31, the mounting portion 32, and the extension piece 33 that constitute the cover member 30 are integrally formed. Therefore, the cover body portion 31, the mounting portion 32 and the extension piece 33 are made of the same material.

The frame 40 is an elongated 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 .

As an example, the frame 40 is a sheet metal frame. The frame 40 is formed into a predetermined shape by subjecting a sheet metal (metal plate) made of, for example, SPCC (Steel Plate Cold Commercial) to roll forming or press working. In the present 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. The frame 40 is elongated in the Y-axis direction, like the substrate 10 and the instrument body 2 . The thickness of the metal plate forming frame 40 is, for example, 0.2 mm to 2 mm, and is 0.5 mm in this embodiment.

As shown in FIGS. 3 to 7, the frame 40 has a plate-like main plate portion 41 and a pair of plate-like 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.

The main plate portion 41 is the body portion of the frame 40 . The main plate portion 41 has a pair of stepped portions 41a extending in the width direction (X-axis direction) along the longitudinal direction. The stepped portion 41a is a flat portion. Further, by forming the pair of stepped portions 41a, the main plate portion 41 is formed with a recessed portion 41b. The pair of stepped portion 41a and recessed portion 41b are formed over the entire length of the main plate portion 41 in the longitudinal direction.

As shown in FIGS. 3 and 6 , the substrate 10 is attached to the main plate portion 41 . Specifically, the substrate 10 is placed on the recess 41 b of the main plate portion 41 . That is, the main plate portion 41 supports the substrate 10 . In this embodiment, the substrate 10 and the main plate portion 41 are in contact with each other.

Further, the main plate portion 41 is provided with a through hole through which a conductive wire for electrically connecting the wiring of the substrate 10 and the power supply device 4 is inserted.

A pair of side plate portions 42 constitute side portions of the frame 40 . The pair of side plate portions 42 protrude from both ends of the main plate portion 41 in the short direction (X-axis direction) to the opposite side (ceiling side) of the LED 20 side. That is, the pair of side plate portions 42 are formed as a pair of leg portions so as to stand on the main plate portion 41 .

FIG.

When attaching the LED lighting device 3 to the fixture body 2 installed on the ceiling 100, first, as shown in FIG. By hooking, the LED lighting device 3 is suspended in a cantilevered state, and one end of the elastic holding member 6 which is a kick spring is engaged with the receiving metal fitting 7 fixed to the fixture main body 2 .

Next, as shown in FIG. 8(b), the LED lighting device 3 is rotated around the hooking metal fitting 5 as a fulcrum while pushing the hooking metal fitting 5 into the back of the slit 2c. It is pushed up into the concave portion 2a. At this time, in the present embodiment, since the hooking metal fittings 5 are arranged on the second side plate portion 422 side of the frame 40, the LED lighting device 3 is positioned on the second side plate in the lateral direction (X-axis direction) of the frame 40. The part 422 side is the rotating shaft side. In addition, 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 .

Then, by rotating the LED lighting device 3 so that the second side plate portion 422 side is on the rotation shaft side and pushing the LED lighting device 3 into the concave portion 2a of the fixture body 2, as shown in FIG. The LED lighting device 3 can be fitted into the concave portion 2a of the fixture body 2. As shown in FIG. Thereby, the LED lighting device 3 can be attached to the fixture main body 2 .

Next, the effects of the LED lighting device 3 and the LED lighting fixture 1 according to the present embodiment will be described with reference to FIGS. 9 and 10 while referring to FIG. 9A and 9B are diagrams for explaining a mounting method for mounting the LED lighting device 3X to the fixture body 2 in the LED lighting fixture 1X of Comparative Example 1. FIG. 10A and 10B are diagrams for explaining a mounting method for mounting the LED lighting device 3X to the fixture main body 2 in the LED lighting fixture 1Y of Comparative Example 2. FIG.

As shown in FIG. 9A, in the LED lighting device 3X of Comparative Example 1, the pair of mounting portions 32X of the cover member 30X extend perpendicularly to the main plate portion 41 of the frame 40X, and the frame A pair of side plate portions 42X at 40X extend perpendicularly to the main plate portion 41 . That is, both side surfaces of the frame 40X are straight, and the pair of side plate portions 42X extend parallel to the inner surface of the concave portion 2a of the instrument main body 2. As shown in FIG. Further, in the LED lighting device 3X of Comparative Example 1, the length of the pair of mounting portions 32X of the cover member 30X is the same, and the length of the pair of side plate portions 42X of the frame 40X is the same. there is

When the LED lighting device 3X having such a configuration is attached to the fixture body 2 installed on the ceiling 100, the hooking fixture 5 is hooked to the slit 2c formed in the fixture body 2 in the same manner as in the present embodiment. 5 is pushed deep into the slit 2c, and the LED lighting device 3X is rotated with the hook metal fitting 5 as a fulcrum. At this time, if the hooking metal fitting 5 is pushed into the slit 2c too little, as shown in FIG. Sometimes.

In addition, since the frame 40X and the instrument body 2 are made of sheet metal, the frame 40X and the instrument body 2 may warp. For example, the frame 40X is curved inward so that the central portion in the longitudinal direction thereof is convex inward. In addition, since the device main body 2 is installed on the ceiling 100 with bolts, tightening the bolts causes the central portion in the longitudinal direction to be warped inward so as to protrude inward, or concave in the XZ cross section. It warps so that the opening of 2a narrows. Therefore, when the amount of warp of the frame 40X and the fixture main body 2 increases, when the LED lighting device 3X is rotated to attach the LED lighting device 3X to the fixture main body 2, the mounting portion 32X of the cover member 30X may be bent into the fixture main body 2. It may hit a part of the and get caught.

In this way, if the attachment portion 32X of the cover member 30X hits a part of the fixture body 2 and is caught, the LED lighting device 3X may not be smoothly attached to the concave portion 2a of the fixture body 2 . Even if the LED lighting device 3X can be attached to the fixture body 2, the LED lighting device 3X or the fixture body 2 may be damaged because the LED lighting device 3X hits the fixture body 2.

In addition, as in the LED lighting device 1Y shown in FIG. It may be fitted into the recess 2a. Even in this case, if the LED lighting device 3X is slightly tilted as shown in FIG. In some cases, the LED lighting device 3X cannot be smoothly attached to the concave portion 2a of the fixture body 2.

As described above, the configuration of the conventional LED lighting device 3X has a problem of poor workability when attaching the LED lighting device 3X to the fixture main body 2 .

On the other hand, in the LED lighting device 3 and the LED lighting fixture 1 according to the present embodiment, the frame 40 includes a long main plate portion 41 to which the substrate 10 is attached, and both ends of the main plate portion 41 in the short direction. and a pair of side plate portions 42 protruding on the side opposite to the LED 20 side from each of the pair of side plate portions 42, and at least one side plate portion 42 of the pair of side plate portions 42 moves away from the main plate portion 41. It has an inclined plate portion 42a inclined so as to approach the other side plate portion 42 of 42 . Also, with respect to the cover member 30, at least one mounting portion 32 of the pair of mounting portions 32 inclines so as to approach the other mounting portion 32 of the pair of mounting portions 32 as the distance from the cover main body portion 31 increases.

As a result, when the LED lighting device 3 is rotated around the hook metal fitting 5 hooked on the slit 2c of the fixture body 2 as a fulcrum, as shown in FIG. and the portion of the cover member 30 on the side of the first attachment portion 321 are the outer circumferences of rotation. At this time, in the present 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 becomes less likely to hit the tool body 2.

Further, when the LED lighting device 3 is rotated and attached to the fixture main body 2 as in the present embodiment, the power supply device 4 arranged on the side opposite to the substrate 10 side of the main plate portion 41 of the frame 40 is mounted on the rotating shaft side. It is preferable that it is placed close to the Specifically, the power supply device 4 may be arranged closer to the second side plate portion 422 side.

This facilitates the work of attaching the LED lighting device 3 to the fixture main body 2 . Therefore, it is possible to further improve workability when attaching the LED lighting device 3 to the fixture main body 2 .

It should be noted that a component taller than the length of the leg of the side plate portion 42 of the frame 40, such as the hook 5 or the function expansion module, may also should be placed close to Also in this case, the work of attaching the LED lighting device 3 to the fixture main body 2 can be easily performed.

Moreover, 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, metal fittings such as the power supply device 4 and the hooking metal fitting 5 are less likely to come off.

In addition, in the space inside the inclined plate portion 42 a of the first side plate portion 421 of the frame 40 , a conductive wire or the like routed to the concave portion 44 of the frame 40 may be accommodated. As a result, when the LED lighting device 3 is attached to the fixture main body 2 , a conductive wire such as a power line (not shown) connected to the power terminal block 8 is attached to a part of the LED lighting device 3 (for example, the mounting portion of the cover member 30 ). 32) and the instrument main body 2 can be suppressed. In other words, it is possible to suppress wire biting of the conductive wires.

Moreover, in the present embodiment, as shown in FIG. 8, the LED lighting device 3 is rotated and attached to the fixture main body 2, but the present invention is not limited to this. For example, like an LED lighting device 3X in FIG. 10, the LED lighting device 3 may be attached to the fixture main body 2 without rotating the LED lighting device 3. FIG. Specifically, the LED lighting device 3 is straightly pulled up in the vertical direction by a leaf spring (not shown) or the like so as to move the LED lighting device 3 in parallel toward the fixture main body 2 installed on the ceiling. may be pushed into the concave portion 2a of the instrument body 2 and fitted. As a result, the LED lighting device 3 can be attached to the fixture main body 2 without being rotated. It should be noted that attaching the LED lighting device 3 to the fixture main body 2 without rotating it can also be applied to the following embodiments. That is, also in the following embodiments, the LED lighting device may be attached to the fixture main body 2 by rotating it, or may be attached to the fixture main body 2 without rotating it.

Specifically, the recessed portion 41c is formed by recessing a portion of the main plate portion 41E toward the ceiling. In this case, the recessed portion 41c can be formed by, for example, pressing a part of the main plate portion 41 so as to recess it so as to retreat toward the ceiling. Therefore, the plate thickness of the bottom portion of the recessed portion 41c and the plate thickness of the portion of the main plate portion 41E where the recessed portion 41c is not formed are the same.

The recessed portion 41c is provided at the end portion of the main plate portion 41E in the lateral direction (X-axis direction). In the present embodiment, the recessed portion 41c is provided at each of both ends in the short direction of the main plate portion 41E. Specifically, each recessed portion 41c is formed at a connecting portion between the main plate portion 41E and the side plate portion 42 so as to eliminate the corner portion between the main plate portion 41E and the side plate portion 42.

Therefore, the ends of the LED illumination device 3E in the lateral direction (X-axis direction) can be illuminated beautifully.

Moreover, since the light from the LED 20 does not reach the extension piece 33E, the light from the LED 20 will not enter the extension piece 33E. As a result, the light from the LED 20 is guided through the extension piece 33E and the mounting portion 32 and is prevented from leaking from the end portion of the mounting portion 32 or the like. Therefore, a desired light distribution and a desired lighting atmosphere can be obtained.
