The cover main portion 231 has a cross section in the short side direction Y that is arc-shaped and is formed so as to continue in the long side direction X.
The cover lid portion 232 is provided at the longitudinal direction X side end of the cover main portion 231. The cover lid portion 232 closes the space formed by the frame 220 and the cover main portion 231 in the longitudinal direction X, and is provided at each end of the light source unit 200 in the longitudinal direction X.

The connecting portion 240 is used to attach the light source unit 200 to the lighting fixture 100 , and is disposed so as to correspond to the mounting portion 120 of the lighting fixture 100 .
The connecting portion 240 is attached to the other surface 221b of the board holding portion 221, and is provided on each of both end sides of the light source unit 200 in the longitudinal direction X. The connecting portion 240 clamps both ends of the flat mounting portion 122 of the mounting portion 120 in the lateral direction Y, and has a connecting main body portion 241 and a connecting movable portion 242.

The connecting body 241 includes a connecting bottom surface 2411, a connecting leg 2412, and a connecting control section 2413. The connecting body 241 includes the connecting leg 2412 at one end of the connecting bottom surface 2411 in the short direction X, and the connecting control section 2413 at the other end. The connecting body 241 is formed by bending a metal plate.

The connecting bottom surface portion 2411 is formed in a rectangular shape that is longer than the length of the board holding portion 221 in the short direction Y, and is attached to the board holding portion 221. The connecting bottom surface portion 2411 has a bottom surface rising portion 2411a and a bottom surface opening portion 2411b.
The bottom surface rising portion 2411a is a plate-like portion that protrudes upward in the upward direction Z1 from a side edge along the short direction Y of the connecting bottom surface portion 2411.
The bottom opening 2411b is an opening into which the movable connecting part 242 is inserted, and is provided on the side of the connecting control part 2413. The bottom opening 2411b is provided from the connecting bottom part 2411 to the connecting control part 2413.

The connecting leg portion 2412 is provided to protrude upward in the Z1 direction from one end of the connecting bottom surface portion 2411 in the short side direction X, and has a leg protrusion portion 2412a and a leg claw portion 2412b.
The leg protrusion 2412a protrudes in a plate shape from the side of the connecting leg 2412 toward the connection control unit 2413, and is provided so as to overlap with the bottom rising portion 2411a. The leg protrusion 2412a is connected to the bottom rising portion 2411a by a fixing means such as a screw.
The leg claw portion 2412b protrudes obliquely from the end portion on the upward Z1 side of the connecting leg portion 2412 toward the connecting bottom surface portion 2411. The leg claw portion 2412b has a saw-shaped convex portion on the end portion on the downward Z2 side so as not to slip when hooked on the mounting flat portion 122.

The connection control section 2413 is provided to protrude upward in the Z1 direction from the end of the connection bottom surface section 2411 opposite the connection leg section 2412 in the short side direction X, and has a control protrusion section 2413a.
The connection control portion 2413 is formed to be shorter than the connection leg portion 2412 in the vertical direction Z. The control protrusion portion 2413a is connected to the bottom surface rising portion 2411a by a fixing means such as a screw.

The movable connecting part 242 is inserted into the bottom opening 2411b from the downward direction Z2 side and fixed to the connecting main body part 241, and has a movable bottom surface part 2421, a movable main body part 2422, and a movable claw part 2423. The movable connecting part 242 is fixed to the connecting main body part 241 so that the movable main body part 2422 abuts against the surface of the connecting leg part 2412 side of the connecting control part 2413. The movable connecting part 242 is formed by bending a plate-shaped metal having elasticity.

The movable bottom surface portion 2421 is rectangular and is fixed in contact with the surface of the main body bottom surface portion 2411 on the downward direction Z2 side.

The movable main body part 2422 is provided so as to protrude upward in the Z1 direction from the main body bottom surface part 2411. When the movable main body part 2422 is fixed to the connecting main body part 241, it protrudes upward in the Z1 direction so as to have the same length as the connecting leg part 2412.

The movable claw portion 2423 protrudes obliquely downward in the Z2 direction from the upper Z1 side end of the movable main body portion 2422. The movable claw portion 2423 protrudes so that the lower Z2 side end is at the same height as the lower Z2 side end of the leg claw portion 2412b when the movable claw portion 2423 is fixed to the connecting main body portion 241.
The movable claw portion 2423 has an end portion on the downward direction Z2 side formed into a saw-like convex portion so as not to slip when hooked onto the flat mounting portion 122.

The connecting part 240 is provided with a connecting main body part 241 and a connecting movable part 242, which are separately provided, and the connecting movable part 242 is fixed to the main body bottom surface part 2411. Therefore, when a force is applied to the movable claw part 2423 from the short side direction Y, the movable main body part 2422 can elastically deform so as to rotate in the short side direction Y around the main body bottom surface part 2411 side as an axis.
For example, in the short direction Y, when a force is applied to the movable claw portion 2423 in a direction away from the connecting leg portion 2412, the movable main body portion 2422 elastically deforms so that the movable claw portion 2423 moves in a direction away from the connecting leg portion 2412, and when the load is released, the movable claw portion 2423 returns to its original state so that it moves in a direction toward the connecting leg portion 2412.

The movable connecting part 242 is disposed so that the movable main body part 2422 abuts against the surface of the connecting leg part 2412 side of the connecting control part 2413. Therefore, when a force is applied to the movable claw part 2423 toward the outside in the short direction Y, the movable main body part 2422 can be prevented from being excessively deformed.

In addition, the connecting body 241 has the body bottom 2411 and the connecting leg 2412 connected by the bottom rising portion 2411a and the leg protrusion 2412a, and the body bottom 2411 and the connecting control unit 2413 connected by the bottom rising portion 2411a and the control protrusion 2413a, thereby improving rigidity. Unintended movement of the connecting leg 2412 and the connecting control unit 2413 in the short direction Y can be suppressed, and deformation due to load such as vibration can be suppressed.
Therefore, when light source unit 200 is attached to lighting fixture 100, it is possible to prevent light source unit 200 from falling due to vibration or the like.

The above is an explanation of the configuration of each part of the lighting fixture 100 and the light source unit 200. Next, the process of attaching the light source unit 200 to the lighting fixture 100 in order to remodel an existing lighting fixture will be explained with reference to Fig. 8. Note that the lighting fixture 100 has two attachment parts 120 in the longitudinal direction X, and the light source unit 200 has two connecting parts 240 corresponding to the attachment parts 120. Fig. 8 is a reference cross-sectional view seen from the short side direction Y, and each connecting part 240 is attached to the corresponding attachment part 120 in the longitudinal direction X by the same process.
Fig. 8 is a reference cross-sectional view showing a process of attaching the light source unit 200 to the lighting fixture 100. Fig. 8(a) shows the state before the lighting fixture 100 and the light source unit 200 are attached. Fig. 8(b) shows the state in which the connecting leg portion 2412 of the light source unit 200 is hooked to the mounting portion 120 of the lighting fixture 100. Fig. 8(c) shows the state in which the connecting movable portion 242 of the light source unit 200 is hooked to the mounting portion 120 of the lighting fixture 100 and the light source unit 200 is attached to the lighting fixture 100.

First, as shown in FIG. 8A, the lighting fixture 100 and the light source unit 200 are in a state before being attached, and unused parts such as an existing reflector are removed from the lighting fixture 100.
The lighting fixture 100 and the light source unit 200 are disposed apart in the vertical direction Z such that the connecting portion 240 of the light source unit 200 faces the mounting portion 120 .

Next, as shown in FIG. 8(b), the connecting leg 2412 of the connecting part 200 is hooked onto the mounting part 120 of the lighting fixture 100. The light source unit 200 is fixed to the lighting fixture 100 so that the connecting leg 2412 is hooked onto the mounting part 120 by inserting the leg claw part 2412b of the connecting leg 2412 into the gap A between the bottom surface part 111 and the mounting flat surface part 122, and the connecting leg 2412 is hooked onto the mounting part 120 and the connecting movable part 242 side can be moved.

Next, from the state shown in (b) of Figure 8, the light source unit 200 is pushed in the upward direction Z1 so as to rotate the connecting movable portion 242 side toward the bottom surface portion 111 side, with the point where the mounting plane portion 122 and the connecting claw portion 2412b are in contact as the axis.
At this time, as the movable claw portion 2423 slides over the end portion on the short side Y side of the mounting plane portion 122, the movable claw portion 2423 is pressed and moved away from the mounting portion 120, and the movable main body portion 2422 elastically deforms.
When the light source unit 200 is pushed into a position where the movable claw portion 2423 faces the gap A, the movable claw portion 2423 is inserted into the gap A by the restoring force of the movable main body portion 2422 against the deformation. By pushing the movable claw portion 2423 into the gap A, the leg claw portion 2412b and the movable claw portion 2423 are caught on the mounting flat surface portion 122 from the upward direction Z1 side, and the connecting leg portion 2412 and the movable main body portion 2422 hold the mounting portion 120 in the short side direction Y, and the light source unit 200 is attached to the lighting fixture 100.
Through the above steps, as shown in FIG. 8C , the light source unit 200 is attached to the lighting fixture 100 which is a part of an existing lighting device, and the lighting fixture 100 can be retrofitted into the lighting device 1.

In this embodiment, the light source unit 200 includes a connecting portion 240 having a connecting leg portion 2412 and a connecting movable portion 242, and this connecting portion 240 engages with the mounting portion 120 of the lighting fixture 100, thereby enabling the lighting fixture 100 to be remodeled into a lighting device 1. Therefore, when remodeling an existing lighting device, the lighting fixture 100 can be remodeled without discarding it, and the amount of waste materials can be reduced.
Furthermore, the light source unit 200 can be engaged so as to sandwich the mounting portion 120, and can be easily attached without the need for adding or processing members for attachment.

The light source unit 200 is attached by moving it in the short direction Y, and the worker can use the ventilation gap B to perform the work. Therefore, the gap for the attachment work between the second side portion 113 of the fixture body 110 and the light source unit 200 can be made small, and the length of the light source unit and the light source unit 200 in the longitudinal direction X can be made equal to the length of the opening of the lighting fixture 100 in the longitudinal direction X.

In this embodiment, the connecting part 240 has been described as having the connecting leg part 2412 and the connecting movable part 242, but as shown in Fig. 9, the connecting part 240' may have a connecting leg part 2412' having the same configuration as the connecting movable part 242. In this case, the connecting main body part 241' has connecting control parts 2413 provided on both sides in the short direction Y.
Furthermore, the connecting portion 240' can be elastically deformed so that the connecting leg portion 2412' and the connecting movable portion 242 move away from each other, and the light source unit 200' can be fixed to the mounting portion 120 simply by pushing it in the upward direction Z1.

In this embodiment, the lighting fixture 100 has been described as having one fixture body 110, but as shown in FIG. 10, a lighting fixture 100' having two fixture bodies 110 may also be used. The lighting fixture 100' has an installation housing section 3000 between the two fixture bodies 110 in which a facility device 1001 such as a speaker is housed. The lighting fixture 1' can be remodeled into a lighting device 1' by attaching a light source unit 200 to each fixture body 110.

In this embodiment, the connecting portion 240 has been described as being configured such that the connecting movable portion 242 is formed by bending an elastic plate material, but the connecting movable portion 242 may also be formed by bending a wire material. Alternatively, the connecting movable portion 242 may be formed from a material that is difficult to elastically deform, and may be fixed to the connecting body portion 241 using a spring so that it can move.

In this embodiment, the light source unit 200 is described as having a frame reflector 222 on both sides of the short side direction Y of the cover 230, but the cover 230 may be formed long in the short side direction Y without having a frame reflector 222, and may have a ventilation gap B with the first side portion 112 of the fixture body 110.

Embodiment 2.
Next, a description will be given of a light source unit 300 according to the embodiment 2. The light source unit 300 includes a connecting portion 310 that is different from the light source unit 200 according to the embodiment 1. The light source unit 300 will be described with reference to Figs. 11 to 14.
Items in the light source unit 300 of the second embodiment that are not specifically described are the same as those in the light source unit 200 of the first embodiment, and the same functions and configurations are described using the same reference numerals.

The above is an explanation of the configuration of the connecting portion 310 of the light source unit 300. Next, the process of attaching the light source unit 300 to the lighting fixture 100 in order to remodel an existing lighting fixture will be explained with reference to Fig. 14. Note that the lighting fixture 100 has two mounting portions 120 in the longitudinal direction X, and the light source unit 300 has two connecting portions 310 corresponding to the mounting portions 120. Fig. 14 is a reference cross-sectional view seen from the short side direction Y, and each connecting portion 310 is attached to the corresponding mounting portion 120 in the longitudinal direction X by the same process.
Fig. 14 is a reference cross-sectional view showing a process of attaching the light source unit 300 to the lighting fixture 100. Fig. 14(a) shows a state before the lighting fixture 100 and the light source unit 300 are attached. Fig. 14(b) shows a state in which the connecting movable part 3123 of the light source unit 300 abuts against the mounting part 120 of the lighting fixture 100. Fig. 14(c) shows a state in which the connecting movable part 3123 of the light source unit 300 is hooked onto the mounting part 120 of the lighting fixture 100 and the light source unit 300 is attached to the lighting fixture 100.

First, as shown in FIG. 14A, the lighting fixture 100 is in a state before the light source unit 300 is attached, and unused parts such as an existing reflector have been removed.
The lighting fixture 100 and the light source unit 300 are disposed apart in the vertical direction Z such that the connecting portion 310 of the light source unit 200 faces the mounting portion 120 .

Next, as shown in FIG. 14B , in the light source unit 300 , the connecting leg portion 2412 of the connecting portion 310 is brought into contact with the mounting portion 120 of the lighting fixture 100 and slid.
As the light source unit 300 is moved in the upward direction Z1, the second claw portion 3123b of the movable connecting part 312 abuts against an end of the flat mounting part 122. The movable connecting part 312 is held by the connecting body part 311 so as to be movable in the longitudinal direction X, and the second claw portion 3123b is formed so as to be inclined toward the downward direction Z2, so that as the light source unit 300 moves in the upward direction Z1, it moves away from the flat mounting part 122 in the longitudinal direction X.
At this time, the second claw portion 3123b of the movable connecting part 312 has its side surface on the upward Z1 side sliding on the end of the flat mounting part 122. The edge of the movable opening 3121a of the movable connecting part 312 presses the control riser portion 3132c of the connecting control part 313 in the longitudinal direction X in a direction away from the mounting part 120, causing the connecting control part 313 to elastically deform.
In addition, as the light source unit 300 moves upward in the Z1 direction, the leg protrusions 3112ba of the connecting main body 311 are arranged on both sides of the mounting portion 312 in the short direction Y, thereby preventing the light source unit 300 from moving unintentionally in the short direction Y.

Next, as shown in FIG. 14( c ), the second claw portion 3123 b of the light source unit 300 is hooked onto the flat mounting portion 122 , and the light source unit 300 is attached to the lighting fixture 100 .
When the light source unit 300 is moved until the end portion on the downward Z2 side of the second claw portion 3123b is positioned on the upward Z1 side of the flat mounting portion 122, the movable connecting portion 312 is released from pressing the connecting control portion 313, and the second claw portion 3123b is inserted into the gap A by the restoring force of the elastically deformed connecting control portion 313 and hooked onto the horizontal mounting portion 122. Thus, the light source unit 300 is attached to the lighting fixture 100.
Through the above-described steps, the light source unit 300 is attached to the lighting fixture 100 which is a part of an existing lighting device, and the lighting fixture 100 can be retrofitted to the lighting device 1.

Note that FIG. 14 shows the attachment process of the connecting part 310 and the attachment part 120 arranged at one end side in the longitudinal direction X, and the connecting part 310 and the attachment part 120 at the other end side are also attached in the same process. Also, the connecting part 310 is arranged in the light source unit 310 so that the connecting movable part 312 can move from the inside to the outside in the longitudinal direction X by the restoring force of the connecting control part 313.

When removing the light source unit 300 from the fixture body 100, the movable fixing part 3124 is held and the connecting movable part 312 is moved in the longitudinal direction X in a direction away from the mounting part 120, whereby the second claw part 3123b is released from the mounting part 120. Thus, the light source unit 300 can be moved downward in the Z2 direction and removed from the fixture body 100.
The connecting portion 310 is formed to be longer in the short direction Y than the distance between the movable legs 3123 provided in pairs with the movable fixing portion 3124, and is formed so as to be easily grasped from the downward direction Z2 side of the light source unit 300.

In addition, when the light source unit 300 attempts to move in the upward direction Z1, the first claw portion 3122 abuts against the mounting flat surface portion 122, or the side edge of the second claw portion 3123b on the upward Z1 side abuts against the bottom surface portion 111 of the fixture body 110, thereby preventing the light source unit 300 from moving in the upward direction Z1, and the light source unit 300 is stably attached to the fixture body 100.

In this embodiment, the light source unit 300 includes a connecting portion 310 having a connecting movable portion 312 movable in the longitudinal direction X, and the second claw portion 3123b of the connecting movable portion 312 engages with the mounting portion 120 of the lighting fixture 100, thereby allowing the lighting fixture 100 to be remodeled into the lighting device 1. Therefore, when remodeling an existing lighting device, the lighting fixture 100 can be remodeled without discarding it, and the discharge of waste materials can be suppressed.
Furthermore, the light source unit 300 can be engaged by being hooked onto the mounting portion 120, and can be easily attached without the need for adding or processing members for attachment.

In addition, the light source unit 300 has a connecting movable part 312 in which the connecting part 310 moves in the longitudinal direction X, and a connecting control part 313 that controls the movement of the connecting movable part 312, so that it can be attached to the fixture body 100 by pushing it upward in the upward direction Z so as to be stored inside the fixture body 100.
Therefore, the light source unit 300 can be attached even if the gap between the first side surface portion 112 of the fixture body 110 and the light source unit 300 for the attachment work is small.

In the present embodiment, the connecting portion 310 has been described as being configured such that the connecting movable portion 312 moves from the inside to the outside in the longitudinal direction X to hook onto the mounting portion 120, but it may also be configured to move from the outside to the inside to hook depending on the position of the mounting rise portion of the mounting portion. Also, in the longitudinal direction X of the light source unit 300, one of the two connecting portions 310 may move from the inside to the outside to hook onto the mounting portion, and the other connecting portion 310 may move from the outside to the inside to hook onto the mounting portion.

It should be noted that it is possible to appropriately combine the first and second embodiments. For example, the light source unit may include one each of the connecting portion 240 of the first embodiment and the connecting portion 310 of the second embodiment.
It is also possible to combine parts of the first and second embodiments. Furthermore, the present invention is not limited to the first and second embodiments, and can be modified as appropriate.
