  The cover member 23 is formed in a long shape whose upper surface (surface on the mounting member 21 side) is opened by a diffusible material (for example, milky white acrylic resin) (see FIG. 3). Further, the cover member 23 has a convex lens-shaped diffusing surface 231 in which the amount of protrusion downward increases from the both ends to the center in the left-right direction (width direction) (FIG. 1B). reference).

  Furthermore, the both ends of the cover member 23 in the left-right direction overlap with the contact portions 121 of the instrument body 1 in the vertical direction with the light source unit 2 attached to the instrument body 1 as shown in FIG. Each extending portion 232 is provided. Further, leg portions 233 each having a hook portion 233a at the tip and extending upward (on the attachment member 21 side) are provided over the entire length inside each extension portion 232 in the left-right direction of the cover member 23. Yes.

  The power supply device 24 includes a power supply board 241 and a storage case 242 for storing the power supply board 241. The power supply board 241 includes a printed board 241a formed in a rectangular plate shape that is long in the front-rear direction. The printed board 241a includes electronic components (for example, a transformer, a diode, a capacitor, etc.) 241b for generating at least the lighting power of the LED 222. Has been implemented.

  As shown in FIG. 3, the storage case 242 is formed in a rectangular box shape with one surface (a surface facing the bottom surface portion 211 of the mounting member 21) open and long in the front-rear direction. The storage case 242 is attached to the side surface portion 212 of the mounting member 21 using, for example, screws, such that the opening side faces the bottom surface portion 211 of the mounting member 21.

  Here, in FIGS. 1A and 2B, the hook portion 261 a of the locking metal fitting 26 is hooked on the opening edge of the insertion hole 271 a of the holding metal fitting 27, and the light source unit 2 is temporarily held on the instrument main body 1. State. At this time, the locking metal fitting 26 is in the state of being most pulled out to the left side with respect to the mounting member 21, and the protrusion 262a is engaged with the first engagement hole 251b (FIGS. 1A and 1). (See (c)).

  Then, when the light source unit 2 is rotated counterclockwise with the hooking portion 261a side as the rotation center from this state, the locking spring 28 engages with a locking portion (not shown) provided in the instrument body 1. The light source unit 2 is attached to the instrument body 1 (see FIG. 1B). At this time, the locking metal fitting 26 abuts the side surface portion 12 through the insertion hole 271a, and the engagement state between the protrusion 262a and the first engagement hole 251b is released by the reaction force from the side surface portion 12, and the locking metal fitting 26 is released. Moves to the right.

  In a state where the light source unit 2 is attached to the instrument main body 1, the locking member 26 is most retracted with respect to the attachment member 21, and the protrusion 262a is engaged with the second engagement hole 251c (FIG. 1). (See (b)).

  Next, the assembly procedure of the light source unit 2 will be described. First, the operator fixes the power supply device 24 to the upper surface of the bottom surface portion 211 of the mounting member 21, and further fixes the two substrates 22, 22 to the lower surface of the bottom surface portion 211 of the mounting member 21 by the locking claws. To do. Thereafter, the operator passes the electric wire led out from the connector 223 of the board 22 through the hole 211 a provided in the bottom surface portion 211 of the mounting member 21, and connects the end portion to the power supply device 24.

  Finally, the operator attaches the cover member 23 to the attachment member 21 with the opening side facing upward. At this time, the hook portion 233a of each leg portion 233 engages with the corresponding protrusion 212a of the side surface portion 212. The light source unit 2 is assembled by the above procedure.

  Then, the construction procedure of the lighting fixture A is demonstrated. First, an operator passes a power line (not shown) wired in advance on the back of the ceiling through a hole (not shown) in the protruding portion 111 of the instrument body 1 and then is exposed from the ceiling material 100. A bolt (not shown) is passed through a hole (not shown) in the projecting portion 112. Furthermore, an operator screws a nut (not shown) into the suspension bolt to fix the appliance body 1 to the ceiling material 100.

  Thereafter, the worker connects the end of the power line to the terminal block, and further connects the terminal block and the power supply device 24 with an electric wire. Finally, the operator hooks the hooking portion 261a of the locking metal fitting 26 on the opening edge of the insertion hole 271a of the holding metal fitting 27, and then rotates the light source unit 2 around the hooking portion 261a. The locking spring 28 is engaged with the locking portion of the instrument body 1. Thereby, the light source unit 2 is attached to the fixture main body 1, and construction of the lighting fixture A is completed.

  As described above, when the light source unit 2 is attached to the instrument main body 1, the locking metal fitting 26 comes into contact with the side surface portion 12 of the instrument main body 1 and is pulled out most with respect to the attachment member 21 by the reaction force from the side surface portion 12. The locking fitting 26 moves from the first position to the most retracted second position. Therefore, the space for releasing the locking metal fitting 26 can be reduced, and thereby the appliance body 1 can be prevented from becoming longer in the width direction.

  Moreover, the width dimension of the extension part 232 of the cover member 23 in which the light from LED222 cannot reach easily can be made small by suppressing the width dimension of the instrument main body 1. FIG. Further, when the light source unit 2 is temporarily held on the instrument body 1, the protrusion 262 a is engaged with the first engagement hole 251 b, and when the light source unit 2 is attached to the instrument body 1, the protrusion 262 a is the second engagement. Engages with the joint hole 251c. Thereby, it can suppress that the latching metal fitting 26 slides in the width direction in each state.
