The spring hook 251 forms a frame opening 251c. In the light source unit 200, the spring hooking portion 251 holds the second plate portion 223 between the hooking claw portion 251a and the hooking plate portion 251b.

  The hooking claw 251a is formed obliquely with respect to the spring bottom surface 252b so as to be hooked on the second plate 223 of the frame 220. The hook hook 251a is formed at the tip of the spring hook 251 and includes two hook-shaped hooks 251a1 facing each other. Each claw portion 251a1 is formed in an L shape, and is arranged so that the protruding portions face each other. In the light source unit 200, the pillar 222 of the frame 220 is inserted between the two claws 251a1 facing each other.

  The hook plate portion 251b contacts the second plate portion 223 in the light source unit 200 so as to be hooked on the second plate portion 223 of the frame 220. The hooking plate portion 251b is formed in a substantially Y-shape, and a claw portion 251a1 of the spring hooking portion 251 is formed at a branching end portion. The hook plate 251b has an end opposite to the branching side connected to the spring bottom surface 252b of the spring body 252 via a spring plate 251d. The hook plate portion 251b is disposed substantially parallel to a virtual extension surface of the spring bottom portion 252b. Note that the hook plate portion 251b is not limited to a configuration that is substantially parallel to the virtual extension surface of the spring bottom surface portion 252b. The hook plate 251b may be formed such that, for example, the inclination of the hook plate 251b with respect to the spring bottom 252b is smaller than the inclination of the hook claw 251a with respect to the spring bottom 252b.

  The spring plate portion 251d is a rectangular plate-shaped member provided between the hook plate portion 251b and the spring bottom portion 252b. The spring plate 251d is formed obliquely with respect to the spring bottom 252b. The spring plate part 251d plays a role of forming a space between the spring bottom part 252b and the second plate part 223 in the light source unit 200. That is, when the spring 250 is attached to the frame 220, a gap is formed between the spring bottom portion 252b and the second plate portion 223.

  The spring hooking portion 251 has a frame opening 251c into which the second plate portion 223 is inserted by the end 251a2 of the hooking claw 251a and the end 251b1 of the hooking plate 251b. The end 251a2 of the hook claw 251a is the end on the spring body 252 side and the end on the hook plate 251b side in the longitudinal direction (X-axis direction) of the light source unit 200. The end 251b1 of the hook plate 251b is an end on the hook claw 251a side in the longitudinal direction (X-axis direction) of the light source unit 200. The frame opening 251c is formed so as to cut out a part of the hook plate 251b. In other words, the frame opening 251c is formed by a part of the hook claw 251a and a part of the hook plate 251b.

  The distance between the end portion 251a2 of the hooking claw portion 251a and the end portion 251b1 of the hooking plate portion 251b is large enough to hold the second plate portion 223 by the hooking claw portion 251a and the hooking plate portion 251b.

(Modification of end cap 240)
FIG. 22 is a perspective view of a modification of the end cap 240 of FIG. 9 as viewed from the outside. FIG. 23 is a perspective view seen from the inside of the end cap 1240 of FIG. An end cap 1240 which is a modification of the end cap 240 will be described with reference to FIGS. In the following description of the end cap 1240, the same parts as those of the end cap 240 are denoted by the same reference numerals, and the description thereof will be omitted. The description will focus on differences from the end cap 240.

  The end cap 1240 has a cover cap portion 241, a first projecting portion 1242, a second projecting portion 243, a frame cap portion 244, a first support portion 245, and a second support portion 246.

  The first protruding portion 1242 is provided in the light source unit 200 so as to protrude from the cover cap portion 241 so as to abut on the inner side surface portion 230 a of the cover 230. More specifically, in the light source unit 200, the first projecting portion 1242 abuts the main cover portion 231 of the cover 230 and the inner side surface portion 230a of the cover side surface portion 232, and a part of the second cover holding portion 221c. Is provided. In the light source unit 200, the first protruding portion 1242 has a top plate portion 1242a that contacts the inner surface portion 230a of the main cover portion 231 and a side plate portion 1242b that contacts the inner surface portion 230a of the cover side surface portion 232. The first protruding portion 1242 forms a wall protruding from the cover cap portion 241 by the top plate portion 1242a and the two opposing side plate portions 1242b. The first projecting portion 1242 closes the space between the end 230 t of the cover 230 and the cover cap portion 241 in the light source unit 200. The cover 230 is slidably in contact with the first protruding portion 1242.

  The first protrusion 1242 may be formed of a plurality of different transmissive materials. More specifically, the first projecting portion 1242 may be formed of a different transmissive material from the middle of the direction in which the first projecting portion 1242 extends in the longitudinal direction (X-axis direction) of the light source unit 200. For example, in the first protruding portion 1242, the portions indicated by the regions A and B divided by the dotted line M in FIGS. 22 and 23 may be made of different transmissive materials. The first projecting portion 1242 is formed such that the region A on the distal end side and the region B on the base side have different transmittances in the protruding direction. By using a material having high permeability from the middle of the first projecting portion 1242, a portion of the first projecting portion 1242 that does not overlap with the cover 230 can be made of a material having low permeability. For example, the tip side in the projecting direction of the first projecting portion 1242 is defined as a region A, and the cover cap portion 241 side, which is the base side in the projecting direction of the first projecting portion 1242, is defined as the region B.

For example, the first protruding portion 1242 is formed such that the portion of the region A is transparent and the portion of the region B is formed of a milk half having substantially the same transparency as the cover 230. The first protruding portion 1242 is formed by forming the portion of the region A transparent and forming the portion of the region B in a milk half having substantially the same transparency as the cover 230 so that the first protrusion of the portion overlapping the cover 230 can be formed. The light transmittance of the setting portion 1242 is improved. Therefore, the light source unit 200 can suppress light unevenness as a whole. This end cap 1240 can be formed by two-color molding.

  Note that the first projecting portion 1242 is not limited to a configuration in which the region A is formed of a material having high transparency and the region B is formed of a material having low permeability. The first projecting portion 1242 may be formed by forming a portion of the region A with a material having low permeability and forming a portion of the region B with a material having high permeability. For example, the first protruding portion 1242 may be configured such that a portion of the region B is formed transparent and a portion of the region A is formed of a milk half having substantially the same transparency as the cover 230. In this case, since the portion of the region B that does not overlap with the cover 230 is transparent, the first projecting portion 1242 can increase the amount of light emitted from the portion of the region B, and can make the portion look bright. .

  FIG. 24 is an enlarged view of a combined portion of the end cap 240 of FIG. 9 and an end cap 2240 and a cover 230 of another modified example. An end cap 2240 which is a modification of the end cap 240 will be described with reference to FIG.

By forming the inner end 351 in an R-shape in this manner, it becomes easier to insert the electric wire when pushing the electric wire from outside to inside of the lighting fixture 100 into the connection main body 310 through the main body opening 113. Further, by making the outer end portion 352 have a substantially right angle, the main body engaging portion 1350 is easily caught by the convex portion 114, and the connecting member 2300 is less likely to come off the lighting fixture 100.

[Instrument side spring 160]
FIG. 36 is a perspective view of the fixture-side spring 160 of the lighting device 1 according to the embodiment of the present invention. With reference to FIG. 36, a description will be given of the fixture-side spring 160, which is an optional component of the lighting device 1 according to the embodiment. When the lighting device 1 is formed to be long, the vicinity of the center of the light source unit 200 may be bent. In such a case, it is preferable to attach the fixture-side spring 160 to the lighting device 1. The device-side spring 160 is formed of an elastic body, and fixes the light source unit 200 to the device main body 110. The device-side spring 160 is provided in a pair at a position near substantially the center of the device body 110 in the longitudinal direction (X-axis direction). That is, the fixture-side spring 160 is arranged on the center side with respect to the end of the lighting fixture 100 in the longitudinal direction (X-axis direction). Further, the appliance-side spring 160 is arranged at a position such that the power supply device 120 is avoided in the longitudinal direction (X-axis direction) of the appliance main body 110.

The spring arm 162 is a portion that engages with the light source unit 200 at the central portion 165 of the instrument-side spring 160. The spring engagement portion 161a is a portion formed integrally with the spring extension portion 161 and is a portion formed by bending a wire into a circular shape. The spring engagement portions 161 a are portions that respectively engage with the protrusions 114 of the two side surfaces 112 of the instrument body 110 at the ends of the instrument-side spring 160.

  The engagement spring portion 160a also has a spring restricting portion 160a1 at an end connected to the spring connection portion 160b. The two spring restricting portions 160a1 forming a pair are inclined so that the distance therebetween increases from the spring arm portion 162 toward the spring connecting portion 160b. In other words, the pair of spring restrictors 160a1 are inclined so that the distance from each other decreases from the spring connection 160b toward the spring arm 162. The spring throttle portion 160a1 has a spring bent portion 160a2 which is bent in the opposite direction to the tilt direction and is connected to the spring arm portion 162. The spring bent portion 160a2 is formed by bending into a substantially L-shape. The device-side spring 160 is formed such that the pair of spring bent portions 160a2 is convex in the direction facing each other.

  The device-side spring 160 is arranged such that the distance between the two spring bent portions 160a2 in the lateral direction (Y-axis direction) of the lighting device 1 is shorter than the length of the spring connection portion 160b in the extending direction.

[Mounting process of light source unit 200]
FIG. 37 is a reference diagram illustrating the attachment of the light source unit 200 to the lighting fixture 100 in a state where the fixture-side spring 160 and the light source unit 200 in FIG. 36 are in contact with each other. FIG. 38 is a reference diagram illustrating the attachment of the light source unit 200 to the lighting fixture 100 in a state where the fixture-side spring 160 and the light source unit 200 of FIG. 37 are engaged. The process of attaching the light source unit 200 to the lighting fixture 100 using the fixture spring 160 will be described with reference to FIGS. 37 and 38.

  First, the worker installs the fixture-side spring 160 inside the fixture main body 110 of the lighting fixture 100. The operator slides the spring engaging portion 161a to the convex portion 114 and inserts the device-side spring 160 into the device main body 110. At this time, the spring extension 161 contacts the convex 114. Further, the spring arm portion 162 and the spring extension portion 161 are elastically deformed inward in the short direction (Y-axis direction) of the lighting fixture 100, and are pushed until the spring engaging portion 161 a passes through the convex portion 114. When the spring engaging portion 161a passes through the convex portion 114, the elastic deformation of the spring arm portion 162 and the spring extending portion 161 of the device-side spring 160 is released, and the spring engaging portion 161a is hooked on the convex portion 114.

  In order to further ensure the engagement between the spring engaging portion 161a and the convex portion 114, the convex portion 114 is cut into a part of the convex portion 114 like a first all-notch portion 114b shown in FIG. A missing spring mounting portion 115 may be formed. Then, the spring engaging portion 161a may be inserted into and fixed to the spring mounting portion 115. When the device-side spring 160 is installed on the device main body 110, the device-side spring 160 engages with the spring mounting portion 115 and the spring extension 161 extends from the convex portion 114 to the bottom 111 side of the device main body 110. I do. The spring arm 162 is arranged to be inclined from the end of the spring extension 161 on the bottom 111 side toward the second plate 223 of the frame 220.

  The device-side spring 160 makes the fulcrum of elastic deformation of the spring arm portion 162 closer to the bottom 111 of the device main body 110 because the spring extension 161 extends from the convex portion 114 to the bottom 111 of the device main body 110. be able to. Therefore, the length of the spring arm portion 162 can be ensured, and the resistance component of the side portion 112 against elastic deformation can be reduced, so that the spring arm portion 162 can be easily elastically deformed when elastically deformed. In addition, since the appliance-side spring 160 is provided on the convex portion 114 of the appliance main body 110, the space inside the appliance main body 110 can be effectively used.

  When attaching the light source unit 200 to the lighting fixture 100, the worker brings the end of the second plate portion 223 of the frame 220 into contact with the spring contraction part 160a1 of the fixture-side spring 160 as shown in FIG. The operator pushes the light source unit 200 into the instrument main body 110 from a state where the end of the second plate portion 223 of the frame 220 is in contact with the spring drawing portion 160a1. Then, as shown in FIG. 38, the end of the second plate portion 223 of the frame 220 slides on the spring restrictor 160a1 along the inclination of the spring restrictor 160a1. At this time, the spring arm portion 162 is elastically deformed outward in the short direction (Y-axis direction) of the lighting device 100, and is pushed until the first plate portion 221 contacts the upper end of the convex portion 114. That is, when the light source unit 200 is attached to the lighting fixture 100, the second plate portion 223 comes into contact with the spring diaphragm 160 a 1 and slides, and the spring arm 162 moves in the short direction (Y-axis direction) of the lighting fixture 100. ). Thereafter, in the light source unit 200, the end of the second plate portion 223 finishes sliding with respect to the spring diaphragm portion 160a1, the elastic deformation of the spring arm portion 162 is released, and the second plate portion 223 is moved to the end portion of the spring arm portion 162. Is caught and held. The spring arm portion 162 can hold the light source unit 200 when the distal end contacts the second plate portion 223 of the frame 220. Therefore, in the instrument-side spring 160, the spring engaging portion 161 a as the end portion engages with the convex portions 114 of the two side surface portions 112, respectively. The instrument-side spring 160 has a central portion 165 located between the spring engaging portions 161a, which are both ends, formed by a spring arm portion 162. The spring arm portion 162 is connected to the second plate portion 223 of the light source unit 200. Engage with. In a state where the light source unit 200 is attached to the lighting fixture 100, the second plate portion 223 is held between the spring arms 162.

[Operation of instrument side spring 160]
In the lighting device 1, the light source unit 200 is attached to the lighting fixture 100 by the springs 250 at both ends 200 a in the longitudinal direction (X-axis direction), and the fixture-side spring 160 is located substantially at the center in the longitudinal direction (X-axis direction). Thereby, the light source unit 200 is held by the lighting fixture 100. As a result, the light source unit 200 is fixed to the lighting fixture 100 without bending.

  In the lighting device 1, the fixture-side spring 160 is used to prevent the intermediate portion of the light source unit 200 from bending. However, the illumination device 1 improves the holding force of the instrument-side spring 160, for example, by being formed of a leaf spring, and holds the light source unit 200 only with the instrument-side spring 160 by providing a plurality of instrument-side springs 160. You may do so.

  In addition, when the spring extension 161 abuts on the side surface portion 112 or the power supply device 120, the instrument-side spring 160 becomes a reaction force against the force with which the light source unit 200 is pushed in, and the spring arm portion 162 forms the second end of the frame 220. The two plates 223 can be sandwiched. By contacting the spring extending portion 161 with the side surface portion 112 or the power supply device 120, the frame 220 can be held without increasing the rigidity of the spring itself.

  The device-side spring 160 does not have to be firmly attached to the protrusion 114, for example, by being fixed with a fixture such as a screw. In the case of the instrument-side spring 160, the end is fitted in the spring mounting portion 115 in which the projection 114 is partially cut out inside the projection 114 in the longitudinal direction (X-axis direction).

  The device-side spring 160 is more easily elastically deformed than the spring 250. In the lighting device 1, since the fixture-side spring 160 is more easily elastically deformed than the spring 250, the light source unit 200 can be easily attached to the lighting fixture 100 when an operator pushes the light source unit 200 into the lighting fixture 100.

The plate-shaped spring contraction portion 1160a1 is a plate-shaped spring arm portion. It is formed integrally with the tip of 1162. In the projecting direction of the engagement spring portion 1160a, the spring arm portion 1162 and the spring throttle portion 1160a1 are formed in this order from the spring connection portion 1160b. The two opposing spring arms 1162 are configured such that their tips approach each other in the direction in which the engagement spring portion 1160a protrudes, and the two opposing spring restrictors 1160a1 are configured such that the tips are separated. I have. In other words, the two spring arms 1162 forming a pair are inclined such that the distance therebetween increases from the spring restricting portion 1160a1 toward the spring connecting portion 1160b. Therefore, the cross-sectional shape of the integrally formed spring squeezed portion 1160a1 and spring arm portion 1162 in the protruding direction is substantially L-shaped. Therefore, the instrument-side spring 1160 is formed such that the two sets of opposing spring squeezed portions 1160a1 and the spring arms 1162 are convex in the direction facing each other.

  The engagement spring portion 1160a further has a spring extension 1161. The spring extension portion 1161 is formed outside the spring throttle portion 1160a1 and the spring arm portion 1162 in the direction in which the spring connection portion 1160b extends.

The spring engaging portion 1161c has an outer projecting portion 1161c1 that is located on the distal end side in the direction in which the spring extending flat portion 1161b extends, and that projects in a direction substantially perpendicular to the plate surface of the spring extending flat portion 1161b. Further, the spring engaging portion 1161c is located inside the outer projecting portion 1161c1, projects substantially perpendicularly to the plate surface of the spring extending flat portion 1161b, and is formed higher than the outer projecting portion 1161c1. It has a protrusion 1161c2. The spring engaging portion 1161c forms a groove 1161c3 by the outer projecting portion 1161c1 and the inner projecting portion 1161c2. The spring engaging portion 1161c is a portion that engages with the convex portion 114 of the two side portions 112 of the instrument main body 110 at the ends of the instrument side spring 1160, respectively.

  The instrument-side spring 1160 is arranged such that the distance between the distal ends of the spring arms 1162 is shorter in the lateral direction (Y-axis direction) of the lighting device 1 than in the direction in which the spring connection portion 1160b extends. The arm 1162 is inclined. The device-side spring 1160 has a longer distance between the distal ends of the two spring diaphragms 1160a1 than the distance between the distal ends of the spring arms 1162 in the lateral direction (Y-axis direction) of the lighting device 1. Thus, the spring restricting portion 1160a1 is inclined. Further, in the instrument-side spring 1160, the spring extension portion 1161 is inclined such that the distance between the two spring extension inclined portions 1161a is longer than the distance between the two spring contraction portions 1160a1.

The process of attaching the light source unit 200 to the lighting fixture 100 using the fixture-side spring 1160 will be described with reference to FIGS. 40 and 41.

  The operator first installs the fixture-side spring 1160 inside the fixture main body 110 of the lighting fixture 100. The operator slides the spring engaging portion 1161c to the convex portion 114 and inserts the device-side spring 1160 into the device main body 110. At this time, the spring extension portion 1161 is elastically deformed inward in the short direction (Y-axis direction) of the lighting fixture 100, and is pushed until the spring engagement portion 1161 c passes through the projection 114. When the spring engaging portion 1161c passes through the convex portion 114, the elastic extension of the spring extension portion 1161 is released, and the spring engaging portion 1161c is hooked on the convex portion 114. In this state, the device-side spring 1160 is attached to the projection 114 so as to cover the main body opening 113 of the device main body 110.

  In order to further secure the engagement between the spring engaging portion 1161c and the convex portion 114, the convex portion 114 is cut into a part of the convex portion 114 as shown in FIG. A missing spring mounting portion 115 may be formed. Then, the spring engaging portion 1161c may be engaged with the spring mounting portion 115. When the device-side spring 1160 is installed on the device main body 110, the device-side spring 1160 has the spring engaging portion 1161c inserted into the spring mounting portion 115, and the spring connection portion 1160b faces the power supply device 120 and is not in contact with the power source device 120. It is arranged so that it may touch. At this time, the wall of the protrusion 114 is inserted into the groove 1161c3.

  When attaching the light source unit 200 to the lighting fixture 100, the operator causes the end of the second plate portion 223 of the frame 220 to abut on the spring diaphragm 1160 a 1 of the fixture-side spring 160. The operator pushes the light source unit 200 into the instrument main body 110 from a state in which the end of the second plate portion 223 of the frame 220 is in contact with the spring drawing portion 1160a1. Then, the end of the second plate portion 223 of the frame 220 slides on the spring drawn portion 1160a1 along the inclination of the spring drawn portion 1160a1. At this time, the spring arm portion 1162 is elastically deformed outward in the short direction (Y-axis direction) of the lighting device 100, and is pushed until the first plate portion 221 contacts the upper end of the convex portion 114. That is, when the light source unit 200 is attached to the lighting fixture 100, the second plate portion 223 comes into contact with the spring diaphragm 1160 a 1, and the spring arm 1162 is elastically deformed in the short direction (Y-axis direction) of the lighting fixture 100.

Thereafter, in the light source unit 200, the end of the second plate portion 223 finishes sliding with respect to the spring restricting portion 1160a1, the elastic deformation of the spring arm 1162 is released, and the second plate portion 223 is moved to the end of the spring arm 1162. Is caught and held. Then, the instrument side spring 1160 holds the second plate portion 223 so as to sandwich the second plate portion 223 of the frame 220. The spring arm portion 1162 can hold the light source unit 200 when its tip is in contact with the second plate portion 223 of the frame 220. Therefore, the device-side spring 1160 has the spring engaging portion 1161c, which is the end portion, engaged with the convex portions 114 of the two side surface portions 112, respectively. The instrument-side spring 1160 has a central portion 165 located between the spring engaging portions 1161c, which are both ends, formed by a spring arm 1162, and the spring arm 1162 is connected to the second plate portion 223 of the light source unit 200.

Thereby, the light source unit 200 is held by the lighting fixture 100. As a result, the light source unit 200 is fixed to the lighting fixture 100 without bending.

  The appliance-side spring 1160 is arranged so that the second plate portion 223 of the frame 220 faces the power supply device 120, so that when the light source unit 200 is pressed, the appliance-side spring 1160 is connected to the power supply device 120. It does not come off to abut. The device-side spring 1160 becomes a reaction force against the force of pushing the light source unit 200 when the spring extension portion 1161 comes into contact with the side surface portion 112 or the power supply device 120, and the second plate of the frame 220 is formed by the spring constriction portion 1160a1. The part 223 can be sandwiched. By contacting the spring extending portion 1161 with the side surface portion 112 or the power supply device 120, the frame 220 can be held without increasing the rigidity of the spring itself.

  Note that the instrument-side spring 1160 does not have to be firmly attached to the protrusion 114, for example, by being fixed with a fixture such as a screw. In the device-side spring 1160, a wall constituting the convex portion 114 is inserted into the groove portion 1161c3 of the spring engaging portion 1161c in the spring mounting portion 115 at a location where the convex portion 114 is partially cut away. The appliance-side spring 1160 is arranged such that the spring connection portion 1160b faces the power supply device 120 and the power supply device 120 contacts. Therefore, the instrument-side spring 1160 is attached so as to be sandwiched between the protrusion 114 and the power supply device 120.

[Operation of mounting base 400]
In the mounting base 400, a control A section 412 and a control B section 422 are slidably connected by a shaft section 430. The mounting base 400 includes a control hole 412b, which is an A portion first engagement portion formed on the control A portion 412, and a control convex portion 422b, which is a B portion second engagement portion formed on the control B portion 422. Engages to hold the lighting fixture 100 rotatably. In the mounting base 400, the inclination angle of the mounting part 420 with respect to the pedestal part 410 is determined by fitting the control protrusion 422b into any one of the plurality of control holes 412b. As shown in FIGS. 44 and 45, the control protrusion 422b is fitted into the control hole 412b while sliding the control A portion 412 of the pedestal 410, and the mounting portion 420 is set at a predetermined angle with respect to the pedestal 410. Can be held. As shown in FIG. 44, the mounting base 400 has legs 411 formed longer than the short direction (Y-axis direction) of the lighting device 1.

  As shown in FIG. 44, when the control projection 422b is engaged with the control hole 412b formed at the position closest to the leg 411, the leg 411 and the mounting plate 421 are arranged substantially in parallel. You.

[Function and Effect of Frame 220]
The effect of the illumination device 1 according to the embodiment, that is, the reduction in thickness of the illumination device 1 by the frame 220 will be described below. In the light source unit 200, the frame 220 connects the first plate portion 221 to which the light emitting module 210 is mounted, the second plate portion 223 facing the first plate portion 221, and the first plate portion 221 and the second plate portion 223. The rigidity can be ensured by having the pillar portion 222 that does. Therefore, the light source unit 200 can be reduced in thickness without increasing in the vertical direction (Z-axis direction). As a result, the lighting device 1 having the light source unit 200 can be thinned in the vertical direction (Z-axis direction).

  Further, in the lighting device 1, since the light source unit 200 is thinned, the internal space of the fixture body 110 can be effectively used. Specifically, the light source unit 200 can be attached to the lighting fixture 100 such that the light source unit 200 does not interfere with components housed in the fixture main body 110 such as the power supply device 120 by reducing the thickness of the light source unit 200. In addition, since the light source unit 200 is thinned, the device main body 110 can divide the region in which the light source unit 200 is accommodated and the region in which the power supply device 120 and the like are accommodated in the vertical direction (Z axis direction). it can. The lighting device 1 can move the power supply device 120 to one side in the short direction (Y-axis direction) by dividing the inside of the fixture body 110 up and down. For this reason, the lighting device 1 can provide a place for accommodating the electric wires in the device in the short direction (the Y-axis direction) of the device main body 110, and can suppress an increase in the size of the lighting device 1. In addition, the lighting device 1 can prevent the electric wire from being sandwiched between the light source unit 200 and the power supply device 120 by accommodating the electric wire in the appliance in the short direction (Y-axis direction) of the appliance main body 110. it can. With these configurations, the lighting device 1 can be downsized.

[Operation and Effect of Spring 250]
In the lighting device 1, a spring 250 fixed to the light source unit 200 has a spring bottom portion 252 b formed in a flat plate shape and formed at both ends of the spring bottom portion 252 b, and a short direction (Y-axis direction) of the light source unit 200. And a spring claw portion 252a that elastically deforms. Further, the spring 250 has a spring engaging portion 252c formed at the tip of the spring claw portion 252a. Then, the distance L1 between the closest portions of the corresponding two convex portions 114 is smaller than the distance between the farthest portions of the two opposing spring engaging portions 252c in the natural length of the spring claw portion 252a. Therefore, the worker presses the light source unit 200 into the lighting fixture 100 by utilizing the elastic deformation of the spring 250, so that the light source unit 200 can be engaged with the projection 114 of the fixture main body 110 via the spring 250. it can. In addition, the worker can remove the light source unit 200 from the lighting fixture 100 by using the elastic deformation of the spring 250 by pulling out the light source unit 200 from the lighting fixture 100. As a result, the lighting device 1 can easily attach and detach the light source unit 200 to and from the lighting fixture 100.

  When the light source unit 200 is attached to the lighting fixture 100, the spring 250 engages the spring engaging portion 252c with the convex portion 114. Therefore, the lighting device 1 does not need to provide a separate member for engaging with the spring 250 in the fixture main body 110 of the lighting fixture 100, and the number of members can be reduced. Therefore, the lighting device 1 can reduce the number of components housed in the fixture main body 110 and can effectively utilize the internal space.

  When the light source unit 200 is attached to the lighting fixture 100, a portion of the spring engaging portion 252c of the spring 250 that faces the side surface portion 112 is formed in an arc shape. Therefore, when the worker removes the light source unit 200 from the lighting fixture 100, the light source unit 200 can be easily removed from the lighting fixture 100 without a special jig for facilitating attachment and detachment of the light source unit 200. In addition, when the operator attaches the light source unit 200 to the lighting fixture 100, the light source unit 200 can be easily attached to the lighting fixture 100 without a special jig for facilitating attachment and detachment of the light source unit 200.

  The spring 250 is formed such that when the light source unit 200 is attached to the lighting fixture 100, the spring claw 252 a does not protrude toward the bottom 111 from the spring bottom part 252 b inside the lighting fixture 100. Therefore, the illumination device 1 can suppress interference with other members inside the instrument main body 110 when the spring claw portion 252a is elastically deformed. In addition, in the lighting device 1, for example, a member such as an electric wire disposed inside the appliance main body 110 can also be prevented from being damaged by interference with the spring claw portion 252a.

  The spring 250 is formed in a V-shape such that the spring claw portion 252a is convex on one surface side of the spring bottom surface portion 252b. Therefore, the illumination device 1 can suppress interference with other members inside the instrument main body 110 when the spring claw portion 252a is elastically deformed. In addition, in the lighting device 1, for example, a member such as an electric wire disposed inside the appliance main body 110 can also be prevented from being damaged by interference with the spring claw portion 252a.

  A plurality of spring claws 252a of the spring 250 are formed in the longitudinal direction (X-axis direction) of the light source unit 200, and an opening is formed between adjacent spring claws 252a. The spring 250 can be easily elastically deformed by forming an opening between the adjacent spring claws 252a. In addition, the spring 250 can adjust the elasticity of the spring 250 by the size of the opening formed between the adjacent spring claws 252a, thereby adjusting the elastic strength and reducing the weight of the spring formed of a plate material. Can be.

  When the light source unit 200 is attached to the lighting fixture 100, the spring engaging portion 252 c comes into contact with the convex portion 114 and slides, and the spring claw 252 a is elastic in the short direction (Y-axis direction) of the lighting fixture 100. Deform. Therefore, when the worker pushes the light source unit 200 into the lighting fixture 100 in the up-down direction (Z-axis direction) of the lighting device 1, the spring engagement portion 252 c engages with the projection 114 of the lighting fixture 100, and the light source unit 200 can be easily fixed to lighting fixture 100. Further, when the worker inserts the light source unit 200 into the lighting fixture 100, the spring engagement portion 252c serves as a guide for the light source unit 200 with respect to the lighting fixture 100, and the worker can easily attach the light source unit 200. Therefore, since the spring engagement portion 252c serves as a guide for the light source unit 200 with respect to the lighting device 100, when the lighting device 1 is used as indirect lighting or the like, the light source unit 200 can be used even in a space where the lighting device 1 is small. 100 can be easily attached.

  The spring 250 forms an interval between the spring bottom surface portion 252b and the second plate portion 223 when attached to the frame 220. Therefore, the spring 250 can increase the distance between the end of the spring engaging portion 252c that contacts the convex portion 114 and the end (fulcrum) of the V-shaped apex of the spring claw 252a. The spring 250 can be easily elastically deformed.

  In the light source unit 200, when the frame 220 is inserted into the lighting fixture 100, the first plate portion 221 contacts the convex portion 114 when the spring engaging portion 252 c is disposed below the convex portion 114. Therefore, when the worker inserts the light source unit 200 into the lighting fixture 100, the light source unit 200 is prevented from entering the inside of the fixture main body 110 by a predetermined distance or more, and the inside of the light source unit 200 and the lighting fixture 100 is suppressed. Interference with parts can be prevented.

  The spring hook 251 of the spring 250 has two hook-shaped claws 251a1 facing each other at the distal end. Therefore, the end of the spring 250 can be hooked on the second plate portion 223 of the frame 220.

  It is to be noted that in the lighting device in which the light source unit is detachably attached to the lighting fixture, it is conceivable that the lighting device has a spring for attaching the light source unit to the lighting fixture so as to be drawn inside the fixture main body. Can be In the case of such an illuminating device, it is conceivable that a part of the light source unit is drawn inside the fixture main body in the longitudinal direction (X-axis direction) of the illuminating device due to the strong force of the spring. On the other hand, as in the case of the lighting device 1, such a method is employed in which the lighting device 1 is gripped in the short direction (Y-axis direction) by the projection 114 and the spring engagement portion 252c of the fixture body 110. Can also be prevented.

[Operation and Effect of End Cap 240]
The light source unit 200 includes a cover 230 having an opening 230c formed at an end 230t in a longitudinal direction (X-axis direction) when attached to the frame 220, and an end cap 240 fixed to the frame 220 and closing the opening 230c. And In the light source unit 200, since the end cap 240 is fixed to the frame 220, even if the cover 230 contracts due to heat, the end cap 240 not fixed to the cover 230 is not affected. Therefore, even if the light source unit 200 is affected by heat, the load on each part of the light source unit 200 can be suppressed.

  The end cap 240 is fixed to the frame 220, and the length in the longitudinal direction (X-axis direction) of the cover 230 is shorter than the opposing length between the two cover cap portions 241 arranged at both ends of the frame 220. Is formed. Therefore, the lighting device 1 can suppress expansion and contraction of the light source unit 200 in the longitudinal direction (X-axis direction) without being affected by expansion and contraction of the cover 230 due to the influence of heat (ambient temperature).
