  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

  FIG. 1 is a diagram illustrating a configuration of a light emitting device 10 according to the embodiment. The light emitting device 10 according to this embodiment includes a surface light source fixing device 100 and a surface light source 200. The surface light source 200 is arranged on the arrangement surface 102 of the surface light source fixing device 100. A fixing member 210 is provided on a surface 202 of the surface light source 200 that faces the arrangement surface 102. The fixing member 210 protrudes from the surface 202.

  The surface light source fixing device 100 has an engaging portion 105. The engaging portion 105 engages with the fixing member 210 in a state where the surface light source 200 is disposed on the arrangement surface 102. In the example shown in the figure, an opening 104 is provided in the arrangement surface 102 of the surface light source fixing device 100, and a hollow portion 106 is provided in the surface light source fixing device 100. The hollow portion 106 is provided to accommodate the engaging portion 105. The opening 104 is provided at a position facing the fixing member 210 in a state where the surface light source 200 is disposed on the arrangement surface 102. The opening 104 is connected to the hollow portion 106. The fixing member 210 enters the hollow portion 106 through the opening 104 and engages with the engaging portion 105 in this state. For example, the tip of the fixing member 210 is a claw portion 212, and the claw portion 212 engages with the end portion of the engaging portion 105.

  The engagement between the engaging portion 105 and the fixing member 210 is released by applying a magnetic force to the engaging portion 105 from the outside. For example, this magnetic force is applied to the engaging portion 105 by bringing the magnetic source 300 (for example, a magnet) close to the surface of the surface light source 200 opposite to the surface 202 (for example, the surface from which light is extracted). For example, the engaging portion 105 is detached from the fixing member 210 by moving by the magnetic force from the magnetic source 300.

  According to this embodiment, when the surface light source 200 is arranged on the arrangement surface 102 of the surface light source fixing device 100, the fixing member 210 enters the hollow portion 106 through the opening 104 and is mechanically engaged with the engaging portion 105. Match. Therefore, the surface light source 200 can be fixed to the surface light source fixing device 100. Further, since the engaging portion 105 is mechanically engaged with the fixing member 210, the surface light source 200 cannot be removed from the surface light source fixing device 100 unless the magnetic force source 300 is used. Accordingly, a person other than a person (for example, an operator) who knows that it is necessary to use the magnetic force source 300 to remove the surface light source 200 cannot remove the surface light source 200 from the surface light source fixing device 100.

Example 1
In the light emitting device 10 according to the present embodiment, the surface light source 200 is provided with a plurality of fixing members 210, and the surface light source fixing device 100 is provided with a plurality of hollow portions 106 and engaging portions 105.

  2A is a view of the surface light source 200 according to the first embodiment when viewed from the surface 202 side, and FIG. 2B is a cross-sectional view taken along line AA of FIG. In the present embodiment, the surface light source 200 is provided with a plurality of fixing members 210. The direction of the claw portion 212 included in at least one fixing member 210 is preferably different from the direction of the claw portion 212 included in the other fixing member 210.

  Specifically, three fixing members 210 are provided on the surface 202 of the surface light source 200. The three fixing members 210 are arranged at the vertices of, for example, an isosceles triangle or an equilateral triangle. The claw portions 212 of the two fixing members 210 are parallel to one side 203 of the surface 202 and face the direction approaching the remaining one fixing member 210. Further, the claw portions 212 of the remaining one fixing member 210 are also parallel to the side 203 and directed toward the other two claw portions 212.

  Further, the lower surface of the claw portion 212 is inclined in a direction approaching the surface 202 as it approaches the end of the claw portion 212. On the other hand, the upper surface of the claw portion 212 is parallel to the surface 202. However, the upper surface of the claw portion 212 may also be inclined in a direction approaching the surface 202 as it approaches the end of the claw portion 212.

  FIG. 3 is a plan view of the surface light source fixing device 100. A plurality of openings 104 are provided in the arrangement surface 102 of the surface light source fixing device 100. Each of the plurality of openings 104 is provided at a position corresponding to a different fixing member 210. Different hollow portions 106 are provided below the plurality of openings 104 in the surface light source fixing device 100. And the engaging part 105 is arrange | positioned in each of the some hollow part 106. FIG.

  In the example shown in the figure, the arrangement surface 102 is provided with a notation or unevenness indicating the magnet arrangement region 108. The magnet arrangement area 108 indicates an area where the magnetic force source 300 should be arranged when the surface light source 200 is removed from the surface light source fixing device 100. Thereby, when attaching the surface light source 200 to the surface light source fixing device 100, the operator can recognize the position where the magnetic force source 300 should be disposed when the surface light source 200 is removed from the surface light source fixing device 100.

  FIG. 4A is a cross-sectional view taken along the line BB in FIG. FIG. 4B is a cross-sectional view taken along the line CC of FIG. The opening 104 connects the hollow portion 106 to the outside of the surface light source fixing device 100. An engaging portion 105 is provided in the hollow portion 106.

  The engaging portion 105 includes a moving member 107. The moving member 107 engages with the fixed member 210 and moves when a magnetic force from the magnetic source 300 is applied. By this movement, the engagement between the moving member 107 and the fixed member 210 is released.

  Specifically, the moving member 107 includes a first member 110, a second member 120, and a connecting member 130. The first member 110 is movable, and the moving direction includes a component parallel to the arrangement surface 102. The second member 120 moves in a direction intersecting the arrangement surface 102 when a magnetic force from the magnetic source 300 is applied. One end side of the connecting member 130 is rotatably attached to the end portion 118 of the first member 110. The other end side of the connecting member 130 is rotatably attached to the second member 120.

  Specifically, the first member 110 is a rod-shaped member and has a hollow portion 112. The hollow portion 112 penetrates the side surface of the first member 110 and is elongated in the direction in which the first member 110 extends. A plurality of (for example, two) support shafts 114 are inserted into the hollow portion 112. The support shaft 114 is fixed to the inner wall of the hollow portion 106. In such a structure, when the support shaft 114 slides on the inner surface of the hollow portion 112, the first member 110 slides in the x direction in the figure while being supported by the support shaft 114.

  The second member 120 has a magnetic body. In this embodiment, the magnetic body is a magnet. The second member 120 is provided with a through hole 121. The through hole 121 extends in a direction (for example, a vertical direction) intersecting the arrangement surface 102. A moving shaft 122 is inserted into the through hole 121. Both ends of the moving shaft 122 are fixed to the inner surface of the hollow portion 106. In the example shown in the figure, one end of the moving shaft 122 is fixed to the upper surface of the hollow portion 106, and the other end of the moving shaft 122 is fixed to the bottom surface of the hollow portion 106. One end of a spring member 140 is attached to the second member 120. The other end of the spring member 140 is fixed to the bottom surface of the hollow portion 106. The spring member 140 urges the second member 120 in the direction toward the arrangement surface 102.

  In such a structure, the second member 120 is movable along the movement axis 122. The moving shaft 122 is provided with a stopper 124. The stopper 124 is provided to restrict the movement range of the second member 120 and is located closer to the arrangement surface 102 than the second member 120. In a state where the fixing member 210 of the surface light source 200 is not inserted from the opening 104, the second member 120 is pushed by the spring member 140 until it comes into contact with the stopper 124.

  Then, when a force is applied to the first member 110 to move the first member 110 in the direction approaching the moving shaft 122, the first member 110 moves in that direction, and the second member 120 moves to the bottom surface of the hollow portion 106. Move in the direction of approach. However, when a force that moves the second member 120 to the bottom surface of the hollow portion 106 is applied to the second member 120, the second member 120 moves in that direction, and the first member 110 approaches the moving shaft 122. Move to.

  FIG. 5 is a cross-sectional view illustrating a method for attaching the surface light source 200 to the surface light source fixing device 100 and a method for removing the surface light source 200 from the surface light source fixing device 100.

  As shown in FIG. 5A, when attaching the surface light source 200 to the surface light source fixing device 100, the operator inserts the fixing member 210 of the surface light source 200 into the opening 104 of the surface light source fixing device 100. Then, the lower surface of the claw portion 212 of the fixing member 210 contacts the one end 116 of the first member 110. Since the lower surface of the claw portion 212 is inclined, when the fixing member 210 is further pushed, one end 116 of the fixing member 210 is pushed in the direction approaching the moving shaft 122 by the lower surface of the claw portion 212 and moves in that direction. At this time, the second member 120 also moves in a direction approaching the bottom surface of the hollow portion 106 while compressing the spring member 140.

  Then, as shown in FIG. 5B, when the upper surface of the claw portion 212 of the fixing member 210 comes below the lower surface of the first member 110, a direction approaching the moving shaft 122 is added to the first member 110. Therefore, the second member 120 is pushed back by the spring member 140 in a direction approaching the placement surface 102. Accordingly, the first member 110 also moves away from the moving shaft 122, and the lower surface of the one end 116 of the first member 110 moves to the information on the upper surface of the claw portion 212. In this way, the first member 110 and the fixing member 210 are engaged, and as a result, the surface light source 200 is fixed to the arrangement surface 102.

  On the other hand, when the surface light source 200 is removed from the surface light source fixing device 100, the magnetic force source 300 is positioned above the second member 120 as shown in FIG. Here, when the magnetic force source 300 is made to repel the second member 120, the second member 120 moves toward the bottom surface of the hollow portion 106 while compressing and contracting the spring member 140. Then, the first member 110 moves in a direction approaching the moving shaft 122, whereby the one end 116 of the first member 110 is detached from the upper surface of the fixing member 210 of the surface light source 200. As a result, the fixing member 210 can be pulled out from the opening 104, and the surface light source 200 can be detached from the surface light source fixing device 100.

The detaching device 302 includes a plurality of magnetic force sources 300 and a holding unit 304. The number of magnetic force sources 300 included in the removing device 302 is the same as the number of engaging portions 105 included in the surface light source fixing device 100. The holding unit 304 holds the plurality of magnetic force sources 300 such that the relative positions of the plurality of magnetic force sources 300 are the same as the relative positions of the plurality of second members 120. Therefore, when the removal device 302 is used, the operator can easily position the plurality of magnetic force sources 300 above the plurality of second members 120, so that the surface light source 200 is removed from the surface light source fixing device 100. Can do.

  As described above, according to the present example, the same effect as the embodiment can be obtained. Moreover, the engaging part 105 can be formed only with a mechanical element.

  In the present embodiment, the magnets included in each of the plurality of second members 120 may all face the same direction, or at least one polarity may be opposite to the other. If it does in this way, people other than an operator will become difficult to remove surface light source 200 further. In this case, the polarity of the magnetic source 300 corresponding to the second member 120 having the opposite polarity among the plurality of magnetic sources 300 included in the holding unit 304 is also opposite to that of the other magnetic sources 300. Yes.

In the example shown in this drawing, in order to remove the surface light source 200 from the surface light source fixing device 100, the second member 120 may be moved to the arrangement surface 102 side. For this purpose, the magnetic source 300 may be positioned above the second member 120. At this time, when the magnetic body of the second member 120 is not a magnet, the direction of the polarity of the magnetic force source 300 may be any. On the other hand, when the magnetic body which the 2nd member 120 has is a magnet, the polarity of the magnetic source 300 is the direction which attracts this magnet.

  According to the present embodiment, the same effect as in the first embodiment can be obtained.
