Description

  The present invention relates to a power feeding device and a surface light source.

  In recent years, a technique for using a surface light source such as an organic EL (Organic Electroluminescence) element and an LED (Light Emitting Diode) as a light source of a lighting device has been developed. One method of using these surface light sources is to attach the surface light source to a surface such as a wall surface or a ceiling.

  In Patent Document 1, it is described in the power generation apparatus that a shielding means for suppressing an operator from touching a terminal for supplying power to a load is used. In this technique, the shielding means shields the terminal when the terminal is separated from the load, and exposes the terminal to the outside when the terminal is connected to the load. This shielding means has a pushing member pushed by the terminal when the load approaches the terminal. When the pushing member is pushed, the terminal moves to the load side.

FIG. It is a figure which shows the modification of FIG.

  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 includes a power supply device 100 and a surface light source 200. The surface light source 200 has a surface light source such as an organic EL element or LED. The surface light source 200 has a plate shape or a sheet shape. The surface light source 200 is arranged on the arrangement surface 102 of the power supply apparatus 100. Further, a power source terminal 210 is provided on the surface of the surface light source 200 that faces the arrangement surface 102.

  An arrangement surface 102 of the power supply apparatus 100 is provided in the surface light source holding unit 101. The power supply apparatus 100 includes a power supply unit 111, a storage unit 106, and a moving unit 105 in addition to the arrangement surface 102 described above. The power supply unit 111 supplies electricity to the surface light source 200. Specifically, the power supply unit 111 is connected to the power supply terminal 210 of the surface light source 200. The accommodating part 106 accommodates the electric power feeding part 111 inside. Then, when the surface light source 200 is arranged on the arrangement surface 102, the moving unit 105 moves the power supply unit 111 from the accommodation unit 106 toward the arrangement surface 102 and connects it to the power supply terminal 210 of the surface light source 200. The moving unit 105 has, for example, a mechanical structure. When a part of the structure is pressed by the surface light source 200, the moving unit 105 directs the power feeding unit 111 toward the surface light source 200. Convert to moving force. Note that a specific structure of the moving unit 105 will be described later using an embodiment.

  According to the present embodiment, the power feeding unit 111 is located in the housing unit 106 until the surface light source 200 is arranged on the arrangement surface 102. Therefore, when the worker attaches the light emitting device 10 to a surface such as a wall surface or a ceiling, the worker can be prevented from touching the power supply unit 111 by mistake.

Example 1
2 and 3 are diagrams illustrating the configuration of the light emitting device 10 according to the first embodiment. FIG. 2 is a diagram before the surface light source 200 is mounted on the arrangement surface 102, and FIG. 3 is a diagram illustrating a state where the surface light source 200 is mounted on the arrangement surface 102. In the light emitting device 10 shown in these drawings, the moving unit 105 of the power feeding device 100 includes an insulator member 110, a rotating shaft 120, and a contact member 130.

  The lever member 110 and the rotating shaft 120 are provided inside the surface light source holding unit 101. The rotating shaft 120 supports the lever member 110 rotatably. That is, the lever member 110 rotates about the rotating shaft 120 as a rotating shaft. And the power feeding part 111 is provided in the one end side of the insulator member 110 so that it may contact | connect. In the example shown in this figure, the insulator member 110 extends linearly except for the end portions. The power feeding unit 111 is one end of the lever member 110.

  Note that an opening 107 is provided in a region of the arrangement surface 102 located above the power feeding unit 111. In a state where the surface light source 200 is arranged on the arrangement surface 102, the opening 107 faces the power supply terminal 210. For this reason, when the lever member 110 rotates, the power feeding unit 111 can jump out of the opening 107 and be connected to the power supply terminal 210.

  One end side of the abutting member 130 protrudes outside through the opening 104 provided in the arrangement surface 102, and is movable toward the inside of the surface light source holding unit 101. The other end of the contact member 130 is in contact with the other end of the lever member 110 from the arrangement surface 102 side. The contact member 130 is, for example, a pin-shaped member, but may have a shape other than the pin. When the surface light source 200 is disposed on the arrangement surface 102, the contact member 130 is pushed toward the inside of the surface light source holding unit 101 by the surface light source 200. Then, the lever member 110 rotates around the rotation shaft 120, and as a result, the power feeding unit 111 is pushed out of the housing unit 106.

  In the present embodiment, the power supply apparatus 100 includes a power supply terminal 140 and a wiring 150. The wiring 150 connects an external power supply to the power supply terminal 140. The power terminal 140 is connected to the power receiving unit 113 provided in the lever member 110 in a state where the power feeding unit 111 is pushed out of the housing unit 106. The power receiving unit 113 and the power feeding unit 111 are connected to each other via a conductive member provided on the lever member 110. This conductive member may be formed on the surface of the insulator member 110 or may be the insulator member 110 itself. In the latter case, the insulator member 110 is made of a conductive material (for example, a metal such as copper). In the example shown in the figure, the power receiving unit 113 is provided at the end of the lever member 110 opposite to the power feeding unit 111. However, the position of the power receiving unit 113 is not limited to the example shown in this figure.

  In this way, unless the surface light source 200 is arranged on the arrangement surface 102, no voltage is applied to the power feeding unit 111.

  The moving unit 105 has a spring member 160. The spring member 160 is attached to a portion of the lever member 110 that is different from the rotating shaft 120, and biases the lever member 110 in a direction in which the power feeding unit 111 is housed inside the housing unit 106. In the example shown in the drawing, one end of the spring member 160 is attached to the lever member 110 on the side closer to the power feeding unit 111 than the rotating shaft 120. Further, the other end of the spring member 160 is attached to a surface on the opposite side to the arrangement surface 102 among the inner surface of the accommodating portion hollow portion 106, that is, the bottom surface. When the power feeding unit 111 is connected to the power supply terminal 210, the spring member 160 is in an extended state. However, the spring member 160 may be attached to the lever member 110 in a direction farther from the power feeding unit 111 than the rotating shaft 120. In this case, when the power feeding unit 111 is connected to the power supply terminal 210, the spring member 160 is in a contracted state.

  In this way, when the surface light source 200 is removed from the arrangement surface 102, the power feeding unit 111 is housed inside the housing unit 106 by the spring member 160.

  4 is a perspective view of the power supply apparatus 100 as viewed from the arrangement surface 102 side, and FIG. 5 is a perspective view of the surface light source 200 as viewed from the surface side where the power supply terminal 210 is provided.

  As shown in FIG. 4, the power supply apparatus 100 includes two sets of a lever member 110, a rotating shaft 120, a contact member 130, a power supply terminal 140, a wiring 150, and a spring member 160. One set is provided for supplying a power supply voltage to the surface light source 200, and the other set is provided for supplying a ground voltage to the surface light source 200.

  Correspondingly, as shown in FIG. 5, the surface light source 200 is provided with two power terminals 210. One power supply terminal 210 is supplied with a power supply voltage, and the other power supply terminal 210 is supplied with a ground voltage.

  According to this embodiment, when the surface light source 200 is disposed on the arrangement surface 102, the contact member 130 is pushed into the surface light source holding unit 101 by the surface light source 200. Then, the lever member 110 rotates around the rotation shaft 120, and the power feeding unit 111 is pushed out of the surface light source holding unit 101 through the opening 107. Thereby, the power feeding unit 111 is connected to the power supply terminal 210 of the surface light source 200. For this reason, the power supply terminal 210 is located in the accommodating part 106 until the surface light source 200 is arrange | positioned on the arrangement | positioning surface 102. FIG. Therefore, when the worker attaches the light emitting device 10 to a surface such as a wall surface or a ceiling, the worker can be prevented from touching the power supply unit 111 by mistake.

(Example 2)
FIG. 6 is a diagram illustrating a configuration of the light emitting device 10 according to the second embodiment. FIG. 7 is a diagram illustrating a state in which the surface light source 200 is arranged on the arrangement surface 102 of the power supply apparatus 100 illustrated in FIG. 6. The power supply apparatus 100 according to the present embodiment has the same configuration as that of the power supply apparatus 100 according to the first embodiment, except that the lever member 110 is bent around the rotation shaft 120.

  Specifically, the insulator member 110 is bent in a direction in which the power receiving unit 113 approaches the arrangement surface 102. Accordingly, the position of the surface of the power supply terminal 140 that contacts the power receiving unit 113 is also approaching the arrangement surface 102.

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

Example 3
FIG. 8 is a diagram illustrating a configuration of the light emitting device 10 according to the third embodiment. The light emitting device 10 according to the present embodiment has the same configuration as the light emitting device 10 according to Example 1 or Example 2 except for the following points.

  First, the contact member 130 is not provided in the power feeding apparatus 100. Instead, a convex mounting portion 222 is provided on the surface of the main body of the surface light source 200 on which the power terminal 210 is provided. The convex mounting part 222 is a structure for detachably mounting the convex part 220. The convex mounting portion 222 is a groove in which a female screw is formed, for example. And when attaching the surface light source 200 to the electric power feeder 100, the convex part 220 is attached to the convex part attaching part 222. FIG.

  When the surface light source 200 is arranged on the arrangement surface 102, the convex part 220 enters the inside of the surface light source holding part 101 through the opening 104. The convex part 220 acts on the moving part 105 and moves the power feeding part 111 from the accommodating part 106 to the outside of the arrangement surface 102. Specifically, the tip of the convex portion 220 abuts on a portion (for example, the power receiving portion 113) of the lever member 110 on the opposite side to the power feeding portion 111 via the rotating shaft 120 and pushes down this portion. Thereby, the lever member 110 rotates around the rotating shaft 120, and as a result, the power feeding unit 111 is connected to the power supply terminal 210 of the surface light source 200.

  According to the present embodiment, the same effect as that of the first or second embodiment can be obtained. Moreover, the convex part 220 of the surface light source 200 is removable. Therefore, until the surface light source 200 is installed, the surface light source 200 remains in a sheet shape or a plate shape. Therefore, the surface light source 200 can be easily transported.

  In the present embodiment, the convex portion 220 may be fixed to the main body of the surface light source 200. Even if it does in this way, the effect similar to Example 1 or Example 2 will be acquired.

  As shown in FIG. 9, the abutting member 130 may be provided on the lever member 110. In this case, the convex part 220 rotates the lever member 110 by pushing down the contact member 130. In the example shown in the drawing, the upper end of the contact member 130 does not have to jump out of the arrangement surface 102.

  As mentioned above, although embodiment and the Example were described with reference to drawings, these are illustrations of this invention and can also employ | adopt various structures other than the above.
