  However, if the light emitting element modules are arranged in two or more rows so as to face in the same direction, the positions of the connection connectors of the respective light emitting element modules become two or more rows. There is a risk of wiring on the module board.

  Therefore, in consideration of wiring, it is conceivable to arrange the light emitting element modules in a straight line, but in that case, the lighting device becomes longer and the wiring becomes longer. When the wiring becomes longer, the influence of voltage drop or the like is likely to occur.

  An object of the present invention is to provide a light-emitting element module and an illumination device that can easily perform wiring between light-emitting element modules when arranging a plurality of light-emitting element modules side by side, and can shorten the wiring.

  A light-emitting element module according to a first aspect of the present invention includes a rectangular planar substrate; a plurality of semiconductor light-emitting elements disposed on the substrate; provided at both ends of one side of the substrate; A connection connector in which a terminal connected to the substrate is arranged in an outward direction parallel to one side of the substrate; power is supplied in series to the plurality of semiconductor light emitting elements formed on the substrate between the terminals of the connection connector; And a conductor to be provided.

  A quadrangle includes a square and a rectangle. It is preferably a square, but is not limited thereto.

  The semiconductor light emitting elements arranged on the substrate may be arranged so as to be distributed almost evenly on the substrate, for example. “Distributing substantially evenly” means that the surface density when a plurality of semiconductor light emitting elements are distributed on the substrate is arranged substantially uniformly. The semiconductor light emitting device includes a light emitting diode (LED), an organic light emitting diode (OLED), and a light emitting polymer (LEP). “An outward direction parallel to one side of the substrate” refers to a direction away from the substrate in a direction parallel to one side of the substrate. The terminals arranged in this way are connected from the outside of the substrate with power supply lines, connection lines, short-circuit lines and the like connected to the connection connectors parallel to one side.

  A lighting device according to a second aspect of the present invention is characterized in that the light emitting element modules according to the first aspect are arranged in one or more rows in two columns so that the connection connectors face each other.

  “Connecting connectors face each other” means that the connecting connectors face each other and become adjacent to each other. For example, when one pair of adjacent light emitting element modules is arranged so that the sides face each other and the connection connectors face each other, the connection connectors are arranged so that the terminals of the adjacent light emitting element modules face each other. May be arranged such that the one pair of light emitting element modules is combined so that the connection connectors face each other.

  According to the first aspect of the present invention, the connection connectors are provided at both ends of one side of the board, and the terminals connected to the power source or the other board are arranged in the outward direction in parallel with one side of the board. When arranging a plurality of light emitting element modules linearly in the column direction, the terminals of the connector are simply connected to each other. Therefore, the wiring is short and the connection can be made very easily.

  According to the invention of claim 2, since the light emitting element modules are arranged in one row or a plurality of rows in two columns so that the connection connectors face each other, it is possible to connect with a short wiring when distributing and wiring from the power supply unit. .

  FIG. 1 is a configuration diagram of a light emitting element module 10 according to an embodiment of the present invention. The substrate 11 of the light emitting element module 10 is formed in a rectangular planar shape. In FIG. 1, the case where it forms in the square is shown. A plurality of semiconductor light emitting elements 12 are arranged on the substrate 11 so as to be almost evenly distributed. In FIG. 1, a total of 16 semiconductor light emitting elements 12 are arranged, 4 in the vertical direction and 4 in the horizontal direction.

  Then, connection connectors 13a1 and 13a2 are provided on either one side of the substrate 11, and on both ends of the right side in FIG. The connection connectors 13a1 and 13a2 have terminals 14a1 and 14a2, respectively, and the terminals 14a1 and 14a2 are connected to a power source or a terminal of another board. Further, the terminals 14a1 and 14a2 are arranged in an outward direction of one side (right side) of the substrate 11 (a direction parallel to the right side and away from the substrate 11). This facilitates connection with a power source or a terminal of another substrate.

  Conductors 15 and 16 are connected between the terminal 14a1 of the connection connector 13a1 and the terminal 14a2 of the connection connector 13a2. The conductor 15 is a conductor that connects a plurality of semiconductor light emitting elements 11 attached to the substrate 11 in series, and the conductive wire 16 is a conductor that directly connects the terminal 14a1 of the connection connector 13a1 and the terminal 14a2 of the connection connector 13a2. is there.

  Now, assuming that the terminal 14a2 of the connection connector 13a2 is short-circuited and a power source is connected between the terminals 14a1 of the connection connector 13a1, the current from the power source flows through each semiconductor light emitting element 11 connected in series through the conductor 15, The power returns to the power source through the conductor 16 via the short-circuit portion of the terminal 14a2 of the connection connector 13a2.

  As described above, the light emitting element module 10 is provided with the connection connectors 13a1 and 13a2 at both ends of one side of the substrate 11, and the terminals connected to the power source or another substrate are parallel to one side of the substrate 11 in the outward direction. Therefore, when the plurality of light emitting element modules 10 are linearly arranged in the column direction, the terminals 13a1 and 13a2 of the connection connector need only be connected to each other. Further, since the terminals are arranged close to each other, the wiring for connecting the terminals is short, and the connection can be made very easily. Since the wiring is shortened, the voltage drop of the wiring can be prevented and the illuminance can also be prevented from decreasing.

  FIG. 2 is a configuration diagram of the illumination device according to the embodiment of the present invention. The lighting device is configured by arranging a plurality of light emitting element modules 10 shown in FIG. FIG. 2 shows a case where four light emitting element modules 10a to 10d are arranged in two columns and two rows. The light emitting element modules 10a and 10c form the first row, the light emitting element modules 10b and 10d form the second row, and the first row light emitting element modules 10a and 10c are the second row light emitting element module 10b. 10d are arranged so that one side faces each other and the connection connector 13 faces. That is, the connection connectors 13a1 and 13a2 of the light emitting element module 10a in the first row face the connection connectors 13b1 and 13b2 of the light emitting element module 10b, and the connection connectors 13c1 and 13c2 of the light emitting element module 10c in the second row are light emitting elements. It faces the connection connectors 13d1, 13d2 of the module 10d.

  Here, in order to face and arrange the connection connector 13 of the light emitting element module 10 shown in FIG. 1, when the light emitting element module 10 shown in FIG. 1 is rotated 180 degrees, the light emitting element module 10b shown in FIG. 10d.

  Next, the terminal 14a2 of the connection connector 13a2 of the light emitting element module 10a in the first row is connected to the terminal 14c1 of the connection connector 13c1 of the light emitting element module 10c, and the terminal 14c2 of the connection connector 13c2 of the light emitting element module 10c is short-circuited. To do. Thereafter, a power source is connected between the terminals 14a1 of the connection connector 13a1 of the light emitting element module 10a. Accordingly, the semiconductor light emitting elements 12 of the light emitting element modules 10a and 10c in the first column are connected in series, and power is supplied from the power source.

  Similarly, the terminal 14b2 of the connection connector 13b2 of the light emitting element module 10b in the second row is connected to the terminal 14d1 of the connection connector 13d1 of the light emitting element module 10d, and the terminal 14c2 of the connection connector 13d2 of the light emitting element module 10d is short-circuited. To do. Thereafter, a power source is connected between the terminals 14b1 of the connection connector 13b1 of the light emitting element module 10b. Thereby, the semiconductor light emitting elements 12 of the light emitting element modules 10b and 10d in the second row are connected in series, and power is supplied from the power source.

  Thus, the light emitting element modules 10 are arranged in one row or a plurality of rows in two columns, and the connection connectors 13 are arranged so as to face each other, so that the wiring location is located at the center of the plurality of light emitting element modules 10. As a result, the connection positions of the power supply lines are close to each other, and wiring to the power supply becomes easy. Further, wiring between the light emitting element modules 10 can be easily performed, and the wiring length can be shortened. Therefore, the influence of voltage drop or the like is less likely to occur.
