  In FIG. 7, the lamp device A and the fixture A, the lamp device B and the fixture B, the lamp device C and the fixture C, the lamp device D and the fixture D, and the lamp device E and the fixture E depend on the light output of the lamp devices A to E, respectively. The heat radiation amount and the heat radiation performance of the appliances A to E are optimal combinations.
  The lamp devices A to E can be mounted on any of the instruments A to E. When the lamp devices A to E are combined with an optimal combination of fixtures A to E and fixtures having higher heat dissipation performance than the fixtures A to E, power is supplied from the fixtures to the lamp devices A to E.

In addition, when the lamp devices B to E are combined with fixtures A to D having lower heat dissipation performance than the optimal fixtures B to E, power is not supplied from the fixtures A to D to the lamp devices B to E. The lamp devices B to E do not light up.
  For example, when the lamp device C is combined with the fixture C, the amount of heat released by the light output of the lamp device C and the heat dissipation performance of the fixture C are optimized. In this case, the negative pole of the power supply circuit 13 is electrically connected to the light source 21 through the first terminal 77 of the # 1 of the socket 14 and the first electrode 40 of the # 1 of the lamp device C.

It is electrically connected to the light source 21 through the second electrode 41, DC power is supplied to the light source 21, and the light source 21 is turned on. In this case, the lamp device C can be used only with the excessive heat dissipation performance of the fixture E with respect to the amount of heat generated according to the light output of the lamp device C.
  As shown in FIGS. 5 (b) and 7, when the lamp device C is combined with the fixture D having higher heat dissipation performance than the fixture C, the negative pole of the power supply circuit 13 is the first terminal of the socket # 1. 77 and the first electrode 40 of the lamp device C # 1 are electrically connected to the light source 21, and the positive pole of the power supply circuit 13 is connected to the second terminal 78 of the socket # 5 and the # 5 of the lamp device C.

In this case, the lamp device C can be used only with the excessive heat dissipation performance of the fixture D with respect to the amount of heat generated according to the light output of the lamp device C.
  As shown in FIGS. 5 (c) and 7, when the lamp device C is combined with the fixture B having a lower heat dissipation performance than the fixture C, the negative pole of the power supply circuit 13 is the first terminal of the socket # 1. 77 and the # 1 first electrode 40 of the lamp device C, and the positive pole of the power supply circuit 13 is connected to the second terminal 78 of # 3 of the socket 14 and the second electrode 41 of # 3 of the lamp device C. Although connected, the # 3 second electrode 41 is not electrically connected to the light source 21, so no DC power is supplied to the light source 21 and the light source 21 is not lit. In this combination, if DC power is supplied to the lamp device C, the heat dissipation performance of the fixture E is insufficient with respect to the amount of heat generated according to the light output of the lamp device C, and the lamp device C is thermally affected. It will occur.
  Similarly, FIGS. 6 (a) and 6 (b) show a case where the lamp device B is combined with fixtures E and D having higher heat dissipation performance than the fixture B, and direct current power is supplied to the light source 21 of the lamp device B. The light source 21 is turned on. FIG. 6 (c) shows a case where the lamp device B is combined with an appliance B that has the optimum heat dissipation performance. DC power is supplied to the light source 21 of the lamp device B, and the light source 21 is turned on.
  Thus, according to the present embodiment, it is possible to supply power to the light source 21 from any of at least two or more second electrodes 41 that are electrically connected to the light source 21 of the lamp device 11. Therefore, the lamp device 11 can be used in common if the fixture 12 has the best heat dissipation performance or the fixture 12 has a higher heat dissipation performance than the fixture 12 with the best heat dissipation performance.
  Furthermore, since the lamp device 11 includes the second electrode 41 that is not electrically connected to the light source 21, when the lamp device 11 is mounted on the fixture 12 having a lower heat dissipation performance than the fixture 12, the second electrode 41 is provided.

In the instrument H, the second power output part 67 of the power circuit 13 and the # 5 second terminal 78 of the socket 14 are electrically connected. In the appliance I, the second power output portion 67 of the power circuit 13 and the second terminal 78 of # 6 of the socket 14 are electrically connected. Therefore, in the appliances F to I, the terminals 71 arranged at different positions of the socket body 70 according to the heat radiation performance are electrically connected to the power supply circuit 13 as the second terminals 78.
  The lamp device F and the fixture F, the lamp device G and the fixture G, the lamp device H and the fixture H, the lamp device I and the fixture I are respectively radiated by the light output of the lamp devices F to I and the heat dissipation of the fixtures F to I. It is a combination that optimizes performance.
  The lamp devices F to I can be mounted on any of the instruments F to I. When the lamp apparatus F to I is combined with an optimal combination of the apparatuses F to I and an apparatus having a higher heat dissipation performance than the apparatuses F to I, the lamp apparatus F to I is supplied with power, and the lamp apparatus F to I are lit. In addition, when the lamp devices G to I are combined with the optimal fixtures G to I which have lower heat dissipation performance than the fixtures F to H, power is not supplied from the fixtures F to H to the lamp devices G to I. The lamp devices G to I are not lit.
  Next, FIG. 13 shows a third embodiment. In addition, about the structure and effect | action similar to 1st Embodiment, the description is abbreviate | omitted using the same code | symbol.
  An example in which the lamp devices A and C having one light source 21 and the lamp devices F, G, H, and I having two light sources 21 and the appliances F, G, H, and I are mixed and combined is shown.
  The lamp devices A and F and the fixture F, the lamp devices C and G and the fixture G, the lamp device H and the fixture H, the lamp device I and the fixture I are respectively radiated by the light output of the lamp devices F to I and the fixtures F to I. The heat dissipation performance is an optimal combination.
  The lamp devices A, C, F to I can be mounted on any of the instruments F to I. When the lamp devices A, C, F to I are combined with an optimal combination of the devices F to I and a device with higher heat dissipation performance than the devices F to I, the lamp devices A, C, F to Power is supplied to I, and the lamp devices A, C, F to I are lit. In addition, when the lamp devices C and G to I are combined with an optimal combination of fixtures G to I, the lamp devices C and G to I are not supplied with power, and the lamp devices C and G to I are not supplied with power. Devices C and G to I are not lit.
  Note that the configuration of the present embodiment is not limited to the form of the lamp device 11 and the socket 14 described above, but can be applied to lamp devices and sockets of other forms.
  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
