  For example, when the LED 14b is a blue LED chip, a silicone resin containing YAG (yttrium, aluminum, garnet) -based yellow phosphor particles is used as the sealing member 14c. Accordingly, since the yellow phosphor particles are excited by the blue light of the blue LED chip to emit yellow light, white light is emitted from the sealing member 14c by the excited yellow light and the blue light of the blue LED chip. Is done. The sealing member 14c may include a light diffusing material such as silica.

  The connecting member 33 has a connection terminal electrically connected to each of the power supply circuit 40 and the power feeding terminal. According to such a connection terminal, the connecting member 33 not only mechanically connects the first light source unit 10 and the second light source unit 20 but also connects the first light source unit 10 and the second light source unit 20 to one power source. Light can be emitted by power feeding from the circuit 40.

  Specifically, the connection terminals are the first negative terminal 12c and the second connection terminal 33b that is electrically connected to the negative output terminal 40b of the power supply circuit 40.

  The second connection terminal 33b is electrically connected to the first negative electrode terminal 12c by directly contacting the first negative electrode terminal 12c.

This circuit can be simplified. For example, the first light source unit 10 and the second light source unit 20 can emit light by feeding from one power supply circuit 40. If it does so, a circuit structure can be simplified rather than the circuit structure which requires a power supply circuit in each of the 1st light source part 10 and the 2nd light source part 20.

Thus, the connection member 33 included in the lighting device 100a includes the first positive terminal 12b and the first connection terminal 33a that is electrically connected to the positive output terminal 40a of the power supply circuit 40 as the connection terminal.

  The first connection terminal 33a is electrically connected to the first positive electrode terminal 12b by directly contacting the first positive electrode terminal 12b.

  Thereby, if the 2nd negative electrode terminal 23c is electrically connected to the negative output terminal 40b, the 1st light source part 10 and the 2nd light source part 20 will be connected in series with respect to the one power supply circuit 40. FIG. If it does so, the illuminating device 100a can light-emit the 1st light source part 10 and the 2nd light source part 20 by the electric power feeding from the one power supply circuit 40. FIG.
