As shown in FIG. 21, the illustrated wireless communication section 63 has an internal substrate 631 , a plurality of communication components 632 and a cover 633 . The internal board 631 is a wiring board on which a plurality of communication components 632 are mounted. Further, the internal substrate 631 may partially include an antenna for wireless communication. A plurality of communication components 632 are components that constitute a wireless communication circuit for performing wireless communication. The cover 633 accommodates the internal board 631 and the plurality of communication components 632 and protects them. Cover 633 is made of resin, for example.

Also, the height of the cover 633 in the z direction is set to be slightly lower than or substantially the same as the height of the opening 6121 in the z direction. This prevents the surface of the cover 633 from protruding from the opening 6121 and prevents the cover 633 from interfering with obstacles outside the opening 6121 .

Connector 66 is used, for example, to electrically connect wireless communication module 6 and power supply unit 3 . The connector 66 is mounted on the communication board 62 and is connected with a cable (not shown). This cable is connected to the power supply unit 3, for example.

The screw 69 is for fixing the first part 611 and the second part 612 . In the illustrated example, the screw 69 is passed through the threaded column 6126 of the second part 612 and screwed into the threaded column 6113 of the first part 611 .

As shown in FIG. 20 , when attaching the base 7 to the case 61 , the engaging portion 6115 of the first portion 611 and the engaging portion 6124 of the second portion 612 are engaged with the engaging portion 711 . Also, the recess 712 engages with a rib 6114 shown in FIG. 18 when the base 7 is attached to the case 61 .

<Clasp 8>
The base 8 is attached to the end of the cover 4 opposite to the human sensor module 5 or the wireless communication module 6 in the x direction, as shown in FIGS. The base 8 is paired with the base 7, and is used to attach the LED lighting device A1 to a power supply section such as a socket. Note that depending on the specifications of the lighting equipment to which the LED lighting device A1 is attached and the specifications of the base 7 and the power supply unit 3, the base 8 performs only a mechanical attachment function to the socket and does not contribute to electrical connection. It may be a configuration.

Next, the operation of the LED lighting device A1 will be described.

According to this embodiment, as shown in FIG. 22, either the human sensor module 5 or the wireless communication module 6 can be selectively attached to the end of the cover 4 in the x direction. For this reason, components other than the human sensor module 5 and the wireless communication module 6, such as the support member 1, the LED 2, the power supply unit 3, the cover 4 and the base 8, are made common, and the human sensor corresponding to the first module and the second module is made common. By attaching either the sensor module 5 or the wireless communication module 6, it is possible to realize LED illumination devices A1 having different functions. For this reason, if the support member 1, the LED 2, the power supply unit 3, the cover 4, the base 8, etc., which are common, the human sensor module 5 and the wireless communication module 6 are prepared in advance, then any combination can be made. The LED lighting device A1 can be manufactured by assembling the above. Therefore, it is possible to more easily achieve high functionality and diversification of the LED lighting device A1. One of the human sensor module 5 and the wireless communication module 6 and the cover 4 may be fixed using an adhesive or the like, or may be detachable using an engagement or screw. good.

The human sensor module 5 and the wireless communication module 6 each have a base 7 with common specifications. As a result, it is possible to more efficiently configure modules that perform different functions, such as the human sensor module 5 that performs the human body detection function and the wireless communication module 6 that performs the wireless communication function. This is preferable for improving the manufacturing efficiency and reducing the cost of the LED lighting device A1.

As shown in FIG. 9, in the human sensor module 5, the case 51 is provided with ribs 5114, and the recesses 712 of the mouthpiece body 71 of the mouthpiece 7 shown in FIG. 18, in the wireless communication module 6, the case 61 is provided with ribs 6114, and the recesses 712 of the mouthpiece main body 71 of the mouthpiece 7 shown in FIG. As a result, regardless of whether the base 7 is attached to the case 51 or the case 61, the base 7 may be unduly displaced from either the human sensor module 5 or the wireless communication module 6 (z installation by rotating around the direction) can be avoided.

FIG. 23 shows another embodiment of the invention. In these figures, the same or similar elements as in the above embodiment are denoted by the same reference numerals as in the above embodiment.

<Second embodiment>
FIG. 23 is an exploded perspective view showing an LED lighting device A2 according to the second embodiment of the invention. In the LED lighting device A2 of this embodiment, the cover 4A and the cover 4B having different lengths are prepared, and either one is selected and attached to the human sensor module 5. FIG. Note that the cover 4A and the cover 4B are not limited to the human sensor module 5, and may be configured to be attached to the wireless communication module 6 or the like.

The covers 4A and 4B have different lengths. The cover 4A corresponds to, for example, a 40-type, which indicates the tube length of a straight tube fluorescent lamp, and the cover 4B corresponds to a 20-type. In addition, in this embodiment, the support member 1, the LED substrate 21, the plurality of 22, the power source section 3, and the like are appropriately configured corresponding to the length of the cover 4A and the cover 4B.
