The case body 59 here is provided with end covers 76, 77 covering the ends of the cylindrical body 65 and the lid body 66.
The base support 63, the lid 66 and the end cover 77 are disposed at one end in the longitudinal direction, and the power supply unit 55 is disposed at the same end in the longitudinal direction.
Each part will be explained.

(1) Light Source Unit As shown in Fig. 7A, the light source unit 51 includes a plurality of LED elements 511, which are an example of light-emitting elements, and an LED board 513 on which the LED elements 511 are mounted. The LED board 513, which is an example of a light-emitting board, has a connector 515 for electrically connecting to the power supply unit 55 via a wire 519 (see Fig. 8B).

7B, the base body 53 has a light source unit holding portion that holds the light source unit 51, a power supply unit accommodating portion that accommodates the power supply unit 55, and a wireless communication unit mounting portion that mounts the wireless communication unit 57. The base body 53 here further has a base support body connecting portion for connecting to the base support body 63 and a cover body connecting portion for connecting to the cover bodies 66, 67.
7A, the base body 53 has a plate-like portion 531 and a rectangular tubular portion 537 integrally formed on the front and back sides. Here, the base body 53 is made of a metal material or a resin material, and may be, for example, an extrusion molded product.
The base body 53 here has, integrally, a pair of C-shaped portions 547 for the base support body spaced apart in the width direction, and a pair of C-shaped portions 549 for the lid body spaced apart in the width direction.
The plate-like portion 531 constitutes a light source unit holding portion and a wireless communication unit mounting portion, and the rectangular cylindrical portion 532 constitutes a power supply unit accommodating portion. The C-shaped portion 547 constitutes a base support body joining portion, and the C-shaped portion 549 constitutes a base support body joining portion and a lid body joining portion.

(2-1) Plate-Shaped Portion As shown in FIG. 7A, the plate-shaped portion 531 has a recessed portion 533 in the center in the width direction, and flat portions 535 on both sides of the recessed portion 533 in the width direction.
The width of the interior of the recessed portion 533 corresponds to the width of the LED board 513 of the light source unit 51, and the width of the opening portion is smaller than the width of the LED board 513. In this way, the LED board 513 inserted from the end in the length direction of the recessed portion 533 is supported from the front side, forming a light source unit holding portion.
The plate-like portion 531 here has folded-back portions 535a folded back in a "C" shape on both ends of the flat portion 535 in the width direction to the front side.

(2-2) Square Tube Part The square tube part 537 has a convex shape with a wider back side. In other words, the square tube part 537 has a shape with a narrow space and a wide space on the front and back inside.
The rectangular tube portion 537 has a recessed portion 533 of the plate-shaped portion 531, a pair of front wall portions 539 standing upright from both widthwise sides of the recessed portion 533, a middle wall portion 541 extending widthwise from the rear end of the front wall portion 539, a pair of rear wall portions 543 standing upright from the outer widthwise ends of the middle wall portion 541, and a rear wall portion 545 connecting the pair of rear wall portions 543.
7B, the widthwise spacing of the pair of front side wall portions 539 corresponds to the widthwise size of the power supply unit 55, and the front-back spacing between the recessed portion 533 and the rear wall portion 545 of the rectangular tubular portion 537 corresponds to the front-back size of the power supply unit 55. This forms a power supply unit accommodating portion that accommodates the power supply unit 55 inserted from the lengthwise end side of the rectangular tubular portion 537 while positioning it in the front-back and width directions.

(2-3) C-shaped portion As shown in FIG. 7A, the C-shaped portion 547 is provided at the end of the rear wall portion 543 on the middle wall portion 541 side, and the C-shaped portion 549 is provided at the connecting portion between the flat portion 535 and the front wall portion 539.
A screw 81 (see FIG. 6) that passes through the base support 63 is screwed into the C-shaped portion 547 , and a screw 83 (see FIG. 6) that passes through the covers 66 , 67 and the base support 63 is screwed into the C-shaped portion 549 .

(3) Power Supply Unit The power supply unit 55 has a power supply circuit that receives power via an external cable (see FIG. 6) 559 and generates lighting power for the light source unit 51, driving power for the wireless communication unit 57, etc. As shown in FIG. 5B, the power supply circuit is configured by mounting a plurality of electronic components 552 on a power supply board 551. Note that the power supply board 551 is provided with a connector (not shown) for connecting to the external cable 559 and a connector 553 for the wire 519 that connects to the light source unit 51. The electronic component 552 here is shown as a single block.
The power supply circuit is housed in a power supply case 554 and is housed in the rectangular cylindrical portion 537 of the base body 53. The open end of the power supply case 554 in the longitudinal direction is closed by a case lid 555.

(4) Wireless communication unit When a signal received from a lighting control device is related to the device itself, the wireless communication unit 57 transmits lighting information contained in the received signal to the power supply unit 55, and when the received signal is not related to the device itself, it transmits the received signal to other surrounding lighting devices. Note that whether or not a received signal is related to the device itself is determined by checking the received signal against identification information stored in a storage device in the dongle 577 described below.

8, the wireless communication unit 57 is detachably attached to one end of the base body 53. Note that, at one end of the base body 53, a notch 531a is provided in the plate-like portion 531 to prevent interference with the wireless communication unit 57.
As shown in Figures 9 and 10, the wireless communication unit 57 comprises a wireless base 571 for the wireless communication unit which is attached to the base body 53, a wireless module 573 supported by the wireless base 571, and a wireless cover 575 which is detachably attached to the wireless base 571 and covers the wireless module 573.
The wireless communication unit 57 here includes a dongle 577 in a wireless module 573 , in which device information of the tube lamp 5 and the like is written.

(4-1) Wireless Base The wireless base 571 has a square or rectangular shape as shown in Fig. 9(c) and Fig. 10(c). The wireless base 571 has a pair of contact portions 571a (see Fig. 11(a)) that contact a pair of flat portions 535 of the plate-shaped portion 531 of the base body 53, a connecting portion 571b that connects the pair of contact portions 571a, a base body locking portion 571c for locking the wireless base 571 to the base body 53, an attachment portion 571d for attaching the wireless cover 575, a support portion 571f that supports the wireless module 573 from the back side, and an locking portion 571g that locks the wireless module 573 from the front side.
In order to distinguish between the locking portions 571c and 571g, the locking portion 571c will be referred to as a base body locking portion 571c, and the locking portion 571g will be referred to as a board locking portion 571g.

The abutment portions 571a extend in the length direction and are provided as a pair at a distance in the width direction. As shown in FIG. 7B, when the wireless base 571 is attached to the base body 53, the abutment portions 571a are positioned in the width direction by the folded-back portion 535a of the flat portion 535 of the base body 53.
The connecting portion 571b is provided so as to recess from the inner ends in the width direction of the pair of abutting portions 571a to the front side. The connecting portion 571b has a through hole 571h for a harness 579 that electrically connects the power supply unit 55 and the wireless module 573. Since the wireless module 573 is provided with a dongle 577, the wireless base 571 has a storage portion 571j for storing the dongle 577 in the connecting portion 571b. The dongle 577 is provided on the back side of the wireless module 573, and the storage portion 571j is configured by a recessed portion that recesses from the connecting portion 571b to the back side.
Here, the through hole 571h and the housing portion 571j for the harness 579 are provided adjacent to each other. In particular, the dongle 577 is disposed in a direction in which the harness 579 is connected to the connector 573e. This increases the likelihood that the harness 579 will come into contact with the dongle 577 without coming into contact with other electronic components even if the connection operation fails when connecting the harness 579 to the connector 573e, thereby reducing damage to electronic components around the connector 573e.

The base body locking portion 571c is provided at the center of each of the contact portions 571a in the longitudinal direction, thereby allowing the wireless communication unit 57 to be attached to the base body 53 in a well-balanced manner.
The base body locking portion 571c extends rearward beyond the contact portion 571a and engages with the periphery of the through-hole 531b of the base body 53. This allows the wireless base 571 to be locked to the flat portion 535 with the contact portion 571a in contact with the flat portion 535.
The base body locking portion 571c is composed of a convex portion 571n provided at the extending tip of the extending portion 571m extending from the recessed portion 571k recessed from the contact portion 571a to the front side to the back side. The extending tip of the extending portion 571m passes through the through hole 531b of the flat portion 535 of the base body 53, so that the convex portion 571n engages with the back side of the flat portion 535. This increases the length of the extending portion 571m in the front-back direction, and increases the amount of elastic deformation of the extending portion 571m in the width direction. The width direction here is a direction perpendicular to the passing direction in which the extending tip of the extending portion 571m passes through the through hole 531b. The recessed portion 571k is also a portion that curves or bends to the front side in the same state as the thickness of the contact portion 571a.
The protruding portion 571n has an inclined surface 571p that becomes thicker as it moves away from the tip toward the front side. Due to this inclined surface and the elastically deformable configuration of the extending portion 571m, by aligning the protruding portion 571n with the through-hole 531b of the base body 53 and bringing the wireless base 571 closer to the base body 53, the extending portion 571m elastically deforms in the width direction toward the opposite side to the protruding portion 571n, and the protruding portion 571n engages with the peripheral portion of the through-hole 531b. In other words, the wireless communication unit 57 can be attached to the base body 53 without using tools or the like.

The mounting portion 571d is provided by utilizing the recessed portion 571k of the base body locking portion 571c. The mounting portion 571d is configured by a cutout portion (through hole) 571q for forming the base body locking portion 571c. The cutout portion 571q is formed in the step portion 571r between the abutment portion 571a and the connecting portion 571b, and engages with the convex portion 575d of the mounting portion 575b of the wireless cover 575.

The support portion 571f extends from the front surface of the connecting portion 571b to the front side and abuts against the back surface of the wireless board 573a of the wireless module 573. There are multiple support portions 571f, and multiple (or all) of the support portions 571f have the function of fitting into through holes in the wireless board 573a to position the wireless module 573. The back surface of the wireless board 573a is the surface of the wireless board 573a facing the wireless base 571, and the front surface is the surface opposite the wireless base 571.
The board locking portion 571 g extends from the rear surface of the connecting portion 571 b to the front surface, and locks the front surface to the wireless board 573 a of the wireless module 573 .

(4-2) Wireless Module As shown in Fig. 10C, the wireless module 573 is configured by mounting wireless antennas 573b and 573c and a wireless communication circuit 573d on a wireless board 573a. The wireless communication circuit 573d is configured with a plurality of electronic components. The wireless board 573a here is supported on the front side of the wireless base 571 in a spaced-apart state, and electronic components are mounted on both the front and back sides of the board.
The wireless antennas here are of two types: a wireless antenna 573b for long-distance communication and a wireless antenna 573c for short-distance communication.
The long-distance communication is used, for example, for communication with a lighting control device that is located farther away than the surrounding lighting devices. The short-distance communication is used, for example, for communication with surrounding lighting devices. In particular, when the lighting device 1 is installed on a platform at a station or the like, the distance to the lighting control device is large.
The long-distance wireless antenna 573b receives radio waves having a lower frequency than the short-distance wireless antenna 573c. The frequency of the received radio waves is, for example, 920 MHz for long distance communication and 2.4 GHz for short distance communication. For example, a chip antenna, a pattern antenna, etc. can be used as the antenna.
Since a lower frequency received radio wave is generally less susceptible to the effects of electromagnetic noise, here, wireless antenna 573b for long-distance communication is disposed in a position close to LED board 513, which is a source of electromagnetic noise, and wireless antenna 573c for short-distance communication is disposed in a position far from LED board 513. Note that wireless antennas 573b and 573c are disposed on the back surface of wireless board 573a.

The wireless communication circuit 573d is composed of a microcomputer equipped with a CPU, RAM, ROM, etc. The CPU of the wireless communication circuit 573d collates received signals based on programs and data stored in the ROM, rewrites identification information in the storage device in the dongle 577, transmits lighting information included in the received signals to the power supply unit 55, and transmits received signals to other lighting devices 1.
An existing protocol or an independently developed protocol may be used for communication with the lighting control device or other lighting devices 1. Examples of existing protocols that can be used include Bluetooth (registered trademark), ZigBee (registered trademark), WiFi (registered trademark), ANT (registered trademark), Wi-SUN (registered trademark), Z-wave (registered trademark), WirelessHART (registered trademark), and EnOcean (registered trademark).

11A, the wireless board 573a is supported on the front side relative to the light source unit 51. This makes the wireless communication circuit 573d less susceptible to the effects of electromagnetic noise generated by the LED board 513.
As shown in FIG. 5B, the wireless board 573a is arranged parallel to the LED board 513 and does not overlap in the front-back direction. This makes the wireless communication circuit 573d less susceptible to the effects of electromagnetic noise generated by the LED board 513. This also makes it possible to reduce the thickness of the straight tube lamp 5 in the front-back direction. Note that "parallel" here means that the inclination angle of the main surface of the LED board 513 with respect to the main surface of the wireless board 573a is within the range of 0 to 10 degrees (including 0 degrees and 10 degrees).
The wireless board 573a has wireless antennas 573b and 573c on its back surface, and a portion on the front surface that is located on the front side of the wireless antennas 573b and 573c is a passing region 573g. The passing region 573g is, for example, a region where a conductive path that constitutes a conductive pattern is not formed. The passing region 573g is also a region where electronic components, etc. are not mounted or are arranged. This makes it easier for radio waves for wireless communication to pass through the wireless board 573a.

As shown in Figures 9 and 10, the wireless module 573 is connected to the power supply unit 55 by a harness 579, and receives power and outputs signals for lighting conditions. The wireless board 573a has a connector 573e for the harness 579, with its connection port facing outward in the width direction. As a result, as shown in Figure 9 (b), the connection side end of the harness 579 curves so as to protrude outward in the width direction and passes through the through hole 571h of the wireless base 571, making it difficult for the harness 579 to come off the connector 573e. Since the harness 579 is led out from the back side of the wireless communication unit 57, it does not appear as a shadow on the cylindrical body 65 of the case body 59 when the light is on.

The dongle 577 is provided so as to stand from the back surface of the wireless board 573a toward the inside of the cutout portion 531a (see FIG. 8) of the base body 53. This allows the thickness of the straight tube lamp 5 in the front-to-back direction to be thin. In addition, the protrusion of the wireless communication unit 57 toward the front side based on the front surface of the LED board 513 can be reduced, and blocking of the light from the LED element 511 can be suppressed.
5B, the power supply unit 55 is disposed longitudinally inside the cutout 531a of the base body 53 and adjacent to the wireless communication unit 57. This allows the harness 579 electrically connecting the power supply unit 55 and the wireless communication unit 57 to be shortened, and the dimensions of the straight tube lamp 5 in the front-to-back direction to be reduced.

(4-3) Wireless Cover The wireless cover 575, as shown in FIGS. 9 and 10, has a box-shaped main body 575a with an open back side, and an attachment portion 575b for detachably attaching the wireless cover 575 to the wireless base 571.
As shown in Fig. 10, the mounting portion 575b is composed of a convex portion 575d provided on the inner surface of a long side wall portion 575c along the length direction of the main body portion 575a, and groove portions 575f on both sides of the convex portion 575d. As shown in Fig. 11(b), the convex portion 575d engages with the mounting portion 571d by utilizing a cut portion 571q of the wireless base 571. At this time, since the groove portions 575f are provided on both sides of the convex portion 575d, the convex portion 575d can be elastically deformed in the width direction when the convex portion 575d engages.
11B, when the wireless cover 575 is attached to the wireless base 571, the attachment portion 575b is located inside in the width direction with respect to the base body locking portion 571c of the wireless base 571. As a result, the attachment portion 575b is protected by the base body locking portion 571c of the wireless base 571.

(5) Base Support Body The common configuration of the base supports 62, 63 will be described first, and then the different configurations will be described individually.
