On the other hand, the light source module is formed in a long shape corresponding to the groove 12 </ b> A of the main body 12. The light source module is not particularly limited, and a straight tube fluorescent lamp unit or the like can be used, but an LED module is desirable. In the case of an LED module, an LED board (not shown) and an LED element to be mounted on the LED board are loaded therein. Moreover, this LED module is covered with a translucent cover, and this translucent cover is formed on a gentle tapered surface following the tapered portion 12 </ b> B of the main body 12, and exhibits excellent design as the lighting device 1. doing.

  Further, the shape of the LED board and the arrangement of the LED elements arranged in the LED module are not particularly limited. For example, the density of the LED elements mounted near both ends (longitudinal start and end) of the LED board. It is desirable to arrange them in a concentrated manner with a density higher than that of the LED elements arranged near the center of the LED substrate. Accordingly, it is possible to suppress a decrease in luminous intensity at both ends of the lighting device 1, and in particular, even when a plurality of lighting devices 1 are connected and continuously arranged on the ceiling surface, a connecting portion between the lighting devices 1. It is possible to suppress the decrease in the brightness of the light source, maintain the continuity of light, and ensure linear light emission.

  In addition, the LED module, and hence the LED substrate loaded in the LED module, can be formed in a flat plate shape, but in consideration of light diffusion efficiency, the LED module is formed in an inverted V shape, The LED substrate can be arranged in an inverted V shape on the slope, or the flexible LED substrate can be bent and arranged in an inverted V shape.

  In addition, since the translucent cover of the LED module is assembled by sliding from the terminal portion in the longitudinal direction of the LED module to the mounting portion of the LED substrate, it is securely fitted to the mounting portion of the LED substrate, and dropped.

Even when an unexpected pulling force is applied to 18, the pulling force is not transmitted to the connection portion between the cable 18 and the power supply board (not shown) in the box body 20, and the cable 18 is pulled from the power supply board. It can prevent peeling or disconnection. Therefore, the electrical connection of the cable 18 can be ensured while avoiding an increase in cost.

  Further, as shown in FIGS. 2 and 3, the lead-out port 28 of the cable 18 formed in the box body 20 is formed on the side of the box body 20 where the wiring fixing means 22 is provided. Therefore, as shown in FIG. 3, the cable 18 is drawn from the side closer to the side where the wiring fixing means 22 is provided than the central portion of the box body 20.

  For this reason, as shown in FIG. 3, the distance until it is fixed by the arm 24 of the wiring fixing means 22 can be shortened, so that play is eliminated and contact and interference with other electronic components, The possibility of being pulled accidentally can be avoided.

  As shown in FIG. 3, the cable 18 drawn from the box body 20 is folded and wired so as to be turned back to the box body 20 side. For this reason, the cable 18 is wired so as to crawl around the box main body 20, and the cable 18 is integrated with the box main body 20, so that there is no unnecessary play. For this reason, it is possible to prevent an unexpected pulling force from being applied to the cable 18 by, for example, pulling the cable excessively. However, the wiring of the cable 18 is not necessarily limited to the shape shown in the embodiment of FIG. 3, and the cable 18 can be wired without being folded back.

  The present invention can be widely applied to, for example, a straight-tube illumination device 10 and other illumination devices that are mainly installed on a ceiling surface of a relatively large facility such as a commercial facility such as an office or a store.
