The straight tube lamp 11 in which the lamp pin 28 and the ground pin 29 are inserted into the groove of the rotor 32 is rotated by 90 ° about the tube axis, so that the lamp pin 28 and the ground pin 29 are connected to the socket. It is connected to a terminal in the main body 31. In FIG. 1, the configuration of the sockets 13a and 13b is omitted, but terminals and the like are arranged inside the sockets 13a and 13b.

  Further, the tube 14 is formed in a cylindrical shape with a material such as transparent glass or synthetic resin such as polycarbonate.

  The support means 15 includes an attachment cylinder 41 that is an outer cylinder, and a ring 42 and an inner cylinder 43 that are arranged inside the attachment cylinder 41.

  The mounting cylinder 41 is formed in a cylindrical shape, an inner diameter insertion hole 44 through which the tube 14 can be inserted is formed on one end side, and the inner peripheral surface on the other end side is a peripheral surface of the mounting portion 34 of the socket body 31 A female screw 45 is formed to be screwed onto the male screw 35 provided on the head. An annular packing 46 is disposed between the attachment portion 34 and the other end of the attachment cylinder 41. In addition, an inclined surface 47 whose diameter decreases toward the center of the insertion hole 44 is formed at the peripheral edge of the insertion hole 44.

  The ring 42 is formed in an annular shape from an elastic material such as rubber or silicone resin, and has a function as a packing. The inner diameter of the ring 42 is close to the outer diameter of the tube 14 and can be fitted to the outer periphery of the tube 14. The ring 42 is disposed between the inclined surface 47 of the mounting cylinder 41 and the inner cylinder 43.

  The inner cylinder 43 is formed in a cylindrical shape through which the tube 14 can be inserted, and a pressing portion 48 that contacts the ring 42 is formed on one end side. When the mounting cylinder 41 is attached to the socket body 31, the inner cylinder 43 abuts on the sockets 13a and 13b, and the ring 42 is pushed between the pressing portion 48 of the inner cylinder 43 and the inclined surface 47 of the mounting cylinder 41. It can be crushed.

  The dimensional relationship of the tube 14 will be described. For example, the diameter d1 of the translucent cover 21 that is the arc tube portion of the straight tube lamp 11 is about 24.8 mm, and the diameter d2 of the caps 23a and 23b is about 26.5 mm. , The inner diameter d3 of the tube 14 is about 29 mm, the outer diameter d4 is about 27.4 mm, and the straight tube lamp 11 can be inserted inside the tube 14.

  Further, as shown in FIG. 3, the length L1 of the tube 14 is shorter than the total length L2 of the straight tube lamp 11 (the length between the outer end surfaces of the caps 23a and 23b). The length L3 of the optical cover 21, the length L4 between the rings 42 of the support means 15 attached to the sockets 13a and 13b, the surface of the rotor 32 of one of the sockets 13a and 13b and the sockets 13a and 13b Each is set longer than the distance L5 between the ring 42 of the support means 15 attached to the other.

  Next, the operation of the illumination device 10 will be described.

  The installation of the straight tube lamp 11 will be described. First, the straight tube lamp 11 is inserted into the inside of the tube 14, and the support means 15 that combines the mounting tube 41, the ring 42, and the inner tube 43 is fitted from both ends of the tube 14. And is inserted through the tube 14. At this time, the support means 15 is arranged at a position closer to the center than the end of the tube 14 so that the support means 15 does not hide the caps 23a, 23b of the straight tube lamp 11.

  By inserting the lamp pin 28 and the ground pin 29 protruding from the caps 23a and 23b of the straight tube lamp 11 from the tip side of the sockets 13a and 13b, the straight tube lamp 11 is arranged between the sockets 13a and 13b, The straight tube lamp 11 is rotated by 90 °, and the straight tube lamp 11 is mounted at predetermined mounting positions of the sockets 13a and 13b. When the straight tube lamp 11 is rotated by 90 °, for example, the tube 14 is offset to the socket 13b side, and the end of the tube 14 is brought into contact with the rotor 32 of the socket 13b. Since 23a is exposed, the straight tube lamp 11 can be easily rotated by holding the base 23a with an operator's finger. The same applies when the tube 14 is offset toward the socket 13a.

  The support means 15 inserted through both ends of the tube 14 is moved toward the sockets 13a and 13b, and the female screw 45 of the mounting cylinder 41 is screwed to the male screw 35 of the mounting portion 34. During the screwing, the inner cylinder 43 abuts against the sockets 13a and 13b and the movement is restricted. Therefore, the inclined surface 47 of the mounting cylinder 41 that moves toward the sockets 13a and 13b and the inner cylinder 43 that is restricted from moving. The ring 42 is crushed between the pressing portion 48 and the ring 42 bulges in the inner diameter direction and the outer diameter direction. The ring 42 that bulges in the inner diameter direction contacts the outer peripheral surface of the tube 14 and presses with an equal pressing force from the entire periphery.

  As a result, the sockets 13a and 13b are positioned and held via the ring 42 of the support means 15. Since the straight tube lamp 11 is attached to the sockets 13a and 13b at a predetermined mounting position, the positional relationship between the straight tube lamp 11 and the tube 14 is also positioned through the sockets 13a and 13b. That is, the tube axis of the straight tube lamp 11 and the center of the tube 14 coincide, and the outer peripheral surface of the straight tube lamp 11 and the inner peripheral surface of the tube 14 are opposed to each other with a uniform gap over the entire circumference. Is done.

  Further, the length L1 of the tube 14 is greater than the distance L5 between the surface of the rotor 32 of one of the sockets 13a and 13b and the ring 42 of the support means 15 attached to the other of the sockets 13a and 13b. Since the tube 14 is set to be long, the support attached to the other of the sockets 13a and 13b is supported even if the tube 14 is offset so as to contact the surface of the rotor 32 of either of the sockets 13a and 13b. The tube 14 is not detached from the ring 42 of the means 15, and the tube 14 can be supported by the ring 42.

  When the tube 14 is made of glass, the straight tube lamp 11 having the synthetic resin translucent cover 21 is covered with the glass tube 14. Can be configured.

  Further, since the packing 46 interposed between the socket main body 31 and the mounting cylinder 41 and the ring 42 interposed between the tube 14 and the mounting cylinder 41 are provided, the waterproof illumination device 10 can be configured.

  Further, by using a color tube colored on the tube 14, illumination of a desired color can be obtained, and can be used for various uses such as a crime prevention light, a clean room light, and a low insect light. In this case, the tube 14 may be formed of any material of glass and synthetic resin.

  According to the above embodiment, the straight tube lamp 11 can be configured to be covered with the tube 14. Moreover, the tube 14 can be supported at a predetermined position with respect to the sockets 13a and 13b via the mounting cylinder 41 and the ring 42 of the support means 15. Furthermore, by making the length of the tube 14 shorter than the total length of the straight tube lamp 11, the straight tube lamp 11 can be attached to and detached from the sockets 13a and 13b, and operability can be ensured.

  In the case where the straight tube lamp 11 has a relatively long overall length, the straight tube lamp 11 having both ends supported by the pair of sockets 13a and 13b may be bent so that the intermediate portion thereof is lowered. In such a case, the inner surface of the tube 14 that covers the straight tube lamp 11 can support the lower surface side of the intermediate portion that is bent downward of the straight tube lamp 11, and due to the bending applied to the straight tube lamp 11. The load can be reduced.

  Next, FIG. 6 shows a second embodiment. In addition, about the same structure as 1st Embodiment, the description is abbreviate | omitted using the same code | symbol.

  In order to prevent the end of the tube 14 from cracking and cracking from the end of the glass tube 14, heat treatment is performed to melt and round the end of the tube 14. Along with this heat treatment, a restricting portion 51 that protrudes toward the inner diameter side is formed at the end of the tube 14.

  In this case, the length L1 of the tube 14 is shorter than the length L3 of the translucent cover 21 of the straight tube lamp 11. The inner diameter d5 of the restricting portion 51 is set larger than the diameter d1 of the translucent cover 21 of the straight tube lamp 11 and smaller than the diameter d2 of the caps 23a and 23b.

  In this embodiment, when the straight tube lamp 11 is assembled, the translucent cover 21 is inserted into the tube 14 and then the caps 23 a and 23 b are attached to both ends of the translucent cover 21. Thereby, the tube 14 is not detached from the straight tube lamp 11, and the tube 14 is temporarily fixed to the straight tube lamp 11.

  Then, the support means 15 is attached to both ends of the straight tube lamp 11, the straight tube lamp 11 is disposed between the sockets 13a and 13b, and each support means 15 is attached to the sockets 13a and 13b, so that the ring 42 is straight. The tube 14 is supported by contacting the outer peripheral surface of the tube 14 temporarily fixed to the tube lamp 11.

  As described above, since the tube 14 is temporarily fixed to the straight tube lamp 11, when the straight tube lamp 11 is mounted, the operation of passing the straight tube lamp 11 through the tube 14 and the tube 14 are avoided. , 23b is not required to be rotated and the straight tube lamp 11 can be mounted more easily.

  The straight tube lamp 11 is not limited to a straight tube lamp using a semiconductor light emitting element, but may be a straight tube discharge lamp.

  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.
