  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  1 and 2 show an LED lighting device according to a first embodiment of the present invention. The LED lighting device 101 of this embodiment includes a straight tube LED lamp 201, a base 300, two sockets 401 and 402, and a replacement prevention member 600. The LED lighting device 101 is a lighting device in which a straight tube LED lamp 201 is used instead of a general straight tube fluorescent lamp.

  The straight tube type LED lamp 201 includes a substrate 210, a plurality of LED chips 220, a heat radiating member 230, a cover 240, and two bases 250, and has an elongated cylindrical shape.

  The substrate 210 has a long rectangular shape with the axial direction of the straight tube LED lamp 201 as the longitudinal direction, and has, for example, a base material made of glass epoxy resin and a wiring pattern formed on the base material. The base material preferably has an insulating surface, and may be composed of, for example, aluminum covered with ceramics or an insulating film.

  The plurality of LED chips 220 are light sources of the straight tube LED lamp 201, and include a plurality of semiconductor layers made of, for example, a GaN-based semiconductor. The LED chip 220 is, for example, a bare chip type that is directly mounted on the substrate 210. In this case, the LED chip 220 is covered with, for example, a fluorescent resin (not shown). When the LED chip 220 emits blue light, for example, the fluorescent resin is made of a material in which a transparent material that is excited by blue light and emits yellow light is mixed. As a result, the straight tube LED lamp 201 emits white light. The LED chip 220 is not limited to the bare chip type, and includes, for example, a case that covers the LED chip 220, the fluorescent resin that is filled in the case and covers the LED chip 220, and a mounting terminal that is electrically connected to the LED chip 220. It may be a packaged LED module. The plurality of LED chips 220 are arranged, for example, along the longitudinal direction of the substrate 210.

  The heat radiating member 230 is made of a metal such as aluminum, and is bonded to the substrate 210. The heat dissipating member 230 is used for efficiently dissipating heat from the plurality of LED chips 220.

  The cover 240 is tubular and is made of, for example, milky white translucent resin. The cover 240 accommodates the substrate 210, the plurality of LED chips 220, and the heat dissipation member 230.

  The two caps 250 are disposed at both ends of the cover 240 in the longitudinal direction. Each base 250 is provided with two rod-shaped terminals (not shown). All or one of these terminals is electrically connected to the wiring pattern of the substrate 210. The two caps 250 have the same shape and size as the caps of general straight tube fluorescent lamps.

  The base part 300 is a part for attaching the straight tube LED lamp 201 to a ceiling or the like, and is made of, for example, metal or resin. In the present embodiment, the base part 300 has a rectangular parallelepiped shape in which the axial direction of the straight tube LED lamp 201 is the longitudinal direction. Mounting openings 321 and 322 are formed in the base portion 300. The attachment opening 321 corresponds to the first attachment opening referred to in the present invention, and the attachment opening 322 corresponds to the second attachment opening referred to in the present invention. The mounting openings 321 and 322 are spaced apart in a direction perpendicular to the longitudinal direction of the straight tube LED lamp 201.

  The two sockets 401 and 402 are spaced apart at positions near both ends in the longitudinal direction of the base part 300. The two sockets 401 and 402 are portions into which the two caps 250 of the straight tube LED lamp 201 are loaded, and have shapes and sizes that can be loaded with the caps of general straight tube fluorescent lamps. The sockets 401 and 402 incorporate a mechanism that can appropriately load and remove the base 250. For example, a mechanism is employed that prevents the removal by rotating the straight tube LED lamp 201 after the terminal of the base 250 is slid and inserted from a certain direction. Or the mechanism which implement | achieves loading and removal by providing the site | part which can be advanced / retracted using the elastic force in one of the sockets 401 and 402 is employ | adopted.

  The replacement blocking member 600 is for preventing the straight tube LED lamp 201 from being erroneously replaced with a general straight tube fluorescent lamp, for example. In the present embodiment, the replacement prevention member 600 includes a support portion 611, leg portions 621 and 622, and fixing portions 631 and 632. The replacement preventing member 600 is preferably made of a metal wire. As a material of the replacement prevention member 600, for example, a resin wire or a band-shaped member made of metal or the like can be appropriately adopted in addition to the metal wire.

  The support portion 611 is a portion that supports the straight tube LED lamp 201 from the opposite side of the base portion 300, and corresponds to the first support portion referred to in the present invention. Preferably, the support portion 611 is in contact with the straight tube LED lamp 201, but in order to achieve the purpose of preventing the replacement of the straight tube LED lamp 201, it is not necessarily in contact with the straight tube LED lamp 201. There is no need, and there may be a gap between the straight tube type LED lamp 201. In the present embodiment, the support portion 611 is in contact with the base 250 of the straight tube LED lamp 201.

  The two leg portions 621 and 622 are connected to both ends of the support portion 611. The leg 621 corresponds to the first leg referred to in the present invention, and the leg 622 corresponds to the second leg referred to in the present invention. In the present embodiment, the two leg portions 621 and 622 are configured not to intersect with each other in the longitudinal direction of the straight tube LED lamp 201, and are separated from both the left and right sides of the straight tube LED lamp 201 in FIG. Are arranged.

  The two fixing parts 631 and 632 are provided at the tips of the two leg parts 621 and 622. The fixing portion 631 corresponds to a first fixing portion referred to in the present invention, and the fixing portion 632 corresponds to a second fixing portion referred to in the present invention. The fixing portion 631 is fixed to the attachment opening 321 of the base portion 300, and the fixing portion 632 is fixed to the attachment opening 322. In the present embodiment, both of the fixing portions 631 and 632 are configured such that the end portions of the replacement preventing member 600 are bent in an annular shape. In the present embodiment, the fixing portions 631 and 632 are both fixed to the mounting openings 321 and 322 by rivets 691. The rivet 691 has a narrow-diameter portion inserted through the mounting openings 321 and 322 and the fixing portions 631 and 632 and two relatively large-diameter heads disposed at both ends of the small-diameter portion. These heads are larger than the opening dimensions of the mounting openings 321 and 322. The opening size of the attachment openings 321 and 322 means, for example, the diameter when the attachment openings 321 and 322 are circular, and means the length of one side when the attachment openings 321 and 322 are square.

  Next, the operation of the LED lighting device 101 will be described.

  According to the present embodiment, the straight tube LED lamp 201 is restrained by the base portion 300 by the replacement preventing member 600. This prevents the straight tube LED lamp 201 from being detached from the sockets 401 and 402. Therefore, it is possible to prevent the straight tube LED lamp 201 from being accidentally removed.

  By engaging the rivet 691 with the attachment opening 321, the fixing portion 631 can be firmly fixed by the attachment opening 321. Similarly, by engaging the rivet 691 with the mounting opening 322, the fixing portion 632 can be firmly fixed by the mounting opening 322.

  By bringing the support portion 611 close to the base 250, it is possible to prevent the replacement preventing member 600 from improperly blocking the light from the cover 240.
