Description

  The present invention relates to a straight tube lamp support that supports a straight tube lamp mounted on a luminaire body, and a lighting device.

  Conventionally, for example, as shown in FIG. 16, in the lighting device 100, a pair of sockets 102 is provided near both ends of the lighting fixture body 101. The pair of sockets 102 holds the straight tube lamp 200 in a detachable (replaceable) manner by fitting the caps 201 at both ends.

  Moreover, the lighting fixture main body 101 includes a reflector 103 for reflecting the illumination light of the straight tube lamp 200 toward the illumination target. It should be noted that a screw hole 105 is provided in advance in the central portion of the reflecting plate 103.

  However, in such an illuminating device 100, as shown in FIG. 17, the center part along the longitudinal direction which is the length of the straight tube lamp 200 is a direction away from the reflecting plate 103 with a downward apex (in FIG. 17). May be bent in the direction indicated by the arrow X in FIG.

  Such bending becomes more prominent as the size of the straight tube lamp 200 becomes longer. In addition, when the straight tube lamp 200 is an LED lamp, a large number of LED light sources and circuit boards (not shown) are mounted on the aluminum frame, and a polycarbonate transparent resin cover is provided on the aluminum frame so as to cover the LED light source. Wearing. Thereby, the bending of the transparent resin cover due to the aging deterioration accompanying the heat generation of the LED light source is more remarkable than the fluorescent lamp made of glass tube.

  Moreover, since it is common to install a plurality of lighting devices 100 on the ceiling of a building or the like, if a plurality of straight tube lamps 200 having such a deflection are arranged, problems such as poor appearance are generated. There are things to do.

  Furthermore, if such a bend occurs significantly, it means that the length of the straight tube lamp 200 is shortened with respect to the distance between the pair of sockets 102, and as a result, the pair of sockets 102 is obtained. And the fitting 201 may be loosened.

  Therefore, in order to suppress the occurrence of such bending, measures are taken such as providing a plurality of holding fixtures having spring properties in the lighting fixture body in order to hold the midway portion of the straight tube lamp 200 downward ( For example, see Patent Document 1).

  By the way, the straight tube lamp 200 is normally detachable and attached to various types of lighting fixtures (for example, a ceiling-embedded type or a ceiling-projecting type). In particular, in recent years, the diameter and cross-sectional shape of the straight tube lamp 200 are not uniform due to energy savings such as slimming of the diameter and attaching an LED lamp to an existing fluorescent lamp lighting fixture body.

  However, the holding metal fitting described in Patent Document 1 has a problem of being low in versatility because it has a specially-shaped fixing structure with respect to the luminaire main body and becomes a dedicated product. Furthermore, in the holding metal fitting described in Patent Document 1, it is possible to adjust the position along the longitudinal direction and the radial direction of the straight tube lamp in a plane parallel to the reflection plate to be attached, but in the height direction. There is also a problem that the position cannot be adjusted.

  As described above, the conventional holding bracket as described above is not only low in versatility because it is a dedicated product for the luminaire body, but also holds the straight tube lamp downward and in the height direction. Therefore, it was not possible to efficiently suppress the bending of the straight tube lamp and improve the appearance.

  The present invention has been made in view of the above circumstances, and can improve the versatility of the luminaire main body, and further enables the fine adjustment in the height direction to bend the straight tube lamp. It is an object of the present invention to provide a straight tube lamp support and an illumination device that can be efficiently suppressed and improved in appearance.

  In order to achieve the above object, a straight tube lamp support according to the present invention is a straight tube lamp support that supports a straight tube lamp between a pair of sockets provided at both ends of a luminaire body. A first support that is fixed between the sockets on the luminaire body, and a belt-like second support that engages with the first support to support the straight tube lamp from below; The second support is formed on one end side, and has a plurality of first openings having a predetermined opening area arranged at equal intervals along the longitudinal direction of the second support, and the other And a plurality of second openings arranged at equal intervals with at least one of the interval and the opening area being different from the plurality of first openings. Any one of the plurality of first openings is arranged on one side in the radial direction of the straight tube lamp. By engaging with the first support, and engaging any one of the plurality of second openings with the first support from the other radial side of the straight tube lamp, The straight tube lamp is supported from below.

  In the present invention, it is possible to improve the versatility of the luminaire main body, and to improve the appearance of the appearance by efficiently suppressing the deflection of the straight tube lamp by enabling fine adjustment in the height direction. Can do.
