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

  As shown in FIG. 1, the illuminating device 1 includes a main light source unit 6 to which a tubular fluorescent lamp 3 is electrically connected and a secondary lamp 4 to which a disc lamp 4 in which a discharge lamp is housed is electrically connected. The light source part 7 and the support base 8 which supports each of these light source parts 6 and 7 are provided.

  The main light source 6 is disposed at the center of the support base 8 and is inserted into an electrode terminal (not shown) of the tubular fluorescent lamp 3 having an annular shape to be electrically connected to the socket (not shown). )have. The main light source unit 6 is provided with a protective cover 11 that is a glove that covers the tubular fluorescent lamp 3. An incandescent lamp (not shown) may be used for the main light source unit 6 instead of the tubular fluorescent lamp 3.

  Here, the disk-shaped lamp 4 attached to the auxiliary light source unit 7 will be described. As shown in FIGS. 2 and 3, the disk-shaped lamp 4 is electrically connected to the wound fluorescent tube 21, the lamp case 22 in which the fluorescent tube 21 is housed, and the fluorescent tube 21. And a pair of electrode pins 23. The disk-shaped lamp 4 is put to practical use mainly as a light source for indirect illumination.

  The lamp case 22 is configured in a substantially disc shape by combining a light-emitting side case 22a having light transmittance for emitting illumination light and a base side case 22b attached to a socket 15 described later of the sub light source unit 6. Yes.

  A cylindrical positioning convex portion 25 for positioning with respect to the auxiliary light source unit 7 is integrally formed on the bottom surface side of the base side case 22b. Each electrode pin 23 is disposed at a position facing each other with the positioning convex portion 25 interposed therebetween. In the lamp case 22, a circuit unit 26 for controlling the lighting of the fluorescent tube 21 is provided.

  The sub-light source parts 7 to which the disk-shaped lamps 4 are electrically connected are arranged at four positions on the outer peripheral side of the main light source part 6, and sockets 15 (for mounting the disk-shaped lamps 4 ( NEC Lighting Corporation: GX-53). The auxiliary light source unit 7 is provided with a protective cover 12 that covers the disk-shaped lamp 4.

  The socket 15 is formed with a circular positioning concave portion 31 into which the positioning convex portion 25 of the disk-shaped lamp 4 is inserted. Further, the socket 15 is provided with a set of arc-shaped engagement grooves 32 in which the respective electrode pins 23 of the disk-shaped lamp 4 are respectively engaged at positions facing each other with the positioning recess 31 interposed therebetween.

  When mounting the disk-shaped lamp 4 in the socket 15, the electrode pin 23 of the disk-shaped lamp 4 is inserted into the engaging groove 32, and the disk-shaped lamp 4 is rotated along the engaging groove 32. Thus, each electrode pin 23 is engaged with and electrically connected to the engagement groove 32, and the disk-shaped lamp 4 is supported by the socket 15.

  In the present embodiment, the disk-shaped lamp 4 is used in which the light emitting side case 22a of the lamp case 22 is formed on a flat surface, but is formed in a shape bulging outward. May be used.

  Further, as shown in FIG. 1, the auxiliary light source unit 7 may be arranged at the central portion on the inner peripheral side of the annular tubular fluorescent lamp 3 of the main light source unit 6 as required, and used as a so-called safety ball. Is made possible.

  Although not shown, the support base 8 of the lighting device 1 is an inverter for controlling the lighting of the tubular fluorescent lamp 3 mounted on the main light source unit 6 and the disk-shaped lamp 4 mounted on the auxiliary light source unit 7. A control circuit unit such as a circuit is provided.

  About the illuminating device 1 comprised as mentioned above, the various illumination states by the main light source part 6 and the sublight source part 7 are demonstrated.

  The lighting device 1 is operated by operating an infrared remote controller (not shown), for example, to turn on the main light source unit 6 only, the sub light source unit 7 on, the main light source unit 6 and the sub light source. Switching to both lighting states of the unit 7 is possible.

  The illuminating device 1 can obtain illumination light having a relatively high illuminance by the tubular fluorescent lamp 3 of the main light source unit 6 in a state where the main light source unit 6 and the sub light source unit 7 are respectively turned on. Illumination light having a relatively low illuminance by the flat lamp 4 can be obtained. And in the state where only each sub light source part 7 was turned on, for example, an environment with relatively low illuminance such as a theater room can be easily realized.

  In addition, the main light source unit 6 and each sub light source unit 7 can independently adjust the illuminance in multiple steps or in a stepless manner. In addition, the lighting device 1 can perform light reduction such that the lighting state of each sub light source unit 7 is switched from, for example, four lightings to two lightings, and the main light source unit 6 is turned off. Thus, by switching the lighting state of each sub light source unit 7, the sub light source unit 7 can be used as a so-called safety ball.

  As described above, the illumination device 1 can obtain various illumination lights by appropriately adjusting the illumination state of the main light source unit 6 and the sub light source unit 7 to adjust the light.

  In addition, the lighting device 1 is configured to be blinked or flashed by the main light source unit 6 and the sub light source unit 7 through the control circuit unit by switching to the crime prevention mode with a remote controller, for example. It is possible to enhance the sex.

  As described above, in the illumination device 1, the sub light source unit 7 includes the socket 15 to which the disk-shaped lamp 4 is mounted, so that various illumination light states can be generated by the main light source unit 6 and the sub light source unit 7. As a result, it is possible to obtain a good illumination state by the sub-light source unit 7.
