  Next, attachment of the lighting device to the ceiling will be described. 6 and 7 are cross-sectional views schematically showing the lighting device in which the locking angle 4 is locked to the T-bar, and FIG. 8 is a partial cross-sectional view schematically showing the lighting device in which the hook 10 is hooked on the T-bar.

  The ceiling is composed of a plurality of adjacent ceiling panels 100, and a plurality of T bars 80, 80, ..., 80 extending in the horizontal direction are provided in the ceiling so as to be orthogonal to each other. The T-bar 80 is formed at a rail-like base portion 81 extending in the horizontal direction, an upper end portion of the base portion 81, a head portion 82 having a narrow width in the horizontal direction, and a lower end portion of the base portion 81. And a foot 83 having a wide width in the horizontal direction. The lower part of the foot part 83 is flush with the ceiling panel 100.

  As shown in FIG. 7, the vertical dimension of the base part 81 and the foot part 83 is substantially the same as the width (vertical dimension) of the side surface part 1b. Further, as shown in FIG. 8, the vertical dimension of the base part 81 and the foot part 83 is substantially the same as the width (vertical dimension) of the side frame 1c. The vertical dimension of the head 82 is substantially the same as the vertical dimension of the third plate part 13 of the hook 10, and the horizontal dimension of the head 82 is approximately half of the horizontal dimension of the second plate part 12 of the hook 10. The dimension between the other surface part 4 b of the locking angle 4 and the translucent cover 7 is substantially the same as the vertical dimension of the foot part 83.

  When attaching the lighting device to the ceiling, an operator first removes one ceiling panel 100. An operator arrange | positions an illuminating device in a ceiling in the state which turned the translucent cover 7 downward from the opening formed by removing the one ceiling panel 100. FIG. Next, the operator hooks the curved portion of the hook 10 to the head 82 and locks the other surface portion 4 b of the locking angle 4 to the foot portion 83. At this time, the other surface portion 4b of the locking angle 4 closes the clearance between the T bar 80 and the side surface portion 1b and the clearance between the T bar 80 and the side frame 1c (see FIGS. 7 and 8). Further, the second plate portion 12 comes into contact with the head portion 82, the translucent cover 7 and the ceiling panel 100 are substantially flush with each other, and most of the lighting device is located in the ceiling panel 100.

  Then, the operator inserts the wire into the wire hole 1cb, and connects the frame in the ceiling and the lighting device via the wire. Further, the operator connects the conducting wire connected to the external device to the dimming terminals 8e and 9e in the opening 1d formed in the frame 1, and connects the conducting wire connected to the commercial power supply to the power supply terminals 8d and 9d.

  In the lighting device according to the embodiment, since the frame 1 includes the opening 1d, a lead wire connected to an external device is inserted into the opening 1d and connected to the dimming terminals 8e and 9e and the power supply terminals 8d and 9d. Connection work can be completed in a short time.

  Further, since the dimming terminals 8e and 9e and the power supply terminals 8d and 9d are arranged toward the opening 1d, the operator can connect the lead wires to the respective terminals in the space in the opening 1d.

  Further, since the terminal is provided on the opening 1d side of the power supply unit, the operator can easily connect the lead wires to the light control terminals 8e and 9e and the power supply terminals 8d and 9d by putting their hands in the opening 1d.

  Further, by providing the hook 10 on the protruding portion 1ca, the hook 10 is positioned on the other surface side of the support plate portion 1a, that is, on the first power supply unit 8 or second power supply unit 9 side. Further, the vertical dimension of the base part 81 and the foot part 83 and the width (vertical dimension) of the side part 1b are made substantially the same, and the vertical dimension of the base part 81 and the foot part 83 and the width (vertical dimension) of the side frame 1c are made substantially the same. ing. Furthermore, the vertical dimension of the head 82 is substantially the same as the vertical dimension of the third plate portion 13 of the hook 10. Therefore, when the LED 51 is on the lower side and the hook 10 is hooked on the T-bar 80 and the illuminating device is attached to the ceiling, most of the illuminating device enters the ceiling panel 100, and the illuminating device is almost from the ceiling panel 100. The translucent cover 7 does not protrude and is substantially flush with the ceiling panel 100. As a result, an impression that the lighting device and the ceiling panel 100 are united is brought about, and the interior property of the lighting device can be improved.

  When the holding member that holds the translucent cover 7 is provided on the entire periphery of the translucent cover 7, the holding member is visually recognized by the user, but the lighting device according to the embodiment includes the holding piece 2 and Since the translucent cover 7 is held between the side surface portion 1b and the holding piece 2 is small and cannot be visually recognized, the appearance design is improved.

  Further, since the curved portion of the hook 10 is hooked on the head 82, the lighting device does not come off the T-bar 80 even if an object comes into contact with the lighting device attached to the ceiling from below. The lighting device can be removed from the ceiling by releasing the bolting between the hook 10 and the side frame 1c and removing the hook 10 from the side frame 1c.

  Further, since the other surface portion 4b of the locking angle 4 closes the gap between the T bar 80 and the side surface portion 1b and the gap between the T bar 80 and the side frame 1c, the appearance design of the lighting device is improved.

  In addition, by using the LED 51 as a light source, the amount of heat generation and power consumption can be suppressed as compared to a fluorescent tube and an incandescent bulb.

  In addition, although the illuminating device which concerns on embodiment is provided with two power supply units, the structure provided with one power supply unit may be sufficient. In this case, the power supply unit is configured to control driving of the first LED 51a and the second LED 51b. Moreover, although the illuminating device which concerns on embodiment is provided with 1st LED51a light-emitted by the daylight color close | similar to white, and 2nd LED51b light-emitted by the light bulb color close | similar to orange, you may provide LED provided with a different color further. In this case, it goes without saying that the driving of the LEDs is controlled for each color by one or a plurality of power supply units.

  In the display device according to the embodiment, the first LEDs 51a and the second LEDs 51b are arranged linearly across the two substrates 50, and are arranged alternately, but in a staggered arrangement as shown in FIG. There may be. Moreover, although the illuminating device which concerns on embodiment uses LED as a light source, it may replace with LED and may use LD (Laser Diode), EL (Electro-Luminescence), etc. as a light source.

  The above embodiment is an example of the present invention, and it goes without saying that the present invention can be implemented in variously modified forms within the scope of the matters described in the claims.
