Description

  The present invention relates to a lighting fixture attached to a ceiling surface or the like.

  2. Description of the Related Art Conventionally, lighting devices including light sources such as incandescent bulbs and fluorescent lamps have been used for indoor lighting of houses and the like. In recent years, illuminating devices using LEDs as light sources, which have characteristics such as low power consumption and long life, and can be made thinner than incandescent bulbs, fluorescent lamps, etc., have been actively developed. Yes.

  As an example of a thin luminaire, Patent Document 1 discloses a luminaire that can avoid the formation of a dark portion in a light emitting portion mainly by auxiliary components such as an infrared remote control signal receiving portion, an illuminance sensor, and a nightlight. .

  FIG. 7 is a cross-sectional view showing a mounting state of the lighting fixture on the ceiling surface related to the above-mentioned Patent Document 1, wherein 25 is a fixture body, 26 is a lighting device, 27 is a reflector, 28 is a chassis, 29 is an adapter guide, Reference numeral 30 denotes a light source unit, 31 denotes a light guide plate, 32 denotes an auxiliary component unit, 33 denotes a main body frame, and 34 denotes a cover member. The auxiliary component unit 32 includes an infrared remote control signal receiver 32a, an illuminance sensor 32b, a nightlight 32c as an auxiliary light source, and the like. A is an adapter, A1 is a locking portion A1 of the adapter A, and C is a ceiling surface. Thus, since the auxiliary component unit is disposed outside the light emitting region of the light guide plate and at the outer peripheral edge portion, it is possible to avoid forming a dark portion.

  Patent Document 2 discloses a lighting fixture in which an all-night lamp is provided at a substantially central portion of the fixture body. FIG. 8 is a side sectional view showing the luminaire, wherein 35 is a luminaire, 36 is an appliance body, 37 is a shade fixture, 38 is a shade, 39 is an annular fluorescent lamp, 40 is a remote control receiver unit, and 41 is The remote control bracket 42 is a night light. R is the minimum inner diameter of the annular fluorescent lamp.

  In this way, the nightlight is provided at the approximate center of the fixture body, and the portion from the approximate center position of the shade surface to the minimum inner diameter of the annular lamp is set as the effective irradiation range, so that the fixture for the shade when the nightlight is turned on, etc. Therefore, it is possible to prevent a shadow from being generated within the effective irradiation range of the night light.

  However, in the technique described in Patent Document 1, the nightlight is provided on the outer peripheral edge of the lighting fixture, and light is emitted from the non-center portion, so that the beauty of the irradiation light of the nightlight reflected on the shade is impaired. Even if it is going to provide a nightlight at the center of the lighting fixture, since the adapter A is engaged when the fixture main body is installed on the ceiling surface C, it is difficult to provide the nightlight at the center of the fixture main body.

  In the invention described in Patent Document 2, although the nightlight is provided at the approximate center of the lighting fixture, the nightlight is provided on the lower surface of the remote control receiver unit provided below the fixture body. The thickness of the instrument is increasing, which is a problem.

  Therefore, the present invention is to solve the above-described problems, and an object thereof is to provide a lighting fixture provided with a nightlight substantially at the center without increasing the thickness of the lighting fixture.

  The luminaire according to the present invention includes a light source, a nightlight, and a circuit board that supplies power to the light source. The luminaire includes a circuit board holder at a substantially central portion of the luminaire. The holder holds the circuit board and the nightlight lamp board, and the nightlight board is provided with a nightlight lamp.

  The nightlight substrate is held by the holding portion via a nightlight substrate cover.

  According to the luminaire according to the present invention, the nightlight can be provided substantially at the center without increasing the thickness of the luminaire.

[Example 1]
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1: has shown about the disassembled perspective view of the lighting fixture which concerns on Example 1 of this invention. 1 is a center cover, 2 is a translucent cover, 3 is a circuit board cover, 4 is a nightlight board cover, 5 is a nightlight board, 6 is a circuit board holder, and 7 is a chassis.

  The center cover 1 is made of a polycarbonate resin or the like, and is a disk-shaped resin molded product having substantially the same diameter as the engaging recess 10 provided in the translucent cover 2. Moreover, it has translucency and light diffusibility, and diffuses the light emitted from the light source and nightlight. The center cover 1 is provided with a circular hole 8 for receiving a signal from a remote controller (not shown) and a circular hole 9 for allowing ambient light to enter in order to adjust the light source. It has been.
