Abstract

PROBLEM TO BE SOLVED: To provide a lighting device which can be easily arranged in a bathroom and is excellent in appearance.SOLUTION: In the lighting device 1 installed in the bathroom 10 having a ceiling 11 formed by at least two pieces of panels 12, 13, the lighting fixture 1 which is a linear shape and has a length equivalent to the length of the panels 12, 13 is held between the panels 12, 13 and has a lens 5 wherein the lens 5 can be adjusted at an arbitrary angle. The lens 5 is used for changing a direction of light irradiated from a light-emitting section 6. When a fluorescent lamp and a downlight are used as a light-emitting section 6, it is desirable to give directivity to light by adopting a convex lens as a lens 5. Or, when an LED lighting device is used as the light-emitting section 6, it is desirable to diffuse light by adopting a concave lens as the lens 5 since the LED lighting device is highly directive.

Description

  The present invention relates to a lighting device, and more particularly to a lighting device installed in a bathroom.

  As a lighting device installed in a bathroom, a bathroom lamp, a downlight, or the like is used. A general bathroom lamp can illuminate the entire bathroom and is excellent in workability and maintainability, but is not smart in appearance because it is projected from the ceiling or wall surface into the bathroom.

  On the other hand, a general downlight is embedded in the ceiling and has no wasteful protrusion and is excellent in appearance, but the irradiation angle is narrow and it cannot illuminate other than a specific part.

  Patent Document 1 discloses that a lighting fixture is provided at a corner between a wall surface and a ceiling in a bathroom. A long luminaire is installed horizontally along the corner, and a recess is provided in the upper end of the wall panel to embed a part of the luminaire, thereby suppressing the protrusion into the bathroom. It is said that the design can be improved.

  However, in the lighting fixture described in Patent Document 1, the volume of the lighting fixture embedded in the wall panel is about 20% of the proportion of the lighting fixture body, and most of the lighting fixture protrudes into the bathroom. It's hard to say.

  Furthermore, in order to embed the illumination fixing part in the wall panel, it is necessary to provide a recess in the wall panel. For example, it takes time to install in the existing unit bath.

  Therefore, an object of the present invention is to provide a lighting device that can be easily installed in a bathroom and has an excellent appearance.

  The invention according to claim 1 for solving the above-mentioned problem is a lighting device installed in a bathroom having a ceiling composed of at least two panels, and is sandwiched and installed between the panels. The illumination device has a length equivalent to that of the panel and includes a lens, and the lens can be adjusted to an arbitrary angle.

  In a unit bathroom, a system bath, or the like, which is a general bathroom, the ceiling is often composed of two panels because of good workability.

  The lighting device employed in the present invention is linear and has a length equivalent to that of the panel constituting the ceiling, and is sandwiched and installed between the panels. In the conventional downlight, it is necessary to pierce and embed the ceiling, but this is not necessary in this lighting device. That is, it can be easily installed and the same effect as embedding a lighting fixture in the ceiling can be obtained.

  Furthermore, the lighting device employed in the present invention includes a lens, and the lens can be adjusted to an arbitrary angle. With conventional downlights, it was impossible to illuminate other than a specific location, but this was overcome with a variable lens.

  According to the lighting device of the present invention, it can be easily installed in a bathroom and has an excellent appearance.

It is a figure which shows the illuminating device which concerns on embodiment of this invention, (a) is a front view, (b) is AA sectional drawing of (a). It is explanatory drawing which shows the attachment state of the illuminating device to the ceiling in a bathroom, (a) shows the state in which a lens is horizontal, (b) shows the state in which the lens inclined.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a lighting device of the present invention will be described in detail with reference to the drawings. In addition, the following description is for facilitating the understanding of the embodiment, and the present invention should not be understood to be limited thereby.

  The illuminating device 1 shown to Fig.1 (a) is used in the bathroom 10 mentioned later. The illumination device 1 includes a main body 2, support portions 3 and 3, packings 4 and 4, and a lens 5.

  The main body 2 is a long lighting unit, and has a length equivalent to panels 12 and 13 described later. The support portions 3 and 3 are respectively attached to the left and right sides of the substantially U-shaped main body 2. The support portions 3 and 3 hold the lens 5 from the left and right and pivotally support the lens 5 so as to be rotatable. The lens 5 is arranged in parallel with the main body 2.

  Further, packings 4 and 4 are attached to the bottom surfaces of the support portions 3 and 3. The packings 4 and 4 are conventionally known cushioning materials.

  As shown in FIG. 1B, the main body 2 has a light emitting unit 6 inside, and a drip-proof plate 7 below the light emitting unit 6. The drip-proof plate 7 is a plate member having translucency. The lens 5 is disposed opposite to the drip-proof plate 7.

  The light emission part 6 is a light source for illuminating the inside of the bathroom 10 mentioned later. It is preferable to use a conventionally known fluorescent lamp for the light emitting unit 6, and a plurality of downlights arranged in a straight line may be used. Alternatively, as the light emitting unit 6, a plurality of LED lighting devices arranged in a straight line may be used.

  The drip-proof plate 7 is a member having permeability. The drip-proof plate 7 prevents water vapor or the like from touching the light emitting unit 6 in the bathroom 10.

  The lens 5 is for changing the direction of light emitted from the light emitting unit 6. The lens 5 is made of a conventionally known acrylic or glass. As shown in FIG. 1A, the lens 5 is one long one.

  When a fluorescent lamp or a downlight is used as the light emitting unit 6, it is preferable to adopt a convex lens for the lens 5 so that the light has directivity. Alternatively, when an LED illumination device is used as the light emitting unit 6, the LED illumination device has strong directivity, and thus it is preferable to adopt a concave lens for the lens 5 to diffuse light.

  Next, the mounting state of the lighting device 1 in the bathroom 10 will be described with reference to FIGS. 2A and 2B are cross-sectional views of the panels 12 and 13 constituting the ceiling 11.

  As shown in FIG. 2A, the lighting device 1 is located at the joint 14 between the panels 12 and 13 constituting the ceiling 11. The panels 12 and 13 have rising edges 20 and 21 orthogonal to the surfaces 18 and 19, respectively. The main body 2 of the lighting device 1 is fixed to the rising edges 20 and 21 of the panels 12 and 13 with screws 15 and 16. In other words, the lighting device 1 is sandwiched and installed between the panels 12 and 13.

  The lens 5 is disposed horizontally with respect to the main body 2. The lens 5 is substantially flush with the surfaces 18 and 19 of the panels 12 and 13. When light 30 is emitted from the light emitting unit 6 in this state, light 31 is irradiated through the lens 5 parallel to the main body 2.

  On the other hand, in FIG. 2B, the lens 5 is inclined with respect to the main body 2. When light 30 is emitted from the light emitting unit 6 in this state, light 32 is irradiated through the tilted lens 5. Since the lens 5 is pivotally supported by the support portions 3 and 3 provided in the main body 2, the direction of light emitted from the light emitting portion 6 can be adjusted by adjusting the lens 5 to an arbitrary angle. It is possible to change. That is, in the bathroom 10, the light 32 can be irradiated in a direction desired by the user, such as a bathtub or a washing place (not shown).

  In the illuminating device 1 of this embodiment, although the example which makes the lens 5 one long was shown, this invention is not limited to this. For example, as the lens 5, a lens connected with a plurality of lenses may be used. In this case, the direction of each of the plurality of lenses can be freely changed, so that any part of the bathroom 1 can be irradiated simultaneously with the plurality of lenses.
