Description

  The present invention relates to a luminaire that is installed separately by attaching an attachment member to a ceiling or a wall surface.

  There are various types of lighting fixtures, such as pendant lights, stands, and bracket lights. A luminaire embedded in the ceiling is referred to as a downlight. The downlight is bright immediately under illumination, but is embedded in the ceiling, so that the light does not spread around the ceiling surface, so the ceiling surface around the lighting fixture is relatively dark.

For example, although the lighting fixture of patent document 1 is a ceiling light, it also radiates | emits light also to a side and a back direction.
Specifically, in the lighting fixture of Patent Document 1, a translucent cover is provided on the fixture body in which the semiconductor light emitting element is disposed so as to cover the front surface and the side surface of the semiconductor light emitting element, and from the semiconductor light emitting element. There is provided a light control body that emits emitted light from the peripheral portion of the translucent cover toward the side and back of the instrument body.

JP 2010-140797 A

  The lighting fixture described in Patent Document 1 emits light in the back direction, but even if the light from the semiconductor light emitting element is reflected by the light control body, the light only spreads to the side, and the back side of the fixture body. The direction cannot be illuminated because the instrument body gets in the way. However, since the lighting fixture of patent document 1 is a ceiling light arrange | positioned on a ceiling surface without a gap, even if the back side of a lighting fixture is not illuminated, there is no problem.

  About this point, in the lighting fixture installed in the state away from the ceiling surface and the wall surface by interposing the mounting member which installs the device body between the ceiling surface and the wall surface, There is a space between them. For this reason, in order to illuminate the ceiling surface or wall surface, it is necessary to emit light obliquely backward rather than laterally, so that light from the light source is difficult to reach. In particular, in a lighting fixture having a reflector for reflecting light from the light source forward, the reflector and the casing surrounding the reflector illuminate the light from the light source to the side and back. Can not do it.

  Such a luminaire is bright because the front is irradiated with light, but the surroundings of the luminaire and the back direction (rear) are darkened, so that only a function as a spotlight can be provided.

  Therefore, an object of the present invention is to provide a lighting device that is easy to use by being able to illuminate the front side and also illuminate the back direction.

  The lighting fixture of the present invention includes a fixture main body in which a light source is arranged, and an attachment member for installing the fixture main body away from an installation location, and the fixture main body has an opening as it goes forward from the light source. A first reflecting portion on which a spreading reflecting surface is formed; a second reflecting portion that reflects light from the light source in a back direction; and an outer side of the first reflecting portion, and the second reflecting portion. And a casing that transmits light from the housing.

  According to the lighting fixture of the present invention, the light forward from the light source is directed to the front without being reflected by the first reflective part or by being reflected by the first reflective part. Moreover, the light reflected by the 2nd reflection part goes to a back direction. The light traveling in the back direction has a housing portion that surrounds the outside of the first reflecting portion. However, since the housing portion transmits light from the second reflecting portion, the housing portion passes through the housing portion and passes through the back surface. It can be advanced in the direction.

  When the second reflecting portion is a reflecting surface formed outside the first reflecting portion, the light reflecting toward the outside is reflected without being reflected by the first reflecting portion and is directed toward the back surface. Therefore, it is possible to prevent obstructing the light that is reflected by the first reflecting portion and travels forward, or the light that travels straight and forward.

  If a gap is formed between the first reflecting portion and the light source so that light directed to the side of the light source is allowed to pass through the housing portion, the light toward the side of the light source is formed. Moreover, since it can be made to radiate | emit from the housing | casing part of an instrument main body, without being disturbed by the 1st reflection part, the range which light spreads can be made wide.

  If the casing portion contains a coloring material that colors the light of the light source, the casing can be colored with the light from the light source, so that various effects can be created.

  If a connecting member that connects the housing part and the housing part of another lighting fixture is provided, when the amount of light is insufficient, the connecting member can be connected to another lighting fixture to increase the lighting fixture. it can.

  According to the present invention, since it can pass through the housing portion and travel in the back direction, it is possible to provide a lighting device that is easy to use by being able to illuminate the back direction while firmly illuminating the front.

A lighting apparatus according to an embodiment of the present invention will be described with reference to the drawings. In the present specification, when the lighting fixture is installed on the ceiling surface, the direction directly below the light source is referred to as the front, and the opposite is referred to as the back direction or the rear.
As shown in FIGS. 1 to 5, the lighting fixture 10 is attached to a ceiling surface, a wall surface, or a stand leg if indoors, or attached to an arm member for illuminating a signboard from below if outdoor. It is something that is. The lighting fixture 10 includes a fixture body 20, an attachment member 30, and a heat dissipation member 40.

  As shown in FIG. 1, the instrument main body 20 includes a light emitting substrate 21 serving as a light source, a first reflecting portion 22 disposed in front of the light emitting substrate 21, and a light reflecting from the light emitting element 21 a in the back direction. 2, a housing part 24 that surrounds the outside of the first reflecting part 22, and a front cover 25 that covers the front part of the housing part 24.

  In the light emitting substrate 21, four light emitting elements 21a that emit white light are mounted on a printed wiring board 21b. The light emitting element 21a can be an LED element or another element. Further, the light emitting element 21a can be a warm color system or emit various color temperatures in addition to white. Although the number of the light emitting elements 21a is four in FIG. 1, it may be 1 to 3 or 5 or more. Furthermore, as long as the light emitting substrate 21 functions as a light source, the light emitting substrate 21 can be a light bulb or a fluorescent lamp, in addition to a substrate in which an LED element is mounted.

The first reflecting portion 22 is a reflecting plate that is formed in a rectangular shape when viewed from the opening side on the emission side and has a funnel shape in which the opening expands toward the front. The first reflecting portion 22 can be made of metal or resin. In the present embodiment, the first reflecting portion 22 is formed with a step portion 22a on an inclined surface between the incident side opening and the emission side opening that surrounds the light emitting element 21a. As shown in FIGS. 3 and 5, since the opening on the emission side of the first reflecting portion 22 is formed slightly smaller than the opening of the housing portion 24, the first reflecting portion 22 includes the housing portion 24. Protruding portions 22b for fixing to the both ends of the opening on the emission side are formed.
As shown in FIG. 1, a gap 22 c is formed between the first reflecting portion 22 and the light emitting substrate 21.

As shown in FIG. 6, the second reflecting portion 23 has a reflecting surface 23a in which a lower end portion (one end portion on the front side) is formed in a straight line and an upper end portion (the other end portion) is formed in an arc shape. doing. As shown in FIG. 5, the second reflecting portion 23 is located in front of the opening edge of the first reflecting portion 22 corresponding to each corner portion of the casing portion 24 formed in a rectangular shape. In this case, it is disposed outside the first reflecting portion 22 at a position where the gap 22d is formed between the first reflecting portion 22 and the housing portion 24.
When the light from the light emitting element 21a or the light reflected on the first reflecting portion 22 reaches the reflecting surface 23a, the light is reflected not only on the reflecting surface 23a but toward the back surface, It can also be directed to the protruding portion 22b of the reflecting portion 22.

  As shown in FIGS. 1 and 2, the light emitting substrate 21 and the heat radiating member 40 are mounted on the base end portion of the housing portion 24. As shown in FIGS. 1 and 4, the casing portion 24 is formed with a flange portion 24 a that extends horizontally at an opening edge portion that becomes a tip portion. The front cover 25 is fixed to the flange 24a by screwing. The housing | casing part 24 is formed with the member which has a light transmittance. For example, the casing 24 can be formed of glass or the like in addition to a resin material such as polycarbonate or acrylic.

  As shown in FIGS. 1 and 3, the front cover 25 is a lid that closes the opening formed by the first reflecting portion 22 and the housing portion 24. The front cover 25 is formed of a light transmissive member. For example, the front cover 25 can be formed of polycarbonate, acrylic, glass, or the like, similar to the case portion 24. On the front cover 25, a bowl-shaped uneven portion 25a for diffusing light from the light emitting element 21a is formed so as to surround the center portion. The peripheral edge portion 25b of the front cover 25 is combined with the flange portion 24a of the housing portion 24, and a screw hole for screwing is formed.

As shown in FIGS. 1, 2, and 4, the attachment member 30 is a member for attaching to a ceiling surface, a wall surface, a stand leg, or an arm member. The attachment member 30 is interposed between the frame portion 31 formed in a U-shape, and between the frame portion 31 and the housing portion 24, and the frame portion 31 is screwed to both ends in the longitudinal direction of the housing portion 24. It is provided with a fixing member 32 for stopping.
The heat dissipating member 40 is a heat sink in which heat dissipating fins are arranged on the back side of the light emitting substrate 21 opposite to the mounting surface of the printed wiring board 21b with the housing portion 24 interposed therebetween.

A use state of the lighting fixture 10 according to the embodiment of the present invention configured as described above will be described with reference to the drawings. In the present embodiment, it is assumed that the lighting fixture 10 is installed on the ceiling surface C by the attachment member 30.
As shown in FIG. 7, when power is supplied to the light emitting substrate 21, the light emitting element 21a is turned on. The light from the light emitting element 21a is not reflected by the first reflecting portion 22, but is directly reflected by the light (not shown) directed to the front of the lighting fixture 10 and by the first reflecting portion 22, and thereby the lighting fixture. The lower part is brightly illuminated by the light (indicated by the optical path F1) heading 10 forward.

  Of the light traveling from the light emitting element 21 a toward the opening edge of the first reflecting portion 22, the light traveling toward the corner portion is reflected by the second reflecting portion 23. The light reflected by the second reflecting portion 23 travels in the back direction (backward) or obliquely rearward, and passes through the gap 22d between the first reflecting portion 22 and the housing portion 24. A casing 24 surrounds the first reflecting portion 22 outside the first reflecting portion 22. However, since the housing | casing part 24 is formed with the member which has a light transmittance, it does not inhibit the signal of light. The light transmitted through the casing portion 24 illuminates the back direction, travels through the space with the ceiling surface C formed by the mounting member 30, and illuminates the ceiling surface C brightly (indicated by an optical path F2).

  Thus, since the lighting fixture 10 can illuminate the front side and can also illuminate in the back direction, it can be installed in various places as an easy-to-use lighting fixture. In addition, the lighting fixture 10 is not only bright in the front, but the ceiling surface C is also brightened, so that the apparent size of the lighting fixture 10 can be shown larger.

  Moreover, since the 2nd reflection part 23 is formed in the outer side of the 1st reflection part 22, the light which goes outside is not reflected in the 1st reflection part 22, but is directed to the back direction. Therefore, it is possible to prevent obstructing the light that is reflected by the first reflecting portion 22 and travels forward, or the light that travels straight and forward.

  Further, the light reflected by the second reflecting portion 23 is reflected to the side as well as the light traveling in the back direction. The light reflected laterally from the second reflecting portion 23 illuminates the protruding portion 22b of the first reflecting portion 22 and the side surface of the fixing member 32 brightly. This makes it possible to brightly illuminate the side surfaces of the projecting portion 22b and the fixing member 32 that are not illuminated from the light emitting element 21a, are darker than the reflecting surface, and become shadows, and the observer looks up at the lighting fixture 10. In addition, the whole can be brightened.

  The light emitted from the light emitting element 21 a to the side passes through the housing portion 24 through the gap 22 c formed between the first reflecting portion 22 and the light emitting substrate 21, and to the side of the lighting fixture 10. proceed. As described above, the light to the side of the light emitting substrate 21 can be emitted from the housing portion 24 of the instrument body 20 without being disturbed by the first reflecting portion 22, so that the light spreading range is wide. Can be.

  By making the housing portion 24 a transparent member, the lighting fixture 10 can be seen from the inside, and the design can be improved, but the housing portion 24 contains a color material for coloring light. By coloring or painting, it can be colored in white light. Therefore, various effects can be nurtured.

Next, the connection member which connects the lighting fixture 10 is demonstrated based on FIG. 8 (A) and the same figure (B).
The connecting member 50 connects each lighting fixture 10.
The connecting member 50 has an E-shaped cross section, and the flange portion 24a of the housing portion 24 and the peripheral edge portion 25b of the front cover 25 are inserted into the gaps 51 on both sides along the longitudinal direction. Is done.

  In FIG. 8A and FIG. 8B, the connecting member 50 connects the short sides of the lighting fixture 10, but the long sides may be connected. Moreover, the connection member 50 connects each long side, connecting each short side of the lighting fixture 10, and connects the lighting fixture 10 in a column and a row, and is large sized illumination arrange | positioned in matrix form. It can also be an instrument
