Description

  The present invention relates to a lighting device installed on a beam-representing ceiling in which part or all of a structural beam is exposed.

  Beams (structural beams) that support the house along with the pillars are usually concealed by a ceiling plate or inner wall so that they cannot be seen from inside the room. The house which exposed is provided. Such a ceiling is called a beam ceiling or a ceiling. Wiring for lighting fixtures installed on general ceilings and light source drive devices are placed behind the ceiling plate so that they are not visible from inside the room, but there is no ceiling plate on the beam ceiling, so lighting fixture wiring, etc. Can't hide.

  On the other hand, Patent Document 1 proposes an illuminating device that uses a structural beam as a housing of a luminaire in a beam-represented ceiling in which a structural beam made of steel is exposed in a steel frame structure house. In this lighting device, a decorative plate having a vertical dimension larger than that of the structural beam is attached to both side surfaces of the structural beam, and a concave portion surrounded by a lower surface of the structural beam and two decorative plates is formed in the lower portion of the structural beam. A lighting fixture and wiring are accommodated in the recess. In this lighting device, since the wiring is not visible from the outside, it looks good. In addition, the indoor space can be made wider compared to a configuration in which the lighting device is fixed or suspended below the structural beam.

  On the other hand, in a wooden house, the purpose of using a beam as a ceiling is to make use of the texture and appearance of structural beams made of wood, in addition to widening the indoor space. Therefore, in the case of a beam-like ceiling of a wooden house, as in Patent Document 1, attaching a decorative plate to a structural beam in order to form a recess that accommodates a lighting fixture and wiring impairs the appearance of the structural beam. That is not preferable. In addition, unlike structural beams made of steel with a standardized shape, some structural beams made of wood do not have the same overall thickness, and it is difficult to attach decorative panels to such structural beams. .

  In the case of structural beams made of wood, it is conceivable to form a recess along the length direction by carving the lower part of the structural beam, and to accommodate lighting fixtures and wiring (or only wiring etc.) there. Will also damage the appearance of the structural beam. Considering the function of the structural beam to support the house, it is desirable to make the concave part as small as possible because forming the concave part in the structural beam leads to a decrease in the strength of the structural beam. It is difficult to illuminate the room sufficiently brightly with the light from the illuminated lighting equipment.

  The problem to be solved by the present invention is to prevent the appearance of a structural beam from being impaired when a lighting device is installed on a beam-appearing ceiling and to ensure sufficient brightness.

c) a translucent window formed on a side of the housing;
d) a first luminaire arranged in the housing and emitting light from the opening;
e) a second luminaire that emits light from the translucent window disposed in the housing.

Since the illuminating device according to the present invention is attached between the structural beams on the beam-representing ceiling, the appearance of the structural beam is not impaired .
In the lighting device according to the present invention, light from the first lighting fixture is radiated from an opening in the lower portion of the housing, and light from the second lighting fixture is radiated from a light transmitting window on the side of the housing. Thus, since light can be emitted from two places toward the room, the room can be illuminated brightly.

A so-called downlight can be adopted as the first lighting fixture. That is, in this structure, the 1st lighting fixture has the light source accommodating part attached to opening, the LED bulb attached to this light source accommodating part, and the drive device of the LED bulb arrange | positioned in the housing. In this configuration, the LED bulb can be exchanged through the opening.
The second lighting fixture may include an LED bulb and a driving device for the LED bulb. Thus, when an LED bulb is used as the light source for both the first and second lighting fixtures, temperature rise during lighting can be suppressed.

  In the present invention, it is also a good structure that a window portion is formed in the upper portion of the housing. According to this configuration, light from the second light source can be emitted upward from the window portion. Further, by providing the window at the top of the housing, even when the temperature of the first and second lighting fixtures rises during lighting, the heat can be efficiently discharged from the window.

  The illuminating device according to the present invention is particularly effective when installed on a beam-appearing ceiling of a wooden house. In this case, the housing is preferably formed from the same wood as the structural beam.

In addition, the beam display ceiling according to the present invention is
a) a plurality of structural beams arranged side by side in the horizontal direction;
b) the above-described lighting device attached between two structural beams located next to each other among the plurality of structural beams;
It is characterized by providing.

  According to the present invention, it is possible to install a lighting device on a beam-appearing ceiling without impairing the appearance of a structural beam. Since the light from the light source is emitted, the room can be made sufficiently bright.
