  However, the above-described conventional lighting device is a combination of a fluorescent lamp and a speaker in which a general speaker unit is placed on a general lighting fixture using a fluorescent lamp, which is bulky and heavy. . For this reason, there is too much presence as indoor interior, leaving room for improvement.

  An object of the present invention is to provide a lighting device that has a sound source and is small in volume and light in weight, and that is preferable as a thin indoor interior.

  The illuminating device according to claim 1 is an illuminating device having a light source and a sound source, wherein the light source includes at least a first light source that emits light in a first direction, and in a light emission direction of the first light source. Is characterized in that a first diffusing member for diffusing a part of the light emitted from the first light source is provided.

It is a side view of the illuminating device of 3rd Example of this invention. It is a side view of the illuminating device of 4th Example of this invention. It is a side view of the illuminating device of 5th Example of this invention. It is a side view of the illuminating device of 6th Example of this invention.

  Hereinafter, an embodiment of the present invention will be described. An illuminating device according to an embodiment of the present invention is an illuminating device having a light source and a sound source, and the light source includes at least a first light source that emits light in a first direction. In the light emission direction, a first diffusing member for diffusing a part of the light emitted from the first light source is provided. Thereby, while having a sound source, the volume is small and light, and it is preferable as a thin indoor interior. Moreover, the light emitted from the light source by the diffusing member can be dimmed.

  The light source may include a second light source that emits light in a second direction different from the first direction. Thereby, the illumination mode can be variously changed, for example, illumination is performed using both the first light source and the second light source, or indirect illumination is performed using only the second light source.

  The sound source may emit sound in a second direction different from the first direction. Thus, for example, the first light source can illuminate downward, and the sound source can emit sound in a direction different from the downward direction to obtain an acoustic effect.

  The sound source may emit sound in the first direction. Thereby, for example, illumination can be performed downward with the first light source, and dynamic sound can be emitted downward with the sound source.

  In addition, a guide member that guides the sound emitted from the sound source in a direction different from the first direction may be provided. Thereby, a sound can also be guide | induced to a desired direction and a sound effect can also be heightened.

  The guide member may also serve as the diffusion member. Thereby, the number of parts can be reduced.

  Further, it may be configured to be used so that the first direction is a downward direction. Thereby, it becomes suitable for providing the said illuminating device in an indoor ceiling etc. and performing indoor illumination.

  Moreover, the sound emitted from the sound source may be guided in the horizontal direction of the lighting device by the guide member. Thereby, for example, while illuminating the light emitted from the light source downward, the sound effect can be enhanced by guiding sound in the lateral direction.

  Further, a second diffusing member that diffuses part of the light emitted from the second light source in the light emission direction of the second light source may be provided. Thereby, the light of the indirect illumination emitted from the second light source can also be dimmed.

  Further, the sound emitting surface of the sound source and the light emitting surface of the light source may be on substantially the same plane. Thereby, the thickness of the said surface direction of the said illuminating device can be made thin.

  Further, the first diffusion member may have a shape obtained by cutting an elliptical cylinder surface along its generatrix. Thereby, for example, when the illumination device is provided on the indoor ceiling or the like and is illuminated downward with the first light source, the side of the first diffusing member bulged in an elliptical arc shape is viewed from below. Therefore, the lighting device is excellent in the rounded appearance.

  Further, the first diffusion member may be a flat plate. Thereby, for example, when the lighting device is provided on the ceiling of the room and the first light source illuminates downward, the flat surface of the first diffusing member is viewed from below, so that the appearance is excellent. It becomes a lighting device.

  Further, the first diffusing member and the second diffusing member may have a shape obtained by cutting an elliptical cylinder surface along its generatrix. Thereby, for example, when the illumination device is provided on the indoor ceiling or the like and is illuminated downward with the first light source, the side of the first diffusing member bulged in an elliptical arc shape is viewed from below. Thus, the lighting device is excellent in appearance with a roundness, and the entire appearance of the lighting device is excellent in the lighting device due to the roundness of both diffusion members.

  The direction in which the sound emitted from the sound source is guided by the guide member may be open. Thereby, sound can be effectively emitted from the guide member.

  Further, the light source may be an organic light emitting element. Thereby, a light source becomes still thinner and the said illuminating device becomes still thinner.

  The light source may be composed of a plurality of light source units. Thereby, for example, the illumination mode can be variously changed by changing the light intensity and color of each light source unit.

  Further, the light source may be curved outward. Thereby, for example, the distance between the diffusion member and the light source can be made substantially constant by taking the diffusion member as a shape obtained by cutting the elliptical cylindrical surface along the generatrix and using the light source as a shape following the shape of the diffusion member.
