Abstract

To provide an indirect illumination device capable of using liquid actually to perform space rendering using a water surface wave generated by a cymatics phenomenon of liquid.MEANS FOR SOLVING THE PROBLEM: Vibration generated by a loudspeaker (400) arranged at the bottom part of this device causes a cymatics phenomenon on a liquid level in a water tank with a lamp shade (200) as a wall surface. This water surface wave is used as a lens and projected onto the lamp shade (200) of a device body and the ceiling of a space where the device is installed by a power LED (300) arranged in the liquid of the water tank, thereby enabling indirect illumination using grid-like ripples with natural movement as illumination light.SELECTED DRAWING: Figure 1

Description

The present invention relates to an indirect luminaire that utilizes a liquid cymatics phenomenon.

Conventionally, indirect lighting that creates a space by indirect light is known. Indirect lighting is, for example, in which a light source is installed in a place invisible to the human eye, and indirect light is used as illumination light by irradiating and reflecting light toward a wall surface or a ceiling surface. (See, for example, Patent Document 1).
In addition, there is an indirect lighting that generates a wave on the liquid surface of the liquid and uses this as an expression of light.

In the above-mentioned prior case, it is necessary to create a mechanical device equipped with a dedicated end plate and a power source, and it is necessary to project light from diagonally above the device by a light source device suspended by an arm, so the projection direction is restricted. There is. For example, when trying to project in the vertical direction, the light source device itself becomes a shadow. Further, in a general light source device used for lighting, since the light emitting area of the light source is large, the light hits the wave of the image formation and the shadow portion between the waves and becomes blurred.

The present invention has been made in view of this point, and obtains an indirect illuminator having a more free projection direction by using a liquid cymatics phenomenon as an illuminating light having a natural movement with a simple structure. With the goal.

The cymatics indirect luminaire of the present invention is an indirect luminaire that projects light toward the lamp shade of the main body of the device and the ceiling of the place where the device is installed, and the lamp shade is housed in a water tank forming a wall surface. The liquid, the light source submerged in the liquid, and the liquid are vibrated by a sine wave to generate a cymatics phenomenon on the liquid surface, and the illumination light is projected onto the liquid to form an image with movement according to ripples. It is characterized by being provided with a vibration generator that can obtain the above.

In this device, a power LED (300) is installed in a water tank containing a liquid that also serves as a cooling device for the light source device, and a sine wave is input to the speaker (400) to vibrate the liquid, which is generated on the liquid surface. By illuminating the waves with light, it is possible to project the illumination light with the movement of the lamp shade (200) of the main body of the device and the description described in the prior art in the vertical direction. Further, by adjusting the frequency of vibration, it is possible to realize a lighting fixture capable of controlling the water surface wave of the liquid surface and changing the image formation of the projection surface.

Lighting fixtures are used in the form of being hung on a table or from the ceiling.

In order to achieve the above object, one aspect of the luminaire according to the present invention is a luminaire that is installed on a table or hung from the ceiling, and includes a lamp shade (200), a liquid to be put into the luminaire, and the above. Its main features are that it is equipped with a vibrating device (400) that generates a water surface wave on the liquid surface of the liquid and a power LED (200) installed at a position where the instrument body is submerged in the liquid.

As shown in FIGS. 1 to 3, the luminaire is an upper light type indirect luminaire in which the light source is submerged in a liquid, and includes a speaker (400), a storage unit (100) for accommodating the speaker (400), and a storage unit (100). Cylindrical part (200) that acts as a lamp shade for indirect lighting that diffuses light as well as a water tank wall that adheres to the speaker (400) to hold liquid, and copper for fixing the power supply and position. It consists of a power LED (300) suspended by a wire (500), these speakers (400), and a power cable (600) for supplying power to the power LED (300).

The storage unit (100) supports the lighting device from below so as to surround the peripheral edge of the speaker (400), and stores the lower part of the speaker and the copper wire (500) and the power cable (600) that supply the lighting and the power of the speaker. It has a hole for the power cable to pass through.
