Description

  The present invention relates to a design illumination device, and more particularly to a design illumination device that dynamically emits light emitted from a light emitter.

  2. Description of the Related Art Conventionally, as a design illumination apparatus that dynamically irradiates light emitted from a light emitter, an apparatus using a mirror ball or an optical fiber has been proposed.

  By the way, this type of design lighting device is often used in a gorgeous place such as a party. For this reason, there is no device suitable for use in a restaurant or the like having a calm atmosphere.

  In view of the problems of the design lighting device that dynamically radiates the light emitted from the conventional light emitter, the present invention moves the light emitted from the light emitter capable of creating a calm atmosphere. An object of the present invention is to provide a design illumination device that is designed to irradiate automatically.

In order to achieve the above object, a design illumination device of the present invention is a design illumination device that is installed in a suspended manner, a plurality of light emitters that are light emitting diodes that are point light sources, a liquid reservoir, and a liquid reservoir. And a vibration generating means composed of a motor having an eccentric weight arranged on a vertical rotation shaft that causes movement of the surface of the liquid stored in the section, and the light emitted from the light emitter is stored in the liquid storage section. The liquid is transmitted through the surface of the liquid and irradiated so as to make a circular motion while the trajectory of the light fluctuates .

  In this case, the distance between the light emitter and the liquid reservoir can be made variable.

  Moreover, the bottom part of the liquid storage part can be formed in a curved surface.

  According to the design illumination device of the present invention, the surface of the liquid stored in the liquid storage unit is caused to move by the vibration generating unit, and the light emitted from the light emitter passes through the surface of the liquid stored in the liquid storage unit. By doing so, it is irradiated with fluctuation, and it is rich in design and can perform quaint illumination.

  Further, by changing the distance between the light emitter and the liquid storage unit, the light irradiation state can be changed, and different illumination can be performed by one apparatus.

  In addition, by forming the bottom of the liquid storage part in a curved surface, it is possible to clearly irradiate the irradiated object with an image of light emitted from the light emitter.

  Embodiments of a design lighting device according to the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the design lighting device of the present invention.
The design lighting device includes a light emitter 1, a liquid storage unit 2 that stores a liquid 3, and a vibration generating unit 4 as a unit that causes movement of the surface 31 of the liquid 3 stored in the liquid storage unit 2. The light emitted from the light emitter 1 is transmitted through the surface 31 of the liquid 3 stored in the liquid storage unit 2 and irradiated.

In this case, a light emitting diode which is a point light source can be used as the light emitter 1, and in this embodiment, a substrate 5 provided with a plurality of light emitters 1 is attached to an upper cover 6. ing.
A plurality of light emitters 1 can be arranged so as to form an appropriate shape, for example, a geometric pattern, a character, a figure, or the like, or light emitters of different emission colors can be used for the light emitter 1.

Any liquid such as water can be used as the liquid 3 stored in the liquid storage unit 2 (a liquid having a higher viscosity than water can be used in relation to the vibration generating means 4). If necessary, the liquid 3 can be replenished.
Note that the liquid 3 has a space in the upper part of the liquid storage unit 2 and is stored in such an amount as to cause movement on the surface 31 of the liquid 3 stored in the liquid storage unit 2 by the vibrating means 4.

The upper cover 6 to which the substrate 5 provided with the light emitter 1 is attached and the liquid storage unit 2 are configured to be variably configured with a plurality of shafts 7 therebetween.
Thereby, the irradiation state of light can be changed and different illumination can be performed by one apparatus.

The liquid storage part 2 is formed of a transparent material that transmits light emitted from the light emitter 1 and is colorless or colored in an arbitrary color.
Although the liquid storage part 2 is not specifically limited, in this embodiment, the bottom part 21 is stored in the liquid storage part 2 by forming a curved surface, more specifically, a substantially hemispherical shape. The liquid 3 functions as a lens so that it can clearly irradiate the irradiated object of the image of the light emitted from the light emitter 1.
In addition, the bottom part 21 of the liquid storage part 2 can be formed into a substantially hemispherical shape, a planar shape, a wave shape, or a prism shape.

A motor 41 having an eccentric weight 42 arranged on a rotating shaft can be used as the vibration generating means 4 as a means for causing a movement of the surface 31 of the liquid 3 stored in the liquid storage unit 2, and a design lighting device is suspended. It is arranged in the middle of the lowered power cord 8.
Thereby, the vibration generating means 4 including a power source can be configured easily.
In addition, the rotation speed of the motor 41 which comprises the vibration excitation means 4 is although it does not specifically limit, For example, it is set as the comparatively low rotation speed about several dozen-several hundred rpm.
In addition to the vibration generating means 4, a bubble generating device, an air flow generating device (fan), or the like can be used as a means for causing the surface 31 of the liquid 3 stored in the liquid storage unit 2 to move.

  According to this design illumination device, the surface 31 of the liquid 3 stored in the liquid storage unit 2 is regularly formed by the vibration generating means 4 as a means for causing movement of the surface 31 of the liquid 3 stored in the liquid storage unit 2. The light emitted from the light emitter 1 passes through the surface 31 of the liquid 3 stored in the liquid storage unit 2 and is irradiated with fluctuation as shown in FIG. 4 (arrows shown in FIG. 4). Shows an example of the trajectory of the irradiated light 9. The irradiated light 9 allows the distance between the upper cover 6 to which the substrate 5 provided with the light emitter 1 is attached and the liquid storage unit 2 to be variable. By doing so, it is possible to clearly irradiate the irradiated object 10 with an image of light emitted from the light emitter, or to radiate gently according to the use of the design lighting device. Can do quaint lighting.

  As described above, the design lighting device of the present invention has been described based on the embodiments thereof, but the present invention is not limited to the configurations described in the above embodiments, and the configuration is appropriately changed without departing from the gist thereof. Is something that can be done.

  Since the design lighting device of the present invention has a characteristic of being rich in design and capable of performing quaint lighting, it can be suitably used for lighting applications in restaurants with a calm atmosphere. In addition, it can be widely used for applications such as displays.
