A lighting device capable of stably floating that can detect the moving state of a floating lighting device or the state of sound outside the lighting device within the lighting device and change the light emission state depending on the moving state or sound state. The purpose is to provide.

In order to achieve the above object, a floatable luminaire according to the present invention emits light of a single color or a plurality of colors in a bag-like floatable luminaire into which a gas having a lighter specific gravity than air is injected. The light source includes a light source using one or a plurality of LEDs, a power source device that supplies power to the light source, and a control circuit that includes a sensor that senses movement of the lighting fixture.

In addition, an elongated string hangs down from the bag-like balloon, and a part of the string is grounded.

With the device of the present invention, the sensor of a floating balloon body, for example, an acceleration sensor, a gyro sensor, or a sound sensor, senses the movement of the floating body or the sound of the outside world, and It is possible to automatically adjust the ON / OFF, strength, and color of light according to movement or changes in the sound of the outside world. Since the device of the present invention can float freely, the presence / absence and strength of airflow, wind, or sound in a floating space can be expressed by ON / OFF, light intensity, and color of the light source. Is possible.

In general, the buoyancy of balloons decreases with the passage of time due to the release of gas with a lighter specific gravity than air. However, floating lighting fixtures include heavy light sources, batteries, sensors and circuits inside the balloons. Therefore, it becomes impossible to float in a relatively short time due to a decrease in buoyancy, as compared to general balloons. According to the present invention, when the levitation force of the balloon is lowered due to the slender string hanging from the bag-like balloon, the length of the grounded part of the string is increased, and as a result, the string on the balloon. The load becomes light and balances with the buoyancy of the balloon, making it possible to float stably at a desired height for a long time.

As shown in FIG. 1, a floatable lighting apparatus 10 according to the present invention includes a light source 2, a battery 3 that supplies power to the light source 2, a change in movement of the lighting apparatus, or an external environment. Light is emitted by a configuration including a sensor 4 that senses a sound state and a circuit 5 that connects them. The sensor 4 detects the moving state of the floatable lighting fixture 10 or the state of the external sound. Specifically, the sensor 4 receives signals from the tilt, acceleration, and sound sensors, and the light emission state of the light source 1 is ON-OFF, Or change strength or color.

The installation position of the light source 2 of the floatable lighting apparatus 10 according to the present invention, the battery 3 that supplies power to the light source 2, the sensor 4 that senses the movement of the lighting apparatus or the sound of the outside, and the circuit 5 that connects them is intended. Accordingly, as shown in FIGS. 1, 2, and 3, they may be installed anywhere in the balloon 1, and may not be fixed as long as they are in the balloon 1. When fixing to the center part of the balloon 1, it fixes in the balloon 1 with a thin tape and a rope like the string 6 of FIG.

Further, when the string 7 hangs down from the bag-like balloon 1 as shown in FIG. 1, FIG. 4 or FIG. 5, when the floating force of the balloon 1 decreases as shown in FIG. 5, the altitude of the balloon 1 decreases, The length of the grounding portion of the string 7 becomes longer, and as a result, the load of the string 7 on the balloon 1 becomes lighter than in the case of FIG. The instrument 10 can float at a desired height for a long time. The string 7 may be a tape or a rope.

It is a simulation figure (the light emission source is a balloon stopper part) of the internal structure of the floatable lighting fixture which concerns on this invention. It is a mimetic diagram (light-emitting source is the central part of a balloon) of the internal configuration of the floatable lighting apparatus according to the present invention. It is a mimetic diagram (light-emitting source is the other side of the mouthpiece part of a balloon) of the internal configuration of the floatable lighting fixture concerning the present invention.
