Description

  The present invention relates to an illuminating device that moves up and down in a hollow or floats, and in particular, is equipped with an LED and a propeller, which is a levitation device, in a bag filled with light gas of specific gravity, and the power is turned on and off in response to the sensor. The present invention relates to a floating illuminator that lifts and lifts a lighting fixture that has been lowered after the lighting fixture has been lifted and floated hollowly for a certain period of time.

Ordinary proving devices are mounted on the ceiling, mounted on the wall, or suspended from the ceiling depending on the purpose of irradiation. Some of them stand on the desk like a stand or are buried like a street light.
Some interior lighting can be placed directly on the floor. Decoratively, direct lighting or indirect lighting is limited. In fact, there is no conventional lighting fixture in which the lighting device itself moves. In addition, when it is desired to move the illumination itself for shooting or the like, the illumination is mounted on a moving device, and the illumination is moved by moving a moving body.

The indoor lighting has a clear target to be illuminated and is installed in a stationary state with respect to the lighting target, so there is no need to move the lighting device. Therefore, only lighting devices that are fixed near the power source have been developed.
When developing a movable lighting device, it is necessary to equip the battery that moves with the device as a power source when the lighting fixture is a direct current. Wiring in a possible form is necessary, and there is a problem that it is not possible to move away from the power source, and it is a fact that a lighting device that can be moved even in a small room could not be realized.

There is little need to move the interior lighting. Conventionally, even if it was requested to make the illuminator movable, it could only be realized with a battery. However, it was desired to make the illuminator movable instead of the battery indoors. In particular, the development of an apparatus that can realize the illuminating device to be floated in a room is expected.

  An object of the present invention is to provide a moving lighting device that floats in response to a sensor and floats in a hollow space.

In order to solve the above problems, a floating lighting device according to the present invention includes a bag body filled with a gas having a specific gravity lighter than air, a light emitting source installed in the bag body, and a lift installed in the bag body. The mechanism and the power supply control device are configured to balance (balance) the buoyancy of the filled gas and the weight of the balloon body including the light emitting source and the lifting mechanism.
Further, the bag body is a balloon body made of a translucent material, and has a structure that transmits the light rays of the light emitting source installed inside to the outside.
Further, the gas having a low specific gravity is composed of helium gas, and when the gas is filled, the balloon body floats in a hollow state (floating / floating).
Moreover, the light emission source equipped in the bag body is composed of one or a plurality of light emitting diodes that emit light of a single color or a plurality of colors.

The ascending mechanism is composed of two propeller bodies rotating downward mounted on both ends of a rod-like body mounted on the bottom of the bag body, and the lighting fixture body is driven by rotating the propeller by operating the power control device. It is a structure that rises and floats in the hollow and gradually descends by its own weight while maintaining the balance and floating in the hollow when the power is turned off.
The power supply control device has a structure that is automatically turned on and off by sensors that are sensitive to changes in the external environment, light and darkness, sound, and temperature.
Further, the power supply control device is turned on by the sensitivity of the infrared sensor, the optical sensor, the temperature sensor, and the sound sensor and is rotated for a set time, and the power supply is turned off after an appropriate time has elapsed or the sensor is sensed again. The sensor is activated in response to the movement of the object, the presence of sunlight (dawn) or absence (nighttime), the presence or absence of heat generation, the presence of the performance sound of the instrument, and the levitation rises and floats in the hollow, In the OFF state, it gradually descends due to its own weight.

As described above, according to the floating lighting device according to the present invention,
1 Filling the bag with a gas with a specific gravity lighter than air balances the light source and the balloon equipped with the lifting mechanism, and the balloon is floated upward by the operation of the lifting device. It became possible to make artificial light float.
2 Since the bag body filled with gas is a semi-transparent material, the light inside the bag body goes outside and creates a fantastic space where there is light that oscillates in the air.
3 Because it is filled with gas such as helium gas, which has a lighter specific gravity than air, the lighting fixtures float freely (floating / floating), so that there is an unprecedented floating lighting.
4. In addition, the light emitting source mounted in the bag body is a light emitting diode (LED), so that the weight of the lighting device can be reduced and floated, and the light emitting diodes are not limited to a single color but have a plurality of colors. By selecting, you can enjoy the emission of various colors. Since the color of light can be selected, it is possible to adopt an image color.

5 By driving the propeller provided at the bottom, it is lifted by electric power in addition to the floating state due to gas, so it can be floated as needed, and can be floated at any time and used for advertising I can do it.
6 It is also possible to provide a lighting device that rises and floats in response to the performance of music by installing a sensor that is sensitive to the movement of the outside world, light and darkness, sound, temperature, etc. to the power source that drives the propeller.
7 An infrared sensor, light sensor, temperature sensor, and sound sensor are provided to raise the lighting fixture, but it is possible to interrupt the rise by providing an operating time.

Hereinafter, the floating lighting device according to the present invention will be described in detail with reference to embodiments shown in the drawings. FIG. 1 is a side view of the floating lighting device of the present invention, FIG. 2 is a plan view of a light source, and FIG. 3 is a side view of a lifting mechanism and the light source. 4 is a side view of the power supply control device, and FIG. 5 is a plan view of the power supply control device.
The floating lighting device 10 according to the present invention includes a bag body 20, a light emission source 30, a raising mechanism 40, and a power supply control device 50. The bag body is filled with a gas having a specific gravity lighter than air. In this configuration, the balloon is equipped with a lifting mechanism and is balanced with its own weight, the light source inside the bag is turned on, and at the same time, the lifting mechanism is driven to float the illuminating device.

  The bag body 20 is made of a translucent material, and is formed in a balloon body 24 so as to be filled with a gas 22 to be described later. The translucent material is a material that transmits light emitted from the inside to the outside. It is not necessary to be translucent if the light is transmitted. desirable.

The gas 22 filled in the bag is filled with a gas having a lighter specific gravity than air. In view of safety, helium gas used for gas balloons is desirable.
The gas having a specific gravity lower than that of the air to be filled needs to balance (balance) the weight of the balloon body equipped with the light emitting source and the lifting mechanism and the buoyancy of the gas as a whole. By filling the gas, the balloon body equipped with the light emitting source and the lifting mechanism is levitated. Considering that the gas gradually leaks and dissipates, it is desirable that the gas filling amount in the normal state is such that the balloon body does not rise extremely and the balloon body lifts somewhat.
The balloon body 24 includes a bag body 20, a light emitting source 30, and a lifting mechanism 40.

The light source 30 includes a light-emitting diode (LED) 32. The kind and the number of light emitting diodes are not limited. Further, it is conceivable that the light emitting diode emits a single color or a plurality of colors.
Since the light emission of the diode and the driving of the raising mechanism are not directly related, the power source of the diode and the power source of the raising mechanism can be operated separately. In this embodiment, in order to simplify the apparatus, the lighting of the light emitting diode and the driving of the raising mechanism are set simultaneously.
As shown in FIG. 2, in this implementation, the diodes are radially arranged in eight directions in a straight line, but the LED arrangement is not limited to this, and the number and size are not limited to this.

The raising mechanism 40 is equipped at both ends of a rod-like body 42 attached to the bottom of the bag body. The ascending mechanism is composed of a propeller body 44 that is driven to rotate. In this embodiment, as shown in FIG. 3, two propeller bodies are provided at both ends of the rod-like body 42 so as to rotate downward. When the propeller is driven to rotate downward, the balloon body 24 starts to rise gently due to the levitation force of the propeller rotation, and the propeller rotates and floats until the power is turned off. However, since it reaches the ceiling indoors, the ascending range is limited. In addition, since there is an object to be illuminated, it is meaningless to illuminate the vicinity of the ceiling, so the range of ascending is limited by limiting the length of the power cord.
The configuration of the propeller body uses two wings in this embodiment, but a plurality of wings may be used.

The power supply control device 50 is an ON-OFF control device connected to various sensors. The power supply is automatically turned on and off by a sensor that is sensitive to changes in the outside world, changes in brightness, sound generation or temperature change. In the present invention, as shown in FIG. As a station on the desk or on the floor.
As a control method, a configuration of driving for a certain set time is possible, but a mechanism for performing an OFF operation by a sensor reaction may also be used.

There is no limitation on the type of sensor, but various types of sensors can be attached. Of course, a simple opening / closing device without a sensor may be used.
As the sensor, mounting of an infrared sensor, an optical sensor, a temperature sensor, a sound sensor, or the like can be considered. This makes it possible to automatically turn on and off by moving various objects, the presence of sunlight (dawn), or the absence (nighttime). It can be configured to start in response, float up and float in the hollow, and gradually descend due to its own weight in the OFF state.

Although the floating lighting device according to the present invention is configured to move up and down or simply float in terms of apparatus, a lateral movement is added to the rising and lowering by a lateral air flow caused by natural winds, and the room is irregularly floated. It is possible to make a movement that seems to be doing.
In addition, the air in the building for indoor ventilation or exhaust is always flowed by ventilation for supply and exhaust, ventilation for cooling and heating, supply of clean air from the air purifier, etc. Since it moves to the left and right by the airflow, a lateral movement is added in addition to the ascent and descent, so that it is possible to realize a state in which the hollow is floating freely without being fluttered.

  When used as a position display in a gymnasium or event venue, the lead wire can be set relatively long so that it can float to a high ceiling. In this case, it is necessary to balance the weight including the dead weight of the long lead wire, the amount of gas filling the balloon body, and the levitation force.
