。[Function] In the present invention described in (1) above, by irradiating the liquid with ultrasonic waves, cavitation occurs in the liquid, and the generation and collapse of fine bubbles are repeated. When this bubble collapses, high pressure and high temperature are generated locally. This pressure and temperature causes the gas in the liquid to emit light, much like a gas flame. This light provides illumination in the liquid.
また、液体中に照射された超音波は、液体中での減衰が
極く微小であるため、距離が離れた場所まで到達し、広
範囲な照明が可能である。Further, since the ultrasonic waves irradiated into the liquid have extremely small attenuation in the liquid, they can reach places far away and illuminate a wide range.

きりとした照明が行なわれる。Furthermore, since straight forward flow unique to ultrasonic waves is generated in the liquid, contaminants in the liquid are removed, light scattering is suppressed, and clear illumination is achieved.

て発光し、十分な照明が行なわれる。In the present invention (2) above, in the present invention (1) above, gas is released into the liquid, and even when the gas content in the liquid is small, the gas contained in the liquid is released. In addition, the emitted gas emits light due to the pressure and temperature generated when microbubbles generated by cavitation collapse, providing sufficient illumination.

Light is emitted by the pressure and temperature generated when microbubbles collapse due to cavitation along with gas.
本発明の一実施例を第１図に基づいて詳細に説明する。 An embodiment of the present invention will be described in detail based on FIG.

構成されている。1 is a power source, 2 is an ultrasonic generator driven by the same power source 1, and 3 is a gas discharge device having a gas ejection port 4 into the liquid at its front end, the front end of which can swing around a point 5. It is configured as follows.

た光が発生し、これが照明用の光として利用される。In this embodiment, the front end of the gas emitting device 3 is swung around a point 5 by a device not shown, and gas such as hydrocarbons is emitted from the jet port 4 at the front end toward an arbitrary location in the limb that is desired to be illuminated. Then, an ultrasonic wave generator 2 driven by a power source 1 irradiates the area with ultrasonic waves. The irradiated ultrasonic waves cause cavitation in the liquid, which repeatedly generates and collapses microscopic bubbles. The time it takes for the fine bubbles to disappear is generally 1 μs or less, and a field with a local temperature of several thousand degrees and a pressure of 100 to 1000 atmospheres is formed. When exposed to the gases released in the field and the gases contained in the liquid, a light similar to a gaseous flame is generated, which is used for illumination.

て、従来よりもはっきりと照明することが可能である。In addition, when ultrasonic waves are irradiated into a liquid, the light has the property of moving in the direction of the ultrasonic wave, and has the effect of constantly moving dust and solid inclusions that are mixed in the liquid and are blocking the path of light. be. When only light is irradiated as in the conventional method, contaminants always remain in the same place.
The path of the light was blocked and the target location could not be seen clearly, but in this example, by moving the dust and solid inclusions in the direction of the ultrasonic wave and removing them as described above, it was possible to see the target location more clearly than before. It is possible to illuminate.
さらに、従来の方法では、照明個所が遠くなれば、光の
散乱によって光が届かないことがあった。Furthermore, in conventional methods, if the illumination location is far away, the light may not reach the illumination location due to light scattering.
しかし、本実施例における超音波の液体中での減衰は掻

なお、本実施例では炭化水素等のガスを液中へ放出する
ようにしているが、液体中に十分な量のガスが含有され
ている場合にはガス放出の必要はない。In this embodiment, a gas such as a hydrocarbon is released into the liquid, but if the liquid contains a sufficient amount of gas, there is no need to release the gas.
